1. Phase II LEAP Clinical Trial For mCRC (Mar.10/23)
Le but de cette étude est de déterminer la sécurité et l'efficacité de la thérapie combinée avec le pembrolizumab (MK-3475) et Levantine la levantine (E7080/MK-7902) chez les patients atteints de cancer du sein triple négatif (TNBC), de cancer des ovaires, de cancer gastrique, cancer colorectal (CCR), glioblastoma (GBM), or biliary tract cancers (BTC). Participants will be enrolled in initial tumor-specific cohorts, which will be expanded if adequate efficacy is determined. The trial is available at the Odette Cancer Centre and at the Princess Margaret Cancer Centre in Toronto as well as the following Centres throughout Canada: Abbotsford, BC; Winnipeg, MB; CHU de Quebec. For information, visit the link below.
2. TRK Fusion Cancer and How to Test for It (Mar.13/23)

3. A Phase II, Open-label, Multicenter, Study of an Immunotherapeutic Treatment for the MSI High CRC Metastatic Population (Mar.13/23)
L'objectif de cette étude est d'examiner l'efficacité du vaccin DPX-Survivac en combinaison avec les médicaments cyclophosphamide et l'immunothérapie Pembrolizumab in patients with solid cancers who are identified to be MSI-High. All patients will receive combination therapy of DPX-Survivac, cyclophosphamide, and pembrolizumab. Patients participating will know which treatment they are receiving. The trial is currently hosted at the Odette Cancer Centre, and a new site is opening at Mt. Sinai Hospital.
4. Phase III Study at the centre de cancérologie Odette Comparing Arfolitixorin vs. Leucovorin in Combination with 5FU, Oxaliplatin and Bevacizumab in Patients with Advanced CRC (Mar.12/23)
The purpose of this study is to look at the effectiveness of the drug Arfolitixorin in combination with 5-fluorouracil (5FU), oxaliplatin, and bevacizumab in patients with colorectal cancer (CRC). Patients with advanced/metastatic CRC who meet certain criteria may be able to participate. There will be two groups of patients participating in this study;
- un groupe recevra de L'arfolitixorine en combinaison avec du 5FU), de l'oxaliplatine et du bevacizumab,
- tandis que l'autre groupe recevra le médicament Leucovorin en combinaison avec le 5FU, l'oxaliplatine et le bevacizumab (norme de soins).
Le médecin et le personnel de l'étude ne sauront pas dans quel groupe se trouve un patient. Les patients seront répartis au hasard pour recevoir l'un ou l'autre traitement.
A propos d'Arfolitixorine:
L'arfolitixorine is Isofol’s proprietary drug candidate being developed to increase the efficacy of standard of care chemotherapy for advanced CRC. The drug candidate is currently being studied in a global Phase 3 clinical trial. As the key active metabolite of the widely used folate-based drugs, arfolitixorin can potentially benefit all patients with advanced CRC, as it does not require complicated metabolic activation to become effective.
Traiter les patients atteints de cancer avec de l'arfolitixorine - Les objectifs :
- When treating CRC, for example, arfolitixorin is administered in combination with 5-FU to increase cell mortality in circulating cancer cells and in cancerous tumours.
- Arfolitixorin is administered in conjunction with rescue therapy after high-dose treatment with the cytotoxic agent, methotrexate, in order to suppress the cytotoxic effect in surrounding healthy tissue. The treatment is used for certain types of cancer, such as osteosarcoma, a type of bone cancer. This involves administering arfolitixorin separately, 24 hours after the chemotherapy.

5. Compugen Begins Trial of TIGIT, PVRIG Inhibitors with Keytruda in CRC (Mar.6/23)
Compugen announced that the first patient with metastatic, microsatellite-stable colorectal cancer (CRC) has received treatment within a clinical trial exploring the efficacy of different regimens comprising its PVRIG and TIGIT inhibitors, and Merck’s checkpoint inhibitor Keytruda. Patients in the Phase I study will receive one of three treatments: just the TIGIT inhibitor COM902; COM902 plus the PVRIG inhibitor COM701; and COM902, COM701, plus Keytruda. The first patient treated in the trial received the triplet combination. Compugen aims to enroll 90 participants total, with up to 20 patients with microsatellite-stable CRC in the triplet arm. In this study, the company aims to build on positive data reported last year from a trial of COM701 plus Bristol Myers Squibb’s checkpoint inhibitor Opdivo (nivolumab) in microsatellite-stable CRC patients, according to Cohen-Dayag. The firm expects to report data from the latest Phase I trial of its drugs with Keytruda by the end of 2023.
6. Results from SUNLIGHT Study Point to Practice-Changing Care for Patients with Refractory mCRC (Jan.21/23)
Presented during the annual ASCO Gastrointestinal Cancers Symposium, January 19-21, results from the phase III SUNLIGHT study* could potentially change clinical practice in the third-line treatment of refractory metastatic colorectal cancer (mCRC). This open-label controlled two-arm, phase III comparison study was designed to validate the efficacy and safety of the orally administered combination of trifluridine/tipiracil plus monoclonal antibody bevacizumab versus standard of care trifluridine/tipiracil alone in the third-line treatment of 492 patients with refractory mCRC who had progressed after two lines of prior therapy.
Researchers reported an improved median survival of 3.3 months with trifluridine/tipiracil plus bevacizumab, from 7.5 months with trifluridine/tipiracil monotherapy to 10.8 months with the combination regimen. Progression-free survival was 2.4 months with trifluridine/tipiracil alone versus 5.6 months combined with bevacizumab. Time to deterioration in global health status was 4.7 months and 8.5 months, respectively. Quality of life was graded according to the ECOG Performance Status Scale. Median time to worsening to a grade 2 or more was 9.3 months with the combination compared with 6.3 months in those patients receiving trifluridine/tipiracil alone.
The data points to trifluridine/tipiracil plus bevacizumab as a new standard of care. This combination therapy could therefore open a much needed, more effective treatment avenue for patients with refractory mCRC who have progressed after two lines of therapy.

7. A Study of Nivolumab, Nivolumab Plus Ipilimumab, or Investigator’s Choice Chemotherapy for the Treatment of Participants with MMR-D/MSI-H mCRC (Nov.29/22)
The main purpose of this study is to compare the clinical benefit achieved by nivolumab monotherapy or by nivolumab in combination with ipilimumab in participants with Microsatellite Instability High (MSI-H) or Mismatch Repair Deficient (MMR-D) metastatic colorectal cancer (mCRC). This study will also compare nivolumab plus ipilimumab combination vs chemotherapy for treatment of MSI-H/MMR-D mCRC participants.
Participants will be randomly assigned to one of three arms: Arm A: Nivolumab Monotherapy, Arm B: Nivolumab + Ipilimumab Combination or Arm C: Investigator’s Choice Chemotherapy. The primary outcome measure is progression-free survival (PFS), while the secondary outcome measures include overall response rate (ORR) and overall survival (OS). This study is has an estimated completion date of June 10, 2026.

LES THÉRAPIES CHIRURGICALES
8. Hepatic Artery Infusion Pump (HAIP) Chemotherapy Program – Sunnybrook Odette Cancer Centre (Mar.1/23)
Le programme PPAH est une première au Canada pour les personnes dont le cancer du côlon ou du rectum (cancer colorectal) s'est propagé au foie et ne peut être retiré par une intervention chirurgicale. Le programme implique une approche coordonnée et multidisciplinaire des soins, avec une étroite collaboration entre l'oncologie chirurgicale, l'oncologie médicale (chimiothérapie), la radiologie interventionnelle, la médecine nucléaire et les soins infirmiers en oncologie. La pompe à perfusion de l'artère hépatique (PPAH) est un petit dispositif en forme de disque qui est chirurgicalement implanté juste sous la peau du patient et est relié par un cathéter à l'artère hépatique (principale) du foie. Environ 95 % de la chimiothérapie administrée par cette pompe reste dans le foie, épargnant ainsi le reste du corps des effets secondaires. Les patients reçoivent une chimiothérapie dirigée par PPAH en plus de la chimiothérapie intraveineuse (IV) régulière (chimiothérapie systémique), afin de réduire le nombre et la taille des tumeurs. Drs. Paul Karanicolas and Michael Raphael are the program leads and happy to see patients who may be eligible for the therapy.

Maintenant au centre de cancérologie Odette, le PPAH est utilisé chez les patients atteints d'un cancer colorectal qui s'est propagé au foie et qui ne peut être enlevé chirurgicalement et ne s'est pas propagé à d'autres parties du corps. Les patients qui ont peu (1-5) et de très petites tumeurs dans les poumons peuvent être pris en considération si la maladie pulmonaire est jugée traitable avant le PPAH. Si vous pensez pouvoir bénéficier de cette thérapie et/ou si vous souhaitez en savoir plus sur l'essai clinique, votre oncologue médical ou votre chirurgien peut vous adresser par télécopie au 416-480-6179.

9. Living Donor Liver Transplantation for Unresectable CRC Liver Metastases (Mar.2/23)
Environ la moitié des patients atteints de cancer colorectal (CCR) développent des métastases, généralement au niveau du foie et des poumons. L'ablation chirurgicale des métastases hépatiques (MH) est la seule option de traitement, bien que seulement 20 à 40 % des patients soient candidats à un traitement chirurgical. La thérapie chirurgicale apporte un avantage significatif en termes de survie, avec une survie à 5 ans après résection du foie de 40 à 50 % pour les MH, contre 10 à 20 % pour la chimiothérapie seule. La transplantation du foie (TF) permettrait d'éliminer toute maladie évidente dans les cas où les métastases colorectales sont isolées au foie mais considérées comme non résécables.

While CRC LM is considered a contraindication for LT at most cancer centers, a single center in Oslo, Norway demonstrated a 5-year survival of 56%. A clinical trial sponsored by the University Health Network in Toronto will offer live donor liver transplantation (LDLT) to select patients with unresectable metastases limited to the liver and are non-progressing on standard chemotherapy. Patients will be screened for liver transplant suitability and must also have a healthy living donor come forward for evaluation. Patients who undergo LDLT will be followed for survival, disease-free survival, and quality of life for 5 years and compared to a control group who discontinue the study before transplantation due to reasons other than cancer progression.

10. In Vivo Lung Perfusion (IVLP) for CRC Metastatic to Lung (Mar.9/22)
A new study is investigating a technique called In Vivo Lung Perfusion (IVLP) for delivering chemotherapy directly into the lungs at the time of surgery. Delivering chemotherapy directly to the lungs could potentially kill any microscopic cancer cells that are present in the lungs at the time of surgery, while sparing other major organs in the body from the side effects of chemotherapy.
At the University Health Network, this IVLP technique has been used recently in a Phase I study in patients with sarcoma, and they are now expanding on that experience to include patients with colorectal metastases. The purpose of this study is to test the safety of the IVLP technique and find the dose that seems right in humans. Participants are given oxaliplatin into one lung via IVLP and are watched very closely to see what side effects they have and to make sure the side effects are not severe. If the side effects are not severe, then more participants are asked to join the study and are given a higher dose of oxaliplatin. Participants joining the study later on will get higher doses of oxaliplatin than participants who join earlier. This will continue until a dose is found that causes severe but temporary side effects. The other lung will not be infused with anything, so that researchers can limit unforeseen toxicity to a single lung and see if one lung does better than the other.
The estimated enrolment is 10 participants, each with a diagnosis of colorectal carcinoma. The primary outcome is safety as measured by acute lung injury findings and the estimated primary completion date is January 1, 2027.

LES RADIOTHÉRAPIES/RADIOLOGIE INTERVENTIONNELLE
11. Study Offered at the Odette Cancer Centre to Treat Recurrent Rectal Cancer (Mar.9/23)
Magnetic resonance-guided focused ultrasound (MRg-FU) is a less invasive; outpatient modality being investigated for the thermal treatment of cancer. In MRg-FU, a specially designed transducer is used to focus a beam of low-intensity ultrasound energy into a small volume at a specific target site in the body. MR is used to identify and delineate the tumour, focus the ultrasound beam on the target, and provide a real-time thermal mapping to ensure accurate heating of the designated target with minimal effect to the adjacent healthy tissue. The focused ultrasound beam produces therapeutic hyperthermia (40-42°C) in the target field, causing protein denaturation and cell damage. Currently, there is no prospective clinical data reported on the use of MRg-FU in the setting of recurrent rectal cancer. Recurrent rectal cancer is a vexing clinical problem. Current retreatment protocols have limited efficacy. The addition of hyperthermia to radiation and chemotherapy may enhance the therapeutic response. With recent advances in technology, the investigators hypothesize that MRg-FU is technically feasible and can be safely used in combination with concurrent reirradiation and chemotherapy for the treatment of recurrent rectal cancer without increased side-effects. The study is being offered at the Odette Cancer Centre. Here is the link to the study protocol:

12. Trends in the Incidence of Young-Onset CRC with a Focus on Years Approaching Screening Age (Mar.10/23)
With recent evidence for the increasing risk of young-onset colorectal cancer (yCRC), the objective of this population-based longitudinal study was to evaluate the incidence of yCRC in one-year age increments, particularly focusing on the screening age of 50 years. The study was conducted using linked administrative health databases in British Columbia, Canada including a provincial cancer registry, inpatient/outpatient visits, and vital statistics from January 1, 1986 to December 31, 2016. Researchers calculated the incidence rates per 100,000 at every age from 20 to 60 years and estimated annual percent change in incidence (APCi) of yCRC using joinpoint regression analysis. 3,614 individuals were identified with yCRC (49.9% women). The incidence of CRC steadily rose from 20 to 60 years, with a marked increase from 49 to 50 years. Furthermore, there was a trend of increased incidence of yCRC among women. Analyses stratified by age yielded APCi’s of 2.49% and 0.12% for women aged 30-39 years and 40-49 years, respectively and 2.97% and 1.86% for men. These findings indicate a steady increase over one-year age increments in the risk of yCRC during the years approaching and beyond screening age. These findings highlight the need to raise awareness as well as continue discussions regarding considerations of lowering the screening age.

15. Young Adult CRC Clinic Available at Sunnybrook (Mar.5/23)
A recent study led by the University of Toronto doctors has observed a rise in colorectal cancer (CRC) rates in patients under the age of 50. The study mirrors findings from the U.S., Australia and Europe. The growing CRC rates iA recent study led by the University of Toronto doctors has observed a rise in colorectal cancer (CRC) rates in patients under the age of 50. The study mirrors findings from the U.S., Australia and Europe. The growing CRC rates in young people come after decades of declining rates in people over 50, which have occurred most likely due to increased use of CRC screening (through population-based screening programs) which can identify and remove precancerous polyps. Patients diagnosed under the age of 50 have a unique set of needs, challenges and worries. They are unlike those diagnosed over the age of 50. Dr. Shady Ashamalla (colorectal cancer surgical oncologist), along with Dr. Petra Wildgoose (Hepatobiliary and Colorectal Oncology Surgical Assistant), and their team at the du Centre des sciences de la santé Sunnybrook comprennent les besoins de cette population de patients.

16. CCRAN’s Partnership with “Count Me In” (Mar.1/23)
CCRAN is proud to partner with Count Me In, a nonprofit research initiative, on The Colorectal Cancer Project. This new project is open to anyone in the United States or Canada who has ever been diagnosed with colorectal cancer (CRC). Patients can find out more and join at JoinCountMeIn.org/Colorectal.
Through the project, patients are asked to complete surveys to share information about their experience with CRC, to share biological sample(s), and to allow for the research team to request copies of their medical records. The project team then de-identifies and shares data from these with the entire research community. 10
Every patient’s story holds a piece of the puzzle that can help us better understand CRC. By discovering more about what drives cancer and sharing this data, CCRAN and the Colorectal Cancer Project believe insights can be gained to develop more effective therapies. One of the aims of the project is to reach populations that have been understudied, including individuals who are diagnosed with CRC at a young age, individuals from marginalized communities who have historically been excluded from research, and patients with metastatic CRC. Together, we can accelerate our understanding of CRC. To learn more or sign up to participate, visit JoinCountMeIn.org/Colorectal.

“Count Me In”, a nonprofit cancer research initiative, is inviting all patients across the United States and Canada who have ever been diagnosed with colorectal cancer (CRC) to participate in research and help drive new discoveries related to this disease. The Colorectal Cancer Project will enable patients to easily share their samples, health information and personal lived experiences directly with researchers in order to accelerate the pace of research.
Patients who have been diagnosed with CRC at any point in their lives can join the project by visiting JoinCountMeIn.org/colorectal. From there, patients will be invited to share information about their experience through surveys and to provide access to medical records as well as saliva samples and optional blood, stool, and/or stored tissue samples for study and analysis. Researchers from the Broad Institute of MIT and Harvard and Dana-Farber Cancer Institute use this information to generate databases of clinical, genomic, molecular, and patient-reported data that is then de-identified and shared with researchers everywhere. To date, more than 9,000 patients with different cancers have joined Count Me In and shared their data. “We still do not know why there is an alarming rise in CRC in young adults”, said Andrea Cercek, MD Co-Director, Center for Young Onset Colorectal and Gastrointestinal Cancers Memorial Sloan Kettering Cancer Center and co-scientific leader of the Colorectal Cancer Project. “What we do know is that this is a global phenomenon that affects otherwise healthy individuals with no known risk factors. The Colorectal Cancer Project will provide researchers important information that will lead to a better understanding of this disease.”

Over 250 patients have joined the Colorectal Cancer Project since the launch in fall 2021. Every patient that joins the Colorectal Cancer Project enables us to learn more about colorectal cancer. Pts diagnosed at any age, whether newly diagnosed or years from their diagnosis, can enroll. If you have ever been diagnosed with colorectal cancer, you can visit JoinCountMeIn.org/Colorectal to enroll and have a direct impact on research and future treatment strategies.

Majd Ghadban and Julia Stoneman are co-leading a study to understand cancer patient experiences with using virtual care as a method of healthcare delivery during the COVID-19 pandemic. The study is being undertaken by a network of national oncology patient organizations in Canada known as CONECTed: Collective Oncology Network for Exchange, Cancer care innovation, Treatment access and Education.
More information about CONECTed can be found on its website: https://conected.io/
In addition to Majd Ghadban and Julia Stoneman, the study team includes Jessica Finucane, Ed.S., Dr. Ambreen Sayani, Postdoctoral Fellow – CIHR Patient-Oriented Research, Leadership Stream at the Women’s College Research Institute, Women’s College Hospital, Louise Binder, Health Policy Consultant, Save Your Skin Foundation and member of CONECTed’s Steering Committee, and Dr. Tim Ramsay, Scientific Director, Ottawa Methods Centre.
Study Purpose
The purpose of this study is to understand cancer patient experiences using virtual care during the COVID-19 pandemic, and to develop recommendations that will help to ensure adoption and adaptation of equitable, equal, consistent, and comprehensive virtual care best practices across Canada. To achieve the objectives of this project, one-on-one interviews will be conducted with cancer patients who have used virtual care during the COVID-19 pandemic as part of their cancer care. These interviews are offered in both English and French, for which an honourarium will be provided. Study findings will be used to develop reports, which will be made public. The findings will also be used to inform future studies in the area of virtual care and oncology.

21. Seven Ways Black Americans with mCRC Can Find Support (Feb.14/23)
If you are a person of African descent facing metastatic colorectal cancer (mCRC), here are ways to find support:
1. Ask your primary care doctor, oncologist, or other members of your care team about which services are available to you. There are organizations that can connect you with case managers, patient navigators or social workers. They can help you manage your appointments, finances, and insurance issues, as well as get you connected with programs that can help pay for housing and transportation and provide psychosocial support.
2. Reach out to family and friends. “If someone is offering to help you, let them help you — even if it’s just watching the kids for a while,” says Candace Henley, a Black woman and mother to five who was diagnosed with CRC at 34. Bring a friend or a family member to doctor appointments, she adds. “That person can ask questions and make sure everything has been heard and understood.”
3. Speak up. “Studies show that minority patient symptoms can be downplayed, attributed to other things, or misinterpreted,” says Heather Yeo, MD, a colon and rectal surgical oncologist at Weill Cornell Medicine in New York City. “This can mean you don’t get needed help in managing side effects from cancer treatments.” If you experience outright racism, report it to the management at the care center, says Henley. “Nothing ever changes if we don’t report it.”
4. Find online resources. Reach out to national organizations such as Fight Colorectal Cancer, the Colon Cancer Coalition, and the Colon Cancer Foundation and Henley’s Blue Hat Foundation.
5. Look to your faith. “For those with religious or spiritual beliefs, faith can be quite comforting,” says Henley. “Prayer can give us peace to accept the situation.”
6. Keep up healthy habits. It may not be easy, but do your best to sleep well, get enough exercise, and eat healthy — all of which will help with your recovery, says Dr. Yeo.
7. Keep hope alive. “I have a lot of hope for people with mCRC,” says Yeo. “I have patients who have had metastatic cancer and who I am taking care of for more than 10 years. Some are cured. With better understanding of cancer genetics, immune therapies and surgery, we are making progress.”

22. The Psychological Toll of Surviving CRC (Feb.21/23)
More and more patients are surviving colorectal cancer (CRC) long term, thanks to advances in treatment. A new study addresses a little-understood aspect of these survivors’ experience: the emotional aftermath.
Within a sample of 220 CRC patients who had participated in a previous randomized control trial, the study found that, even many years after their diagnosis, one third of respondents characterized their worst experience during their illness as “psychological distress,” referring primarily to anxiety regarding the uncertainty of their prognosis. About 17% cited “indigestion and discomfort during defecation,” and 16% cited receiving the cancer diagnosis itself as their worst experiences. In addition, among patients with a history of stoma, 36% said that the stoma was the worst part. On the other hand, 45% of patients reported that a “change in life priorities” was the most positive aspect of surviving colorectal cancer. One in four survivors said they were grateful for the support they received from their medical team.

The researchers behind the study noted that they hope their work will help cancer programs improve both patient care and aftercare. These issues can inform aftercare in three key ways: the surveillance plan for their cancer — meaning frequency of their bloodwork, imaging, and follow up visits; diet, wellness, and lifestyle changes that can reduce their risk for cancer recurrence, which are often underdiscussed; and mitigating the short- and long-term side effects, and residual effects, of the treatments that they received.

1. Be Your Own Advocate. Inform yourself about colon cancer before you see your doctor. Try your best to understand your stage, range of treatment options, and the potential role of precision cancer medicines.
2. Strongly consider a second opinion. Getting a second opinion from a colon cancer expert will help you understand ALL available treatment options and provide reassurance to you and your family that you are receiving the most appropriate therapy.
3. Ask about the role of precision medicines. Unlike traditional chemotherapy, which attacks any cell in the body that is rapidly dividing, precision cancer medicines target specific genetic alterations that allow cancer cells to grow. Most or all colon cancers result from abnormal genes or gene regulation. The strategy of precision cancer medicine is to define abnormalities at the most basic genetic level. These abnormalities in the DNA are called genomic alterations and they are responsible for driving cancer cell growth.
4. Join an online support community. An online community can be a great resource to help find a doctor, share information and learn about treatment choices with other individuals in your situation.
5. Ask About ctDNA Testing. Cancer is caused by genetic mutations, and these mutations can be detected by measuring circulating tumor DNA, or ctDNA, in the blood. Detection of ctDNA allows for personalized cancer surveillance based on an individual’s unique set of tumor mutations.
6. Bring written questions to your visit. A doctor’s visit is stressful, it is much easier to bring a list of written questions to ensure they all get answered and none are forgotten. Bring someone with you to take notes or consider using a recorder so you can listen and engage your doctor carefully.
7. Be organized. To stay on top of the treatment routine, it’s critical to record notes from doctor appointments, questions/answers for your physician, dates of appointments, test results blood cell counts, medications and dosing schedules, prescription refills and other information.
8. Make sure you understand the treatment outcomes. Your doctor should be able to tell you what you chance of survival/cure is if you elect to receive no treatment then explain how each proposed treatment improves upon that outcome.
9. Ask about clinical trials. By learning about clinical trials, you can identify opportunities that advance the treatment of colon cancer and possibly benefit your personal prognosis.
10. Build your CRC treatment team. For anyone diagnosed with CRC, the first step is to gather the right people to ensure that you’ll receive the best treatment possible. Research has shown that people with CRC are more likely to get the best results if they have a good team of medical specialists taking care of them.
24. Understanding MSI-High and DNA Mismatch Repair (Feb.10/23)
Microsatellite instability (MSI) is the condition of genetic hypermutability or a predisposition to mutations in cells that results from the bodies impaired DNA mismatch repair (dMMR) mechanism. DNA MMR is an essential function and the way the body naturally corrects errors that spontaneously occur during cell division associated DNA replication.
Microsatellite unstable cancers can be divided into two distinct MSI phenotypes: MSI-high (MSI-H) and MSI-low (MSI-L). MSI-H cancers are more likely to respond to certain treatments, especially with immunotherapy. MSI-H is caused by the absence of certain proteins which help repair DNA in cells when it breaks. When these are absent or not working properly a healthy cell can’t repair itself normally and it starts making many mistakes in its own genetic code. This disordered repair and growth is the hallmark of cancer. Colorectal cancer (CRC) is the disease most commonly associated with MSI-H, but essentially any cancer can be implicated. It is abnormality found in about 15% of colon cancers and other cancers. MSI-H colon cancers are best treated with a certain type of immunotherapy called checkpoint inhibitors which are more effective than chemotherapy.
Since MSI-H is frequently associated with genetic deficiencies that can be hereditary, it is important to understand the implications for family members. MSI-H findings on a cancer can also be sporadic, meaning that they don’t always change a family member’s risk of developing the same types of cancer.

25. Levels of Cell-Free DNA Do Not Impact ctDNA Detection in Patients with CRC (Jan.21/23)
A large-scale study using real-world data from patients with resected colorectal cancer (CRC) found that the levels of cell-free DNA (cfDNA) in plasma do not appear to significantly affect circulating tumor DNA (ctDNA) detection. Additionally, standard testing windows for minimal residual disease (MRD) could start as early as 15 days postoperatively.
The use of ctDNA to monitor MRD in patients with CRC has increased in the last several years. It is also known that cfDNA, which arises from normal tissue, can be elevated postoperatively and when patients receive adjuvant chemotherapy. The concern is that in the immediate postoperative period (when you know that there is going to be higher cfDNA) that it is going to be harder to detect ctDNA. As a reaction, many people were not evaluating ctDNA until 4 weeks after surgery. Waiting too long to test can lead to delays in treatment. This study was undertaken to understand how cfDNA levels and the timing of blood samples impact MRD monitoring for patients who undergo colon cancer surgery.
Results demonstrated that the levels of cfDNA were noticeably greater in the 2-week period immediately after surgery and when patients were receiving adjunctive chemotherapy. In addition, cfDNA concentrations 2 to 4 weeks after surgery were slightly greater than those seen in the 4- to 8-week time frame. In the first 2 weeks after surgery, when cfDNA concentrations were higher, ctDNA was detected in approximately 18% of patients. When analyzing the data in the period > 2 weeks postoperatively, ctDNA detection rates were consistent from weeks 4 to 8.
One of the factors that the researchers evaluated was whether baseline cfDNA impacted ctDNA positivity, and they found that it did not. There was no association between cfDNA concentration and ctDNA positivity. ctDNA positivity 2 to 8 weeks after surgery and in the surveillance, period was associated with significantly worse recurrence-free survival compared with patients who were negative for ctDNA. ctDNA positivity remains a strong predictor of recurrence. Researchers plan to look further to see where ctDNA is additive for clinical practice. While MRD testing for colorectal cancer has yet to become the standard of care for patients with resected localized disease, this study further opens the possibility of doing this testing earlier after surgery.

26. Exercise for Cancer to Enhance Living Well (EXCEL) Study (Mar.11/23)
Exercise for Cancer to Enhance Living Well (EXCEL) is a 5-year Canada-wide project, which offers free, 12-week exercise classes designed specifically for individuals undergoing or recovering from cancer treatment. Classes are online through a secure video-conferencing platform, and where possible, in-person (post-COVID). Physical activity can help overcome treatment-related side effects such as fatigue and pain, improve mental health by reducing anxiety and depression, and improve overall quality of life for individuals living with and beyond cancer. Studies show that physical activity may even reduce the risk of recurrence for some cancers. Many urban centres in Canada offer cancer-specific exercise programs, however, rural and remote areas tend to lack exercise resources to support cancer survivors, resulting in lower activity levels, poorer health, and diminished quality of life. Thus, EXCEL targets cancer survivors living in rural and remote regions across Canada, empowering them to move more and providing opportunities to benefit from physical activity.

27. The Association Between Stroke Belt Residence, CRC Incidence, and Diet (Feb.20/23)

Processed and red meat consumption has been identified as a significant risk factor for colorectal cancer (CRC). Since there are several ethnic and racial differences in CRC cases, trends in food intake, and regions of residence, extensive data is required regarding the association between living in areas having high CRC incidence and stroke levels and consumption of red and processed meat. Researchers explored the correlation between residing in Stroke Belt states (Alabama, Arkansas, Georgia, Indiana, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, and Virginia) and the incidence quartiles of CRC with dietary consumption.
The study results showed that participants reported the consumption of an average of 6.95 meat servings, with red meat consumed at 3.42 servings over the past week. Also, around 15.4 servings of healthy foods were ingested in the past week. The team noted that residence in a Stroke Belt state was substantially associated with greater red meat intake but not with the consumption of healthy foods. Residing in CRC states was not notably related to red meat or meat consumption. However, residing in Q2 CRC states (California, Idaho, Minnesota, Missouri, Texas, Wisconsin, North Carolina, Michigan, Connecticut, Maryland, Massachusetts, Maine, and Hampshire with the second lowest incidence of CRC) was significantly related to the highest consumption of healthy foods.
Therefore, study findings revealed that both total and red meat intake are influenced by geographic location. Public health interventions targeting lowering diet-related health disparities must consider the interaction of geography and meat consumption. The researchers believe that the association of dietary habits with structural and systemic influences underscores the significance of continuing to assess the relationship between diet choices and diet-related health problems and identifying protective variables that can be employed in public health interventions.
MISES À JOUR COVID-19
28. Regardless of the Variant, Prior Infection Holds Up Against Severe COVID (Feb.17/23)

Previous SARS-CoV-2 infection offered strong protection against severe disease from a subsequent reinfection, with little difference observed between strains, though prior Omicron BA.1 infections were less protective against another reinfection.
This systematic review and meta-analysis included 65 studies from 19 countries, including retrospective and prospective cohort studies and test-negative case-control studies published up to Sept. 31, 2022. Any study with results on the protective effect of natural immunity in individuals who were not vaccinated in comparison with those who were not vaccinated and COVID-naive were included, as were studies that included individuals controlled for vaccination status. Any study that included hybrid immunity was excluded.
Mean pooled effectiveness against reinfection or symptomatic reinfection was 82% or higher for the pre-Omicron strains compared with about 45% for the Omicron BA.1 variant. While protection from reinfection from the pre-Omicron strains declined over time, it remained high, at 78.6% at 40 weeks versus 36.1% for Omicron BA.1, researchers noted. The analysis suggests that the level of protection from past infection by variant and over time is at least equivalent if not greater than that provided by two-dose mRNA vaccines. These data have implications for future guidance on when to get a booster dose, they added. Researchers note it supports the idea that those with a documented infection should be treated similarly to those who have been fully vaccinated with high-quality vaccines.

29. Frequently Asked Questions for COVID-19
Q: What is COVID-19 (or novel Coronavirus Disease – 19)?
A: Coronaviruses are a large family of viruses that can cause illnesses in humans and animals. Coronaviruses can cause illnesses that range in severity from the common cold to more severe diseases such as Severe Acute Respiratory Syndrome (SARS) and most recently, COVID-19. COVID-19 or novel coronavirus originated from an outbreak in Wuhan, China in December 2019. The most common symptoms associated with COVID-19 can include fever, fatigue, and a dry cough. Though additional symptoms have now been linked with the disease, which may include aches and pains, nasal congestion, runny nose, sore throat, diarrhea, skin rash and vomiting. It is also possible to become infected with COVID-19 and not experience any symptoms or feeling ill. The spread of COVID-19 is mainly through the transmission of droplets from the nose or mouth when a person coughs, exhales or sneezes. These droplets land on surfaces around a nearby person. COVID-19 can be transmitted to that nearby person who may end up touching the surface contaminated with COVID-19 and then end up touching their nose, mouth, or eyes. A person can also contract COVID-19 through inhaling these droplets from someone with COVID-19. Although research is still ongoing, it is important to note that older populations (over the age of 65), those with a compromised immune system and those with pre-existing conditions including heart disease, high blood pressure, lung disease, diabetes or cancer may be at a higher risk of severe illness due to COVID-19.

Q: What can I do to avoid getting Coronavirus?
A: There are various ways in which we can reduce our risk of contracting COVID-19. Below are some measures suggested by the World Health Organization
1. Keep at least 2 metres (or 6 feet) between yourself and other people. This will reduce the risk of inhaling droplets from those infected with COVID-19.
2. Regularly clean your hands for at least 20 seconds with warm water and soap, or an alcohol-based hand rub. This will kill any viruses on your hands.
3. Avoid touching your eyes, nose and mouth. If the virus is on your hands, it can enter the body through these areas.
4. Follow good respiratory hygiene by covering your mouth and nose with a tissue or elbow when you cough and sneeze. This prevents the droplets from settling on surfaces or being released into the air around you.
5. Stay home as much as possible, especially if you are feeling unwell. If you think you may have the Coronavirus, please see “What should I do if I think I have Coronavirus?” section.
6. Please wear a face covering or mask in public when physical distancing is not possible.

Y a-t-il des précautions particulières que les personnes atteintes d'un cancer peuvent prendre ?
R : Les personnes atteintes de cancer (et d'autres maladies chroniques telles que les maladies cardiaques, le diabète, l'hypertension et les maladies pulmonaires) sont plus exposées à une maladie grave en raison de la COVID-19, le cancer étant considéré comme un problème de santé préexistant. Certains traitements contre le cancer, notamment la chimiothérapie, les radiations et la chirurgie, peuvent affaiblir le système immunitaire, ce qui rend l'organisme plus difficile à combattre les infections et les virus, comme le Coronavirus. Il est important de suivre avec diligence les recommandations de l'Organisation mondiale de la santé ci-dessus pour réduire le risque de contracter le COVID-19. Si vous avez des inquiétudes quant à votre risque, il est préférable de contacter votre médecin ou votre équipe de soins.
Y a-t-il des changements en ce qui concerne mes visites médicales liées au cancer ? Chaque patient et chaque plan de traitement étant uniques, il est toujours préférable de contacter votre prestataire de soins de santé pour obtenir des informations actualisées sur votre plan de traitement. Dans certains cas, il est possible de retarder le traitement du cancer jusqu'à ce que le risque de pandémie ait diminué. Dans d'autres cas, il peut être sûr de se rendre dans une clinique distincte de celle où sont traités les patients COVID-19. Les options de traitement oral pourraient être prescrites par votre prestataire de soins de manière virtuelle, sans qu'il soit nécessaire de se rendre à la clinique. Enfin, certains rendez-vous ou discussions de suivi pourraient être organisés virtuellement (via skype ou zoom par exemple) ou par téléphone pour minimiser votre risque. Comme nous le savons, les conditions et les protocoles changent quotidiennement en raison de la nature de l'épidémie de COVID-19 et varient en fonction du lieu, par conséquent, la meilleure première étape consiste à demander conseil à votre prestataire de soins.
