Summary
Targeted therapy for colorectal cancer can lead to genomic changes. High plasma tumor mutation burden (TMB) after treatment may predict immunotherapy response in metastatic disease.
Area of Science:
- Oncology
- Genomics
- Immunotherapy
Background:
- Colorectal cancers often develop genomic alterations after targeted therapy.
- Tumor mutation burden (TMB) is being explored as a predictive biomarker for immunotherapy response in microsatellite-stable metastatic colorectal cancer.
Purpose of the Study:
- To contextualize a recent study on high plasma TMB following targeted therapy.
- To explore the implications of high plasma TMB for immunotherapy efficacy in colorectal cancer.
Main Methods:
- Review and contextualization of a recent study.
- Analysis of plasma TMB levels post-targeted therapy.
Main Results:
- High plasma TMB was observed in patients after targeted therapy.
- This finding has implications for predicting immunotherapy response.
Conclusions:
- Plasma TMB is a potential biomarker for immunotherapy in metastatic colorectal cancer.
- Further research is needed to fully understand the role of TMB in guiding treatment decisions.

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
480
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

01:29Drugs for Treatment of Ulcerative Colitis in IBD
449
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

02:56Treatment Resistant Cancers
3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
