Abstract

Insights

Targeted therapies like monoclonal antibodies improve outcomes for advanced gastrointestinal cancers. Anti-epidermal growth factor receptor (EGFR) and anti-vascular endothelial growth factor (VEGF) antibodies show promise, especially when combined with chemotherapy.

Area of Science:

  • Gastrointestinal Oncology
  • Molecular Targeted Therapy
  • Cancer Biomarkers

Background:

  • Colorectal and gastric neoplasms are leading gastrointestinal cancers.
  • Targeted drug development has enhanced systemic therapy for advanced stages.
  • Key biological pathways include angiogenesis and epidermal growth factor receptor (EGFR) signaling.

Purpose of the Study:

  • To review biological processes in gastrointestinal cancer.
  • To discuss anti-EGFR and anti-VEGF monoclonal antibodies in colorectal and gastric cancers.
  • To report on emerging monoclonal antibodies in development.

Main Methods:

  • Literature review of biological processes in gastrointestinal cancer.
  • Analysis of anti-EGFR and anti-VEGF monoclonal antibody efficacy.
  • Inclusion of data on novel monoclonal antibodies.

Main Results:

  • Monoclonal antibodies combined with chemotherapy yield best outcomes in colorectal and gastric cancers.
  • Single-agent anti-EGFR antibodies show activity in specific metastatic colorectal cancer (CRC) settings.
  • Data on anti-VEGF/anti-EGFR addition to chemotherapy for resectable metastases is limited.
  • Adjuvant setting data for these therapies is scarce and conflicting.

Conclusions:

  • Patient selection tests are available for targeted therapies.
  • Further biomarker evaluation is crucial for personalized systemic therapy.
  • Tailorization of treatment based on biomarkers is essential for optimizing outcomes.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

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.
There are several types of targeted therapies against specific...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
Tumor Immunotherapy01:27

Tumor Immunotherapy

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.
Treatment Resistant Cancers02:56

Treatment Resistant Cancers

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...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

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 Disease...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
Pharmacologic...
