Abstract

Insights

Targeted therapies show promise for advanced gastric cancer, but more research is needed. Randomized trials and biomarker studies are crucial to identify effective treatments and patient subgroups for gastric cancer therapy.

Area of Science:

  • Oncology
  • Gastrointestinal Oncology
  • Cancer Therapeutics

Background:

  • Advanced gastric cancer treatment relies on chemotherapy, with limited survival benefits.
  • Combination chemotherapy shows modest response rates but fails to significantly extend progression-free or overall survival.
  • Targeted therapy development in gastric cancer lags behind other cancers like colorectal cancer.

Purpose of the Study:

  • To review the current experience and recent advancements in targeted therapies for advanced gastric cancer.
  • To highlight the progress and challenges in integrating novel agents into gastric cancer treatment paradigms.

Main Methods:

  • Review of recent publications focusing on targeted therapies in advanced gastric cancer.
  • Analysis of data from nonrandomized phase I and II trials.

Main Results:

  • Current research on targeted therapies is primarily based on nonrandomized phase I/II trials.
  • Angiogenesis inhibitors and agents targeting epidermal growth factor receptors (EGFR1 and HER2) are the main classes of targeted agents investigated.

Conclusions:

  • Robust, randomized phase III trials are essential to establish the clinical utility of targeted therapies in advanced gastric cancer.
  • Biomarker studies are critical for identifying patient populations who will benefit most from targeted and chemotherapy combinations.

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...

Cancer Vaccines

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...
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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
