Insights

Advanced gastric cancer (GC) prognosis remains poor despite molecular insights. This review explores molecular classifications and druggable targets for precision medicine, aiming to improve patient outcomes in GC treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Advanced gastric cancer (GC) has a poor prognosis despite recent innovations.
  • Current targeted therapies (Trastuzumab, Ramucirumab) offer limited systemic management improvements.
  • Tumor heterogeneity and complex genetics hinder effective precision medicine in GC.

Purpose of the Study:

  • To critically review molecular classifications of gastric cancer.
  • To summarize key druggable molecular drivers and their therapeutic implications.
  • To explore the role of new technologies in advancing GC treatment.

Main Methods:

  • Literature review of molecular classifications (TCGA, ACRG).
  • Analysis of identified molecular drivers and targeted therapies.
  • Discussion of precision medicine approaches and immunotherapy selection.

Main Results:

  • Despite numerous molecular drivers identified, clinical application remains limited.
  • Molecular classifications (TCGA, ACRG) enable a precision medicine approach.
  • Subgroup identification improves patient selection for immunotherapy.

Conclusions:

  • Novel molecular classifications offer a path toward precision medicine for gastric cancer.
  • Targeting specific molecular drivers holds therapeutic potential.
  • Further research is needed to overcome heterogeneity and optimize treatment strategies.

Cancer Therapies02:49

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
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...
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...

Cancer Vaccines01:30

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...
