Insights

New targeted drugs show promise for advanced gastric cancer, offering a potential new treatment avenue. This review synthesizes data on their efficacy and safety in patients with unresectable or metastatic disease.

Area of Science:

  • Oncology
  • Gastroenterology
  • Pharmacology

Background:

  • Gastric cancer is a leading cause of cancer death, with most patients diagnosed at advanced stages.
  • Current treatment options for advanced gastric cancer have limited efficacy, highlighting the need for novel therapeutic strategies.
  • Molecularly targeted agents are emerging as a promising approach to treat this disease.

Purpose of the Study:

  • To systematically review and synthesize available trial data on the efficacy and safety of molecularly targeted drugs.
  • To evaluate the potential of these agents in patients with unresectable and metastatic gastric cancer.
  • To provide an overview of ongoing clinical development for novel gastric cancer treatments.

Main Methods:

  • Systematic literature review of clinical trials.
  • Synthesis of efficacy and safety data for molecularly targeted drugs.
  • Focus on agents targeting signal transduction pathways in gastric cancer.

Main Results:

  • Molecularly targeted drugs are under clinical development, targeting pathways like angiogenesis, EGFR, cell cycle, MMPs, COX-2, mTOR, and proteasome.
  • This review is the first to consolidate data on these agents for advanced gastric cancer.
  • The data synthesized will inform the assessment of these novel therapies.

Conclusions:

  • Molecularly targeted agents represent a promising future direction for gastric cancer treatment.
  • Further development and assessment of these agents are crucial for improving outcomes.
  • Understanding the molecular mechanisms of gastric carcinogenesis is key to advancing therapy.

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 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...

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...
