Gastric cancer adjuvant therapy.

Area of Science:

• Oncology
• Gastroenterology

Background:

• Gastric cancer is a significant global health burden, particularly lethal and highly prevalent in East Asia.
• High relapse rates after curative resection for stages II and III gastric cancer necessitate effective adjuvant and neoadjuvant strategies.
• Treatment approaches vary significantly between Western and East Asian countries.

Purpose of the Study:

• To review the current landscape of gastric cancer treatment, focusing on the role of chemotherapy and radiation therapy.
• To highlight the established efficacy of perioperative chemotherapy in Western populations for locally advanced disease.
• To identify the need for further research into the role of radiation therapy in gastric cancer management.

Main Methods:

• Systematic review of existing literature on gastric cancer treatment modalities.
• Analysis of data regarding adjuvant and perioperative chemotherapy outcomes in different global regions.
• Evaluation of the current evidence for radiation therapy in neoadjuvant and adjuvant settings.

Main Results:

• Adjuvant chemotherapy has demonstrated positive results, particularly in East Asian populations.
• Perioperative chemotherapy is the standard of care in the Western World, enhancing the likelihood of curative resection.
• The precise role and optimal application of radiation therapy remain to be elucidated through further rigorous studies.

Conclusions:

• Perioperative chemotherapy is a crucial component of gastric cancer management in the West.
• Further high-quality research is required to define the role of radiation therapy in gastric cancer treatment protocols.
• Optimizing treatment strategies, including chemotherapy and potentially radiation, is essential for improving outcomes in gastric cancer patients worldwide.
