Conversion surgery for gastric cancer with PM.

Area of Science:

• Surgical Oncology
• Gastrointestinal Oncology
• Peritoneal Carcinomatosis Management

Background:

• Peritoneal carcinomatosis in gastric cancer presents a significant challenge to patient survival.
• The role and efficacy of surgical intervention in this context remain debated.
• Optimizing treatment strategies is crucial for improving outcomes.

Purpose of the Study:

• To review existing literature on conversion surgery for gastric cancer with peritoneal carcinomatosis.
• To identify critical factors influencing the success of surgical intervention.
• To evaluate current surgical approaches and their potential impact on survival.

Main Methods:

• Systematic review of twenty studies focusing on conversion surgery.
• Analysis of key surgical parameters: response to chemotherapy, completeness of resection, and tumor burden.
• Examination of bidirectional treatment approaches aimed at enhancing chemotherapy response rates.

Main Results:

• Conversion surgery success is contingent upon pre-operative chemotherapy response, achieving complete tumor resection, and a low initial tumor burden.
• Development of bidirectional strategies aims to improve patient response to neoadjuvant therapies.
• Two distinct surgical strategies are currently employed, with ongoing trials to compare their efficacy.

Conclusions:

• The effectiveness of conversion surgery for gastric cancer with peritoneal carcinomatosis requires further investigation.
• Patient selection based on tumor burden and response to chemotherapy is paramount for surgical consideration.
• Ongoing clinical trials are expected to provide definitive evidence regarding the controversial role of surgery in this setting.
