Gastric cancer: factors affecting survival

Area of Science:

• Oncology
• Surgical Oncology
• Gastroenterology

Background:

• Gastric cancer (GC) remains a significant global health challenge.
• Surgical resection is a primary treatment modality for resectable GC.
• Identifying prognostic factors is crucial for improving patient outcomes.

Purpose of the Study:

• To determine factors influencing survival in patients undergoing surgery for gastric cancer.
• To analyze the impact of surgical technique and patient-specific variables on GC prognosis.

Main Methods:

• Retrospective analysis of 234 patients who underwent elective surgery for GC.
• Data collected included demographics, tumor characteristics, surgical details, and survival outcomes.
• Statistical analysis to identify significant predictors of survival.

Main Results:

• Favorable survival associated with smaller tumor diameter (<4 cm), lower tumor localization, senior surgeon experience, absence of lymph node metastasis, lower tumor grade, and decreased invasion depth.
• Metastatic lymph nodes significantly increased mortality and decreased survival.
• Harvesting 16 or more lymph nodes correlated with increased mortality.
• Higher disease stage was linked to decreased survival and increased mortality.
• No significant difference in survival between D1 and D2 lymph node dissection (LND).

Conclusions:

• Surgeon experience is a key factor in survival outcomes for resectable gastric cancer.
• Patient-related factors, including tumor size, T stage, and lymph node metastasis, significantly affect survival.
• Optimizing surgical approach and patient selection can improve outcomes in gastric cancer treatment.
