[PROGNOSTIC SURVIVAL FACTORS IN GASTRIC CANCER WITH NEGATIVE REGIONAL NODES]
Summary
Extended lymphadenectomy and early detection significantly improve survival rates for node-negative gastric cancer patients. Curative resection and specific lymphadenectomy types are key prognostic factors.
Area of Science:
- Oncology
- Surgical Gastroenterology
Background:
- Gastric cancer remains a significant global health challenge.
- Node-negative gastric cancer presents unique prognostic considerations.
- Understanding prognostic factors is crucial for patient stratification and treatment planning.
Purpose of the Study:
- To identify prognostic factors influencing the five-year survival rate in node-negative gastric cancer patients.
- To evaluate the impact of different lymphadenectomy types on patient outcomes.
- To determine key parameters for stratifying patients for adjuvant therapies.
Main Methods:
- Retrospective analysis of 44 node-negative gastric cancer patients.
- Evaluation of surgical procedures including subtotal and total gastrectomy.
- Analysis of lymph node dissection types (D0, D1, D2/D3) and their correlation with survival.
- Univariate analysis using the log-rank test to assess prognostic factors.
Main Results:
- The overall 5-year survival rate was 38%, increasing to 56% with D1-D3 lymphadenectomy.
- Prognosis was significantly associated with serum hemoglobin levels, clinical stage, curability, and lymphadenectomy type.
- Age, gender, tumor size, location, and histological type did not show a significant impact on survival.
Conclusions:
- Early detection, curative resection feasibility, and extended lymphadenectomy are critical for improving survival in node-negative gastric cancer.
- These factors should guide patient stratification for adjuvant treatment strategies.
- Optimized lymphadenectomy techniques can enhance outcomes in gastric cancer management.
