Background and aims
This study aims to assess the tumour-related factors that influence long-term survival after curative gastrectomy with standard D1 lymphadenectomy for patients with stomach cancer.
Patients and methods
Patients who had undergone curative gastrectomy for carcinoma of the stomach at North Shore Hospital between 1990 and 2000 were identified from theatre records and the hospital database. Medical records were reviewed and included tumour location, type of operation, in-hospital mortality, gross morphology of tumour, histological type, and Helicobacter status; pathology slides were reviewed, and tumours were staged according to the new TNM staging. Patients were followed-up for 2–11 years. Length of survival was obtained for each patient from medical records or from family doctors.
Results
R0 gastrectomy was performed on 70 patients; median survival was 23 months, and all patients with early gastric cancer are currently still alive. T stage, nodal stage and histological type correlated significantly with survival, but multivariate analysis showed that T stage is the most significant predictor. Five-year survival was 26%. Significant survival difference was seen between T2a and T2b.
Conclusion
Histological subtype, lymph node metastases and depth of invasion are factors that affect survival of patients with gastric cancer; however, depth of invasion is more important than other variables. Tumour location and type of gastrectomy has no effect on survival. The latest TNM classification (sixth edition) gives a better prognostication than the previous classification.
