[Radical surgical treatment of gastric cancer. Personal experience]

Abstract

After surgical therapy the survival outcome of gastric cancer is still poor. Early diagnosis and radical surgery are the two most important means to improve the prognosis. Radical surgery must include all lymph nodes embryologically related to stomach. The aim of this study was to verify whether an aggressive surgical strategy can increase postoperative survival rate. In the period 1990-1994 eighty two patients with gastric cancer were operated on. The M:F ratio was 1.6:1 and the mean age was 65.3 years (range 23-89). Palliative operations (6 gastroenterostomy) were performed in 7.3% of cases. In the other patients, 36 total gastrectomies (43.9%), 8 total gastrectomies extended to spleen, pancreas and colon (9.7%), 32 distal subtotal gastrectomies (39.1%) were performed. Gastric exeresis was always associated with lymph node dissection extended to level I and II (R2). In some cases level III and IV lymphadenectomy (R3) was performed according to Maruyama-Mishima technique. There were no intraoperative deaths. The operative mortality was 13.6% for total gastrectomies and 3.1% for subtotal gastrectomies. Postoperative complications occurred in 15.9% of total gastrectomies (3 anastomotic fistula, 2 wound infection, 1 subphrenic abscess, 1 melena) and in 3.1% of subtotal gastrectomies (1 sepsis). Stage III and IV cancers represented 74.4% of all cases (stage IIIA 19.6%, IIIB 21.9%, IV 32.9%). Metastatic lymph node involvement (N2+) affected 53.1% of T3 and 88.2% of T4 cancers. The mean survival rate of patients subjected to gastroenterostomy was 6 months. The 2-year survival for total gastrectomies was 42%, for subtotal gastrectomies 28.1%. In our experience, wide removal of lymph nodes and total or extended gastrectomies were performed without any increase of mortality and morbidity. In advanced stages, a wider exeresis increased survival and prevented local recurrence.
