Cáncer gástrico: resultados quirúrgicos y sobrevida / Gastric cancer: surgical results and survival

ABSTRACT

From 1975 to 1984, 292 patients with gastric cancer were treated according to a prospective and standarized surgical protocol. This series included 195 men and 97 women, with an average age of sectable at laparotomy. Gastric ressection was performed in 173 (63,3%) (distal subtotal gastrectomy in 94 and total gastrectomy in 79). Operative mortlaity for subtotal gastrectomy was 3.1% and 6.3% for total gastrectomy. Early gastric cancer was found in 21 patients (none presented lymph node metastases). The cancer invaded the muscular layer in 18(31% with lymph node metastases) and reached beyond the muscular layer in 134 patients (60.8% with lymph node metastases). The five year actuarial survival was 0% in patients who did not undergo gastric resection, 35,5% for those patients with tumor invading the serosal layer or beyond who ressected, 56.5% for those with invasion up to the muscular layer and 91.8% for patients with early gastric cancer. For those patients who underwent a curative ressection, actuarial five year survival was 81%
