Gastric cancer: an audit of 122 consecutive cases and the results of R1 gastrectomy.
In a consecutive series of 122 patients with gastric carcinoma, 9 per cent had no operation, 27 per cent had incurable disease at laparotomy, and 64 per cent underwent gastric resection. R1 gastrectomy was performed in 73 of the 78 resections. The operative mortality after gastric resection was 4 per cent, but there were no deaths after potentially curative resections. The actuarial 5-year survival was 20 per cent overall, 60 per cent in patients undergoing a 'curative' resection with N0 disease, and 18 per cent in patients with N1 disease. Local or regional recurrence without evidence of distant metastases was identified in 11 per cent of cases after 'curative' resections. The probability of survival was adversely affected by N1 nodal involvement (P less than 0.005) and by the presence of poorly differentiated or anaplastic tumours (P less than 0.001). Only 6 per cent of patients had early gastric cancer, and absolute curative resections by Japanese criteria were possible in only 5 per cent of cases. The results suggest that the unfavourable presenting pathology is the principal determinant of the poor prognosis of gastric cancer. A more radical or extended lymphadenectomy (R2/3 gastrectomy) might have cured more patients with N1 metastases, but only 12 per cent of potentially curable patients had N1 disease in this study, and it appears that more radical surgery may have little effect on the overall survival rates for gastric cancer.
