Total gastrectomy is not necessary for proximal gastric cancer

Abstract

Background: Although there is an increasing incidence of proximal gastric cancers in the United States, the appropriate extent of resection for proximal gastric cancer is not known. This study addresses whether the type of operation (total gastrectomy [TG] vs proximal gastrectomy [PG]) affects outcome for proximal gastric adenocarcinoma.

Methods: Review of the prospective gastric database at Memorial Sloan-Kettering Cancer Center from July 1985 to August 1995 identified 391 patients with proximal gastric cancer. Of those patients, 98 underwent curative TG or PG through an exclusively abdominal approach. Patients undergoing esophagogastrectomy (n = 293) were excluded from analysis. Data are expressed as medians and ranges.

Results: The length of hospital stay was the same for patients undergoing resection for PG (16.5 days [range 8 to 55]) and for TG (18 days [range 8 to 48]). In addition, hospital mortality rates for PG (6.0%) were similar to those for TG (3.0%). There was no significant difference in tumor differentiation and overall stage between the groups that underwent TG and those that underwent PG. There was no significant difference in time to recurrence between the two operative groups (PG, 15.7 months, versus TG, 18 months). In addition, there was no association between first site of recurrence and type of procedure. The overall 5-year survival rate for proximal gastric cancer was 43% (median survival 46 months), whereas the 5-year survival rate for TG was 41% (median survival 51 months; difference not significant).

Conclusions: The extent of resection for proximal gastric cancer does not affect long-term outcome. TG and PG have similar overall survival rates and time and rate of recurrence, and both procedures can be accomplished safely.
