Abstract

Background

As the U.S. population ages, an increasing number of elderly patients with gastric adenocarcinoma are being evaluated for surgical resection. This study aimed to describe the short- and long-term outcomes after gastric cancer resection for patients 80 years of age or older.

Methods

Patients who underwent gastrectomy for gastric adenocarcinoma from 2000 to 2012 at seven U.S. academic institutions were analyzed. The main outcome measures included postoperative morbidity, mortality, survival, and failure to rescue (defined as death after any complication).

Results

Of 953 patients who underwent distal or total gastrectomy during the 12-year study period, 127 (13 %) were 80 years of age or older. Although the type of postoperative complications did not differ between the two groups, octogenarians had a higher incidence of any (54 vs 41 %; p = 0.006) and of major (28 vs 17 %; p = 0.006) postoperative complications. This translated into higher 30-day (10.2 vs 3.6 %; p = 0.001) and 90-day mortality (19.7 vs 7.9 %; p = 0.001) rates, with correspondingly higher failure-to-rescue rates (17.4 vs 8 %; p = 0.015). However, disease-specific survival after resection was equivalent between the two groups (5-year survival: 46 vs 53 %; p = 0.676). In the multivariate analysis, age of 80 years or older, blood transfusion, and albumin and creatinine levels all were independent predictors of 90-day mortality. Stage, tumor grade, race, blood transfusion, and adjuvant therapy, but not age, were independently associated with disease-specific survival.

Conclusion

Perioperative mortality and failure-to-rescue from complications is substantial for octogenarians undergoing gastric cancer resection. However, if the operation can be performed safely, the long-term cancer-specific outcome appears similar to that for younger patients.
