Survival after cancer surgery of elderly patients in New Mexico, 1969-1982.

To examine the effects of advancing age, sex, and ethnicity on estimated 30-day survival after surgery for cancer, we reviewed population-based data on 16,130 cancer cases collected by the New Mexico Tumor Registry from 1969-1982. For surgery at most sites, mortality increased with increasing age. The highest mortality was observed for sites requiring laparotomy or thoracotomy. Sex and ethnicity (Hispanic versus non-Hispanic white) had little effect on short-term survival. Comparison of short-term survival for two time periods, 1969-1975 and 1976-1982, showed a strong trend of improving survival for many sites.
