Quality of life measurements do not support palliative pancreatic cancer treatments.

Although resection for pancreatic cancer is occasionally curative, its major value lies in restoring patients to a more normal life. The objective of this study was to evaluate the functional quality of life (QoL) of patients undergoing various treatments for pancreatic cancer using a nationwide, multi-institutional, non-referral patient population. From 822 pancreatic cancer patients treated from 1989 to 1995, and listed in the Department of Defense (DoD) hospital central computerized tumor registry, we selected 781 with evaluable survival information. Local tumor registrars had contacted patients at least yearly and prospectively compiled a QoL index using a self-reported Karnofsky performance status (KPS); values were obtained for patients alive in March of 1995 and/or 1996. Survival duration and KPS scores were then compared by stage and treatment using analysis of variance (F-test). Resection significantly increased KPS and mean survival time with stage I-II cancers and improved mean survival time, but not KPS, in patients with node positive (stage III) disease. The projected five-year survival rate after resection in stages I-II was 24% but zero for stage III. Patients receiving combined chemo- and radiation therapies, whether given as adjuvant or primary treatment, had significantly longer mean survival duration. However, KPS scores were not higher in treated patients. These data indicate that patients live longer and better lives after resection of localized pancreatic cancers, but QoL measurements do not support resection for pancreatic cancer involving lymph nodes. Unresected patients selected for combined chemo- and radiation therapy live longer, but not better, lives.
