HEALTH RELATED QUALITY OF LIFE ASSESSMENT AFTER RADICAL PROSTATECTOMY IN MEN WITH PROSTATE SPECIFIC ANTIGEN ONLY RECURRENCE

Abstract

The health related quality of life assessment is becoming increasingly important among patients with prostate cancer. Meanwhile, treatment of patients with increasing prostate specific antigen (PSA) after radical retropubic prostatectomy remains controversial. We attempt to define the impact of PSA recurrence on the health related quality of life of patients after radical retropubic prostatectomy. Of 604 consecutive patients who underwent radical retropubic prostatectomy between March 1991 and September 1998, 510 (84%) were available for followup. Each patient was mailed the RAND 36-Item Health Survey and University of California, Los Angeles, Prostate Cancer Index questionnaire. A total of 348 (70%) questionnaires were returned. Health related quality of life scores were then compared between patients with and without PSA recurrence. A multivariate analysis was also performed to elucidate further the cause of differences between the groups. Overall, 88 (25%) patients had PSA recurrence. In regard to health related quality of life there were small (less than 10%) but statistically significant differences in 2 of 4 physical health domains (RAND 36-Item Health Survey). There was a significant decrease in only 1 category of the mental health domain for patients with PSA recurrence. Only sexual function was statistically lower on the University of California, Los Angeles, Prostate Cancer Index. This result reflects the lower incidence of nerve sparing in these patients, as confirmed by the multivariate analysis. Overall patient satisfaction was similar between those with and without PSA recurrence (76% and 79%, respectively). Our study demonstrates small health related quality of life differences in patients with biochemical PSA recurrence versus those without. These findings provide a baseline assessment of general and disease specific health related quality of life domains among these patients. Future studies should focus on differences in the measure of cancer anxiety before and after administration of adjuvant therapy in these asymptomatic patients.
