Abstract
(Purpose) Little is known regarding factors for decision-making on treatment by localized prostate cancer patients. We therefore conducted a survey series of cases for influence on treatment decision making, and also satisfaction after therapy.
(Materials and methods) A total of 51 patients with localized prostate cancer treated with radical prostatectomy (RP) or external beam radiation therapy (EBRT) were mailed original questionnaires about their treatment decision-making factors and satisfaction and the results compared between the two groups.
(Result) Some 48 (94.1%) patients responded to the questionnaire, 38 (79.2%) and 10 (20.8%) after RP and EBRT, respectively. The major factor determining the decision as to treatment approach was the physician in both groups (more than 90%). Excluding physicians, family or others were more important in the RP group than the EBRT group (p=0.023). RP group patients desired removal of their prostate for cancer control, while, EBRT group patients favored the less invasive approach in consideration of side effects. Over 80% patients indicated they would definitely or probably choose the same treatment again, although some of the RP group would switch to watchfulwaiting because of sexual dysfunction, urinary incontinence and the invasive nature of the procedure.
(Conclusion) Physicians are in a most important position to help patients understand prostate cancer and treatment, outcomes, and need to help them make their best choice, with appropriate follow up including mental care.
