Patient-perceived Causes of Prostate Cancer: Result of an Internet-based Survey.

OBJECTIVE

To assess patients' perceived causes of prostate cancer (PCa) and relation to treatment satisfaction, an Internet-based survey study was designed. PCa is a profoundly personal disease, considering the location and common sequelae of treatment. Deeply held patient self-perceptions regarding the etiology of a patient's PCa may generate lasting beliefs that impact satisfaction with treatment selection.

MATERIALS AND

METHODS

Third-party web-based surveys were sent to patients receiving radical prostatectomy for clinically localized PCa. Patients were queried regarding demographic characteristics, family history, socioeconomic status, sexual function, urinary control, and factors believed to cause their PCa.

RESULTS

Among respondents (293 of 524, 55.9%), 237 (81.5%) provided primary causes for PCa. Evidence-based answers were provided by 128 (53.5%) patients, whereas a wide range of non-evidence-based responses were provided by 49 (20.5%) patients. Forty patients (16.7%) were undecided, and 20 (8.3%) offered belief-based responses. Evidence-based responses were more common in patients with a family history of PCa (P <.01); however, no significant differences were seen among race, educational level, or income. Patients providing an evidence-based cause of PCa were more likely to be potent (P <.01). Providing a non-evidence-based cause for PCa was associated with considering surgery as a wrong decision in treatment selection.

CONCLUSION

Among men with localized PCa, there is a wide spectrum of patient beliefs regarding the etiology of their disease that may reflect background and information sources. Further research is warranted to determine whether patient counseling should incorporate these considerations.
