49 Background: RP, EBRT, and PI for the treatment of clinically localized prostate cancer may negatively impact urinary continence. Predictions of treatment-related urinary problems from patient-reported, prospective data may be useful in treatment decision-making. Methods: Patient-reported data on treatment-related urinary incontinence was obtained from four prospective, longitudinal, health-related quality-of-life (HRQOL) protocols comprising 2,668 patients treated between 1999 and 2011 by RP (n = 1,294), EBRT (n = 630), and PI (n = 744). A single HRQOL instrument was not uniformly used for each study, although questions pertaining to the quantity (pad use) and frequency of urinary incontinence (“never” to “more than once per day”) were identical among the studies. Patient responses were obtained at baseline and at two years after treatment. The endpoint of the model was urinary continence defined as no pad use and leakage of urine less than once per day. Cox proportional hazards regression analysis was used to model the clinical information and follow-up data. Internal validation was performed using bootstrapping. Results: Overall, 1,937 (92%) of patients with complete data available were considered to be continent at baseline. Significant differences in baseline characteristics such as patient age, ethnicity, and disease severity existed between the treatment groups. The overall continence rate at two years was 66%, 88%, and 87% for patients treated by RP, EBRT, and PI, respectively (p < 0.001). In multivariable analysis, age (p = 0.001), baseline frequency of incontinence (p < 0.001), EBRT (p < 0.001), PI (p < 0.001), and ethnicity (p < 0.001) were associated with urinary continence. A nomogram based on the predictive parameters had a concordance index of 0.74 and predictions were well-calibrated with observed outcome. Conclusions: An externally-validated nomogram that predicts two-year urinary continence after treatment for localized prostate cancer has been developed and will be useful for patient counseling regarding treatment options.

55 Background: RP, EBRT, and PI for treatment of clinically localized prostate cancer may negatively impact bowel function. Predictions of treatment-related bowel problems from patient-reported, prospective data may be useful in treatment decision-making. Methods: Patient-reported data on treatment-related bowel problems was obtained from 4 prospective, longitudinal, health-related quality-of-life (HRQOL) protocols comprising 2,668 patients treated between 1999 and 2011 by RP (n=1294), EBRT (n=630), and PI (n=744). A single HRQOL instrument was not uniformly used for each study, though all patients were asked if they experienced bother related to bowel problems using a similar 5-point scale. Patient responses were obtained at baseline and at 2 years after treatment. The endpoint of the model was bowel dysfunction, defined as bowel symptoms that were identified as a moderate-to-big problem. Cox proportional hazards regression analysis was used to model the clinical information and follow-up data. Internal validation was performed using bootstrapping. Results: Significant differences in baseline characteristics such as patient age, ethnicity, and disease severity existed between the treatment groups. Overall, 46 patients (2%) with complete data available had bowel dysfunction at baseline, including 11 (1%), 19 (4%), and 16 (3%) patients treated by RP, EBRT, and PI, respectively (p = 0.001). The overall rate of bowel dysfunction at 2 years in those patients with no bowel dysfunction at baseline was 2%, 10%, and 4% for patients treated by RP, EBRT, and PI, respectively (p < 0.001). In multivariable analysis, EBRT (p < 0.001), PI (p < 0.001), baseline bowel symptoms (p < 0.001), and institution (p = 0.04) were associated with bowel dysfunction. A nomogram based on the predictive parameters had a concordance index of 0.73 and predictions were well-calibrated with observed outcome. Conclusions: An externally validated nomogram that predicts 2-year incidence of bowel dysfunction after treatment for localized prostate cancer has been developed and may be useful for patient counseling regarding treatment options.

51 Background: RP, EBRT, and PI for the treatment of clinically localized prostate cancer may negatively impact sexual function. Predictions of treatment-related sexual problems from patient-reported, prospective data may be useful in decision-making. Methods: Patient-reported data on treatment-related sexual problems was obtained from 4 prospective, longitudinal, health-related quality-of-life (HRQOL) protocols comprising 2,668 patients treated between 1999 and 2011 by RP (n = 1,294), EBRT (n = 630), and PI (n = 744). A single HRQOL instrument was not uniformly used for each study, although questions pertaining to the quality and frequency of erections were identical among the studies. Only those patients with quality of erections sufficient for intercourse were included in the model. The endpoint of the model was erections suitable for intercourse on at least half of attempts at 2 years after treatment, with or without the use of oral medications. Cox proportional hazards regression analysis was used to model the clinical information and follow-up data. Internal validation was performed using bootstrapping. Results: Overall, 931 (74%), 249 (42%), and 323 (45%) patients treated by RP, EBRT, and PI were considered to be potent at baseline. Significant differences in baseline characteristics such as patient age, ethnicity, and disease severity existed between the treatment groups. The potency rate at 2 years for 1,215 patients who were potent at baseline and had complete follow-up data was 38%, 51%, and 61% for patients treated by RP, EBRT, and PI, respectively (p < 0.001). In multivariable analysis, age (p < 0.001), baseline frequency of erections (p < 0.001), EBRT (p < 0.001), PI (p < 0.001), PSA (p = 0.001), and institution (p = 0.006), were associated with potency. A nomogram based on the predictive parameters had a concordance index of 0.72 and predictions were well-calibrated with observed outcome. Conclusions: An externally-validated nomogram that predicts 2-year potency after treatment for localized prostate cancer has been developed and may be useful for patient counseling regarding treatment options.

32 Background: Radical prostatectomy (RP), external beam radiotherapy (EBRT), and brachytherapy are commonly utilized treatments for localized prostate cancer and may negatively impact sexual function to varying degrees. Patient-, disease-, and treatment-specific factors may all impact post-treatment sexual function. We aimed to evaluate predictors of post-treatment impotency, and develop a prognostic nomogram using prospective, patient-reported data from multiple validated health-related quality-of-life (HRQOL) instruments. Methods: Between 1999 and 2011, patient-reported data regarding treatment-related effects on erectile function were obtained from 2668 patients enrolled in one of four prospective longitudinal HRQOL protocols from the United States and Spain. Patients were treated with RP (n=1,294), EBRT (n=630), or brachytherapy (n=744). Although different HRQOL instruments were used in each protocol, questions pertaining to quality and frequency of erections were identical across the different instruments. Patient responses were obtained at baseline and 2 years after treatment. The endpoint of the model was impotency at 2 years post-treatment. Logistic regression analysis was used to model clinical information and outcome data. Internal validation was performed using bootstrapping. Results: 1,306 patients were potent at baseline and had 24-month follow-up. Differences in baseline patient characteristics such as patient age, ethnicity, and disease severity existed between the treatment groups. The impotency rate at 2 years was 62%, 53%, and 41% for patients treated by RP, EBRT, and brachytherapy, respectively. In multivariable analysis, age, PSA, modality of treatment, frequency of preoperative erections, diabetes, and hypertension were associated with post-treatment impotency (all p<0.05). A nomogram based on the predictive parameters had a concordance index of 0.726 and predictions were well-calibrated with observed outcome. Conclusions: A validated nomogram that predicts 2-year risk of impotency after treatment of localized prostate cancer has been developed and is anticipated to be useful for patient counseling regarding treatment options.

4507 Background: Although patient-reported treatment outcomes have gained wide acceptance, numerical changes in validated instruments are difficult to interpret by patients and physicians. Using functional categories derived from numerical scales, we report 24- and 36-month outcomes after treatments for localized prostate cancer, presented by patients’ baseline (pre-treatment) functional status, to provide more useful prognostic information and to identify further changes in the third year after treatment. Methods: Using validated symptom indices, we prospectively measured sexual, urinary, and bowel functions of 438 men at baseline, and at fixed intervals post treatment. We translated numerical scores into functional categories: good (normal), intermediate, and poor (severe dysfunction). Results: Abnormal baseline function and surgery in men with normal function uniformly produced poor sexual function ( table ), and more external beam radiotherapy (EBRT) and brachytherapy (BT) patients deteriorated between 24 and 36 months. For those with normal urinary continence, NNSRP (non-nerve sparing radical prostatectomy) produced poor outcomes (26%) more frequently than NSRP (9%) at 24 months and 36 months, despite improvement in some NNSRP patients. Severe incontinence was rare after EBRT (1%) and BT (3%), though slightly more frequent in EBRT patients by 36 months. For patients with normal bowel function, EBRT and BT caused worse outcomes than RP; no change occurred after 24 months. Conclusions: Abnormal baseline sexual function and surgery produced uniformly poor sexual function outcomes and poor function increased significantly between 24 and 36 months after radiation therapy. Significant changes in functional category occurred despite unchanged average numerical scores, indicating that stable numerical indices may conceal significant functional changes.

Abstract Purpose: To evaluate urinary continence and sexual potency following radical prostatectomy and adjuvant radiotherapy. Materials/Methods: Expanded Prostate Cancer Index Composite (EPIC) surveys of patients with localized prostate cancer treated with surgery followed by adjuvant/salvage pelvic radiotherapy (S+RT) were analyzed. A control cohort was primary radiotherapy (RT). Results: Surveys at least 1 year after treatment were available for 130 S+RT and 374 RT patients. For S+RT vs. RT, the mean urinary incontinence score was 68 [6.25 -100] versus 86.4 [CI-95 39.5-100] (p<0.001), confirming 6.5 points of clinically significant difference. The adjusted odds ratio for superior urinary function was 2.67 (1.7-4.1, p<0.001) for primary radiotherapy. The odds ratio of having both poor urinary and sexual performance was 0.29 in RT arm (0.14-0.58, p<0.001) when adjusted to age and ADT use, group risk stratification, co morbidities and smoking status. Conclusion: In this cross sectional study, Surgery with adjuvant/salvage RT was associated with significantly worse patient reported urinary continence outcomes at 1-year post treatment, lower odds of achieving perfect urinary continence and a threefold risk of reverse ‘bifecta’ with inferior urinary continence and sexual performance. Longitudinal studies of evolving toxicity are required to validate these findings.

Abstract Purpose: To evaluate urinary continence and sexual potency following radical prostatectomy and adjuvant radiotherapy.Materials/Methods: Expanded Prostate Cancer Index Composite (EPIC) surveys of patients with localized prostate cancer treated with surgery followed by adjuvant/salvage pelvic radiotherapy (S+RT) were analyzed. A control cohort was primary radiotherapy (RT). Reverse "bifecta" was defined as a score less than 60 in both incontinence and sexual domains. Superior urinary function was defined as a score above 90. The clinically important difference was calculated using a distribution approach.Results: Surveys at least 1 year after treatment were available for 130 S+RT and 374 RT patients. For S+RT vs. RT, the mean urinary incontinence score was 68 [6.25 -100] versus 86.4 [CI-95 39.5-100] (p<0.001), confirming 6.5 points of clinically significant difference. The adjusted odds ratio for superior urinary function was 2.67 (1.7-4.1, p<0.001) for primary radiotherapy. The odds ratio of having both poor urinary and sexual performance (reverse " bifecta") was 0.29 in RT arm (0.14-0.58, p<0.001) when adjusted for age and Androgen Deprivation Therapy (ADT) , group risk stratification, comorbidities and smoking status.Conclusion: In this cross sectional study, Surgery with adjuvant/salvage RT was associated with significantly worse patient reported urinary continence outcomes at 1-year post treatment, lower odds of achieving perfect urinary continence and a threefold risk of reverse ‘bifecta’ with inferior urinary continence and sexual performance. Longitudinal studies of evolving toxicity are required to validate these findings. Patients referred for surgery with a high probability of requiring adjuvant or salvage radiotherapy should be informed regarding the potential composite toxicity of both surgery and radiotherapy.

PURPOSE To assess complications of therapy for early (nonmetastatic) prostate cancer. PATIENTS AND METHODS A prospective study of a cohort of 279 men who sought treatment advice and completed required pretreatment forms. The measures were self-reported patient symptoms and other measures of quality of life before therapy and at 3 and 12 months afterward. RESULTS Bowel and bladder symptoms were uncommon pretreatment. Patients frequently reported irritative bowel and bladder symptoms at 3 months after radiotherapy, although these subsided somewhat at 12 months. Substantial ("a lot") urinary incontinence and wearing of absorptive pads were reported by 11% and 35% at 12 months after surgery and varied little by age. Incontinence occurred after radiotherapy infrequently, and only in men more than 65 years old. Inadequate erections, present in one third of men pretreatment, were nearly universal at 3 months after surgery, although some improvement, primarily in men under 65 years of age, was evident at 12 months. Sexual dysfunction after radiotherapy increased less but continually through 12 months, suggesting that observed treatment-related differences would decline with further follow-up. CONCLUSION External-beam radiotherapy of early prostate cancer is followed by bowel and bladder irritability, by increasingly severe sexual dysfunction and, in men aged more than 65 years, occasional urinary incontinence. Greater sexual dysfunction and urinary incontinence occur in the year following radical prostatectomy. These postsurgical complication rates from patient questionnaires are greater than have been reported in other treatment series and confirm the results of two retrospective studies of patient-reported complications.
