Mobile Audio Recording Technology to Promote Informed Decision Making in Advanced Prostate Cancer.

PURPOSE: Men with metastatic castration-resistant prostate cancer increasingly encounter complex treatment decisions. Consultation audio recordings and summaries promote patient informed decision making but are underutilized. Mobile recording software applications may increase access. Little is known regarding the feasibility of implementation in clinical encounters. METHODS: We conducted a mixed-methods pilot study in men with progressive metastatic castration-resistant prostate cancer. We instructed patients to use a mobile software application to record an oncology visit. Patients could share the recording with our patient scribing program to receive a written summary. We assessed feasibility and acceptability with postvisit surveys. We measured patient-reported helpfulness of the intervention in decision making and change in Decisional Conflict Scale-informed subscale. We conducted semistructured interviews to explore implementation and analyzed transcripts using thematic analysis. RESULTS: Across 20 patients, 18 (90%) recorded their visits. Thirteen of 18 (72%) listened to the recording, and 14 of 18 (78%) received a summary. Eighteen of 20 (90%) visits were telehealth. Fourteen patients (70% of all 20; 78% of 18 question respondents) found the application easy to use. Nine patients (50% of 18 recording patients; 90% of 10 question respondents) reported that the recording helped treatment decision making. Decisional conflict decreased from baseline to 1-week postvisit (47.4-28.5, P < .001). Interviews revealed benefits, facilitators, contextual factors, and technology and patient-related barriers to recordings and summaries. CONCLUSION: In this single-institution academic setting, a mobile application for patients to record consultations was a feasible, acceptable, and potentially valued intervention that improved decision making in the telehealth setting. Studies in larger, diverse populations are needed.

A multidisciplinary team-based approach with lifestyle modification and symptom management to address the impact of androgen deprivation therapy in prostate cancer: A randomized phase II study.

BACKGROUND: Androgen deprivation therapy (ADT) is associated with numerous toxicities that are potentially modifiable. We sought to evaluate the impact of participation in a multidisciplinary clinic, STAND (Supportive Therapy in Androgen Deprivation) Clinic, designed to provide individualized lifestyle modification and management of ADT-related side effects. METHODS: This phase II study recruited men with prostate cancer who had started ADT <6 months prior to enrollment, and in whom ADT was planned for at least 12 months following enrollment. Patients were randomized in a 1:1 ratio to either the STAND Clinic or usual care. Patients randomized to the STAND Clinic were provided monthly multidisciplinary assessment and counseling on exercise, nutrition, and symptom management for 12 months on a rotating schedule. Primary outcome was change from baseline to 12 months in percent body fat. Feasibility outcomes were also assessed by measuring percentage of completed visits. Secondary outcomes included change from baseline to 12 months in 3 domains: (1) metabolic impact and bone health, (2) quality of life (QOL), and (3) physical activity. RESULTS: A total of 25 men were randomized to STAND clinic, and 23 were randomized to usual care. The study did not meet its accrual target of 32 men in each arm and was closed early due to lack of financial support. Overall, 91% (295 of 325) of STAND clinic visits were completed. Eighteen out of the 25 patients in STAND clinic arm (72%) completed all 12 months of STAND clinic visits, and 80% (20 of 25) completed the first 6 months. For all primary and secondary outcomes, there were no statistically significant differences between treatment arms. CONCLUSION: Individualized and comprehensive management of ADT toxicities in a multidisciplinary clinic was well attended by patients. However, we did not find any differences in the outcomes assessed between the intervention arm and control.

Itraconazole as a Noncastrating Treatment for Biochemically Recurrent Prostate Cancer: A Phase 2 Study.

BACKGROUND: Patients with biochemically recurrent prostate cancer and short prostate-specific antigen doubling time (PSADT) are at risk for metastasis yet may wish to avoid androgen deprivation therapy. Itraconazole may have antitumor activity without affecting circulating androgen levels. We therefore evaluated itraconazole as a potentially noncastrating treatment approach in biochemically recurrent prostate cancer. PATIENTS AND METHODS: Patients with biochemically recurrent prostate cancer and PSADT ≤ 15 months, with serum testosterone > 150 ng/dL, were prospectively enrolled. The primary end point was the proportion of patients who experienced ≥ 50% decline from baseline in serum prostate-specific antigen (PSA) by week 12. RESULTS: Twenty-one patients were enrolled. The median (range) age, baseline PSA, and PSADT at study entry was 72 (49-76) years, 7.6 (1.5-45.5) ng/mL, and 5.7 (1.2-13.0) months, respectively. Among 19 patients with evaluable data, 1 patient (5%) had a > 50% PSA decline. Nine patients (47%) experienced any PSA decline (mean decline 25.0%, range 2%-60%) by week 12. Among 10 patients without a PSA decline, the on-treatment versus pretreatment PSADT was not significantly longer (median 6.8 vs. 4.3 months, P = .17). There was no significant change from baseline to week 12 in serum testosterone (median change = 32.4%, P = .21) or androstenedione (median change = -8.3%, P = .85). The most common adverse events were edema (52%), fatigue (38%), hypertension (24%), and hypokalemia (24%). CONCLUSION: Itraconazole modulates serum PSA levels without lowering serum testosterone. However, the magnitude of effect is modest, and treatment carries risk of toxicities associated with mineralocorticoid excess.
