Background: Posttreatment surveillance affects millions of cancer survivors, but empiric data to guide clinical practice are lacking. This study assessed whether the intensity of surveillance testing after radical prostatectomy or radiation therapy for localized prostate cancer is associated with overall survival., Methods: Men diagnosed with localized prostate cancer between 2005 and 2010 who underwent radical prostatectomy or radiation therapy at a Commission on Cancer-accredited facility were randomly sampled. Primary data collected from 10 147 patients sampled across 1007 facilities were linked with existing data from the National Cancer Database. Analysis examined whether intensity of surveillance measured as the number of prostate-specific antigen (PSA) tests in the first year after primary treatment (categorized as 0-1 [low intensity], 2 [medium], or ≥3 [high intensity] PSA tests) was associated with overall survival. Secondary outcomes included recurrence-free survival (RFS) and subsequent use of imaging tests, biopsy procedures, and salvage treatment., Results: Median follow-up exceeded 8 years from prostate cancer diagnosis. Overall survival was not statistically significantly different across surveillance intensity groups among radiation therapy (P = .59) or radical prostatectomy (P = .29) patients. RFS was not statistically significantly different across surveillance intensity groups for radiation therapy (P = .13) patients but was for radical prostatectomy (P = .01) patients with high intensity associated with the worst RFS. In both treatments, higher surveillance intensity was associated with more procedures and salvage treatments., Conclusions: In patients with localized prostate cancer, more frequent PSA surveillance testing after radical prostatectomy or radiation therapy was associated with increased procedures and salvage treatments but not overall survival., (© The Author(s) 2024.

Objective: To assess the effect of a practice-level preoperative frailty screening and optimization toolkit (OPTI-Surg) on postoperative functional recovery and complications in elderly cancer patients undergoing major surgery., Background: Frailty is common in older adults. It increases the risk of poor postoperative functional recovery and complications. The potential for a practice-level screening/optimization intervention to improve outcomes is unknown., Methods: Thoracic, gastrointestinal, and urologic oncological surgery practices within the National Cancer Institute Community Oncology Research Program (NCORP) were randomized 1:1:1 to usual care (UC), OPTI-Surg, or OPTI-Surg with an implementation coach. OPTI-Surg consisted of the Edmonton Frail Scale and guided recommendations for referral interventions. Patients 70 years old or above undergoing curative intent surgery were eligible. The primary outcome was 8 weeks postoperative function (kcal/wk). The key secondary outcome was complications within 90 days. Mixed models were used to compare UC to the 2 OPTI-Surg arms combined., Results: From July 2019 to September 2022, 325 patients were enrolled in 29 practices. One hundred ninety-nine (64 UC, 135 OPTI-Surg) and 279 (78 UC, 201 OPTI-Surg) were evaluable for primary and secondary analysis, respectively. UC and OPTI-Surg patients did not significantly differ in total caloric expenditure (2.2 UC, 2.0 OPTI-Surg) after adjusting for baseline function ( P =0.53). UC and OPTI-Surg patients did not significantly differ in postoperative complications (25.6% UC, 35.3% OPTI-Surg, P =0.5)., Conclusions: Frailty assessment was successfully performed, but the OPTI-Surg intervention did not improve postoperative function nor reduce postoperative complications compared with UC. Future analysis will explore practice-level factors associated with toolkit implementation and the differences between the coaching and noncoaching arms., Competing Interests: E.F. is a founding shareholder of Ooney.
