57 Background: Cardiovascular disease (CVD) is the leading non-cancer cause of death among men with prostate cancer (PC), particularly during androgen-deprivation therapy. While CVD risk-prediction models are well established in the general population, barriers to integration within oncology workflows remain poorly defined. Guided by the PRISM and RE-AIM frameworks, this study evaluated multilevel determinants influencing adoption, feasibility, and sustainability of CVD risk-assessment tools in PC care. Methods: A national, cross-sectional survey of 45 physicians (medical oncology 49%, urology 38%, radiation oncology 13%) from 18 U.S. states was conducted. Respondents represented early- (27%), mid- (36%), and late-career (38%) clinicians across academic (87%) and community (13%) settings. Quantitative items mapped to PRISM/RE-AIM domains assessed adaptability, cost/resource feasibility, effectiveness, equity, and sustainability; open-ended responses explored contextual barriers and facilitators. Descriptive statistics summarized quantitative data. Results: Physicians reported moderate-to-high readiness to adopt a CVD risk-assessment tool, emphasizing workflow alignment and EHR integration over algorithmic complexity. Table 1 summarizes domain-specific findings. Ninety-three percent of respondents favored lab-independent models that minimize workflow disruption. Conclusions: Pre-implementation analysis highlighted that structural barriers, rather than algorithmic or statistical limitations, remain the primary obstacles to adopting CVD risk-assessment tools in prostate-cancer care. Physicians emphasized the need for EHR-integrated, non-laboratory-based, and time-efficient tools that align with routine oncology workflows and minimize cross-specialty friction. Addressing these practical and organizational determinants may be pivotal to achieving equitable, scalable, and sustainable cardio-oncology implementation across diverse practice settings.

Abstract Introduction This study investigated the efficacy and safety of neoadjuvant chemotherapy for locally advance penile squamous cell carcinoma for which current evidence is lacking. Methods Included patients had locally advanced penile squamous cell carcinoma with clinical lymph node metastasis treated with at least 1 dose of neoadjuvant chemotherapy prior to planned consolidative lymphadenectomy. Objective response rates were assessed using Response Evaluation Criteria in Solid Tumors v1.1. The primary and secondary outcomes were overall survival and progression-free survival, estimated by the Kaplan–Meier method. Treatment-related adverse events were graded per the Common Terminology Criteria for Adverse Events v5.0. Results A total of 209 patients received neoadjuvant chemotherapy for locally advanced and clinically node-positive penile squamous cell carcinoma. The study population consisted of 7% of patients with stage II disease, 48% with stage III, and 45% with stage IV. Grade 2 treatment-related adverse events occurred in 35 (17%) patients, and no treatment-related mortality was observed. Of the patients, 201 (97%) completed planned consolidative lymphadenectomy. During follow-up, 106 (52.7%) patients expired, with a median overall survival of 37.0 months (95% confidence interval [CI] = 23.8 to 50.1 months) and median progression-free survival of 26.0 months (95% CI = 11.7 to 40.2 months). Objective response rate was 57.2%, with 87 (43.2%) having partial response and 28 (13.9%) having a complete response. Patients with objective response to neoadjuvant chemotherapy had a longer median overall survival (73.0 vs 17.0 months, P < .01) compared with those who did not. The lymph node pathologic complete response rate was 24.8% in the cohort. Conclusion Neoadjuvant chemotherapy with lymphadenectomy for locally advanced penile squamous cell carcinoma is well tolerated and active to reduce the disease burden and improve long-term survival outcomes.

9 Background: The efficacy of neoadjuvant platinum-based chemotherapy (NAPC) in penile squamous cell carcinoma (PSCC) was provided by small clinical trials, leaving clinicians with scant evidence-based guidance. Thus, we aimed to analyze real-world outcomes of patients with PSCC who received NAPC prior to surgical resection. Methods: Patients from 9 tertiary care centers who had undergone NAPC prior surgical resection for PSCC were included with locally advanced (cTany, cN+), non-metastatic (M0) disease. The primary and secondary outcomes were overall survival (OS) and progression-free survival (PFS), Response was determined via best overall response measured with RECIST 1.1 criteria. Results: 167 patients were included, 137 (84%), of which received TIP prior to surgical resection. Ninety-two (55%) patients died during follow up, and the mean follow up for survivors was 57 months. The median OS was 42 months, while the median PFS was 17 months. The table details the response rates to NAPC, the associated survival, and Cox Proportional Hazards Modelling of OS and PFS. Predictors for OS and RFS included lymphovascular invasion, positive number of lymph nodes, extranodal extension, downstaging, best overall response, and ypN status. Figure 1 demonstrates OS outcomes by RECIST best response after chemotherapy, presence of downstaging after NAPC, ypN stage, and presence of extranodal extension. Conclusions: Upfront NAPC is effective in patients with lymph node metastases from penile carcinoma. Unsurprisingly, patients who demonstrated a robust response to therapy had improved survival outcomes compared to those who had not—as measured by RECIST criteria, tumor downstaging, pN staging, and presence of extranodal extension. This study represents the largest conglomeration of multi-institutional penile carcinoma patients treated with NAPC, and provides further supportive data for multimodal therapy for advanced penile cancer patients while prospective clinical trials complete accrual.

The NCCN Guidelines for Prostate Cancer Early Detection provide recommendations for individuals with a prostate who opt to participate in an early detection program after receiving the appropriate counseling on the pros and cons. These NCCN Guidelines Insights provide a summary of recent updates to the NCCN Guidelines with regard to the testing protocol, use of multiparametric MRI, and management of negative biopsy results to optimize the detection of clinically significant prostate cancer and minimize the detection of indolent disease.
