Purpose: Penile cancer is rare, with significant morbidity and limited literature assessing utility of peripheral and deep en face margin assessment (PDEMA) vs traditional margin assessment (vertical sections) on treatment outcomes. Materials and Methods: This was a 32-year retrospective multicenter cohort study at 3 academic tertiary care centers. The cohort consisted of 189 patients with histologic diagnosis of in situ or T1a cutaneous squamous cell carcinoma of the penis at Brigham and Women's, Massachusetts General Hospital (1988-2020), and Memorial Sloan Kettering Cancer Center (1995-2020) treated with PDEMA surgical excision, excision/circumcision, or penectomy/glansectomy. Local recurrence, metastasis, and disease-specific death were assessed via multivariable Cox proportional hazard models. Results: The cohort consisted of 189 patients. Median age at diagnosis was 62 years. Median tumor diameter was 1.3 cm. The following outcomes of interest occurred: 30 local recurrences, 13 metastases, and 5 diseasespecific deaths. Primary tumors were excised with PDEMA (N = 30), excision/circumcision (N = 110), or penectomy/glansectomy (N = 49). Of patients treated with traditional margin assessment (non-PDEMA), 12% had narrow or positive margins. Five-year proportions were as follows with respect to local recurrence-free survival, metastasis-free survival, and disease-specific survival/progression-free survival, respectively: 100%, 100%, and 100% following PDEMA; 82%, 96%, and 99% following excision/circumcision; 83%, 91%, and 95% following penectomy/glansectomy. A limitation is that this multi-institutional cohort study was not externally validated. Conclusions: Initial results are encouraging that PDEMA surgical management effectively controls earlystage penile squamous cell carcinoma. [ABSTRACT FROM AUTHOR]

Introduction: Hyperthermic mitomycin (HM) is a novel treatment modality for selected patients with high-risk non-muscle invasive bladder cancer (NMIBC). We sought to determine predictors of response to this therapy. Patients and Methods: A longitudinal, cohort study of 97 patients with high-risk NMIBC treated with ≥4 HM instillations on a prophylactic schedule was conducted. The primary outcome was time-to-progression survival; secondary outcomes were overall survival, cancer-specific survival, and adverse events. Descriptive statistics, Kaplan-Meier survival analyses, Cox proportional hazards modelling, and univariate and multivariable regression were performed. Results: The presence of initial complete response (CR; no evidence of disease at first check video-cystoscopy and urine cytology) post-HM treatment was an independent predictor of good response to HM. Female patients and those without carcinoma in situ (CIS) also appeared to respond better to the intervention. The overall bladder preservation rate at a median of 27 months was 81.4%; 17/97 (17.5%) patients died during the course of the study. Conclusions: High-risk NMIBC patients can be safely treated with HM and have good oncological outcome. However, those without an initial CR have a poor prognosis and should be counselled towards adopting other treatment methodologies such as cystectomy. Female gender and lack of CIS may be good prognostic indicators for response to HM. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Purpose of Review: Prostate cancer remains the commonest nondermatological cause of cancer in Western men and the second leading cause of cancer death in these men. While low and intermediate-risk prostate cancers make up the vast bulk of prostate cancer diagnoses, it is high-risk prostate cancer that is a much larger killer. Management paradigms for such disease are changing and thus we review the current state of play with the management of these cancers and what the future might hold., Recent Findings: High-risk prostate cancer is a heterogeneous beast, with huge variations in disease severity. Hence, management of these cases must be tailored based on specific risk factors of individual patients, and the role for surgery especially in the lower end of the spectrum is increasing., Summary: The increasing use of radical extirpative surgery might negatively impact functional outcomes but are likely to prolong lives of high-risk prostate cancer sufferers, though more research from well conducted randomized controlled trials is needed to exactly define which patient subpopulations should receive which therapies, in which orders, and at what times.
