The 21 % increase in penile cancer incidence in England since the 1970s may be explained by changes in sexual practice, greater exposure to sexually transmitted oncogenic human papilloma viruses, and decreasing rates of childhood circumcision. Improvement in survival is likely due to advances in diagnostic, staging and surgical techniques. There is a need for public health education and potential preventative strategies to address the increasing incidence.

Background There is no effective intravesical second-line therapy for non-muscle invasive bladder cancer (NMIBC) when bacillus Calmette-Guérin (BCG) fails. Objective To compare disease-free survival time (DFS) between radiofrequency-induced thermo-chemotherapy effect (RITE) and institutional standard second-line therapy (control) in NMIBC patients with recurrence following induction/ maintenance BCG. Design, settings, and participants Open-label, phase III randomised controlled trial accrued across 14 centres between May 2010 and July 2013 [HYMN (ClinicalTrials.gov: NCT01094964)].

Purpose Mesothelioma of the tunica vaginalis testis (MTVT) is a rare tumor, and currently, there are no published treatment recommendations. Methods We performed a systematic literature review and synthesized clinical presentation, clinicopathological factors associated with metastatic disease, treatment options, and outcomes in men with MTVT. Results We included 170 publications providing data on 275 patients. Metastatic disease occurred in 84/275 (31%) men with malignant MTVT: Most common sites included retroperitoneal lymph nodes (LNs) (40/84, 48%), lungs (30/84, 36%), and inguinal LNs (23/84, 27%). Invasion of the spermatic cord or scrotum was the only risk factor for local recurrence [odds ratio (OR) 3.21, 95% confidence interval (CI) 1.36–7.57]. Metastatic disease was associated with age ≥ 42 years (OR 3.02, 95% CI 1.33–6.86), tumor size ≥ 49 mm (OR 6.17, 95% CI 1.84–20.74), presence of necrosis (OR 8.31, 95% CI 1.58–43.62), high mitotic index (OR 13.36, 95% CI 1.53–116.51) or angiolymphatic invasion (OR 3.75, 95% CI 1.02–13.80), and local recurrence (OR 4.35, 95% CI 2.00–9.44). Complete remission in the metastatic setting was observed in five patients, most of whom were treated with multimodal therapy. Median survival in patients with metastatic disease was 18 months (IQR 7–43). Conclusion Malignant MTVT is a rare but aggressive disease. Since local recurrence is a risk factor for metastatic progression, we recommend aggressive local treatment. Survival and response to any treatment in the metastatic setting are limited.

To identify predictive pathological factors for local recurrence (LR) and to study the impact of LR on survival in patients treated with glansectomy for penile squamous cell carcinoma (pSCC). Patients and MethodsWe retrospectively studied patients treated with glansectomy at international, high-volume reference centres. We analysed histopathological predictors of LR, stratified patients into risk groups based on the number of risk factors present, and studied the impact of LR on survival outcomes using Kaplan-Meier survival analysis and stepwise Cox proportional hazards regression models. Subsequently, we performed sensitivity analyses excluding margin-positive cases, pT3 disease, and cN+ disease, or all of these factors. ResultsAcross nine institutions, 897 patients were included, of whom 94 experienced LR. On multivariable analysis, presence of high-grade disease and pT3 stage were independent predictors of LR. LR-free survival rates significantly differed according to the number of risk factors present, with a hazard ratio (HR) of 1.90 (95% confidence interval [CI] 1.17-3.07; P = 0.01) for the intermediate-risk group (one risk factor) and 6.11 (95% CI 3.47-10.77; P < 0.001) for the high-risk group (two risk factors), using the low-risk group (no risk factors) as reference. Patients who experienced LR had significantly worse overall survival (OS; HR 2.89, 95% CI 2.02-4.14; P < 0.001) and cancer-specific survival (CSS; HR 5.64, 95% CI 3.45-9.22; P < 0.001). LR (HR 3.82, 95% CI 2.14-6.8; P < 0.001), lymphovascular invasion and cN status were significant predictors of decreased CSS. LR remained a strong predictor of both OS and CSS in all sensitivity analyses. ConclusionsPathological T3 stage and presence of high-grade disease were independent histopathological predictors of LR after glansectomy for primary pSCC, which allowed risk stratification into three groups with significantly different risk of developing LR. Additionally, LR is related to poor OS and CSS, indicating that LR is a manifestation of underlying aggressive disease and clearly challenging the dogma of using organ-sparing surgery whenever possible since survival is unaffected by higher LR rates.
