Penile cancer is a rare neoplasm representing less than 1% of all malignancies in the USA and Europe but is a significant public health hazard in the developing world. Male neonatal circumcision has been associated with a dramatic decrease in penile cancer rates with countries such as Israel, where circumcision is widely performed, having the lowest incidence in the world at <0.1% of malignancies. Many risk factors have been identified for penile cancer including phimosis, lack of circumcision, obesity, lichen sclerosis, chronic inflammation, smoking, UVA phototherapy, socioeconomic status, human papillomavirus (HPV) infection and immune compromised states. The relationship between these factors and invasive disease varies and continues to be investigated. Our objective was to present a contemporary overview of the epidemiology and risk factors for invasive penile cancer.
PURPOSE According to National Comprehensive Cancer Network guidelines, adjuvant chemotherapy (AC) has been advocated after primary retroperitoneal lymph node dissection (RPLND) to reduce the risk of relapse in pathologic nodal (pN) stage pN2 or pN3, whereas surveillance is preferred for pN1. We sought to explore the oncologic efficacy of primary RPLND alone for pathologic stage II in nonseminomatous germ cell tumors (NSGCTs) to reduce overtreatment with chemotherapy. METHODS Patients with pathologic stage II NSGCT after primary RPLND between 2007 and 2017 were identified. Patients were excluded for elevated preoperative serum tumor markers, receipt of AC, or if pure teratoma or primitive neuroectodermal tumor elements were found in the retroperitoneal pathology. RESULTS We identified 117 patients with active NSGCT in the retroperitoneum after primary RPLND. We excluded seven patients who lacked meaningful follow-up and 13 patients who received AC. There were 97 patients treated with RPLND alone: 41 pN1, 46 pN2, and 10 pN3. In total, 77 of 97 patients had not recurred after a median follow-up time of 52 months. The 2-year recurrence-free survival (RFS) was 80.3%, and the 5-year RFS was 79%. No differences in RFS were noted among nodal stage—pN1, pN2, and pN3—on Kaplan-Meier analysis. Lymphovascular invasion in the orchiectomy specimen, a high-risk pathologic feature, was also predictive of recurrence after primary RPLND. All 20 patients who recurred were treated with first-line chemotherapy and remained continuously disease free. CONCLUSION Most men with pathologic stage II disease treated with surgery alone in our series never experienced a recurrence. We did not observe a difference in recurrences between patients with pN1 and pN2. The recommendation for AC for pN2 disease may be overtreatment in most patients.
Objective
To investigate the incidence, risk factors and natural history of parastomal hernia (PSH).
Materials and Methods
We reviewed the records of patients who underwent radical cystectomy (RC) and ileal conduit (IC) procedure between 2007 and 2020. Patients who had available follow‐up computed tomography (CT) imaging were included in this study. All CT scans were re‐reviewed for detection of PSH according to Moreno‐Matias classification. Patients who developed hernia were followed up and classified into stable or progressive (defined as radiological upgrading and/or need for surgical intervention) groups. Multivariable Cox regression was performed to identify independent predictors of hernia development and progression.
Results
A total of 361 patients were included in this study. The incidence of radiological PSH was 30%, graded as I (56.5%), II (12%) and III (31.5%). The median (interquartile range [IQR]) time to radiological hernia was 8 (5–15) months. During the median (IQR) follow‐up of 27 (13–47) months in 108 patients with a hernia, 26% patients progressed. The median (IQR) time to progression was 12 (6–21) months. On multivariable analysis, female gender (hazard ratio [HR] 1.86), diabetes (HR 1.81), chronic obstructive pulmonary disease (COPD; HR 1.78) and higher body mass index (BMI; HR 1.07 for each unit) were independent predictors for radiological PSH development. No significant factor was found to be associated with hernia progression.
Conclusion
Radiological PSH after RC and IC occurred in 30% of patients, a quarter of whom progressed in a median time of 12 months. Female gender, diabetes, COPD and high BMI were independent predictors for radiological hernia development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
