Background: The European Association of Urology (EAU) guidelines advise an elective bilateral lymphadenectomy in clinically node-negative (cN0) patients with high-risk penile carcinoma (≥pT2, G3, or lymphovascular invasion [LVI]).

Objective: Our aim was to assess prognostic factors for occult metastasis and to determine whether current EAU guidelines accurately stratify patients at high risk.

Design, Setting, And Participants: Data of 342 cN0 patients with histologically proven invasive penile squamous cell carcinoma who had undergone the current dynamic sentinel node biopsy (DSNB) protocol were analysed.

Purpose: We identified pathological parameters of inguinal lymph node involvement with the aim of predicting pelvic lymph node involvement and survival.

Materials And Methods: A total of 308 patients with penile carcinoma and adequate followup were included in this study. The outcome of 102 patients who underwent lymphadenectomy for lymph node metastases was analyzed further.

There is evidence that a subset of penile carcinomas is caused by infection with high-risk human papillomavirus (HPV). However, extensive studies on the possible influence of HPV infection on clinical outcome of penile cancer are lacking. This investigation is aimed to examine the prevalence of high-risk HPV in a large series of penile squamous-cell carcinomas (SCCs) and to determine the relationship between HPV and survival.

Purpose: To determine the feasibility, toxicity, and immunologic effects of vaccination with autologous tumor cells retrovirally transduced with the GM-CSF gene, we performed a phase I/II vaccination study in stage IV metastatic melanoma patients.

Patients And Methods: Sixty-four patients were randomly assigned to receive three vaccinations of high-dose or low-dose tumor cells at 3-week intervals. Tumor cell vaccine preparation succeeded for 56 patients (88%), but because of progressive disease, the well-tolerated vaccination was completed in only 28 patients.

A comprehensive analysis of 53 penile carcinomas was performed to determine which mechanisms might be involved in the disruption of the p16(INK4A)/cyclin D/Rb pathway. To that end, human papillomavirus (HPV) presence, p16(INK4A) expression and promoter methylation, and expression of the BMI-1 polycomb gene product were studied. Sixteen (30%) of the carcinomas were found to harbour high-risk HPV DNA, 15 of which contained HPV 16.
