1Department of Urology, State Key Laboratory of Oncology in Southern China, Collaborative Innovation Center for Cancer Medicine, Sun Yat-sen University Cancer Center, Guangzhou, China.

Background: The purpose of this study was to evaluate the efficacy and safety of PD-1 blockade combined with cisplatin and paclitaxel (TP)-based chemotherapy as first-line treatment for advanced penile squamous cell carcinoma (PSCC).

Patients And Methods: A retrospective review was performed of 32 eligible patients with high-risk stage IV (cN3M0-1) PSCC who received first-line PD-1 blockade combined with TP-based chemotherapy at 5 medical centers (2019-2023). Clinical responses were assessed using RECIST version 1.

Penile squamous cell carcinoma (pSCC) represents an uncommon malignancy characterized by stagnant mortality, psychosexual distress, and a highly variable prognosis. Currently, the WHO distinguishes between human papillomavirus (HPV) related and HPV independent pSCC. Recently, there has been an evolving line of research documenting the enrichment of HPV-independent pSCC with a high tumor mutational burden (TMB) and programmed death ligand-1 (PD-L1) expression, as well as clusters of genes associated with HPV status.

Background: Inguinal lymph node (LN) dissection (iLND) is mandatory in cN2 penile squamous cell carcinoma (PSCC). Open iLND (OIL) is often omitted due to the high rate of complications. A minimally invasive approach may reduce morbidity; however, evidence supporting its role to treat bulky nodes is limited.

Objective: To prospectively validate the diagnostic performance of Clino-radio-pathological Risk Scoring System (CRiSS) for prediction of inguinal lymph-node metastasis (ILNM) in squamous cell carcinoma of penis.

Materials And Methods: A prospective observational study of all patients with SCC penis was conducted between January 1, 2021, and December 31, 2023, at our institute. Data regarding all CRiSS parameters and MRI features of >8mm size and presence of necrosis or irregular outline were recorded, and patients were assigned CRiSS scores and groups.

Verrucous carcinoma, a well-differentiated variant of squamous cell carcinoma with low-grade malignancy, is often associated with localized human papillomavirus (HPV) infection and excessive penile foreskin. We report a 45-year-old male who presented with a verrucous plaque on the glans penis for over four months, along with itching. Examination revealed a verrucous, erosive lesion with a cauliflower-like surface, firm texture, and irregular shape, accompanied by pain, bleeding, and a foul odor.

Identification of new tissue markers for the monitoring and standardization of penile cancer according to the degree of differentiation.

November 2024

Department of Medicine and Medical Specialities, Faculty of Medicine and Health Sciences, Network Biomedical Research Center for Liver and Digestive Diseases (CIBEREHD), University of Alcalá, Alcala de Henares, Spain.

Article Synopsis
  • - Penile cancer is a rare type of tumor, more frequently seen in low- and middle-income countries, with major risk factors being age, ethnicity, smoking, hygiene, and HPV infection.
  • - Early detection can lead to high cure rates (up to 80%), but late diagnosis significantly lowers survival chances, especially when the cancer has spread.
  • - The study assesses various biomarkers related to cell growth, inflammation, and other processes in penile squamous cell carcinoma, suggesting that the degree of cell differentiation affects these biomarkers' expression, which may help in predicting disease outcomes.

Gene Expression Profiling of the Peritumoral Immune Cell Infiltrate of Penile Squamous Cell Carcinomas.

Int J Mol Sci

November 2024

Dr. Senckenberg Institutes of Pathology & Human Genetics, Goethe University Frankfurt, Theodor-Stern-Kai 7, 60596 Frankfurt am Main, Germany.

Article Synopsis
  • - Penile carcinomas are uncommon in Europe and their poor prognosis in advanced stages necessitates further research, particularly concerning the role of immune cell infiltrates in tumor behavior.
  • - A study analyzed twelve cases of penile squamous cell carcinomas, focusing on their immune cell infiltration patterns using immunohistochemistry and RNA expression profiling, revealing distinct clustering based on immune cell density.
  • - The analysis found that increased immune cell infiltration correlated with specific gene upregulation and various immune functions, while no link to HPV infection status was identified, supporting the validity of findings through subsequent immunohistochemical studies.

Article Synopsis
  • The article presents a clinical case of a young patient with HPV-associated penile intraepithelial neoplasia (PIN), specifically the erythematous form of bowenoid papulosis.
  • It highlights the issues of delayed diagnosis due to improper diagnostic approaches and a lack of awareness among doctors about cancer-related diseases.
  • The piece emphasizes the significance of early detection in preventing progression to more severe conditions like squamous cell penile carcinoma, detailing the different subtypes of PIN and their varying risks of leading to cancer.

Article Synopsis
  • Shortwave-infrared (SWIR) imaging is suggested to improve contrast in fluorescence-guided surgery compared to near-infrared (NIR) imaging, but it has only been tested in animal studies so far.
  • The study aims to evaluate the benefits of SWIR imaging in clinical samples treated with the NIR dye cetuximab-IRDye800CW, focusing on tumor-targeted applications in penile and head and neck cancers.
  • Results indicate that while SWIR performs similarly to NIR in penile cancer samples, NIR outperforms SWIR in most criteria for head and neck cancer due to high background autofluorescence, suggesting that SWIR may enhance contrast in some situations but not universally across all clinical

Article Synopsis
  • Mixed carcinomas, which represent about 10% of penile carcinomas, consist of multiple distinct histological subtypes, categorized by the World Health Organization (WHO) into two groups based on their HPV association.
  • The study aimed to detect HPV genotypes in these mixed tumors, revealing a higher HPV positivity rate (46%) in carcinomas with warty/basaloid features compared to a low rate (7%) in non-warty/basaloid types.
  • HPV16 was the most commonly identified genotype (65%), and the presence of HPV-associated morphology above 20% in mixed tumors is critical for classification as HPV-associated, in accordance with WHO guidelines.

Article Synopsis
  • Penile squamous cell carcinoma (PSCC), mainly affecting poorer regions, has risk factors such as low socioeconomic status, phimosis, and HPV infection, but its immune response and treatment options are still unclear.
  • The study collected data from 30 PSCC patients (mostly HPV-positive) and 19 healthy donors to analyze immune cell behavior and utilize a tumor-mimicking environment created from HPV-positive tumor cultures.
  • Results indicated that HPV-positive tumors had fewer T lymphocytes and that dendritic cells in these patients were less mature and had lower activation compared to healthy controls, potentially affecting the immune response and disease progression.

Penile and Scrotal Porokeratosis: A Single-Institution Experience.

Am J Dermatopathol

November 2024

Pathologists Departments of Dermatology and Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN.

Article Synopsis
  • The study investigates porokeratosis localized to the penis and scrotum, analyzing data from patients diagnosed between 2000 and 2022.
  • Nine patients were included, with a median age of 51, and most had either penile or scrotal lesions, while one had extensive lesions affecting multiple areas.
  • The findings indicate that clinical diagnosis can be challenging and highlights the importance of histopathological examination, as follow-ups showed no recurrence or malignant transformation in patients after biopsy removal.
