Demographic analysis of penectomies in France from 2019 to 2022

INTRODUCTION

Penectomy, whether partial (PP) or radical (RP), are mainly performed for oncological reason. It is a rare but impactful surgery, with significant bio-psycho-social consequences. As some countries moves towards centralization to improve patient outcomes, a demographic analysis of current management in France is needed. This study provides a demographic analysis of partial and total penectomies performed in France from 2019 to 2022.

METHODS

All 2150 total and partial penectomies performed in French healthcare facilities from 2019 to 2022 were included. Data were extracted from Visuchir, an Assurance Maladie data-visualization tool.

RESULTS

Incidence and ratio are stable, around 100 RP and 400 PP per year. The median age of patients was 78. Half of all penectomies were performed in private facilities (n=1115, 51.9%), with a higher rate of PP in these centers (55%, P<0.05). The rate of RP was significantly higher in comorbid patients than the fitter ones. In total, 423 centers reported at least one penectomy over the period, with significant variations in volume. In total, 251 facilities performed less than one procedure per year (59%), while larger centers performed up to 85 over the 4-year period. Length of stay was significantly shorter in high-volume centers.

CONCLUSION

This study shows the heterogeneous distribution and management of penectomies in France. Although there is no official centralization, the data reveal a "reference center" trend. Further data could help determine whether management in high-volume centers improves survival and quality of care for patients requiring penectomy.

French AFU Cancer Committee Guidelines-Update 2024-2026: Penile cancer

OBJECTIVE

Update of the recommendations for the management of penile lesions.

MATERIALS AND METHODS

Comprehensive PubMed review from 2022 of the literature on the diagnosis, treatment and follow-up of penile tumours. The level of evidence of the studies was assessed.

RESULTS

A total of 95% of infiltrating penile cancers are squamous cell carcinomas, one-third of which are related to human papillomavirus (HPV) infection. Clinical examination can reveal the size of the lesion, its location, its proximity to the urethral meatus and its infiltration depth. Urinary and sexual function should be assessed. Magnetic resonance imaging (MRI) is the gold standard for local assessment. Penile tumours are classified as low-risk (≤pT1a and well-differentiated G1), intermediate-risk (pT1a G2) or high-risk (≥pT1b, G3, or sarcomatoid contingent). Lymph node assessment in penile cancer is fundamental. The sentinel node technique is recommended for the evaluation of cN0 patients with tumours of intermediate risk or higher. 18FDG PET is recommended for cN+ patients. Surgery is the standard treatment locally and depends on the size, location and grade of the tumour. Topical treatment or brachytherapy may be indicated in some cases. Radical inguinal curettage (RIC) is recommended for stages cN1/cN2. Neoadjuvant chemotherapy is recommended for patients with cN3-stage lesions, combined with RIC in responders. Metastatic forms may be treated with palliative chemotherapy and immunotherapy as part of a clinical trial.

CONCLUSION

The treatment of penile cancer is essentially surgery, with or without chemotherapy in the case of lymph node involvement. The main prognostic factor is lymph node involvement, which justifies early diagnostic and therapeutic management of the inguinal areas.

Multimodal Therapy of Locally-Advanced Penile Cancer: A Case Report With Literature Review

Cancer of the penis is a rare tumor that occurs in the elderly. Because of its rarity, it is often not diagnosed early, and its treatment poses difficulties for practicing oncologists. We report the case of an elderly patient treated for locally advanced squamous cell carcinoma (SCC) of the penis, with a review of the literature. A 71-year-old man, who had been complaining of pruritus on the penis two years ago, presented with an ulcerated lesion on the prepuce and the glans. A biopsy of the lesion with pathological study showed a SCC of the penis. Pelvic MRI showed tumor thickening centered on the glans of the penis, infiltrating the fascia and the spongy urethra with discrete upstream dilatation and bilateral inguinal adenomegaly. CT scan of the neck, chest, abdomen, and pelvis showed no secondary localizations. Treatment initially consisted of carcinological surgery by a partial penectomy with bilateral inguinal lymph node dissection. The tumor was therefore classified as pT3N3M0. A PET CT scan performed later was in favor of local and regional recurrence. Surgery was not feasible, so concomitant chemo-radiotherapy was indicated at a total dose of 70 Gy in 35 fractions of 2 Gy concomitantly with platinum-based chemotherapy, withgood evolution.

French AFU Cancer Committee Guidelines - Update 2022-2024: penile cancer

OBJECTIVE

To update French oncology guidelines concerning penile cancer.

METHODS

Comprehensive Medline search between 2020 and 2022 upon diagnosis, treatment and follow-up of testicular germ cell cancer to update previous guidelines. Level of evidence was evaluated according to AGREE-II.

RESULTS

Epidermoid carcinoma is the most common penile cancer histology. Physical examination is mandatory to define local and inguinal nodal cancer stage. MRI with artificial erection can help to assess deep infiltration in cases of organsparing intention. Node negative patients (defined by palpation and imaging) will present micro nodal metastases in up to 25% of cases. Invasive lymph node assessment is thus advocated except for low risk patients. Sentinel node dynamic biopsy is the first line technique. Modified bilateral inguinal lymphadenectomy is an option with higher morbidity. 18-FDG-PET is recommended in patients with palpable nodes. Chest, abdominal and pelvis computerized tomography is an option. Fine needle aspiration (when positive) is an easy way to assess inguinal palpable node pathological involvement. Its results determine the type of lymphadenectomy to be performed (for diagnostic or curative purposes). Treatment is mostly surgical. Free margins status is essential, but it also has to be organ-sparing when possible. Brachytherapy and topic agents can cure in selected cases. Lymph node assessment should be synchronous to the removal of the tumour when possible. Limited inguinal lymph node involvement (pN1 stage) can be cured with the only lymphadenectomy. In case of larger lymph node stage, one should consider multidisciplinary treatment including chemotherapy and inclusion in a trial.

CONCLUSIONS

Penile cancer needs demanding surgery to be cured, surrounded by chemotherapy in node positive patients. Lymph nodes involvement is a major prognostic factor. Thus, inguinal node assessment cannot be neglected.

Brachytherapy for oligometastatic prostate cancer to the penis

The origin of penile metastases is in 70% of cases from primary pelvic cancers (genitourinary and recto-sigmoid primary tumors). The prognosis is poor and it is often associated with synchronous bone metastases at the time of diagnosis. We present the case of a 61-year-old patient who developed a penile induration 7 years after radical prostatectomy followed by adjuvant external beam radiation therapy for high-risk prostatic adenocarcinoma. Biopsies confirmed the metastatic localization and a detailed assessment failed to find any further remote lesions. Faced with this penile oligometastatic prostate cancer, we proposed an ablative treatment based on interstitial multi-catheter high-dose rate brachytherapy. At the six-month follow-up, clinical examination and ⁶⁸Ga-PSMA-11-PET confirmed a complete response of the penile tumor without new lesion at a distance.
