Clinical Outcomes and Prognostic Factors in Patients With Penile Carcinoma: A Sub-Analysis From Meet-URO 23 (I-RARE) Registry Study.

INTRODUCTION: Penile squamous cell carcinoma (PSCC) is a rare tumor with an aggressive behavior. The Meet-URO 23/I-RARE registry includes rare genitourinary malignancies. We extracted patients with PSCC to conduct a retrospective study aimed at assessing clinical outcomes and prognostic factors. PATIENTS AND METHODS: Primary endpoints were overall survival and progression-free survival. Prognostic factors for OS and PFS were analyzed using univariate and multivariate analysis. From the Meet-URO 23/I-RARE database, we extracted 128 patients with diagnosis of PSCC. About 48% of patients underwent first-line of therapy. RESULTS: In the overall population, median OS from diagnosis was 34.6 months. Significant differences in median OS were observed according to ECOG PS at diagnosis (57.3 months vs. 8.3 months; P < .001), and median age (≤77y 88.8 months vs. >77y 26 months; P = .013). At multivariate analysis, ECOG PS 2-4 at diagnosis (HR 3.04) and lymph node metastases (HR 2.49) were independently associated with a higher risk of death. Among patients undergoing first-line therapy (n = 61), median OS was 12.3 months, and a statistically significant difference was found according to type of response to first-line (DCR 24.4 months vs. PD 7.1 months; P < .001). Multivariate analysis showed that only age >77 years was associated with a worse OS (HR 2.16). A statistically significant difference in PFS was found according to platinum plus 5-fluorouracil versus platinum plus taxane (4.9 vs. 3.4 months; P = .036) and regimens with 2 versus 3 drugs (3.4 vs. 8.6 months; P = .019). At the multivariate analysis only regimens with platinum plus taxane were associated with worse PFS (HR 2.83). CONCLUSION: In our registry study, PSCC is confirmed to be an aggressive disease. Poor ECOG PS, presence of lymph node metastases, and higher age at diagnosis appear to be associated with worse survival outcomes.

The landscape of penile cancer research in Germany and Austria: a survey among professors in academic centers holding chair positions and results of a literature search.

BACKGROUND: Research on penile cancer (PeCa) is predominantly conducted in countries with centralized treatment of PeCa-patients. In Germany and Austria (G + A), no state-regulated centralization is established, and no information is available on how PeCa-research is organized. METHODS: Current research competence in PeCa was assessed by a 36-item questionnaire sent to all chairholders of urological academic centers in G + A. Based on PubMed records, all scientific PeCa-articles of 2012-2022 from G + A were identified. Current research trends were assessed by dividing the literature search into two periods (P1: 2012-2017, P2: 2018-2022). A bibliometric analysis was supplemented. RESULTS: Response rate of the questionnaire was 75%, a median of 13 (IQR: 9-26) PeCa-patients/center was observed in 2021. Retrospective case series were conducted by 38.9% of participating clinics, while involvement in randomized-controlled trials was stated in 8.3% and in basic/fundamental research in 19.4%. 77.8% declared an interest in future multicenter projects. 205 PeCa-articles were identified [median impact factor: 2.77 (IQR: 0.90-4.37)]. Compared to P1, P2 showed a significant increase in the median annual publication count (29 (IQR: 13-17) vs. 15 (IQR: 19-29), p < 0.001), in multicenter studies (79.1% vs. 63.6%, p = 0.018), and in multinational studies (53% vs. 28.9%, p < 0.001); the proportion of basic/fundamental research articles significantly declined (16.5% vs. 28.9%, p = 0.041). Four of the top-5 institutions publishing PeCa-articles are academic centers. Bibliometric analyses revealed author networks, primary research areas in PeCa, and dominant journals for publications. CONCLUSIONS: Given the lack of centralization in G + A, this analysis highlights the need for research coordination within multicenter PeCa-projects. The decline in basic/fundamental research should be effectively addressed by the allocation of funded research projects.

Long-term follow-up of comparative study of open and endoscopic lymphadenectomy in patients with penile carcinoma.

BACKGROUND: Penile carcinoma is an uncommon cancer that develops in the penis tissue. The standard surgical method to manage regional lymph nodes after local excision is radical inguinal lymphadenectomy, but it has a high rate of complications. The objective of this retrospective study was to compare the long-term outcomes of endoscopic inguinal lymphadenectomy and open inguinal lymphadenectomy in patients with penile carcinoma. METHODS: The study included patients diagnosed with penile carcinoma who underwent open inguinal lymphadenectomy (n = 23) or endoscopic inguinal lymphadenectomy (n = 27) at a single hospital between January 2013 and January 2021. Operation time, blood loss, drainage, hospital stay, postoperative complications, and survival rates were assessed and compared between the two groups. RESULTS: The two groups were comparable in terms of age, tumor size and stage, inguinal lymph nodes, and follow-up. The endoscopic group had significantly lower blood loss (27.1 ± 1.5 ml vs 55.0 ± 2.7 ml, P < 0.05), shorter drainage time and hospital stay (4.7 ± 1.1 days vs 8.1 ± 2.2 days, and 13.4 ± 1.0 days vs 19 ± 2.0 days, respectively, P < 0.05), and longer operation time compared to the open group (82.2 ± 4.3 min in endoscopic group vs 53.1 ± 2.2 min in open group, P < 0.05). There were significant differences in the incidence of incisional infection, necrosis, and lymphorrhagia in both groups (4 vs 0, 4 vs 0, and 2 vs 0, respectively, P < 0.05). The inguinal lymph node harvested was comparable between the two groups. The mean follow-up time was similar for both groups (60.4 ± 7.7 m vs 59.8 ± 7.3 m), and the recurrence mortality rates were not significantly different. CONCLUSIONS: The study shows that both open and endoscopic methods work well for controlling penile carcinoma in the long term. But the endoscopic approach is better because it has fewer severe complications. So, the choice of surgery method might depend on factors like the surgeon's experience, what they like, and what resources are available.

Simultaneous Bilateral Video-Endoscopic Inguinal Lymphadenectomy for Penile Carcinoma: Surgical Setting, Feasibility, Safety, and Preliminary Oncological Outcomes.

INTRODUCTION: Inguinal lymph node dissection (ILND) plays an important role for both staging and treatment purposes in patients diagnosed with penile carcinoma (PeCa). Video-endoscopic inguinal lymphadenectomy (VEIL) has been introduced to reduce complications, and in those patients elected for bilateral ILND, a simultaneous bilateral VEIL (sB-VEIL) has also been proposed. This study aimed to investigate the feasibility, safety, and preliminary oncological outcomes of sB-VEIL compared to consecutive bilateral VEIL (cB-VEIL). MATERIAL AND METHODS: Clinical N0-2 patients diagnosed with PeCa and treated with cB-VEIL and sB-VEIL between 2015 and 2023 at our institution were included. Modified ILND was performed in cN0 patients, while cN+ patients underwent a radical approach. Intra- and postoperative complications, operative time, time of drainage maintenance, length of hospital stay and readmission within 90 days, as well as lymph node yield, were compared between the two groups. RESULTS: Overall, 30 patients were submitted to B-VEIL. Of these, 20 and 10 patients underwent cB-VEIL and sB-VEIL, respectively. Overall, 16 (80%) and 7 (70%) patients were submitted to radical ILND due to cN1-2 disease in the cB-VEIL and sB-VEIL groups, respectively. No statistically significant difference emerged in terms of median nodal yield (13.5 vs. 14, p = 0.7) and median positive LNs (p = 0.9). sD-VEIL was associated with a shorter operative time (170 vs. 240 min, p < 0.01). No statistically significant difference emerged in terms of intraoperative estimated blood loss, length of hospital stay, time to drainage tube removal, major complications, and hospital readmission in the cB-VEIL and sB-VEIL groups, respectively (all p > 0.05). CONCLUSIONS: Simultaneous bilateral VEIL is a feasible and safe technique in patients with PeCA, showing similar oncological results and shorter operative time compared to a consecutive bilateral approach. Patients with higher preoperative comorbidity burden or anesthesiological risk are those who may benefit the most from this technique.

Cemiplimab as First Line Therapy in Advanced Penile Squamous Cell Carcinoma: A Real-World Experience.

In the treatment of cancer, immune checkpoint inhibitors (ICIs) have demonstrated significantly greater effectiveness compared to conventional cytotoxic or platinum-based chemotherapies. To assess the efficacy of ICI's in penile squamous cell carcinoma (pSCC) we performed a retrospective observational study. We reviewed electronic medical records of patients with penile squamous cell carcinoma (SCC), diagnosed between January 2020 and February 2023. Nine patients were screened, of whom three were ineligible for chemotherapy and received immunotherapy, cemiplimab, in a first-line setting. Each of the three immunotherapy-treated patients achieved almost a complete response (CR) after only a few cycles of therapy. The first patient had cerebral arteritis during treatment and received a high-dose steroid treatment with resolution of the symptoms of arteritis. After tapering down the steroids dose, the patient continued cemiplimab without further toxicity. The other two patients did not have any toxic side effects of the treatment. To the best of our knowledge, this is the first real world report of near CR with cemiplimab as a first-line treatment in penile SCC.

Case Report: Primary Ewing Sarcoma of the Penis.

Background: Ewing sarcoma is a malignancy that commonly affects the skeletal system and primary extraskeletal involvement is rare. Extraskeletal Ewing sarcoma (EES) arises in soft tissue anywhere in the body. These are very rarely seen aggressive tumours. There have been only 7 reported cases of EES of penis. Case Presentation: We report a 22-year-young patient who presented to our hospital with a ulcero-proliferative growth in the shaft of penis. There were no other complaints indicating any metastasis. Incisional biopsy was suggestive of invasive malignancy. He was scheduled for a partial penectomy. Final HPE and IHC were suggestive of EES. Conclusion: EES as a subtype of Ewing sarcoma is rare and it can occur in any soft tissue site. Hence, clinicians need to differentiate this entity from other soft tissue sarcomas. Early diagnosis and timely treatment of EES are pivotal for a favourable prognosis due to its aggressive nature.

Case Report: Optimum excision with split skin graft closure in the management of penile sebaceous carcinoma.

Sebaceous carcinoma (SC) is a rare malignant skin neoplasm derived from the meibomian gland of adnexal epithelium, which is frequently confused with basal cell carcinoma (BCC), exhibiting sebaceous differentiation and commonly found in the head and neck regions. We report a case of penile sebaceous carcinoma, an extremely rare anatomical site for SC. A 68-year-old man presented with a 4-month history of painless, non-healing ulcerated nodules over the left side of the penile shaft. Wedge biopsy showed adenocarcinoma with signet ring differentiation. We proceeded with wide local excision (WLE) of the lesion with the inclusion of the indurated skin and 5 mm of normal margin, followed by primary closure of the scrotal defect and split skin grafting of the penile shaft by using a thigh skin donor. The final histopathological examination revealed sebaceous carcinoma with pagetoid spread. The patient achieved recurrence-free survival without any form of adjuvant therapy after 4 years of follow-up.

Influence of Race/Ethnicity and Household Median Income on Penile Cancer Mortality.

INTRODUCTION: Penile cancer, while relatively rare in developed nations, presents substantial disparities in outcomes among different demographic groups. Previous research has shown race/ethnicity and socioeconomic status, often proxied by household median income, to be critical determinants of health outcomes across various diseases. OBJECTIVE: This study examines the association of race/ethnicity and household median income with survival among penile cancer patients in the United States. METHODS: We utilized the Surveillance, Epidemiology, and End Results (SEER) Registry to identify patients with a primary diagnosis of penile malignancies from 2000 to 2019. Our primary outcome of interest was the hazard of death following a diagnosis of penile cancer. We utilized the Cox regression model to explore the association between race/ethnicity and median household income and how this influences survival among these patients. We adjusted for patients' characteristics, disease stage at presentation, and treatment modalities. RESULT: Of the 6,520 penile cancer patients identified, 5,242 (80.4%) had primary malignancies. The distribution of patients was as follows: 64.1% non-Hispanic Whites, 8.9% non-Hispanic Blacks, 20.8% Hispanics, and 6.2% from other racial/ethnic groups. The median diagnosis age was 66 years (interquartile range: 56-74). Survival rates at 5, 10, and 15 years showed racial disparities: 76.4%, 72.5%, and 69.7% for non-Hispanic Whites; 70.6%, 64.1%, and 61.1% for non-Hispanic Blacks; and 70.5%, 67.4%, and 65.6% for Hispanics. Multivariate Cox regression revealed worst survival for Black (HR=1.40; 95% CI=1.08-1.81, p=0.01) and Hispanic patients (HR=1.24; 95% CI=1.01-1.52, p=0.04). No association was found between median household income and survival. Interaction analysis indicated that the poorest Black men had worse outcomes than the poorest Whites did (HR=2.08; 95% CI=1.27-3.41, p=0.003). CONCLUSION: Survival rates for non-Hispanic Black and Hispanic patients are significantly lower than those for non-Hispanic Whites. Furthermore, survival is worse for low-income Black patients than their White counterparts in the same income bracket.

Study on naked eye tracing of inguinal sentinel lymph nodes in penile cancer patients with carbon nanoparticle suspension injection.

Objective: Exploratory study of the effect and clinical value of carbon nanoparticle suspension injection (CNSI) as a tracer for inguinal sentinel lymph nodes in penile cancer. Method: We selected 29 patients with penile cancer in our department from January 2019 to October 2022. According to whether the CNSI tracer was injected during the pathological biopsy of the inguinal lymph nodes, the enrolled patients were assigned to the control group, the group in which CNSI was injected 12 h before the surgery (12HBS group) and the group in which CNSI was injected 0.5 h before the surgery (0.5HBS group). Evaluating the effectiveness of CNSI as a lymphatic tracer involves analyzing the following: its safety, the statistical analysis of the detection rate (DR) of different groups, the number of lymph nodes sent for each case (NOLNSFEC), the difference of positive rate of lymphatic metastasis (PROLM), and operation time (OT). Results: The lymph nodes in the 12HBS group and 0.5HBS group had an obvious black staining appearance, and no adverse reactions or surgical complications were found. Most of the black-stained areas caused by CNSI injection were removed with penile excision, which did not affect the postoperative appearance. This did not affect the pathological analysis. The DR of lymph nodes in the 12HBS group was higher (p < 0.05) than that in the control group. More lymph nodes were removed for examination (p < 0.05), which improved the efficiency of surgery. Compared with the 12HBS group, the number of lymph nodes removed in the 0.5HBS group decreased (p < 0.05). The OT was shortened (p < 0.05), but there was no significant difference in the DR and PROLM. Conclusion: CNSI was applied to the naked-eye tracing of inguinal sentinel lymph nodes in penile cancer, which is safe and efficient. Injection of CNSI 0.5 h before surgery can help identify the "foremost position" of sentinel lymph nodes and reduce surgical trauma.

Multi-parametric MRI without artificial erection for preoperative assessment of primary penile carcinoma: A pilot study on the correlation between imaging and histopathological findings.

Purpose: We aimed to evaluate the diagnostic potential of non-erectile multi-parametric magnetic resonance imaging (mpMRI) for preoperative assessment of primary penile squamous cell carcinoma (SCC). Method: Twenty-five patients who underwent surgery for penile SCC were included. Preoperative mpMRI without artificial erection was performed in all patients. The preoperative MRI protocol consisted of high-resolution morphological and functional sequences (diffusion-weighted imaging and dynamic contrast-enhanced MRI perfusion) covering the penis and lower pelvis. T and N staging, according to the 8th edition of the Union for International Cancer Control TNM classification, as well as the largest diameter and thickness/infiltration depth of the primary lesions were determined in all patients. Imaging data were retrospectively collected and compared with the final histopathology reports. Results: Very good agreement was observed between MRI and histopathology for the involvement of corpus spongiosum (p = 0.002) and good agreement was observed for the involvement of penile urethra and tunica albuginea/corpus cavernosum (p < 0.001 and p = 0.007, respectively). Good agreement was observed between MRI and histopathology for overall T staging and weaker, but still good agreement was observed for N staging (p < 0.001 and p = 0.002, respectively). A strong and significant correlation was observed between MRI and histopathology for the largest diameter and thickness/infiltration depth of the primary lesions (p < 0.001). Conclusions: Good concordance was observed between MRI and histopathological findings. Our initial findings indicate that non-erectile mpMRI is useful in preoperative assessment of primary penile SCC.

PD-L1 is associated with the prognosis of penile cancer: A systematic review and meta-analysis.

Background: Previous studies have explored the role of PD-L1 in the survival outcomes of penile cancer patients with controversies existed. Thus, the meta-analysis was conducted to report and review the association between PD-L1 and survival in penile cancer patients. Methods: PubMed, Cochrane Library, EMBASE, and Web of Science were all searched, screened, and reviewed by June 1, 2022. Hazard ratio (HR) was used to evaluate the relationship between PD-L1 and survival outcome, and odds ratio (OR) was for tumor features. Results: Nine retrospective studies (1,003 patients) were incorporated. The prevalence of PD-L1 in patients with penile cancer was 51.4% (95% CI = 42.1%-60.8%, I 2 = 88.5%). Higher PD-L1 on tumor cells was related to shorter cancer-specific survival (CSS) in patients (HR = 1.578, 95% CI = 1.227-2.029, I 2 = 23.3%), but had no associations with overall survival (OS) (HR = 1.123, 95% CI = 0.511-2.465, I 2 = 0.0%). Subgroup analysis indicated that higher PD-L1 was related to shorter CSS in Caucasus (HR = 1.827, 95% CI = 1.355-2.465, I 2 = 0.0%) only. Furthermore, PD-L1 had associations with tumor stage (pT1 vs. pT2-4, OR = 0.480, 95% CI = 0.346-0.667, P = 0.001) and tumor grade (Well and moderate vs. Poor, OR = 0.377, 95% CI = 0.264-0.538, P < 0.001). PD-L1 positivity was also related to lymph node (LN) status (pN0/NX vs. pN1-3, OR = 0.541, 95% CI = 0.385-0.759, P = 0.001) and HPV status (Positive vs. Negative, OR = 0.510, 95% CI = 0.322-0.810, P = 0.003). A trend toward statistical significance between PD-L1 and histological types was also observed (Usual SCC vs. Others, OR = 1.754, 95% CI = 0.984-3.124, P = 0.070). Conclusions: PD-L1 over-expression was related to worse survival outcomes and several clinicopathological features of penile cancer. PD-L1 expression can be applied to select appropriate treatment strategies for penile malignancies.

High-Dose-Rate Brachytherapy as an Organ-Sparing Treatment for Early Penile Cancer.

BACKGROUND: Low-dose-rate brachytherapy is an effective organ-sparing treatment for patients with early-stage penile cancer. However, only limited data are available on the role of high-dose-rate brachytherapy (HDR-BT) in this clinical setting. METHODS: Between 2002 and 2020, 31 patients with early penile cancer were treated at our center with interstitial HDR BT at a dose of 18 × 3 Gy twice daily. A breast brachytherapy template was used for the fixation of stainless hollow needles. RESULTS: The median follow-up was 117.5 months (range, 5-210). Eight patients (25.8%) developed a recurrence; of these, seven were salvaged by partial amputation. Six patients died of internal comorbidities or a second cancer. The probability of local control at 5 and 10 years was 80.7% (95% CI: 63.7-97.7%) and 68.3% (95% CI: 44.0-92.6%), respectively. Cause-specific survival was 100%. Only one case of radiation-induced necrosis was observed. The probability of penile sparing at 5 and 10 years was 80.6% (95% CI: 63.45-97.7%) and 62.1% (95% CI: 34.8-89.4%), respectively. CONCLUSIONS: These results show that HDR-BT for penile cancer can achieve results comparable to LDR-BT with organ sparing. Despite the relatively large patient cohort-the second largest reported to date in this clinical setting-prospective data from larger samples are needed to confirm the role of HDR-BT in penile cancer.

Sintilimab-Induced Diabetic Ketoacidosis in a Patient with Radiation and Multichemorefractory Penile Cancer: A Case Report and Literature Review.

Penile squamous cell carcinoma (PSCC) is a rare disease. The treatment options for advanced penile cancer are often limited, and the prognosis remains poor. We reported a 52-year-old male recurrent and metastatic PSCC patient with high PD-L1 expression (90%) and TMB (14.4 muts/Mb). He had undergone penectomy, bilateral inguinal lymph node dissection, and excision of the abdominal wall mass. Despite cisplatin-based concurrent chemoradiotherapy and sequential chemotherapy with docetaxel plus cisplatin then being carried out, the carcinoma still progressed. The patient then obtained progression-free survival with continuous sintilimab, although he experienced the new onset of ICI-induced diabetes after 24 cycles of sintilimab and required sustained insulin treatment. He had negative type 1 diabetes-associated autoantibodies and the susceptible HLA genotype DR3-DQ2 haplotype. This is the first patient with radiation and multichemorefractory PSCC who has obtained the remarkable anti-tumor effect of partial regression exceeding 32 months during continuous sintilimab and anlotinib treatment.

Mohs microsurgery for localized penile carcinoma: 10 year retrospective review of local recurrence rates and surgical complications.

PURPOSE: To investigate the local recurrence rates of men treated with Mohs microsurgery (MMS) for penile carcinoma. The secondary outcome was surgical complications from the MMS procedure or the subsequent reconstructive procedures. MATERIALS AND METHODS: All patients from 2010 to 2020 with penile carcinoma at our institution were seen in a multidisciplinary setting. Patients with Ta, Tis, T1, and T2 disease were considered candidates for MMS. Clinical and pathologic data were collected for analysis. Local recurrence rates were stratified by stage and complications reported per the Clavien-Dindo Grade. RESULTS: A total of 43 patients met inclusion criteria. The median age at diagnosis was 64 years. Stage distribution was Ta in 4.7%, Tis in 58.1%, T1a in 14.0%, T1b in 7.0%, and T2 in 16.3%. No patients had a positive surgical margin after MMS. The overall local recurrence rate was 2% (n = 1) at a median of 47 months. Local recurrence rates at 1, 3, and 5 years for Ta, Tis, and T1 patients were 0%. Local recurrence rates for T2 patients were 14% at 1 year. Complications occurred in 12% (n = 5), all of which were Clavien-Dindo ≤ III. CONCLUSIONS: MMS provides effective local control for Ta, Tis, and T1 penile cancer with an overall local recurrence rate of 2% and an acceptable complication rate. A multi-disciplinary team involving urologic oncology, reconstructive urology, and MMS is essential to patient management.

Tumor Location May Independently Predict Survival in Patients With M0 Squamous Cell Carcinoma of the Penis.

Background: To determine the association between tumor location and both clinicopathological characteristics and the survival of patients with M0 squamous cell carcinoma of the penis (SCCP). Methods: Data of 455 patients diagnosed with M0 SCCP between 1975 and 2018 were collected from the Surveillance, Epidemiology, and End Results (SEER) database of the United States National Cancer Institute. The effects of tumor location on overall survival (OS) and penile carcinoma-specific survival (PCSS) were analyzed using the Kaplan-Meier method. The Cox proportional hazards regression model was used to determine the impact of tumor location on PCSS. Results: SCCP was more likely to occur in the prepuce or glans (90%). Although no significant difference was observed between the OS of patients with M0 SCCP in the prepuce or glans and those with M0 SCCP in the body of the penis (p = 0.307), the former had better PCSS (p = 0.024). Moreover, M0 SCCP in the prepuce or glans was also significantly associated with better PCSS in patients with advanced age (age ≥ 60 years, p = 0.011), other ethnicities (p = 0.003), T2-T4 stage (p = 0.036), larger tumors (≥3 cm, p = 0.001), no regional lymph nodes removed (p = 0.044), and radical surgery (p = 0.027). Multivariate analysis confirmed that tumor location is an independent prognostic factor for patients with M0 SCCP [hazard ratio (HR) 1.881, p = 0.026]. Conclusions: Tumor location is an independent prognostic factor for patients with M0 SCCP, and tumors in the prepuce or glans portend better PCSS.

Importance of Addressing the Psychosocial Impact of Penile Cancer on Patients and Their Families.

OBJECTIVE: In this article we review the quality of life and the psychosocial and functional outcomes experienced by patients and their partners following penile cancer diagnosis and treatment. DATA SOURCES: A literature search for primary articles related to patient reported outcomes following penile cancer treatment was conducted using the electronic database PubMed. CONCLUSION: Penile cancer is a rare malignancy in the United States, and it carries an excellent prognosis if diagnosed early. However, increased survivorship carries devastating long-term consequences on the mental health of patients and their families. Factors impacting the quality of life of patients include sexual dysfunction, cosmetic changes, voiding dysfunction, depression, and anxiety. Treatment modalities vary depending on the extent of the cancer but include medical, interventional, and surgical options. IMPLICATIONS FOR NURSING PRACTICE: The multidisciplinary team can support patients and their partners to develop, test and deliver posttreatment survivorship interventions to optimize psychosocial well-being and quality of life outcomes for this rare disease.

A laparoscopic radical inguinal lymphadenectomy approach partly preserving great saphenous vein branches can benefit for patients with penile carcinoma.

BACKGROUND: Inguinal lymphadenectomy (iLAD) is effective for penile carcinoma treatment, but usually results in many complications. This study aims to clinically evaluate the feasibility and clinical significance of a laparoscopic radical iLAD approach partly preserving great saphenous vein branches for penile carcinoma patients. METHODS: A total of 48 patients with penile cancer who underwent laparoscopic radical iLAD with retention of the great saphenous vein in Henan Cancer Hospital from 2012 Jan to 2020 Dec were included in this study. Sixteen penile carcinoma patients who underwent laparoscopic radical iLAD preserving parts of superficial branches of the great saphenous vein were identified as the sparing group, and the matched 32 patients who incised those branches were identified as control group. This new procedure was performed by laparoscopy, preserving parts of superficial branches of the great saphenous vein, superficial lateral and medial femoral veins. Clinicopathological features and perioperative variables were recorded. Postoperative complications, including skin flap necrosis, lymphorrhagia, and lower extremity edema were analyzed retrospectively. RESULTS: We found that the operative time of the sparing group is significantly longer than the control group (p = 0.011). There was no statistical difference in intraoperative blood loss, the lymph node number per side, average time to remove the drainage tube and postoperative hospital stay between the two groups. Compared to the control group, the sparing group showed a significantly decreased incidence of lower extremity edema (p = 0.018). The preservation of parts of superficial branches of the great saphenous vein was mainly decreased the incidence of edema below ankle (p = 0.034). CONCLUSIONS: This study demonstrated that the iLAD with preserving parts of superficial branches of the great saphenous vein, with a decreased incidence of postoperative complications, is a safe and feasible approach for penile cancer.

[Penile intraepithelial neoplasia]. / Les néoplasies intraépithéliales peniennes.

Penile carcinogenesis can be superposed on vulvar carcinogenesis, with two pathways : with or without a link to HPV. Penile squamous cell carcinomas arise from precursor lesions: penile intraepithelial neoplasia (PeIN) defined by the presence of intraepithelial atypia, which can progress to invasive squamous cell carcinoma. Differentiated PeINs not linked to HPV, affect elderly men with inflammatory lesions, most often lichen sclerosus. PeINs linked to HPV, basaloid, condylomatous or condylomatous-basaloid growth affect younger men. Although clinically similar, their distinction is important, because the treatment differs with a greater risk of invasion for forms unrelated to HPV.

Minimally invasive evaluation of the clinically negative inguinal node in penile cancer: Dynamic sentinel node biopsy.

The presence of lymph node metastasis is the most important prognostic factor in penile cancer (PeCa). Due to limited sensitivity of currently available imaging modalities, invasive staging approaches remain indispensable for adequate nodal staging. As an alternative to radical inguinal lymphadenectomy and with the aim to reduce morbidity, staging strategies such as modified lymphadenectomy and dynamic sentinel node biopsy (DSNB) have been introduced. Over the years, DSNB evolved into a safe and reliable staging technique when performed in high volume centers. Recent enhancements of the procedure such as Single-photon emission computed tomography/computed tomography (SPECT/CT) and the introduction of hybrid tracers have improved pre- and intraoperative sentinel node (SN) visualization. Other technologies such as superparamagnetic iron oxide nanoparticles could have a potential future role to further refine DSNB. Future efforts should be aimed at optimizing diagnostic accuracy whilst minimizing perioperative morbidity.

[Penile carcinoma: Practical issues, from the biopsy to surgery]. / Cancer du pénis : problèmes pratiques du quotidien, de la biopsie à la chirurgie.

The management of a penile carcinoma is complex, a collaboration between radiologist, pathologist and urologist is necessary to obtain a correct staging. In this review we try to demonstrate step by step how to achieve a complete pathology report, how to manage the patient (imaging, biopsy, fresh frozen section and surgery).
