Background and AimsThe current guidelines for the treatment of penile cancer patients with clinically non-invasive normal inguinal lymph nodes are still broad, so the purpose of this study is to determine which patients are suitable for lymph node dissection (LND).MethodsHistologically confirmed penile cancer patients (primary site labeled as C60.9-Penis) from 2004 to 2016 in the Surveillance, Epidemiology, and Results database were included in this analysis. Univariate and multivariate Cox regression analyses were applied to determine an overall estimate of LND on overall survival and cancer-specific survival. A 1:1 propensity matching analysis (PSM) was applied to enroll balanced baseline cohort, and further Kaplan–Meier (KM) survival analysis was used to get more reliable results.ResultsOut of 4,458 histologically confirmed penile cancer patients with complete follow-up information, 1,052 patients were finally enrolled in this analysis. Age, pathological grade, T stage, and LND were identified as significant predictors for overall survival (OS) in the univariate Cox analysis. In the multivariate Cox regression, age, pathological grade, T stage, and LND were found significant. The same results were also found in the univariate and multivariate Cox regression analyses for cancer-specific survival (CSS). After the successful PSM, further KM analysis revealed that LND could bring significant OS and CSS benefits for T3T4 patients without lymph node metastasis.ConclusionLymph node dissection may bring survival benefits for penile cancer patients without preoperatively detectable lymph node metastasis, especially for T3T4 stage patients. Further randomized control trial is needed.

Background: The aim of this study is to determine the necessary extent of penile lymph node dissection (PLND) in penile cancer patients with inguinal lymph node extracapsular extension (ILN-ENE).Methods: Penile cancer patients who underwent PLND in 15 centers from January 2006 to April 2020 were retrospectively analyzed. PLND was performed in patients with ILN-ENE.Results: Sixty-two patients with ILN-ENE were included in the analysis. A total of 51.6% (32/62) of the patients were confirmed to have pelvic lymph node metastasis (PLNM), and 31.3% (10/32) of patients were confirmed to have multiple PLNMs. Of the patients with metastases, 59.4% (19/32) had bilateral inguinal lymph node metastasis (ILNM). According to the anatomical structure, 71.9% (23/32) of the patients had PLNM in the external iliac region, and 56.2% (18/32) had PLNM in the obturator region. Among those with oligo-PLNM, 65.1% (28/43) of the patients had PLNM in the external iliac region and 38.9% (15/43) had PLNM in the obturator region. A significant overall survival difference was observed between patients with the bilateral ILNM and unilateral ILNM (36-month: 21.2 vs. 53.7%, respectively, P = 0.023). Patients with bilateral ILNM had relatively poor metastasis-free survival compared with unilateral ILNM (36-month: 33.0 vs. 13.9%, respectively, P = 0.051).Conclusions: The external iliac and obturator region were the most commonly affected regions in patients with ILN-ENE, and these regions were the only affected regions in patients with oligo-PLNM. Patients with bilateral ILNM had a high risk of PLNM and worse survival.

Introduction: Penile cancer is a moderately common malignancy in developing countries. Metastasis to regional lymph nodes is an essential factor in a patient’s prognosis, as its occurrence predicts poor patient prognosis. As micro-metastasis occurs in more than 25% of cases, the need for more accessible diagnostic tools is necessary. Ki-67 is commonly used as a marker of proliferation associated with tumor grade and lymph node metastasis. Methods: Samples were taken from penile cancer patients between 2013 to 2018, in the form of formalin-fixed paraffin-embedded (FFPE) blocks were analyzed. Patient demographic data, current and pre-cancer condition, cancer staging, outcomes, and other results of adjuncts and treatment modalities were obtained from medical records. Immunohistochemistry analysis was carried out on FFPE preparations. Under 20% of nuclei stained was considered as low-expression and more than 20% of nuclei stained was considered as Ki-67 over-expression. Data processing and analysis were carried out using SPSS software.  Results: In total, 48 FFPE samples were analyzed, with a mean patient age of 50.79 (±9.51 SD). For all patients, the type of pathology was squamous cell carcinoma. Node metastasis was positive in 34 patients (70.8%) and negative in 14 patients (29.2%). Statistical analysis was carried out using the Chi-Square test, resulting in a significant correlation between the expression of Ki-67 and lymph node metastasis in penile squamous cell carcinoma (p=0.045). Conclusion: Over-expression of Ki-67 were found in penile cancer patients with lymph node metastasis. Therefore, Ki-67 might be useful in predicting lymph node metastasis in penile cancer patients.
