RESUMO
BACKGROUND: Radiotherapy (RT) represents an alternative treatment option for patients with T1 squamous cell carcinoma of the penis (SCCP), with proven feasibility and tolerability. However, it has never been directly compared with partial penectomy (PP) using cancer-specific mortality (CSM) as an end point. METHODS: In the Surveillance, Epidemiology, and End Results database (2000-2020), T1N0M0 SCCP patients treated with RT or PP were identified. This study relied on 1:4 propensity score-matching (PSM) for age at diagnosis, tumor stage, and tumor grade. Subsequently, cumulative incidence plots as well as multivariable competing risks regression (CRR) models addressed CSM. Additionally, the study accounted for the confounding effect of other-cause mortality (OCM). RESULTS: Of 895 patients with T1N0M0 SCCP, 55 (6.1%) underwent RT and 840 (93.9%) underwent PP. The RT and PP patients had a similar age distribution (median age, 70 vs 70 years) and more frequently harbored grade I or II tumors (67.3% vs 75.8%) as well as T1a-stage disease (67.3% vs 74.3%). After 1:4 PSM, 55 (100%) of the 55 RT patients versus 220 (26.2%) of the 840 PP patients were included in the study. The 10-year CSM derived from the cumulative incidence plots was 25.4% for RT and 14.4% for PP. In the multivariable CRR models, RT independently predicted a higher CSM than PP (hazard ratio, 1.99; 95% confidence interval, 1.05-3.80; p = 0.04). CONCLUSION: For the T1N0M0 SCCP patients treated in the community, RT was associated with nearly a twofold higher CSM than PP. Ideally, a validation study based on tertiary care institution data should be conducted to test whether this CSM disadvantage is operational only in the community or not.

BACKGROUND: Penile cancer is most prevalent in developing countries. Both the physiological and psychological consequences for the patient are critical. These consequences result from both the cancer diagnosis and the treatment's effects. OBJECTIVE: The objective of this study was to evaluate the quality of life (QoL) of patients who have undergone partial penile amputation in terms of general well-being, sexual function, and urinary function. MATERIALS AND METHODS: This retrospective observational study included 32 patients who underwent partial penile amputation. The european organisation for research and treatment of cancer core quality of life questionnaire (EORTC QLQ C-30) questionnaire was completed postoperatively. Erectile function and satisfaction were assessed retrospectively after partial penile amputation using the International Index of Erectile Function-15. RESULTS: The mean age of the patients was 54.03 ± 16.02 years. The mean scores for erectile function, orgasm, sexual desire, satisfaction, and overall satisfaction were 16.28 ± 10.83, 7.50 ± 3.30, 5.72 ± 3.35, 8.84 ± 4.77, and 9.12 ± 0.83 preoperatively, and 14.03 ± 8.61, 6.88 ± 2.97, 5.72 ± 3.35, 7.94 ± 4.09, and 7.81 ± 1.00 postoperatively. Mean erectile function, orgasm, satisfaction, and overall satisfaction were significantly decreased postoperatively compared with preoperatively. Erectile function and overall satisfaction improved more in younger years from the preoperative to the postoperative period, whereas they improved less in older years. CONCLUSION: Although partial penile amputation for penile cancer provides adequate local disease management, appropriate counseling is crucial, especially when the QoL concerns general well-being, sexual function, and urinary function.
Résumé Contexte:Le cancer du pénis est plus répandu dans les pays en développement. Les conséquences physiologiques et psychologiques pour le patient sont cruciales. Ces conséquences résultent à la fois du diagnostic de cancer et des effets du traitement.Objectif:L'objectif de cette étude était d'évaluer la qualité de vie (QdV) des patients ayant subi une amputation partielle du pénis en termes de bienêtre général, de fonction sexuelle et de fonction urinaire.Matériels et méthodes:Cette étude observationnelle rétrospective a inclus 32 patients ayant subi une amputation partielle du pénis. Le questionnaire de base sur la qualité de vie de l'organisation européenne pour la recherche et le traitement du cancer (EORTC QLQ C30) a été complété en postopératoire. La fonction érectile et la satisfaction ont été évaluées rétrospectivement après une amputation partielle du pénis à l'aide de l'indice international de la fonction érectile15.Résultats:L'âge moyen des patients était de 54,03 ± 16,02 ans. Les scores moyens pour la fonction érectile, l'orgasme, le désir sexuel, la satisfaction et la satisfaction globale étaient de 16,28 ± 10,83, 7,50 ± 3,30, 5,72 ± 3,35, 8,84 ± 4,77 et 9,12 ± 0,83 en préopératoire, et de 14,03 ± 8,61, 6,88 ± 2,97, 5,72. ± 3,35, 7,94 ± 4,09 et 7,81 ± 1,00 en postopératoire. La fonction érectile moyenne, l'orgasme, la satisfaction et la satisfaction globale étaient significativement diminués en postopératoire par rapport au préopératoire. La fonction érectile et la satisfaction globale se sont améliorées davantage dans les années plus jeunes, de la période préopératoire à la période postopératoire, alors qu'elles se sont moins améliorées dans les années plus âgées.Conclusion:Bien que l'amputation partielle du pénis pour le cancer du pénis permette une prise en charge locale adéquate de la maladie, un conseil approprié est crucial, en particulier lorsque la qualité de vie concerne le bienêtre général, la fonction sexuelle et la fonction urinaire.

BACKGROUND: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. METHODS: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. CONCLUSION: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

INTRODUCTION: Inguinal lymph nodes dissection (ILND) is recommended in patients presenting with high-risk penile (PC) or vulvar cancers (VC). Though, this surgical procedure is underused because of its anticipated morbidity. Minimally invasive approaches were proposed to minimize complications associated with open surgery. In this review, we analyze current available data exploring intra and perioperative outcomes of robot-assisted ILND (RAIL). EVIDENCE ACQUISITION: On April 9th, 2023, a literature search was conducted using the PubMed and Scopus databases. The search employed the combination of the following terms: ("robotic assisted" OR "robot-assisted" OR "robotic") AND ("inguinal lymph node dissection" OR "lymphadenectomy") AND ("penile cancer" OR "vulvar cancer"). Out of the 404 identified articles, 18 were used for the present scoping review and their results were reported according to the PRISMA statement. EVIDENCE SYNTHESIS: Data on 171 patients, ranging in age from 32 to 85 years, were obtained. Most of them (90.6%) harbored a penile squamous cell carcinoma and presented with no palpable nodes (85%). Operation time (OT) ranged between 45 and 300 min. Estimated blood loss varied from 10 to 300 mL. One single intra-operative complication was reported and one conversion to open was recorded. The lymph nodes (LNs) count spanned from 3 to 26 per groin, with 17 studies reporting a median yield >7 nodes. Hospital stay was 1-7 days, while the duration of drainage ranged from 4 to 72 days. Post-operative complications included lymphocele (22.2%; 0-100%), lymphedema (13.4%; 0-40%), cellulitis (11.1%; 0-25%), skin necrosis (8.7%; 0-15.4%). seroma (3.5%; 0-20%) and wound breakdown/wound infection (2.9%; 0-10%). Out of the included studies, 7 provided at least a 12-month follow-up, with recurrence-free rates ranging from 50% to 100% in patients affected by penile cancer and from 92% to 100% in vulvar cancer patients. CONCLUSIONS: The available evidence on RAIL for the treatment of PC and VC is limited. The approach appears to be safe and effective, as it provides an adequate lymph node yield while ensuring a minimally morbid postoperative course and a short hospital stay.

Penile melanomas (PM) are an exceedingly rare subtype of mucosal melanoma (MM), and we reviewed the clinicopathologic features and molecular profile in 8 PMs. The patient ages ranged from 46 to 78 (mean: 62.8) years with involvement on the glans (n=5; 62.5%), penile urethra (n=2; 25%), and foreskin (n=1, 12.5%). Tumor depth ranged from 1.6 to 10.0 (mean: 5.25) mm. Most of the patients underwent partial penectomy (n=6; 75%) and sentinel lymph node (LN) biopsy N=7; 87.5%). Seven patients had metastatic disease at diagnosis, 6 involving LNs and 1 the adrenal gland, and 4 died of disease with a mean follow-up period of 40.5 (2 to 95) months. Five of 7 (71%) cases identified 15 molecular alterations within KIT , CDKN2A , NF1 , PTEN , and APC (n=2 each), and NRAS , MAP3K1 , CDH1 , MSH6 , and TERT (n=1 each). Two cases were not found to harbor genetic aberrations, and 1 case failed testing. In addition, we reviewed the English literature and included 93 cases with a reported depth of invasion and follow-up. A total of 101 PMs were analyzed for prognostic parameters, and the overall survival was significantly worse in patients with LN metastasis (P=0.0008), distant metastasis (P=0.0016), and greater depth of invasion (P=0.0222) based upon T-stage. While T4 conferred substantially worse survival, the delineation of the survival curves between T2 and T3 was less clear, and combining T2+T3 disease had a strong prognostic impact ( P =0.0024). Prognostic parameters used in the staging of cutaneous melanomas may also be used in PMs. An alternative staging system expanding the inclusion criteria for T2 might provide a more accurate prognostic stratification.

OBJECTIVE: This study aimed to investigate disease-free survival (DFS) outcomes and associated prognostic factors among surgically treated penile cancer patients at Songklanagarind Hospital, Thailand, over a 20-year period. METHODS: A retrospective analysis was conducted on 208 primary penile cancer patients treated between January 2001 and December 2022. Disease-free survival was assessed using Kaplan-Meier survival curves, and Cox proportional hazard models were employed for multivariate analysis. RESULTS: All of patients (100%) were squamous cell carcinoma of penis, with 38.9% having T1 tumors, 70.7% well-differentiated tumors, and 32.6% diagnosed at stage III. The recurrence rate was 16.8%, with a mean time to recurrence of 25.9 months. Disease-free survival rates at 1, 3, and 5 years were 82.1%, 72%, and 70.2%, respectively. Median overall survival was 18.2 months, with rates at 1, 3, and 5 years at 68.7%, 44.7%, and 36.4%, respectively. Significant associations were found between disease-free survival and higher T stage, clinical chronic inflammation, delayed onset of symptoms, primary lesion location, groin node metastasis, lymphovascular invasion, and pelvic lymph node metastases. However, multivariate analysis revealed that higher primary tumor stage (T) was the only independent prognostic factor for disease-free survival. CONCLUSION: This study provides valuable insights into disease-free survival outcomes in penile cancer treatment at a single institution over an extended period. Higher pathologic T stage emerged as the sole independent prognostic factor for disease-free survival. Further validation through large-scale prospective studies is warranted.

BACKGROUND: Fasciitis ossificans is a rare subtype of nodular fasciitis, a benign soft tissue tumor with reactive characteristics. Due to its rapid growth, it is often misdiagnosed as a malignant tumor. While fasciitis ossificans commonly originates from the subcutaneous tissue and can appear throughout the body, it may also arise from extraordinary sites. CASE PRESENTATION: We report the first-ever documented case of fasciitis ossificans arising from the penis in a male patient who presented with a tumor on the glans penis. The tumor was surgically resected due to suspicion of penile cancer. Initial histopathological analysis led to a misdiagnosis of squamous cell carcinoma. However, pathological consultation ultimately confirmed the diagnosis of fasciitis ossificans of the penis originating from the glans penis by demonstrating ossification. CONCLUSION: This case underscores the importance of considering fasciitis ossificans in the differential diagnosis of soft tissue tumors, even in unusual locations such as penile soft tissue.

OBJECTIVE: Identification of superficial inguinal lymph nodes during low-risk penile cancer surgery using near-infrared (NIR) fluorescence to improve the accuracy of lymph-node dissection and reduce the incidence of missed micrometastases and complications. METHODS: Thirty-two cases were selected, which were under the criteria of < T1, and no lymph-node metastasis was found with magnetic resonance imaging (MRI) detection. Two groups were randomly divided based on the fluorescence technique, the indocyanine green (ICG) group and the non-ICG group. In the ICG group, the ICG preparation was subcutaneously injected into the edge of the penile tumor 10 min before surgery, and the near-infrared fluorescence imager was used for observation. After the lymph nodes were visualized, the superficial inguinal lymph nodes were removed first, and then, the penis surgery was performed. The non-ICG group underwent superficial inguinal lymph-node dissection and penile surgery. RESULTS: Among the 16 patients in the ICG group, we obtained 11 lymph-node specimens using grayscale values of images (4.13 ± 0.72 vs. 3.00 ± 0.82 P = 0.003) along with shorter postoperative healing time (7.31 ± 1.08 vs. 8.88 ± 2.43 P = 0.025), and less lymphatic leakage (0 vs. 5 P = 0.04) than the 16 patients in the non-ICG group. Out of 11, 3 lymph nodes that are excised were further grouped into fluorescent and non-fluorescent regions (G1/G2) and found to be metastasized. CONCLUSION: Near-infrared fluorescence-assisted superficial inguinal lymph-node dissection in penile carcinoma is accurate and effective, and could reduce surgical complications.

BACKGROUND: Penile squamous cell carcinoma (PSCC) is a rare malignancy that may be cured in cases of local disease by resection of the primary tumor. Risk factors and patterns of local recurrence (LR) have not been well described in cases requiring partial or radical penectomy. In this study, we evaluated risk factors for LR and the impact of frozen and final margin assessment. MATERIALS AND METHODS: We evaluated 119 patients with PSCC who had undergone partial or radical penectomy from 2007 to 2023. Data regarding clinical and pathologic features were collected by retrospective chart review. The primary outcome of interest was LR. Determinants of LR were analyzed by Student's t, Fisher's exact, chi-square and logistic regression analysis. Predictive statistics of frozen margin status on final margin were assessed and LR rates for subsets of frozen and final margin interaction were defined. Finally, all cases of positive margins and LR were described to highlight patterns of LR and the importance of margin status in these cases. RESULTS: There were 8 (6.7%) cases of local recurrence. There were no significant predictors of LR, although a trend toward increased LR risk was observed among those with a positive final margin. Positive final margins were found in 15 (13%) cases. Frozen margin analysis was utilized in 79 cases, of which 10 (13%) were positive. The sensitivity, specificity, positive predictive value, and negative predictive value of frozen margin status for final margins were 44%, 92%, 40%, and 93%, respectively. There were no LR among cases in which frozen margin was not sent. Analysis of all cases with positive margin and/or LR identified three subsets of patients: CIS or focally positive margin resulting in either no LR or LR managed with minimal local intervention, bulky disease in which survival is determined by response to subsequent therapy rather than local recurrence, and clinically significant local recurrence requiring continued surveillance and intervention despite negative margins. CONCLUSIONS: LR is rare, even in cases of larger, proximal tumors requiring partial or radical penectomy. In this study, no statistically significant risk factors for local recurrence were identified; however, analysis of frozen and final margins provided insight into the importance of margin status and patterns of local recurrence. When feasible, visibly intra-operative negative margins are an excellent predictor of low risk for LR, and, in cases of CIS or focally positive margins, further resection to achieve negative margins is unlikely to reduce the risk of clinically significant LR. Additionally, in cases of bulky disease, the goals of resection should be focused toward palliation and next line therapy.

OBJECTIVE: To investigate the feasibility of fluorescence molecular imaging (FMI), using cetuximab-800CW, as an intraoperative tool to determine surgical margins in penile squamous cell carcinoma (PSCC). PATIENTS AND METHODS: A total of 11 patients with PSCC received 75 mg cetuximab followed by 15 mg cetuximab-800CW 2 days before surgery. FMI of the whole excision specimen and tissue slices was performed. Fluorescence visualisation was correlated to histopathology. Based on tumour and healthy tissue regions of interest, mean fluorescence intensity was calculated for each individual patient. RESULTS: Significant differences between tumour and healthy mean fluorescence intensity were found with tumour-to-background ratios of a median (IQR) of 1.51 (0.99) and a mean (SD) of 1.51 (0.32) in the excision specimen and tissue slices, respectively. One patient showed a high relative fluorescence intensity with a signal-to-background ratio of 1.79, corresponding to a tumour-positive margin on fresh frozen sectioning. CONCLUSION: In this Phase I study we showed that cetuximab-800CW seems suitable to discriminate PSCC from background tissue. The tracer was well tolerated, and no false positive spots were seen.

OBJECTIVES: Penile carcinoma (PC) is a rare disease with considerable physical and psychological impact. To date, there is no data regarding PC prevalence and characteristics in Indonesia. This study aimed to analyze the characteristics of patients with PC in Indonesia and determine cumulative survival rates and time to disease progression. METHODS: This was a retrospective study of all patients diagnosed with PC at Cipto Mangunkusumo General Hospital from 1995 to 2014, with a minimum of 1 year follow-up. The outcomes of the study were cumulative survival rates and time-to-disease progression. RESULTS: Ninety-three subjects were recruited, with a mean age of 49.44 ± 13.62. Inguinal lymph node dissection (ILND) was performed in 49 (53%) patients. The mean survival in the ILND group was better compared to the non-ILND group (80.7 months vs. 67.1 months; p = 0.032). Time-to-progression in the ILND group was significantly longer than in the non-ILND group (71.7 months vs. 54.3 months; p = 0.022). No significant difference in survival between the total and partial penectomy (PP) groups was observed (p = 0.701). Time-to-progression in total penectomy (TP) was significantly longer than in PP (68 months vs. 56.0 months; p = 0.023). In Cox-regression analysis, after adjustment of other variables, history of ILND, higher stage of cancer, and older age were found to affect the survival of patients. CONCLUSION: ILND in PC led to better survival and reduced disease progression. The type of penectomy is only associated with progression but not survival. TP had a longer time to disease progression compared to PP.

Objective: To report outcomes of multicenter series of penile cancer patients undergoing robot-assisted video endoscopic inguinal lymph node dissection (RA-VEIL). Materials and Methods: In this retrospective analysis from 3 tertiary care centers in India, consecutive intermediate-/high-risk carcinoma penis (CaP) patients with nonpalpable inguinal lymphadenopathy and/or nonbulky (<3 cm) mobile inguinal lymphadenopathy undergoing RA-VEIL were included. Patients with matted/bulky (>3 cm) and fixed lymphadenopathy were excluded. Demographic, clinical, and intraoperative data were recorded. Perioperative complications were graded by the Clavien-Dindo classification (CDC). The International Society of Lymphology (ISL) {0-III} grading was used for the assessment of lymphedema. Incidence and pattern of recurrences were assessed on follow-up. Results: From January 1, 2011, to September 30, 2023, 115 patients (230 groins) underwent bilateral RA-VEIL for CaP. The median age of the cohort was 60 (50-69) years. Clinically palpable (either unilateral or bilateral) inguinal lymphadenopathy was seen in 54 patients (47%). The "per groin" median operative time was 120 (100-140) minutes with median lymph node yield of 12 (9-16). No complications were recorded in 87.8% groins operated, with major complications (CDC 3) seen in 2.6% groins. At a median follow-up of 13.5 months, 13 patients had documented recurrences and there were 10 cancer-related deaths. No port-site recurrences were observed. No/minimal lymphedema (ISL 0/I) was seen in 94% legs. Conclusion: RA-VEIL demonstrates safety and oncologic efficacy in penile cancer patients presenting with clinically nonpalpable and/or nonbulky inguinal lymphadenopathy, with favorable functional outcomes.

Background and Objectives: To investigate the role of preoperative albumin-to-alkaline phosphatase ratio (AAPR) in predicting pathologic node-positive (pN+) disease in penile cancer (PC) patients undergoing inguinal lymph node dissection (ILND). Materials and Methods: Clinical data of patients with squamous cell carcinoma (SCC) PC + ILND at a single high-volume institution between 2016 and 2021 were collected and retrospectively analyzed. An AAPR was obtained from preoperative blood analyses performed within 30 days from their scheduled surgery. A ROC curve analysis was used to assess AAPR cutoff, in addition to the Youden Index. Logistic regression analysis was utilized for an odds ratio (OR), 95% confidence interval (CI) calculations, and an estimate of pN+ disease. A p value < 0.05 was considered to be as statistically significant. Results: Overall, 42 PC patients were included in the study, with a mean age of 63.6 ± 12.9 years. The AAPR cut-off point value was determined to be 0.53. The ROC curve analysis reported an AUC of 0.698. On multivariable logistic regression analysis lymphovascular invasion (OR = 5.38; 95% CI: 1.47-9.93, p = 0.022), clinical node-positive disease (OR = 13.68; 95% CI: 4.37-43.90, p < 0.009), and albumin-to-alkaline phosphatase ratio ≤ 0.53 (OR = 3.61; 95% CI: 1.23-12.71, p = 0.032) were predictors of pN+ involvement. Conclusions: Preoperative AAPR may be a potentially valuable prognostic marker of pN+ disease in patients who underwent surgery for PC.

Objective: Small series and individual cases of penile soft tissue tumours are reported in the literature: these are rare tumours that represent less than 5% of all penile tumours. Methods: Penile soft tissue tumours were collected from the archive of the Department of Pathology at the Istituto Nazionale dei Tumori of Milan between January 1990 and October 2021. All available medical records were retrieved and reviewed to obtain clinical information. Results: Our series refers to the 30-year experience of highlighting the heterogeneity in the presentation and microscopic features of these rare sarcomas. 18 penile soft tissue tumours are described, 4 benign and 14 malignant. The mean age at diagnosis was 58.2 years (range 24-96 years) and 53.6 years among malignancies (range 24-89). The most frequent histotype was Kaposi's sarcoma (nr = 4) and very unusual histotypes were observed, namely low-grade fibromyxoid sarcoma, synovial sarcoma, proximal type epithelioid sarcoma and the first reported case of dedifferentiated liposarcoma of the penis. Conclusions: Among sarcomas of the genitourinary tract, tumours of the soft tissues of the penis are the rarest. Penile sarcomas can present at a young age. Kaposi's sarcoma in HIV-negative patients has a favorable outcome, while deep sarcomas have an aggressive behavior and poor prognosis.

OBJECTIVE: To evaluate perioperative and oncologic outcomes of a cohort of clinically node negative high-risk penile cancer patients undergoing robotic assisted inguinal lymph node dissection (RAIL) compared to patients undergoing open superficial inguinal lymph node dissection (OSILND). PATIENTS AND METHODS: We retrospectively reviewed the clinical characteristics and outcomes of clinically node negative high-risk penile cancer patients undergoing RAIL at MDACC from 2013-2019. We sought to compare this to a contemporary open cohort of clinically node negative patients treated from 1999 to 2019 at MDACC and Moffit Cancer Center (MCC) with an OSILND. Descriptive statistics were used to characterize the study cohorts. Comparison analysis between operative variables was performed using Fisher's exact test and Wilcoxon's rank-sum test. The Kaplan-Meier method was used to estimate survival endpoints. RESULTS: There were 24 patients in the RAIL cohort, and 35 in the OSILND cohort. Among the surgical variables, operative time (348.5 minutes vs. 239.0 minutes, P < 0.01) and the duration of operative drain (37 vs. 22 days Pâ¯=â¯0.017) were both significantly longer in the RAIL cohort. Complication incidences were similar for both cohorts (34.3% for OSILND vs. 33.3% for RAIL), with wound complications making up 33% of all complications for RAIL and 31% of complications for OSILND. No inguinal recurrences were noted in either cohort. The median follow-up was 40 months for RAIL and 33 months for OSILND. CONCLUSIONS: We observed similar complication rates and surgical variable outcomes in our analysis apart from operative time and operative drain duration. Oncological outcomes were similar between the two cohorts. RAIL was a reliable staging and potentially therapeutic procedure among clinically node negative patients with penile squamous cell carcinoma with comparable outcomes to an OSILND cohort.

BACKGROUND: Radical inguinal lymph node dissection (rILND) is the most available treatment to cure penile cancer (PC) with limited inguinal-confined disease. However, guidelines regarding acceptable boundaries of rILND are controversial, and consensus is lacking. The authors aimed to standardize the surgical boundaries of rILND with definite pathological evidence and explore the distribution pattern of inguinal lymph nodes (ILNs) in PC. METHODS: A total of 414 PC patients from two centers who underwent rILND were enrolled. The ILN distribution was divided into seven zones anatomically for pathological examination. Student's t test and Kaplan-Meier survival analysis were used. RESULTS: ILNs displayed a funnel-shaped distribution with high density in superior regions. ILNs and metastatic nodes are present anywhere within the radical boundaries. Positive ILNs were mainly concentrated in zone I (51.7%) and zone II (41.3%), but there were 8.7% and 12.3% in inferior zones V and VI, respectively, and 7.1% in the deep ILNs. More importantly, a single positive ILN and first-station positive zone was detected in all seven regions. Single positive ILNs were located in zones I through VI in 40.4%, 23.6%, 6.7%, 18.0%, 4.5%, and 1.1%, respectively, and 5.6% presented deep ILN metastasis directly. CONCLUSIONS: The authors established a detailed ILN distribution map and displayed lymphatic drainage patterns with definite pathological evidence using a large cohort of PC patients. Single positive ILNs and first-station metastatic zones were observed in any region, even directly with deep ILN metastasis. Only rILND can ensure tumor-free resection without the omission of positive nodes.

INTRODUCTION: This study investigated the efficacy and safety of neoadjuvant chemotherapy for locally advance penile squamous cell carcinoma for which current evidence is lacking. METHODS: Included patients had locally advanced penile squamous cell carcinoma with clinical lymph node metastasis treated with at least 1 dose of neoadjuvant chemotherapy prior to planned consolidative lymphadenectomy. Objective response rates were assessed using Response Evaluation Criteria in Solid Tumors v1.1. The primary and secondary outcomes were overall survival and progression-free survival, estimated by the Kaplan-Meier method. Treatment-related adverse events were graded per the Common Terminology Criteria for Adverse Events v5.0. RESULTS: A total of 209 patients received neoadjuvant chemotherapy for locally advanced and clinically node-positive penile squamous cell carcinoma. The study population consisted of 7% of patients with stage II disease, 48% with stage III, and 45% with stage IV. Grade 2 treatment-related adverse events occurred in 35 (17%) patients, and no treatment-related mortality was observed. Of the patients, 201 (97%) completed planned consolidative lymphadenectomy. During follow-up, 106 (52.7%) patients expired, with a median overall survival of 37.0 months (95% confidence interval [CI] = 23.8 to 50.1 months) and median progression-free survival of 26.0 months (95% CI = 11.7 to 40.2 months). Objective response rate was 57.2%, with 87 (43.2%) having partial response and 28 (13.9%) having a complete response. Patients with objective response to neoadjuvant chemotherapy had a longer median overall survival (73.0 vs 17.0 months, P < .01) compared with those who did not. The lymph node pathologic complete response rate was 24.8% in the cohort. CONCLUSION: Neoadjuvant chemotherapy with lymphadenectomy for locally advanced penile squamous cell carcinoma is well tolerated and active to reduce the disease burden and improve long-term survival outcomes.
