Cancers (Basel) 2024; 16:2935. [PMID: 39272796 PMCID: PMC11394048 DOI: 10.3390/cancers16172935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2024] [Revised: 08/19/2024] [Accepted: 08/21/2024] [Indexed: 09/15/2024] Open
Abstract
The diagnosis of occult inguinal lymph node metastasis in clinically node-negative invasive penile squamous cell carcinoma (PSCC) has remained a challenge, with substantial perioperative complications. The recent refinements in the technique of dynamic sentinel lymph node biopsy (DSLNB) demonstrated high diagnostic accuracy with considerably lower morbidity compared to conventional open modified/superficial inguinal lymph node dissection (ILND). Although DSLNB, if available, has been endorsed as the preferred method for nodal staging in patients with invasive PSCC and no palpable inguinal lymphadenopathy in the recent penile cancer guidelines, its utilization has been quite limited so far. Laparoscopic and robotic-assisted ILND have emerged as alternatives for nodal staging in this patient population and are shown to improve the rate of wound infections and postoperative pain. For management of nodal metastasis in patients with clinically palpable inguinal lymph nodes, minimally invasive ILND has shown promising results as well. Nonetheless, given the rarity of PSCC and the absence of prospective studies and clinical trials, nodal staging and treatment of nodal metastasis in clinical practice will likely continue to vary across the medical centers in the following years. In this review, we first summarize the evolution of DSLNB and minimally invasive ILND and discuss the advantages and drawbacks of each management strategy. We further discuss the remaining challenges and future perspectives in the management of inguinal lymph nodes in patients with PSCC.

Clin Genitourin Cancer 2024; 22:102117. [PMID: 38820999 DOI: 10.1016/j.clgc.2024.102117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 05/05/2024] [Accepted: 05/06/2024] [Indexed: 06/02/2024]
Abstract
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.

Abstract
INTRODUCTION The European Association of Urology (EAU) and the American Society of Clinical Oncology (ASCO) recently issued updated guidelines on penile cancer, emphasising dynamic sentinel node biopsy (DSNB) as the preferred method for surgical staging among patients with invasive penile tumours and no palpable inguinal lymphadenopathy. This paper outlines the rationale behind this new recommendation and describes remaining challenges, as well as strategies for promoting DSNB worldwide. MAIN TEXT DSNB offers high diagnostic accuracy with the lowest postoperative complications compared to open or minimally invasive inguinal lymph node dissection (ILND), prompting its preference in the new guidelines. Nevertheless, despite its advantages, there are challenges hampering the widespread adoption of DSNB. This includes the false-negative rate associated with DSNB and the potential negative impact on patient outcome. To address this issue, improvements should be made in several areas, including refining the timing and interpretation of the lymphoscintigraphy and the single photon emission computed tomography/computed tomography images. In addition, the quantity of tracer employed and choice of the injection site for the radiopharmaceutical should be optimised. Finally, limiting the removal of nodes without tracer activity during surgery may help minimise complication rates. CONCLUSION Over the years, DSNB has evolved significantly, related to the dedicated efforts and innovations in nuclear medicine and subsequent clinical studies validating its efficacy. It is now strongly recommended for surgical staging among selected penile cancer patients. To optimise DSNB further, multidisciplinary collaborative research is required to improve SN identification for better diagnostic accuracy and fewer complications.

Abstract
BACKGROUND Lymphatic metastasis is the major challenge in the treatment of penile cancer. The prognosis of individuals with lymphatic metastasis is extremely poor. Therefore, early identification of disease progression and lymphatic metastasis is an urgent task for researchers in penile cancer worldwide. METHODS In this study, using single-cell RNA sequencing, an immune landscape was established for the cancer ecosystem based on 46,861 cells from six patients with penile cancer (four with lymphatic metastasis [stage IV] and two without lymphatic metastasis [stage I]). Using bulk RNA sequencing, the discrepancy between the cancers and their respective metastatic lymph nodes was depicted based on seven patients with penile cancer. RESULTS The interaction between epithelial cells, fibroblasts, and endothelial cells, and the functional cooperation among invasion, epithelial-mesenchymal transition, and angiogenesis were found to be important landscapes in the penile cancer ecosystem, playing important roles in progression of cancer and lymph node metastasis. CONCLUSIONS This study is the first to investigate the altered tumor microenvironment heterogeneity of penile cancer as it evolves from non-lymphatic to lymphatic metastasis and provides insights into the mechanisms underlying malignant progression, the premetastatic niche, and lymphatic metastasis in penile cancer.

Abstract
CONTEXT Lymphadenectomy during surgery for genitourinary malignancies has varying benefits. OBJECTIVE To review contemporary evidence on lymph node dissection in genitourinary cancers. EVIDENCE ACQUISITION We performed a collaborative review to summarize current evidence supporting lymph node dissection in urothelial, prostate, kidney, penile, and testis cancers. We present the evidence on patient selection and recommended dissection templates, and highlight knowledge gaps and ongoing areas of investigation. EVIDENCE SYNTHESIS Lymph node dissection remains the reference standard for lymph node staging. Pathologic nodal stage informs prognosis and guides adjuvant treatment. Appropriate template and patient selection are paramount to optimize outcomes and capitalize on the selective therapeutic benefits. CONCLUSIONS Accurate staging with lymphadenectomy is contingent on appropriate template selection. The cumulative benefit will depend on judicious patient selection. PATIENT SUMMARY We performed a collaborative review by a diverse group of experts in urology. We reviewed current evidence on lymph node dissection.

Abstract
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.

Abstract
OBJECTIVES To investigate the safety and efficacy of indocyanine green (ICG) fluorescence-guided inguinal lymph node dissection (ILND) in patients with penile cancer. PATIENTS AND METHODS A prospective, single-blind, randomised controlled clinical trial (ChiCTR2100044584) was performed among patients with penile caner who underwent bilateral modified ILND at four centres in China between 1 April 2021 and 30 June 2022. Patients aged 18-80 years and diagnosed with squamous cell carcinomas were included. Each enrolled patient was randomly assigned to either ICG fluorescence-guided ILND by a laparoscopic or robot-assisted approach in one groin, with non-ICG fluorescence-guided ILND in the other groin acting as a control. The primary outcome was the number of retrieved ILNs. Secondary outcomes included complications according to the Clavien-Dindo classification and the ILN non-compliance (inadequate removal of ILNs) rate. RESULTS A total of 45 patients were included in the intention-to-treat (ITT) analysis, and the 42 who completed the entire study were included in the per protocol (PP) analysis. There were no ICG-related complications in any of the patients. The results of the ITT and PP analyses indicated that the total number of unilateral ILNs retrieved was higher on the ICG side than on the non-ICG side (mean 13 vs 9 ILNs, difference 4 ILNs [95% CI 2.7-4.4], P = 0.007), and the number of unilateral deep and superficial ILNs was higher on the ICG side. Furthermore, the LN non-compliance rate was lower on the ICG side than on the non-ICG side. Additionally, there was no significant difference in local complications in the groins between the two sides (P > 0.05). CONCLUSION An ICG fluorescence-guided ILND was safe for patients with penile cancer. This procedure can improve the number of ILNs retrieved and reduce the LN non-compliance rate without increased complications. ICG fluorescence-guided ILND is beneficial and recommended for selected patients with penile cancer.

Abstract
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.

Robotic or open superficial inguinal lymph node dissection as staging procedures for clinically node negative high risk penile cancer. Urol Oncol 2024; 42:120.e1-120.e9. [PMID: 38388244 DOI: 10.1016/j.urolonc.2024.01.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/27/2024] [Accepted: 01/29/2024] [Indexed: 02/24/2024]
Abstract
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 P = 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.

Abstract
CONTEXT Lymph node (LN) involvement in penile cancer is associated with poor survival. Early diagnosis and management significantly impact survival, with multimodal treatment approaches often considered in advanced disease. OBJECTIVE To assess the clinical effectiveness of treatment options available for the management of inguinal and pelvic lymphadenopathy in men with penile cancer. EVIDENCE ACQUISITION EMBASE, MEDLINE, the Cochrane Database of Systematic Reviews, and other databases were searched from 1990 to July 2022. Randomised controlled trials (RCTs), nonrandomised comparative studies (NRCSs), and case series (CSs) were included. EVIDENCE SYNTHESIS We identified 107 studies, involving 9582 patients from two RCTs, 28 NRCSs, and 77 CSs. The quality of evidence is considered poor. Surgery is the mainstay of LN disease management, with early inguinal LN dissection (ILND) associated with better outcomes. Videoendoscopic ILND may offer comparable survival outcomes to open ILND with lower wound-related morbidity. Ipsilateral pelvic LN dissection (PLND) in N2-3 cases improves overall survival in comparison to no pelvic surgery. Neoadjuvant chemotherapy in N2-3 disease showed a pathological complete response rate of 13% and an objective response rate of 51%. Adjuvant radiotherapy may benefit pN2-3 but not pN1 disease. Adjuvant chemoradiotherapy may provide a small survival benefit in N3 disease. Adjuvant radiotherapy and chemotherapy improve outcomes after PLND for pelvic LN metastases. CONCLUSIONS Early LND improves survival in nodal disease in penile cancer. Multimodal treatments may provide additional benefit in pN2-3 cases; however, data are limited. Therefore, individualised management of patients with nodal disease should be discussed in a multidisciplinary team setting. PATIENT SUMMARY Spread of penile cancer to the lymph nodes is best managed with surgery, which improves survival and has curative potential. Supplementary treatment, including the use of chemotherapy and/or radiotherapy, may further improve survival in advanced disease. Patients with penile cancer with lymph node involvement should be treated by a multidisciplinary team.

Real world data of recurrent and survival rates of penile cancer patients in Songklanagarind hospital: Tumor stage as a predictor for disease-free survival. Int J Urol 2024; 31:144-153.

Abstract
OBJECTIVE This study investigated disease-free survival and oncological outcomes in penile cancer patients treated surgically at a high-volume center and identified the prognostic factors for disease-free survival. METHODS A retrospective analysis was conducted on primary penile cancer patients diagnosed and treated at Songklanagarind Hospital, Thailand, between January 2001 and December 2021. Disease-free survival (DFS) was assessed using Kaplan-Meier survival curves, and Cox proportional hazard models were used for multivariate analysis. RESULTS The study included 188 patients with primary penile cancer. The majority (98.4%) were uncircumcised. Tumor staging revealed 40.6% with T1 tumors, 72.9% with well-differentiated tumors, and 23.5% diagnosed at stage IIIA. The recurrence rate was 19.1%, with a mean time to recurrence of 25.9 months. Disease-free survival rates at 1, 3, and 5 years were 81.1%, 70.9%, and 70.9%, respectively. Median overall survival was 16.43 months, with survival rates at 1, 3, and 5 years at 67.7%, 42.7%, and 35.4%, respectively. Cox proportional hazard models showed significant associations between disease-free survival and a higher T stage, a high level of CRP (>15 mg/L), delayed onset of symptoms, primary lesion location, groin node metastasis, lymphovascular invasion, and pelvic lymph node metastases. However, multivariate analysis revealed that a higher primary tumor stage (T) was the only independent prognostic factor for disease-free survival. CONCLUSION This study presents one of the largest cohorts investigating disease-free survival outcomes in penile cancer treatment at a single institution over a prolonged period. A higher pathologic T stage is a significant prognostic factor for disease-free survival. Further large-scale prospective studies are needed for validation.

Abstract
BACKGROUND Penile cancer (PeCa) represents a diagnostic and therapeutic challenge given the low patient volume, which may result in inadequate physician expertise and poor guideline adherence. Since 2015, we have developed a specific care pathway for PeCa in our tertiary referral center. OBJECTIVE To evaluate the impact of a dedicated PeCa care pathway on patient management, the adequacy of pathological reporting, and oncological outcomes. DESIGN, SETTING, AND PARTICIPANTS We retrospectively queried our institutional registry (S-66482) to identify patients who were surgically treated for PeCa between January 1989 and April 2022. The patient numbers were evaluated within a broader national context. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS We compared patient, surgery, tumor, and pathological data before and after 2015. Kaplan-Meier analysis was used to compare local and regional recurrence rates and cancer-specific survival (CSS). RESULTS AND LIMITATIONS Overall, 313 patients were included, of whom 204 (65.1%) were surgically treated after 2015. The median number of patients treated yearly was significantly higher after 2015 (26 vs 5; p < 0.01). Patients treated after 2015 more frequently had no palpable lymph nodes at diagnosis, despite similar primary tumor stage. After adoption of the PeCa care pathway, organ-sparing surgery (OSS) was more commonly performed (79.9% vs 57.8%; p < 0.01) despite local staging being similar and without observing a significant increase in positive margins. Surgical staging in patients with European Association of Urology intermediate- or high-risk tumors was conducted more frequently after 2015 (90% vs 41%; p < 0.01). Pathology reporting was standardized, and there was more frequent reporting of p16 staining status (81.4% vs 8.3%; p < 0.01), lymphovascular invasion (93.8% vs 44.3%; p < 0.01), and perineural invasion (92.4% vs 44.3%; p < 0.01) following implementation. CONCLUSIONS Implementation of a standardized care pathway for PeCa resulted in higher rates of OSS and pathological nodal staging and more complete pathology reports. Considering that these changes were associated with an increase in the number of patients treated, academic-driven centralization may play a role in optimizing the management of these patients. PATIENT SUMMARY We evaluated the impact of a care pathway for patients with penile cancer on patient management, the completeness of pathology reporting, and cancer control. We found that implementation of this pathway was associated with an increase in the number of patients treated, higher rates of organ-sparing surgery and lymph node staging, and more complete pathology reports. Centralization of care may play a role in optimizing the management of penile cancer.

Abstract
Purpose The pathophysiology of penis extends to erectile dysfunction (ED) to conditions including sexually transmitted diseases (STDs) and cancer. To date, there has been little research evaluating vascular drainage from the penis. We aimed to evaluate penile blood flow in vivo and analyze its possible relationship with the lymphatic maker. Materials and Methods We established an in vivo system designed to assess the dynamic blood outflow from the corpus cavernosum (CC) by dye injection. To analyze lymphatic characteristics in the CC, the expression of Lyve-1, the key lymphatic endothelium marker, was examined by the in vitro system and lipopolysaccharide (LPS) injection to mimic the inflammatory conditions. Results A novel cavernography methods enable high-resolution morphological and functional blood drainage analysis. The expression of Lyve-1 was detected along the sinusoids. Furthermore, its prominent expression was also observed after penile LPS injection and in the erectile condition. Conclusions The current in vivo system will potentially contribute to the assessment of penile pathology from a novel viewpoint. In addition, current analyses revealed inducible Lyve-1 expression for LPS injection and the erection state, which requires further analyses on penile lymphatic system.

Abstract
BACKGROUND Penile cancer accounts for less than 1% of male cancers in the United States. Localized disease, particularly T1 tumors are potentially curable with local therapy. We present the racial differences in survival outcomes for T1, penile cancer from the SEER database. METHODS From 2004 to 2016 all men with T1, N0, M0 penile cancer in the SEER-18 database were included. Kaplan-Meier analysis and multivariable Cox-Regression analysis were conducted to investigate prognostic variables for cancer specific survival (CSS). RESULTS A total of 4,406 men were identified with penile cancer; 1,941 men had T1 disease. The Kaplan-Meier (KM) analysis showed those with primary site surgery had better 5-year CSS compared to those without primary site surgery (P <.0001) and a significant difference in CSS based on race (P= 0.0078). On multivariable analysis, Hispanic individuals had worse CSS (HR 1.92; P = 0.0057) compared to the White men. Black men were also found to have a poor CSS however this was not statistically significant (HR 1.53, P = 0.118). Men with penile cancer who had either penectomy (HR 0.45; P = 0.006) or penile preservation surgery (HR 0.25; P< 0.001) had improved CSS. CONCLUSION Racial disparities in CSS exist among men with in early-stage penile cancer. KM analysis showed significant differences in CSS by race and in those receiving primary site surgery. On multivariable analysis, the CSS is worse in Hispanic compared to White men. There is a trend towards worse CSS in Black men however this was not statistically significant.

Abstract
The sentinel lymph node is the first lymph node from the primary tumor. Sentinel lymph node biopsy (SLNB) is a surgical procedure that can detect occult nodal metastasis with relatively low morbidity. It may also have a therapeutic effect via regional disease control. The Multicenter Selective Lymphadenectomy-I (MSLT-I) trial revealed a prognostic benefit from SLNB in melanoma patients. However, it remains unclear whether there is a prognostic benefit from SLNB in patients with nonmelanoma skin cancer owing to a lack of randomized prospective studies. Nevertheless, SLNB provides important information about nodal status, which is one of the strongest factors to predict prognosis and may guide additional nodal treatment. Currently, SLNB is widely used in the management of not only patients with melanoma but also those with nonmelanoma skin cancer. However, the utilization and outcomes of SLNB differ among skin cancers. In addition, SLNB is not recommended for routine use in all patients with skin cancer. In this review, we provide a summary of the role of SLNB and of the indications for SLNB in each skin cancer based on previously published articles.

Abstract
Nodal metastasis is a strong prognostic indicator in carcinoma penis, with 25% difference in 5-year cancer-specific survival among node negative and node positive patients. This study aims to assess efficacy of SLNB in identifying occult nodal metastasis (seen in 20-25% of cases), thus avoiding morbidity of prophylactic groin dissection in rest. Study was conducted between June 2016 and December 2019 on 42 patients (84 groins). Primary outcomes assessed were sensitivity, specificity, false negative rates, positive predictive value, and negative predictive value of sentinel lymph node biopsy (SLNB) compared to superficial inguinal node dissection (SIND). Secondary outcomes were to know prevalence of nodal metastasis, sensitivity, specificity, false negative rates, positive predictive value (PPV), negative predictive value (NPV) of frozen section study, and ultrasonography (USG) compared to histopathological examination (HPE) and to evaluate false negative results of fine needle aspiration cytology (FNAC). Patients with impalpable inguinal nodes were subjected to USG and FNAC of suspicious nodes. Only those with non-suspicious USG/negative FNAC were included. Patients who were node positive, had prior chemotherapy/radiotherapy/prior groin surgery, or medically unfit for surgery were excluded. Dual-dye technique was used to identify sentinel node. Superficial inguinal dissection was done in all cases and both specimens were subject to frozen section. If ≥ 2 nodes were involved on frozen section, ilioinguinal dissection was done. SLNB had sensitivity, specificity, PPV, NPV, and accuracy of 100%, respectively. There were no false negative results of frozen section study among 168 specimens. Ultrasonography had sensitivity of 50%, specificity of 48.75%, PPV of 4.65%, NPV of 95.12%, and accuracy of 48.81%. We had 2 false negative results of FNAC. Sentinel node biopsy with frozen section study when done in properly selected cases using dual-dye technique in high volume centers by experienced professionals is a very reliable tool in establishing the nodal status, thereby facilitating need directed treatment, thus prevent either over/under treatment.

Abstract
PURPOSE To assess the long-term risks of infectious and thromboembolic events following inguinal (ILND) and pelvic (PLND) lymph node dissection in men with penile cancer. MATERIAL AND METHODS A total of 364 men subjected to ILND with or without PLND for penile cancer between 2000 and 2012 were identified in the Swedish National Penile Cancer Register. Each patient was matched based on age and county of residence with six penile cancer-free men. The Swedish Cancer Register and other population-based registers were used to retrieve information on treatment and hospitalisation for selected infectious and thromboembolic events. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated using Cox proportional hazard models with multiple imputation. RESULTS The risk of infectious events remained increased for more than five years postoperatively in men with penile cancer compared with matched controls. The palpable nodal disease was the only predictor of these events, with risk increasing with the cN stage. The HR at one, three and five years and six months postoperatively was 8.60 (95% CI 5.16-14.34), 4.02 (95% CI 2.65-6.09) and 1.93 (95% CI 1.11-3.38), respectively. An increased risk of thromboembolic events persisted for three years postoperatively. The HR at one and three years postoperatively was 13.51 (95% CI 6.53-27.93) and 2.12 (95% CI 1.07-4.20). The results correspond well with the over-prescription of anticoagulants observed during this period. An association with bulky disease (cN3) was observed. CONCLUSIONS Lymph node dissection for penile cancer is associated with an increased risk of infectious and thromboembolic events. The findings of this population-based study show that the risks of these events remain increased more than five years for infectious and three years for thromboembolic events. Improved awareness of long-term complications following ILND is of importance both among patients and care givers to ensure early detection and treatment.

Abstract
OBJECTIVES To compare differences of operative outcomes, post-operative complications and survival outcomes between open and laparoscopic cases in a multicenter study. METHODS This was a retrospective cohort study performed at three European centers from September 2011 to January 2019. The surgeon decision to perform open inguinal lymphadenectomy (OIL) or video endoscopic inguinal lymphadenectomy (VEIL) was done in each hospital after patient counselling. Inclusion criteria regarded a minimum follow-up of 9 months since the inguinal lymphadenectomy. RESULTS A total of 55 patients with proven squamous cell penile cancer underwent inguinal lymphadenectomy. 26 of them underwent OIL, while 29 patients underwent VEIL. For the OIL and VEIL groups, the mean operative time was 2.5 vs. 3.4 h (p=0.129), respectively. Hospital stays were lower in the VEIL group with 4 vs. 8 days in OIL patients (p=0.053) while number of days requiring drains to remain in situ was 3 vs. 6 days (p=0.024). The VEIL group reported a lower incidence of major complications compared to the OIL group (2 vs. 17%, p=0.0067) while minor complications were comparable in both groups. In a median follow-up period of 60 months, the overall survival was 65.5 and 84.6% in OIL and VEIL groups, respectively (p=0.105). CONCLUSIONS VEIL is comparable to OIL regarding safety, overall survival and post-operative outcomes.

Abstract
PURPOSE In 95% of cases, penile cancer is a squamous cell carcinoma whose specificity is lymphatic spread with the inguinal lymph nodes as the first relay route. Inguinal lymph node dissection is a primordial part of the treatment. The objective was to assess the oncological results of inguinal lymph node dissection in penile cancer at our centre. METHODS We retrospectively included all patients having undergone inguinal lymph node dissection at our centre between 1 January 2004 and 1 January 2020 for the treatment of penile cancer. Patients for whom lymphadenopathy was palliative were excluded. Depending on indications, the procedures consisted in either dynamic sentinel node biopsy, modified lymphadenectomy or radical lymphadenectomy. All cancers were reclassified using the 2016 TNM classification system. Survival was analysed according to the Kaplan-Meier method. RESULTS 242 inguinal lymph node dissections were performed in 122 patients. There were 71 pN0 (58%), 9 pN1 (7%), 4 pN2 (3%) and 38 pN3 (31%). Mean follow-up was 51 ± 45 months. The 3-year recurrence-free survival rate was 76% in pN0 patients and 17% in pN3 patients. The 5-year specific and overall survival rates were, respectively, 82% and 73% for pN0 stages, and 14% and 17% for pN3 stages. Extracapsular extension on an inguinal lymphadenopathy appeared as a highly negative prognostic factor. CONCLUSION Inguinal lymph node dissection is essential in the treatment of penile cancer. Recurrence-free, specific and overall survival are closely linked to the lymph node stage. Extracapsular extension and pelvic lymph node invasion are highly negative prognostic factors.

Abstract
ObjectiveInguinal lymph node metastasis (ILNM) is significantly associated with poor prognosis in patients with squamous cell carcinoma of the penis (SCCP). Patient prognosis could be improved if the probability of ILNM incidence could be accurately predicted at an early stage. We developed a predictive model based on machine learning combined with big data to achieve this.MethodsData of patients diagnosed with SCCP were obtained from the Surveillance, Epidemiology, and End Results Program Research Data. By combing variables that represented the patients' clinical characteristics, we applied five machine learning algorithms to create predictive models based on logistic regression, eXtreme Gradient Boosting, Random Forest, Support Vector Machine, and k-Nearest Neighbor. Model performance was evaluated by ten-fold cross-validation receiver operating characteristic curves, which were used to calculate the area under the curve of the five models for predictive accuracy. Decision curve analysis was conducted to estimate the clinical utility of the models. An external validation cohort of 74 SCCP patients was selected from the Affiliated Hospital of Xuzhou Medical University (February 2008 to March 2021).ResultsA total of 1,056 patients with SCCP from the SEER database were enrolled as the training cohort, of which 164 (15.5%) developed early-stage ILNM. In the external validation cohort, 16.2% of patients developed early-stage ILNM. Multivariate logistic regression showed that tumor grade, inguinal lymph node dissection, radiotherapy, and chemotherapy were independent predictors of early-stage ILNM risk. The model based on the eXtreme Gradient Boosting algorithm showed stable and efficient prediction performance in both the training and external validation groups.ConclusionThe ML model based on the XGB algorithm has high predictive effectiveness and may be used to predict early-stage ILNM risk in SCCP patients. Therefore, it may show promise in clinical decision-making.

Abstract
CONTEXT Penile cancer is a rare disease but has a significant impact on quality of life. Its incidence is increasing, so it is important to include new and relevant evidence in clinical practice guidelines. OBJECTIVE To provide a collaborative guideline that offers worldwide physician and patient guidance for the management of penile cancer. EVIDENCE ACQUISITION Comprehensive literature searches were performed for each section topic. In addition, three systematic reviews were conducted. Levels of evidence were assessed, and a strength rating for each recommendation was assigned according to the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) methodology. EVIDENCE SYNTHESIS Penile cancer is a rare disease but its global incidence is increasing. Human papillomavirus (HPV) is the main risk factor for penile cancer and pathology should include an assessment of HPV status. The main aim of primary tumour treatment is complete tumour eradication, which has to be balanced against optimal organ preservation without compromising oncological control. Early detection and treatment of lymph node (LN) metastasis is the main determinant of survival. Surgical LN staging with sentinel node biopsy is recommended for patients with a high-risk (≥pT1b) tumour with cN0 status. While (inguinal) LN dissection remains the standard for node-positive disease, multimodal treatment is needed in patients with advanced disease. Owing to a lack of controlled trials and large series, the levels of evidence and grades of recommendation are low in comparison to those for more common diseases. CONCLUSIONS This collaborative penile cancer guideline provides updated information on the diagnosis and treatment of penile cancer for use in clinical practice. Organ-preserving surgery should be offered for treatment of the primary tumour when feasible. Adequate and timely LN management remains a challenge, especially in advanced disease stages. Referral to centres of expertise is recommended. PATIENT SUMMARY Penile cancer is a rare disease that significantly impacts quality of life. While the disease can be cured in most cases without lymph node involvement, management of advanced disease remains challenging. Many unmet needs and unanswered questions remain, underlining the importance of research collaborations and centralisation of penile cancer services.

Abstract
Background Few reports have investigated the oncologically safe timing of prophylactic inguinal lymphadenectomy for penile cancer patients with clinically normal inguinal lymph nodes (cN0), particularly those who received delayed surgical treatment. Methods The study included pT1aG2, pT1b-3G1-3 cN0M0 patients with penile cancer who received prophylactic bilateral inguinal lymph nodes dissection (ILND) at the Department of Urology of Tangdu Hospital between October 2002 and August 2019. Patients who received simultaneous resection of primary tumor and inguinal lymph nodes were assigned to the immediate group, while the rest were assigned to the delayed group. The optimal timing of lymphadenectomy was determined based on the time-dependent ROC curves. The disease-specific survival (DSS) was estimated based on the Kaplan-Meier curve. Cox regression analysis was used to evaluate the associations between DSS and the timing of lymphadenectomy and tumor characteristics. The analyses were repeated after stabilized inverse probability of treatment weighting adjustment. Results A total of 87 patients were enrolled in the study, 35 of them in the immediate group and 52 in the delayed group. The median (range) interval time between primary tumor resection and ILND of the delayed group was 85 (29-225) days. Multivariable Cox analysis demonstrated that immediate lymphadenectomy was associated with a significant survival benefit (HR, 0.11; 95% CI, 0.02-0.57; p = 0.009). An index of 3.5 months was determined as the optimal cut-point for dichotomization in the delayed group. In high-risk patients who received delayed surgical treatment, prophylactic inguinal lymphadenectomy within 3.5 months was associated with a significantly better DSS compared to dissection after 3.5months (77.8% and 0%, respectively; log-rank p<0.001). Conclusions Immediate and prophylactic inguinal lymphadenectomy in high-risk cN0 patients (pT1bG3 and all higher stage tumours) with penile cancer improves survival. For those patients at high risk who received delayed surgical treatment for any reason, within 3.5 months after resection of the primary tumor seems to be an oncologically safe window for prophylactic inguinal lymphadenectomy.

Abstract
Objective To assess the safety and efficacy of the application of self-made non-inflating suspension technique in video endoscopic inguinal lymph node dissection (ILND). Methods We collected 8 patients with penile carcinoma who underwent noninflating video-endoscopic ILND in the Department of Urology, the First Affiliated Hospital of Anhui Medical University, from May 2019 to March 2021. Then, surgical duration, blood loss, drainage tube indwelling time, hospital stay, number of dissected lymph nodes, and complications in the patients were analyzed. Results All patients (n = 8) finished the surgery successfully, with an average surgical duration of 125 (105-145) minutes, blood loss of 41 (25-50) mL, indwelling time of drainage tube of 7 (5-12) days, and a hospital stay of 14.8 (9-21) days. Additionally, 8.8 (3-14) left side and 7.3 (2-17) right side lymph nodes were dissected on average. Complications occurred in 3 patients during a perioperative period. The patients were followed up for 6-24 months, and none suffered recurrence or metastasis. Conclusion The efficacy of noninflating video-endoscopic ILND is good. Patients who have undergone the surgery not only have few postoperative complications but also have a good prognosis, suggesting the safety and availability of the clinical application.

Abstract
Purpose The aim of this study is to investigate the trends in incidence and mortality, and explore any change in survival of penile cancer in the United States. Methods We obtained data from the Surveillance, Epidemiology, and End Results (SEER) database (2000-2018) utilizing the SEER Stat software. The joinpoint regression was used to analyze the secular trend of incidence and incidence-based mortality (IBM) stratified by age, race, and summary stage. The 5-year relative survival rate was also calculated. Result The age-adjusted rates of penile cancer patients were 0.38 (0.37-0.39) and 0.21 (0.2-0.21) for overall incidence and IBM, respectively. The 5-year relative survival rates were 67.7%, 66.99%, and 65.67% for the calendar periods of 2000-2004, 2005-2009, and 2010-2014, respectively. No significant changes in incidence by era were observed from 2000 to 2018 [annual percentage change (APC) = 0.5%, p = 0.064]. The IBM rate of penile cancer showed an initial significant increase from 2000 to 2002 (APC = 78.6%, 95% CI, -1.7-224.6) followed by a deceleration rate of 4.6% (95% CI, 3.9-5.3) during 2002 to 2018. No significant improvement in 5-year relative survival was observed. The trends by age, race, and summary stage in incidence and IBM were significantly different. Conclusion This study, using population-level data from the SEER database, showed an increasing trend in IBM and no significant improvement in the 5-year relative survival rate. Meanwhile, the incidence of penile cancer exhibited a relatively stable trend during the study period. These results might be due to the lack of significant progress in the treatment and management of penile cancer patients in the United States in recent decades. More efforts, like increasing awareness among the general population and doctors, and centralized management, might be needed in the future to improve the survival of this rare disease.

[PMID: 35718135 DOI: 10.1016/j.urology.2022.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 05/30/2022] [Accepted: 06/05/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVES To describe our modified technique of performing video endoscopic inguinal lymphadenectomy (VEIL) with the proposed benefits of a shallow learning curve and better ergonomics. METHODS We describe our modified VEIL technique: the deep first approach, in a squamous cell carcinoma penis patient with a pathological T3 disease and bilateral palpable, mobile inguinal lymph nodes post penectomy. RESULTS The surface markings and the port incision sites for the procedure were conventional. However, in contrast to the standard superficial dissection plane development below the Scarpa's fascia at the initial camera port site, our technique commenced with a deep dissection plane just above the fascia lata. The dissection limits were directly identified: the sartorius muscle laterally, the inguinal ligament superiorly, and the adductor longus muscle medially. The saphenous vein was identified early and close to the saphenofemoral junction, allowing undemanding dissection. The superficial flap dissection was done entirely under direct vision, with better ergonomics owing to a continuous counter-traction by the pressure of insufflated gas. Deep inguinal nodal dissection then concluded the procedure. CONCLUSIONS The described technique is surmised to be easier to perform, given the lack of ambiguity in the correct initial dissection plane, direct visualization of surgical landmarks early in the procedure, and early identification of the saphenous vein close to the SFJ. It may improve the learning curve allowing for a wider acceptance of VEIL.

Minimally invasive evaluation of the clinically negative inguinal node in penile cancer: Dynamic sentinel node biopsy. Urol Oncol 2022; 40:209-214. [PMID: 33218920 DOI: 10.1016/j.urolonc.2020.11.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Revised: 09/25/2020] [Accepted: 11/04/2020] [Indexed: 11/21/2022]
Abstract
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.

Front Oncol 2022; 12:850905. [PMID: 35494039 PMCID: PMC9046689 DOI: 10.3389/fonc.2022.850905] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Accepted: 03/14/2022] [Indexed: 11/13/2022] Open
Abstract
Lymph node (LN) management is critical for survival in patients with penile cancer. However, radical inguinal lymphadenectomy carries a high risk of postoperative complications such as lymphedema, lymphocele, wound infection, and skin necrosis. The European Association of Urology guidelines therefore recommend invasive LN staging by modified inguinal lymphadenectomy or dynamic sentinel node biopsy (DSNB) in clinically node-negative patients (cN0) with intermediate- and high-risk tumors (≥ T1G2). However, the timing of DSNB (simultaneous vs. subsequent to partial or total penile resection) is controversial and the low incidence of penile cancer means that data on the long-term outcomes of DSNB are limited. The present study aimed to analyze the reliability and morbidity of DSNB in patients with penile cancer during long-term follow-up. This retrospective study included 41 patients (76 groins) who underwent radioisotope-guided DSNB simultaneously or secondarily after penile surgery from June 2004 to November 2018. In total, 193 sentinel LNs (SLNs) and 39 non-SLNs were removed. The median number of dissected LNs was 2.5 (interquartile range 2-4). Histopathological analysis showed that five of the 76 groins (6.6%) contained metastases. None of the non-SLNs were tumor-positive. In accordance with the guidelines, all inguinal regions with positive SLNs underwent secondary radical inguinal lymphadenectomy, which revealed three additional metastases in one groin. Regional LN recurrence was detected in three patients (four groins) during a median follow-up of 70 months, including two patients in whom DSNB had been performed secondarily after repetitive penile tumor resections. DSNB-related complications occurred in 15.8% of groins. Most complications were mild (Clavien-Dindo grade I; 50%) or moderate (II; 25%), and invasive intervention was only required in 3.9% of groins (IIIa: n = 1; IIIb: n = 2). In summary, this study suggests that the current radioisotope-guided DSNB procedure may reduce the complication rate of inguinal lymphadenectomy in patients with cN0 penile cancer. However, DSNB and penile surgery should be performed simultaneously to minimize the false-negative rate. Recent advances, such as new tracers and imaging techniques, may help to reduce the false-negative rate of DSNB further.

Abstract
PURPOSE To analyse the risk of inguinal lymph node (ILN) metastases in T1G2 penile cancer stratified by lymphovascular invasion (LVI), perineural invasion (PNI) and tumour size. METHODS Retrospective study of men with localised T1G2 penile cancer with non-palpable lymph nodes and no local recurrence during follow-up at six European institutional high-volume centres was performed. ILN involvement was defined as cancer detected during ultrasound-guided fine-needle aspiration cytology, core needle biopsy, dynamic sentinel lymph node biopsy, ILN dissection or inguinal recurrence during follow-up. Uni- and multivariable logistic regression analyses were performed. RESULTS In the cohort of 554 men with T1G2 penile cancer, from 6 European institutions, ILN metastases were observed in 46/554 men (8%, 95% confidence interval (CI) 6-11%). Men with both, LVI- and PNI- primary cancers had the lowest risk of ILN involvement (6%) whereas men with LVI + or PNI + showed ILN metastases in 22% and 30%. In multivariable regression, men with LVI + or PNI + had higher odds for ILN metastases compared to men with LVI- and PNI- (OR 3.9, 95% CI 1.6-9.0, p value < 0.01) Tumour size was not associated with ILN risk (OR 1.01 95% CI 0.99-1.04, p = 0.17). CONCLUSION Approximately, one out of ten men with T1G2 overall and one out of four men with either LVI + or PNI + still have ILN metastases despite being clinically node negative. Therefore, invasive ILN staging should strongly be recommended in T1G2 with LVI + or PNI + but importantly, must be discussed in patients with T1G2 with LVI- or PNI-.

Abstract
INTRODUCTION Lower extremity lymphedema is a major source of morbidity in up to 70% of penile cancer patients. Lymphedema is often thought to be incurable, though surgical treatments have started to emerge. This study is the first to apply lymphovenous bypass specifically to penile cancer patients status post lymphadenectomy. METHODS We performed microsurgical lymphovenous bypass in 3 patients who underwent inguinal lymphadenectomy for advanced penile cancer, and later lymph node transplant in 1 patient. RESULTS The lymphovenous bypass was performed by a trained microsurgeon: Two patients were treated as outpatients for lymphedema, and 1 patient underwent prophylactic lymphovenous bypass simultaneously with initial lymphadenectomy. We saw significant improvement in patient's clinical lymphedema as well as lymphatic drainage on infared imaging for 2 of 3 patients at 12 months, however 1 of these patients did require later lymph node transfer at 24 months. CONCLUSION This early proof of concept study shows that these procedures should be considered and studied further in the treatment and prevention of debilitating lymphedema in the penile cancer population.

Abstract
OBJECTIVE To perform a systematic review and meta-analysis evaluating the peri-operative outcomes, complications, and oncological outcomes of Robotic-Assisted Video-Endoscopic Inguinal Lymphadenectomy (RAVEIL)/Video-Endoscopic Inguinal Lymphadenectomy (VEIL) with Open Inguinal Lymph-Node Dissection (OILND) for management of inguinal lymph-nodes in carcinoma of the penis. METHODS A comprehensive literature search was performed in January 2021 using the PubMed, Embase, and Cochrane databases. Data from human studies comparing RAVEIL/VEIL vs. OILND in carcinoma of penis published in English was extracted and analyzed by two independent authors. RESULTS Two Randomised Controlled Trials and 6 cohort studies were included in the meta-analysis. RAVEIL/VEIL group exhibited increased operative time (Mean Difference [MD] = 15.28 [14.19; 16.38], P < 0.001), shorter hospital stay (MD = -1.06 [-1.14; -0.98], P < 0.001), and decreased duration of drainage (MD = -2.82 [-3.21; -2.43], P < 0.001), wound infection (Odds Ratio [OR] = 0.15 [0.08; 0.27], P < 0.001), skin necrosis (OR = 0.12 [0.05; 0.28], P < 0.001), lymphedema (OR = 0.41 [0.24; 0.72], P = 0.002), and major complications (OR = 0.11 [0.05; 0.24], P < 0.001) as compared to OILND group. Recurrence rate and number of deaths were comparable in both the groups. RAVEIL/VEIL groups showed slightly larger lymph-node yield (MD = 0.44 [0.18; 0.70], P < 0.001) as compared to OILND group. CONCLUSION RAVEIL/VEIL has lesser skin complications, lymphedema, and better lymph-node yield as compared to OILND. It is comparable in terms of lymphocele and recurrence. It has lesser hospital stay and duration of drainage but owing to heterogeneity, the results should be interpreted with caution. Further studies are required to determine long-term oncological outcomes like overall survival and disease-specific survival.

Abstract
PURPOSE Reviewing surgical procedures using fasciocutaneous and myocutaneous flaps for inguinal reconstruction after lymphadenectomy in metastatic penile cancer. MATERIAL AND METHODS We reviewed the current literature of the Pubmed database according to PRISMA guidelines. The search terms used were "advanced penile cancer", "groin reconstruction", and "inguinal reconstruction", both alone and in combination. The bibliographic references used in the selected articles were also analyzed to include recent articles into our research. RESULTS A total of 54 studies were included in this review. About one third of penile cancers are diagnosed with locally advanced disease, often presenting with large lymph node involvement. Defects in the inguinal region resulting from the treatment of metastatic penile cancer are challenging for the surgeon and cause high patient morbidity, rendering primary closure unfeasible. Several fasciocutaneous and myocutaneous flaps of the abdomen and thigh can be used for the reconstruction of the inguinal region, transferring tissue to the affected area, and enabling tensionless closure. CONCLUSIONS The reconstruction of defects in the inguinal region with the aid of flaps allows for faster postoperative recovery and reduces the risk of complications. Thus, the patient will be able to undergo potential necessary adjuvant treatments sooner.

Abstract
Background: Twenty-two cases of penile carcinoma that were managed at our institution over a 5-year period were analysed on the basis of inguinal lymph node dissection (ILND), complications and follow-up. Methods: A total of 22 cases post penectomy were stratified into low risk (T1 G1 or G2 without lympho-vascular invasion and negative on fine-needle aspiration cytology (FNAC)) and high risk (T1 G3 and above and/or lympho-vascular invasion). Low-risk patients having palpable lymphadenopathy were given a course of antibiotics. If the lymph nodes were still palpable, FNAC was done, and patients then underwent superficial ILND (SILND) or even ILND in cases with positive frozen-section reports. In the high-risk group, all patients underwent SILND, and if required, underwent ILND. Two patients in the high-risk group were lost to follow-up after 9 months. Histopathology reports were noted, and patients were followed up for 2 years. Results: In the low-risk group, seven patients had palpable lymph nodes and underwent SILND. The remaining five patients were put on surveillance. Amongst the seven who underwent SILND, six were positive at frozen section, requiring ILND. Nine patients in the high-risk group underwent ILND. Four patients in the ILND group had a minor wound infection. Lymphoedema was seen in two patients which was managed conservatively, and lymphorrhoea was seen in one patient. Flap necrosis occurred in one patient. Recurrences were seen in three patients in the high-risk group. Two who had deep node involvement and who had early nodal recurrence underwent bilateral ILND. One patient in the high-risk group had late ipsilateral nodal recurrence and underwent ipsilateral ILND. There were no regional recurrences. Conclusion: Carcinoma of the penis has high morbidity because of delayed presentation, lack of awareness and poor compliance. This necessitates staging SILND in all high-risk cases for therapeutic and prognostic purposes.

Abstract
Inguinal lymphadenectomy (ILND) remains the standard of care for patients with invasive squamous cell carcinoma of the penis, dictating patient prognosis, adjuvant therapies, and surveillance strategies. Importantly the performance of an ILND has been shown to improve cancer-specific outcomes, providing a modifiable factor for patients with an aggressive malignancy. Surprisingly, the procedure remains underutilized, mainly due to the high surgical morbidity associated with the procedure. The open lymphadenectomy technique has undergone several modifications over the last 30 years to minimize its associated surgical morbidity, but wound-related complications remain significant. Minimally invasive surgery (MIS) techniques have been recently introduced to help mitigate wound-related complications associated with open lymphadenectomy, with promising results. In this review, we highlight the importance of ILND, present a detail review of the surgical and oncological outcomes associated with open, laparoscopic and robotic ILND for patients with penile cancer.

Zhang W, Gao P, Gao J, Wu X, Liu G, Zhang X. A Clinical Nomogram for Predicting Lymph Node Metastasis in Penile Cancer: A SEER-Based Study. Front Oncol 2021; 11:640036. [PMID: 33768001 PMCID: PMC7985344 DOI: 10.3389/fonc.2021.640036] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Accepted: 02/05/2021] [Indexed: 01/21/2023] Open
Abstract
Purpose: We developed a nomogram to predict the possibility of lymph node metastasis in patients with squamous cell carcinoma of the penis. Methods: Identifying patients with squamous cell carcinoma of the penis diagnosed between 2004 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate analyses were carried out by logistic regression to assess significant predictors associated with lymph node metastasis. A nomogram was established and validated by a calibration plot and receptor operating characteristic curve (ROC) analysis. Results: A total of 1,016 patients with penile squamous cell carcinoma (SCCP) were enrolled in this study. One hundred and ninety-five patients (19%) had lymph node involvement (N1-3). Multivariate analysis showed that age, primary tumor site, grade, tumor size, and T stage were identified as being significantly (p < 0.05) associated with lymph node involvement. All the above factors that showed a statistically significant predictive capability were selected for building the nomogram. This model had a calibration slope of 0.9 and a c-index of 0.776, indicating the good discrimination and effectiveness of the nomogram in predicting lymph node status. Conclusion: Although the prediction model has some limitations, the nomogram revealed the relationship between the clinicopathological characteristics of SCCP patients and the risk of lymph node metastasis. This tool will assist patients in counseling and guide treatment decisions for SCCP patients.

Abstract
Penile squamous cell carcinoma (PSCC) is a rare cancer with orphan disease designation and a prevalence of 0.1-1 per 100,000 men in high-income countries, but it constitutes up to 10% of malignancies in men in some African, Asian and South American regions. Risk factors for PSCC include the absence of childhood circumcision, phimosis, chronic inflammation, poor penile hygiene, smoking, immunosuppression and infection with human papillomavirus (HPV). Several different subtypes of HPV-related and non-HPV-related penile cancers have been described, which also have different prognostic profiles. Localized disease can be effectively managed by topical therapy, surgery or radiotherapy. As PSCC is characterized by early lymphatic spread and imaging is inadequate for the detection of micrometastatic disease, correct and upfront surgical staging of the inguinal lymph nodes is crucial in disease management. Advanced stages of disease require multimodal management. Optimal sequencing of treatments and patient selection are still being investigated. Cisplatin-based chemotherapy regimens are the mainstay of systemic therapy for advanced PSCC, but they have poor and non-durable responses and high rates of toxic effects, indicating a need for the development of more effective and less toxic therapeutic options. Localized and advanced penile cancers and their treatment have profound physical and psychosexual effects on the quality of life of patients and survivors by altering sexual and urinary function and causing lymphoedema.

Abstract
Cancer of the penis is an important health problem in India, causing significant morbidity. Involvement of locoregional lymph nodes is the most significant prognostic factor for patients with penile cancer. In this study, we reviewed clinical data of all patients who underwent modified inguinal lymph node dissection as a means to diagnose micro-metastasis in inguinal lymph nodes, and analysed the outcomes. We retrospectively reviewed the hospital clinical charts of patients treated for carcinoma of the penis. Inguinal and distant metastases were assessed by physical examination, ultrasound imaging of the inguinal region, computed tomography of the abdomen and pelvis and a chest radiograph. Patients with clinically negative inguinal lymph nodes underwent modified lymph node dissection (mILND) both to diagnose and stage the disease. Complications occurring during a 30-day period after surgery were defined as early and thereafter as late complications. A total of 40 patients with a mean age of 52.27±13.10 (range 25-73) years underwent mILND. Wedge biopsy from the primary lesion had revealed intermediate-risk disease in 22 (55%) patients and high-risk disease in 18 (45%) patients. Histopathological examination of the primary penile lesion revealed a pT1 lesion in 32 patients and a pT2 lesion in the remaining 8 patients. Fourteen (35%) of the 40 patients showed micro-metastases in the inguinal lymph nodes on frozen sections. The mean follow-up in these patients was 56.6±18.09 months. There were no instances of local or systemic recurrences seen in 38 (95%) patients within 5 years. Superficial lymph node dissection and where facilities are available DSLNB remain the standard of care in the management of patients with clinically groin-negative (cN0) intermediate- and high-risk groups. Modified inguinal lymph node dissection would be a safe and appropriate alternative to this in all centres that do not have access to newer modalities like DSLNB, video-endoscopic (VEIL) or robotic-assisted techniques.

Abstract
BACKGROUND Penile cancer is a rare malignancy and the wide range of quality of care associated with it often results in inferior oncologic and functional treatment outcomes. OBJECTIVES Assessment of the current healthcare situation in clinical routine and identification of the relevant key features and reference values for quality of care. MATERIALS AND METHODS Search for relevant peer-reviewed articles and published congress abstracts in Medline, Embase and other databases as well as Google web search engine. RESULTS Key quality features of penile cancer management include organ-sparing surgery of the primary tumor, invasive inguinal lymph node staging and systemic treatment. Adherence to treatment guidelines is currently low. Centralization of care has already led to a considerable improvement in the quality of care in some areas and increasing conformity with the guidelines' recommendations. CONCLUSION Centralization of care and networks based on this can significantly improve patient outcomes. Thus, reference values for core parameters of quality cancer care can be generated and validated. Moreover, organ-sparing surgery, invasive lymph node staging and systemic therapy should be increasingly utilized. As a reference value, 90% adherence to the guidelines for these three features is recommended. However, before centralization of care can be introduced, aspects relevant to practical implementation must be addressed, such as the reimbursement of travel costs for those affected, infrastructure costs and instruments to measure quality of life and patient satisfaction after centralization.

Practice Patterns Among Penile Cancer Surgeons Performing Dynamic Sentinel Lymph Node Biopsy and Radical Inguinal Lymph Node Dissection in Men with Penile Cancer: A eUROGEN Survey. EUR UROL SUPPL 2021; 24:39-42.

Abstract
Dynamic sentinel lymph node biopsy (DSNB) and radical inguinal lymph node dissection (ILND) are important in the management of penile cancer patients, but high-level evidence for preoperative, perioperative, and postoperative management remains scarce. According to an online survey of 35 surgeons from ten European countries, 57% perform >10 ILND procedures per year and 86% offer DSNB. Furthermore, management differs substantially for dye injection site, use of lymphoscintigraphy, preferred incision sites, techniques for lymphatic control, duration of empiric antibiotic therapy, perioperative thromboprophylaxis, time points for drain removal, and definition of the ILND dissection floor. Consensus was observed for the use of perioperative antibiotics (although not duration and type) and the borders for ILND template definitions. We conclude that there is significant variation in patient management among eUROGEN penile cancer surgeons. This heterogeneity may confound multicentre studies; therefore, a consensus to standardise inguinal node management in penile cancer across European penile cancer centres is warranted. Patient summary Our survey reveals that preferences and surgical techniques for inguinal lymph node sampling and removal varies significantly between European penile cancer surgeons. Consensus is needed to standardise the management approach for penile cancer.

Abstract
PURPOSE Penile cancer is highly prevalent in low- and middle-income countries, with significant morbidity and mortality rates. The first Brazilian consensus provides support to improve penile cancer patients' outcomes, based on expert's opinion and evidence from medical literature. METHODS Fifty-one Brazilian experts (clinical oncologists, radiation oncologists, urologists, and pathologists) assembled and voted 104 multiple-choice questions, confronted the results with the literature, and ranked the levels of evidence. RESULTS Healthcare professionals need to deliver more effective communication about the risk factors for penile cancer. Staging and follow-up of patients include physical examination, computed tomography, and magnetic resonance imaging. Close monitoring is crucial, because most recurrences occur in the first 2-5 years. Lymph-node involvement is the most important predictive factor for survival, and management depends on the location (inguinal or pelvic) and the number of lymph nodes involved. Conservative treatment may be helpful in selected patients without compromising oncological outcomes; however, surgery yields the lowest rate of local recurrence. CONCLUSION This consensus provides an essential decision-making orientation regarding this challenging disease.

Abstract
Penile cancer is an uncommon disease associated with significant psychological and physical morbidity. Penile cancer has an expectable pattern of spread in a stepwise fashion, from inguinal to pelvic lymph nodes (PLN) then distant spread. Patients with penile cancer have variable survival, with patients with a low burden of nodal metastatic disease having lasting survival with surgical management, however patients with a large amount of locoregional metastatic disease having a worse prognosis. The current management options for patients with metastatic lymph node disease in penile cancer aims to reduce the morbidity associated with radical inguinal lymph node (ILN) surgery with appropriate risk stratification to optimise oncological control of the disease. This article describes current challenges in managing the inguinal region in patients with penile squamous cell carcinoma (SCC).

Abstract
Penile cancer (PeCa) is a rare disease worldwide, accounting for less than one percent of all malignancies in men. It usually presents as a painless ulcer or lump on the head of the penis. Squamous cell carcinoma represents the most common histological subtype of PeCa, with pathogenesis intimately linked to chronic Human Papilloma Virus (HPV) infection. Surgery is the cornerstone for the treatment of primary PeCa with potential mutilating outcome depending on the nodal extension of the disease. However, in case of extensive lymph node involvement, multidisciplinary treatment including perioperative chemotherapy and inclusion in clinical trial should be considered. To date, advanced or metastatic disease still have poor prognosis and are a therapeutic challenge with limited options, highlighting the need of new treatments and further investigations. Growing efforts to identify molecular alterations, understand the role of HPV and characterize immune contexture have expanded over the past years, providing further perspectives in prognostication, predictive biomarkers and therapeutic intervention. In this review, we provide an updated overview of current management of PeCa focusing on perioperative strategy. We discuss about new insights of the biology of PeCa and comment future directions in the field.

Abstract
Our aim is to review the benefits as well as techniques, surgical outcomes, and complications of minimally invasive inguinal lymph node dissection (ILND) for penile cancer. The PubMed, Wiley Online Library, and Science Direct databases were reviewed in March 2020 for relevant studies limited to those published in English and within 2000–2020. Thirty-one articles describing minimally invasive ILND were identified for review. ILND has an important role in both staging and treatment of penile cancer. Minimally invasive technologies have been utilized to perform ILND in penile cancer patients with non-palpable inguinal lymph nodes and intermediate to high-risk primary tumors or patients with unilateral palpable non-fixed inguinal lymph nodes measuring less than 4 cm, including videoscopic endoscopic inguinal lymphadenectomy (VEIL) and robotic videoscopic endoscopic inguinal lymphadenectomy (RVEIL). Current data suggest that VEIL and RVEIL are feasible and safe with minimal intra-operative complications. Perhaps the strongest appeal for the use of minimally-invasive approaches is their faster post-operative recovery and less post-operative complications. As a result, patients can tolerate this procedure better and surgeons can offer surgery to patients who otherwise would not be a candidate or personally willing to undergo surgery. When compared to open technique, VEIL and RVEIL have similar dissected nodal count, a surrogate metric for oncological adequacy, and a none-inferior inguinal recurrence rate. Larger randomized studies are encouraged to investigate long-term outcome and survival rates using these minimally-invasive techniques for ILND.

Abstract
Objective: The role of pelvic lymph node dissection (PLND) is still debated in patients with N3 stage penile cancer. In Denmark this subgroup of patients is in general managed with an inguinal lymphadenectomy (ILND) and adjuvant chemoradiation and PLND is not offered as a standard. The objective of this study was to report treatment outcomes of this regimen and compare this with existing literature.Materials and methods: We retrospectively reviewed records of patients with pT1-T4, N3, M0 penile cancer diagnosed between 1st January 2010 and 31th December 2014 in Denmark and treated with curative intend.Results: 21 patients were identified with a median follow up of 74 months (CI 54-94). Management of the penile lesion was local resection in 5 (23.8%), partial penectomy in 10 (47.6%), and total penectomy in 6 (28.6%) of patients. Regarding the most extensive lymph node (LN) surgery: 4 patients (23,8%) went directly to oncological treatment from sentinel node biopsy with no further LN dissection, 6 patients (28.6%) were treated with unilateral ILND, 10 patients (47.6%) with bilateral ILND and a single patient (4.8%) was treated with ILND and PLND. In the adjuvant setting patients were treated with external beam therapy of involved regions and cisplatin-based chemotherapy. Median overall survival was 84 months (CI 0-176). The 5-year probability of surviving penile cancer was 57.1% (CI 36.0-78.3).Conclusion: Treatment with surgery and chemo-irradiation in this national cohort does not show inferior survival outcomes compared to historical cohorts.
