RESUMO
BACKGROUND: This study aimed to investigate the safety and feasibility of indocyanine green near-infrared fluorescence (ICG-NIR) fluorescence-guided video-endoscopic inguinal lymphadenectomy (VEIL) for rectal cancer with inguinal lymph node metastasis (ILNM). METHODS: A retrospective analysis was conducted on 11 patients with rectal cancer who underwent ICG-NIR fluorescence-guided VEIL, assessing various parameters such as operation time, intraoperative bleeding, number of harvested lymph nodes, intraoperative and postoperative complications, and follow-up. RESULTS: Regarding surgical procedures for ILNM, unilateral surgery was performed in 7 cases (54.5%) and bilateral surgery in 4 cases (45.5%). Among these 15 ICG-NIR-guided VEIL surgeries in 11 patients, positive fluorescence visualization was achieved in 13 operations (86.7%). The median estimated blood loss was 10 ml, and the median operation time was 90 min. One case (6.7%) required conversion to open surgery. The median duration of the drain tube was 12 days, and the median length of postoperative hospital stay was 20 days. Postoperative complications were observed, including incisional infection in 2 cases (18.2%), lymphatic leakage in 5 cases (45.5%), urinary infection in 1 case (9.1%), and pneumonia in 3 cases (27.3%). Complications such as skin necrosis, lower limb venous thrombosis, lower limb swelling, or impaired movement were observed during the postoperative follow-up period. No cases of primary lesion, groin, or pelvic lymph node recurrence were observed. CONCLUSION: ICG-NIR fluorescence-guided VEIL is a safe and feasible surgical treatment for rectal cancer with ILNM. ICG fluorescence guidance holds promise as a more personalized and precise approach for VEIL in rectal cancer surgery.

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.

Primary penile extraosseous osteosarcoma (EOS) ranks the most uncommon amongst the differential penile masses, with only nine cases reported so far. In this report, we share the management of a 67-year-old Hispanic male who presented with a painful mass over his distal penile shaft and glans for the last two months. After initial imaging and complete blood investigations, he underwent partial penectomy. Histology revealed high-grade sarcoma, with osteoid production, favoring high-grade extra-skeletal osteosarcoma, with tumor necrosis involving approximately 5% of the tumor volume. The patient had bilateral palpable inguinal lymphadenopathy, which was seen even on a pre-op CT scan. The patient thus underwent bilateral robotic superficial and deep inguinal standard template lymph node dissection three weeks after his partial penectomy. His pathology was negative for malignancy in all examined lymph nodes. At his last follow-up, five months post his primary surgery, he had been doing well without concerns for recurrence.
RESUMO
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.

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.

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.

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.

INTRODUCTION: Inguinal lymph node dissection (ILND) plays an important role for both staging and treatment purposes in patients diagnosed with penile carcinoma (PeCa). Video-endoscopic inguinal lymphadenectomy (VEIL) has been introduced to reduce complications, and in those patients elected for bilateral ILND, a simultaneous bilateral VEIL (sB-VEIL) has also been proposed. This study aimed to investigate the feasibility, safety, and preliminary oncological outcomes of sB-VEIL compared to consecutive bilateral VEIL (cB-VEIL). MATERIAL AND METHODS: Clinical N0-2 patients diagnosed with PeCa and treated with cB-VEIL and sB-VEIL between 2015 and 2023 at our institution were included. Modified ILND was performed in cN0 patients, while cN+ patients underwent a radical approach. Intra- and postoperative complications, operative time, time of drainage maintenance, length of hospital stay and readmission within 90 days, as well as lymph node yield, were compared between the two groups. RESULTS: Overall, 30 patients were submitted to B-VEIL. Of these, 20 and 10 patients underwent cB-VEIL and sB-VEIL, respectively. Overall, 16 (80%) and 7 (70%) patients were submitted to radical ILND due to cN1-2 disease in the cB-VEIL and sB-VEIL groups, respectively. No statistically significant difference emerged in terms of median nodal yield (13.5 vs. 14, p = 0.7) and median positive LNs (p = 0.9). sD-VEIL was associated with a shorter operative time (170 vs. 240 min, p < 0.01). No statistically significant difference emerged in terms of intraoperative estimated blood loss, length of hospital stay, time to drainage tube removal, major complications, and hospital readmission in the cB-VEIL and sB-VEIL groups, respectively (all p > 0.05). CONCLUSIONS: Simultaneous bilateral VEIL is a feasible and safe technique in patients with PeCA, showing similar oncological results and shorter operative time compared to a consecutive bilateral approach. Patients with higher preoperative comorbidity burden or anesthesiological risk are those who may benefit the most from this technique.
RESUMO
PURPOSE: Modified and superficial inguinal lymph node dissection (MILD and SILD) are the 2 widely used templates for surgical staging of clinically node negative (cN0) penile cancer (PeCa); however, no previous reports have compared their outcomes. We compared these 2 surgical templates for oncological outcomes and complications. MATERIALS AND METHODS: We retrospectively reviewed records of cN0 PeCa patients who underwent MILD/SILD at our cancer care center from January 2013 to December 2019. Patients who developed a penile recurrence during follow up were excluded from analysis of oncological outcomes. The 2 groups (MILD and SILD) were compared for baseline clinico-pathological characteristics. The primary outcome was the groin recurrence free survival (gRFS). Secondary outcomes included the false negative rate (FNR) and disease free survival (DFS) for both templates and also the post-operative wound related complication. RESULTS: Of the 146 patients with intermediate and high risk N0 PeCa, 74 (50.7%) and 72 (49.3%) underwent MILD and SILD respectively. The 2 groups were comparable with regards to the distribution of T stage, tumor grade and the proportion of intermediate and high-risk patients. At a median follow up of 34 months (47 for SILD and 23 for MILD), a total of 5 groin recurrences were encountered; all of them occurred in the MILD group. The gRFS and DFS for the MILD group was 93.2% and 91.8% respectively; while that for the SILD group was 100% and 94.4% respectively. Too few events had occurred to determine any statistically significant difference. The FNR for MILD and SILD was 26.3% and 0% respectively. The overall complication rate was significantly higher in the SILD group (46% vs 20.3%, p=0.001), especially for Clavien Dindo 3A complications. CONCLUSION: MILD can fail to pick up micro-metastatic disease in a small proportion of cN0 PeCa patients, while SILD provides better oncological clearance with no groin recurrences. This oncological superiority comes at the cost of a higher incidence of wound-related complications.

Penile cancer is a rare malignancy, most commonly diagnosed in older men, associated with poor outcomes, dramatic decline in quality of life and sexual function. Squamous cell carcinoma is the most common histopathology of penile cancer, accounting for 95% of all cases. Localized, early-stage penile cancer can be effectively managed through penile-sparing techniques in many cases, though advanced stages of penile cancer carry a poor prognosis. Current innovative treatments are exploring the role of targeted therapy, HPV-directed therapy, immune checkpoint inhibitors and adoptive T-cell therapies in treatment and prevention of relapse of penile cancer. Clinical trials are investigating the potential of targeted therapies and immune checkpoint inhibitors in advanced penile cancer. This review examines the current management of penile cancer and highlights future directions in research and treatment.
RESUMO
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.

INTRODUCTION: To evaluate the role of unilateral inguinal lymph-node dissection (ILND) plus contralateral dynamic sentinel node biopsy (DSNB) vs. bilateral ILND in clinical N1 (cN1) penile squamous cell carcinoma (peSCC) patients. MATERIAL AND METHODS: Within our institutional database (1980-2020, included), we identified 61 consecutive cT1-4 cN1 cM0 patients with histological confirmed peSCC who underwent either unilateral ILND plus DSNB (26) or bilateral ILND (35). RESULTS: Median age was 54 years (Interquartile range [IQR]: 48-60 years). Median follow-up was 68 months (IQR 21-105 months). Most patients had pT1 (23 %) or pT2 (54.1%), as well as G2 (47.5%) or G3 (23%) tumors, while lymphovascular invasion (LVI) was present in 67.1% of cases. Considering a cN1 and a cN0 groin, overall 57 out of 61 patients (93.5%) had nodal disease in the cN1 groin. Conversely, only 14 out of 61 patients (22.9%) had nodal disease in the cN0 groin. 5-year IR-free survival was 91% (Confidence interval [CI] 80%-100%) for bilateral ILND group and 88% (CI 73%-100%) for the ipsilateral ILND plus DSNB group (P-value 0.8). Conversely, 5-year CSS was 76% (CI 62%-92%) for bilateral ILND group and 78% (CI 63%-97%) for the ipsilateral ILND plus contralateral DSNB group (P-value 0.9). CONCLUSIONS: In patients with cN1 peSCC the risk of occult contralateral nodal disease is comparable to cN0 high risk peSCC and the gold standard, namely bilateral ILND, may be replaced by unilateral ILND and contralateral DSNB without affecting positive node detection, IRRs and CSS.

PURPOSE: This study was done to find out the clinicopathological characteristics of carcinoma penis in Nepali population and to evaluate various risk factors that predict its inguinal lymph node metastasis. METHODS: A retrospective cross-sectional study was carried out at the Urology Unit, Department of Surgical Oncology at BP Koirala Memorial Cancer Hospital, Bharatpur, Nepal. Case notes of biopsy-proven penile cancer, from January 2012 to December 2021, who underwent some form of surgical intervention were included. RESULTS: A total of 380 patients were included in the study. The mean age of the patients was 55.92 ± 13.81 years. At presentation, 78.5% had clinically node-positive disease. The most common treatment for the primary tumor was partial amputation of the penis (74.2%). Bilateral inguinal lymph node dissections were done in 370 cases. The most common histology was the usual SCC in 94.2% of cases and 69% were well differentiated. T3 was the most common staging in 49.4% cases. Pathologically nodal negative status was found in 58% cases. In univariate analysis, factors like duration of symptoms (≥ 6 months), high-risk histopathology (basaloid/sarcomatoid variant), increased T-stage, poorly differentiated tumor, and the presence of PNI or LVI were significantly associated with lymph node metastasis. CONCLUSIONS: Penile cancer is a common cancer in developing countries such as Nepal. The majority of the patients present late. Early recognition and prompt treatment are required to improve the overall outcome.

PURPOSE: To assess the morbidity of inguinal lymph node dissection (ILND) in penile cancer, then to compare this morbidity with that of ILND performed in the context of skin cancer treatment. METHODS: We retrospectively included all patients having undergone ILND between 1 January 2004 and 31 December 2019 in our centre's urology department in the context of treatment of penile cancer or skin cancer. Postoperative complications were reported in accordance with the Clavien-Dindo classification system. RESULTS: Two hundred forty-two ILNDs were performed in 122 patients with penile cancer and 56 ILNDs were performed in 56 patients with skin cancer. The most common early complication was postoperative fluid collection (lymphocele or haematoma), which complicated 44% of ILNDs overall and 60% of radical lymphadenectomies. The most common late complication was leg lymphoedema, found in up to 36% of radical lymphadenectomies. Major complications (grade ≥ III) were very rare (4% of radical lymphadenectomies). Radical lymphadenectomies resulted in significantly more cases of postoperative fluid collection, skin necrosis and dehiscence, as well as leg lymphoedema, than modified lymphadenectomy techniques. Two factors significantly increasing postoperative morbidity were demonstrated: ASA score = 3 (OR = 3.09) and operating time (OR = 1.01). CONCLUSION: ILNDs are morbid surgical procedures for which the indications must be well defined. However, the complications are almost exclusively minor, for a major oncological benefit.

OBJECTIVE: To investigate the safety and efficacy of the two-channel dilatation procedure for subcutaneous tunneling in the lower abdomen during pelvic lymph node dissection for penile cancer. METHODS: A retrospective analysis was conducted on the clinical data of 6 patients treated from January 2020 to December 2022 using the dual-channel expansion technique for penile cancer lymph node dissection. RESULTS: All 6 cases ( 12 sides) successfully underwent prophylactic inguinal lymph node dissection. The average laparoscopic dissection time was ( 82.50 ± 12.08) minutes per side, with an average blood loss of ï¼28.33 ± 10.95ï¼ ml. The number of lymph nodes dissected was ï¼11.16 ± 1.02ï¼ for the superficial group and ( 0.67 ± 0.74 ) for the deep group. Postoperative pathology was negative in all cases. The average postoperative hospital stay was ï¼7.33 ± 1.60 ï¼ days, with a catheter removal time of ï¼12.00 ± 2.06ï¼days. Postoperative complications included abnormal skin sensations in 5 sides, lower limb edema in 3 sides, lymphedema in 3 sides, and cellulitis in 1 side. During a follow-up period of ï¼20.60 ± 12.51ï¼months, there were no instances of tumor recurrence or metastasis in the inguinal region among the patients. CONCLUSION: The dual-channel expansion technique for inguinal lymph node dissection via a subcutaneous tunnel is a safe and feasible treatment for penile cancer. It has a low complication rate, allows for thorough dissection of inguinal lymph nodes, and offers advantages in terms of surgical time.

PURPOSE: Rectal or anal canal adenocarcinoma with inguinal lymph node metastasis (ILNM) is rare and is associated with poor prognostic outcomes. This study aimed to elucidate the clinical significance of neoadjuvant therapy followed by selective inguinal lymph node dissection and total mesorectal excision for rectal or anal canal adenocarcinoma with clinically suspected ILNM. METHODS: This study enrolled 15 consecutive patients who underwent neoadjuvant therapy and curative resection for rectal or anal canal adenocarcinoma with clinically suspected ILNM between 2005 and 2019 at a single institution. Inguinal lymph node dissection was selectively performed on the side of suspected metastasis before neoadjuvant therapy. Short- and long-term outcomes were retrospectively reviewed. RESULTS: Out of the15 patients, 11 were treated with neoadjuvant chemoradiation, three with chemotherapy, and one with chemoradiation followed by chemotherapy. Fluorodeoxyglucose (FDG)-positron emission tomography (PET) scans were performed after neoadjuvant therapy in 14 patients. Five patients had negative FDG accumulation in inguinal lymph nodes on FDG-PET scan, and their inguinal lymph nodes were also pathologically negative for metastasis. Of the nine patients who had positive FDG accumulation, four had pathologically positive inguinal lymph nodes. Seven patients (46.7%) had inguinal seroma postoperatively. Five-year-overall survival was 77.5%, and 5-year-relapse-free survival was 64.2%. No patient had a recurrence in the inguinal region. CONCLUSION: In patients with rectal or anal canal adenocarcinoma associated with clinical ILNM, radical resection with neoadjuvant therapy provides a good long-term survival.

Inguinal lymph node status is the single most important prognostic factor for survival in patients with carcinoma penis. Various modifications and alternatives to open inguinal lymph node dissection have been developed as the same is associated with high postoperative morbidity such as wound infection, skin flap necrosis, lymphorrhea, and lymphedema. Robot-assisted video endoscopic inguinal lymph node dissection (RA-VEIL) has the potential to accomplish thorough inguinal lymph node dissection with definitively reduced postoperative morbidity. In this video, we demonstrate our technique of RA-VEIL: The fascia lata first approach and highlight our technical modifications of the conventionally described procedure.

OBJECTIVE: The objective of this study was to compare the rate of groin recurrence among women undergoing superficial or deep inguinal lymph node dissections in suspected early-stage vulvar carcinoma. Secondary objectives included comparison of overall survival and post-operative morbidity between the study groups. METHODS: A retrospective cohort of 233 patients with squamous cell carcinoma (SCC) of the vulva who underwent an inguinal lymph node dissection at two major academic institutions from 1999 to 2017 were analyzed. Demographic, surgical, recurrence, survival, and post-operative morbidity data were collected for 233 patients, resulting in a total of 400 groin node dissections analyzed. RESULTS: Rates of overall primary recurrence of disease between superficial and deep inguinal LND (42.5 vs. 39.8%, p = 0.70) and rates of inguinal recurrence (3.4 vs. 8.3%, p = 0.16) were similar. Overall rates of postoperative morbidity were significantly higher in the cohort undergoing deep LND (70.3% vs 44.3%, p < 0.01). Rates of lymphedema (42.4 vs 15.9%, p < 0.01), readmission (26.3 vs 6.8%, p < 0.01), and infection (40.7 vs 14.8%, p < 0.01) were all significantly higher among patients undergoing deep LND. There was no significant difference noted in overall survival between the study groups when adjusting for stage and age (HR 1.08, p = 0.84). CONCLUSION: Superficial inguinal LND had no significant difference in rate of recurrence or overall survival when compared to deep inguinal LND in patients with vulvar SCC. Those who received a deep LND had a significant increase in overall morbidity, including lymphedema, readmission, and infection. For patients who cannot undergo or fail sentinel lymph node mapping, a superficial inguinal lymph node dissection may have similar outcomes in recurrence and overall survival with a reduction in overall morbidity as compared to a complete, or deep, lymph node dissection.
