Morbidity of inguinal lymphadenectomy for invasive penile carcinoma

OBJECTIVE: To determine the incidence and the consequences of complications related to modified and radical inguinal lymphadenectomy in patients with invasive penile carcinoma, defined by invasion of the corpus spongiosum or cavernosum (> or =T2). MATERIALS AND METHODS: A total of 118 modified (67.0%), and 58 radical (33.0%) inguinal lymphadenectomy were performed in 88 patients between 1989 and 2000. To decrease the morbidity, radical inguinal lymphadenectomy was proposed only in patients with palpable inguinal lymph nodes, uni- or bilaterally (N1 or N2). Modified inguinal lymphadenectomy was performed bilaterally in patients with invasive penile carcinoma and non-palpable inguinal lymph nodes (N0), and unilaterally in the side without inguinal metastases in N1 patients. Complications were assessed retrospectively with a median follow-up of 46 months and classified as early (event observed during the 30 days after the procedure) or late (event present after hospitalisation or after the first months). RESULTS: A total of 74 complications after 176 procedures were recorded. After modified inguinal lymphadenectomy, 8 early (6.8%) and 4 late (3.4%) complications were observed. There were a total of 110 dissections with no complications and 8 dissections with 1 or 2 complications. After radical inguinal lymphadenectomy, the morbidity increased with 24 early (41.4%) and 25 late (43.1%) complications, observed in only 18 of 58 radical procedures. Leg oedema was the most common late complication, interfering with ambulation in 13 cases (22.4%). CONCLUSION: Modified inguinal lymphadenectomy, with saphenous vein sparing and limited dissection offers excellent functional outcome in patients with invasive penile carcinoma and nonpalpable inguinal lymph nodes. The morbidity after radical lymphadenectomy still significant, especially in patients with multiple or bilateral superficial inguinal lymph nodes treated by pelvic and bilateral inguinal lymphadenectomy.

Video endoscopic inguinal lymphadenectomy: a new minimally invasive procedure for radical management of inguinal nodes in patients with penile squamous cell carcinoma

PURPOSE: Video endoscopic inguinal lymphadenectomy is a recently described lymphadenectomy with the same template of the open technique but performed with laparoscopic instruments under video guidance. It was developed to decrease procedure related morbidity while maintaining good oncological results. We report our initial results in a trial comparing video endoscopic inguinal lymphadenectomy with standard inguinal lymphadenectomy. MATERIALS AND METHODS: From 2003 to 2005, 10 patients with penile carcinoma who were at high risk for inguinal metastases underwent bilateral inguinal lymphadenectomy. We performed standard lymphadenectomy in 1 limb and video endoscopic inguinal lymphadenectomy on the contralateral side. Perioperative results and followup data were compared. RESULTS: No intraoperative complications occurred. Mean operative time was 92 and 126 minutes for open and endoscopic surgery, respectively (p=0.00002). Despite the small number of patients we noted a decrease in cutaneous complications with video endoscopic inguinal lymphadenectomy (0% vs 50%, p=0.017) and a trend toward decreased overall morbidity with this endoscopic technique (20% vs 70%, p=0.059). The mean number of retrieved and positive lymph nodes were similar for the 2 techniques. At a mean followup of 18.7 months (range 12 to 31) no signs of recurrence or disease progression were noted. In the postoperative period 9 of the 10 patients identified video endoscopic inguinal lymphadenectomy as the preferred technique in terms of surgical morbidity. CONCLUSIONS: Video endoscopic inguinal lymphadenectomy is a safe and feasible technique in patients with penile carcinoma and nonpalpable nodes. These preliminary results suggest that video endoscopic inguinal lymphadenectomy may decrease postoperative morbidity without compromising oncological control. Future studies should include the bilateral procedure, longer term followup and a greater number of patients.     

Neoadjuvant and adjuvant chemotherapy with methotrexate, cisplatin and bleomycin for advanced penile cancer: a case report

A 58-year-old male consulted our hospital because of penile swelling and pain with bilateral inguinal lymphadenopathy. Pathological examination of the penile tumor and right superficial inguinal lymph node biopsy demonstrated moderately differentiated squamous cell carcinoma with lymph node metastasis. We diagnosed the tumor inoperable radically and adjuvant chemotherapy with methotrexate, cisplatin and bleomycin was administered, followed by partial penectomy and left superficial lymphadenectomy. The surgical specimens showed few viable tumor cells. This combination chemotherapy is suggested to be effective for the treatment of advanced penile cancer.     

Modified radical inguinal lymphadenectomy for carcinoma of the penis: technique and results

PURPOSE: Modified radical inguinal lymphadenectomy for carcinoma of the penis is presented that satisfies the requirement for complete groin dissection, while significantly decreasing postoperative complications. MATERIALS AND METHODS: Eight patients with squamous cell carcinoma and 2 with leiomyosarcoma of the penis underwent bilateral modified inguinal lymphadenectomy, including removal of the superficial and deep inguinal lymph nodes. To avoid damage to the vessels of the groin region that run parallel to the inguinal ligament and lie in the fat of the superficial layer of the superficial fascia dissection is done beneath this layer. The proper cleavage plane is just above the membranous layer of the superficial fascia, beneath which the superficial inguinal lymph nodes are located. The saphenous vein is preserved and the sartorius muscle is left in situ, so as not to disturb collateral lymphatic drainage. RESULTS: At a followup of 6 to 104 months no skin necrosis, infection or deep venous thrombosis occurred. In 2 patients early moderate lymphedema of the lower extremities resolved with time, 2 had scrotal edema and 3 had a transient lymphocele. CONCLUSIONS: As described, modified radical inguinal lymphadenectomy decreases the morbidity associated with groin dissection, while removing superficial and deep inguinal lymph nodes.     

Morbidity of dynamic sentinel node biopsy in penile carcinoma

PURPOSE: We report on the morbidity of dynamic sentinel lymph node biopsy (DSNB) in penile squamous cell carcinoma (SCC). MATERIALS AND METHODS: Between 1994 and 2003 DSNB was performed in 129 patients with T2 or T3 penile SCC who had 243 clinically node negative groins. Patients with groins with a tumor positive sentinel node underwent additional standard inguinal lymphadenectomy. RESULTS: A total of 285 sentinel nodes were harvested in 223 explored groins. The sentinel nodes were tumor-free in 189 groins. A total of 34 standard inguinal lymphadenectomies were performed because of a tumor positive sentinel node. There were 6 regional relapses during a median followup of 50 months (range 5 to 124) resulting in a false-negative rate of 15% (6 of 40 groins). This rate was 17% when calculated per patient (6 of 35 patients). Early and/or late complications following DSNB only occurred in 7% (14 of 189) of the groins. After DSNB followed by a standard inguinal lymphadenectomy, the rate was 68% (23 of 34). All complications of DSNB were minor and easily managed. CONCLUSIONS: Morbidity of DSNB in penile SCC is low. However, an in field recurrence after a negative DSNB is perhaps the greatest complication of the procedure.     

阴茎癌根治性髂腹股沟淋巴结清扫术的改进

目的:对根治性髂腹股沟淋巴结清扫手术进行改进,以完整清除淋巴结并减少术后并发症。方法:2003~2004年对20例阴茎鳞状细胞癌患者施行根治性腹股沟淋巴结清扫,其中5例还施行了髂淋巴结清扫。腹股沟区的清扫范围包括腹股沟浅组和深组淋巴结,采用暴露好的直切口,皮瓣厚度适中,切断大隐静脉且不转移缝匠肌。髂淋巴结清扫采用下腹正中切口,术后采用逐步降低的负压吸引促进引流和皮瓣愈合。结果:两侧腹股沟区淋巴结平均为21个,阳性淋巴结平均为1.6个。术后病理检查证实55%的患者有淋巴结转移,纠正了40%的术前分期。术后有1例出现高热和局部感染,另有27.5%的单侧腹股沟区域出现局部并发症,包括皮缘坏死、愈合延迟、皮下积液和淋巴瘘。无一例出现大面积皮片坏死和股血管损伤。结论:改进的根治性髂腹股沟淋巴结清扫手术保证了清扫范围,减少了手术并发症。     

Surgical treatment of penile carcinoma: our experience from 1976 to 1997

OBJECTIVE: The purpose of this work is to evaluate our experience with the surgical treatment of penile squamous carcinoma, analyzing the therapeutic results in terms of local recurrence rates, survival and mortality rates. MATERIAL AND METHODS: From 1976 to 1997, 47 patients were treated at our institution for carcinoma of penis. Treatment of primary tumor was conservative in 8 patients (17%). Partial penectomy was performed in 30 patients (63.8%); total penectomy in 5 (10.7%) and emasculation in 4 (8.5%). Pathological stage was pTis in 2 cases (4.2%), pT1 in 20 (42.6%), pT2 in 21 (44. 7%) and pT3 in 4 (8.5%). The tumor was clinically overstaged in 13 patients (27.7%) and understaged in 4 (8.5%). Bilateral inguinal lymphadenectomy was performed only in 4 patients clinically N+ (pN2) and in 3 clinically N0 (pN0). RESULTS: Local recurrence rate was 43% in the patients with pT1 stage tumor treated conservatively. No local recurrence was observed after penectomy. 19 patients (40.4%) are alive and disease-free; 17 patients (36.2%) died of the tumor and 11 patients (23.4%) died of other causes but disease-free. Mean follow-up is 69.43 months. The overall 5-year survival rate was 34%. CONCLUSION: Partial penectomy gives better results than conservative treatment in the local management of the T1 stage tumor. Survival and mortality rates are related to both pathological and histological stages. The high mortality rate observed in the pT2 stage tumors in our experience might be related to the fact that in this stage an inguinal lymphadenectomy was not performed as a rule.     

Morbidity of prophylactic inguinal lymphadenectomy with saphenous vein preservation for squamous cell penile carcinoma

BACKGROUND: Inguinal lymphadenectomy has an essential role in the cure of patients with inguinal metastasis from penile cancer; however, this procedure is associated with a significant morbidity. In recent years, modified lymphadenectomy with saphenous vein preservation has been postulated to reduce morbidity. Herein, we present our recent experience with prophylactic inguinal lymhadenectomy and saphenous vein preservation in patients with invasive penile carcinoma and non-palpable inguinal lymph nodes. METHODS: Seven patients with invasive squamous cell penile carcinoma, who underwent bilateral prophylactic inguinal lymphadenectomy with saphenous vein preservation between 1995 and 2001, were reviewed retrospectively. Mean age was 67.7 years. The pathological stage of the primary tumor was pT2 in four and pT3 in three patients respectively. Postoperative complications were defined as minor--wound infection, seroma formation requiring drainage, and skin necrosis, and major-- deep venous thrombosis, persistent seroma formation, flap necrosis requiring a skin graft, as well as permanent and disabling leg lymphedema. RESULTS: Minimum follow up was 2 years. Minor complications--wound infection--occurred in one patient (one groin). No major complications occurred. All patients are alive without evidence of disease recurrence. CONCLUSIONS: Prophylactic inguinal lymphadenectomy seems to offer reduced morbidity in high risk penile cancer patients without compromising survival outcome.

目的探讨阴茎癌腹股沟淋巴结转移行术前新辅助化疗的临床疗效。方法回顾性分析2001年至2008年收治的13例接受术前新辅助化疗及手术治疗的阴茎癌腹股沟淋巴结转移病例的临床及随访资料,并进行生存分析。结果阴茎癌淋巴结转移13例,均行以顺铂、博来霉素、甲氨蝶呤为主要方案的术前新辅助化疗,其后11例行阴茎部分切除术+单侧或双侧腹股沟淋巴结清扫术,2例行局部放射治疗。从阴茎癌腹股沟淋巴结转移治疗后开始计算生存率,1例失随访。1、2、5年生存率分别为75.0%(9/12)、66.7%(8/12)和41.7%(5/12)。结论对阴茎癌腹股沟淋巴结转移患者采用新辅助化疗结合手术治疗是一种有效的治疗手段。     

Carcinoma uretral primario: resultados de la experiencia de un único centro

Introduction and aim of the studyPrimary urethral carcinoma (PUC) is a rare neoplastic disease arising in the urethra, without any evidence of a previous or synchronous carcinoma of the entire urinary tract. Since rare diseases are often incorrectly diagnosed and managed, the aim of this study was to analyze the experience of a single urology center in the treatment of PUC, focusing on neoplasms arising from the male anterior urethra.Materials and methodsMedical records of patients with neoplasms at the level of the penile and bulbar urethra who presented at our tertiary referral center between January 1988 and December 2018 were retrospectively reviewed. Patients with carcinoma of the prostatic urethra were excluded. The diagnosis was obtained with the aid of urethroscopy and lesion biopsy. Local staging was performed by means of contrast-enhanced MRI in selected patients. Staging was achieved by clinical examination, ultrasonography, and CT scan. Radical surgery (radical cystectomy + total penectomy + bilateral inguinal lymphadenectomy) was proposed to patients with ≥T2 tumors or cN + with a good performance status, proximal tumor and without severe comorbidities. In case of nodal involvement, neoadjuvant chemotherapy was additionally offered. Patients with localized disease (<T2) and/or more distal tumors underwent urethrectomy or partial penectomy. Kaplan-Meier curves were evaluated for analysis of overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS).ResultsA total of 13 male patients with anterior PUC were studied retrospectively. Total penectomy was performed in 7 cases, while partial urethrectomy was performed in 5 cases, and partial penectomy in 1 case. Of the 7 patients who underwent total penectomy, 5 underwent radical cystectomy with bilateral inguinal lymphadenectomy. Three patients were treated with neoadjuvant systemic chemotherapy, of which 2 were cT3N + and 1 was cT3N0. The predominant histologic subtype was squamous cell carcinoma (SCC), found in 7 patients (53.8%), while urothelial carcinoma (UC) was present in 5 patients (38.5%) and a malignant fibro-histiocytoma in 1 case. Most patients were diagnosed at advanced stages of the disease, with T2 tumors in 15.4% and T3 tumors in 46.2% of the cases. Median follow-up was 24 months (range 1–294). After surgical treatment, 8 patients (61.5%) presented disease recurrence after a median of 6.3 months, with a 5-year RFS of 58%±14%. The 5-year OS rate was 50%±14% while the 5-year CSS rate was 66%±13%.ConclusiónGiven its rarity, urethral carcinoma should be treated in a referral center. Treatment options include a radical approach or penile-preserving surgery (urethrectomy or partial penectomy) in cases of localized disease. Due to the high recurrence rate, strict follow-up is mandatory.

Recurrence of bladder cancer in fossa navicularis 12 years after total cystectomy: a case report

We report a case of urothelial cancer recurrence in fossa navicularis of urethra 12 years after total cystourethrectomy for bladder cancer. A 73-year-old man had undergone total cystourethrectomy and ureterocutancostomy for multiple bladder cancer on June 13, 1986. Histopathological findings showed transitional cell carcinoma, G3, pT4 with carcinoma in situ. Twelve years after the cystectomy, he was admitted to our hospital complaining of the induration of the glans penis. Magnetic resonance imaging showed a high intensity tumor in T1-WI and low intensity tumor in T2-WI, which had invaded fossa navicularis of urethra to glans penis. Aspiration biopsy of the penile tumor revealed transitional cell carcinoma. Therefore, we performed partial penectomy on July 16, 1998, since computed tomography showed no lymph node swelling in the inguinal region. Five months after the second operation, he was diagnosed with bilateral inguinal lymph node metastasis. Then we performed 2-course M-VAC (methotrexate, vinblastine, doxorubicin cisplatin) therapy, which showed partial response. Thereafter, bilateral inguinal lymphadenectomy with one-course postoperative M-VAC therapy was performed.     

Multi-institutional long-term experience with conservative surgery for invasive penile carcinoma

PURPOSE: Invasive squamous cell carcinoma of the penis occurs on the glans, prepuce, glans and prepuce, coronal sulcus and shaft. Penile squamous cell carcinoma subsequently invades local structures, corpora cavernosa and the urethra, and metastasizes to the inguinal lymph nodes. Invasive squamous cell carcinoma of the penis usually requires total or partial penectomy. We studied the effect of primary tumor resections tailored to the anatomical extent of the cancer with preservation of uninvolved structures in select patients with invasive penile squamous cell carcinoma. MATERIALS AND METHODS: A total of 30 patients between 39 and 82 years old were treated with unconventional conservative surgical excision of the primary penile lesion. More than 130 patients were excluded from the study because they were treated with partial or total penectomy, Mohs' surgery or more extensive surgery. The 30 patients underwent preoperative biopsy with careful mapping of the extent of the disease. Patient age, tumor extent and grade, operative details, outcome and length of followup were analyzed. RESULTS: Tumor size ranged from 1.5 to 8 cm. in diameter. Tumors were well differentiated in 19 patients, moderately differentiated in 5 and poorly differentiated in 6. A total of 17 patients underwent ilioinguinal lymphadenectomy, 12 of whom had pathologically positive lymph nodes. Inguinal radiation was used in 2 patients. Chemotherapy was given to 7 patients with extensive inguinal lymphadenopathy and to 2 of 5 with pathologically positive lymph nodes. Followup ranged from 12 to 360 months. A total of 21 patients had no evidence of disease at last followup. Tumor resection with no sacrifice of function was performed in 2 patients in whom 3 small recurrences developed. One patient with numerous tumors had 2 small recurrences, which were completely excised with no further recurrence. Of the 7 patients with advanced lymphadenopathy 5 and of 5 patients with pathologically positive lymph nodes at presentation 1 died of the cancer but had no local recurrence in the penis. CONCLUSIONS: In a minority of patients with anatomically suitable penile cancer conservative surgical techniques are safe and provide equal tumor control compared to conventional resections. The anatomical situation and tumor characteristics should dictate the choice of treatment for the primary penile lesion. Inguinal lymph nodes should be managed by appropriately established guidelines but should not influence the extent of primary penile lesion resection.     

A rare case of penile cancer in situ metastasizing to lymph nodes

Penile carcinoma in situ, or Queyrat''s erythroplasia, is a rare condition of the glans penis. This lesion has been associated with invasive squamous cell carcinoma; however, metastasis without an invasive component is extremely rare. There have only been 2 documented cases with metachronous metastases. We report a third case in which metastases were diagnosed at presentation. The patient was a 51-year-old man who presented with a glans penile lesion and bilateral inguinal masses later determined to be carcinoma in situ with metastases to the inguinal and pelvic lymph nodes. He subsequently underwent a partial penectomy and lymphadenectomy followed by adjuvant chemotherapy and radiation. This case is discussed, along with a brief review of the literature.     

Endoscopic lymphadenectomy for penile carcinoma

BACKGROUND AND PURPOSE: Groin dissection remains the gold standard for the treatment of penile carcinoma that has metastasized to the inguinal lymph nodes. However, it is associated with wound-related complications. Modified groin dissection offers a less-radical approach without compromising oncologic outcomes. We present our technique for endoscopic lymphadenectomy for penile carcinoma (ELPC). PATIENTS AND METHODS: Eight patients with clinical stage T(2) N(0-3)M(0) penile carcinoma underwent ELPC. Preoperative Doppler ultrasound mapping of the inguinal lymph nodes and the saphenous vein was performed. RESULTS: Fourteen lymphadenectomies, including superficial with or without deep inguinal and pelvic-node dissection, were completed in eight patients. The median operative time was 91 minutes (range 50-150 minutes), and the mean number of nodes removed was 9 (range 4-15). No perioperative complications occurred. Lymphoceles developed in three groins (23%). No wound-related complications were seen. CONCLUSIONS: The ELPC is a safe and feasible technique that appears to diminish the wound-related complications associated with the standard open approach.
