Contemporary morbidity from lymphadenectomy for penile squamous cell carcinoma: the M.D. Anderson Cancer Center Experience

PURPOSE: Inguinal lymphadenectomy can be curative in patients with small volume inguinal metastases and those with more significant adenopathy responding to combination chemotherapy. However, several series collected for 15 to 40 years attest to the significant morbidity associated with lymphadenectomy. We reviewed our recent experience with lymphadenectomy in patients with invasive penile cancer who were judged to require inguinal staging and therapeutic procedures to assess the incidence and magnitude of complications caused by this procedure, especially in those with no palpable adenopathy (prophylactic group). MATERIALS AND METHODS: A total of 106 lymphadenectomy procedures were performed in 53 patients. The indications for dissection were prophylactic in 66 (62%) patients in whom a superficial dissection alone was completed on the ipsilateral side, therapeutic in 28 (26%) in whom superficial, deep and ipsilateral pelvic dissections were performed, and palliative in 12 (11%) undergoing extensive resection of inguinal and abdominal wall tissue after chemotherapy. Minor postoperative complications included those requiring local wound débridement in the clinic, mild to moderate leg edema, seroma formation not requiring aspiration and minimal skin edge necrosis requiring no therapy. Major complications included severe leg edema interfering with ambulation, skin flap necrosis requiring a skin graft, rehospitalization, deep venous thrombosis, death, or reexploration or other invasive procedures performed in the operating room. The incidence and magnitude of complications were compared with prior reports from our center and other series. RESULTS: A total of 41 (68%) minor and 19 (32%) major complications occurred with the 106 dissections (31 of 53 patients, 58%). Prophylactic and therapeutic dissections were associated with a lower incidence of complications compared with palliative dissections (p = 0.017 to 0.049). The incidence of major complications also trended lower in the prophylactic group compared with other indications (p = 0.05). One patient in the palliative group died of sepsis on postoperative day 15. When compared with 3 prior series, the incidence of skin edge necrosis in our series was significantly lower (8% versus 45% to 62%, p <0.0001). Similarly, the incidence and severity of edema in our series were significantly lower than in a prior report from our institution (23% versus 50%, p <0.0001). CONCLUSIONS: For select patients undergoing prophylactic inguinal dissection to detect the presence of microscopic metastases, the incidence and magnitude of complications appeared acceptable in our contemporary experience. Similarly the morbidity of therapeutic lymphadenectomy appeared acceptable, considering the potential therapeutic benefit. However, significant complications, including death, can be associated with palliative groin dissection. Optimal candidates are those having a significant response to systemic chemotherapy whose groins are grossly uninfected.     

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.

Inguinofemoral dissection for carcinoma of the vulva: effect of modifications of extent and technique on morbidity and survival

BACKGROUND: The aim of this study was to evaluate the impact of modifications of extent (medial inguinal and medial femoral lymphadenectomy, inguinal lymphadenectomy, inguinal and medial femoral lymphadenectomy, and inguinofemoral lymphadenectomy) and surgical technique of lymphadenectomy (including sartorius transposition, preservation of the fascia lata, and preservation of the saphenous vein) on morbidity, groin recurrence, and survival in patients with vulvar carcinoma. STUDY DESIGN: A retrospective review of 194 patients with primary squamous cell cancer of the vulva was conducted. Clinical, surgical, histopathologic, postoperative short- and longterm complications, and followup data were collected from patient records. RESULTS: Inguinal lymphadenectomy and medial inguinal and medial femoral lymphadenectomy produced about half fewer nodes than did other surgical procedures. On the other hand, number of lymph nodes removed did not differ notably between inguinofemoral lymphadenectomy and inguinal and medial femoral lymphadenectomy. Logistic regression showed that obesity was associated with increased risk of cellulitis. Age greater than 70, obesity, and extent of lymphadenectomy increased wound breakdown risk. Factors associated with leg edema persisting for more than 6 months were: extent of lymphadenectomy, sartorius transposition, and adjuvant irradiation of groin area. With a mean followup time of 38 months, neither groin recurrence rate nor disease-specific survival markedly differed according to technique of lymphadenectomy. CONCLUSION: Techniques of lymphadenectomy with preservation of fascia lata and saphenous vein are associated with a decreased risk of postoperative morbidity without jeopardizing outcomes.

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.     

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.

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.

Key factors in reducing morbidity following inguinal node dissections

Background

Inguinal node dissection is associated with high incidence of post-operative morbidity.

Methods

We conducted a retrospective review of all patients who underwent inguinal node dissection at The Christie Hospital between 2001 and 2008. Two hundred thirty two patients undergoing 247 inguinal node dissection outcomes were assessed with a median follow-up of 29 months (range 5 to 75).

Results

Our overall complication rate was 61 %. Our wound infection rate is 34 % with 10 % wound necrosis, 25 % wound breakdown, 35 % seroma, 23 % lymphoedema and 0.4 % haematoma rate. The overall and individual complication rate, including infection wound breakdown, skin necrosis, seroma formation and lymphoedema, was significantly lower with use of a transverse incision for access compared to using a Lazy S and longitudinal incisions (P?<?0.008 and P?<?0.0001, respectively). Patients undergoing Sartorius switch had a reduced rate of seroma formation (P?=?0.018). The preservation of the long saphenous veins was also associated with a reduction on the overall complication rate (P?=?0.007).

Conclusions

Inguinal node dissection postoperative complications are reduced by transverse incision, Sartorius switch and preservation of the long saphenous vein. Level of Evidence: Level IV, prognostic/risk study.

Long-term followup of penile carcinoma treated with penectomy and bilateral modified inguinal lymphadenectomy

PURPOSE: We evaluated modified inguinal lymphadenectomy in the treatment of penile carcinoma, analyzing the rate of complications compared to complete inguinal lymphadenectomy, the complications in performing lymphadenectomy and penectomy concomitantly, and the long-term locoregional recurrence rate. MATERIALS AND METHODS: A total of 26 patients with squamous cell carcinoma of the penis were clinically assessed, and underwent penectomy and bilateral modified inguinal lymphadenectomy at the same operative time. Frozen section analysis of lymph nodes was performed and if metastases were detected a complete ipsilateral inguinal dissection was performed. RESULTS: A total of 52 modified lymphadenectomies were performed. In 10 procedures lymph node metastasis was present. Clinical staging presented false-positive and false-negative rates of 50% and 7.9%, respectively. The complication rate for modified lymphadenectomy was 38.9% and for complete inguinal lymphadenectomy it was 87.5%. Followup ranged from 5 to 112 months and mean followup of recurrence-free cases was 78 months (range 38 to 112). A total of 18 patients underwent bilateral negative modified inguinal lymphadenectomy and 2 of these experienced locoregional recurrence within 2 years after surgery. CONCLUSIONS: Modified inguinal lymphadenectomy causes a lower complication rate than complete inguinal lymphadenectomy. Bilateral modified inguinal lymphadenectomy performed at the same time as penectomy does not increase the complication rate. When frozen section analysis is negative bilaterally, 5.5% of inguinal regions might still harbor occult metastasis. Modified inguinal lymphadenectomy is recommended as a staging procedure in all patients with T2-3 penile carcinoma. A straight followup is required for 2 years since all recurrence was within this period.
