Gluteal Fold V-Y Advancement Flap for Genital Reconstruction following Radical Vulvectomy with Bilateral Inguinofemoral Lymphadenectomy in Vulvar Cancer: A Case Report

Background: Vulvar cancer is a rare malignancy representing about 4% of all genital cancers in women. Historically, the gold standard for treatment of squamous cell carcinoma of the vulva was en bloc radical vulvectomy with bilateral inguinofemoral lymphadenectomy. For the reconstruction the options are primary closure, skin grafts, or local and distant flaps. In this case we used the gluteal fold fasciocutaneous V-Y advancement flap that is sensate and thin with a reliable blood supply, can be advanced easily, and can be performed in a single-stage procedure. Care Report: We present a clinical case of an 82- year old female patient who had an exophytic vulvar lesion, which grew progressively with the histopathologic diagnosis of invasive vulvar squamous cell carcinoma. It was decided to perform radical vulvectomy with right unilateral lymphadenectomy and reconstruction with Gluteal Fold V-Y Advancement Flap. During the post-surgical period it recurred with wound dehiscence and finally skin necrosis developed in the area of the left thigh. Surgical debridement, escharectomy, harvesting and application of skin graft, and closure of the femoral hernia with omentum patch were performed with no associated complications. Follow-up was carried out during the next 3 months after surgery. She presented adequate evolution of the flap and left thigh area. Conclusions: The Gluteal Fold V-Y Advancement Flap is an excellent option for the reconstruction of the vulvovaginoperineal area after a radical vulvectomy. It provides us with a good prognosis and quality of life for the patient. Article Details Issue

Pelvic lymphadenectomy in vulvar cancer and its impact on prognosis and outcome

BackgroundThe value of pelvic lymphadenectomy (LAE) has been subject of discussions since the 1980s. This is mainly due to the fact that the relation between lymph node involvement of the groin and pelvis is poorly understood and therewith the need for pelvic treatment in general.Patients and MethodsN = 514 patients with primary vulvar squamous cell cancer (VSCC) FIGO stage ≥ IB were treated at the University Medical Center Hamburg-Eppendorf between 1996 and 2018. In this analysis, patients with pelvic LAE (n = 21) were analyzed with regard to prognosis and the relation of groin and pelvic lymph node involvement.ResultsThe majority had T1b/T2 tumors (n = 15, 78.9%) with a median diameter of 40 mm (11–110 mm). 17/21 patients showed positive inguinal nodes. Pelvic nodal involvement without groin metastases was not observed. 6/17 node-positive patients with positive groin nodes also had pelvic nodal metastases (35.3%; median number of affected pelvic nodes 2.5 (1–8)). These 6 patients were highly node positive with median 4.5 (2–9) affected groin nodes. With regard to the metastatic spread between groins and pelvis, no contralateral spread was observed. Five recurrences were observed after a median follow-up of 33.5 months. No pelvic recurrences were observed in the pelvic nodal positive group. Patients with pelvic metastasis at first diagnosis had a median progression-free survival of only 9.9 months and overall-survival of 31.1 months.ConclusionA relevant risk for pelvic nodal involvement only seems to be present in highly node-positive disease, therefore pelvic staging (and radiotherapy) is probably unnecessary in the majority of patients with node-positive VSCC.

Comparison of the two routes of video endoscopic inguinal lymphadenectomy in vulvar cancer: a systematic review and a single-center experience.

BackgroundVideo endoscopic inguinal lymphadenectomy (VEIL) has fewer complications than open surgery for vulva cancer. No high-level evidence comparing the efficacy and safety of the two routes of VEIL (VEIL-H and VEIL-L) is available.MethodsWe performed a comprehensive literature search for reports on VEIL for vulva cancer from 2000 to 2020 and reviewed our experience. Data extraction includes patients’ characteristics, perioperative indicators, postoperative complications, and cancer recurrence.ResultsA total of 11 eligible studies were included in the systematic review. Nine studies included only one route of VEIL, and the other two studies directly compared the two routes of VEIL. The average operation time of the VEIL-L group was 85 (range, 33–180.12) minutes, and that of the VEIL-H group was 112 (range, 35–170.79) minutes. The average blood loss of the VEIL-L group was 9 (range, 5–30) mL, and that of the VEIL-H group was 96 (range, 5.5–214.8) mL. The average number of intraoperatively removed lymph nodes in the VEIL-L group was 9 (range, 7.5–13.2), and that in the VEIL-H group was 14 (range, 9.5–16). No significant difference was observed in the cancer recurrence rate between the two groups. We found similar results in our cohort study.ConclusionsThe operation time, intraoperative blood loss, and time of drainage of the VEIL-L procedure seemed less than those of the VEIL-H procedure. VEIL-L and VEIL-H were equivalent in the efficacy of lymph node dissection, surgery-related complications, and cancer recurrence rate.

Pelvic Lymphadenectomy in Vulvar Cancer - Does it make sense?

Since the publication of the updated German guideline in 2015, the recommendations for performing pelvic lymphadenectomy (LAE) in patients with vulvar cancer (VSCC) have changed considerably. The guideline recommends surgical lymph node staging in all patients with a higher risk of pelvic lymph node involvement. However, the current data do not allow the population at risk to be clearly defined, therefore, the indication for pelvic lymphadenectomy is still not clear. There are currently two published German patient populations who had pelvic LAE which can be used to investigate both the prognostic effect of histologically verified pelvic lymph node metastasis and the relation between inguinal and pelvic lymph node involvement. A total of 1618 patients with primary FIGO stage ≥ IB VSCC were included in the multicenter AGO CaRE-1 study (1998 – 2008), 70 of whom underwent pelvic LAE. During a retrospective single-center evaluation carried out at the University Medical Center Hamburg-Eppendorf (UKE), a total of 514 patients with primary VSCC treated between 1996 – 2018 were evaluated, 21 of whom underwent pelvic LAE. In both cohorts, around 80% of the patients who underwent pelvic LAE were inguinally node-positive, with a median number of three affected groin lymph nodes. There were no cases of pelvic lymph node metastasis without inguinal lymph node metastasis in either of the two cohorts. Between 33 – 35% of the inguinal node-positive patients also had pelvic lymph node metastasis; the median number of affected groin lymph nodes in these patients was high (> 4), and the maximum median diameter of the largest inguinal metastasis was > 40 mm in both cohorts. Pelvic lymph node staging and pelvic radiotherapy is therefore probably not necessary for the majority of node-positive patients with VSCC, as the relevant risk of pelvic lymph node involvement was primarily found in node-positive patients with high-grade disease. More, ideally prospective data collections are necessary to validate the relation between inguinal and pelvic lymph node involvement.

Do Groin Drains Reduce Postoperative Morbidity in Women Undergoing Inguinofemoral Lymphadenectomy for Vulvar Cancer?

Sentinel lymph node biopsy has been widely adopted in the surgical management of women with early-stage vulvar cancer, but many patients require inguinofemoral lymphadenectomy (IFL). Following IFL, many surgeons drain the groin to prevent lymphocyst formation despite a lack of evidence to support this practice. Our objective was to investigate whether groin drains after IFL are associated with reduced postoperative morbidity in women undergoing surgery for vulvar cancer. A retrospective cohort study of women diagnosed as having primary vulvar cancer who underwent vulvectomy/radical local excision and unilateral or bilateral IFL was conducted. Cases were ascertained from the weekly outcome reports of a statewide tertiary gynecologic oncology tumor board. Data including postoperative outcomes were abstracted from medical records. Patients were stratified into 1 of 2 groups according to whether a groin drain had been used. Seventy-one patients were included. Inguinal drains were used in 48 patients (67.6%) and 23 patients (32.4%) did not have their groin wound(s) drained. The most common postoperative complications recorded were wound infection (59.2%), groin lymphocyst (32.4%), and cellulitis (25.4%). The mean length of hospital admission was 11.5 days (2-40 days). Compared with patients in whom inguinal drains were placed, those in the "no drain" group had a significantly lower incidence of postoperative groin cellulitis (8.7% vs 25.4% P = 0.039). No significant differences were observed between patients in the "drain" and "no drain" groups in lymphocyst formation, wound infection, return to the operating room, duration of hospital stay, readmission post-discharge, and lower-limb lymphedema. In this study of patients undergoing inguinofemoral dissection for primary vulvar cancer, postoperative cellulitis occurred less frequently in patients without an inguinal drain. The incidence of other postoperative complications was no different whether or not a groin drain was used. Prospective studies may be warranted.

Feasibility and Safety of Video Endoscopic Inguinal Lymphadenectomy in Vulvar Cancer: A Systematic Review.

ObjectiveTo systematically review previous studies and to evaluate the feasibility and safety of video endoscopic inguinal lymphadenectomy (VEIL) in vulvar cancer.MethodsWe conducted a comprehensive review of studies published through September 2014 to retrieve all relevant articles. The PubMed, EMBASE, Web of Science, Cochrane Library, Wan Fang Data and Chinese National Knowledge Infrastructure databases were systematically searched for all relevant studies published in English or Chinese through September 2014. Data were abstracted independently by two reviewers, and any differences were resolved by consensus.ResultsA total of 9 studies containing 249 VEIL procedures involving 138 patients were reviewed. Of the 249 VEIL procedures, only 1 (0.4%) was converted to an open procedure for suturing because of injury to the femoral vein. The range of operative time was 62 to 110 minutes, and the range of estimated blood loss was 5.5 to 22 ml. The range of the number of harvested lymph nodes was 7.3 to 16. The length of hospital stay varied from 7 to 13.6 days across reports. The incidence of lymph node metastasis was 19.7% (27/138), and the recurrence rate was 4.3% (3/70) within 3 to 41 months of follow-up. One or more short-term complications were documented in 18 of 138 (13.0%) patients. Complications after VEIL were observed in 14 (10.13%) patients and in 15 (6.0%) of the VEIL cases, including major lymphocyst formation in 9 (3.6%), lymphorrhea in 2 (0.8%), inguinal wound infection without wound breakdown in 3 (1.2%) and lymphedema in 1 (0.4%).ConclusionsVEIL appears to be a feasible procedure in the management of vulvar cancer. There may be potential benefits that result in lower morbidity compared to traditional methods, but this has yet to be objectively proven.

Does the count after inguinofemoral lymphadenectomy in vulvar cancer correlate with outcome?

BackgroundInguinal lymph node (LN) metastasis is an important prognostic factor in vulvar cancer. Our aim was to determine the prognostic value of the number of resected LNs in inguinofemoral lymphadenectomy. MethodsA retrospective analysis was performed in a series of 158 individuals who underwent bilateral inguinofemoral lymphadenectomy for vulvar squamous cell carcinoma from January 1980 to February 2010. ResultsThe mean age was 67 years (range: 15–90). Median tumor size was 5cm (range: 1–18). A median of 22.5 inguinal LNs (range: 2–57) was resected. Thirteen (8.2%) patients had <12 LNs resected, and 145 (91.8%) had ≥12 LNs resected. Eighty (50.6%) patients had LN metastasis, with a median of 2 positive LNs (range: 1–16). Of those with positive LNs, 19 (23.8%), 23 (28.8%), and 38 (47.5%) patients had 1, 2, and 3 or more positive LNs, respectively. Thirty-three (41.2%) patients had bilateral LN metastasis. For patients without LN involvement, we failed to observe any significant difference between patients with <12 LNs and ≥12 LNs that were resected with regard to risk of recurrence (p=0.97) and death from cancer (p=0.43) in 5 years. However, resection of <12 LNs in patients with positive LNs negatively impacted the risk of recurrence (p=0.003) and death from cancer (p=0.043). ConclusionsResection of fewer than 12 LNs in vulvar cancer has a negative impact on outcome for patients with positive inguinal LNs.

Lower Extremity Glandography (LEG): A New Concept to Identify and Enhance Lymphatic Preservation

Lower extremity edema remains a major postoperative complication after inguinal lymphadenectomy for vulvar cancer. This study documents the lymphatic drainage of the vulva versus the lymphatic drainage of the lower extremity coming through the femoral triangle. Seven patients underwent either unilateral or bilateral inguinal lymphadenectomy in conjunction with a radical vulvar resection. Preoperatively, patients had technetium-99 injected into the vulvar cancer. Isosulfan blue was injected into the medioanterior thigh 10 cm below the inguinal ligament. The femoral triangle was opened, and a neoprobe was used to locate the "hot" node bearing the technetium-99. Gentle dissection located the blue lymphatic channel and any blue lymph nodes. The blue and hot nodes were resected and submitted separately. The patients then underwent a complete inguinal lymphadenectomy. A total of 11 groin dissections were performed. In 9 of the 11 groins, the hot node was identified, and in 8 of the 11 groins, blue node or lymphatic channel was identified. The hot nodes were uniformly located on the superior medial aspect of the femoral triangle. The blue nodes were uniformly located on the lateral aspect of the femoral triangle just anterior to the femoral artery or vein. Three patients had hot lymph nodes containing cancer. Of those 3 patients, one had an additional node positive. None of the blue lymph nodes contained cancer. This procedure demonstrates the alternative lymphatic drainage of the leg versus the vulva. Larger studies are necessary to document the exclusivity of these 2 drainage systems. Preservation of the lymphatic drainage of the leg may result in decreased lymphedema.

Comparison of outcome and recurrence-free survival after sentinel lymph node biopsy and lymphadenectomy in vulvar cancer

Objectives Lymph node status is an important prognostic factor in patients with squamous cell carcinoma (SCC) of the vulva. Complete inguinofemoral lymph node dissection (ILND) is accompanied by a high morbidity. Sentinel lymph node biopsy (SLNB) was established for less invasive lymph node (LN) staging. The aim of this study was to evaluate safety of SLNB in terms of accuracy and outcome in a clinical routine setting. Methods We retrospectively reviewed the data of patients who underwent SLNB and/or ILND for vulvar SCC in the years 1990–2007. Clinical follow-up was evaluated for histological nodal-negative patients with tumor stage T1 or T2. The false negative rate of SLNB was determined in patients who underwent both SLNB and ILND. Results Preoperative sentinel lymph node (SLN) visualization by scintigraphy was successful in 95% of all patients. SLNB was false negative in 1/45 inguinae (2.2%). All SLN were detected intraoperatively. During the follow-up period (median 24 months for SLNB and 111 months for ILND), no groin recurrences in initially nodal negative patients occurred ( n = 34, 59 inguinae). Transient lymph edema occurred in 7/18 patients after ILND (39%) and 2/16 patients (13%) after SLNB. No persistent edemas were found after SLNB and ILND. Conclusion According to our experience SLNB is feasible and accurately predicts LN status of vulvar SCC under clinical routine conditions. SLNB in vulvar cancer seems to be a safe alternative to ILND in order to reduce morbidity of surgical treatment.

A gelatin matrix-thrombin tissue sealant (FloSeal®) application in the management of groin breakdown after inguinal lymphadenectomy for vulvar cancer

The rate of groin breakdown after radical wide vulvar excision and inguinal lymphadenectomy for vulvar cancer remains significant despite conservative surgical approaches. An 86-year-old Latin American woman underwent wide radical excision and bilateral inguinal lymphadenectomy for vulvar cancer. The postoperative course was complicated by bilateral groin wound separation and high output lymphorrhea. The patient responded to the application of a gelatin matrix-thrombin tissue sealant (FloSeal®) to the bases of each groin with resolution in lymphorrhea and formation of granulation tissue. The application of a gelatin matrix-thrombin tissue sealant (FloSeal®) may be a viable treatment in the management of groin breakdown in selected patients when conventional therapy produces suboptimal results.

Rationale and definition of the lateral extension of the inguinal lymphadenectomy for vulvar cancer derived from an embryological and anatomical study.

The objective of the present study was to define the location of the most lateral superficial inguinal node lying along the inguinal ligament, through an embryological and anatomotopographical study, in order to rationalize the lateral extension of the groin lymphadenectomy in vulvar cancer. Sections of the upper portion of the femoral triangle belonging to three human fetuses, whose crown-rump (CR) length ranged from 70 to 310 mm, corresponding to a developmental age of 11 and 35 weeks, were studied. In addition, for an objective topographical evaluation of the disposition of the superficial inguinal lymph nodes, adult cadavers photographs of dissected Scarpa's triangle, reported in anatomical atlases, were analyzed. Both the embryological investigation and the anatomotopographical evaluation on cadavers photographs demonstrate that the most lateral superficial inguinal lymph node does not rise above the medial margin of the sartorius muscle, nor far lateral to the point where the superficial circumflex iliac vessels cross the inguinal ligament. On the basis of the present study, the authors believe that the superficial circumflex iliac vessels could represent the lateral surgical landmark, easily detectable, at which the inguinal lymphadenectomy should cease. Therefore, there is no need to extend the lateral excision to the anterior superior iliac spine. Finally, leaving the fatty tissue laterally to these vessels, some lymphatic channels could be preserved, decreasing the incidence and the entity of wound seroma and lymphedema.
