Radical vulvectomy and bilateral groin lymphadenectomy utilizing separate groin incisions: report of a case with recurrence in the intervening skin bridge

Postoperative wound breakdown is very common following the en bloc dissection of the vulva and inguinal/femoral lymph nodes for carcinoma of the vulva. To decrease the incidence of wound morbidity, techniques have been described for performing the inguinal/femoral lymphadenectomy through separate groin incisions. This approach leaves a bridge of tissue between the vulvar excision and the lymph node dissection. A case of stage I squamous cell carcinoma of the vulva that was treated with a radical vulvectomy and bilateral inguinal/femoral lymphadenectomy utilizing separate groin incisions is presented. This patient later developed a recurrence in the tissue bridge between the vulvar and groin excisions. The mechanism for this recurrence is discussed.     

Morbidity and recurrence with modifications of radical vulvectomy and groin dissection.

Vulvar carcinoma has been managed in recent years with modifications of radical vulvectomy and groin dissection. Separate groin incisions, superficial inguinal lymphadenectomy, unilateral groin dissection, and wide excision have been utilized to reduce the morbidity of treatment. In this study, the surgical management of 82 patients with vulvar squamous cell carcinoma was reviewed in order to assess morbidity and risk of recurrence. A modification of radical vulvectomy and groin dissection was employed in 67 patients, while 15 patients underwent classical en-bloc vulvar and groin dissection. Wound complications of the vulva occurred in 1 of 12 patients undergoing hemivulvectomy, in 8 of 55 undergoing radical vulvectomy, and in 7 of 15 who had en-bloc vulvar resection and groin dissection (P = 0.01). Among the 46 patients undergoing bilateral groin dissection through separate incisions, groin breakdown, lymphocyst, and lymphedema occurred in 10 (22%), 7 (15%), and 7 (15%), versus 0, 1 (7%), and 2 (13%) of the 15 who had unilateral groin dissection. Modification of vulvar resection did not increase the risk of local recurrence. Groin recurrence developed in 2 of 15 patients who underwent en-bloc groin dissection and in 1 of 46 who underwent bilateral groin dissection through separate incisions. Two of 15 who had a unilateral groin dissection recurred in the contralateral groin. The risk of recurrence as well as morbidity following modifications of radical vulvectomy with groin dissection should be considered when planning treatment.     

Robot-assisted Sentinel Lymph Node Mapping and Inguinal Lymph Node Dissection Using Near-infrared Fluorescence in Vulvar Cancer

The surgical treatment of vulvar cancer has undergone many changes over the last century. The morbidity of open inguinal incisions prompts the search for a minimally invasive approach to lymph node dissection. This study reports the outcomes of 4 patients with vulvar cancer undergoing robotic sentinel lymph node (SLN) mapping and lymph node (LN) dissection with near-infrared fluorescence. From 2015 to 2017, 3 patients with squamous cell carcinoma of the vulva underwent robot-assisted SLN mapping and inguinal LN dissection. One patient with a vulvar melanoma had robotic bilateral SLN mapping only. The da Vinci Xi System with Firefly technology (Intuitive Surgical, Sunnyvale, CA) and indocyanine green radiotracer was used in all cases. Eight groins underwent robot-assisted SLN mapping, 6 of which underwent inguinal LN dissection. The average operating time was 234 minutes with vulvectomy. The mean blood loss was 124 mL. The operative time decreased, and the lymph node yield increased with each case. There were no wound separations or long-term negative outcomes, such as persistent lymphedema or recurrence. This case series of robot-assisted SLN mapping and inguinal lymph node dissection shows the safety and feasibility of this new technique in vulvar cancer. It may be a valid approach to reduce short- and long-term morbidity.     

Skin relapse from cervical cancer

BACKGROUND: Different approaches have been attempted in both prophylaxis and treatment of recurrent inguinal lymphoceles; however, to date none have been consistently effective. We hereby report our preliminary experience with mapping of the lymphatic leakage followed by ligation of these mapped vessels for resolution of a recurrent inguinal lymphocele. CASE: A 73-year-old woman underwent an anterior modified radical vulvectomy with bilateral inguinofemoral lymph node dissection due to squamous cell carcinoma of the vulva. Postoperatively she presented with a recurrent inguinal lymphocele unresponsive to several treatment measures. After 8 weeks, the patient underwent lymphatic leakage mapping and subsequent ligation of lymphatic vessel endings, which resolved her recurrent lymphocele. CONCLUSION: Lymphatic mapping and ligation of afferent lymphatics may be a useful method for treating recurrent lymphoceles after inguinofemoral lymph node dissection. Further studies are warranted to prove the absolute efficacy of this technique.     

Carcinoma of the vulva: a retrospective review of 37 cases at a regional cancer centre in South India.

A retrospective review of 37 cases of carcinoma of the vulva presenting between 1996 and 2000 has been carried out. Thirty-three cases were managed with curative intent and four cases with advanced loco-regional disease were managed with palliative intent. The surgical treatment consisted of wide excision in one case, radical vulvectomy (RV) in six cases, radical vulvectomy and bilateral groin node dissection (RV+BGND) in 25 cases and radical vulvectomy and unilateral groin node dissection in one case. Nine of these 33 women also received adjuvant chemotherapy preoperatively in the hope of achieving better tumour-free surgical margins. Eight cases had a partial response and one case achieved complete response; the surgical margins were free in all these patients. One case received neoadjuvant radiotherapy to the vulva and pelvis followed by RV+BGND, which revealed no residual tumour. Overall, 26/33 cases had groin/inguinal node dissection and 23 (88.4%) of them had groin wound dehiscence. Thirteen of these 26 patients (50%) had inguinal node metastases (Stage III, four patients; Stage IV, nine patients). All the patients with negative nodes were free of disease while three of four patients with Stage III and two of nine patients with Stage IV with nodal metastases remained free of disease. The only patient with Stage III disease plus inguinal node metastases who recurred had multiple positive nodes with extracapsular spread. It appears that although bilateral involvement of the inguinal lymph nodes carries a worse prognosis, unilateral involvement with or without vaginal involvement carries an excellent prognosis provided multiple nodes are not involved. The role of neoadjuvant chemotherapy as compared to neoadjuvant radiotherapy, in locally advanced tumours, needs to be explored further.     

Management of vulvar melanoma.

Considerable debate centers on the optimal treatment for vulvar melanoma, as well as those clinicopathological factors influencing prognosis. We reviewed 80 patients with vulvar melanoma seen between 1949 and 1990. Primary tumors were assessed according to Chung (47 patients) and Breslow (65 patients) microstaging systems. Fifty-nine patients (76%) underwent radical vulvectomy, ten patients (13%) had a partial vulvectomy, and nine patients (12%) had a wide local excision. Fifty-six also underwent inguinal node dissection. Median follow-up was 193 months. Median survival was 63 months. Ten-year survival by Chung level was as follows: I 100%; II, 81%; III, 87%; IV, 11%; V, 33%. Ten-year survival by tumor thickness was as follows: 0.75 mm, 48%; 0.75-1.5 mm, 68%; 1.51-3.0 mm, 44%; greater than 3.0 mm, 22%. Increased depth of invasion was associated with increased incidence of inguinal node metastasis. Cox regression analysis demonstrated prognostic significance for tumor thickness (P less than 0.001), inguinal node metastasis (P less than 0.001), and older age at diagnosis (P less than 0.001). Radical vulvectomy did not seem to improve survival over less radical procedures. Based on this experience, we recommend radical local excision for patients with malignant melanoma of the vulva. Patients who have more than a superficially invasive melanoma should also have inguinal lymph node dissection.     

Invasive cervical cancer complicating intrauterine pregnancy: treatment with radical hysterectomy.

OBJECTIVE: Radical hysterectomy and bilateral pelvic lymph node dissection have become the mainstay of treatment for early-stage cervical cancer because of both a high success rate and acceptable morbidity. However, those cervical lesions that occur concomitant with an intrauterine pregnancy have historically been treated with irradiation. We report the morbidity and results of radical hysterectomy and bilateral pelvic lymph node dissection for the treatment of early-stage cervical cancer complicating intrauterine pregnancy. METHODS: Between 1955-1991, 13 patients were treated with radical hysterectomy and bilateral pelvic lymph node dissection with the fetus in situ, and eight others with cesarean delivery followed by radical hysterectomy and bilateral pelvic lymph node dissection. Charts were reviewed retrospectively. RESULTS: Mean operative time was 281 minutes. The mean blood loss was 777 mL with radical hysterectomy and bilateral pelvic lymph node dissection alone, and 1750 mL with cesarean delivery, radical hysterectomy, and bilateral pelvic lymph node dissection (P less than .01). Intraoperative morbidity included a single accidental cystotomy that was complicated in the postoperative period by a vesicovaginal fistula. Fever was the most common postoperative cause of morbidity (29%), while two patients (10%) had wound seromas and a single patient (5%) each had a pulmonary embolism, cystitis, and transfusion-related hepatitis. No perioperative deaths occurred. After documentation of maturity, seven healthy infants were delivered with no major morbidity. Twenty patients (95%) are alive and free of disease with a mean follow-up of 40 months. CONCLUSION: Radical surgery offers immediate treatment for early-stage cervical cancer during intrauterine pregnancy, with low associated morbidity, acceptable survival, and preservation of ovarian function.     

Carcinoma of the vulva. Clinicopathologic factors involved in inguinal and pelvic lymph node metastasis

Eighty-five women with vulvar squamous cell carcinoma were subjected to radical vulvectomy with bilateral inguinal and femoral node dissection or to radical vulvectomy with bilateral inguinofemoral and deep pelvic node dissection. The association between lymph node status (metastatic or not) and several parameters was analyzed: tumor location, size and clinical stage; tumor thickness, histologic grade and mitotic index; blood vessel, lymphatic and perineural infiltration; and lymphocytic and plasma cell infiltrates. There were no metastases to the pelvic lymph nodes without previous inguinal lymph node involvement. Unilateral vulvar carcinomas did not have contralateral metastatic nodes when there was no ipsilateral nodal involvement. Lymphatic vessel infiltration showed a statistically significant correlation with inguinal node metastases (P less than .05). No correlation was found between lymph node metastasis and tumor size, clitoral invasion, tumor thickness, histologic grade, blood vessel and perineural infiltration, lymphocytic and plasma cell infiltrates, and mitotic index.     

Have patients with early squamous carcinoma of the vulva been overtreated in the past? The Norwegian experience 1977-1991

OBJECTIVE: To evaluate different surgical approaches in early squamous vulvar cancer. METHODS: Review of clinical and histopathologic data and follow-up information of 216 patients with clinical FIGO stage I-II disease, primarily treated by surgery from 1977-1991. RESULTS: Eighty-nine patients underwent radical vulvectomy with bilateral groin dissection by en bloc excision, 60 by the triple incision technique, 20 individualized vulvar surgery with uni-or bilateral groin dissection, and 47 vulvar surgery only. Groin metastases occurred in 9% stage I and 25% stage II disease. Groin involvement was not seen in stage I tumors with invasion depth < or =/=1 mm. Bilateral metastases occurred in medially located tumors of both stages, and laterally located stage II. Metastases were ipsilateral in lateral stage 1. Separate groin dissection significantly reduced morbidity. Sixty-six patients relapsed, 14 after more than 5 years. Vulvar recurrence was related to tumor diameter and the condition of the resection borders. The single most important predictor of death from vulvar cancer was the presence of inguinal femoral lymph node metastases. Conservative and individualized surgery did not compromise 5-year survival. CONCLUSIONS: A careful selection of patients fitted for less radical surgery is essential to avoid undertreatment. Groin dissection can be omitted in tumors with diameters < or =/=2 cm and invasion depth < or =/=1 mm. At least ipsilateral groin dissection is needed in all other cases. Groin dissection should be performed through separate incisions. Modified vulvectomy is appropriate provided radicality can be obtained. Long-time follow-up is important as recurrences can be seen many years after primary therapy.     

Prognostic factors in early vulvar cancer

Prognostic parameters were evaluated in 22 patients with small (less than or equal to 2 cm) superficially invasive (less than 5 mm) squamous cell carcinoma of the vulva. Primary surgery included radical vulvectomy with bilateral superficial and deep inguinal lymph node dissection in 11 patients, and wide local excision with ipsilateral superficial inguinal lymph node dissection in 11 patients. Of the 22 patients studied, only 2 (9%) had lymph node metastases. Both patients had a single positive ipsilateral superficial inguinal node. Perineural invasion was strongly associated with lymph node metastases (P less than 0.01). In this group of patients, grade, depth of invasion, lymph-vascular space invasion, and lymphoplasmacytic infiltration were not predictive of lymph node metastases (P greater than 0.05). Two patients initially treated with wide local excision and ipsilateral superficial inguinal lymph node dissection developed recurrent vulvar neoplasia on the contralateral vulva, and both were successfully retreated by wide local excision. All patients are presently alive and well with no evidence of disease. None of the histomorphologic parameters studied were predictive of tumor recurrence. These data suggest that wide local excision with ipsilateral superficial inguinal lymphadenectomy is effective in the treatment of patients with small, superficially invasive carcinomas of the vulva.     

A clinicopathological study of 30 melanomas of the vulva.

Thirty cases of malignant melanomas of the vulva were studied for prognostic factors. Ulceration, tumor thickness, and positive inguinal lymph nodes were the most important prognostic factors. Morphometry did not demonstrate any prognostic meaning. Traditionally a radical vulvectomy and bilateral inguinal lymph node dissection were the therapy of choice, but this treatment modality did not show a better survival than less radical treatment. A low-risk and a high-risk group of patients have been identified for recurrence. The low-risk patient has a nonulcerative tumor, less than 3 mm thick, without clinical evidence of inguinal lymph node metastases, and should be treated by local excision with a 2- to 3-cm margin. The high-risk patient has a tumor which is ulcerative and/or more than 3 mm thick and should also be treated by local excision without elective inguinal node dissection. If clinical suspicion of inguinal lymph node metastases exists, an inguinal node dissection is advocated for better local control of the disease.

Early postoperative discharge following radical vulvectomy and bilateral inguinal lymphadenectomy for vulvar carcinoma

Currently, no robust evidence exists for the optimal period for maintaining the suction drainage in the groin incisions for women who undergo inguinal lymphadenectomy for vulvar carcinoma. In many cases, this may take more than 2 weeks. Some authorities advocate early drain removal at 72 h after surgery, but this approach is associated with increased risk of lymphocyst formation. We attempted to discharge women with suction drains in situ within 48 to 72 h following the surgery. Four patients that underwent vulvectomy and bilateral inguinal lymphadenectomy for vulval cancer were discharged home within 48 to 72 h postoperatively with suction drains in situ. The mean age was 61.5 years. The average number of groin lymph nodes removed was 9.12 per patient. Only one patient had nodes positive for disease (bilaterally). Drains were removed within 7 to 10 days following the discharge. Wound healing was satisfactory in all cases. No cases of wound breakdown were recorded. There was only one case of a small lymphocyst (<3 cm) that resolved spontaneously within 8 weeks. Early postoperative discharge with suction drains in situ appears safe for women that undergo inguinal lymphadenectomy for vulvar carcinoma.     

Minimally invasive vulvar carcinoma: An indication for conservative surgical therapy

It has been proposed that squamous carcinoma of the vulva with 1 mm or less of stromal invasion can be treated with local resection without inguinal node dissection. A retrospective review of 255 cases of stages I and II vulvar carcinoma demonstrated 24 cases of minimally invasive carcinoma. All cases were subjected to detailed chart review and pathologic confirmation. Mean age at diagnosis was 60 years. Seven patients had a preoperative diagnosis of preinvasive disease, ten had stage I disease, and seven had stage II disease. Fifteen cases had associated vulvar carcinoma in situ. Treatment consisted of local excision in 2 patients, radical wide excision in 11, hemivulvectomy in 5, and radical vulvectomy in 6. Eleven patients had either unilateral or bilateral inguinal node dissection. Five-year life-table survival was 89%. Four patients (17%) developed recurrent dysplasia and four (17%) developed invasive recurrences. One invasive recurrence was in an inguinal node in a patient previously treated with a hemivulvectomy and negative ipsilateral superficial node dissection. Univariate analysis revealed no statistically significant associations between recurrence and age, symptom duration, margin status, location, FIGO stage, or coexisting VIN. Large areas of coexisting dysplasia and variable gross appearance make meaningful application of FIGO staging criteria difficult in lesions with minimal focal invasion. Wide excision or radical wide excision of lesions with "high-risk" VIN or those showing less than or equal to 1 mm of stromal invasion on biopsy is adequate therapy. If final pathologic review demonstrates deeper invasion, a selective lymph node dissection can be performed as a second procedure. Careful surveillance with liberal use of colposcopy and biopsies is indicated in these patients.     

Radical wide excision and selective inguinal node dissection for squamous cell carcinoma of the vulva

Limited resection of some vulvar cancers may provide cure rates equivalent to those obtained with radical vulvectomy and bilateral inguinal node dissection. Rapid recovery, fewer complications, and better functional result have been described as advantages to less extensive procedures. Since 1978, 32 patients with invasive squamous cell cancer of the vulva (depth greater than 1 mm) and clinically negative inguinal lymph nodes underwent radical wide excisions as primary therapy. Mean age at diagnosis was 61 years. Seventeen patients had T1 and 15 had T2 tumors. Resection of the primary lesion was tailored to lesion location and size, and dissection was carried to the deep perineal fascia. Twenty-two patients had unilateral superficial inguinal lymph node dissections, five with midline lesions had bilateral superficial dissections, and five had node samplings which included deep inguinal nodes. Depth of invasion ranged from 1.5 to 13.0 mm. Mean largest lesion dimension was 23 mm. Five-year lifetable survival for the entire group was 84%. Univariate analysis of potential prognostic variables showed no significant recurrence or survival differences for patient age (P = 0.56), symptom duration (P = 0.57), FIGO stage (P = 0.67), tumor grade (P = 0.20), tumor location (P = 0.26), depth of invasion (P = 0.56), or resection margin status (P = 0.63). Thirty-one percent of patients had perioperative complications, and 16% developed delayed complications. Mean hospital stay was 10 days. Three patients (10%) developed new or recurrent vulvar disease and underwent additional therapy. None have died of disease, although one is alive with persistent tumor. Radical wide excision and selective inguinal lymphadenectomy constitute a reasonable alternative to radical vulvectomy with bilateral inguinal node dissections for squamous tumors clinically limited to the vulva. Outcome may not be strongly influenced by lesion size or depth of invasion.     

The treatment of lateral T1 and T2 squamous cell carcinomas of the vulva confined to the labium majus or minus

OBJECTIVE: To determine the pattern of lymph node metastases, recurrence rate, and survival of patients with lateral T1 and T2 squamous cell cancer (SCC) of the vulva treated by radical vulvectomy or hemivulvectomy and inguinal lymphadenectomy. METHODS: An institutional review was performed to identify lateral T1 and T2 SCC of the vulva confined to the labium majus and minus. RESULTS: Sixty-one patients with lateral T1 and 61 patients with lateral T2 SCC of the vulva were treated from 1963 to 2003. Radical vulvectomy (RV) was performed in 60 patients, and radical hemivulvectomy (RHV) in 62 patients. Seven of 61 patients (11%) with T1 lesions had ipsilateral superficial inguinal lymph node (SIL) metastases, but none had deep inguinal lymph (DIL) node metastases. Nineteen of 61 patients (31%) with T2 lesions had ipsilateral SIL metastases, and 8 had ipsilateral DIL metastases. No patient had contralateral SIL or DIL metastases. Six patients (10%) with T1 lesions and seven patients (11%) with T2 lesions developed recurrence to the ipsilateral vulva and were treated by re-excision. All patients are alive with no evidence of disease 10-195 months after treatment. One patient with T1 and three patients with T2 SCC developed distant recurrence and died of disease (DOD) 10-15 months after surgery. Disease-free survival of patients with T1 lesions was 98% at 2 years and 98% at 5 years, and with T2 lesions was 95% at 2 years and 93% at 5 years. Local or distant recurrence was not more common in patients treated by RHV than in those treated by RV. CONCLUSION: Lateral T1 and T2 squamous cell cancers of the vulva spread to the ipsilateral inguinal lymph nodes and can be treated effectively with RHV and ipsilateral SIL dissection. Deep inguinal lymphadenectomy is indicated only when the SIL are positive.     

Carcinoma of the vulva (1981-1985): analysis of a radio-surgical approach

Carcinoma of the vulva has recently been the subject of renewed interest of gynecologists and oncologists. That which is commonly defined as the "choice" treatment is a radical vulvectomy with bilateral inguinal lymphadenectomy and, in the case of lymph node metastases, pelvic lymphadenectomy. The usefulness of the pelvic dissection has, however, been disputed and various Authors have proposed an alternative treatment consisting of radical vulvectomy and inguinal lymphadenectomy with external radiotherapy on the inguinal and pelvic lymph nodes, in the case of N+. The present report describes 56 patients with vulvar carcinoma treated at the Regina Elena National Cancer Institute of Rome, 42 of whom were submitted to radical surgery. In 14 of these patients, metastases in the inguinal lymph nodes were found: 10 were submitted to radiotherapy (with TCT or low voltage linear accelerator for a total of 50 Gy over a 5-week period), while the remaining 4 were not treated with any further therapy. Although the survey includes only a limited number of patients, the results obtained certainly favor radio-surgical treatment, also considering data reported in international literature regarding pelvic lymphadenectomy. The actuarial 5-year survival rates for the patients treated with surgery plus radiotherapy is 50% and the recurrence rate is 20%. Although a greater experience is certainly warranted in this field, we believe it may be stated (also on the basis of a recent study conducted by the Gynecologic Oncology Group) that radiotherapy represents a valid alternative to pelvic dissection if an adequate patients selection is made.     

A new approach to vulvar squamous cell carcinoma: two-year follow-up of a case report

BACKGROUND: Vulvar carcinoma is relatively rare gynaecologic malignancy. The most prevalent vulvar cancer is squamous cell carcinoma. It is not uncommon for patients to delay seeking medical attention or for physicians to delay diagnosing the condition. This delay results in many cases being diagnosed in advanced stage. The sentinel lymph node "concept" is attractive in vulvar cancer because it has the potential to avoid a radical vulvectomy associated with uni- or bilateral inguinofemoral lymphadenectomy and, thus, to avoid the morbidity associated with formal groin dissection. CASE REPORT: A case of an 88-year-old woman with advanced local vulvar cancer is presented. A study of the inguinal-femoral lymph nodes was also conducted with intraoperative vital blue dye peritumoral injection and as the sentinel node was found to be negative for malignant metastasis, a radical vulvectomy without bilateral inguinofemoral lymphadenectomy and without additional treatment (chemotherapy and/or radiotherapy) was performed. Follow-up was performed at one, three, six, nine, 12, 18 and 24 months. No local recurrence or distant metastasis was found. CONCLUSION: The sentinel lymph node procedure allows a less aggressive treatment to be carried out in patients with invasive vulvar cancer thus reducing the complications and morbidity of treatment. Moreover, reducing the operative stress can change the overall survival and reduce the mortality linked to complications and postoperative stress.     

Zinc sulfate: An adjuvant to wound healing in patients undergoing radical vulvectomy

The average postoperative stay for 45 patients undergoing radical vulvectomy with femoral and inguinal lymphadenectomy was 37 days. Five patients were treated with oral zinc sulfate for at least 7 days prior to surgery. The incidence of wound infection was decreased, and the average postoperative stay was reduced to 18 days.     

En bloc radical vulvectomy and lymphadenectomy with modifications of separate groin incisions.

A new modification of radical vulvectomy and lymphadenectomy through separate groin incisions involves dissection of the intervening skin bridge and allows an en bloc dissection. The results in 26 women treated with this technique are compared with those of seven treated with separate incisions without an en bloc dissection. All 33 women had squamous carcinoma of the vulva and were treated between 1985-1989. The incidence of advanced disease was high, with nodal metastases present in 52% of cases. Dissection of the tissue beneath the skin bridge did not alter the morbidity of the procedure in terms of the incidence of wound infection, number of units of blood transfused, or duration of hospitalization. The only case of an isolated recurrence in the skin bridge occurred in a woman who did not have an en bloc dissection, although there was no significant difference in the overall local recurrence rate between the groups. Further evaluation with larger numbers is required, but we suggest that an en bloc dissection using separate incisions may reduce the risk of isolated recurrence in the skin bridge, particularly in patients with advanced disease.
