General Information About Vulvar Cancer

This summary addresses squamous cell cancer of the vulva and vulvar intraepithelial neoplasias (VIN), some of which are thought to be precursors to invasive squamous cell cancers.

The labia majora are the most common sites of vulvar carcinoma involvement and account for about 50% of cases. The labia minora account for 15% to 20% of vulvar carcinoma cases. The clitoris and Bartholin glands are less frequently involved.[ 1 ] Lesions are multifocal in about 5% of cases. More than 90% of invasive vulvar cancers are squamous cell carcinomas.[ 2 ]

Incidence and Mortality

Vulvar cancer accounts for about 4% of cancers of the female genital system in the United States.[ 2 ]

Estimated new cases and deaths from vulvar cancer in the United States in 2020:[ 3 ]

Anatomy

The vulva is the area immediately external to the vagina, including the mons pubis, labia, clitoris, Bartholin glands, and perineum.

Anatomy of the vulva; drawing shows the mons pubis, clitoris, urethral opening, inner and outer lips of the vagina, and the vaginal opening. Also shown are the perineum and anus.

Clinical Features

Women with VIN may not present with symptoms at diagnosis.

Possible signs and symptoms of invasive squamous cell cancers of the vulva include the following:

Diagnostic and Staging Evaluation

The following procedures may be used to diagnose and stage vulvar cancer:

Prognosis

Prognosis depends on the pathologic status of the inguinal lymph nodes and whether spread to adjacent structures has occurred.[ 8 ] In patients with operable disease without lymph node involvement, the overall survival (OS) rate is 90%; however, in patients with nodal involvement, the 5-year OS rate is approximately 50% to 60%.[ 9 ]

The size of the primary tumor is less important in defining prognosis.[ 8 ]

Follow-up After Treatment

Invasive and preinvasive neoplasms of the vulva may be HPV-induced and the carcinogenic effect may be widespread in the vulvar epithelium. As a result, patients are monitored regularly for signs or symptoms of recurrence.

Stage Information for Vulvar Cancer

Staging evaluation for vulvar cancer includes the following, as needed:

Suspected bladder or rectal involvement must be confirmed by biopsy.[ 1 ]

The Fédération Internationale de Gynécologie et d’Obstétrique (FIGO) Staging

FIGO and the American Joint Committee on Cancer have designated staging to define vulvar cancer; the FIGO system is most commonly used.[ 1 ][ 2 ] Stage is based on pathology staging at the time of surgery or before any radiation or chemotherapy, if they are the initial treatment modalities.[ 3 ]

The staging system does not apply to malignant melanoma of the vulva, which is staged like melanoma of the skin.[ 1 ]

bThe depth of invasion is defined as the measurement of the tumor from the epithelial-stromal junction of the adjacent most superficial dermal papilla to the deepest point of invasion.
I Tumor confined to the vulva.
IA Lesions ≤2 cm in size, confined to the vulva or perineum and with stromal invasion ≤1.0 mmb, no nodal metastasis.
IB Lesions >2 cm in size or with stromal invasion >1.0 mmb, confined to the vulva or perineum, with negative nodes.

IVA(ii) Fixed or ulcerated inguinofemoral lymph nodes.
IVB Any distant metastasis including pelvic lymph nodes.

Grade is reported in registry systems and may differ between systems; a two-, three-, or four-grade system may be applied. If not specified, the following system is generally used:[ 1 ]

Overall, about 30% of patients with operable disease have lymph node spread. The pattern of spread is influenced by the histology. Risk factors for lymph node metastasis include the following:[ 4 ][ 5 ][ 6 ][ 7 ][ 8 ]

Well-differentiated lesions tend to spread along the surface with minimal invasion, whereas anaplastic lesions are more likely to be deeply invasive. Spread beyond the vulva is either to adjacent organs such as the vagina, urethra, and anus, or via the lymphatics to the inguinal and femoral lymph nodes, followed by the deep pelvic nodes. Hematogenous spread appears to be uncommon.

Treatment Option Overview for Vulvar Cancer

Standard primary treatment for vulvar cancer is surgery. Radiation therapy is also given to patients with stage III or IV disease.[ 1 ][ 2 ][ 3 ] Newer strategies have integrated surgery, radiation therapy, and chemotherapy and tailor the treatment to the extent of clinical and pathologic disease. Patterns of practice in combining these treatments vary.[ 4 ]

Because there are few patients with advanced disease (stages III and IV), only limited data are available on treatment efficacy in this setting, and there is no standard chemotherapy regimen for these patients. Physicians may offer eligible patients with stage III or IV disease participation in clinical trials.

Information about ongoing clinical trials is available from the NCI website.

Surgery

Surgical resection

Since the 1980s, the trend of surgical resection in patients with vulvar cancer has been toward more limited surgery, often combined with radiation therapy to minimize morbidity.[ 5 ] In tumors clinically confined to the vulva or perineum, radical local excision with a margin of at least 1 cm has generally replaced radical vulvectomy; separate incision has replaced en bloc inguinal lymph node dissection; ipsilateral inguinal node dissection has replaced bilateral dissection for laterally localized tumors; and femoral lymph node dissection has been omitted in many cases.[ 2 ][ 5 ][ 6 ][ 7 ] However, the different surgical techniques have not been directly compared in randomized controlled trials. In addition, nonrandomized studies lack uniform staging definitions and clear descriptions of lymph node dissection or ancillary radiation.[ 8 ][Levels of evidence: 3iiiDii and 3iiiDiv] The evidence base is therefore limited.

Sentinel lymph node dissection (SLND)

Another strategy to minimize the morbidity incurred by groin lymph node dissection in patients with early clinical-stage disease is SLND, reserving groin dissection for those with metastases to the sentinel node(s).

Evidence (SLND):

  1. In a multicenter case series, 403 patients with primary vulvar squamous cell cancers smaller than 4 cm and clinically negative groin lymph nodes underwent 623 SLNDs (using radioactive tracer and blue dye for sentinel node identification).[ 9 ] All patients had radical resection of the primary tumor. Node metastases were identified in 26% of SLND procedures, and these patients went on to full inguinofemoral lymphadenectomy. The patients with negative sentinel nodes received no further therapy. After two local recurrences in 17 patients with multifocal primary tumors, the protocol was amended to allow only patients with unifocal tumors into the study.[ 9 ][Level of evidence: 3iiiDiv]

SLND may be useful when performed by a surgeon experienced in the procedure, and it may avoid the need for full groin lymph node dissection or radiation in patients with clinically nonsuspicious lymph nodes.

Radiation Therapy

Radical radiation therapy can be used for patients unable to tolerate surgery or when surgery is not an option because of the site or extent of disease.[ 10 ][ 11 ][ 12 ][ 13 ]

Groin lymph node metastases are present in approximately 20% to 35% of patients with tumors clinically confined to the vulva and with clinically negative nodes.[ 9 ][ 14 ] Lymph node dissection is traditionally part of the primary surgical therapy in all but the smallest tumors. Some investigators recommend radiation therapy as a means to avoid the morbidity of lymph node dissection, but it is not clear whether radiation therapy can achieve the same local control rates or survival rates as lymph node dissection in early-stage disease.

Localized node-negative disease

A randomized trial to address the efficacy of radiation therapy in patients with clinically localized vulvar cancer has been reported.[ 14 ][ 15 ] In that study, women with disease clinically confined to the vulva, who did not have clinically suspicious groin lymph node metastases, underwent radical vulvectomy followed by either groin radiation (50 Gy at 2 Gy per fraction) or groin dissection (plus groin radiation if nodes were pathologically involved). Although the planned accrual was 300 patients, the study was stopped after 58 women were randomly assigned to it because of worse outcomes in the radiation therapy arm.

In summary, the trial was stopped prematurely, and little can be said about the relative efficacy of the two treatment approaches.[ 14 ]

Pelvic node–positive disease

Pelvic radiation therapy has been compared with pelvic node resection in the setting of documented groin node–positive disease.

Evidence (pelvic node resection vs. pelvic radiation therapy):

  1. Patients with clinical stage I to stage IV primary squamous cell carcinoma of the vulva in whom groin node metastases were found at radical vulvectomy and bilateral groin lymph node dissection were randomly assigned (during the surgical procedure) to receive either ipsilateral pelvic node resection or pelvic radiation (45 Gy–50 Gy at 1.8 Gy–2.0 Gy per fraction).[ 16 ] Because of a perceived emerging benefit of radiation, the planned accrual of 152 patients was stopped after 114 patients were randomly assigned. However, the apparent benefit of radiation was subsequently attenuated with further follow-up.[ 16 ][Level of evidence: 1iiB]

Chemotherapy

There is no standard chemotherapy for vulvar cancer, and reports describing the use of this modality in the setting of metastatic or recurrent disease are anecdotal.[ 5 ]

Extrapolating from regimens used for anal or cervical squamous cell cancers, chemotherapy has been studied in combination with radiation in the neoadjuvant setting or as primary therapy in advanced disease. Chemotherapy regimens have included various combinations of fluorouracil (5-FU), cisplatin, mitomycin-C, or bleomycin.[ 5 ]

There is no clear evidence of improvement in survival or palliation. Given the advanced age and comorbidities of many patients with advanced or recurrent vulvar cancer, patient tolerance is a major consideration in the use of these agents.

Systemic treatment for inoperable patients

A systematic review of the use of neoadjuvant chemoradiation therapy in patients who were considered inoperable or who would have required extensive surgery, such as pelvic exenteration, colostomy, or urinary diversion, revealed no randomized trials.[ 17 ] Five nonrandomized studies that met the inclusion criteria of neoadjuvant chemoradiation therapy administered in this population with an intent to permit curative surgery were reviewed.[ 18 ][ 19 ][ 20 ][ 21 ][ 22 ] The five studies used four different chemoradiation therapy schedules and different radiation therapy dose-fractionation techniques. In the four studies using 5-FU with either cisplatin or mitomycin-C, the operability rate after chemoradiation therapy ranged from 63% to 92%.[ 18 ][ 19 ][ 20 ][ 21 ] In the one study using bleomycin, the operability rate was only 20%.[ 22 ]

In summary, there is evidence that neoadjuvant chemoradiation therapy with 5-FU plus either cisplatin or mitomycin-C may convert patients to a more operable status, but the evidence base is limited by study design. In addition to a paucity of randomized trials, interpretation of these studies is complicated by the lack of a standard definition of operability.[ 4 ][Level of evidence: 3iiiDiv] Treatment-related toxicity is substantial.

Systemic treatment for operable patients

There is limited evidence regarding the use of neoadjuvant chemoradiation therapy in advanced operable vulvar cancer, and the available data do not suggest an advantage to this approach. A systematic review found only one randomized trial that addressed this issue, and it was published only in abstract form.[ 4 ][ 23 ] In that trial, 68 patients with advanced vulvar cancer (T2* >4 cm, T3*, any case with positive lymph nodes) were randomly assigned to either receive preoperative neoadjuvant radiation therapy (50 Gy) concomitantly with 5-FU and mitomycin-C or primary surgery. Neoadjuvant therapy–related serious toxicity was high (13 of 24 patients; 10 patients had wound diastasis). After a mean follow-up of 42 months, the 5-year OS rate was 30% in the neoadjuvant chemoradiation therapy arm and 49% in the primary surgery arm (RRdeath, 1.39; 95% CI, 0.94–2.06; P = .19).[ 4 ][ 23 ][Level of evidence 1iiA] [Note: *T2 is defined as tumor confined to the vulva and/or perineum, more than 2 cm in greatest dimension, and T3 is defined as tumor that invades any of the following: the lower urethra, vagina, or anus.]

Vulvar Intraepithelial Neoplasia (VIN) Treatment

Standard Treatment Options for VIN

Standard treatment options for VIN include the following:

  1. Surgery.
  2. Topical imiquimod for patients who want to avoid surgery.[ 4 ][ 5 ][ 6 ][ 7 ][ 8 ]

Traditionally, there were three grades of VIN, however, there is little evidence that all three grades are part of the same biologic continuum or that grade 1 is even a cancer precursor. In 2004, the International Society for the Study of Vulvovaginal Disease (ISSVD) changed its terminology, reserving the designation VIN for two categories of lesions based on morphologic appearance.[ 9 ] In 2015, the ISSVD developed terminology for vulvar squamous intraepithelial lesions (SIL), which includes the following:[ 10 ]

High-grade VIN is usually managed with active therapy because of a higher risk for progression to invasive disease.[ 2 ] Estimates of progression rates are imprecise. A systematic literature review that included 88 untreated patients with VIN 3 reported a 9% progression rate (8 of 88 patients) to invasive vulvar cancer during 12 to 96 months of observation. In the same review, the spontaneous regression rate was 1.2%, all of which occurred in women younger than 35 years.[ 1 ] However, in a single-center study, 10 of 63 (16%) untreated women with VIN 2 or VIN 3 progressed to invasive cancer after a mean of 3.9 years.[ 11 ]

VIN lesions may be multifocal or confluent and extensive. It is important to perform multiple biopsies in treatment planning to exclude occult invasive disease. VIN located in nonhairy areas can be considered an epithelial disease; however, VIN found in hairy sites usually involves the pilosebaceous apparatus and requires a greater depth of excision because it can track along hair roots.

Surgery

The principal treatment approach is surgery, but there is no consensus on the optimal surgical procedure. The goal is to remove or destroy the entire VIN lesion while preserving vulvar anatomy and function. Simple vulvectomy yields a 5-year survival rate of nearly 100% but is seldom indicated. Other more-limited surgical procedures, including separate excision of multiple lesions, are less deforming.[ 12 ] The choice of treatment depends on the extent of the disease and the experience of the treating physician. There are no reliable data comparing the efficacy and safety of the various surgical approaches.

A systematic literature review identified only a single randomized trial comparing any of the surgical approaches.[ 2 ] In that trial, 30 women with high-grade VIN were randomly assigned to either receive CO2 laser ablation or ultrasound surgical aspiration.[ 3 ] There were no statistically significant differences in disease recurrence, painful dysuria or burning, adhesions, or eschar formation between the two treatments after 1 year of follow-up. Scarring was observed in 5 of 16 women treated with laser ablation and 0 of 14 women treated with ultrasound surgical aspiration (P < .01), but consequences of the scarring on sexual function or quality of life were not reported.[ 3 ][Level of evidence 1iiDii] The trial was too small to draw reliable conclusions about the relative efficacy of these surgical techniques. The remainder of the surgical literature is derived from case series and is prone to important study biases.[Level of evidence 3iiiD]

Whatever procedure is used, patients are at substantial risk of recurrence, particularly when the lesions are high grade or multifocal.[ 13 ] The most common sites of recurrence are the perianal skin, presacral area, and clitoral hood. About 4% of patients treated for VIN subsequently develop invasive cancer.[ 14 ][ 15 ]

Nonsurgical interventions

Topical imiquimod

Among women with high-grade VIN, substantial response rates and acceptable tolerability were reported for topical imiquimod 5%, an immune-response modifier with activity in human papillomavirus types 6- and 11-associated vulvar condylomata.

Evidence (imiquimod):

  1. Three randomized placebo-controlled trials (including a total of 104 patients) with clinical response as the primary endpoints have been reported in either peer-reviewed-journals or in abstract format.[ 7 ];[ 4 ][ 5 ][ 6 ][Level of evidence: 1iDiv] The results of these trials were summarized in a systematic review.[ 8 ]

Other nonsurgical interventions

Nonsurgical approaches have been studied because of the physical and psychosexual morbidity associated with many vulvar surgical procedures. Some of these approaches, including topical fluorouracil, recombinant interferon gamma, bleomycin, and trinitrochlorobenzene, have been largely abandoned because of high recurrence rates or intolerable local side effects, such as pain, irritation, and ulceration.[ 8 ][ 16 ]

Photodynamic therapy, using topically applied 5-aminolevulinic acid as the sensitizing agent for 635 nm laser light, has also been studied. However, data are limited to small case series with variable response rates.[ 17 ][ 18 ][Level of evidence: 3iiiDiv]

Stages I and II Vulvar Cancer Treatment

Standard Treatment Options for Stages I and II Vulvar Cancer

Standard treatment options for stage I and stage II vulvar cancer include the following:

  1. Surgery.
  2. Surgery and radiation therapy.
  3. Radiation therapy alone.

Surgery

Radical local excision with ipsilateral or bilateral inguinal and femoral lymph node dissection may be indicated. For stage I microinvasive lesions (<1 mm invasion) with no associated severe vulvar dystrophy, a wide (1 cm margin) excision (without lymph node dissection) may be done. For all other stage I lesions, if well lateralized, without diffuse severe dystrophy, and with clinically negative nodes, a radical local excision with complete unilateral lymphadenectomy may be done.[ 1 ] Candidates for this procedure should have lesions 2 cm or smaller in diameter with 5 mm or less invasion, no capillary-lymphatic space invasion, and clinically uninvolved nodes.[ 2 ] [ 3 ]

For stage II disease, large T2* tumors may require modified radical vulvectomy or radical vulvectomy.[ 4 ] [Note: *T2 is defined as tumor confined to the vulva and/or perineum, more than 2 cm in greatest dimension.]

For both stage I and stage II disease, radical local excision and sentinel node dissection is indicated and groin dissection is reserved for those with metastasis to the sentinel node(s).[ 5 ]

Surgery and radiation therapy

Some investigators recommend radical excision and groin nodal radiation therapy as a means to avoid the morbidity of lymph node dissection. However, it is not clear whether radiation therapy can achieve the same local control rates or survival rates as lymph node dissection in early-stage disease. A randomized trial to address this issue in patients with clinically localized vulvar disease was stopped early as a result of early emergence of worse outcomes in the radiation therapy arm.[ 6 ][ 7 ] For stage II disease, adjuvant local radiation therapy may be indicated for surgical margins smaller than 8 mm, capillary-lymphatic space invasion, and thickness greater than 5 mm.[ 8 ][ 9 ]

Radiation therapy alone

For patients unable to tolerate radical surgery or deemed unsuitable for surgery because of the site or extent of disease, radical radiation therapy may be associated with favorable survival.[ 10 ][ 11 ][ 12 ][ 13 ]

Stage III Vulvar Cancer Treatment

Standard Treatment Options for Stage III Vulvar Cancer

Standard treatment options for stage III vulvar cancer include the following:

  1. Surgery with or without radiation therapy.
  2. Radiation therapy or chemoradiation therapy followed by surgery.
  3. Radiation therapy with or without chemotherapy.

Surgery with or without radiation therapy

Modified radical or radical vulvectomy with inguinal and femoral lymphadenectomy is the standard therapy.[ 1 ] Nodal involvement is a key determinant of survival. Radiation therapy is given to patients with large primary lesions and narrow margins. Radiation therapy to the pelvis and groin is given if inguinal lymph nodes are positive.[ 2 ] Radiation therapy to the pelvis and groin is usually given if two or more groin nodes are involved.[ 2 ][ 3 ]

Localized adjuvant radiation therapy consisting of 45 Gy to 50 Gy may also be indicated when there is capillary-lymphatic space invasion and a thickness of greater than 5 mm, particularly if the nodes are involved.[ 1 ]

Radiation therapy or chemoradiation therapy followed by surgery

Preoperative neoadjuvant radiation therapy or chemoradiation therapy may be used to improve operability and even decrease the extent of surgery required.[ 4 ][ 5 ][ 6 ][ 7 ][ 8 ][ 9 ][ 10 ]

Radiation therapy with or without chemotherapy

For patients unable to tolerate radical surgery or deemed unsuitable for surgery because of the site or extent of disease, radical radiation therapy may be associated with long-term survival.[ 11 ][ 12 ] Some physicians prefer to add concurrent fluorouracil (5-FU) or 5-FU and cisplatin.[ 1 ][ 13 ]

Stage IVA Vulvar Cancer Treatment

Standard Treatment Options for Stage IVA Vulvar Cancer

Standard treatment options for stage IVA vulvar cancer include the following:

  1. Surgery.
  2. Surgery and radiation therapy.
  3. Radiation therapy or chemoradiation therapy followed by surgery.
  4. Radiation therapy with or without chemotherapy.

Surgery

Radical vulvectomy and pelvic exenteration may be indicated for patients with stage IVA vulvar cancer.

Surgery and radiation therapy

Surgery followed by radiation therapy may be done for large resected lesions with narrow margins. Localized adjuvant radiation therapy consisting of 45 Gy to 50 Gy may also be indicated when there is capillary-lymphatic space invasion and thickness greater than 5 mm.[ 1 ] Radiation therapy to the pelvis and groin is given if two or more groin lymph nodes are involved.[ 2 ][ 3 ]

Radiation therapy or chemoradiation therapy followed by surgery

Neoadjuvant radiation therapy or chemoradiation therapy of large primary lesions (to improve operability) may be done, followed by radical surgery.[ 4 ][ 5 ] [ 6 ][ 7 ][ 8 ][ 9 ][ 10 ]

Radiation therapy with or without chemotherapy

For patients unable to tolerate radical vulvectomy or who are deemed unsuitable for surgery because of the site or extent of disease, radical radiation therapy may be associated with long-term survival.[ 11 ][ 12 ] When radiation therapy is used for primary definitive treatment of vulvar cancer, some physicians prefer to add concurrent fluorouracil (5-FU) or 5-FU and cisplatin.[ 1 ][ 13 ][ 14 ][ 15 ][ 16 ][ 17 ]

Stage IVB Vulvar Cancer Treatment

Treatment Options for Stage IVB Vulvar Cancer

There is no standard treatment approach in the management of stage IVB vulvar cancer.

Local therapy must be individualized depending on the extent of local and metastatic disease.

There is no standard chemotherapy for metastatic disease, and reports describing the use of this modality are anecdotal.[ 1 ] However, by largely extrapolating from regimens used for anal or cervical cancer, chemotherapy has been studied. Regimens have included various combinations of fluorouracil, cisplatin, mitomycin-C, or bleomycin.[ 1 ][ 2 ][ 3 ] Given the advanced age and comorbidity of many patients with advanced or recurrent vulvar cancer, patient tolerance is a major consideration in the use of these agents.

Recurrent Vulvar Cancer Treatment

Treatment Options for Recurrent Vulvar Cancer

Treatment options for recurrent vulvar cancer include the following:

  1. Wide local excision with or without radiation therapy in patients with local recurrence.
  2. Radical vulvectomy and pelvic exenteration in patients with local recurrence.
  3. Synchronous radiation therapy and cytotoxic chemotherapy with or without surgery.[ 1 ]

Treatment and outcome depend on the site and extent of recurrence.[ 2 ] Radical excision of localized recurrence may be considered if technically feasible.[ 3 ] Palliative radiation therapy is used for some patients. Radiation therapy with or without chemotherapy may be associated with substantial disease-free periods in some patients with a small local recurrence.[ 1 ][ 4 ][ 5 ] When local recurrence occurs more than 2 years after primary treatment, a combination of radiation therapy and surgery may result in a 5-year survival rate of greater than 50%.[ 6 ][ 7 ]
