Squamous cell carcinoma of the vulva is a rare disease, mainly seen in elderly women. Risk factors are advanced age, an immunocompromised status, longstanding vulvar dystrophy, VIN, a history of vulvar human papillomavirus infection, and a history of cervical cancer. Vulvar cancer should be considered as a skin tumor and detection is possible in an early stage. However, because of patients' and doctors' delay, one in three vulvar cancers is not treated before an advanced stage. The tumor metastasizes mainly lymphatogenic. Spread starts in the inguinal lymph nodes. In the middle of this century, standard treatment, consisting of an en bloc dissection of the vulva and inguinal lymph nodes has been developed and applied. As a result, considerably improved survival rates were achieved: up to 90% 5-year survival rates for patients without lymph node metastases. However, complication rates were high. In recent years, a more individualized approach has replaced standard treatment. Surgical treatment now depends on the localization, size and extent of the tumor, and is followed or preceded by radiotherapy in selected cases. The role of chemotherapy in advanced disease is currently being studied in several referral centers. The most important success in the treatment of vulvar cancer in recent years is the maintenance of high survival rates despite considerably less extensive surgical treatment, resulting in lower complications rates. An important challenge for the near future will be the improvement of the management of advanced disease. However, an even more difficult issue may be the prevention of such large lesions. The reduction of treatment delays requires a considerable effort in education of both health care workers and the general public.

The accuracy of high resolution ultrasound with guided fine needle aspiration cytology in detecting inguinal lymph node involvement was assessed in 24 women undergoing radical vulvectomy and groin node dissection for squamous cell vulval cancer. Of the 43 groins dissected, ultrasound correctly diagnosed the lymph node status in 36, with five false positive and two false negative results. Cytology in 40 groins showed no false positive and five false negative results. The sensitivity and specificity for the combined techniques were 83% and 82% respectively. Assessed together, the combined technique failed to detect metastatic disease in two groins; in both cases the extent of nodal metastatic involvement was a solitary focus < 3 mm in diameter. The ultrasound and fine needle aspiration procedure is safe and well tolerated and can be repeated as needed for surveillance. The authors suggest that this procedure should be evaluated further to determine whether a policy of individual selection for lymphadenectomy can be implemented based on this technique.

This study reviews our experience with 7 patients with primary Bartholin gland cancer (BGC) treated at the Queensland Gynaecological Cancer Centre (QCGC) and compares this with previously published data. A retrospective clinicopathologic review of all patients with primary BGC treated at QCGC from 1988 to 2000 was performed. Of the 7 patients treated, all underwent primary surgery and 5 of the 7 patients received radiotherapy postoperatively. All patients presented with a local swelling or a lump. Two had associated discharge and 2 had associated pain. Of the 7 patients, 2, 3 and 2 respectively were classified as having Stage IB, II or III disease. Five of the 7 patients had squamous cell carcinoma (SCC), one had adenoid-cystic carcinoma and 1 had a small-cell neuroendocrine cancer of the Bartholin gland. None of the patients with SCC developed recurrent disease. The patient with adenoid-cystic carcinoma experienced local recurrences at 4 years and again at 5 years and 3 months. Nine years after primary treatment she was diagnosed with pulmonary metastases. The patient with small-cell neuroendocrine cancer of the Bartholin gland was considered tumour-free after operation. Thorough imaging, including a CT scan of her chest, abdomen and pelvis showed no evidence of disease. She died 1 year and three months after diagnosis from disseminated pulmonary disease. We present the first report of small cell neuroendocrine cancer of the Bartholin gland. Therapeutic principles in the management of vulval cancer at other sites appear to be appropriate for management of BGC.

Vulvar cancer is a rare disease. Squamous-cell carcinomas account for 90% of vulvar cancers. The main mode of spread is lymphogenic to the inguinofemoral lymph nodes. Therefore, elective uni- or bilateral inguinofemoral lymphadenectomy is part of the standard treatment in combination with radical (wide) local excision of the vulvar tumour. Lymph drainage studies in relation to the biological behaviour of vulvar cancer are presented, as well as the anatomy and surgery of the groin. The sentinel lymph node procedure is a relatively new method of staging in vulvar cancer which may lead to the omission of inguinofemoral lymphadenectomy in those patients identified as not having inguinofemoral lymph node metastases. The accuracy of this technique appears to be high, but its safety still has to be proven. Moreover, the role of additional histopathological techniques for the examination of the sentinel lymph nodes needs to be established.

Radiotherapy may be used in the treatment of vulval cancer as an alternative to surgery in unfit patients, as an adjuvant to surgery in patients with poor prognosis tumours and for the treatment of inoperable, recurrent and metastatic disease. High-energy X-rays, electrons and both superficial mould and interstitial brachytherapy may be integrated in the regimen to produce the maximum tumour control and minimum morbidity. Concomitant chemoradiotherapy has a high response rate and may be used before surgery to reduce the morbidity of otherwise sphincter-sacrificing procedures. This chapter presents the historical development of radiotherapy for vulval cancer, the role of radiotherapy in the treatment of the primary tumour and also the loco-regional nodes, both for prophylaxis and for proven node metastasis. Techniques for delivering radiotherapy are then discussed and are followed by protocols detailing radiotherapy and chemotherapy doses for different clinical situations.

It is essential that any patient with resected vulval cancer and significant nodal disease receive optimal adjuvant treatment with radiation. Adequate radiotherapy for such patients with unilateral positive groin nodes has not been defined. Whether both groins and pelvic sidewalls should be irradiated or only the affected (node positive) side remains unclear. From our registry, we identified all patients with primary, previously untreated squamous cell carcinoma of the vulva undergoing bilateral inguinofemoral lymphadenectomy (superficial and deep nodes) and having unilaterally positive groin nodes treated with unilateral groin and pelvic radiotherapy (44 Gy in 22 fractions). Clinical and pathologic records were reviewed to identify the anatomical site and timing of recurrences in these patients and determine whether unilateral groin and pelvic irradiation was sufficient for disease control on the node-negative side. From 1983 to 2002, 20 patients with unilateral positive nodes treated with unilateral groin and pelvic irradiation were identified. Nineteen patients were classed as having FIGO stage III disease and one as FIGO stage IV due to involvement of the rectal mucosa. There were nine patients with disease recurrences in this group (45%). The disease-free interval ranged from 4 to 31 months (median time to recurrence, 9 months). All nine patients had local or regional failures, the most common site being the ipsilateral groin (six of nine patients). One patient was also found to have distant metastases. There were no recurrences noted in the contralateral (nonirradiated) groin or pelvic sidewall. Recurrence was generally fatal. Eight of the nine patients subsequently died of their disease. The ninth patient died of another cause. There was a high incidence of regional failure after unilateral groin and pelvic radiotherapy, but there were no recurrences on the nonirradiated, node-negative side. Although a small series, we speculate that there is no apparent disadvantage to administering unilateral adjuvant radiotherapy for unilaterally positive groin nodes and encourage further studies in order to more confidently determine whether the tendency observed in our center holds true.

Vulvar cancer is an uncommon but devastating disease. In addition to radical vulvectomy, most patients require inguinofemoral lymphadenectomy, which often results in wound infection, wound breakdown, and chronic lymphedema. In the past, the gold standard for early lesions was radical vulvectomy with complete bilateral inguinal-femoral lymphadenectomy. This resulted in a low rate of recurrence but devastating disfigurement and high complication rates. Because only approximately 20% of patients with vulvar cancer have positive lymph nodes upon presentation, the traditional approach of inguinal-femoral lymphadenectomy for all patients resulted in many patients undergoing a morbid procedure without any real benefit. Sentinel node dissection, by removing only the nodes with the highest risk of containing metastases, offers a much less morbid alternative. In addition, because only one or two lymph nodes are removed, these can be subjected to a more thorough histopathologic analysis than conventional complete lymphadenectomy. This involves serial sectioning and immunohistochemical staining for cytokeratin antigen. Very small metastases, termed micrometastases, can be detected in this fashion. Therefore, sentinel node dissection with serial sectioning and immunohistochemical staining potentially offers a more accurate assessment of the regional nodes with less morbidity. Patients with positive sentinel nodes may then undergo additional therapy. Patients with negative sentinel nodes are theoretically at very low risk for metastases and should not require any additional treatment.

The sentinel lymph node (SLN) procedure is used in our institute in the setting of an observational multicenter study investigating the reliability of the sentinel node procedure in vulvar carcinoma (GROINSS-V: The Groningen International Study on Sentinel Nodes in Vulvar Cancer). One of our patients had a groin recurrence where the SLN had been reported as negative. After reviewing this SLN, it contained several anucleate, keratin-positive structures on immunohistochemistry, and in the same area on hematoxylin and eosin coloring, one single cell with a nucleus interpreted as a tumor cell. Our objective was to assess how frequently these anucleate structures occur and whether such nodes should be regarded as positive. The sentinel nodes from 32 patients with early-stage vulvar squamous cell carcinoma were reviewed. Seventy-seven SLN's were identified. In ten patients, the SLN was positive and a bilateral inguinofemoral lymph node dissection was subsequently performed. In two of these ten patients, both with a macrometastasis on SLN, further metastatic disease was present in the dissection specimen. Anucleate keratin-positive structures were seen on immunohistochemistry in 14 SLN's (18%), usually along with metastasis or single tumor cells, but in five nodes this was the only abnormality (mean follow-up period of 26.28 months). Anucleate keratin-positive structures are a common finding in immunohistochemical examination of SLN's. Our findings suggest that they are of no clinical significance and the SLN should be regarded as negative. When an atypical cell with a nucleus is present, the SLN should be classified as positive and further management should be accordingly.

1. Vulvar cancer is surgically staged. 2. Imaging such as CT of the abdomen and pelvis should be performed for women with tumors 2 cm or larger or to detect lymph node or other metastases. 3. Staging should include evaluation of factors related to prognosis: tumor size, depth of invasion, lymph node involvement, and presence of distant metastases. 4. Inguinofemoral lymph node metastasis is the most important predictor of overall prognosis. 5. Inguinofemoral lymphadenectomy or sentinel lymph node evaluation can be omitted for lesions 2 cm or smaller and depth of invasion less than 1 mm. 6. Sentinel node biopsy seems to be a reliable means to pathologically assess inguinofemoral lymph node metastasis. 7. All tumors larger than 2 cm require pathologic inguinofemoral lymph node evaluation. 8. Radical local excision or modified radical vulvectomy is appropriate for most stage I and II lesions located on the lateral or posterior aspects of the vulva. 9. A tumor-free surgical margin of at least 1 cm decreases the risk of local recurrence. 10. Chemoradiation therapy is the preferred approach for most patients with very advanced vulvar cancer.

Vulvar cancer (VC) is a rare disease, usually diagnosed in a stage still amenable to potentially curative treatments, including surgery and/or radiation therapy with or without chemotherapy. Several patients however present at diagnosis with metastatic disease and another 30-50% will relapse. Prognosis of metastatic or recurrent disease not amenable to salvage surgery or radiotherapy is very poor. Evidence about the efficacy of chemotherapy in this setting is limited and its role still remains unclear. At present there is no standard treatment for advanced VC and patients are usually treated with schedules adopted for chemoradiation or extrapolated from cervical cancer. We report our experience using a cisplatin-gemcitabine regimen in two cases of metastatic squamous cell VC. No response was obtained with this schedule. No other data are available in the literature about the choice of a cisplatin-gemcitabine regimen in this patient subset. The paucity of evidence about the role of palliative chemotherapy in metastatic VC justifies any effort to implement knowledge. For this reason we think it is notable to also report a negative experience. It is not possible for us to conclude that this chemotherapy would be unable to provide any benefit in a larger sample of patients; nonetheless we think that new agents, rather than combinations of older drugs, could hopefully provide more benefit.
