Radical vulvectomy for squamous cell carcinoma of the vulva

Surgical interventions for early squamous cell carcinoma of the vulva

BACKGROUND

Radical surgery has been standard treatment for patients with early vulvar cancer since mid century. Survival figures are excellent, but complication rates are high. Over the last two decades, surgical treatment has become more individualised in order to decrease complications in patients with limited disease.

OBJECTIVES

To determine whether the effectiveness and safety of individualised treatment is comparable with that of more extensive (non-individualised) surgery.

SEARCH STRATEGY

The cirteria set by the Cochrane Gynaecological Cancer Group were used. We searched Medline and Embase (last search on 16 November 1999) We used our own publication archives, based on a prospective handsearch of six leading relevant journalswhich was started in December 1986. Reference lists of identified studies, gynaecological cancer handbooks and conference abstracts were also used.

SELECTION CRITERIA

Types of study: RCT's, case control and observational studies on the effectiveness of surgical treatment of vulvar cancer.

TYPES OF PARTICIPANTS

patients with cT1N0M0 squamous cell carcinoma of the vulva. Types of interventions: local surgical treatment as well as regional lymph node dissection. Types of outcome measurements: overall, disease specific and disease free survival; treatment complications; quality of life issues.

DATA COLLECTION AND ANALYSIS

The two reviewers independently assessed study quality and extracted data.

MAIN RESULTS

Only two studies with a total of 94 participants were included in the review. Both were observational studies. None of the other eleven considered studies met the minimum criteria as set by the Cochrane Collaboration. From these two studies, it can be concluded that: 1. radical local excision is as safe as a radical vulvectomy; 2. An ipsilateral lymph node dissection is safe in patients with a well lateralised tumour, and 3. A superficial groin node dissection is not as safe as a full femoro-inguinal groin node dissection. The fourth question we intended to answer is of great clinical importance: is the triple incision technique as safe as an en bloc dissection? This question could only be answered by using some of the unselected studies. From these studies, the triple incision technique appears to be as safe as the en bloc technique.

REVIEWER'S CONCLUSIONS

The available evidence regarding surgical treatment of early vulvar cancer is generally of poor quality. From the evidence with sufficient quality we conclude that radical local excision, ipsilateral lymph node dissection in lateral tumors and triple incision technique are safe treatment options for early vulvar cancer. However, superficial groin node dissection results in an excess of groin recurrences compared to a full femoro-inguinal groin node dissection.

Vulvar squamous cell carcinoma metastatic to the skin

BACKGROUND

Cutaneous metastases from vulvar squamous cell carcinomas (SCC) have been reported only twice previously and both patients expired shortly after they occurred. Mohs surgery has been reported in three previous publications as a successful treatment for local invasive vulvar SCC and Bowen's disease.

OBJECTIVE

To describe a third case with cutaneous metastases and 14 other cases of invasive and in situ vulvar SCC treated by fresh tissue Mohs surgery in a pilot study at the University of Wisconsin between 1976 and 1995.

METHODS

We took photographs of the gross appearance and of the histologic slides of the tumor at the local site and at the metastatic sites on the skin and reviewed patients' charts.

RESULTS

One patient developed pelvic and cutaneous metastases 5 years after radical vulvectomy with bilateral node dissection. She expired shortly after the skin metastases appeared. The courses of the patients followed after Mohs surgery for vulvar SCC were variable.

CONCLUSIONS

Cutaneous metastases from vulvar SCC are rare but carry a grim prognosis. Mohs surgery should be considered in select cases to try to prevent excess morbidity and mortality.

Risk factors for groin node metastasis in squamous carcinoma of the vulva: a multivariate analysis of 39 cases

This study includes 39 patients with squamous carcinoma of the vulva subjected to radical surgery. Stage, tumor description, cell type, lesion localization, lesion size, depth of invasion, grade, lymphovascular space invasion, number of mitoses, degree of stromal inflammatory reaction, and tumors in surgical margins were analyzed for groin metastasis. Of the factors analyzed, stage (P = 0.018), grade (P = 0.007) and depth of invasion (P = 0.001) were found to be the most important predictors of node metastasis. While a combination of factors permitted to define a low-risk group with 0% node metastasis, it seems hard to identify preoperatively those patients with no risk of nodal metastasis.
