Surgical management of epidermoid carcinoma of the anus.
An analysis of twenty-six cases of epidermoid carcinoma of the anus from the University of Virginia Medical Center and 1,060 cases from the surgical literature has been presented. We believe this review justifies the following conclusions. (1) Considerable delay in diagnosis frequently occurs, adversely affecting the prognosis of patients with this disease. (2) Abdominoperineal resection remains the treatment of choice. Wide local excision is inadequate for most lesions, and should be reserved for lesions of the anal verge less than 2 cm in diameter with favorable histology, that is, low grade of malignancy. (3) Large lesions and those with a high grade of malignancy are associated with a poor prognosis, but even these patients may sometimes be cured with aggressive surgical excision. (4) Synchronous inguinal node metastases are associated with a poor prognosis, but an occasional patient may be cured by iliofemoral node dissection. (5) Iliofemoral node dissection is indicated for metachronous inguinal node metastases in the absence of distant spread. (6) Iliofemoral node dissection should not be performed if these nodes are not clinically involved with metastases. Approximately 70 per cent of these patients will not need this procedure and would therefore have this resection and its attendant morbidity unnecessarily.
