Anal canal carcinoma

Patients with anal cancer often delay seeking medical care. In addition, anal cancer is often misdiagnosed, or the diagnosis is significantly delayed, during which time the patient receives treatment for other benign anorectal disease eg, hemorrhoids. Some authors suggest that endoanal ultrasound can accurately determine the depth of penetration of the carcinoma into the sphincter complex and can be used to accurately gauge the response of these tumours to chemoradiation therapy 8. A combined modality of treatment for patients with anal cancer can cause morbidity due to its potential for treatment interruptions owing to gastrointestinal and dermatologic toxicities.

In a study from France in patients treated mostly with radiotherapy alone, response to radiotherapy was significantly associated with disease-free survival, both on univariate and multivariate analysis. Eleven patients received 5-FU plus cisplatin, one received 5-FU plus mitomycin, one patient was offered wide local excision, and one declined therapy.
