ABSTRACT
<p><b>OBJECTIVE</b>To explore the prognostic factors of anorectal malignant melanoma (ARMM).</p><p><b>METHODS</b>Medical records and follow-up data of 34 patients with ARMM treated in the Chinese PLA General Hospital from March 1993 to November 2011 were analyzed retrospectively.</p><p><b>RESULTS</b>There were 26 abdominoperineal resections(APR) and 8 wide local excisions (WLE). Twenty patients underwent postoperative adjuvant therapy, including chemotherapy in 14 cases, radiotherapy in 2 cases, traditional Chinese medicine therapy in 4 cases and immunotherapy in 16 cases. Postoperative follow-up was carried out in all the patients and the mean follow-up period was 27 months. The 1-, 3- and 5-year overall survival rates were 76.3%, 39.6% and 20.6% respectively, while the 1-, 3- and 5-year disease-free survival rates were 60.6%, 30.8% and 12.8% respectively. APR and postoperative immunotherapy could significantly reduce the local recurrence rate. According to the Kaplan-Meier method, gross type of tumor, mural involvement, lymph metastasis, and clinical staging had significant effects on overall survival, while lymph metastasis and postoperative immunotherapy on disease-free survival. Cox proportional hazards model indicated that the clinical staging and postoperative immunotherapy were significant predictive factors.</p><p><b>CONCLUSIONS</b>Early diagnosis and correct choice of surgical method are the keys to the treatment. Postoperative immunotherapy can prolong disease-free survival.</p>
