ABSTRACT
Objective To investigate the diagnosis and treatment of anorectal malignant melanoma,in order to regulate surgical methods and explore multi-modality treatment.Methods Clinical pathological features,diagnosis and treatment procedures of 38 patients with anorectal melanoma were reviewed,and their correlation with prognosis were analyzed.Results In 38 patients,10 of them were male and 28 were female,with the mean age of 58.7 years old (ranged 28-75 years old).28 patients underwent abdominoperineal resection,10 patients underwent wide local excision.The 1-,3-,and 5-year disease-free survival rates were 64.9 %,18.5 % and 5.7 %,respectively.The 1-,3-,and 5-year overall survival rates were 85.8 %,24.1% and 6.4 %,respectively.Tumor thickness (≥ 1.51 rm) and tumor diameter (≥3 cm) were associated with lymph metastases (x2 =13.093,4.449,P =0.011,0.020),tumor thickness was also associated with distant metastases (x2 =11.965,P =0.018).According to the Kaplan-Meier method,comprehensive treatment after surgery had significant effects on disease-free survival (x2 =7.441,P =0.006).Tumor thickness,lymph metastases,and clinical staging had significant effects on overall survival (x2 =16.741,16.474,16.775,P =0.002,0.000,0.000).Cox proportional hazards model indicated that comprehensive treatment after surgery was the independent prognostic risk factors of disease-free survival (95 % CI 1.420-17.621,P =0.012).Tumor thickness and lymph metastases were the independent prognostic risk factors of overall survival (95 % CI 0.250-0.949,1.033-2.573,P =0.035,0.036).Conclusion Early detection,reasonable surgical procedure,generalized systemic focus on immunotherapy treatment are the key to improve quality of life and prolong the survival time of anorectal malignant melanoma patients.
