Abstract:
Objective To investigate the relative analysis of prognostic factors in primary anorectal malignant melanoma (AMM). Method Twenty-seven patients with AMM were treated, Log-rank and COX analysis were used to find out the relationship of ten factors to survival. Results Log-rank analysis found five of ten factors affecting survival, they were age of patient,diameter of tumor, infiltrated depth,pathological staging and metastasis (P<0.05 or<0.01), while COX analysis only found the diameter of tumor and infiltrated depth had close relationship to survival (P<0.05 or<0.01). Conclusion The diameter of tumor and infiltrated depth are the main factors affecting the survival of AMM, and this indicates the importance of early diagnosis and treatment.
