Stratification of anorectal melanoma patients according to clinical stage at presentation. a Classification of patients using a modified Ballantyne clinical staging system. The patients were classified initially according to anatomic sites of involvement as having localized disease, regional metastases, or distant metastases. Patients with localized disease and regional disease were further subdivided on the basis of nodal status. b Kaplan–Meier estimates of disease-specific survival (DSS) based on clinical stage at presentation
