ABSTRACT
PURPOSE: The objective of this study was to assess survival and prognostic factors for anal carcinoma in the population. METHODS: Patients with squamous-cell canal were identified from National Cancer Data Base (1985-2000). Univariate multivariable methods used associated survival. Concordance calculated agreement between American Joint Committee on stage actual outcome. RESULTS: Nineteen thousand one hundred ninety-nine patients (Stage I, 25.3 percent; Stage II, 51.8 III, 17.1 IV, 5.7 percent). Overall five-year 58.0 percent. (6th edition) staging system provided good discrimination by stage: 69.5 59.0 40.6 18.7 percent (concordance index, 0.663). On analysis, had a higher risk death if they male, ≥65 years old, black, living lower median incomes areas, more advanced T tumors, nodal or distant metastases, poorly differentiated cancers (P < 0.0001). There not significant difference hospital type year diagnosis. CONCLUSION: Although tumor characteristics affect prognosis, patient factors, such as gender, race, socioeconomic status, are also important canal.
