Fatores prognósticos e sobrevida no adenocarcinoma primário de reto
2008
The objective of this study was to evaluate survival and clinicopathological factors in rectal adenocarcinoma, the records of 112 patients were reviewed for: age, gender, serum level of CEA, surgery curability, follow-up, recurrence, survival and tumor histopathology. Kaplan-Meyer curves were used to analyze survival. Statistical significance in bivariate and stratified analysis was set at P N1, P<0.001) and recurrence (P<0.001). Independent prognostic factors were Dukes stages and tumor grade (P=0.089), as well as depth of invasion and lymph node involvement when Dukes staging was excluded (P=0.091 and <0.001). Besides tumor grade, the prognostic factors identified meet classification levels in current staging systems.
