The Influence of Histopathologic Criteria on the Long-Term Prognosis of Locally Excised pT1 Rectal Carcinomas: Results of Local Excision (Transanal Endoscopic Microsurgery) and Immediate Reoperation

Abstract

Local R0-resection in cases with low-risk pT1 carcinomas represents an oncologically adequate therapy, which results in similar survival rates compared with primary radical surgery of pT1N0M0 rectal carcinomas. High recurrence rates are observed in tumors with unfavorable histologic result (Group B) requiring further treatment. In these cases immediate reoperation reduces the recurrence rate to 6 percent.
