Objective To assess the effectiveness and characteristics of intratumoral radioactive seed im-plantation in low rectal cancer with anal sphincter preservation.Methods Clinical data of 8 patients(not willing or can not to undergo radical resection of rectal carcinoma)with low rectal cancer receiving radioactive seed implan-tation with anal sphincter preservation were retrospectively analyzed.Results All the 8 patients successfully com-pleted intratumoral radioactive seed implantation.Preoperative clinical symptoms of discomfort were significantly improved,and CEA levels decreased significantly.Colonoscopy and CT examination showed that tumor disap-peared in 4 cases,anal function was successfully preserved in all patients.The mean survival time was 32.4 months.Conclusions Intratumoral radioactive seed implantation in low rectal cancer with anal sphincter preser-vation can effectively improve the quality of life of patients.
