Abstract:
Objective To evaluate the influence of rectal washout on the prognosis of rectal cancer after anterior resection.Methods Data of 144 patients with rectal cancer undergoing anterior resection at Chinese Academy of Medical Science Cancer Hospital between May 2006 and November 2007 were reviewed.69 patients received rectal washout and 75 patients did not.The incidences of recurrence and 5-year disease-free survival rates were compared.Data were analyzed by SPSS 13.0 software packet,using x2 and t inspection.Kaplan-Meier method was used to calculate postoperative survival rate.Results Washing sample was positive for malignant cells in 55 patients (79.7％).The incidences of recurrence were 4.6％ and 6.7％ in washout group and no-washout group respectively (x2 =0.368,P =0.721).The five-year disease-free survival rate was 79.7％ in washout group and 74.7％ in no-washout group(x2 =0.517,P =0.553).Conclusions Free malignant cells were ubiquitous in rectal lumen during anterior resection,and there was a high positive rate of cytological examine for washout sample.Rectal washout may reduce local recurrence and prolong patients' survival.
