ObjectiveTo evaluate the impact of neoadjuvant chemoradiation on perineal wound healing following abdominoperineal resection(APR)for lower rectal cancer.MethodsData of 93patients who underwent APR for low rectal cancer between January 2005 and January 2009 in Peking Union Medical College Hospital were reviewed，including patients who received neoadjuvant chemoradiation(n=29)and those undergoing surgery alone(n=64).Perineal wound healing was the primary outcome measurement.Condition of wound healing was classified as good，moderate，and poor and was compared between the two groups.ResultsTwenty nine patients in the neoadjuvant group received preoperative regional radiation(50 Gy，25 fractions/5 weeks)with synchronous FOLFOX4chemotherapy(fluouracil and oxalipatin).In the neoadjuvant group，wound healing after APR was good in 18 patients(62.1%)，moderate in 6(20.7%)，and poor in 5(17.2%).In patients who had surgery alone，wound healing after APR was good in 41 patients(64.1%)，moderate in 15(23.4%)，and poor in 8(12.5%).There was no significant difference in the incidence of wound infection(poor wound healing)between the two groups(P=0.773).ConclusionNeoadjuvant chemoradiation therapy is not associated with increased perineal wound infection following abdominoperineal resection for low rectal cancer.13 refs，1 tab.
