Objective To evaluate the efficacy of trolamine cream in the prevention and treatment of acute radioactive dermatitis in patients with breast cancer after modified radical mastectomy.Methods 80 breast cancer patients who received postmastectomy chest-wall irradiation by 6-MeV electron beam were included.40 cases in the treatment group were given trolamine cream combined with the conventional nursing care during radiotherapy,while another 40 cases in the control group were treated with the conventional nursing care.Results In the treatment group,the rates of radiation dermatitis of grade 1,2 and 3 were 70.0 ％ (28/40),22.5 ％(9/40),and 7.5 ％ (3/40),respectively,while they were 52.5 ％ (21/40),32.5 ％ (13/40) and 15.0 ％ (6/40),respectively,in control group (P ＜ 0.05).Grade 1,2 and 3 radiation dermatitis appeared in treatment group when the radiation doses were (21.91±4.39) Gy,(37.43±6.50) Gy and (46.14±6.50)Gy,respectively,while in the control group,it was (12.67±2.16) Gy,(22.61±3.51) Gy,(42.71±8.11) Gy (P ＜ 0.05),respectively.With cumulative doses of 10 Gy and 25 Gy,the rates of radiation dermatitis in the treatment group were 22.5 ％ (9/40) and 47.5 ％ (19/40),respectively,while they were 40.0 ％ (16/40) and 62.5 ％ (25/40),respectively,in the control group (P ＜ 0.05).Conclusions Trolamine cream effectively alleviates radiation skin damage in breast cancer patients after modified mastectomy,thus it is suitable for use in patients with postoperative chest wall radiotherapy.
