俯卧位碳纤维腹板加热塑膜固定技术在直肠癌放疗中的临床应用
The clinical application of prone position of carbon fiber web heating plastic film fixation technique in radiotherapy for rectal cancer
摘要
Abstract
Objective To study the prone position of carbon fiber web heating plastic film fixation technique on radiotherapy posture of rectal cancer, and its protection on the organs at risk.Methods A total of 50 postoperative patients with rectal cancer were randomly divided into two groups, with 25 cases in each group.The observation group underwent prone carbon fiber web heating plastic film fixed Intensity-modulated radiation therapy (IMRT), while the control group was treated with supine thermoplastic film and special plate fixation IMRT.The mean dose (Dmean) and total volume (VT) of the planned target area (PTV), the small bowel and bladder irradiation dose and volume were compared between two groups;the setup errors and incidence of acute radioactive reaction were compared between two groups.Results There were no significant difference of Dmean and VT in PTV between the two groups(P>0.05);the Dmean and irradiation volume in the small bowel and bladder of the observation group were significantly lower than those in the control group (P<0.05).There were no significant difference of displacement error of head-foot, left-right, and front-back between the two groups (P>0.05).The severity of gastrointestinal reactions and urinary tract reactions in the observation group was significantly lighter than those of the control group during the treatment period and after treatment (P<0.05).Conclusions The prone position of carbon fiber web heating plastic film fixation technique used in radiotherapy after radical resection of rectal cancer can ensure the efficacy of radiotherapy, protect the small intestine and bladder, and has good position repeatability and high safety.关键词
