目的 评价立体定向适形放疗的近期疗效。方法 对 16 3例手术病理或活检确诊的肿瘤进行治疗计划和优化 ,根据治疗计划使射线对肿瘤实施共面或非共面多野集中照射。结果 除 4例晚期食道癌、 1例贲门癌外 ,余 15 8例恶性肿瘤治疗后 ,CT复查肿瘤缩小 >1/ 2 ;4 8例食道癌及 15例贲门癌治疗后 ,食道钡餐点片与治疗前 X光片对比明显好转 ,进食梗阻感消失 ,食量基本恢复正常 ,有胸背痛者则疼痛消失 ;原发性肝癌患者血 AFP明显下降 ,疼痛患者治疗后疼痛完全缓解。治疗后急性毒副反应轻微 ,全部病例治疗前后白细胞计数无明显变化 ;4 0例肝肿瘤治疗前后无明显肝功能损害。结论 立体定向适形放疗是一种治疗恶性肿瘤安全、可靠、有效的方法。
Objective To evaluate the short-term effect of stereotactic conformal radiotherapy. Methods Totally 16 3 patients with pathologically confirmed or biopsy-confirmed tumors were treated and optimized. According to the treatment plan, the radiographs were focused on the tumors by coplanar or non-coplanar multi-field irradiation. Results In addition to 4 cases of advanced esophageal cancer and 1 case of cardia cancer, more than 15 cases of malignant tumors after treatment, CT review of tumor shrinkage> 1/2; 48 cases of esophageal cancer and 15 cases of cardia cancer treatment, barium meal tablets and Before treatment, the contrast of X-ray film was obviously improved, the obstruction of feeding obstruction disappeared, the appetite returned to normal, and those with thoracic and back pain disappeared. The blood AFP of patients with primary liver cancer was significantly decreased, and pain was relieved completely after treatment. Acute adverse reactions were mild after treatment, before and after treatment in all cases no significant change in white blood cell count; 40 cases of liver cancer before and after treatment no significant liver damage. Conclusion Stereotactic conformal radiotherapy is a safe, reliable and effective method for the treatment of malignant tumors.
