摘要:
目的:探讨伽玛刀治疗肺癌脑转移瘤的临床疗效及不良反应。方法:选择伽玛刀治疗肺癌脑转移瘤患者236 例,根据病变大小和部位选用4-18mm 准直器靶点,肿瘤边缘剂量12-22Gy,平均17Gy,中心剂量32-40Gy,平均35.4Gy,边缘等剂量曲线40%-75%,平均58%。 结果:对全部患者伽玛刀治疗后进行临床随访,视具体情况1-3 个月复查影像,随访时限不少于半年;6个月、12个月患者生存率,腺癌患者分别为69.1%(56/81)、38.3%(31/81),鳞癌患者为60.0%(45/75)、20.0%(15/75),小细胞癌患者则为62.7%(37/59)、27.1%(16/59);伽玛刀治疗后1-3个月随访KPS评分,提高128 例(54.2%),不变81 例(34.3%),下降27例(11.4%)。腺癌、鳞癌、小细胞癌、鳞腺混合癌脑转移瘤局部控制有效率分别为87.7%(71/81)、93.3%(70/75)、100%(59/59)、85.7%(18/21)。无1例患者出现严重脑水肿而终止放疗,无1例患者出现严重骨髓功能抑制。 结论:伽玛刀治疗肺癌脑转移瘤具有疗效好、安全的优势,能有效提高脑转移瘤患者生活质量,延长生存期。
Abstract:
Objective:To investigate the clinical efficacy and adverse reactions of gamma knife radiosurgery for brain metastases of lung cancer.Methods:All 236 cases of metastasis tumor in patients with lung cancer with brain were treated with gamma knife,selection of 4-18mm collimator target according to lesion size and position,the tumor margin dose of 12-22Gy,average 17Gy,central dose of 32-40Gy,average 35.4Gy,edge isodose curve 40%-75%,with an average of 58%.Results:The follow-up for all patients after treatment was not less than half a year.6 months,12 months survival rates were 69.1%(56/81),38.3%(31/81),squamous cell carcinoma was 60%(45/75),20%(15/75),small cell carcinoma was 62.7%(37/59),27.1%(16/59);Gamma knife treatment after 1-3 months of follow-up KPS score,128 cases were improved (54.2%),remained unchanged in 81 cases (34.3%),decreased by 27 (11.4%).The local control rates were 87.7% in adenocarcinoma,squamous cell carcinoma,small cell carcinoma,adenosquamous mixed cancer brain metastasis 87.7%(71/81),93.3%(70/75),100%(59/59),85.7%(18/21).There were no cases of severe cerebral edema no cases of severe bone marrow suppression.Conclusion:Gamma knife radiosurgery for brain metastases of lung cancer has good efficacy,safe,can effectively improve the quality of life of patients with brain metastatic tumor,prolong the survival period.
