通常认为外科手术是非小细胞肺癌(NSCLC)患者的首选治疗方法,而对于有严重肺或心血管疾患的患者,放疗可成为一种有效的替代选择疗法,本研究探讨对T_(1～2)N_0的NSCLC患者能否不做选择性淋巴结区放疗仅采用局部野放疗。 对1988～1993年的T_(1～2)N_0NSCLC患者31例实行根治性放疗,采用前后对穿野照射48Gy,前40Gy临床靶区包括肿瘤边缘至少1.5cm,然后缩野至肿瘤边缘o.5cm加量,放射野不包括肺门与纵隔,均用6～15MVX线加速器。31例患者中2例为拒绝手术,2例为双原发肿瘤,27例为心肺疾患。均有胸部CT评价淋巴结状
Surgical procedures are generally considered to be the first choice for patients with non-small cell lung cancer (NSCLC). However, radiotherapy may be an effective alternative treatment for patients with severe pulmonary or cardiovascular disease. This study investigated T_(1~2). Whether or not N_0 patients with NSCLC can only perform local radiotherapy without selective lymph node radiotherapy. Thirty-one patients with T_(1~2)N_0NSCLC from 1988 to 1993 underwent curative radiotherapy. Before and after the application, 48 Gy was applied to the field. The first 40 Gy clinical target area including the edge of the tumor was at least 1.5 cm, and then the tumor was constricted to the edge of the tumor. Addition, radiation field does not include the hilar and mediastinum, both with 6 ~ 15MVX line accelerator. Among the 31 patients, 2 were refused surgery, 2 were primary tumors, and 27 were heart and lung diseases. There are chest CT evaluation of lymph nodes
