目的探讨乳腺癌术后放射治疗及食管癌根治性放射治疗在锁骨上区照射范围的差异。方法回顾性分析2003年5月至2013年4月间广东省中山市人民医院收治的127例食管癌患者及115例乳腺癌患者锁骨上淋巴结转移情况,测量CT轴位图像上转移淋巴结的相对位置。结果两组患者在淋巴结转移数目、高于环状软骨的转移数目和转移途径分区上的分布差异无统计学意义(P>0.05)。食管癌患者转移淋巴结中心至体中线的距离(转移距离)为(1.76±1.21)cm,范围0~5.20 cm,95%CI的上限为5.01 cm,乳腺癌患者转移淋巴结的转移距离、范围和95%CI上限依次为(1.49±0.98)cm、0~4.60 cm和4.39 cm,两者差异无统计学意义(P>0.05)。结论食管癌根治性放射治疗和乳腺癌术后放射治疗的锁骨上淋巴结区域CTV勾画范围近似,需包括所有解剖引流区,外界均以离体中线不超过6 cm为宜。
Objective To investigate the difference in the irradiation range of supraclavicular area after radiotherapy for breast cancer and radical radiotherapy for esophageal cancer. Methods The clinical data of 127 patients with esophageal cancer and 115 patients with breast cancer who were treated in Zhongshan People’s Hospital of Guangdong Province from May 2003 to April 2013 were retrospectively analyzed. The relative position of metastatic lymph nodes on CT axial images was measured . Results There was no significant difference in the number of lymph node metastasis, the number of metastasis of annular cartilage and the distribution of metastasis in both groups (P> 0.05). (1.76 ± 1.21) cm, ranged from 0 to 5.20 cm, and the upper limit of 95% CI was 5.01 cm in esophageal cancer patients. The distance and range of metastatic lymph node metastasis in breast cancer patients The upper limit of% CI was (1.49 ± 0.98) cm, 0 ~ 4.60 cm and 4.39 cm, respectively, with no significant difference (P> 0.05). Conclusions The scope of CTV mapping of supraclavicular lymph nodes in patients with esophageal carcinoma radical radiotherapy and postoperative radiotherapy of breast cancer should include all anatomic and drainage areas, and the outside world should be less than 6 cm off centerline.
