本文报告贲门癌、食管下段癌待手术患者,左锁骨上扪不到淋巴结的100例,行左锁骨上前斜角肌脂肪垫整块切除后病理检查结果,阳性率为5％。对病期长短、病变长度及临床病理分期与阳性率无明显关系、切除之淋巴结大小亦与是否阳性无关。作者认为待手术的贲门癌、食管下段癌患者如能先作左锁骨上活检,可避免无意义的手术。 This article reports patients with cardiac cancer, lower esophageal cancer to be treated, 100 cases of left clavicle up to the nodal lymph nodes, the left clavicle of the anterior scalene muscle fat pad whole block after removal of the pathological examination results, the positive rate was 5%. There was no significant relationship between the length of the disease, the length of the lesion and the clinical pathological stage and the positive rate. The size of the resected lymph node was not related to whether it was positive or not. The author believes that if patients with cardiac cancer or lower esophageal cancer undergo surgery, they can first perform a left supraclavicular biopsy to avoid meaningless surgery.
