作者们对162例喉癌患者在原发灶治愈后区域性淋巴结转移发生频率进行了研究。这些病例事先均未确定有颈淋巴结转移。其中Ⅲa期者101例,Ⅳa期者52例,放疗后复发者9例。有68例患者仅对其原发病灶进行了根治性治疗,结果发生区域性淋巴结转移者占42.6%。另外有94例类似期的患者其原发灶进行了相同方法的治疗,随后又对病变侧的颈部进行了预防性淋巴组织切除(51例),或按照根治量对转移区域进行了预防性放射治疗(43例)。此二组病人随机分组。受到预防性手术者发生转移的占5.8%,而放疗组为13.9%。平均在预防治疗后区域淋巴结转移发
The authors studied the frequency of regional lymph node metastases in 162 patients with laryngeal cancer after the primary lesions were cured. None of these cases had a prior determination of cervical lymph node metastases. Of which 101 cases of stage Ⅲ a, Ⅳ a period of 52 cases, 9 cases of recurrence after radiotherapy. 68 patients only radical treatment of their primary lesions, the results of regional lymph node metastasis accounted for 42.6%. In addition, 94 patients with similar stage had their primary tumors treated in the same way, followed by prophylactic lymphoid resection (51 cases) on the lesion side of the neck or prophylactic Radiation therapy (43 cases). The two groups of patients were randomized. 5.8% were transferred by prophylactic surgery, compared with 13.9% in radiotherapy. The average in the prevention and treatment of regional lymph node metastasis
