肺腺鳞癌临床病理特点和外科治疗预后研究

目的探讨影响肺腺鳞癌预后的因素,为改进治疗方案奠定基础。方法对361例肺腺鳞癌患者的临床资料进行回顾性分析。选择性别、年龄、症状、病程、肿瘤部位、X线分型、肿瘤边缘、分叶、密度、手术方法、胸膜皱缩、大体标本侵及胸膜或胸壁情况、手术性质、肿瘤最大直径、淋巴结转移模式、转移度(阳性淋巴结个数/淋巴结总数)、分化程度、病理侵及胸膜或胸壁情况、病理T项、病理N项、病理分期、术后放疗、术后化疗、术后复发转移等24个非重复因素进行预后分析,生存率计算采用寿命表法。统计分析运用Log-rank检验和Cox模型多因素分析。结果本组腺鳞癌根治术后的5年、10年生存率分别为29.1%和15.4%。Log-rank检验示X线分型、手术方法,大体标本侵及胸膜或胸壁情况,手术性质、肿瘤最大直径、病理侵及胸膜或胸壁情况、病理T项、病理N项、淋巴结转移模式、转移度、病理分期、术后复发转移及术后放疗对预后有显著影响(P<0.05)。经Cox多因素分析示术后复发转移、病理分期、手术性质因素对预后影响最大。结论肺腺鳞癌是一种生物学行为恶性程度较高的非小细胞肺癌,单纯外科治疗效果尚不满意。

The Clinic-pathologic Characteristics and the Surgical Prognosis in the Lung Adenosquamous Carcinoma Patients

Objective To investigate the clinic-pathologic characteristics and the prognostic factors in the patients with lung adenosquamous carcinoma. Methods The data of 361 patients operated for lung adenosquamous carcinoma were retrospectively analyzed as to the prognostic factors through comparison of survival rates by the actuarial method.A prognostic multivariable analysis was performed,after the variables related to prognosis were seeded with prognostic univariate analyses in the 24 non-repeating possible prog...
