血清白蛋白及尿素氮水平与肺癌不同临床病理特征和预后的关系

背景与目的 肺癌作为全球男女性中致死率最高的肿瘤之一,严重威胁着人类的健康.本研究旨在分析肺癌患者血清白蛋白及尿素氮水平与临床病理特征及生存期的关系.方法 收集2008年1月-2013年12月四川大学华西医院病理确诊原发性肺癌患者1,098例,检测患者血清中白蛋白及尿素氮水平,按检测水平是否正常分为阳性组及阴性组,分别分析白蛋白及尿素氮水平与肺癌临床病理特征及生存期的相关性.结果 1,098例患者的年龄、性别、病理学分型、肝转移、胸膜转移与血清白蛋白水平差异有统计学意义(P<0.05);312例鳞癌患者的年龄、肺内转移以及612例腺癌患者的年龄、性别、临床分期、胸膜转移与白蛋白水平差异有统计学意义(P<0.05).尿素水平与各临床特征均无统计学意义.不同病理学类型的肺癌患者血清白蛋白水平在阴性组与阳性组中位生存时间分别为鳞癌36个月和19个月,腺癌35个月和15个月,前者中位生存期明显高于后者.尿素氮水平与肺癌患者生存期无相关性.结论 多种影响因素与血清白蛋白阳性程度相关,血清白蛋白水平与肺癌的生存相关,其是肺癌患者预测预后的一个指标.

Relationships between Serum Albumin and Urea Level and the Clinical Pathological Characteristics and Survival Time in Patients with Lung Cancer

Background and objective Lung cancer is the most common malignancy and is the leading cause of cancer-related death worldwide. Thus, this disease severely threatens human health. This study aims to identify the relationships between serum albumin and urea level and the clinical pathological characteristics and survival time in patients with lung can-cer.Methods A total of 1,098 patients with lung cancer were diagnosed by pathology and tested the serum albumin and urea level in West China Hospital of Sichuan University during January 2008 to December 2013. According to the levels of albumin and urea, patients were divided into the normal level group (negative group) and abnormal level group (positive group). The differences of patients' clinical pathological characteristics and survival time in the two groups were analyzed.Results Differ-ences in age, sex, histological classification, liver metastasis and pleural metastasis were statistically significant between the two groups of serum albumin (P<0.05). Differences in age, intrapulmonary metastasis of 312 patients of squamous cell carcinoma and differences in age, sex, stages, pleural metastasis of 612 patients of adenocarcinoma between the two groups of serum al-bumin (P<0.05). There were no significant differences between the two groups of urea. In different histological classification between the two groups of serum albumin, the median survival period of squamous cell carcinoma was 36 months and 19 monthes, adenocarcinoma was 35 months and 15 monthes, the abnormal group were all significantly lower than those in the normal group. The median survival period was no significant difference between the two groups of urea.Conclusion The level of serum albumin is an important indicator for prognosis.
