考察胰腺癌患者术后营养状况并对相关特征进行分析。

选取2015年1月至2018年6月手术治疗的肿瘤患者149例进行回顾性研究，其中胰腺癌患者105例归为胰腺癌组，其他类型肿瘤患者44例为对照组。应用SPSS 19.0统计学软件对数据进行统计学分析，生化指标、人体测量指标、营养学相关指标等计量资料采用(±s)表示，组间比较采用两独立t或t’检验。性别、胰腺癌类型、首发症状等计数资料组间比较采用χ²检验。以P<0.05表示差异具有统计学意义。

105例胰腺癌患者中，首发症状占比最高的为上腹痛(51.43%)、其次为腹胀(12.38%)，第三为黄疸(11.43%)；与对照组相比，胰腺癌组患者的上臂中点周径和三头肌皮褶厚度显著增加，而握力显著降低(P<0.05)；与对照组相比，胰腺癌组患者的Hb、ALB、TP和PAB含量均显著降低，而TG和TC水平显著提高(P<0.05)；与营养良好组相比，营养不良组患者的住院天数及住院费用均显著增加，而KPS得分显著降低，差异有统计学意义(P<0.05)。

相比与其他普外科恶性肿瘤，胰腺癌患者的营养不良发生率高，蛋白水平低，预后较差。

To investigate the postoperative nutritional status and the feature analysis of patients with pancreatic cancer.

From January 2015 to June 2018, 149 patients with tumors were enrolled into present study. including 105 cases of pancreatic cancer (pancreatic cancer group) and 44 cases of other tumors (control group). Statistical analysis were performed by using SPSS 19.0 software. Measurement data, such as biochemical indicators, anthropometric and nutritional indicators were expressed as (±s), and were examined by using independent t test. Count data such as sex, type of pancreatic cancer and first symptom of patients were examined by chi square test. A P value <0.05 was considered as statistically significant difference.

For 105 patients with pancreatic cancer, the first symptoms accounted for the highest is epigastric pain (51.43%), secondly is abdominal distension (12.38%), thirdly is jaundice (11.43%); Compared with the control group, the arm medium circumference and riceps skinfold thickness in pancreatic cancer group significantly increased, but the grip strength significantly decreased(P<0.05). Compared with the control group, the level of Hb, ALB, TP and PAB in pancreatic cancer group significantly decreased, but TG and TC level significantly increased, with significant difference(P<0.05). Compared with the nutritional group, the length of stay and hospitalization expenses of the malnutrition group significantly increased, but the karnofsky performance status score significantly decreased, with significant difference(P<0.05).

Compared with the other cancer patients, the incidence of malnutrition such as low ALB, in patients with the pancreatic cancer is high with poor prognosis.
