Abstract:
Objective:To investigate the survival prognosis of patients with primary liver cancer and its influencing factors.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 3 106 patients with primary liver cancer who had health insurance for special illness in the Chongqing Malignant Tumor Treatment System from January 2000 to August 2018 were collected. There were 2 559 males and 547 females, aged (60±13)years, with a range from 19 to 95 years. Observation indicators: (1) demographic characteristics; (2) clinical treatment and pathological examination; (3) follow-up and survival; (4) analysis of prognostic factors. Follow-up using telephone interview, outpatient or inpatient reexamination was preformed to detect survival of patients. Follow-up was done once every 3 months within the first year and once a year thereafter up to December 2018. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represent as M (range). Count data were expressed as absolute numbers or percentages. Survival analysis was done after excluding missing data of follow-up. The survival rate was calculated and survival curve was drawn by Kaplan-Meier method. The prognostic factors were analyzed after excluding missing data of follow-up, pathological type, and TNM staging. The log-rank test was used for univariate analysis, and COX proportional hazard model was used for multivariate analysis. Results:(1) Demographic characteristics: of the 3 106 patients with primary liver cancer, the number of males and females (gender), cases with age < 30 years, from 30 to 44 years, from 45 to 59 years, from 60 to 74 years, ≥75 years, cases of Han nationality or other ethnic groups, cases being married or other status (marital status), cases with occupation as enterprise unit staff and (or) workers, public institution personnel and (or) civil servants, freelancers and (or) self-employed entrepreneurs, unemployed, company staff, and other professionals were 2 559, 547, 35, 362, 1 131, 1 163, 415, 3 053, 53, 2 896, 210, 880, 342, 130, 101, 124, and 1 529, respectively. (2) Clinical treatment and pathological examination: of the 3 106 patients with primary liver cancer, cases with hospitalization time < 10 days, from 10 to 19 days, from 20 to 29 days, ≥30 days, cases without surgery or with surgery, cases with hepatocellular carcinoma, cholangiocarcinoma, hybrid type and other pathological types, cases of stage Ⅰ, Ⅱ, Ⅲ, Ⅳ of TNM staging were respectively 771, 1 312, 661, 362, 915, 2 191, 836, 63, 24, 29, 28, 90, 624. There were 2 183 out of 3 106 patients without pathological data and 2 335 without TNM staging data. (3) Follow-up and survival: of the 3 106 patients with primary liver cancer, 2 561 were followed up for 3.0-96.0 months, with a median follow-up time of 27.6 months. The 2 561 patients had survived for 1.0-96.0 months, with a median survival time of 24.7 months. The 1-, 3-, 5-year survival rates were 63.2%, 42.3%, 29.5%, respectively. (4) Analysis of prognostic factors: results of univariate analysis showed that age, marital status, occupation, hospitalization time, surgical treatment, pathological types, and TNM staging were related factors for prognosis of patients ( χ2=31.820, 6.752, 39.100, 120.889, 226.700, 10.452, 48.602, P<0.05). Results of multivariate analysis showed that being married, hospitalization time no less than 30 days, surgical treatment were independent protective factors for prognosis ( hazard ratio=1.463, 0.572, 0.575, 95% confidence interval: 1.044-2.049, 0.413-0.793, 0.438-0.755, P<0.05), stage Ⅲ and Ⅳ of TNM staging were independent risk factors for prognosis of patients ( hazard ratio=3.941, 5.036, 95% confidence interval: 1.687-9.211, 2.237-11.335, P<0.05). Conclusions:Patients with primary liver cancer have poor prognosis. Being married, hospitalization time no less than 30 days, and surgical treatment are independent protective factors for prognosis, stage Ⅲ and Ⅳ of TNM staging are independent risk factors for prognosis.
