ObjectiveTo study the epidemiologic characteristics of primary liver cancer (PLC). MethodsThe literatures about regional distribution and etiologic epidemiology of PLC were reviewed. Results PLC was mainly distributed on caostland in the south-east of China. The main cause of PLC was hepatitis B virus, aflatoxin and contamination of drinking water. Otherwise, PLS was also related with lack of some trace element, sex horemones, genealogy cause and so on.Conclusion The genesis of PLC was by multiple factors.
ObjectiveTo summarize clinical application progress of stereotactic radiotherapy for primary hepatocellular carcinoma. MethodsThe literatures about the research progress of the stereotactic radiotherapy for primary hepatocellular carcinoma were reviewed. ResultsRadiotherapy for hepatocellular carcinoma is importantly based on the radiation biology of the liver and the radiophysics of the liver cancer. Stereotactic precision radiotherapy is an effective and low toxic treatment for early hepatocellular carcinoma, moreover, it alone or in combination with microwave ablation, hepatic artery chemoembolization for unresectable hepatocellular carcinoma is safe and effective method for the treatment. ConclusionsThe optimal dose model for hepatocellular carcinoma, hepatocellular carcinoma radical dose level are problems that need further exploration, and radiobiology, radiation physics research must be strengthened to explore it, stereotactic precision radiotherapy treatment modalities in the treatment of hepatocellular carcinoma position will become increasingly people attention.
目的 探讨临床治疗原发性肝癌合并门静脉癌栓的有效方法及疗效。方法 对我院2008年1月至2010年1月期间收治的29例原发性肝癌合并门静脉癌栓患者的临床资料进行回顾性分析,并按治疗方法的不同将患者分为经动脉导管栓塞术（TAE）治疗组和TAE＋门静脉灌注化疗治疗组，比较2组患者的治疗效果。结果 TAE治疗组治疗有效率、门静脉癌栓缩小率和AFP转阴率分别为43.75%、18.75%和37.50%，TAE＋门静脉灌注治疗组分别为76.92%、61.54%和61.54%，2组比较后者优于前者（P＜0.05）。TAE＋门静脉灌注治疗组患者治疗后半年及1年生存率高于TAE治疗组（P＜0.05）。TAE治疗组患者生存时间为４～18个月，中位生存期为8个月；TAE＋门静脉灌注治疗组患者生存时间为5～18个月，中位生存期为11个月。结论 TAE＋门静脉灌注化疗是一种安全可行的治疗方法，可延长原发性肝癌合并门静脉癌栓患者的生存时间。
ObjectiveTo discuss the effects of diabetes mellitus (DM) on gastrointestinal hormone changes before and after hepatocellular carcinoma (HCC) operation. MethodsThe clinical data of 143 patients with HCC treated in this hospital from April 2007 to Febuary 2010 were analyzed, which 43 patients with DM (DM group) and 100 patients without DM (NDM group). Gastrin (GAS) and motilin (MTL) levels were measured on day 3 before operation and on day 1, 2, and 7 after operation. Results① The blood MTL levels decreased and GAS levels increased on day 1, 2, and 7 after operation as compared with the levels before operation (all Plt;0.05). ② The blood MTL level and GAS level before operation in the DM group was higher than that in the NDM group (Plt;0.05), MTL level decreased while GAS level increased more significantly on day 1, 2, and 7 after operation (Plt;0.05). ③ The first anus exhausting time of patients with NDM was much earlier than that with DM (Plt;0.05). ④ The first anus exhausting time with DM over 10 years and fasting plasma glucose over 10 mmo1/L was obviously extended (Plt;0.05). ConclusionDM affectes GAS and MTL level changes after HCC operation, recovery of gastrointestinal function would be delayed if patients with long course of DM and poor control of plasma glucose.

Objective To improve the prognosis of primary liver cancer with portal vein tumor thrombus （PVTT）， the progress of treatment for primary liver cancer with PVTT was reviewed. Methods The therapeutic approach and its efficacy for primary liver cancer with PVTT were summarized by literature search within recent years. Results PVTT is a common complication of primary liver cancer， the therapeutic approach are surgical resection， transcatheter arterial chemoembolization (TACE), intraportal venous therapy， radiotherapy， ablation therapy, molecular targeted therapy， etc. The excision rate for primary liver cancer with PVTT is low， the treatment is difficult and the outcome is dismal. It remains a poor prognosis at present， and the therapeutic effect need to be promoted. Conclusions The main treatment for primary liver cancer with PVTT should be surgical excision combine with other multidisciplinary comprehensive treatment to improve the survival in patients with PVTT， moreover， the therapeutic approach should be individualized and sequentially according to the patient’s condition and the type of PVTT.
ObjectiveTo explore the relation between preoperative serum gamma-glutamyl transpeptidase to platelet ratio (GPR) and overall survival (OS) of patients with hepatitis B virus-associated hepatocellular carcinoma (Abbreviated as “patients with HCC”), and to establish a nomogram for predicting OS. MethodsAccording to the inclusion and exclusion criteria, the clinicopathologic data of patients with HCC who underwent radical resection in the Department of Hepatobiliary Surgery of Xianyang Central Hospital, from January 15, 2012 to December 15, 2018, were retrospectively analyzed. The optimal critical value of GPR was determined by receiver operating characteristic curve, then the patients were divided into a low GPR group (GPR was optimal critical value or less ) and high GPR group (GPR was more optimal critical value). The Kaplan-Meier method was used to draw the survival curve and analyze the OS of patients. The univariate and multivariate Cox proportional hazards regression model were used to analyze the factors influencing prognosis in the patients with HCC. According to the risk factors of OS for patients with HCC, a nomogram was established. The consistency index and calibration curve in predicting the 3-year and 5-year accumulative OS rates of patients with HCC were evaluated. ResultsA total of 213 patients were gathered. The optimal critical value of GPR was 0.906. There were 114 patients in the low GPR group and 99 patients in the high GPR group. The Kaplan-Meier survival curve analysis showed that the 1-, 3- and 5-year accumulative OS rates were 99.1%, 81.8%, 60.6% in the low GPR group, respectively, which were 74.2%, 49.1%, 35.7% in the low GPR group, respectively. The OS curve of the low GPR group was better than that of the high GPR group (χ2=25.893, P<0.001). The multivariate analysis results showed that the microvascular invasion, incomplete capsule, intraoperative bleeding ＞1 000 mL, postoperative complications, GPR >0.906, low tumor differentiation, and late TNM stage did not contribute to accumulative OS in the patients with HCC (P<0.05). The consistency index (95%CI) of the nomogram in predicting accumulative OS rates at 3- and 5-year for patients with HCC were 0.761 (0.739, 0.783) and 0.735 (0.702, 0.838), respectively. The calibration curves of 3- and 5-year accumulative OS rates of the nomogram were in good agreement with the actual results. ConclusionsPreoperative GPR is associated with OS, and patients with higher GPR have worse prognosis. The nomogram based on GPR has a good accuracy and differentiation.
