Advances in surgical management of primary carcinoma of the gallbladder: Results from 10-year research at a single institution / 西安交通大学学报(医学版)

【Objective】 To analyze the clinical characteristics of patients with primary carcinoma of the gallbladder (PGC) who underwent radical intent resection in our center in the last decade and the therapeutic effects of the operation. 【Methods】 A single-institution database of The First Affiliated Hospital of Xi'an Jiaotong University from January 2008 to December 2017 was queried for patients with PGC who had received surgical treatment. The data were studied retrospectively to assess the trend of total admission, radical resection rate, prognosis and clinicopathological characteristics of PGC in the last decade. 【Results】 A total of 2 159 patients with PGC were treated in our institution from 2008 to 2017. Of them, 1072 were surgically treated and 503 underwent radical intent resection. In the past 5 years (2013-2017), the radical resection rate was 26.5% (319 cases of the operation), which was significantly higher than that in 2008-2012 (19.2%) (P<0.001). The overall survival time of the patients who underwent radical resection was 32 months, and the 1-, 3-, and 5-year survival rate was 68.9%, 48.4% and 41.6%, respectively. Compared with the data of 2008-2012, the proportion of the patients with preoperative jaundice decreased in the past 5 years (7.8% vs. 14.7%, P<0.05), that of the patients who underwent D2 lymphadenectomy (74.0% vs. 26.1%, P<0.001) increased significantly (P<0.001), the total number of lymph nodes obtained from the dissection (8.07±5.18 vs. 5.89±3.14, P<0.001) increased significantly (95.6% vs. 89.7%, P<0.05), and the proportion of R0 resection (95.6%) increased significantly (P<0.05). 【Conclusion】 The diagnosis and treatment of radical intent resection of PGC in our hospital have changed significantly in the last decade, mainly reflected in the extension of lymphadenectomy, increase in R0 resection rate and decrease in patients with preoperative jaundice.

Progress in diagnosis and treatment of gallbladder carcinoma in the past 60 years / 西安交通大学学报(医学版)

The First Affiliated Hospital of Xi’an Jiaotong University has experienced more than 60 years’ history in the diagnosis and treatment of gallbladder carcinoma (GBC). From 1956 to 2018, 3 430 cases of GBC were treated, including 1941 cases of surgical treatment and 703 cases of radical resection. The data comparison between 1956-2008 and 2009-2018 revealed that the radical resection rate increased from 19.9% to 48.3%. The mean survival time after regional radical resection and extended radical resection was (23.1±15.4) and (17.5±16.2) months, respectively, from 2004 to 2008. Compared with those between 2013 and 2017, the mean survival time after regional radical resection and extended radical resection was (31.5±2.0) and (18.6±3.9) months, respectively, and the median survival time was 31.0 and 11.0 months, respectively. By comparing the GBC data longitudinally, the mode of diagnosis and treatment of GBC in our hospital has changed significantly in the past 10 years, which is mainly reflected in the change of GBC staging system, the progress of imaging diagnosis mode, the standardization of surgery and the development of adjuvant treatment. All of these have significantly improved the prognosis of GBC.

respectively 29.5 months (range,0.5-69.9 months),71.6％ and 45.8％.One hundred and twenty-two patients died during the follow-up.(5) Prognostic factors analysis:the results of univariate analysis showed that preoperative level of bilirubin,pathological type,degree of tumor differentiation,liver invasion,vascular invasion,nerve invasion,T staging,N staging and postoperative chemotherapy were factors affecting prognosis of patients with primary GBC (x2 =10.26,3.96,45.89,34.64,12.75,27.05,35.09,39.44,4.40,P＜0.05).The results of multivariate analysis showed that low-differentiated tumor,liver invasion and N2 staging were independent risk factors affecting prognosis of patients with primary GBC [odds ratio (OR)=1.90,1.71,1.46,95％ confidence interval (CI):1.34-2.70,1.15-2.52,1.17-1.82,P＜0.05],and postoperative chemotherapy was a protective factor affecting prognosis of patients with primary GBC (OR=0.35,95％ CI:0.15-0.82,P＜0.05).Conclusions For patients with primary GBC undergoing radical resection,D2 lymph node dissection should be performed routinely.The low-differentiated tumor,liver invasion and N2 staging are independent risk factors affecting prognosis of patients,and postoperative chemotherapy is a protective factor.

Inhibitory effect of rapamycin on proliferation of H_(22) hepatic cancer in mice / 西安交通大学学报(医学版)

Objective To explore rapamycin's inhibitory effect on proliferation of H_(22) hepatic cancer in mice. Methods In vitro study: H_(22) hepatic cancer cell lines were cultured with rapamycin, CsA, FK506, and proliferation was determined through MTT. The influences of different agents on the H_(22) hepatic cancer cell cycle were observed by flow cytometry. The vascular endothelial growth factor (VEGF) concentration of the supernatant fluid of the cultured H_(22) hepatic cancer cell was detected by ELISA. In vivo study: C57BL/6 to Balb/c mice allogenic skin transplant was established, and the H_(22) hepatic cancer cell was implanted under skin. Rapamycin, CsA, FK506 and 5-FU were fed to the mice, respectively. The effect of different immunosuppressors on the survival of skin graft was observed while the proliferation of the transplant tumor was investigated. VEGF concentration of treated mice serum was examined by ELISA. The microvessel density of the transplanted tumor was observed through immunohistochemistry staining of CD34. Results The proliferation of the H_(22) hepatic cancer cells was inhibited by rapamycin at the concentration different dose of rapamycin, the VEGF concentration of the supernatant fluid decreased significantly (P<0.05). The number of S phase cells decreased significantly compared to that of other agents (P<0.05). When rapamycin, the lengthened survival time of the skin grafts was similar to that in CsA and FK506 groups. But the tumor volume was smaller than that in CsA and FK506 groups (P<0.05). Compared to that in the control group, the VEGF concentration of mice serum decreased in rapamycin group (P<0.05), and the microvessel density of the transplant tumor was reduced greatly (P<0.05). Conclusion Rapamycin, as an immunosuppressor, significantly resists immunologic rejection and inhibits the proliferation of H_(22) hepatic cancer, thus having its advantage in treating malignant hepatic cancer with liver transplantation.
