ObjectiveTo analyze effect of percutaneous transhepatic choledochus drainage (PTCD) for hilar cholangiocarcinoma. MethodsClinical data of 67 cases of hilar cholangiocarcinoma who treated in our hospital from Jan. 2005 to Dec. 2010 were retrospectively analyzed. ResultsOf the 67 cases, 30 cases were performed PTCD, 20 cases were performed radical surgery after PTCD, and 17 cases were performed palliative surgery after PTCD. There were 59 cases who were followed-up for 3-30 months, and the median time was 9.3 months. The median survival time of patients who underwent PTCD, radical surgery, and palliative surgery were 10.2, 21.4, and 8.9 months respectively. The survival of patients who underwent radical surgery was better than those of underwent PTCD (χ2=13.6, P=0.000 4) and palliative surgery (χ2=15.2, P=0.003 8), and survival of patients who underwent PTCD was better than patients underwent palliative surgery (χ2=5.3, P=0.040 1). ConclusionsPTCD is contribute to preoperative diagnosis and evaluation, in addition, it can reduce unnecessary surgical exploration, guarantee the safety of the radical surgery, and provide follow-up care for palliative operation channel which is favorable for local internal radiation therapy.

Objective To analyze clinical value of early enteral nutrition following radical resection of gastric cancer. Methods Seventy-six patients with gastric cancer underwent radical resection from May 1, 2016 to July 1, 2016 in the West China Hospital of Sichuan University were included according to the inclusion criteria and exclusion criteria, then were randomly divided into observation group (36 cases) and control group (40 cases). The patients in the observation group received the enteral nutrition on day 2 following the surgery, in the control group received the conventional management. The gastrointestinal recovery and the adverse reaction were compared in these two groups. The preoperative and postoperative laboratory indicators and the body weight of the patients in both groups were analyzed. Results ① The general data such as age, gender, and body weight had no significant differences in these two groups (P>0.05). ② The first anus exhaust time and the first defecation time of the observation group were significantly shorter than those of the control group (P<0.05). ③ The adverse reaction rate of the observation group was significantly lower than that of the control group (P<0.05). ④ On admission, the serum albumin, urea nitrogen, creatinine, and lymphocyte count had no significant differences in these two groups (P>0.05). On day 5 after the operation, the serum albumin of the observation group was significantly higher than that of the control group (P<0.05). ⑤ The body weight had no significant difference in these two groups before the operation (P>0.05), which in the observation group was significantly heavier than that of the control group on day 30 after the operation (P<0.05). Conclusion Preliminary results of limited cases in this study show that early enteral nutrition following radical resection of gastric cancer is safe and effective, it could promote gastrointestinal function resumption and effectively improve nutritional status.

ObjectiveTo investigate the risk factors and establish the predictive pattern of the metachronous liver metastasis after curative surgery for patientswith gastric cancer. MethodsThe clinicopathologic data of patients who underwent radical gastric cancer surgery and met the inclusion and exclusion criteria from January 1, 2015 and January 1, 2018 in the First Hospital of Lanzhou University were retrospectively analyzed. The risk factors affecting metachronous liver metastasis of gastric cancer were screened out by univariate and multivariate logistic regression analysis. And a nomogram prediction model based on the risk factors screened out was established and its predictive efficiency was evaluated. ResultsA total of 203 patients were collected in this study, of whom 41 (20.4%) developed metachronous liver metastasis of gastric cancer. The results of multivariate logistic regression analysis showed that the tumor diameter ≥5 cm, increasing intraoperative bleeding, carcinoembryonic antigen (CEA) ≥5 μg/L, and lymphovascular invasion increased the risks of metachronous liver metastasis of gastric cancer (all P<0.05). The area under the receiver operating characteristic curve and its 95% confidence interval (95%CI) of the nomogram based on these risk factors in predicting metachronous liver metastasis of gastric cancer was 0.850 (0.793, 0.908), and the consistency index (95%CI) was 0.812 (0.763, 0.859). The calibration curve for predicting the risk of metachronous liver metastasis in gastric cancer by the nomogram was close to the 45° ideal curve and had a stronger calibration (Hosmer Limeshow goodness-of-fit test, χ2=2.116, P=0.347). ConclusionsThe results of this study conclude metachronous liver metastasis of gastric cancer is not low, and the patient with lymphovascular invasion, higher level of CEA (≥5 μg/L), more intraoperative bleeding, and larger tumor diameter (≥5 cm) has a higher risk of metachronous liver metastasis of gastric cancer. The nomogram prediction model established based on these risk factors has a good predictive efficiency and can provide reference for clinicians to identify high-risk patient and take early interventions.
ObjectiveTo explore the application of MDT mode in the diagnosis and treatment of a large retroperitoneal small cell carcinoma.MethodsA huge retroperitoneal tumor about 25 cm×18 cm was found by the preoperative abdominal MRI examination, which was considered as the malignant tumor. Considering the patient’s condition, MDT consultation of the specialists in radiology, oncology, vascular surgery, urinary surgery, and anesthesiology was conducted.ResultsBy MDT discussion, the general condition of patient was good. At present, the diagnosis of the huge retroperitoneal tumor was confirmed. Although the tumor was surrounded with related organs closely, yet the radical operation was finished smoothly and the R0 resection was achieved through the collaboration of MDT. The operation lasted 365 minutes, and the intraoperative blood loss was about 200 mL. Postoperative pathology confirmed that the tumor margin was negative and no postoperative complication occurred. The total number of hospital stays was 23 days. The patient’s return to the hospital for review in 4 months after discharge revealed a tumor recurrence. Then, combined with radiotherapy and chemotherapy, the patient’s condition was stable during treatment.ConclusionFor rare cases of retroperitoneal small cell carcinoma involving multiple disciplines, the treatment based on MDT is able to bring better clinical outcome to patients due to safer and more feasible.
ObjectiveTo systematically review the efficacy and safety of neoadjuvant chemotherapy containing tegafur gimeracil oteracil potassium (S-1) combined with surgery in the treatment of advanced gastric cancer.MethodsWe searched EMbase, PubMed, The Cochrane Library, Web of Science, CBM, CNKI and WanFang Data from inception to February 2017, to collect randomized controlled trials (RCTs) about neoadjuvant chemotherapy containing S-1 combined with surgery in the treatment of advanced gastric cancer. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 11 RCTs involving 971 advanced gastric cancer patients were included. The results of meta-analysis showed that the neoadjuvant chemotherapy containing S-1 combined with surgery group was superior to the control group in R0 resection rate (OR=2.75, 95%CI 1.91 to 3.95, P<0.000 01), 2 year survival rate (OR=1.72, 95%CI 1.01 to 2.93, P=0.05) and 3 year survival rate (OR=1.64, 95%CI 1.12 to 2.41, P=0.01), while there were no statistical differences in response rate (OR=1.33, 95%CI 0.70 to 2.51, P=0.39), 1 year survival rate (OR=1.50, 95%CI 0.64 to 3.53, P=0.35) and the incidence of postoperative complications (OR=1.00, 95%CI 0.66 to 1.51, P=0.98).ConclusionNeoadjuvant chemotherapy containing S-1 combined with surgery can improve the R0 resection rate, 2-year survival rate and 3-year survival rate without increase postoperative complications rate. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo find out the risk factors affecting the prognoses and microvascular invasion (MVI) of patients with China Liver Cancer Staging-stageⅠ a (CNLC Ⅰ a) hepatocellular carcinoma (HCC). MethodsBased on the established inclusion and exclusion criteria, the clinicopathologic information and follow-up data of patients with CNLC Ⅰ a HCC were retrospectively collected, who underwent radical resection in the West China Hospital of Sichuan University from Jan. 2012 to Dec. 2016. The Cox proportional hazards regression was utilized to analyze the risk factors affecting the prognosis of patients with CNLC Ⅰ a HCC, and the non-conditional logistic regression was utilized to analyze the preoperative clinical indicators associating with MVI. ResultsA total of 300 patients with CNLC Ⅰ a HCC were included in this study, among which 51 (17.0%) cases accompanied with MVI. The follow-up period ranged from 2 to 104 months (median 39 months), with a recurrence time ranging from 2 to 104 months (median 52 months), and an overall survival time ranging from 3 to 104 months (median 98 months). During the follow-up period, postoperative recurrence occurred in 145 (48.3%) cases. The Cox proportional hazards regression analysis revealed that: tumor diameter >3 cm, presences of MVI and satellite nodules increased the risk of shortened recurrence time for the patients with CNLC Ⅰ a HCC (P<0.05); Factors including gamma-glutamyltranspeptidase level >60 U/L, tumor low differentiation, presences of MVI and satellite nodules were associated with shortened overall survival time for the patients with CNLC Ⅰ a HCC (P<0.05). The preoperative alpha-fetoprotein level ≥400 μg/L and tumor diameter >3 cm increased the risk of presence of MVI for the patients with CNLC Ⅰ a HCC [χ2=3.059, OR(95%CI)=2.357(1.047, 5.306), P=0.038; χ2=3.002, OR(95%CI)=2.301(1.026, 5.162), P=0.043]. ConclusionThe results of this study suggest that adopting corresponding strategies to address the risk factors affecting prognosis of patients with CNLC Ⅰ a HCC and the risk factors associated with MVI can have a significant clinical impact on improving surgical treatment outcomes for these patients.
