ABSTRACT
BACKGROUND: Sarcomatoid intrahepatic cholangiocarcinoma (SICC) is an extremely rare and highly invasive malignant tumor of the liver. The precise pathologic mechanism of SICC has not been clearly identified, and the prognosis is very poor. The effectiveness of the treatment strategy of radical hepatectomy combined with Huaier granules has not yet been reported. CASE SUMMARY: The patient was a 69-year-old male who presented with intermittent right upper abdominal pain for one month and 4-pound weight loss before admission. Abdominal magnetic resonance imaging and magnetic resonance cholangiopancreatography showed multiple stones in the bile ducts accompanied by dilatation of the intrahepatic and extrahepatic bile ducts. The preoperative diagnoses were right intrahepatic bile duct stones and extrahepatic bile duct stones; thus, surgical resection was performed. Choledochoscopy showed that the bile duct wall of the right anterior lobe was thickened, and a mass was visible in the duct. Then, a biopsy was performed, and rapid frozen-section biopsy analysis indicated that the tumor was malignant. The final diagnosis was SICC (T1aN0M0). Huaier granules were taken by the patient as anticancer therapy after surgery. The patient attended follow-up for 72 mo with no tumor recurrence or metastasis. CONCLUSION: Sarcomatous intrahepatic cholangiocarcinoma is an extremely rare, aggressive malignancy, and the diagnostic gold standard is pathological diagnosis. We reported the first case of successful treatment with Huaier granules as anticancer therapy after surgery, which indicated that Huaier granules are safe and effective. Further studies are needed to study the anticancer molecular mechanisms of Huaier granules in sarcomatous intrahepatic cholangiocarcinoma.
ABSTRACT
BACKGROUND: The objective of this study was to evaluate the feasibility, safety, and potential benefits of laparoscopic gastrectomy (LG) comparing with open gastrectomy (OG) in elderly population. METHODS: Studies comparing LG with OG for elderly population with gastric cancer, published between January 1994 and July 2015, were identified in the PubMed, Embase, and ISI Web of Science databases. Operative outcomes (intraoperative blood loss, operative time, and the number of lymph nodes harvested) and postoperative outcomes (time to first ambulation, time to first flatus, time to first oral intake, postoperative hospital stay, postoperative morbidity) were included and analyzed. The Newcastle-Ottawa Scale was used to assess the quality of the pooled study. A funnel plot was used to evaluate the publication bias. RESULTS: Seven studies totaling 845 patients were included in the meta-analysis. LG in comparison to OG showed less intraoperative blood loss (weighted mean difference (WMD) -127.47; 95% confidence interval (CI) -202.79 to -52.16; P < 0.01), earlier time to first ambulation (WMD -2.07; 95% CI -2.84 to -1.30; P < 0.01), first flatus (WMD -1.04; 95% CI -1.45 to -0.63; P < 0.01), and oral intake (WMD -0.94; 95% CI -1.11 to -0.77; P < 0.01), postoperative hospital stay (WMD -5.26; 95% CI -7.58 to -2.93; P < 0.01), lower overall postoperative complication rate (odd ratio (OR) 0.39; 95% CI 0.28 to 0.55; P < 0.01), less surgical complications (OR 0.47; 95% CI 0.32 to 0.69; P < 0.01), medical complication (OR 0.35; 95% CI 0.22 to 0.56; P < 0.01), incisional complication (OR 0.40; 95% CI 0.19 to 0.85; P = 0.02), and pulmonary infection (OR 0.49; 95% CI 0.26 to 0.93; P = 0.03). No significant differences were observed between LG and OG for the number of harvested lymph nodes. However, LG had longer operative times (WMD 15.73; 95% CI 6.23 to 25.23; P < 0.01). CONCLUSIONS: LG is a feasible and safe approach for elderly patients with gastric cancer. Compared with OG, LG has less blood loss, faster postoperative recovery, and reduced postoperative morbidity.
