Shenqifuzheng injection combined with chemotherapy in the treatment of advanced gastric cancer: a systematic review and meta-analysis.

OBJECTIVE The aim of this systematic review and meta-analysis was to evaluate the clinical efficacy of Shenqifuzheng (SQFZ) injection combined with chemotherapy in the treatment of advanced gastric cancer. MATERIALS AND METHODS We conducted an electronic search by using PubMed, EMBASE, ASCO, ESMO and Chinese National Knowledge Infratructure (CNKI), databases. The randomized controlled trials about Shenqifuzheng injection combined with chemotherapy versus chemotherapy alone in the treatment of advanced gastric cancer were reviewed and collected. Pooled odds ratio (OR) for the response rate and KPS improvement were calculated using the software MetaAnalyst 3.1. RESULTS Fifteen trials met our inclusion criteria and finally included in this meta-analysis. The objective response rate (ORR) in patients treated with Shenqifuzheng injection combined with chemotherapy was much higher than that of chemotherapy only (OR = 1.66, 95% CI: 1.20-2.29) with statistical significance (P < 0.05). The pooled data showed the combined treatment can significant increase the Karnofsky score (KPS) compared with the chemotherapy only (OR = 3.74, 95% CI: 2.66-5.27 (P < 0.05). CONCLUSION SQFZ injection combined with chemotherapy treatment regimen can improve the clinical efficacy and performance status in patients with advanced gastric cancer compared with chemotherapy alone.

Is the incidence of postoperative anastomotic leakage different between laparoscopic and open total mesorectal excision in patients with rectal cancer? A meta-analysis based on randomized controlled trials and controlled clinical trials.

OBJECTIVE The purpose of this meta-analysis was to assess whether the incidence of postoperative anastomotic leakage (PAL) was different between laparoscopic and open total mesorectal excision (TME) in patients with rectal cancer. MATERIALS AND METHODS The PubMed, Medline, Cochrane Library, Wanfang and China National Knowledge Infrastructure databases were searched for selecting the randomized controlled trials (RCTs) and controlled clinical trials (CCT) on the incidence of PAL between laparoscopic and open TME for rectal cancer. The incidence rate of PAL was extracted from each of the individual study and pooled by the STATA-11.0 statistical software. RESULTS Six RCTs and 19 CCTs were included in this meta-analysis. The pooled results indicated that no statistical difference of PAL rate was found between aparoscopic and open TME in patients with rectal cancer (odds ratio [OR] =0.81, 95% confidence interval [CI]: 0.61-1.07, [P > 0.05]); The sub-group analysis when pooling the RCTs and CCTs respectively also indicated that there was no statistical difference of PAL rate between the laparoscopic and open TME (OR = 0.70, 95% CI: 0.35-1.39, [P > 0.05] for RCTs and OR = 0.84, 95% CI: 0.61-1.14, [P > 0.05]). CONCLUSION Based on present studies, laparoscopic TME does not increase the risk of PAL.

Safety of implanting sustained-release 5-fluorouracil into hepatic cross-section and omentum majus after primary liver cancer resection.

This study was designed to evaluate the short-term safety of implanting sustained-release 5-fluorouracil (5-FU) into hepatic cross-section and omentum majus after primary liver cancer resection and its impact on related indexes of liver. Forty patients were selected and divided into an implantation group (n = 20) and a control group (n = 20). On the first day after admission, first week after surgery, and first month after surgery, fasting venous blood was extracted from patients for measuring hematological indexes. The reduction rate of alpha fetoprotein (AFP) on the first week and first month after surgery was calculated, and moreover, drainage volume of the abdominal cavity drainage tube, length of stay after surgery, and wound healing condition were recorded. We found that levels of alanine aminotransferase, aspartate amino transferase, blood urea nitrogen, creatinine, total bilirubin, albumin, and white blood cells measured on the first week and first month after surgery, length of stay, and wound healing of patients in the two groups had no significant difference (P >0.05). Drainage volume and reduction rate of AFP of two groups were significantly different on the first week and first month after surgery (P <0.05). Implanting sustained-release 5-FU into hepatic cross-section and omentum majus after primary liver cancer resection is proved to be safe as it has little impact on related indexes.

Systemic Analysis on Laparoscope-Assisted Gastrectomy for Patients with Gastric Cancer

BACKGROUND Laparoscope-assisted gastrectomy in treating patients with gastric cancers developed with a background of highly invasive traditional surgery and is being increasingly performed in the Asian Pacific area. This study systemically investigated the technique and clinical results for comparison with traditional radical subtotal gastrectomy for gastric cancers. METHODS Clinical studies evaluating the effectiveness and side effects of laparoscope-assisted gastrectomy in treating patients with gastric cancers were identified using a predefined search strategy. Summary rates of effectiveness and side effects of laparoscope-assisted gastrectomy were calculated. RESULTS Thirteen clinical studies which including 1,412 patients with gastric cancer treated by laparoscope-assisted gastrectomy were considered eligible for inclusion. Systemic analysis showed that, for all patients, the pooled resection rate was 100%. Major adverse effects were anastomotic stenosis, abdominal abscess, abdominal bleeding, postoperative ileus. Treatment related death occurred in 0. 71% (10/1412). CONCLUSION This systemic analysis suggests that laparoscope-assisted gastrectomy in treating patients with gastric cancers is associated with good curative rate and acceptable complications.
