Effects of S-1 combined with radiotherapy in the treatment of advanced esophageal cancer: A systematic review and meta-analysis protocol

Neoadjuvant chemotherapy with S-1 plus cisplatin for esophageal squamous cell carcinoma

S-1 shows good efficacy for esophageal squamous cell carcinoma (ESCC) under single use or combined with cisplatin or radiotherapy. The S-1 plus cisplatin (SP) regimen is one of the chemotherapy candidates for ESCC. However, the efficacy of the SP regimen for neoadjuvant chemotherapy (NAC) has not been verified. The aim of this study was to investigate the feasibility and efficacy of NAC with SP for advanced ESCC. In this study, patients with clinical stage II/III/IV ESCC received NAC with SP regimen from June 2016 to July 2020 in Ogaki Municipal Hospital were retrospectively evaluated. In the SP regimen, S-1 80 mg/m² was administered on days 1-14, and cisplatin was administered 70 mg/m² on day 1, repeated every 4 weeks, for two cycles. The completion rate, clinical and pathological response rate, adverse events, and long-term outcomes were analyzed. 43 ESCC patients were diagnosed clinical stage II/III/IV ESCC. Among the 43 patients, 31 patients underwent NAC with SP regimen. The completion rate was 93.5%. The clinical response and pathological response rates (grade 2 or 3) were 83.9% and 32.3%, respectively. Seven patients (22.6%) had a pathological complete response (grade 3). Grade 3 neutropenia was observed in 33.7% of cases. No other grade 3 cases or higher toxicity was observed. The 3-year relapse-free and overall survival rates were 52.6% and 65.6%, respectively. NAC with SP is a feasible and effective treatment strategy for advanced. ESCC. The antitumor response could be higher than that under the cisplatin plus 5-fluorouracil regimen.

Brucea javanica oil emulsion injection (BJOEI) as an adjunctive therapy for patients with advanced colorectal carcinoma: A protocol for a systematic review and meta-analysis

BACKGROUND

Brucea javanica oil emulsion injection (BJOEI) has been widely applied as a promising adjunctive drug for colorectal carcinoma (CRC). However, the exact effects and safety of BJOEI remains controversial. In this study, we aimed to summarize the efficacy and safety of BJOEI for the treatment of advanced CRC through the meta-analysis, in order to provide scientific reference for the design of future clinical trials.

METHODS

Eligible prospective controlled clinical trials were searched from PubMed, Cochrane Library, Google Scholar, Medline, Web of Science (WOS), Excerpt Medica Database (Embase), Chinese BioMedical Database (CBM), China Scientific Journal Database (VIP), China National Knowledge Infrastructure (CNKI) and Wanfang Database. Papers in English or Chinese published from January 2000 to May 2020 will be included without any restrictions. The clinical outcomes including therapeutic effects, quality of life (QoL), immune function and adverse events, were systematically evaluated.Study selection and data extraction will be performed independently by 2 reviewers. Review Manager 5.3 and Stata 14.0 were used for data analysis, and a fixed or random-effect model will be used depending upon the heterogeneity observed between trials. Subgroup and meta-regression analysis will be carried out depending on the availability of sufficient data.

RESULTS

The results of this systematic review will be published in a peer-reviewed journal.

CONCLUSION

Our study will draw an objective conclusion of the effects and safety of BJOEI for advanced CRC, and provide a helpful evidence for clinicians to formulate the best postoperative adjuvant treatment strategy for CRC patients.INPLASY registration number: INPLASY202060014.

Xiaoaiping injection as adjunct therapy for patients with advanced esophageal carcinoma: A protocol for a systematic review and meta-analysis

BACKGROUND

Esophageal carcinoma (EC) is one of the worst malignant digestive neoplasms with a strong tendency of invasion and metastasis. Despite the improvement of diagnostic and therapeutic methods in the past decades, the prognosis of EC remains unsatisfactory. Xiaoaiping injection (XAPI), a famous traditional Chinese herbal medicine, has been widely applied as a promising adjunctive drug for EC. However, the exact effects and safety of XAPI have yet to be systematically investigated. We aimed to summarize the efficacy and safety of XAPI for the treatment of advanced EC through the meta-analysis, in order to provide scientific reference for the design of future clinical trials.

METHODS

Relevant randomized controlled trials (RCTs) were searched from Cochrane Library, PubMed, Google Scholar, Web of Science, Excerpt Medica Database, Medline, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, China Scientific Journal Database and Wanfang Database. Papers in English or Chinese published from January 2000 to May 2020 will be included without any restrictions.Study selection and data extraction will be performed independently by 2 investigators. The clinical outcomes including overall response rate, complete response rate, overall survival, Disease-free survival, quality of life, immune function and adverse events, were systematically evaluated. Review Manager 5.3 and Stata 14.0 were used for data analysis, and the quality of the studies was also evaluated.

RESULTS

The results of this study will be published in a peer-reviewed journal, and provide more evidence-based guidance in clinical practice.

CONCLUSION

Our study will draw an objective conclusion of the effects of XAPI combined with conventional treatment for advanced EC and provide a helpful evidence for clinicians to formulate the best postoperative adjuvant treatment strategy for EC patients.
