Lean management,when introduced to optimize emergency operations,may improve medical service.It has been proved in practice that ideas and methodology of lean management guarantee emergency services by ensuring safety and quality of emergency operation process.In addition,it minimizes costs and enhances the business and social efficiency of the hospital.

BACKGROUNDNasopharyngeal carcinoma (NPC) is a squamous-cell carcinoma especially prevailing among the natives of southern China. The regimen of concurrent chemoradiotherapy (CCRT) that include platinum and 5-fluorouracil (5-FU) is considered to be the standard treatment for NPC. However, its clinical use is limited by its toxicity. Our purpose was to evaluate the efficacy and safety of the regimen of CCRT with taxanes and platinum versus the regimen of CCRT with 5-FU and platinum in NPC treatment.

METHODSMedline, the Cochrane library, and the Chinese medical literature database were searched for eligible studies. Meta-analysis was performed using Review Manager (Version 5.2).

RESULTSSix random controlled trials (RCTs) including 514 patients met our criteria. Meta-analysis showed that the regimen of CCRT with taxanes and platinum had an improved significant difference in complete remission (CR) and less incidence rate in adverse reactions such as gastrointestinal impairment grades III-IV, liver and kidney impairment grades I-II, and radiodermatitis grades III-IV versus the conventional regimen of CCRT with 5-FU and platinum, while the longterm effectiveness rate of overall survival, locoregional failure-free survival, or distant metastasis failure-free survival between the two groups was therapeutic equivalence.

CONCLUSIONSThe regimen of CCRT with taxanes and platinum in NPC therapy may be more efficient and safe compared to the conventional modality of 5-FU and platinum in CCRT. However, we need more high-quality studies of multi-center and randomized double-blind clinical trials to further compare, analyze, and confirm the findings.
