Objective:This study was aimed to research the feasibility of ATP-bioluminescence assay(ATP-TCA) guiding the treatment on recurrent non-small cell lung cancer(NSCLC) combined with malignant pleural effusion.Methods:We collected 30 pleural fluid samples which were approved to be positive by cytology from recurrent NSCLC patients.These cells were cocultured with chemotherapy medicines,single agent or drugs combination.Five drug concentrations,two parallel holes were examined in vitro for 4 days,the results were measured by adding luciferase-fluorescein working system and luminescence analyzer.We applied chemotherapy medicines according to the results in vitro of ATP-TCA.Results:There were differences among drug sensitivities of individuals.All the samples could be evaluated.Effective single drugs included cisplatinum,mitomycin C,doxorubicin,and pemetrexed disodium;sensitive drugs in the combination therapy were gemcitabine plus cisplatin,vinorelbine plus cisplatin,paclitaxel plus cisplatin,docetaxel plus cisplatin,and mitomycin C,vindesine plus cisplatin,in which gemcitabine + cisplatin(GEM + DDP) in vitro was the most efficient program.Conclusion:ATP-TCA in vitro sensitivity assay is rapid,reliable,and simple to guide the treatment of recurrent NSCLC with malignant pleural effusion,and can help clinicians to make the individual chemotherapy program. 展开更多
