BACKGROUND/AIM: The purpose of this trial was to evaluate the feasibility and efficacy of alternating platinum-based doublet chemotherapy with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in patients with EGFR-mutant non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemotherapy-naive patients with advanced NSCLC harboring an EGFR mutation were enrolled. All patients underwent induction chemotherapy by sequentially alternating pemetrexed/cisplatin/bevacizumab and EGFR-TKIs followed by maintenance therapy with pemetrexed/bevacizumab and EGFR-TKIs. The primary outcome was the completion rate of the induction therapy. RESULTS: Eighteen eligible patients were enrolled between May 2011 and March 2016. The completion rate of induction therapy was 72.2% (13/18). Unfortunately, one patient developed grade 4 acute renal injury, but no other serious complications concerning this protocol were observed. Furthermore, diarrhea, rashes, and hematological adverse effects were mild. CONCLUSION: The completion rate of induction therapy was promising. Alternating chemotherapy and EGFR-TKIs should be further investigated regarding feasibility and efficacy.

BACKGROUND: Since it can take an enormous amount of time and cost to discriminate counterfeit medicines by using conventional methods, counterfeit medicines has been spread in the world markets. OBJECTIVE: The purpose of this study was to develop a rapid and simple analytical method to discriminate counterfeit drugs using near infrared (NIR) spectroscopy. METHODS: Seven types of brand name tablet and generic tablets containing atorvastatin calcium sesquihydrate (AT) preparations were used as simulated counterfeit medicines. NIR spectra of 35 AT tablet products were measured using a diffuse reflection method. RESULTS: The NIR spectral data were analyzed by principal component analysis (PCA). The PCA results suggested that the model had sufficient accuracy to discriminate the 7 types for AT tablets. The NIR spectral data were also analyzed using a soft independent modeling of class analogy (SIMCA) method. Predicting the classification of the AT tablet samples was performed based on all the validated AT tablet data using the SIMCA model, and the probability of classification of 7 types was 100%. The discrimination power spectrum of the SIMCA model indicated significant patterns based on diluents. CONCLUSIONS: The PCA and SIMCA classification of the AT tablets were depended on the major excipient combinations.
