Mechanism of Xu Li's Experiential Prescription for the Treatment of EGFR-Positive NSCLC.

ABSTRACT: The non-small-cell lung cancer (NSCLC) is the most common lung cancer which seriously threatens the human health. Xu Li's experiential prescription (XLEP) can treat the NSCLC. However, whether XLEP can regulate the autophagy in the EGFR-positive NSCLC still remains unknown. We found that the cellular activity of drug-resistant cells and sensitive cells were all decreased in the TCM group and TCM?+?Gef group. The expression of autophagy-associated proteins (mTOR and Beclin1-Vps34) in drug-resistant cells was decreased in the TCM group, while the expression of autophagy-associated proteins in sensitive cells was all decreased in the TCM?+?Gef group. The ratio of M1/M2 macrophages was increased when IL-4-induced RAW264.7 was treated with TCM. TCM treatment promoted the expression of CCL2 and CCL3 while it downregulated the CCL22 level among A549, H1975, and PC9 cells. The expression of TNF-? and IL-6 was increased, and the expression of IL-10 and TGF-? was decreased in IL-4-induced RAW264.7 cells treated with TCM. And, TCM treatment also decreased the expression of Fizz1 and TGM2. In conclusion, this study indicated that XLEP could suppress the proliferation of EGFR-TKI-resistant cancer cells and increase the ratio of M1/M2 macrophages by inhibiting autophagy to treat the drug-resistant EGFR-positive NSCLC.

The non-small-cell lung cancer (NSCLC) is the most common lung cancer which seriously threatens the human health. Xu Li's experiential prescription (XLEP) can treat the NSCLC. However, whether XLEP can regulate the autophagy in the EGFR-positive NSCLC still remains unknown.

Project description:Background: ALK inhibitors have shown positive advance in the treatment of ALK+ NSCLC. They have achieved better results in prolonging the progression free survival and improving quality of life in comparison to chemotherapy. We have assembled the evidence related to the efficacy and safety of these agents in the treatment of ALK positive NSCLC. Materials and Methods: A comprehensive search was conducted using electronic databases of PubMed, Medline and Cochrane Library to identify the studies involving comparison of ALK inhibitors to chemotherapy and Next generation ALK inhibitors to crizotinib. PFS was the primary outcome while other outcomes like ORR, adverse events, quality of life and OS were also analyzed and compared. Hazard ratios and odds ratios obtained were analyzed using fixed effect or random effects model in Review Manager Software. Results: A total of 12 studies (n = 3,297) met the criteria for inclusion in this review and meta-analysis. ALK inhibitors including crizotinib, ceritinib and alectinib revealed significantly better PFS (HR 0.42 [0.35, 0.50; p < 0.00001]), ORR (Overall OR 6.59 [4.86, 8.94; p < 0.00001] as compared to chemotherapy in the first line as well as second line treatment settings. Intracranial response rate was better with ALK inhibitors (ceritinib and alectinib) as compared to chemotherapy OR 6.51 [2.86, 14.83; p < 0.00001]. No significant increase in grade 3 or 4 adverse events was observed with crizotinib (OR 1.21 [0.82, 1.77; p = 0.34]) or ceritinib (OR 1.49 [0.86, 2.57; p = 0.17]) when compared to chemotherapy individually. Quality of life indicators assessed were significantly improved with ALK inhibitors. Next generation agents (ceritinib, alectinib and brigatinib) revealed significant improvement in PFS (HR 0.50 [0.43, 0.57; p < 0.00001]), ORR (OR 1.57 [1.21, 2.04; p = 0.0006]) in comparison to crizotinib. Next generation agents (Alectinib and brigatinib) yielded better response intra-cranially than crizotinib in terms of objective response rate (OR 5.87 [3.49, 9.87; p < 0.00001]) and time to CNS progression (HR 0.25 [0.13, 0.46; p < 0.0001]). Alectinib by far resulted in fewer adverse events than chemotherapy or crizotinib. Conclusions: Overall ALK inhibitors are safe and effective treatment option in ALK+ non-small cell lung cancer. Of the ALK inhibitors, Next generation agents in particular alectinib and brigatinib are safer and more effective intra-cranially and can be preferred as first option.
