Abstract
BACKGROUND To investigate the efficacy and safety of apatinib alone or apatinib plus paclitaxel/docetaxel versus paclitaxel/docetaxel in the treatment of advanced non-small cell lung cancer (NSCLC) through pooling of open published data. METHODS The electronic databases of Medline (1960-2021.5), Cochrane central register of controlled trials (CENTRAL), EMBASE(1980-2021.5) and Wan fang (1986-2021.5) were systematically searched by two reviewers to identify the relevant clinical trials related to the above subject. The objective response rate (ORR), disease control rate (DCR) and drug relevant adverse reactions were pooled and demonstrated by risk ratio (RR) and 95% confidence interval (95% CI). The statistical heterogeneity across studies was assessed by I-square test. The publication bias was evaluated by Egger's line regression test and demonstrated by Begg's funnel plot. RESULTS Eleven prospective studies were included in the meta-analysis. The pooled results indicated that the ORR (RR = 1.62, 95% CI: 1.32-2.00, p < 0.05) and DCR (RR = 1.29, 95% CI: 1.18-1.41, p < 0.05) of apatinib alone or apatinib plus paclitaxel/docetaxel was significantly higher than that of the paclitaxel/docetaxel group for advanced NSCLC, respectively. The drug-related adverse reaction was not statistically different between apatinib alone or apatinib plus paclitaxel/docetaxel with regard to the hand-foot syndrome, gastrointestinal reaction, thrombocytopenia, anemia and leukocytopenia (pall > 0.05) except for hypertension (RR = 3.60, 95% CI: 1.26-10.31, p < 0.05). Subgroup analysis also indicated that the hypertension and hand-foot syndrome in apatinib + paclitaxel/docetaxel were higher than that of the paclitaxel/docetaxel group with a statistical difference (p < 0.05). CONCLUSIONS Apatinib alone or apatinib plus paclitaxel/docetaxel was superior to paclitaxel/docetaxel for ORR and DCR. However, combined treatment with apatinib appears to increase the risk of a patient developing an adverse reaction, especially hypertension and hand-foot syndrome.

Abstract
Curcumin, a yellow pigment derived from Curcuma longa Linn, has attracted great interest in the research of cancer during the past decades. Extensive studies documented that curcumin attenuates cancer cell proliferation and promotes apoptosis in vivo and in vitro. Curcumin has been demonstrated to interact with multiple molecules and signal pathways, which makes it a potential adjuvant anti-cancer agent to chemotherapy. Previous investigations focus on the mechanisms of action for curcumin, which is shown to manipulate transcription factors and induce apoptosis in various kinds of human cancer. Apart from transcription factors and apoptosis, emerging studies shed light on latent targets of curcumin against epidermal growth factor receptor (EGFR), microRNAs (miRNA), autophagy and cancer stem cell. The present review predominantly discusses significance of EGFR, miRNA, autophagy and cancer stem cell in lung cancer therapy. Curcumin as a natural phytochemicals could communicate with these novel targets and show synergism to chemotherapy. Additionally, curcumin is well tolerated in humans. Therefore, EGFR-, miRNA-, autophagy- and cancer stem cell-based therapy in the presence of curcumin might be promising mechanisms and targets in the therapeutic strategy of lung cancer.

Abstract
BACKGROUND AND OBJECTIVE The relapse-free time of gefitinib as the second or third line therapy in patients with advanced non-small cell lung cancer (NSCLC) was not satisfactory. The aim of this study is to evaluate the efficacy and toxicity of pemetrexed in patients with pulmonary adenocarcinoma after failure to chemotherapy and gefitinib. METHODS A total of 32 relapsed patients with pulmonary adenocarcinoma after failure to chemotherapy and gefitinib received pemetrexed 500 mg/m2 by the intravenous administration on the first day, with 21 days as a cycle. Dexamethasone, folic acid and vitamin B12 were applied to relieve the drug toxicity. The objective response rate was estimated by Response Evaluation Criteria in Solid Tumors (RECIST) and the toxicity was estimated by National Cancer Institute Common Toxicity Criteria (version 3.0). RESULTS For a total of 32 patients, 4 patients reached partial response (PR), constituting a total of 12.5%; 11 patients reached stable disease (SD), constituting a total of 34.4%; 17 patients reached progressive disease (PD), constituting a total of 53.1%. The median progression free survival (PFS) was 2.7 months. The median overall survival (OS) was 11.0 months. One-year survival rate was 37.5%. The most common adverse events (AEs) were myelosuppression with grade I and grade II toxicity. Other adverse events were tolerated. CONCLUSION Pemetrexed was clinically beneficial for the patients with pulmonary adenocarcinoma after the failure of chemotherapy and gefitinib.
