“…During the last decade, the development of molecular targeted drugs has increased the effectiveness of NSCLC therapy ( 5 ). Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), including gefitinib, erlotinib and icotinib, have been demonstrated to be effective for the treatment of advanced NSCLC with few adverse effects, particularly in patients with NSCLC harboring EGFR mutations ( 5 , 6 ). A multi-institutional randomized phase II trial demonstrated that gefitinib had effective clinical antitumor activity and provided symptomatic relief in patients with NSCLC ( 7 ).…”

The present network meta-analysis aimed to compare the effectiveness and adverse effects of gefitinib, erlotinib and icotinib in the treatment of patients with non-small cell lung cancer (NSCLC). Two reviewers searched the Cochrane, PubMed, Embase, ScienceDirect, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals and Wanfang databases for relevant studies. Studies were then screened and evaluated, and data was extracted. End-points evaluated for NSCLC included complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), overall response rate (ORR), disease control rate (DCR), progression-free survival (PFS), median survival time (MST) and adverse effects, including rash, diarrhea, nausea and vomiting, fatigue and abnormal liver function. For the analysis of incorporated studies, RevMan, SPSS, R and Stata software were used. A total of 43 studies with 7,168 patients were included in the network meta-analysis. No significant differences were observed in CR, PR, SD, PD, ORR or DCR between gefitinib, erlotinib and icotinib by using network meta analysis. Compared with gefitinib, erlotinib resulted in a higher rate of nausea and vomiting [adjusted odds ratio (OR)=2.0; 95% credible interval, 1.1–3.7]. However, no significant differences were observed in the rates of rash, diarrhea, fatigue or abnormal liver function using network meta-analysis. Compared with erlotinib, gefitinib resulted in a lower SD rate [OR=0.86; 95% confidence interval (CI): 0.75–0.99; P=0.04], and lower rates of rash (OR=0.45; 95% CI, 0.36–0.55; P<0.00001), diarrhea (OR=0.75; 95% CI, 0.61–0.92; P=0.005), nausea and vomiting (OR=0.47; 95% CI, 0.27–0.84; P=0.01) and fatigue (OR=0.43; 95% CI, 0.24–0.76; P=0.004) through meta-analysis of two congruent drugs. However, gefitinib resulted in a higher rate of rash compared with icotinib (OR=1.57; 95% CI, 1.18–2.09; P=0.002). Otherwise, no significant differences were observed in CR, PR, PD, ORR, DCR and abnormal liver function between gefitinib, erlotinib and icotinib through meta-analysis of two congruent drugs. The PFS rate for gefitinib, erlotinib and icotinib was 5.48, 5.15 and 5.81 months, respectively. The MST was 13.26, 13.52, 12.58 months for gefitinib, erlotinib and icotinib, respectively. Gefitinib and icotinib resulted in significantly higher PFS rates compared with erlotinib (P<0.05). Erlotinib resulted in a significantly longer MST compared with gefitinib and icotinib (P<0.05). In conclusion, gefitinib, erlotinib and icotinib had similar effectiveness for the treatment of patients with advanced NSCLC. However, gefitinib resulted in a lower frequency of fatigue, and nausea and vomiting, compared with the other two drugs. Icotinib resulted in a lower frequency of rash. Erlotinib resulted in a longer MST, but was also associated with a higher frequency of rash, and nausea and vomiting.

Hyperglycaemia Induced by Novel Anticancer Agents: An Undesirable Complication or a Potential Therapeutic Opportunity?

Signalling pathways involving protein kinase, insulin-like growth factor 1, insulin receptors and the phosphoinositide 3 kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) system are critical in promoting oncogenesis. The use of anticancer agents that inhibit these pathways frequently results in hyperglycaemia, an on-target effect of these drugs. Hyperglycaemia induced by these agents denotes optimal inhibition of the desired pharmacological target. As hyperglycaemia can be treated successfully and effectively with metformin, managing this complication by reducing the dose of or discontinuing the anticancer drug may be counterproductive, especially if it is otherwise effective and clinically tolerated. The use of metformin to treat hyperglycaemia induced by anticancer drugs provides a valuable therapeutic opportunity of potentiating their clinical anticancer effects. Although evidence from randomised controlled trials is awaited, extensive preclinical evidence and clinical observational studies suggest that metformin has anticancer properties that improve overall survival in patients with diabetes and a variety of cancers. Metformin has also been reported to reverse resistance to epidermal growth factor receptor (EGFR)-inhibiting tyrosine kinase inhibitors. This review summarises briefly the role of the above signalling pathways in oncogenesis, the causal association between inhibition of these pathways and hyperglycaemia, and the effect of metformin on clinical outcomes resulting from its anticancer properties. The evidence reviewed herein, albeit almost exclusively from observational studies, provides support for a greater use of metformin not only in patients with cancer and diabetes or drug-induced hyperglycaemia but also potentially as an anticancer drug. However, prospective randomised controlled studies are needed in all these settings to better assess the effect on clinical outcomes of adding metformin to ongoing anticancer therapy.

Background:We aimed to evaluate whether EGFR mutations (mEGFR) and KRAS amino acid substitutions can predict first site of recurrence or metastasis after non-small-cell lung cancer (NSCLC) surgery.Methods:Data were reviewed from 481 patients who underwent thoracic surgery for NSCLC between 2007 and 2012.Results:Patients with KRAS G12C developed significantly more bone metastases compared with the remainder of the cohort (59% vs 16%, P<0.0001). This was confirmed in multivariate analysis (MA) (odds ratio (OR): 0.113 (95% confidence interval (CI): 0.055–0.231), P<0.0001). Significantly, more patients with mEGFR developed liver and brain metastases compared with the remainder of the cohort (30% vs 10%, P=0.006; 59% vs 1%, P<0.0001, respectively). These were confirmed in MA (OR: 0.333 (95% CI: 0.095–0.998), P=0.05; OR: 0.032 (95% CI: 0.008–0.135), P<0.0001, respectively). Patients with KRAS G12V developed significantly more pleuro-pericardial metastases compared with the remainder of the cohort (94% vs 12%, P<0.0001). This was confirmed in MA (OR: 0.007 (95% CI: 0.001–0.031), P<0.0001). Wild-type patients developed significantly more lung metastases (35% vs 10%, P<0.0001). This was confirmed in MA (OR: 0.383 (95% CI: 0.193–0.762), P=0.006).Conclusion:Epidermal growth factor receptor mutation and KRAS amino acid substitutions seem to predict site-specific recurrence and metastasis after NSCLC surgery.
