PURPOSE The overall survival (OS) results in patients with ALK-positive metastatic non–small-cell lung cancer (NSCLC) have rarely been reported. The aim of this prospective-retrospective cohort study was to obtain real-world data on the use of crizotinib or chemotherapy in patients with ALK-positive metastatic NSCLC in Russia. PATIENTS AND METHODS Patients with epidermal growth factor receptor–negative metastatic NSCLC were screened in 23 cancer centers. To be eligible, patients were required to have confirmation of ALK rearrangement. Patients were treated with crizotinib (250 mg twice daily; n = 96) or the investigator’s choice of platinum-based chemotherapy (n = 53). The primary end point was OS. RESULTS A total of 149 ALK-positive patients were included. Mean age was 53 years in both groups. Patients were predominately women (59%) and never-smokers (74%), and most patients had adenocarcinoma histology (95%). At a median follow-up time of 15 months, 79 of the 149 patients included in the analysis had died. Median OS from the start of treatment was 31 months (95% CI, 28.5 to 33.5 months) in the crizotinib group and 15.0 months (95% CI, 9.0 to 21.0 months) in the chemotherapy group ( P < .001). The objective response rate was 34% in the crizotinib group. Among patients with brain metastasis, one complete response (6%) and five partial responses (31%) were achieved. Grade 3 adverse events were observed in three patients (3%) in the crizotinib group. CONCLUSION The improved OS observed in crizotinib clinical trials in ALK-positive NSCLC was also observed in the less selective patient populations treated in daily practice in Russia. The use of standard chemotherapy in these patients remains common but seems inappropriate as a result of the effectiveness of newer treatments, such as crizotinib.

AbstractPlatinum-based chemotherapy remains the cornerstone of treatment for most non-small cell lung cancer (NSCLC) cases either as maintenance therapy or in combination with immunotherapy. However, resistance remains a primary issue. Our findings point to the possibility of exploiting levels of cell division cycle associated protein-3 (CDCA3) to improve response of NSCLC tumours to therapy. We demonstrate that in patients and in vitro analyses, CDCA3 levels correlate with measures of genome instability and platinum sensitivity, whereby CDCA3high tumours are sensitive to cisplatin and carboplatin. In NSCLC, CDCA3 protein levels are regulated by the ubiquitin ligase APC/C and cofactor Cdh1. Here, we identified that the degradation of CDCA3 is modulated by activity of casein kinase 2 (CK2) which promotes an interaction between CDCA3 and Cdh1. Supporting this, pharmacological inhibition of CK2 with CX-4945 disrupts CDCA3 degradation, elevating CDCA3 levels and increasing sensitivity to platinum agents. We propose that combining CK2 inhibitors with platinum-based chemotherapy could enhance platinum efficacy in CDCA3low NSCLC tumours and benefit patients.

Platinum Based Chemotherapy

Caspase 8 is a protein involved in the process of cell apoptosis, which may affect the efficacy of anti-cancer treatment. The aim of our study was to determine the impact of polymorphisms in the CASP-8 gene encoding caspase 8 on the prognosis in non-small-cell lung cancer (NSCLC). The study involved 99 patients with newly diagnosed locally advanced or metastatic NSCLC treated with platinum-based chemotherapy. The presence of the GG genotype was associated with distant metastases, smoking, and a family history of cancer. The higher risk of early progression was associated with weight loss and the CASP-8 genotype (GG vs. AG or AA: 20.51% vs. 2.86%). The higher risk of progression-free survival (PFS) shortening was associated with a higher stage of disease (hazard ratio (HR) = 2.50, 95% CI: 1.61–3.89, p < 0.0001), distant metastases (HR = 2.30, 95% CI: 1.42–3.72, p = 0.0016), and the GG genotype (HR = 1.68, 95% CI: 1.10–2.57, p = 0.0152). The influence of the GG genotype on the PFS was confirmed in a multivariate analysis (HR = 1.80, 95% CI: 1.06–3.05, p = 0.0317). We did not confirm the influence of CASP-8 genotypes on the overall survival (OS).
