Induction chemoradiotherapy plus surgery remains an option to study in IIIA(N2) and selected IIIB NSCLC. Here we report ten-year long-term survival of a prospective multicenter German-French phase-II trial with trimodality. ⋯ This regimen achieves substantial LTS. Interestingly, adenocarcinomas, older patients, unfavorable comorbidity scores, higher BMI and light smokers demonstrate poor long-term outcome even with aggressive trimodality. This dataset defines the rationale for our ongoing randomized trial with surgery after induction therapy in IIIA(N2)/selected IIIB (ESPATÜ).

Metastatic non-small cell lung carcinoma (NSCLC) generally carries a poor prognosis, and systemic therapy is the mainstay of treatment. However, extended survival has been reported in patients presenting with a limited number of metastases, termed oligometastatic disease. We retrospectively reviewed the outcomes of such patients treated at two centers. ⋯ Radical treatment of selected NSCLC patients presenting with 1-3 synchronous metastases can result in favorable 2-year survivals. Favorable outcomes were associated with intra-thoracic disease status: patients with small radiotherapy treatment volumes or resected disease had the best OS. Future prospective clinical trials, ideally randomized, should evaluate radical treatment strategies in such patients.

The aim was to determine if combined pemetrexed, cisplatin, and cetuximab was efficacious and safe as first-line treatment in advanced nonsquamous non-small cell lung cancer (NSCLC). ⋯ Pemetrexed, cisplatin, and cetuximab appeared efficacious and tolerable in advanced nonsquamous NSCLC patients. The TR outcomes are hypothesis-generating given the study's size and nonrandomized nature.

Deregulation of miRNAs expression levels has been detected in many human tumor types, and recent studies have demonstrated the critical roles of miRNAs in cancer pathogenesis. Numerous recent studies have shown that miRNAs are rapidly released from tissues into the circulation in many pathological conditions. The high relative stability of miRNAs in biofluids such as plasma and serum, and the ability of miRNA expression profiles to accurately classify discrete tissue types and disease states have positioned miRNAs as promising non-invasive new tumor biomarkers. ⋯ High expression of miR-21 was associated with DFI and OS both in NSCLC tissues (P = 0.022 and P = 0.037) and plasma (P = 0.045 and P = 0.065), respectively. Moreover, we report for the first time that low expression of miR-10a in NSCLC plasma samples was associated with worse DFI (P = 0.050) and high expression of miR-30e-5p was found to be associated with shorter OS (P = 0.048). In conclusion, circulating miR-21, miR-10a and miR-30e-5p in plasma should be further evaluated as potential non-invasive biomarkers in NSCLC.

The recent approval of crizotinib for the treatment of anaplastic lymphoma kinase (ALK)-rearranged advanced non-small cell lung cancer (NSCLC) in the US and other countries has provoked intense interest in ALK rearrangements as oncogenic drivers, and promises to revolutionise the way in which NSCLC is diagnosed and treated. Here, we review clinical data to date for the use of crizotinib to treat patients with advanced, ALK-positive NSCLC and consider issues surrounding the detection of ALK-positivity including the use of fluorescence in situ hybridisation and the other potential techniques available, and their suitability for ALK screening. We also discuss the emergence of resistance to crizotinib therapy and the range of other ALK inhibitors currently in development.
