The cost of new anti-cancer drugs has dramatically increased in recent years, and countermeasures are required in order to limit pharmaceutical expenses. Sponsored clinical trials that provide drugs free of charge may be a useful tool in order to reduce drug costs. The aim of this analysis is to evaluate the effect of clinical trials on pharmaceutical expenditure savings. ⋯ The participation in sponsored clinical trials in which drugs are provided free of charge offers substantial cost savings for the National Health Service; moreover, the grants received for each enrolled patient produced additional income.

Endobronchial ultrasound (EBUS) can be used as an alternative to fluoroscopy to visualize a peripheral pulmonary lesion (PPL) and to provide an image guidance for transbronchial biopsy (TBB). The aim of this study was to verify the accuracy of EBUS-guided TBB in the diagnosis of PPLs. ⋯ These data obtained from a large series of patients and using an original method show that EBUS represents a valid support to bronchoscopy and that the EBUS-guided TBB has a high diagnostic yield in the diagnosis of PPLs.

A 55-year-old Caucasian woman with lung adenocarcinoma stage IV presented with repeated relapse after treatment with cytotoxic chemotherapy (carboplatin, gemcitabine, docetaxel, pemetrexed) and targeted agents (erlotinib, cetuximab, sunitinib). Comprehensive molecular diagnostics (EGFR-, ALK-, RAS-, BRAF-, PIK3CA-, HER2- and DDR2-aberrations) were performed and failed initially to detect any driver mutation. ⋯ The patient was subsequently treated with crizotinib and experienced a pronounced clinical improvement corresponding to a complete metabolic response in (18)F-FDG-PET and a good and confirmed partial response in CT (RECIST 1.1). Our case exemplifies the need for rapid implementation of newly discovered rare genetic lung cancer subtypes in routine molecular diagnostics.

Squamous cell carcinoma (SQCC) of the lung is the second-largest subtype of non-small cell lung cancer (NSCLC), causing an estimated 400,000 deaths per year worldwide. Recent developments in cancer genome sequencing technology expanded our knowledge of driver mutations, which were identified as novel candidates for targeted therapy in various cancers. Successful targeted treatments for lung adenocarcinoma, NSCLC's primary subtype, with EGFR mutation or ALK fusion are clinically available, and a clinical trial of personalized targeted therapy in patients with lung adenocarcinoma is underway by the Lung Cancer Mutation Consortium. ⋯ The march toward personalized therapy may have taken a step forward with the discovery of these potential biomarkers for the treatment of SQCC of the lung. This article reviewed the current knowledge of genomic landscape of lung SQCC and summarized ongoing clinical trials of targeted agents for lung SQCC. Also, we will suggest several other actionable mutations with matching drugs that should be investigated in future clinical trials for the personalized treatment of lung SQCC.

Tumor-associated macrophages (TAMs) can be abundantly present in numerous cancer types. Under influence of various stimuli in the tumor microenvironment TAMs develop into a tumor-inhibitory (M1) or tumor-promoting (M2) phenotype. ⋯ In this review we will discuss the importance of TAMs in the pathogenesis and clinical outcome of lung cancer and mesothelioma patients. In addition, the potential of TAMs as therapeutic targets will be discussed.
