We performed this analysis to reveal the association between six well-identified oncogenic driver mutations and clinical and pathological features in lung adenocarcinomas from smokers. It may have the potentiality to optimize existing treatment strategies and clinical trial design. ⋯ This study represents the first comprehensive and concurrent analysis of these six well-identified driver mutations in a large cohort of lung adenocarcinoma from East-Asian smokers. Our molecular data in conjunction with the clinical and pathological features indicated that prospective genotyping of lung adenocarcinomas from smokers for these genetic alterations could lead to rationally chosen targeted therapy in the overwhelming majority of cases.

Carboplatin dosing using the Calvert and Cockcroft-Gault formulae in patients with low serum creatinine levels is discussed controversially. We conducted a retrospective analysis applying the CKD-EPI formula and the alternate size descriptors adjusted body weight and predicted normal weight in the Cockcroft-Gault equation for calculating the carboplatin dose. ⋯ The results show that application of the alternate size descriptor adjusted body weight in the Cockcroft-Gault equation can improve dosing accuracy especially in overweight and obese patients with low serum creatinine levels.

This study seeks to clarify the modern prognostic significance of visceral pleura invasion (VPI) in Stage IB (T2aN0M0) non-small cell lung cancer (NSCLC) within the context of the 7th edition TNM classification using the data set from a recent prospective multicenter trial. ⋯ Stage IB patients with VPI and tumours>3 cm and ≤ 5 cm have significantly worse prognosis than those with 'T2a' tumours on the basis of VPI or tumour size alone. This finding would suggest upstaging these patients from the current IB status to Stage IIA.

Influence of histology and biomarkers on first-line treatment of advanced non-small cell lung cancer in routine care setting: baseline results of an observational study (FRAME).
FRAME is a prospective observational study of first-line treatments for advanced non-small cell lung cancer (NSCLC). This interim analysis examines the influence of histology and biomarkers on therapeutic decisions. Baseline characteristic, treatment, and diagnostic procedure data were collected on European patients with stage IIIB/IV NSCLC who were treated with any first-line platinum-based doublet, with or without targeted agents, in routine clinical practice. ⋯ In addition, IHC and predictive biomarkers were routinely assessed. Histology, performance status, and age were key factors influencing first-line treatment choice in the routine care of patients with advanced NSCLC.

In this study, we investigated visceral pleural invasion (VPI) as a poor prognostic factor in patients with non-small cell lung cancer (NSCLC) according to the 7th edition of the TNM classification. ⋯ We identified the presence of VPI as an independent poor prognostic factor in patients with NSCLC of ≤7 cm. Tumors 3.1-5cm with VPI should be upstaged to T2b tumors in the future in the TNM classification of the Union of International Cancer Control staging system. In addition, the surgical strategy involving more extensive lymph node dissection for patients with ≤3 cm/VPI tumors, especially ≤2 cm/VPI, is warranted owing to more frequent lymph node metastasis.
