INTRODUCTION: Preclinical studies suggest that angiotensin system inhibitors (ASI) and bevacizumab improve tumor perfusion and chemotherapy efficacy. We performed a retrospective study to examine whether concomitant ASI use during carboplatin and paclitaxel (CP) without or with bevacizumab (CPB) was associated with improved overall survival (OS) in patients with advanced nonsquamous, non-small-cell lung cancer (NS-NSCLC). PATIENTS AND METHODS: In a retrospective cohort study, adult patients diagnosed with stage IIIB or IV NS-NSCLC between 2005 and 2011 were identified from tumor registries at 1 of 4 Kaiser Permanente regions...

INTRODUCTION: First-line epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor treatment of advanced non-small-cell lung cancer with EGFR-activating mutations improves outcomes compared with chemotherapy, but resistance develops in most patients. Compensatory signaling through type 1 insulin-like growth factor 1 receptor (IGF-1R) may contribute to resistance; dual blockade of IGF-1R and EGFR may improve outcomes. PATIENTS AND METHODS: We performed a randomized, double-blind, placebo-controlled phase II study of linsitinib, a dual IGF-1R and insulin receptor tyrosine kinase inhibitor, plus erlotinib versus placebo plus erlotinib in chemotherapy-naive patients with EGFR-mutation positive, advanced non-small-cell lung cancer...

BACKGROUND: The optimal timing of thoracic radiation therapy (RT) in relation to chemotherapy is unknown in the treatment of nonmetastatic small cell lung cancer (SCLC). We analyzed the National Cancer Data Base (NCDB) to assess the effect on overall survival (OS) of RT timing with chemotherapy for patients with SCLC. MATERIALS AND METHODS: The NCDB was queried for patients diagnosed with nonmetastatic SCLC from 1998 to 2011 who had undergone definitive chemoradiation...

BACKGROUND: After stereotactic body radiotherapy (SBRT) to the lung, radiation pneumonitis and fibrotic changes often develop, and the tumor shadow usually becomes indistinguishable from the fibrotic shadow. Occasionally, however, a residual mass in patients with no or mild radiation pneumonitis will be observed on serial computed tomography (CT) scans. The purpose of the present study was to evaluate the fate of such residual masses and, if possible, to determine the types of tumor at increased risk of local recurrence...

Small-cell lung cancer (SCLC) is distinguished from non-small-cell lung cancer by its rapid growth and more frequent metastases. Although patients with SCLC are highly responsive to chemotherapy and radiation therapy, long-term prognosis remains poor, with relapse and disease recurrence occurring in almost all cases. Whereas combination chemotherapies continue to be the standard of care in extensive-stage SCLC, there is value in exploring whether immune-checkpoint inhibition is an effective treatment strategy, given the durable responses in non-small-cell lung cancer...

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) as first-line therapy for patients with EGFR-mutated non-small-cell lung cancer (NSCLC) have shown a significantly better objective response rate and progression-free survival than platinum doublet therapy. However, acquired resistance often occurs within 12 months. One of the potential strategies for treating acquired resistance in NSCLC is the readministration of EGFR-TKIs, a strategy that has mainly been evaluated using gefitinib or erlotinib...

BACKGROUND: Adjuvant chemotherapy (ACT) improved survival in the NCIC Clinical Trials Group JBR.10 trial of resected stage IB/II non-small-cell lung cancer. A prognostic 15-gene expression signature was developed, which may also predict for benefit from ACT. An exploratory economic analysis was conducted to assess the potential cost-effectiveness of using the 15-gene signature in guiding ACT decisions. METHODS: A decision analytic model was populated by study patients with quantitative reverse transcription polymerase chain reaction tumor profiling, current costs, and quality-adjusted survival...

The treatment outcome has been unsatisfactory for patients with non-small-cell lung cancer (NSCLC) refractory to standard first-line chemotherapy. Trastuzumab emtansine (T-DM1), an anti-HER2 antibody conjugated with a vinca alkaloid, has been approved for clinical use in HER2+ breast cancer in many countries. Approximately 5% of NSCLC tumors possess HER2 alterations, and T-DM1 has shown excellent antitumor effects against HER2+ lung cancer cell lines in preclinical models. Therefore, we hypothesized that T-DM1 could significantly inhibit the growth of HER2+ lung cancers...

BACKGROUND: Patients with limited metastases, oligometastases (OMs), might have improved outcomes compared with patients with widespread distant metastases (DMs). The incidence and behavior of OMs from non-small-cell lung cancer (NSCLC) need further characterization. PATIENTS AND METHODS: The medical records of patients who had undergone surgery for stage I-III NSCLC from 1995 to 2009 were retrospectively reviewed. All information pertaining to development of the first metastatic progression was recorded and analyzed...

INTRODUCTION: Chemoresistance is a major challenge in the treatment of advanced non-small-cell lung cancer (NSCLC). Because the Sonic hedgehog (Shh) pathway is reactivated in NSCLC, we investigated an association between chemoresistance and Shh activation. PATIENTS AND METHODS: From a cohort of 178 patients with advanced NSCLC treated with platinum-based chemotherapy as first-line treatment, we selected all surgical tumor samples at diagnosis (n = 36). Shh activation was evaluated through Gli1 and Gli2 expression using immunohistochemistry (quantitative score)...

BACKGROUND: The immune system has important roles in tumor development and outcomes after cancer treatment. We evaluated whether single-nucleotide polymorphisms (SNPs) in the gene encoding casitas B-lineage lymphoma b protein (Cbl-b), an E3 ubiquitin ligase that maintains immune tolerance by negatively regulating T-cell activation and function, were associated with outcomes after treatment of non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Samples from 393 patients with NSCLC treated with definitive radiotherapy at a single institution between March 1998 and February 2009 were used to genotype 3 potentially functional SNPs in CBLB (rs1042852 C>T, rs2305035 G>A, and rs7649466 C>G)...

BACKGROUND: The efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in squamous cell carcinoma (SCC) of the lung remains controversial, and the role of EGFR testing in patients with SCC of the lung remains debatable. PATIENTS AND METHODS: We retrospectively identified patients with stage IIIB or IV SCC of the lung who had undergone EGFR testing at Shanghai Chest Hospital from January 2009 to December 2013. RESULTS: A total of 29 EGFR mutation-positive patients (22 patients had received TKI therapy and 7 had not) and 151 EGFR wild-type patients (27 patients had received TKI therapy and 124 had not) were available for an analysis of efficacy...

BACKGROUND: The median age at diagnosis of lung cancer is 70 years. However, the evidence guiding the management of octogenarians and older patients with non-small-cell lung cancer (NSCLC), is based on data derived from younger patients and may not be appropriate. METHODS: Patients ≥ 80 years diagnosed with clinical stages I and II NSCLC, between 1988 and 2007, were identified from the SEER database. Patients were classified according to treatments received: no treatment, surgery only, radiation only, and surgery + radiation...
