ALK -rearranged lung cancer defines a distinctive molecular cohort of patients whose outcomes are significantly improved by the availability of ALK inhibitors. Thus, it is imperative for clinicians to screen appropriate patients for this driver mutation with a molecular testing platform capable of capturing all ALK fusions. Here, we report a novel VKORC1L1-ALK fusion and an ALK T1151K resistance mutation detected in a lung cancer patient who had been on crizotinib for over 8 years. Alectinib induced a dramatic response in this patient demonstrating its clinical activity against T1151K...

"Silica" refers to crystalline particles formed by the combination of silicon with oxygen. Inhalation of silica particles promotes the development of pulmonary fibrosis that over prolonged periods increases the risk of lung cancer. The International Agency for Research on Cancer (IARC) classified crystalline silica as a human carcinogen in 1997. This categorization was questioned due to 1) the absence of dose-response findings, 2) the presence of confounding variables that complicated interpretation of the data and 3) potential selection bias for compensated silicosis...

Introduction: Histologic transformation from non-small cell lung cancer (NSCLC) to small cell lung cancer (SCLC) is a well-recognized mechanism of resistance in EGFR -mutant adenocarcinoma upon treatment with TKIs, but rarely reported with programmed death1 (PD-1) inhibitors. We report two cases of potential transformation during treatment with PD-1 inhibitors. Case presentations: Case 1, a 65-year-old man was diagnosed with stage IVa lung adenocarcinoma on pleural fluid cytology...

Purpose: To report the outcomes of stereotactic body radiation therapy (SBRT) for stage I non-small-cell lung cancer (NSCLC) according to respiratory motion management method. Methods: Patients with stage I NSCLC who received SBRT from 2007 to 2015 were reviewed. Computed tomography (CT) simulation with four-dimensional CT was performed for respiratory motion assessment. Tumor motion >1 cm in the craniocaudal direction was selectively treated with advanced respiratory management: either respiratory gating to a pre-specified portion of the respiratory cycle or dynamic tracking of an implanted fiducial marker...

Over 10% of small-cell lung cancer (SCLC) patients have brain metastases (BM) at initial diagnosis; more than 50% will develop BM within 2 years. BM are detected in up to 80% of all patients at autopsy. After primary treatment, prophylactic cranial irradiation (PCI) has been established as standard of care in SCLC patients responding to initial therapy. Based on level I evidence, PCI significantly decreases the risk of intracranial relapse and shows a modest survival benefit after 3 years. However, the role of PCI in defined patient subgroups such as resected SCLC, elderly and extensive stage patients with access to magnetic resonance imaging surveillance and stereotactic radiotherapy is yet to be fully clarified...

Objectives: Concurrent chemoradiotherapy is considered a standard option for patients with stage 3 small cell lung carcinoma. A 25% risk of acute esophagitis is experienced by patients as a result of the volume of esophagus encompassed within a conformal radiotherapy technique. We reviewed our institutional experience administering the radioprotectant amifostine prior to daily radiotherapy to determine its effects on the onset of esophagitis. Materials and methods: From 2005 to 2016, 49 patients diagnosed with stage 3 small cell lung carcinoma received concurrent chemoradiotherapy...

Alectinib can cause rare, but severe hypersensitivity. The cross-reactivity between different ALK inhibitors is unknown and desensitization is the only reported management. We hereby report the first case of severe delayed hypersensitivity developed in a lung cancer patient treated by alectinib, who was successfully managed by switching to brigatinib, another ALK inhibitor. The patient achieved excellent anti-tumor response to brigatinib. Our case provides an alternative and safe strategy in patients with alectinib-related hypersensitivity...

Background: Lobectomy has traditionally been recommended for fit patients diagnosed with early-stage non-small-cell lung cancer (NSCLC). Recently, however, stereotactic body radiotherapy (SBRT) has been introduced as an alternative treatment option. The purpose of this investigation is to compare survival outcomes for individuals with stage I/II NSCLC treated with lobectomy vs SBRT. Methods: This retrospective study included 191 patients (100 surgery, 91 SBRT) identified through the Lung Cancer Evaluation Center, Stony Brook, NY, between 2008 and 2012...

Fetal adenocarcinoma of the lung (FLAC) is a rare tumor. It accounts for ~0.1%-0.5% of all pulmonary neoplasms. Due to its rarity, much of the world literature regarding FLAC comes from case reports and case series. FLAC is an adenocarcinoma resembling developing fetal lung in its pseudoglandular stage (8-16 weeks of gestation). It is distinguishable from pulmonary blastoma (PB) because it lacks the mesenchymal component which is a hallmark finding in PB. Due to differences in histopathology and clinical course, FLAC has been further categorized into low-grade (L-FLAC) and high-grade (H-FLAC) forms...

In non-small-cell lung cancer (NSCLC) refractory to standard therapy and which lacks well-known oncogenic drivers, genomic profiling can still identify genomic alterations that may suggest potential sensitivity to targeted therapy. PTEN mutation in NSCLC may be sensitizing to analogs of rapamycin such as everolimus or temsirolimus, but more investigation is needed. We report the case of a patient with metastatic NSCLC harboring a PTEN mutation as well as high tumor mutational burden and PD-L1 positivity with a durable response to temsirolimus, but refractory to a checkpoint inhibitor...

GLI1 is a transcriptional regulator involved in the development of different types of cancer. GLI1 transcriptional activity is regulated within the Hedgehog pathway (canonical activity), but can also be controlled independently (non-canonical activity) in the context of other signaling pathways. Experimental evidences show GLI1 involvement in both small- and non-small-cell lung cancers. Direct inhibition of the protein, in combination with other chemotherapeutic agents, represents a promising strategy for the treatment of different malignancies...

Stereotactic body radiation therapy (SBRT) has emerged as a new technology in radiotherapy delivery, allowing for potentially curative treatment in many patients previously felt not to be candidates for radical surgical resection of stage I non-small-cell lung cancer (NSCLC). Several studies have demonstrated very high local control rates using SBRT, and more recent data have suggested overall survival may approach that of surgery in operable patients. However, SBRT is not without unique toxicities, and the balance of toxicity, and effect on patient-reported quality of life need to be considered with respect to oncologic outcomes...

Plasma cell-free tumor DNA, or circulating tumor DNA (ctDNA), from liquid biopsy is a potential source of tumor genetic material, in the absence of tissue biopsy, for EGFR testing. Our validation study reiterates the clinical utility of ctDNA next generation sequencing (NGS) for EGFR mutation testing in non-small cell lung cancer (NSCLC). A total of 163 NSCLC cases were included in the validation, of which 132 patients had paired tissue biopsy and ctDNA. We chose to validate ctDNA using deep sequencing with custom designed bioinformatics methods that could detect somatic mutations at allele frequencies as low as 0...

Non-small-cell lung cancer (NSCLC) represents about 85% of all lung cancers, and more than half of NSCLCs are diagnosed at an advanced stage. Chemotherapy has reached a plateau in the overall survival curve of about 10 months. Therefore, in last decade novel targeted approaches have been developed to extend survival of these patients, including antiangiogenic treatment. Vascular endothelial growth factor (VEGF) signaling pathway plays a dominant role in stimulating angiogenesis, which is the main process promoting tumor growth and metastasis...

Background: Various biomarkers have been shown to predict prognosis in various types of cancers. However, these biomarkers have not been studied in advanced small cell lung cancer (SCLC). The modified Glasgow prognostic score (mGPS) is based on serum albumin level and C-reactive protein (CRP). The prognostic nutritional index (PNI) is a combination of serum albumin level and absolute lymphocyte count. This study aimed to evaluate the prognostic value of mGPS and PNI in SCLC. Methods: We retrospectively reviewed and calculated mGPS and PNI for patients with stage IIIB or IV SCLC who initiated platinum-based combination chemotherapy between November 2007 and June 2016...

Acquired resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) is a universal event and limits clinical efficacy. The third-generation EGFR inhibitor osimertinib is active in EGFR-mutant/T790M positive non-small-cell lung cancer. Mechanisms of acquired resistance are emerging, and here we describe a cis-oriented solvent-front EGFR G796S mutation as the resistance mechanism observed in a progression biopsy and circulating tumor DNA (ctDNA) from a patient with initial response followed by progression on osimertinib...

Lung cancer belongs to malignant tumors that possess the highest rates of morbidity and mortality in the world. A number of morphological, biological and clinical features justify the distinction of small-cell carcinoma with respect to the other histological types of lung cancer. The predominant neuroendocrine phenotype is critical for the selection of biomarkers used in diagnostics, monitoring and evaluation of treatment response; early onset relapses in patients with small-cell lung cancer (SCLC) and the evaluation of their prognosis...

Background: Longitudinal data on the impact of treatment on quality of life (QoL) in advanced non-small cell lung cancer (NSCLC) are limited. In this palliative setting, treatment that does not deteriorate QoL is key. Here we report longitudinal QoL in patients with squamous NSCLC, receiving ≤4 cycles of nab -paclitaxel/carboplatin combination chemotherapy. Methods: Patients received nab -paclitaxel 100 mg/m2 days 1, 8, 15 + carboplatin area under the curve 6 mg•min/mL day 1 (q3w) for four cycles...
