Targeted therapies have substantially changed the management of non-small cell lung cancer (NSCLC) patients with driver oncogenes. Given the high frequency, EGFR and ALK aberrations were the first to be detected and paved the way for tyrosine kinase inhibitor (TKI) treatments. Other kinases such as ROS1 and more recently RET have emerged as promising targets, and ROS1 and RET TKIs are already available for precision medicine.We screened a large cohort of 713 Caucasian non-squamous NSCLC patients lacking EGFR/KRAS/BRAF/HER2/PI3KCA/ALK aberrations for ROS1 and RET rearrangements using fluorescence in situ hybridization to determine the frequency and clinicopathological characteristics of ROS1- and RET-positive patients...

Targeting protein for Xenopus kinesin-like protein 2 (TPX2) has been demonstrated to be associated with the tumorigenesis of many cancers. In the present study, we investigated the role and preliminary mechanism of TPX2 in the resistance of lung squamous carcinoma to radiation therapy. The results showed that SK-MES-1R and NCI-H226R cells were more resistant to X-ray irradiation than the parental cells (SK-MES-1 and NCI-H226). Moreover, TPX2 was upregulated in the radioresistant cells compared with the parental cells...

Immunotherapy, especially checkpoint inhibitors such as anti-PD1 and anti-PDL1 antibodies, has changed the standard of care and the prognosis of melanoma, but also more recently of lung cancer, renal cancer and Hodgkin lymphoma. Results of preliminary studies in head and neck squamous cell carcinoma (HNSCC) as well as in less frequent tumors of the region, such as nasopharyngeal carcinoma and high grade salivary gland carcinoma, are also promising. Indeed, in a recent phase 3 study, the PD1 inhibitor nivolumab has recently demonstrated a significant improvement in overall survival for platin-resistant recurrent and/or metastatic HNSCC...

<br />The 8p12-p11 locus is frequently amplified in squamous cell lung cancer (SQLC); the receptor tyrosine kinase fibroblast growth factor receptor 1 (FGFR1) being one of the most prominent targets of this amplification. Thus, small molecules inhibiting FGFRs have been employed to treat FGFR1-amplified SQLC. However, only about 11% of such FGFR1-amplified tumors respond to single agent FGFR inhibition and several tumors exhibited insufficient tumor shrinkage, compatible with the existence of drug-resistant tumor cells...

Human lung squamous cell carcinoma is a deadly cancer for which present therapeutic strategies are inadequate. And traditional chemotherapy results in severe systemic toxicity. Compounds from living organisms often exert a biological activity, triggering several targets, which may be useful for the improvement of novel pharmaceuticals. Aloe-emodin (AE), a well-known natural compound, is a primary component of anthraquinones in Aloe vera and exhibits anti-proliferative and apoptotic effects on various tumor cells...

Malignancy and tuberculosis are common causes of lymphocytic exudative pleural effusion. However, it is occasionally difficult to differentiate malignant pleural effusion from tuberculous pleural effusion. Vascular endothelial growth factor (VEGF) is a critical cytokine in the pathogenesis of malignant pleural effusion. Endocan is a dermatan sulfate proteoglycan that is secreted by endothelial cells. Importantly, endocan mediates the vascular growth-promoting action of VEGF. The aim of this study was to evaluate the diagnostic significance of VEGF and endocan in pleural effusion...

OBJECTIVES: Lung cancer typically starts as a near-spherical lesion, but as it grows it may acquire an irregular radiologic formation. RECIST is based on the assumption that tumors are spherical, and consequently, proportional changes of tumor volume and parallel changes in tumor diameter, and vice versa. Hence, a 30% decrease in diameter (2r) implies a 65% decrease of volume, and a 20% increase in diameter implies a 73% increase of volume. MATERIALS AND METHODS: We compared volumetric measurement based on multi-detector CT technology with calculated volume (CV) according to RECIST in a cohort of 43 patients with advanced, non-squamous cell type, lung cancer treated with a combination of platinum and pemetrexed...

OBJECTIVES: We hypothesize that selected genetic and/or epigenetic changes associated with advanced tumours may help identifying early non-small cell lung cancers (NSCLCs) that recur after resection. Among epigenetic changes, long interspersed nuclear element-1 (LINE-1) hypomethylation is seen early during carcinogenesis and may act in concert with genetic alterations to cancer progression. LINE-1 hypomethylation and gene mutations frequently involved in lung cancer, were analysed to evaluate their prognostic role in resected stage I NSCLC...

We report the case of a 62-year-old man treated with nivolumab as fourth-line therapy for stage IV squamous cell carcinoma of the lung. Because of the onset of nivolumab-induced pneumonitis after 2 doses, nivolumab was discontinued. After discontinuation, the tumor gradually continued to decrease in size without any additional treatment for lung cancer. The patient obtained a long-lasting shrinking of the tumor over 6 subsequent treatment-free months after only 2 administrations of nivolumab. This type of response has not been seen for conventional anticancer drug treatments for NSCLC, and we speculate that a small group of patients with NSCLC will obtain sufficient efficacy from a few doses of nivolumab...

Lung cancer is the leading cause of cancer-related death worldwide. The most common type, non-small cell lung cancer (NSCLC), is further divided into two main types, squamous cell and non-squamous cell (which includes adenocarcinoma). Nivolumab, a fully human IgG4 programmed death-1 immune checkpoint inhibitor antibody, has shown not only an overall survival advantage when compared to docetaxel, but also a relatively good side-effect profile among patients with previously treated advanced squamous and non-squamous NSCLC...

Programmed cell death-ligand 1 (PD-L1) expression is commonly observed in non-small cell lung cancer (NSCLC). The prognostic value of PD-L1 expression and the maximum standardized uptake value (SUVmax) on 18F-Fluorodeoxyglucose positron emission tomography (18FDG-PET) in surgical pulmonary squamous cell carcinoma(SCC)remains unclear. Furthermore, the correlation between the SUVmax and PD-L1 expression has not been assessed. Thus, the purpose of this study was to investigate the correlation between PD-L1 expression and the SUVmax on 18FDG-PET and to examine the prognostic significance of PD-L1 expression and the SUVmax in surgical pulmonary SCC...

BACKGROUND: The programmed death-1/programmed death-ligand-1 (PD-1/PD-L1) immune regulatory axis has emerged as a promising new target for cancer therapeutics, with lasting responses seen in the treatment of metastatic renal and lung carcinomas, as well as melanomas. As tumor surface expression of PD-L1 has been found to correlate with objective responses to anti-PD-L1 immunotherapies, we investigated the expression of PD-L1 in human cervical tumors and provide an adopted scoring system for the systematic evaluation of PD-L1 staining...

AIM: Due to the emerging experience in VATS (video assisted thoracic surgery) lobectomies, in some centers the so called "non-intubated" VATS lobectomies (NITS - non-intubated thoracic surgery) gained increased authority, during which endotracheal intubation and muscle relaxation of the patient is not carried out, thus surgery is being performed with the patient breathing spontaneously. The recent study deals with our initial experience gained during uniportal NITS VATS lobectomies. PATIENTS AND METHOD: Between 24...

Squamous cell lung cancers (SQCLC) account for 25% of all NSCLCs, yet the prognosis of these patients is poor and treatment options are limited. Amplified FGFR1 is one of the most common oncogenic events in SQCLCs, occurring in ~20% of cases. AZD4547 is a potent and selective FGFR1-3 inhibitor with anti-tumor activity in FGFR1 amplified SQCLC cell lines and patient-derived xenografts. <br /><br />Experimental Design: Based on these data, we performed a phase 1 study of AZD4547 in patients with previously treated stage IV FGFR1 amplified SQCLCs (NCT00979134)...

Solid organ transplant recipients have increased risk for developing keratinocyte cancers (KC), including cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), in part as a result of immunosuppressive medications administered to prevent graft rejection. In the general population, KC are associated with increased risks of subsequent malignancy, however, the risk in organ transplant populations has not been evaluated. We addressed this question by linking the U.S. Scientific Registry of Transplant Recipients, which includes data on KC occurrence, with 15 state cancer registries...

Programmed cell death-1 (PD-1) ligand inhibitors have gained popularity in the treatment of advanced non-small-cell lung cancer. The immune system is regulated by stimulatory and inhibitory signaling and aims to achieve the balance between activation and inhibition. Treatment with immune checkpoint inhibitors enhances immune response, but is also known to diminish immune tolerance and increase autoimmune toxicity. Here we present a case of a patient with advanced squamous cell lung cancer who developed type I diabetes and thyroiditis after treatment with PD-1 checkpoint inhibitor nivolumab...
