e18204 Background: In Colombia, lung cancer is the first cause of mortality. However, there is a large gap in terms of the information available regarding the characteristics and survival of these patients in the country. Methods: This is an observational, descriptive study of a cohort of patients with stage IV non-small cell lung carcinoma who initiated medical treatment at Fundación Santa Fe de Bogotá, a high complexity hospital. We analyzed clinical characteristics, oncogenic addiction expression, PDL1 expression, treatments, progression free survival (PFS), overall survival (OSm) and treatment related complications. Results: Twenty-six patients were included during the 3 years. The OSm for all the cohort was 19.6 months(m). In the group without PDL-1 expression and negative for oncogenic addiction that received treatment with chemotherapy the OSm was 16.9m and the PFS 9.6m. The OSm for the group with EGFR mutation that received target therapy was 24,7m and the PFS 13.11m. The patients with ALK rearrangement treated with target therapy had an OSm 17m and PFS 5m. The group with expression greater than 50% for PDL-1 that received only immunotherapy OSm was 9.5m and PFS 9m, and in the group with expression for PDL-1 between 1-49% the median OSm and PFS has not been reached. In relation with grade 3 toxicity, 7% of patients that received chemotherapy had kidney failure, 7% emesis and 15% hyporexia. Patients that received target therapy 9% had diarrhea and 9% hepatotoxicity. 9% of patients with bevacizumab presented bleeding and 8% of patients with immunotherapy had autoimmune colitis, in all these cases the medication was suspended. Hypothyroidism was the most frequent complication with the immunotherapy, and it was resolved with substitution therapy. Conclusions: Clinical characteristics and outcomes of this cohort were similar to other lung cancer patients series. Factors like cigarette, nutritional status and ECOG were no significant in the survival. 34,6% of patients had EGFR mutation and 7% had ALK rearrangements. Related to PDL1 we found 26% expresser patients. The highest OS and PFS was for the group with the EGFR mutation and for the group with PDL-1 expression between 1-49%.

Object. Lung carcinoma is the leading cause of death from cancer. More than 50% of those with small cell lung cancer develop a brain metastasis. Corticosteroid agents, radiotherapy, and resection have been the mainstays of treatment. Nonetheless, median survival for patients with small cell lung carcinoma metastasis is approximately 4 to 5 months after cranial irradiation. In this study the authors examine the efficacy of gamma knife surgery for treating recurrent small cell lung carcinoma metastases to the brain following tumor growth in patients who have previously undergone radiation therapy, and they evaluate factors affecting survival. Methods. A retrospective review of 27 patients (47 recurrent small cell lung cancer brain metastases) undergoing radiosurgery was performed. Clinical and radiographic data obtained during a 14-year treatment period were collected. Multivariate analysis was utilized to determine significant prognostic factors influencing survival. The overall median survival was 18 months after the diagnosis of brain metastases. In multivariate analysis, factors significantly affecting survival included: 1) tumor volume (p = 0.0042); 2) preoperative Karnofsky Performance Scale score (p = 0.0035); and 3) time between initial lung cancer diagnosis and development of brain metastasis (p = 0.0127). Postradiosurgical imaging of the brain metastases revealed that 62% decreased, 19% remained stable, and 19% eventually increased in size. One patient later underwent a craniotomy and tumor resection for a tumor refractory to radiosurgery and radiation therapy. In three patients new brain metastases were demonstrating on follow-up imaging. Conclusions. Stereotactic radiosurgery for recurrent small cell lung carcinoma metastases provided effective local tumor control in the majority of patients. Early detection of brain metastases, aggressive treatment of systemic disease, and a therapeutic strategy including radiosurgery can extend survival.

Lung cancer is one of the most prevalent and lethal forms of the disease accounting for almost 20 per cent of all deaths from cancer. It is therefore the leading cause of cancer death in men and second most fatal in women. There are between 1.5 and 2 million new cases of cancer globally every year. A similar number die from the disease annually. There are two forms of lung cancer – small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC). SCLC is the more aggressive form being faster growing and more metastatic, however it also responds more effectively to treatments such as chemotherapy. NSCLC is the more common form of the disease, accounting for 85 per cent of cases. They develop more slowly than SCLCs, however they are largely unresponsive to chemotherapy and require precise surgical removal. Both present a huge medical problem in terms of diagnosis and treatment. Due to its far higher prevalence, NSCLC is the most studied of the two forms. A chemotherapeutic treatment has been developed that targets the epidermal growth factor receptor (EGFR). EGFR is majorly upregulated in most cases and plays a key role in the tumour's growth and survival. The treatment blocks the receptor and is usually very effective in the first instances. However, it is typically unable to clear the cancer as a single nucleotide mutation is capable of rendering the inhibitor unable to act on the receptor. Therefore, the cancer returns and continues to develop. New treatments are also required. This is the work of Dr Motoi Ohba of the Advanced Cancer Translational Research Institute, Showa University, Japan. His work is aimed at both uncovering novel targets for cancer treatment and finding and developing molecules that could effectively manipulate these targets.

Lung cancer is the leading cause of cancer-related mortality worldwide. Approximately 80% of lung cancer cases are non–small cell lung carcinoma (NSCLC). However current diagnostic and therapeutic modalities against NSCLC are ineffective due to incomplete understanding of molecular pathogenesis of NSCLC. Emerging evidence shows that long non-coding RNAs (lncRNAs) can function as biomarkers for diagnosis and prognosis. LncRNAs can control transcription, translation, and protein function via diverse mechanisms although they lack the protein coding potential. LncRNAs have attracted intense investigations on their roles in cancer. Mounting evidence indicates that lncRNAs are promising biomarkers in diagnosis and prognosis for NSCLC, especially their presence in body fluids. Herein we will review recent advances in the research that explores the diagnostic and prognostic potentials of lncRNAs in NSCLC. We will also discuss emerging evidence that suggested lncRNAs as therapeutic targets in NSCLC.

Abstract Background: Lung cancer is a leading cause of cancer death around the world, while the Transthyretin (TTR) is a specific biomarkers for clinical diagnosis. However, its role in lung cancer remains to be unknown. Methods: In the present study, we made attempt to investigate effect of abnormal expression of TTR on Non-small-cell lung carcinoma (NSCLC) by overexpression or knockdown of TTR.To further investigate the mechanisms underlying the potential role of TTR in NSCLC, we searched and verified several signal pathways . In vivo experiments, to verify the effect of TTR overexpression on tumors.Results: We finded that up-regulated TTR obviously suppressed cell proliferation, migration, invasion and increased apoptosis.Significant suppression of phosphor-MAPK/ERK was observed in TTR-treated NSCLC cells, implying that TTR was important for cellular progress by regulating MAPK/ERK signaling pathway. In vivo experiment, overexpression of TTR promoted cell apoptosis and inhibited tumor growth. Conclusions: Overall, our results suggest that TTR has a potential anti-tumor effect in human NSCLC progression, which provides theoretical basis for the diagnosis and treatment of NSCLC.Above all, further understanding of TTR was useful for clinical care.

Cell Lung Carcinoma

Small cell lung cancer, whose essence is neuroendocrine tumors, makes up proximately 14–20% of all lung cancer circumstances. Compared to non-small cell lung cancer, its clinical manifestation seems more positive and has a tendency to disseminate earlier in the process of its natural past. About 10% of patients present with brain metastases at the time of provisional diagnosis and sometimes all along the course of their disease, there will be 40–50% of developed brain metastases in addition. Although metastases in the brain parenchyma are often found in patients with advanced lung cancer, periventricular metastases are rare. We report one case of diffuse subependymal periventricular metastases from small cell carcinoma of the lung.

Cell Lung Carcinoma

High-grade neuroendocrine lung malignancies (large-cell neuroendocrine cell carcinoma, LCNEC, and small-cell lung carcinoma, SCLC) are among the most deadly lung cancer conditions with no optimal clinical management. The biological relationships between SCLC and LCNEC are still largely unknown and a current matter of debate as growing molecular data reveal high heterogeneity with potential therapeutic consequences. Here we describe murine models of high-grade neuroendocrine lung carcinomas generated by the loss of 4 tumor suppressors. In an Rbl1-null background, deletion of Rb1, Pten, and Trp53 floxed alleles after Ad-CMVcre infection in a wide variety of lung epithelial cells produces LCNEC. Meanwhile, inactivation of these genes using Ad-K5cre in basal cells leads to the development of SCLC, thus differentially influencing the lung cancer type developed. So far, a defined model of LCNEC has not been reported. Molecular and transcriptomic analyses of both models revealed strong similarities to their human counterparts. In addition, a 68Ga-DOTATOC–based molecular-imaging method provides a tool for detection and monitoring the progression of the cancer. These data offer insight into the biology of SCLC and LCNEC, providing a useful framework for development of compounds and preclinical investigations in accurate immunocompetent models.

Eosinophil Counts

Immunocheckpoint inhibitor (ICI) therapy has provided significant clinical improvements in the treatment of several malignancies. The purpose of this report is to increase awareness of hypereosinophilia associated with checkpoint inhibitors, a topic that has been rarely reported. Hypereosinophilia may need to be addressed especially if eosinophil counts increase to levels where hypereosinophilic visceral complications can occur. We are presenting a case of a 57-year-old male with hypereosinophilia that was seen in the setting of progression of metastatic non-small-cell lung cancer during and after nivolumab treatment.
