After progression-free survival lasting 4 years, new metastatic lesions were found in the patient's right lung, and she was administered crizotinib for 20 months. Selleckchem Apatinib Due to a suspicious recurrence in the intracranial surgical margin area, as well as an unbearable gastrointestinal reaction to crizotinib, alectinib was later adopted. At the 7-month follow-up, positron emission tomography/computed tomography revealed a clinical complete response. This case of an NSCLC patient with EML4-ALK fusion variant 1 who exhibited an exceptional response to chemoradiotherapy and ALK inhibitors might broaden horizons in efforts to reveal the molecular mechanism of radiosensitivity in ALK-positive NSCLC and provide reference for further research regarding the optimal radiotherapy delivery dose and tyrosine kinase inhibitor selection.Anaplastic lymphoma kinase (ALK) rearrangement, one of the common oncogene rearrangements in the mutational history of lung adenocarcinoma, occurs in approximately 5% of non-small cell lung cancer (NSCLC) patients who could be effectively treated with ALK tyrosine kinase inhibitors (TKIs). The earlier phase III PROFILE 1014 study has shown that crizotinib, a first-generation ALK-TKI, significantly improved progression-free survival (PFS) compared with platinum-based chemotherapy in patients with previously untreated advanced ALK-positive NSCLC. Thus, clinicians must screen potential candidates for this driver alteration to guide ALK inhibitor therapy with a molecular testing platform capable of capturing all ALK fusions. Echinoderm microtubule-associated proteins, including the EML4 gene, are the most common ALK rearrangement partner. With the widespread use of the next-generation sequencing (NGS) techniques, which could approach enable the simultaneous screening of multiple genetic alterations, increasingly ALK rearrangement partners have been documented. However, the concurrent two ALK rearrangements within the same patient have rarely previously been reported. Here, we describe a novel CCNY-ALK (C1A20) and ATIC-ALK (A7A20), coexisting in the same case with poorly differentiated NSCLC and providing evidence of its sensitivity to ALK inhibitors. link2 The newly identified rearrangement partners can be added to the list of ALK rearrangements that occurred in ALK-positive NSCLC, as it could lead to prolonged disease control. Also, while different ALK rearrangement variants might bring differing clinical outcomes, we discuss the impact of the co-mutations of these two ALK rearrangements on the sensitivity to ALK inhibitors. However, the impact of co-mutations on the pathogenesis of NSCLC should be further studied to supply more theoretical insight that co-mutations present for personalized anti-cancer therapy.Radiotherapy, along with other loco-regional interventions, is conventionally utilized as a palliative approach to alleviate symptoms and mitigate oncological emergencies in advanced non-small cell lung cancer (NSCLC). Thanks to the ongoing improvement of medical treatments in the last decade, such as targeted therapy and immunotherapy, the survival of patients with advanced NSCLC has been considerably prolonged, making it feasible and clinically beneficial for radiotherapy to play a more active role in highly selected subpopulations. In this review, we will focus on the evolving roles of radiotherapy in advanced NSCLC. First of all, among patients who are initially unable to tolerate aggressive treatment due to severe symptoms caused by metastases and/or tumor emergencies, timely radiotherapy could significantly improve their performance status (PS) and general condition, thus giving them a chance for intensive treatment and prolonged survival. The efficacy, potential candidates, and optimal dose-fractionati highlighted in this review.Small cell lung cancer (SCLC) is one of the malignant cancers of lung tumors, and hyponatremia, defined as serum sodium concentration (Na+) lower than 135 mmol/L, is the most common complication of solid tumors, with an incidence of up to 18.9% and a negative impact on quality of life in SCLC. As a prognostic index of SCLC, timely monitoring and correcting of hyponatremia is of great clinical significance for prolonging the survival period of patients. In the explore of new drugs for small cell lung cancer, it is necessary to include hyponatremia as an evaluation index in clinical studies. As the occurrence of hyponatremia is sometimes unavoidable owing to SCLC specific neurological characteristics, early monitoring to detect the presence of hyponatremia and timely correction are helpful to improve the prognosis of patients. There are many predisposing factors for hyponatremia, including heterotopia of antidiuretic hormone (ADH), use of platinum-based chemotherapy drugs, and intracranial metastasis, among others. Patients with small cell lung cancer are usually asymptomatic in the early stage, while it is of great significance to find a suitable clinical index to judge whether it is a malignant inducement or not. link3 In the clinical setting, due to different electrolyte levels and therapeutic scheduling for the primary disease, an individualized plan is often made, mainly comprising water restriction, infusion, and medications. This review includes related clinical studies and describes the common symptoms and predisposing factors of hyponatremia in patients with SCLC, and their impact on quality of life and prognosis.
Lung cancer (LC) is the most common cancer worldwide. The prevalence of LC and rate of associated mortality are high and increasing faster in China than in Western countries. Non-small cell lung cancer (NSCLC) accounts for most LCs. This study aims to be the first large, multi-center, non-interventional retrospective study of treatment patterns (type/duration, number of lines, completion rate), real-world outcomes, and medical costs among Chinese patients with advanced/metastatic NSCLC (IIIb/IV) or extensive-stage small cell LC (ES-SCLC).

This study will enroll 8,800 patients (≥18 years, with a diagnosis of advanced/metastatic NSCLC made between 1 December 2013 to 30 November 2014) from 35 to 50 Chinese sites. Hospital information systems (HIS) and electronic medical records will be retrospectively reviewed, in adherence with regulatory and ethical requirements. Early-stage treatment (starting from 1 December 2010) of patients with recurrent disease or early disease progression will be examined. Data willr., 2018.
Radiation-induced lung injury (RILI) is a common complication of thoracic cancer radiation therapy. Currently, there is no effective treatment for RILI. RILI is associated with chronic inflammation, this injury is perpetuated by the stimulation of chemokines and proinflammatory cytokines. Recent studies have demonstrated that granulocyte-macrophage colony-stimulating factor (GM-CSF) plays a pivotal role in inflammation and fibrosis. This study aimed to investigate the protective effect of GM-CSF against the development of RILI in lung tissue.

First, a single fraction of radiation at a dose of 16 Gy was targeted at the entire thorax of wild-type (WT) C57BL/6 mice and GM-CSF
mice to induce RILI. Second, we detected the radioprotective effects of GM-CSF by measuring the inflammatory biomarkers and fibrosis alteration on radiated lung tissues. Furthermore, we investigated the potential mechanism of GM-CSF protective effects in RILI.

The GM-CSF
mice sustained more severe RILI than the WT mice. RILI was significantly alleviated by GM-CSF treatment. Intraperitoneally administered GM-CSF significantly inhibited inflammatory cytokine production and decreased epithelial-mesenchymal transition (EMT) in the RILI mouse model.

GM-CSF was shown to be an important modulator of RILI through regulating inflammatory cytokines, which provides a new strategy for the prevention and treatment of RILI.

Histologic transformation of non-small cell lung cancer (NSCLC) to small cell lung cancer (SCLC) is a rare mechanism of acquired resistance to epidermal growth factor receptor (
)-targeted tyrosine kinase inhibitors. However, the SCLC transformation has also been observed in non.

mutant NSCLC. In these cases, whether SCLC initially co-exists with NSCLC or originates from initial NSCLC remains to be determined.

Whole exome sequencing was performed on 10 samples from 5 patients with SCLC transformation from lung adenocarcinoma (LUAD), a main subtype of NSCLC. Somatic mutations and copy number variations (CNVs) were analyzed to explore the differences between initial LUAD and transformed SCLC, as well as the origin of transformed SCLC.

After SCLC transformation, the mutation spectrum changed, with decreased C>T and increased C>A. Compared with initial LUAD, the CNV burden of transformed SCLC was greatly increased (39.0
. 61.1, Wilcoxon P=0.4). The higher the CNV burden of LUAD, the shorter the time to SCLC transformation was observed to be; and the higher the CNV burden of transformed SCLC, the shorter the overall survival (OS) after transformation. Clonal evolution analysis showed different clonal components between initial LUAD and transformed SCLC.

The transformation of LUAD into SCLC may be promoted by CNV events rather than mutational events. CNV burden was associated with the time to SCLC transformation and with the OS of patients following SCLC transformation. Transformed SCLC did not evolve directly from the initial LUAD but branched off from LUAD before the time of initial diagnosis.

Circular RNAs (circRNAs) are known to participate in lung cancer. However, their role in spinal metastasis (SM) of lung adenocarcinoma remains elusive. In this study, we determined that hsa_circ_0006571 serves as a sponge for miR-138, which targets sirtuin 1 (Sirt1) in the development of SM.

A human circRNA microarray was performed to compare SM and lung adenocarcinoma samples. The expression of hsa_circ_0006571 and miR-138 was determined using quantitative polymerase chain reaction (qPCR)
and
. Cell proliferation was performed by Cell Counting Kit-8 (CCK-8) and apoptosis was analyzed by Annexin V/PI staining. RNA-pulldown and RNA immunoprecipitation (RIP) were used to analyze the interaction between hsa_circ_0006571. Tumor metastasis was determined through a xenograft experiment
.

Hsa_circ_0006571 was observed to be significantly upregulated in SM tissues through circRNA microarray and qPCR. We detected a lower expression of miR-138 in SM tissues compared with lung adenocarcinoma. Hsa_circ_0006571 silencing suppressed lung cancer cell proliferation and migration while promoting apoptosis. Hsa_circ_0006571 interacted with miR-138 to promote expression of Sirt1, leading to activation of epithelial-mesenchymal transition (EMT). Xenograft experiments showed that downregulation of hsa_circ_0006571 delayed the SM of lung adenocarcinoma cells via the miR-138-Sirt1 axis.

Hsa_circ_0006571 promoted tumor cell migration and invasion via the miR-138/Sirt1 pathway. Our observations indicate that circRNAs are possible novel therapeutic targets for SM of lung adenocarcinoma.
