Formation of cancer stem cells (CSCs) and increased cells proliferation are involved in tumorigenesis, tumour recurrence and therapy resistance and microRNA is essential for the development of the biological traits of CSCs and the increased cells proliferation. Studying molecular mechanism of tumorigenesis, tumour recurrence and therapy resistance of lung cancer will help us to further understand the pathogenesis and progression of the disease and offer new targets for effective therapies. In the present study, we found that miR-520a-3p expression is downregulated in NSCLC (non-small cell lung cancer) and SCLC (small cell lung cancer)...

BACKGROUND: Prophylactic cranial irradiation (PCI) is indicated for limited disease (LD) in small cell lung cancer (SCLC) patients who achieve a complete or near-complete response; however, it is sometimes not administered because of possible adverse reactions or patient refusal. Here we assessed treatment outcomes among patients with SCLC who were not treated with PCI. METHODS: The medical records of 60 patients (45 men, 15 women; mean age, 68 years; age range, 51-82 years) with SCLC were retrospectively reviewed...

BACKGROUND: Rapid on site examination (ROSE) is encouraged at endobronchial ultrasound transbronchial needles aspiration (EBUS-TBNA) to improve diagnostic yield. Due to new therapeutic options in lung cancer, it is not sufficient to merely distinguish between non-small cell lung carcinoma (NSCLC) and small cell lung carcinoma (SCLC). Immunohistochemistry (IHC) distinction is now standard practice, as well as additional molecular testing where clinically indicated. We investigated the diagnostic yield of on-site smears vs...

BACKGROUND: Progastrin-releasing peptide (proGRP) is a recently identified biomarker of small cell lung cancer (SCLC). We evaluated the usefulness of plasma proGRP level as a tumor marker for diagnosis and treatment monitoring in patients with SCLC. METHODS: Plasma samples were collected prospectively from 452 [212 non-small cell lung cancer (NSCLC), 105 SCLC, and 135 other diseases] patients who visited the hospital for tissue diagnosis. Plasma proGRP levels were measured using a two-step automated immunoassay...

Small cell-like change (SCLC) is a rare prostate lesion which has been described in only two previous studies (total of eight cases). Its relation to possible neuroendocrine differentiation remained unclear. We evaluated 11 SCLC cases with immunohistochemistry and electron microscopy. SCLC was characterized by crowded hyperchromatic small nuclei with scant cytoplasm, rosette-like structures, finely granular chromatin with indistinct nucleoli, and lack of mitoses, apoptoses, and necroses. In nine cases, SCLC was admixed with high-grade cancer, and in two cases, it represented a separate intraductal process, spatially remote from a low-volume Gleason score 6 (grade group 1) cancer...

OBJECTIVE: Although surgery in selected small-cell lung cancer (SCLC) patients has been proposed as a part of multimodality therapy, so far, the prognostic impact of node-spreading pattern has not been fully elucidated. To investigate this issue, a retrospective analysis was performed. METHODS: From 01/1996 to 12/2012, clinico-pathological, surgical, and oncological features were retrospectively reviewed in a multicentric cohort of 154 surgically treated SCLC patients...

Small cell lung cancer (SCLC) is a high-grade neuroendocrine tumor characterized by rapid growth, early metastatic spread, and initial responsiveness to therapy. Although the incidence of SCLC is declining, it remains one of the common causes of cancer-related mortality. Initial evaluation of patients with SCLC should focus on determining the extent of disease and the ability of the patient to tolerate specific therapy. Positron emission tomography (PET) can improve the accuracy of staging and treatment planning in many patients...

The treatment paradigm for lung cancer has been transformed in recent years by the use of immunotherapy, specifically, immune checkpoint antibodies (mAb), which are agents designed to reinvigorate an immune-mediated anticancer response by releasing the effects of tumor-mediated immunosuppression. Late-phase clinical trials of these agents in patients with advanced lung cancers have translated into improved clinical outcomes compared with standard-of-care chemotherapy for the treatment of metastatic non-small cell lung cancer, and have resulted in FDA approvals for two immune checkpoint mAbs in the second-line setting...

BACKGROUND: Small cell lung cancer (SCLC) is a common lung cancer which presents with extensive stage disease at time of diagnosis in two-thirds of patients. For treatment of advanced disease, traditional platinum doublet chemotherapy induces response rates up to 80% but with few durable responses. CPI-613 is a novel anti-cancer agent that selectively inhibits the altered form of mitochondrial energy metabolism in tumor cells. METHODS: We evaluated CPI-613 with a single-arm, open-label phase II study in patients with relapsed or refractory SCLC...

Autoantibodies against SCLC-associated neuronal antigen ELAVL4 (HuD) have been linked to smaller tumors and improved survival, but the antigenic epitope and mechanism of autoimmunity have never been solved. We report that recombinant human ELAVL4 protein incubated under physiological conditions acquires isoaspartylation, a type of immunogenic protein damage. Specifically, the N-terminal region of ELAVL4, previously implicated in SCLC-associated autoimmunity, undergoes isoaspartylation in vitro, is recognized by sera from anti-ELAVL4 positive SCLC patients and is highly immunogenic in subcutaneously injected mice and in vitro stimulated human lymphocytes...

BACKGROUND: The effect of heparin in improving cancer survival has gained increasing attention over the past decades. Several clinical trials have evaluated the role of heparin on survival outcome and its safety profile in lung cancer patients. Thus, we performed a systematic review and meta-analysis from the results of randomized controlled trials (RCTs) to assess the efficacy and safety of heparin in patients with lung cancer without indication for anticoagulants. METHODS: We searched PubMed, Embase, and The Cochrane Central Register of Controlled Trials databases for relevant studies...

XRCC1 is a scaffold protein that provides for interaction of DNA polymerase, DNA ligase and damaged DNA. Genotyping was done for the five non-synonymous and synonymous variants of XRCC1 i.e. XRCC1, Arg(194)Trp, Pro(206)Pro, Arg(280)His, Arg(399)Gln, Gln(632)Gln. Logistic regression analysis was used to analyze the association of XRCC1 with lung cancer, followed by data mining analysis which included both Multi-dimensionality reduction (MDR) and Classification and Regression tree (CART) analysis so as to find possible interaction between SNPs on XRCC1 gene...

BACKGROUND: Advanced lung cancer inflammation index (ALI, body mass index [BMI] x serum albumin/neutrophil-lymphocyte ratio [NLR]) has been shown to predict overall survival (OS) in small cell lung cancer (SCLC). CT enables skeletal muscle to be quantified, whereas BMI cannot accurately reflect body composition. The purpose was to evaluate prognostic value of modified ALI (mALI) using CT-determined L3 muscle index (L3MI, muscle area at L3/height2) beyond original ALI. METHODS: L3MIs were calculated using the CT images of 186 consecutive patients with SCLC taken at diagnosis, and mALI was defined as L3MI x serum albumin/NLR...

BACKGROUND: Small cell lung cancer (SCLC) commonly presents as hilar/mediastinal masses. In some occasions, conventional flexible bronchoscopy fails and a substantial amount of time is lost until establishing the diagnosis. OBJECTIVE: The aim of the study was to demonstrate the superiority of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) compared to conventional methods in establishing the diagnosis as an initial modality as well as to point out the saved time until the diagnosis...

The 70 kDa heat shock protein (Hsp70) is a highly conservative molecular chaperone, that has important role in cell integrity. Recently considerable amount of data are accumulating on the potential role of Hsp70 in carcinogenesis and tumor progression. Most papers are focusing on intracellular or membrane bound protein, however very limited data exist on serum Hsp70, that can also induce innate and adaptive immune response. Previously we have published data on the correlation between coloretal cancer progression and serum Hsp70 concentration...

BACKGROUND: The inflammatory response indexes, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), have prognostic value for a variety of cancers. However, their prognostic value for small-cell lung cancer (SCLC) has been rarely reported. In this study, we monitored changes of NLR and PLR along with the clinical outcomes in patients with limited-stage and extensive-stage SCLC who received standard treatments. MATERIALS AND METHODS: We retrospectively reviewed the records of 153 patients who were pathologically diagnosed with SCLC and collected their hematological data at different time points during disease and treatment process...

BACKGROUND: Concurrent chemoradiotherapy (CCRT) is the standard treatment for limited-stage small-cell lung cancer (LD-SCLC). However, the efficacy of consolidation chemotherapy (CCT) in LD-SCLC remains controversial despite several studies that were performed in the early years of CCT use. The aim of this study was to reevaluate the effectiveness and toxicities associated with CCT. METHODS: This retrospective analysis evaluated 177 patients with stage IIIA and IIIB small-cell lung cancer (SCLC) who underwent CCRT from January 2001 to December 2013 at Sun Yat-Sen University Cancer Center (SYSUCC)...
