Stereotactic body radiotherapy (SBRT) is an alternative to surgery for patients with early stage non-small cell lung cancer (NSCLC) who are inoperable due to comorbid disease or who refuse surgery. SBRT results in an excellent local control rate of more than 90%, which is comparable to surgery, while short and long-term overall toxicity is low. Surgically treated patients are often more extensively staged pre-operatively, e.g. with endobronchial ultrasound and/or mediastinoscopy, and typically undergo intra-operative lymph node dissection or sampling...

INTRODUCTION: Patients referred to tertiary cancer centers often present with imaging studies performed and interpreted at other health care institutions. Although reinterpretation of imaging performed at another health care institution can reduce repeat imaging, unnecessary radiation dose, and cost, the benefit is uncertain. The purpose of this study is to evaluate the quality of initial imaging studies of patients seeking a second opinion at a tertiary cancer center, to compare the accuracy of initial interpretations to reinterpretations performed by subspecialty trained radiologists at a tertiary oncologic center, and to determine the potential impact on patient management...

BACKGROUND: Skeletal muscle loss, commonly known as sarcopenia, is highly prevalent in older adults and linked with adverse outcomes in cancer, yet the definition and role of sarcopenia remains uncertain. The aim of this study was to examine the association of Computerized Tomography (CT) assessed skeletal muscle measures with physical function in older adults with cancer. RESULTS: CTs for 185 patients were available. Median age 73 (IQR 68-76) and 56.5% female. After controlling for sex and BMI, we found no evidence that SMI was associated with physical function impairments...

This study was performed with the aim to investigate the correlations of tumor necrosis factor-alpha (TNF-α) gene promoter polymorphisms with the risk of thymoma-associated myasthenia gravis (T-MG) in a northern Chinese Han population. Between June 2005 and June 2015, 305 MG patients (150 males and 155 females, MG group) and 293 healthy volunteers (negative control (NC) group) were enrolled in this study. Among the MG patients, there were 121 patients with thymoma-associated MG (T-MG group) and 184 without T-MG (NT-MG group)...

Hepatocellular carcinoma (HCC) is the fifth leading cause of cancer mortality worldwide. Several studies have investigated the relationship between (18)F-fluorodeoxyglucose ((18)F-FDG) uptake on positron emission tomography and the prognosis of patients with HCC, although the relationship between (18)F-FDG uptake and expression of EMT-related proteins in these patients remains unclear. We retrospectively enrolled 116 patients with HCC treated by curative surgical resection and who underwent (18)F-FDG positron emission tomography/computed tomography (PET/CT) for preoperative staging...

BACKGROUND: Locally advanced non-small cell lung cancer (LA-NSCLC) patients have poorer survival and local control with mediastinal node (N2) tumor involvement at resection. Earlier assessment of nodal burden could inform clinical decision-making prior to surgery. This study evaluated the association between clinical outcomes and lymph node volume before and after neoadjuvant therapy. MATERIALS AND METHODS: CT imaging of patients with operable LA-NSCLC treated with chemoradiation and surgical resection was assessed...

Oral squamous cell carcinoma (OSCC) is a common malignancy that has been causally associated with both hereditary and acquired factors. The high mobility group box 1 (HMGB1) gene plays an important role as a DNA chaperone to help maintain nuclear homeostasis. Altered expression of HMGB1 has been implicated in a wide range of pathological processes, including inflammation and cancer. The present study explores the impact of HMGB1 gene polymorphisms, combined with environmental risks regarding susceptibility to oral tumorigenesis...

We aimed to identify STK31 as a cancer-testis (CT) gene and to explore its potential clinical value, regulatory mechanisms, and gene network in pancreatic cancer (PC). Gene expression data were generated from normal organ samples and pancreatic cancer samples from three public databases. STK31 expression patterns in normal and PC tissues were identified, and we explored its regulatory mechanisms. Gene ontology (GO) and pathway analyses of STK31-related genes were performed and an STK31 protein-protein interaction (PPI) network was constructed...

PURPOSE: To determine whether the addition of standardized uptake value (SUV) from PET scans to CT lung texture features could improve a radiomics-based model of radiation pneumonitis (RP) diagnosis in patients undergoing radiotherapy. METHODS AND MATERIALS: Anonymized data from 96 esophageal cancer patients (18 RP-positive cases of Grade ≥ 2) were collected including pre-therapy PET/CT scans, pre-/post-therapy diagnostic CT scans and RP status. Twenty texture features (first-order, fractal, Laws' filter and gray-level co-occurrence matrix) were calculated from diagnostic CT scans and compared in anatomically matched regions of the lung...

Importance: Asymptomatic microscopic hematuria (AMH) is highly prevalent and may signal occult genitourinary (GU) malignant abnormality. Common diagnostic approaches differ in their costs and effectiveness in detecting cancer. Given the low prevalence of GU malignant abnormality among patients with AMH, it is important to quantify the cost implications of detecting cancer for each approach. Objective: To estimate the effectiveness, costs, and incremental cost per cancer detected (ICCD) for 4 common diagnostic approaches evaluating AMH...

Telomerase activation via induction of the catalytic component telomerase reverse transcriptase (TERT) plays essential roles in malignant transformation. TERT promoter-activating mutations were recently identified as a novel mechanism to activate telomerase in hepatocellular carcinoma (HCC) and many other malignancies. In addition, single nucleotide polymorphisms (SNPs) in the TERT rs2736098 and rs2736100 are significantly associated with cancer susceptibility. It is currently unclear whether different germline TERT variants modify TERT promoter mutations...

The tumor suppressor role of AT-rich interactive domain containing protein 1B (ARID1B) has drawn much attention in area of cancer etiology. However, it had remained unknown whether or not genetic variants of ARID1B involved in development of hepatocellular carcinoma (HCC). In this study, three putatively functional variants in ARID1B (rs73013281C>T, rs167007A>G, and rs9397984C>T) were selected using bioinformatics tools, and a case-control study of 611 cases and 614 controls was conducted to investigate genetic associations with HCC risk in a Southern Chinese population...
