For patients with hepatocellular carcinoma and cirrhosis, the rupture of thin lymphatic vessel walls leads to a profuse outflow of lymph fluid. Typically, chyloperitoneum tends to precede the development of chylothorax in patients with cancer. The present study describes the case of a male patient with hepatocellular carcinoma who developed chylothorax without chyloperitoneum.

Small-cell lung cancer (SCLC) is a highly metastatic and recalcitrant malignancy. Metastasis is the major cause of death in patients with SCLC but its mechanism remains poorly understood. An imbalance of hyaluronan catabolism in the extracellular matrix accelerates malignant progression in solid cancers due to the accumulation of low-molecular-weight HA.

Objective: Lung adenocarcinoma (LUAD) is the most common type of lung cancer. However, predictive biomarkers for early efficacy and prognosis evaluation in patients with surgically resected LUAD are not completely explained.
Methods: Differentially expressed genes (DEGs), gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were identified by RNA sequencing (RNA-Seq) between thirteen LUAD tissues and five normal lung tissues.
Objectives: The newly released eighth edition of the American Joint Committee on Cancer TNM staging system for lung cancer seeks to improve prognostic accuracy but lacks external validation for small cell lung cancer (SCLC). Moreover, previous studies posed a few questions concerning survival differences for patients with specific site N3 node involvement or single-site metastasis (SSM) in different distant organs. The aim of this study was to validate the eighth edition of the TNM classification for SCLC in an independent multi-institutional cohort from China and answer the questions raised by the previous research.

Chest wall tumors are a relatively uncommon disease in clinical practice. Most of the published studies about chest wall tumors are usually single-center retrospective studies, involving few patients. Therefore, evidences regarding clinical conclusions about chest wall tumors are lacking, and some controversial issues have still to be agreed upon.

Methods: A total of 120 patients diagnosed as non-small cell lung cancer (NSCLC) and received radical resection of lung cancer surgery for the first time were randomized into a conventional nursing group, a rehabilitation training group and a TEAS group, 40 cases in each group. Conventional nursing was adopted in the conventional nursing group.
Purpose: Lung adenocarcinoma (LUAD) accounts for approximately half of patients in lung cancer. Cancer-associated fibroblasts (CAFs) are the major component in the tumor microenvironment (TME). Targeting CAFs is a promising therapeutic strategy for cancer treatment.

However, the molecular driven factors have not been elucidated. Recently, a novel hydrolase called cell migration inducing hyaluronidase (CEMIP) triggered both migration and invasion in many tumors but not SCLC.

Persistent activation of NRF2 associates with poor prognosis across different cancer types. However, the beneficial therapeutic strategy to harness this pathway in cancer remains unclear.

Here, we investigated the role of connexin 43 (Cx43) and its derived GJIC in the interplay between non-small cell lung cancer (NSCLC) cells and cancer-associated fibroblasts (CAFs).
Methods: CAFs and NSCLC cells were co-cultured with direct contact and separated using flow cytometry.
NUT carcinoma (NC) is an aggressive squamous tumor characterized by NUT gene rearrangement, and the most common fusion form is BRD4-NUT. However, NC diagnosis is difficult for its rareness and often being confused with a variety of poorly differentiated tumors. A 21-year-old Chinese woman was referred to our hospital for cough and intermittent fever.

The SP and non-SP (NSP) cells in A549 cells were isolated and their differentiation was analyzed by fluorescence-activated cell sorting. An plate clone assay, Matrigel Transwell assay and chemoresistance analysis of the sorted SP and NSP cells were performed.

Methods: The liposomes were investigated for size, zeta-potential, lipid content, antibody binding ability, and pcDNA loading capacity. The ability of immunoliposomes to target tumor-derived endothelial cells and perform gene transfer in vitro was measured and their basic biocompatibility was evaluated.
An association between epidermal growth factor receptor (EGFR) and clinical characteristics of non-small cell lung cancer (NSCLC) was reported ten years ago. In addition, a different type of relationship was seen in different ethic races. However, the relationship between these factors is not well understood in the Guangxi province.

Firstly, ERCC1 gene was successfully transfected into H1299 cells by gene cloning and transfection techniques. Then, cell proliferation was determined with the cell growth curve and colony-forming assays.

Objective: To isolate and characterize the side population cells (SP cells) in the lung adenocarcinomas cell line A549.
Methods: The protein expression of ABCG2 in human lung adenocarcinoma cell line A549 was detected by immunohistochemistry. SP and NSP cells in the cell line A549 were isolated by FACS, and their differentiation was analysed.
Objective: To evaluate the relationship between combined multigene detection and response to adjuvant chemotherapy and prognosis in early-stage non-small cell lung cancer (NSCLC).
Methods: Tissue microarray was prepared from samples of 86 cases of early-stage NSCLC who received adjuvant chemotherapy after radical surgery. The expressions of caspase-3, Fas, bax, bcl-2, survivin, PCNA, Ki67, MGMT, p53, p63, p73, p16, p27, VEGF, nm23, P-gp, MRP, LRP, GST-pi, Topo II, c-myc, cyclin-D1, Her-2, Cox-2, Ku70, Ku80, DNA-PKcs, ERCC1, MSH2, BCRP proteins were detected using immunohistochemical two-step method.
