Efficacy and safety of radiofrequency ablation for lung cancers: A systematic review and meta-analysis.

Objective: To evaluate the efficacy and safety of radiofrequency ablation(RFA) for patients with lung cancers using meta-analysis.

Methods And Materials: A literature search (PubMed, Embase, Web of science and China National Knowledge Infrastructure) was undertaken until August 2017 to identify sufficient studies evaluating the efficacy and safety of RFA. Pooled proportions of estimates were calculated by performing the random effect model, including technical success rate, recurrence rate, local tumor progression rate and complications.

Identification of genome variations in patients with lung adenocarcinoma using whole genome re‑sequencing.

Lung adenocarcinoma is one of the types of non‑small cell lung carcinoma, which tends to be treated with surgical therapy rather than radiation therapy. It occurs in smokers and non‑smokers, and is the most common form of lung cancer among non‑smokers and women. Gene rearrangements, including ALK, ROS1 and RET, and gene mutations, including epidermal growth factor receptor (EGFR), HER2, Kristen rat sarcoma viral oncogene homolog, BRAF, phosphoinositide‑3‑kinase, catalytic, α polypeptide and MET, have been identified in lung adenocarcinoma, which enable targeted therapy in lung adenocarcinoma, for example erlotinib, gefitinib and afatinib, which are EGFR inhibitors.

Identification of mutant genes with high-frequency, high-risk, and high-expression in lung adenocarcinoma.

Background: To identify mutant genes with high-frequency-risk-expression between lung adenocarcinoma and normal samples.

Methods: The ribonucleic acid RNA-Seq data GSE34914 and GSE37765 were downloaded from the Gene Expression Omnibus database, including 12 lung adenocarcinoma samples and six controls. All RNA-Seq reads were processed and the gene-expression level was calculated.

The association of SIPA1 gene polymorphisms with breast cancer risk: evidence from published studies.

Previous studies have focused on the association of signal-induced proliferation associated 1 gene (SIPA1) with carcinogenesis of many cancers, including breast cancer. It has been suggested that SIPA1 polymorphisms are associated with susceptibility to breast cancer. In the present study, we performed a meta-analysis to systematically summarize the possible association between SIPA1 and the risk for breast cancer.

Null genotype of GSTT1 contributes to esophageal cancer risk in Asian populations: evidence from a meta-analysis.

Background/aims: Glutathione S-transferase T1 (GSTT1), a phase-II enzyme, plays an important role in detoxification of carcinogen electrophiles. Many studies have investigated the association between GSTT1 polymorphism and esophageal cancer risk in Asian populations, but its actual impact is not clear owing to apparent inconsistencies among those studies. Thus, a meta-analysis was performed to explore the effect of GSTT1 polymorphism on the risk of developing esophageal cancer.
