Influence of pleural invasion on survival in pathologic T3-4N0M0 non-small cell lung cancer: a propensity score matching study based on the Surveillance, Epidemiology, and End Results database.

Background: Pleural invasion (PI) is considered to be an adverse prognostic factor in non-small cell lung cancer (NSCLC). However, the prognostic roles of PI in pathologic (p)T3-4N0M0 NSCLC remain controversial. Therefore, this study aimed to evaluate the predictive value of PI in patients with pT3-4N0M0 NSCLC.

Long Noncoding RNA GAS5 Suppresses Tumorigenesis by Inhibiting miR-23a Expression in Non-Small Cell Lung Cancer.

Previous studies reported that elevated expression of long noncoding RNA (lncRNA) GAS5 led to the arrest of non-small cell lung cancer (NSCLC) cell growth and a promotion of apoptosis both in vitro and in vivo. However, its underlying molecular mechanism in NSCLC is still unclear. In the present study, we noted that GAS5 was downregulated in NSCLC tissues and cells and was negatively correlated with miR-23a expression.

NFAT1 promotes cell motility through MMP-3 in esophageal squamous cell carcinoma.

Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors and the prognosis of patients remains poor. Increasing evidence suggests that nuclear factor of activated T cell (NFAT1) plays an important role in the development and progression of cancers. Herein, we show that NFAT1 was overexpressed in human ESCC, which was significantly associated with advanced tumor stage and lymph node metastasis.

[Expression of PTEN, matrix metaloproteinases 2 and 9 in thymomas].

Objective: To evaluate the expression of PTEN, MMP-2 and MMP-9 in thymomas and their correlation with clinical significance.

Methods: Immunohistochemical S-P assay was used to detect the expression of PTEN, MMP-2 and MMP-9 in 45 thymomas and 16 non-neoplastic thymuses.

Results: The positive rate of PTEN, MMP-2 and MMP-9 expression in 45 thymomas were 53.
