Therapeutic effects of adenovirus-mediated CD and NIS expression combined with NaI/5-FC on human thyroid cancer.

Thyroid cancer is the most common type of malignant endocrine tumor diagnosed. Previous studies have indicated that gene therapy is the most promising and effective therapeutic method for thyroid cancer. Therefore, in the present study, NaI/5-fluorocytosine (5-FC) treatment was combined with cytosine deaminase (CD, encoded by the gene) and sodium iodide symporter (NIS, encoded by the gene) to act together as a therapeutic tool for thyroid cancer.

Expression and clinical significance of STIP1 in papillary thyroid carcinoma.

The aim of this study was to detect stress-induced phosphoprotein 1 (STIP1) expression in papillary thyroid carcinoma (PTC) and to analyze its association with prognosis of PTC patients. Immunohistochemistry was performed to detect the expression of STIP1 in 113 PTC tissues and paired adjacent noncancerous tissues. The χ2 test was used to analyze the relationship between STIP1 expression and clinicopathological characteristics.

High expression of FOXC1 is associated with poor clinical outcome in non-small cell lung cancer patients.

The aim of this study was to detect FOXC1 expression in human non-small cell lung cancer (NSCLC) and to analyze its association with prognosis of NSCLC patients. Expressional levels of FOXC1 mRNA and protein in 30 cases of NSCLC and corresponding non-tumor tissue samples were examined by quantitative real-time PCR and Western blotting. Immunohistochemistry was performed to detect the expression of FOXC1 in 125 NSCLC tissues.

[The application of 18F-fluorodeoxyglucose positron emission tomography in the diagnosis and staging of lung cancer].

Objective: To study the clinical value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) in the diagnosis and staging of lung cancer.

Methods: Ninety-four patients with lung nodular changes were examined by CT, 18F-FDG PET and pathology, cytology. 18F-FDG PET images were analyzed by semi-quantitative standard uptake value (SUV) only and (or) SUV plus visual observation.
