Apoptosis promoted by up-regulation of TFPT (TCF3 fusion partner) appears p53 independent, cell type restricted and cell density influenced.

The TFPT/FB1 gene was identified because of its involvement in childhood pre-B acute lymphoblastic leukaemia (ALL). Although its specific function is still unclear, Tfpt has been implicated in cell proliferation and induction of programmed cell death (PCD). Given the critical role of PCD in leukemogenesis, we have investigated the responsiveness of different cell lines to TFPT over expression and the consequent induction of PCD by proliferation kinetic analysis, immunolocalization and TUNEL assay.

Early-stage hepatocellular carcinoma in patients with cirrhosis: long-term results of percutaneous image-guided radiofrequency ablation.

Purpose: To perform a prospective, intention-to-treat clinical trial to determine the long-term survival rates of patients with hepatic cirrhosis and early-stage hepatocellular carcinoma (HCC) in whom percutaneous image-guided radiofrequency (RF) ablation was used as the sole first-line anticancer treatment.

Materials And Methods: The study was performed with approval of the ethics committee, and written informed consent was obtained for all patients. From June 1, 1996, to January 1, 2003, 206 patients (143 men, 63 women; age range, 51-81 years; mean age, 67 years +/- 7) who were excluded from surgery and who had Child class A or B cirrhosis with either a single HCC less than or equal to 5 cm in diameter or multiple (as many as three) HCCs less than or equal to 3 cm in diameter each were enrolled.

Radiofrequency ablation of lung malignancies: where do we stand?

Percutaneous radiofrequency (RF) ablation is a minimally invasive technique used to treat solid tumors. Because of its ability to produce large volumes of coagulation necrosis in a controlled fashion, this technique has gained acceptance as a viable therapeutic option for unresectable liver malignancies. Recently, investigation has been focused on the clinical application of RF ablation in the treatment of lung malignancies.
