Prognostic factors of survival in patients with advanced cancer admitted to home care
2011
Abstract CONTEXT: Data regarding prognostication of life expectancy in patients with advanced cancer are of paramount importance to patients, families, and clinicians. However, data regarding patients followed at home are lacking. OBJECTIVES: The aim of this study was to evaluate the correlation between various factors recorded at the beginning of home care assistance and survival. METHODS: A sample of consecutive patients admitted to two home care programs was surveyed. A preliminary consensus was achieved as to the possible variables easy to be recorded at home. These included age at the time of home care admission, gender, residence, marital status, primary cancer diagnosis, Karnofsky Pe…
Paclitaxel and beta-lapachone synergistically induce apoptosis in human retinoblastoma Y79 cells by downregulating the levels of phospho-Akt.
2009
Paclitaxel (PTX) and beta-lapachone (LPC) are naturally occurring compounds that have shown a large spectrum of anticancer activity. In this article we show for the first time that PTX/LPC combination induces potent synergistic apoptotic effects in human retinoblastoma Y79 cells. Combination of suboptimal doses of PTX (0.3 nM) and LPC (1.5 microM) caused biochemical and morphological signs of apoptosis at 48 h of treatment. These effects were accompanied by potent lowering in inhibitor of apoptosis proteins and by activation of Bid and caspases 3 and 6 with lamin B and PARP breakdown. PTX/LPC combination acted by favoring p53 stabilization through a lowering in p-Akt levels and in ps166-MDM…
