Abstract BACKGROUND The optimal observation interval after the radiosurgical treatment of a sporadic vestibular schwannoma, prior to salvage intervention, is unknown. OBJECTIVE To determine an postradiosurgical for differentiating between pseudoprogression and true tumor growth by analyzing serial volumetric data. METHODS This single-institution retrospective study included all schwannomas treated with Gamma Knife radiosurgery (Eketa AB, Stockholm, Sweden; 12–13 Gy) from 2002 2014....

Abstract: The anticancer properties of tea catechins are most frequently attributed to the principal catechin (‐)‐epigallocatechin‐3‐gallate (EGCg). Efficacy was evaluated using growth cultured HeLa cells and inhibition enzymatic activity a putative cell surface target enzyme, cancer‐associated surface‐located NADH oxidase (ECTO‐NOX) designated tNOX. amounts EGCg required inhibit by both criteria reduced 10 times combination with inactive such as (‐)‐epicatechin (EC), (‐)‐epigallocatechin...

Objective Differentiating pseudoprogression from true tumor growth is a difficult clinical problem in the management of vestibular schwannomas after radiosurgery. Controversy exists regarding how much tolerance clinician should have for enlargement following treatment, before recommending salvage therapy. In this study, we sought to describe distribution volume behaviors radiosurgery, identify factors associated with transient growth, and an ideal timeframe differentiating pseudoprogression.
