Lene Thorsen, Kerry S. Courneya, Jostein Steene‐Johannessen, Jon Michael Gran, more

International Journal of Cancer > 153 > 8 > 1512 - 1519

Physical activity (PA) has been associated with reduced mortality among cancer survivors, but no study has focused on testicular cancer survivors (TCSs). We aimed to investigate the association of PA measured twice during survivorship with overall mortality in TCSs. TCSs treated during 1980 to 1994 participated in a nationwide longitudinal survey between 1998 to 2002 (S1: n = 1392) and 2007 to 2009...

The impact of exercise on growth factors (VEGF and FGF2): results from a 12-month randomized intervention trial

Darren R. Brenner, Yibing Ruan, Scott C. Adams, Kerry S. Courneya, more

European Review of Aging and Physical Activity > 2019 > 16 > 1 > 1-6

Background Vascular endothelial growth factor (VEGF) and Fibroblast growth factor-2 (FGF2) are angiogenic cytokines in normal tissues and tumors. Evidence suggests that increased growth factor expression in adipose tissue leads to improved vascularity and decreased hypoxia, fibrosis, and inflammation, which may, in turn, reduce post-menopausal breast cancer risk. Objective We investigated whether...
