Purpose Little is known about whether baseline health-related quality of life (HRQoL) scores also could predict occurrence radiotherapy-related toxicities, which we aim to assess in this study. Methods This study analyzed data from 200 patients enrolled in randomized study investigating the utility of HRQoL. HRQOL was assessed at baseline and duri...
Article
Background: Advances in screening and treatment have led to increase in breast cancer (BC) survival in recent years but prognoses for metastatic BC remain poor with poorer outcomes as health-related quality of life (HRQOL). Treatment as bevacizumab and paclitaxel for metastatic BC, although that can increase time to progression of disease, often ca...
Article
Background Obesity has previously been correlated with poorer survival in both early and metastatic breast cancer. Adipose tissues release proangiogenic factors such as Insulin-like Growth Factor and Vascular Endothelial Growth Factor that may ultimately promote tumor growth. CTscan can be used to measure the visceral fat area (VFA) and the subcuta...
Article
Background: In patients with metastatic breast cancer (mBC), Circulating Tumor Cells (CTC) counts have a strong prognostic impact on progression free survival (PFS) and overall survival (OS). Changes 4 weeks after the start of a new line of therapy, inform on treatment efficacy. Despite improvements in systemic treatment, metastatic BC remains main...
