Stereotactic or conformal radiotherapy for adrenal metastases: Patient characteristics and outcomes in a multicenter analysis.

To report outcome (freedom from local progression [FFLP], overall survival [OS] and toxicity) after stereotactic, palliative or highly conformal fractionated (>12) radiotherapy (SBRT, Pall-RT, 3DCRT/IMRT) for adrenal metastases in a retrospective multicenter cohort within the framework of the German Society for Radiation Oncology (DEGRO). Adrenal metastases treated with SBRT (≤12 fractions, biologically effective dose [BED10] ≥ 50 Gy), 3DCRT/IMRT (>12 fractions, BED10 ≥ 50 Gy) or Pall-RT (BED10 < 50 Gy) were eligible for this analysis. In addition to unadjusted FFLP (Kaplan-Meier/log-rank), we calculated the competing-risk-adjusted local recurrence rate (CRA-LRR).

To combine or not combine: the role of radiotherapy and targeted agents in the treatment for renal cell carcinoma.

Introduction: Renal cell carcinoma is counted among the most resistant tumors to chemotherapy and radiotherapy, respectively. However, therapeutic options expanded since the introduction of molecular agents, targeting specific pathways such as the vascular endothelial growth factor (VEGF)-α, the VEGF receptor (VEGFR), or the mammalian target of rapamycin (mTOR) pathway. These new agents almost doubled the time to tumor progression and in some trials even improved overall survival.

Optimized high gradient magnetic separation for isolation of Plasmodium-infected red blood cells.

Background: Highly purified infected red blood cells (irbc), or highly synchronized parasite cultures, are regularly required in malaria research. Conventional isolation and synchronization rely on density and osmotic fragility of irbc, respectively. High gradient magnetic separation (HGMS) offers an alternative based on intrinsic magnetic properties of irbc, avoiding exposure to chemicals and osmotic stress.
