Randomized Controlled Trial Comparative Study
Differences in attitudes and beliefs toward end-of-life care between hematologic and solid tumor oncology specialists.
Patients with hematologic malignancies often receive aggressive care at the end-of-life. To better understand the end-of-life decision-making process among oncology specialists, we compared the cancer treatment recommendations, and attitudes and beliefs toward palliative care between hematologic and solid tumor specialists. ⋯ We found significant differences in attitudes and beliefs toward end-of-life care between hematologic and solid tumor specialists, and identified opportunities to standardize end-of-life care.

Randomized Controlled Trial
Axitinib dose titration: analyses of exposure, blood pressure and clinical response from a randomized phase II study in metastatic renal cell carcinoma.
In a randomized, double-blind phase II trial in patients with metastatic renal cell carcinoma (mRCC), axitinib versus placebo titration yielded a significantly higher objective response rate. We evaluated pharmacokinetic and blood pressure (BP) data from this study to elucidate relationships among axitinib exposure, BP change, and efficacy. ⋯ Optimal axitinib exposure may differ among patients with mRCC. Pharmacokinetic or BP measurements cannot be used exclusively to guide axitinib dosing. Individualization of treatment with vascular endothelial growth factor receptor tyrosine kinase inhibitors, including axitinib, is thus more complex than anticipated and cannot be limited to a single clinical factor.

HER2 mutations and amplifications have been identified as oncogenic drivers in lung cancers. Dacomitinib, an irreversible inhibitor of HER2, EGFR (HER1), and HER4 tyrosine kinases, has demonstrated activity in cell-line models with HER2 exon 20 insertions or amplifications. Here, we studied dacomitinib in patients with HER2-mutant or amplified lung cancers. ⋯ NCT00818441.

Genetic aberrations affecting the c-ros oncogene 1 (ROS1) tyrosine kinase gene have been reported in a small subset of patients with non-small-cell lung cancer (NSCLC). We evaluated whether ROS1-chromosomal rearrangements could be detected in circulating tumor cells (CTCs) and examined tumor heterogeneity of CTCs and tumor biopsies in ROS1-rearranged NSCLC patients. ⋯ We provide the first proof-of-concept that CTCs can be used for noninvasive and sensitive detection of ROS1 rearrangement in NSCLC patients. CTCs from ROS1-rearranged patients show considerable heterogeneity of ROS1-gene abnormalities and elevated numerical CIN, a potential mechanism to escape ROS1-inhibitor therapy in ROS1-rearranged NSCLC tumors.

Randomized Controlled Trial Multicenter Study Comparative Study
Aprepitant versus metoclopramide, both combined with dexamethasone, for the prevention of cisplatin-induced delayed emesis: a randomized, double-blind study.
A combination of aprepitant, a 5-HT3 receptor antagonist (r.a.), and dexamethasone is recommended for the prophylaxis of cisplatin-induced nausea and vomiting in the acute phase, and aprepitant + dexamethasone (A + D) in the delayed phase. The aim of this study was to verify if A + D is superior to metoclopramide plus dexamethasone (M + D) in preventing delayed emesis in cancer patients receiving the same prophylaxis for acute emesis. ⋯ NCT00869310.
