ABSTRACT
BACKGROUND: This phase II study combined aflibercept with preoperative chemoradiation for patients with stage II/III rectal cancer, followed by mFOLFOX6/aflibercept. METHODS: Patients received preoperative 5-FU (days 1-43), radiation (weeks 1-6), and aflibercept (days 1-15) each 28 day cycle for 6 weeks. Six weeks following the last aflibercept dose, patients underwent surgical resection. Four cycles of mFOLFOX6 plus aflibercept began 8 weeks after surgery. RESULTS: Common treatment-related toxicities included diarrhea, fatigue, and mucositis. The pCR rate was 23%. DISCUSSION: Afilbercept plus 5-FU-based chemoradiation was tolerated in patients with localized rectal cancer and showed a pCR rate within range of historical data.

Best practice (BP) in cancer care consists of a multifaceted approach comprising individualized treatment plans, evidence-based medicine, the optimal use of supportive care and patient education. We investigated the impact of a BP program in patients with relapsed/refractory multiple myeloma (RRMM) receiving selinexor. Features of the BP program that were specific to selinexor were initiating selinexor at doses ≤80 mg once weekly and the upfront use of standardized antiemetics. Study endpoints included time to treatment failure (TTF), duration of therapy, dose limiting toxicities and overall survival. Comparative analysis on TTF and duration of therapy was conducted using a log-rank test and multivariate Cox proportional hazard regression. Over the ensuing 12-month post-BP period, 41 patients received selinexor-based therapy compared to 68 patients who received selinexor-based therapy pre-BP implementation. Patients treated in the post-BP period had reductions in TTF (hazard ratio [HR] = 0.50; 95% CI: 0.27 to 0.92). Patients in the pre-BP period were four times more likely to stop therapy than those in the post-period (odds ratio [OR] = 4.0, 95% CI: 1.75 to 9.3). The findings suggest a BP program tailored to selinexor could increase the time to treatment failure, increase treatment duration and lower the incidence of drug limiting toxicities.
