Phase I dose-escalation study of nab-paclitaxel combined with cisplatin and capecitabin as induction chemotherapy followed by concurrent chemoradiotherapy in patients with nasopharyngeal carcinoma.

Background And Purpose: Nab-paclitaxel is a promising albumin-bound paclitaxel with a therapeutic index superior to that of docetaxel, but the optimal dose of nab-paclitaxel combined with cisplatin and capecitabine as induction chemotherapy followed by concurrent chemoradiotherapy for patients with locally advanced nasopharyngeal carcinoma remains unknown.

Materials And Methods: This was an open-label, single-arm study investigating the safety and efficacy of nab-paclitaxel + cisplatin + capecitabin as IC for three cycles, followed by cisplatin CCRT, conducted by using the standard "3 + 3" design in LA-NPC. If more than one-third of the patients in a cohort experienced dose-limiting toxicity (DLT), the dose used in the previous cohort was designated the maximum tolerated dose (MTD).

A deep learning-based semiautomated workflow for triaging follow-up MR scans in treated nasopharyngeal carcinoma.

It is imperative to optimally utilize virtues and obviate defects of fully automated analysis and expert knowledge in new paradigms of healthcare. We present a deep learning-based semiautomated workflow (RAINMAN) with 12,809 follow-up scans among 2,172 patients with treated nasopharyngeal carcinoma from three centers (ChiCTR.org.

Radiomic signatures reveal multiscale intratumor heterogeneity associated with tissue tolerance and survival in re-irradiated nasopharyngeal carcinoma: a multicenter study.

Background: Post-radiation nasopharyngeal necrosis (PRNN) is a severe adverse event following re-radiotherapy for patients with locally recurrent nasopharyngeal carcinoma (LRNPC) and associated with decreased survival. Biological heterogeneity in recurrent tumors contributes to the different risks of PRNN. Radiomics can be used to mine high-throughput non-invasive image features to predict clinical outcomes and capture underlying biological functions.
