Dose-Finding Based on Multiple Toxicities in a Soft Tissue Sarcoma Trial
软组织肉瘤试验中基于多种毒性的剂量探索
The scientific goal of a phase I oncology trial of a new chemotherapeutic agent is to find a dose with an acceptable level of toxicity. For ethical reasons, dose-finding is done adaptively, with doses chosen for successive cohorts of patients based on the data obtained from previous cohorts. Typically, patients are at risk for several qualitatively different toxicities, each occurring at several possible severity levels. In this article, we describe how we addressed the…
