title: Design of phase II clinical trials in cancer using decision theory.
abstract: An application of decision theory to the design of phase II clinical trials in cancer is presented. A risk function which depends on the prior distribution of the response rate, the costs of treating a patient, and the gains or losses resulting from the decision taken upon completion of the study is derived and optimal restricted sampling plans for a response rate of 20% are provided.
