Clinical Outcomes of Patients With Gastrointestinal Malignancies Participating in Phase I Clinical Trials.

Objectives: Early-phase clinical trials play a pivotal role in drug development. However, limited data are available on outcomes of gastrointestinal (GI) cancer patients enrolled in phase I clinical trials. Here, we evaluated the characteristics associated with survival in GI cancer patients participating in phase I clinical trials and attempted to validate previously established prognostic models.
