Radiolabeled Octreotide in Treating Children With Advanced or Refractory Solid Tumors

Overview

RATIONALE: Radiolabeled octreotide can locate tumor cells and deliver radioactive tumor-killing substances to them without harming normal cells. PURPOSE: This phase I trial is to study the safety and effectiveness of radiolabeled octreotide in treating children who have advanced or refractory solid tumors.
