indium in 111 pentetreotide in treating patients with refractory cancer

Conditions: Brain and Central Nervous System Tumors; Childhood Langerhans Cell Histiocytosis; Gastrointestinal Carcinoid Tumor; Head and Neck Cancer; Intraocular Melanoma; Islet Cell Tumor; Kidney Cancer; Lung Cancer; Melanoma (Skin); Neoplastic Syndrome; Neuroendocrine Carcinoma of the Skin; Pheochromocytoma

Summary: rationale: radiation therapy uses high-energy x-rays and other sources to damage tumor cells. giving radiation therapy in different ways may kill more tumor cells. purpose: phase i trial to study the effectiveness of indium in 111 pentetreotide in treating patients who have refractory cancer.

objectives: i. determine the maximum tolerated dose (mtd), toxic effects, and the preliminary antitumor activity of indium in 111 pentetreotide. outline: this is a dose escalation study. patients receive indium in iii pentetreotide (octreoscan) iv on day 1. imaging is conducted on days 3 and 6. treatment continues weekly for a total of 4 courses in the absence of disease progression or unacceptable toxicity. cohorts of at least 3 patients receive escalating doses of octreoscan until the maximum tolerated dose (mtd) is determined. the mtd is defined as the dose preceding that at which 2 of 3 patients experience dose limiting toxicities. patients are followed every 3 months for the first year, then every 6 months thereafter. projected accrual: up to 35 patients will be accrued for this study.

Eligibility criteria:
disease characteristics: histologically proven malignancy with no alternate treatments available measurable or evaluable progressive disease somatostatin receptors present on tumor and uptake demonstrated on diagnostic scan with octreoscan patient characteristics: age: 18 and over performance status: ecog 0-2 life expectancy: at least 3 months hematopoietic: platelet count at least 100,000/mm3 absolute neutrophil count at least 1,500/mm3 hepatic: total bilirubin no greater than 2.0 mg/dl renal: creatinine clearance at least 40 ml/min other: no active infections not hiv positive no coexisting medical condition not pregnant or nursing negative pregnancy test fertile patients must use effective contraception prior concurrent therapy: biologic therapy: not specified chemotherapy: at least 4 weeks since prior chemotherapy (6 weeks for nitrosoureas or mitomycin) endocrine therapy: not specified radiotherapy: at least 4 weeks since prior wide field radiation therapy surgery: recovery from prior surgery
