Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must have received first line standard chemotherapy and/or radiation therapy for neuroendocrine malignancy in the past and failed the therapy.
  • Patients must have evidence of residual multifocal active tumor.
  • All patients must sign an informed consent indicating the awareness of the investigational nature of the studies involved.
  • All patients must have a Karnofsky performance status of at least 60.
  • Patients must be greater than 18 years of age.
  • Patients must have measurable and/or followable disease based on either clinical or radiologic exam.
  • Sensitivity to Indium-111 pentetreotide or any of its components is an absolute contraindication to participation in this trial.
  • An absolute contraindication is pregnancy as evidenced by the clinical condition, a positive pregnancy test (B-HCG or pelvic ultrasound).
  • If patients have received prior radionuclide therapy of the same product, there must be documented response to that therapy and/or residual active stable disease.

Exclusion Criteria:

  • Karnofsky performance status of 50 or less.
  • Patients who are unable to give informed consent.
  • Patients under 18 years of age. There will be no upper age discrimination.
  • Patients who are pregnant or those potentially pregnant subjects not willing to practice effective contraceptive techniques during the study period.
  • Patients with renal insufficiency as defined by a calculated creatinine clearance (based on age, weight and serum creatinine) of 39.9 ml/min or less.
