Brief Summary:
The purpose of this study is to learn more about the effectiveness and side effects of lithium treatment for subjects with low-grade neuroendocrine tumors.

Condition or disease Intervention/treatment Phase
Neuroendocrine Tumors Drug: Lithium Carbonate Phase 2

Detailed Description:
Lithium 300mg by mouth, three times daily, escalating to a lithium level of 0.8-1.0; Continue until progressive disease/unacceptable toxicity;Evaluate q 8 weeks.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 15 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Clinical and Biological Study of Lithium Carbonate in Patients With Low-Grade Neuroendocrine Tumors
Study Start Date : July 2007
Actual Primary Completion Date : June 2009
Actual Study Completion Date : June 2009

Arm Intervention/treatment
Experimental: Lithium
Lithium carbonate will be dosed on a flat scale of mg/day and not by weight or body surface area (BSA). Lithium carbonate will be provided as a 300mg tablet and will be taken daily without breaks in treatment.
Drug: Lithium Carbonate
Lithium 300mg PO TID escalating to a lithium level of 0.8-1.2. Lithium carbonate will be administered the first week at 300 mg flat dose three times each day. A serum lithium level will be checked after 4-5 days of treatment by drawing a blood sample prior to the morning dose of lithium. Evaluate every 8 weeks.

Primary Outcome Measures :
  1. Tumor Response Rate Measured by the Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Up to 4 years ]
    Per Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR) >=30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD) >=20% increase in the sum of the longest diameter of target lesions; Stable Disease (SD), small changes that do not meet the above criteria.

Secondary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Up to 4 years ]
    Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. Progression free survival is measured from the date of entry on the study to the appearance of new metastatic lesions or objective tumor progression. If a participant did not experience an event of disease progression or death at the time of analysis (03/10/2011), then the patient's data was censored at the date of the last available evaluation.

  2. Overall Survival (OS) [ Time Frame: Up to 4 years ]
    Overall survival for a participant is defined as the number of days from the day of first Lithium administration to the participant's death. As of the time of analysis (03/10/2011), median overall survival duration was not reached.
