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.
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.
Interventions
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.

| Measure | Time frame | Description |
|---|---|---|
| Progression Free Survival (PFS) | 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. |
| Overall Survival (OS) | 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. |

Progression Free Survival (PFS)
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.
