valproic acid and Adenocarcinoma, Follicular

valproic acid has been researched along with Adenocarcinoma, Follicular in 4 studies

Valproic Acid: A fatty acid with anticonvulsant and anti-manic properties that is used in the treatment of EPILEPSY and BIPOLAR DISORDER. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of VOLTAGE-GATED SODIUM CHANNELS.
valproic acid : A branched-chain saturated fatty acid that comprises of a propyl substituent on a pentanoic acid stem.

Adenocarcinoma, Follicular: An adenocarcinoma of the thyroid gland, in which the cells are arranged in the form of follicles. (From Dorland, 27th ed)

Best Overall Response

Best overall response was assessed by radioiodine uptake. Complete response (CR) is increased Rai (radioiodine) uptake on post- valproic acid therapy at week 10, AND a decrease in Tg (thyroglobulin ) level to less than 2 ng/ml (or a decrease in Tg-Ab (thyroglobulin antibodies) level to less than 2.0 IU/ml) at 10 weeks AND disappearance of all lesions at 16 weeks. Partial response (PR) is increased Rai uptake on post-valproic scan at week 10, OR a decreased Tg level (or a decrease in Tg Ab (Tg antibody) level by more than 20%) at 10 weeks AND 30% decrease in target lesion at 16 weeks. Stable disease (SD) is no change in RAI uptake AND Tg levels (or TG-Ab level) AND no significant change of lesions at 16 weeks. Progressive disease (PD) is tumor mass increases OR Tg levels (or Tg-Ab levels) increases over 10 weeks OR at least 20% increase in target lesion at 16 weeks. (NCT01182285)
Timeframe: Week 16

NIS (Na/I-symporter) Expression

NIS (Na/I-symporter) Expression is assessed by quantitative reverse transcription (RT) polymerase chain reaction (PCR) and immunohistochemistry (IHC). NIS mRNA expression was measured by quantitative RT PCR from biopsy samples. (NCT01182285)
Timeframe: Entry to study and after 10 weeks of treatment

RAI (Radioactive Iodine) Uptake and Tg (Thyroglobulin) Level Compared Pre and Post- Valproic Treatment

Complete response (CR) is increased Rai uptake on post- valproic acid therapy at week 10, AND a decrease in Tg level to less than 2 ng/ml (or a decrease in Tg-Ab level to less than 2.0 IU/ml) at 10 weeks AND disappearance of all lesions at 16 weeks. Partial response (PR) is increased Rai uptake on post-valproic scan at week 10, OR a decreased Tg level (or a decrease in Tg Ab (Tg antibody) level by more than 20%) at 10 weeks AND 30% decrease in target lesion at 16 weeks.

Timeframe: Entry to study and after 10 weeks of treatment for Phase 1, and 10 weeks of treatment to 16 weeks of treatment for phase 2.
