Background: Activating mutations of the tyrosine kinase receptor KIT have been described in both mastocytosis and gastrointestinal stromal tumors (GIST), but are usually found in separate domains and often respond differently to signal transduction inhibitors. We describe here a large family with both GIST, mastocytosis, and achalasia. Affected family members have a unique activating mutation in exon 9 of KIT which show promise to a novel signal transduction inhibitor.

The acai berry is an example of a plant rich in phytochemicals, which may slow the growth of prostate cancer.
Methods: This was a phase II, Simon 2-stage clinical trial in patients with biochemically recurrent prostate cancer with a primary endpoint of prostate-specific antigen (PSA) response.
