Reporting Groups

	Description
Sirolimus Patients	sirolimus 6 mg by mouth loading dose and 2 mg by mouth daily in a 28 day treatment cycle. Patients who do not have cancer take the drug for a total of two cycles (56 days) unless they develop unacceptable side effects. Those who have cancer may continue sirolimus beyond cycle 2 until their disease worsens or they develop unacceptable side effects.
