Evaluation of the Effects of Chemotherapy on the Uptake and Retention of Carbon 11 Methionine in Prostate Cancer Patients

October 30, 2009 updated by: Dana-Farber Cancer Institute

An Evaluation of the Effects of Chemotherapy on the Uptake and Retention of Carbon 11 Methionine (C11 MET) in Prostate Cancer, as Assessed by Positron Emission Tomography (PET)

The purpose of this study is to better understand a new type of radiology test called positron emission tomography (PET) with carbon 11 methionine to determine which patients have a beneficial effect from anti-cancer therapy with the drug docetaxel.

Detailed Description

In the week before the patients first dose of chemotherapy they will receive a C11 methionine PET scan which takes about 90 minutes. C11 methionine is a radioactively labeled amino acid that is given to the patient intravenously.

Eighteen to twenty days after the patients first dose of docetaxel chemotherapy, they will have another C11 methionine PET scan which is identical to the first scan.

At the end of three cycles of docetaxel chemotherapy (about 2 and 1/2 months on study) another C11 methionine PET scan will be done.

The PET scans will show how well the tumor is taking up methionine.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
To describe the association between percent change in tumor standardized uptake value (SUV) after c11 methionine administration after one cycle of every three-week docetaxel-based chemotherapy and prostate-specific antigen (PSA) response

Secondary Outcome Measures

Outcome Measure
To explore the relative value of the change in tumor SUV after C11 methionine administration after one cycle and 3 cycles of docetaxel with respect to PSA progression
to explore optimal cutpoints and measures of SUV change for distinguishing responders from non-responders and progressors from non-progressors and
to evaluate the relationship between the percent change is tumor SUV after C11 methionine administration with freedom from PSA progression in 6 months
