Purpose
The objective of this trial is to assess the value of 18F-choline PET/CT for the detection of regional lymph node metastases from prostate cancer. In addition, we want to evaluate whether 18F-choline PET/CT can replace lymphadenectomy for the staging of prostate cancer.

Procedure: [18F] Fluorocholine PET/CT |

| Study Type: | Interventional |
| Study Design: | Diagnostic, Non-Randomized, Double Blind (Subject, Caregiver, Investigator), Single Group Assignment, Efficacy Study |
| Official Title: | Evaluation of [18F] Fluorocholine PET/CT for Detection of Regional Lymph Node Metastases From Prostate Cancer |
| Estimated Enrollment: | 205 |
| Study Start Date: | January 2008 |
| Estimated Study Completion Date: | December 2010 |
| Estimated Primary Completion Date: | September 2010 (Final data collection date for primary outcome measure) |
The patients fast 6 hours before the [18F]Fluorocholine PET/CT scan. [18F]Fluorocholine will be used as tracer with a dosage of 4 MBq per kg bodyweight. PET/CT imaging will be performed after 15 and 60 after the intravenous injection of the tracer. The patient will receive 2 full body FCH PET/CT. The CT scan is with contrast.
The radiation exposure from the CT scan is 9 mSv and from the PET scan it is 3 mSv, giving a total of 12 mSv, which equals 4 times the yearly background radiation in Denmark.
The purpose of this prospective trail is to improve the staging of patients with prostate cancer. We focus on the group of patients with a newly diagnosed prostate cancer, and specifically the ones who have an intermediate and high risk of disseminated prostate cancer.
It is our aim to improve staging by replacing the traditional invasive method, the lymphadenectomy, which has a rather low sensitivity by a non-invasive method, 18F-choline PET/CT which has a presumably superior sensitivity.
The treatment of patients with prostate cancer relies on the stage of the disease. Patients with disseminated prostate cancer are incurable and are treated with palliatively. In contrast, patients with localized prostate cancer are offered curative therapy. Hence, the stage of prostate cancer is crucial for the choice of treatment.
The potential benefits are
The patients are 18F-choline PET/CT scanned prior to their lymphadenectomy, the results of the 18F-choline PET/CT are blinded for the surgeon. The endpoint of the trail is the comparison of 18F-choline PET/CT and the histopathological investigation of the regional lymph nodes of prostate.
Assuming a prevalence of metastasised prostate cancer of 20% and a true (unknown) sensitivity of FCH PET/CT of 95%, 205 patients are sufficient to show that the sensitivity of the FCH PET/CT is greater than 80% with a power of 80% at significance level 5%. The size of the confidence interval for specificity of FCH PET/CT is expected to become reasonable small. In opposition to lymphadenectomy, FCH PET/CT results may point to metastases in neighbouring regions which gives an additional benefit to FCH PET/CT justifying a test level for sensitivity of 80%."
Accordingly 205 patients will be included over 2½ years. The first patients have been included in January 2008. Interim analyses will be done after 25, 50 and 100 patients.
