The purpose of this study is to evaluate the effect of primary tumor resection on the metabolic activity of metastases in patients with a colorectal primary tumor and synchronous liver metastases by positron emission tomography (PET) with 2-deoxy-2-fluoro[18F]-D-glucose (FDG-PET) scanning.

Condition Intervention
Colorectal Neoplasms Procedure: FDG-PET

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Exploratory Study on FDG-PET Scanning in Evaluating the Metabolic Activity of Liver Metastases Before and After Resection of the Primary Tumor in Patients With a Colorectal Malignancy

Further study details as provided by Radboud University:

Primary Outcome Measures:
  • Increase in metabolic activity of liver metastases after resection of the primary tumor compared to the activity of metastases in patients without primary tumor resection

Estimated Enrollment: 30
Study Start Date: September 2003
Estimated Study Completion Date: December 2008
Detailed Description:
The goal of this study is to evaluate the activity of liver metastases before and after resection of the primary tumor. Non-invasive assessment of tumor metabolism is possible in vivo by means of positron emission tomography (PET)-scanning. Therefore, FDG-PET scan offers a suitable approach to determine the influence of removal of a primary colorectal tumor on metabolic activity of the liver metastases. The FDG uptake in the liver metastases is quantified by calculating standardised uptake values (SUVs).

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
