PET Scan Combined With CT Scan in Evaluating Treatment Response in Patients Undergoing Treatment for Bone Cancer or Soft Tissue Sarcoma

Not Applicable
Completed
Conditions
Sarcoma
Interventions
Procedure: positron emission tomography computed tomography (PET/CT)
Registration Number
NCT00335751
Lead Sponsor
Jonsson Comprehensive Cancer Center
Brief Summary

RATIONALE: Diagnostic procedures, such as PET scan and CT scan, may help doctors determine the extent of cancer and predict a patient's response to treatment and help plan the best treatment.

PURPOSE: This clinical trial is studying how well PET scan combined with CT scan evaluates treatment response in patients undergoing treatment for bone cancer or soft tissue sarcoma.

Detailed Description

OBJECTIVES:

* Determine whether an FDA-approved device that combines fludeoxyglucose \^18F positron-emission tomography (FDG-PET) and CT scanning (FDG-PET/CT) can accurately locate and determine the extent of disease in patients who are undergoing treatment for bone or soft tissue sarcoma.

* Determine whether FDG-PET/CT scanning is effective in evaluating the response of sarcoma to treatment.

* Determine whether the new FDG-PET/CT device improves the ability to evaluate treatment response early and accurately.

* Correlate changes in glucose metabolic activity early and late after treatment with overall and progression-free survival.

* Correlate changes in glucose metabolic activity early and late after treatment with degree of tumor necrosis at the time of surgery.

OUTLINE: This is a prospective, pilot study. Patients are stratified according to disease (high-grade soft tissue sarcoma vs low-grade soft tissue sarcoma vs osteosarcoma).

Patients undergo fludeoxyglucose \^18F positron-emission tomography (FDG-PET)/CT scanning at baseline and then within 2 weeks and 12 weeks after the start of treatment (total of 3 scans).

PROJECTED ACCRUAL: A total of 120 patients will be accrued for this study.
