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

July 29, 2020 updated by: Jonsson Comprehensive Cancer Center

Glucose Metabolic Response by PET/CT to Sarcoma Treatments

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.

Experimental: positron emission tomography computed tomography (PET/CT)
The first PET/CT scan will be performed as part of clinical evaluation of sarcoma; The second PET/CT scan will be performed 6 weeks after the start of chemotherapy treatment OR 6 weeks after the end of radiation therapy, to monitor response of sarcoma to treatment.
Procedure: positron emission tomography computed tomography (PET/CT)
The first PET/CT scan will be performed as part of clinical evaluation of sarcoma; The second PET/CT scan will be performed 6 weeks after the start of chemotherapy treatment OR 6 weeks after the end of radiation therapy, to monitor response of sarcoma to treatment.
