PET Imaging to Determine the Role of PET in the Assessment of Regional Disease in Breast Cancer (PET PREDICT Trial)

The overall goal of this study is to determine how FDG-PET can be incorporated into the assessment of the axilla in the staging and treatment of women with early stage breast cancer.

A multicentre, prospective, diagnostic accuracy study will be conducted evaluating the ability of positronic emission tomography using fluorodeoxyglucose (FDG-PET) to detect the presence or absence of axillary lymph node metastases in newly diagnosed breast cancer patients with no clinical evidence of spread of disease beyond the breast.

Condition Intervention Phase
Breast Cancer Procedure: PET scan Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Prospective Study to Determine the Role of 2-[18F]Fluoro-2-Deoxy-D-Glucose (FDG)Positron Emission Tomography (PET)in the Assessment of Regional Nodal Spread of Disease in Breast Cancer Patients

Further study details as provided by Ontario Clinical Oncology Group (OCOG):

Primary Outcome Measures:
  • The primary outcomes are the sensitivity and specificity of FDG-PET in axillary node assessments using axillary node assessment [Sentinel Node Biopsy(SNB) with or without Axillary Node Dissection (AND)] as the reference standard.

Secondary Outcome Measures:
  • Patients with positive FDG-PET in non-axillary nodal areas;
  • Patients with positive FDG-PET in other non-nodal areas;
  • Patients with positive FDG-PET in the residual breast tissue.

Enrollment: 336
Study Start Date: February 2005
Study Completion Date: May 2007
Detailed Description:
Patients will have histologic confirmation of invasive breast cancer and will have a FDG-PET scan prior to axillary node assessment. All patients will have a sentinel node biopsy if any sentinel nodes can be located. Patients with a positive sentinel node will have an axillary node dissection. The results of the PET will be compared to the reference standard of histologic examination of all excised (sentinel and non-sentinel) axillary lymph nodes which will be referred to as axillary node assessment. Sensitivity, specificity, positive and negative predictive values for PET-FDG will be determined.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologic diagnosis of invasive breast cancer,
  • Resectable primary cancer.

Exclusion Criteria:

  • The diagnosis of invasive breast cancer was made more than 3 months prior to registration,
  • Patient and/or surgeon are not willing to proceed with a SNB or AND after the PET scan is completed,
  • Patient and/or surgeon are not willing to proceed with a level I and II AND if the SNB is positive, if the PET scan shows increased uptake in the ipsilateral axilla, or if the surgeon is still gaining experience in the performance of SNB,
  • SNB or AND has already been done,
  • Chemotherapy has been given or will be given prior to PET scan or SNB or AND,
  • Significant serious concurrent medical problems (e.g., uncontrolled diabetes),
  • Patient is pregnant or lactating,
  • Patient is unable to lie supine and with both arms above their heads for PET scan,
  • Known hypersensitivity to FDG,
  • Clinical evidence of regional nodal metastases (fixed, matted axillary nodes),
  • Clinical evidence of distant metastases.
