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

Canada336 participantsStarted 2005-02

Plain-language summary

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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

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.
