10. Staging
For breast cancer patients without symptoms suggestive of metastases at clinical stage 3, the ECIBC's Guidelines Development Group (GDG):
- recommends using conventional staging exams, if positron emission tomography-computed tomography (PET-CT) is not readily available (strong recommendation, moderate certainty of the evidence)
- suggests using positron emission tomography-computed tomography (PET-CT) alone rather than conventional staging exams or the combination of conventional staging exams plus PET-CT (conditional recommendation, low certainty of the evidence)
Stage 3: conventional exams plus PET-CT
Issued on: September 2018
Healthcare question
Should conventional staging exams followed by fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) staging vs. conventional staging exams be used for patients with clinical stage III breast cancer without symptoms suggestive of metastases?
Recommendation
For patients with clinical stage III breast cancer without symptoms suggestive of metastases, the ECIBC's Guidelines Development Group (GDG) suggests using conventional staging followed by positron emission tomography-computed tomography (PET-CT) over conventional staging alone.
Recommendation strength
| Conditional recommendation |
| Low certainty of the evidence |
Justification
The conditional recommendation is a result of a balance of effects that probably favours the intervention (conventional staging followed by PET-CT) but has moderate costs and probably reduces equity.
