Phase 4 Trial.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT00904410). This is a study registration, not published results. Lead sponsor: Centre Oscar Lambret. Recruitment status: COMPLETED. Phase: PHASE4. Study type: INTERVENTIONAL. Enrollment: 63 participants (ACTUAL). Conditions: Breast Cancer. Interventions: OTHER: FDG-PET. Primary outcome measures: Variation rate of SUV(BSA max)before and after the 1st cycle of neoadjuvant chemotherapy , before and 3 weeks after 1st cycle. Brief summary: 18F-FDG PET, a whole-body imaging technology based on glucose metabolism, can effectively detect subclinical and clinical therapeutic responses at stages that are earlier than those detected by conventional approaches. We propose to conduct a prospective study to evaluate early therapeutic response using 18F-FDG PET before and after the 1st cycle of neo-adjuvant chemotherapy for breast cancer patients. Variation of 18F-FDG PET uptake is compared to clinical and echographical tumor response evaluated after 3 cycles of chemotherapy. The purpose is to estimate the capacity of 18F-FDG PET to differentiate responder and non-responder patients.
