Interventional Study.
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 (NCT02926729). This is a study registration, not published results. Lead sponsor: Beth Israel Deaconess Medical Center. Recruitment status: TERMINATED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 56 participants (ACTUAL). Conditions: Breast Cancer. Interventions: DEVICE: nonlinear microscopy imaging of excised surgical margins; PROCEDURE: standard lumpectomy without nonlinear microscopy imaging. Primary outcome measures: Rate of Recommendation for Repeat Surgery on Postoperative Histopathology , From surgery to postoperative pathology reporting, up to 1 month. Brief summary: This research is studying a new investigative imaging instrument called a nonlinear microscope (NLM). A nonlinear microscope can produce images similar to an ordinary pathologist's microscope, but without first processing tissue to make slides. This study will determine if a NLM can be used to evaluate tissue during lumpectomy surgery for breast cancer in order to reduce the probability that standard pathologic examination of the specimen after the end of the operation will find close or positive margins, thus possibly requiring the patient to have additional breast surgery.
