Clinical Trial Summary

The purpose of this study is to assess how the needle size 7G vs 10G affects performance indicators and patient experience in vacuum-assisted excision (VAE) of probably benign breast lesions

Description:

After being informed about the study and potential risks, all patients giving written informed consent will have a VAE procedure to remove their breast lesion and will be randomised to either 7G or 10G needle size. After completion of the procedure, the patients fill out a questionnaire to collect data on their experience. The radiologist performing the procedure fills out a form collecting procedural performance indicators.

Primary	Pain assessed by NRS 2 weeks after baseline	Patient pain level during the experience - reported by patient in a 10-level NRS	2 weeks after baseline
Secondary	Number of patients with bleeding despite 10 minutes compression	Bleeding despite 10 minutes compression - reported by radiologist	Baseline
Secondary	Radicality assessment fractions	Number of fractions possible to perform after the lesion has visually been removed - reported by radiologist	Baseline
Secondary	Self-reported number of patients who would recommend the procedure to others	Would the patient recommend the same procedure to others in same situation - reported by patient as yes or no	1 week after baseline
Secondary	Self-reported satisfaction with cosmetic result assessed by a categorical scale	How dissatisfied is the patient with the cosmetic result - reported by patient - using a categorical scale from "not at all", "somewhat", "rather", "very".	1 week after baseline
Secondary	Number of patients with self-reported occurrence of wound infection	Occurrence of wound infection - reported by patient as yes or no	1 week after baseline
Secondary	Remaining scar	Yes = Any sign of prior trauma to the skin, No = Otherwise, Reported by radiologist as assessed by visual inspection	6 months after baseline
