Investigational drug(s) / intervention(s)

pre-pectoral IBBRsub-pectoral IBBR

pre-pectoral IBBR: The breast is reconstructed by positioning a breast implant above (pre-pectoral) the pectoralis major muscle.

sub-pectoral IBBR: The breast is reconstructed by positioning a breast implant below (sub-pectoral) the pectoralis major muscle.

Study summary

This trial is to investigate whether pre-pectoral Implant-Based Breast Reconstruction (IBBR) provides better Quality of Life (QoL) with respect to long-term (24 months) physical well-being (chest) compared to sub-pectoral IBBR for patients undergoing skin-sparing mastectomy or nipple-sparing mastectomy for prevention or treatment of breast cancer.

Primary outcome measure(s)

Change in BREAST-Q scale — within 24 months after mastectomy (screening, day 10, and months 1, 6, 12 and 24)
compare the Quality of Life (QoL) with respect to long-term physical well-being (chest) after pre-pectoral or sub-pectoral IBBR. The BREAST-Q module specific to breast reconstruction version 2.0 consists of 13 independent scales covering health-related QoL domains and satisfaction domains. Each scale is scored to generate a numerical score on a scale from 0 (worst) to 100 (best).
Change in EQ-5D-5L questionnaire — within 24 months after mastectomy (screening, day 10, and months 1, 6, 12 and 24)
The 5-level version of the EQ-5D (EQ-5D-5L) consists of the EQ-5D descriptive system that comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/Depression (5 answer levels each: no problems, slight problems, moderate problems, severe problems and extreme problems), resulting in a 1-digit number that expresses the level for that dimension. The digits for each dimension are combined into a 5-digit number that describes the patient's health state and is subsequently converted into a preference-based quality of life weight (utility) using an algorithm derived from population-based studies. In addition, patients are asked to rate their health on a vertical visual analogue scale (EQ VAS), where the anchors are labelled with 'The best health you can imagine' and 'The worst health you can imagine'.
