Cosmetic Outcome

The primary objective of this study is to determine in women with node negative BC ≤3cm in size, if PBI compared to WBI, both given once-a-day over 1 week following BCS, is non-inferior for LR and reduces adverse cosmesis. The primary outcomes are LR and patient-assessed cosmesis at 3 years post randomization.

What is the purpose of this study? The Investigators want to find out whether applying Micropore surgical tape to the medial half of the mastectomy scar for 3 months helps improve its appearance after 12 months, compared to no intervention. Why is this study important? Scars can cause discomfort and affect how people feel about their bodies. The tape is thought to reduce stress on healing skin and possibly lead to a better-looking scar. But The Investigators need strong evidence to know whether it really helps. How will the study be done? This is a randomized, observer-blinded trial. Women having mastectomy are randomly assigned to either receive the tape on half their scar or receive no tape. A plastic surgeon and a breast surgeon-who do not know which side had tape-will evaluate wounds using photos after 3 and 12 months. Patients will also rate their scars using a questionnaire (POSAS), giving their personal view on color, thickness, stiffness, and symptoms like itch or pain. What else are The Investigators looking at? The Investigators will examine whether the treated half of the scar looks better than the untreated half within the same woman-this helps control for individual skin differences. The Investigators will also compare treated versus untreated areas across different women to see if there is a consistent benefit. If the untaped half of scars looks different from control scars, this may suggest differences between the groups that affect results. What will this study reveal? It will show whether using the tape improves cosmetic outcomes after mastectomy, and whether patients and clinicians agree on how scars heal. The findings may guide better post-surgery care to reduce scars and improve confidence and quality of life.
