Although breast reconstruction is an integral part of breast cancer treatment, there is little high-quality evidence to indicate which method is the most effective. The objective of this study is to compare implant-based and autologous breast reconstruction, in non-radiated patients. The primary outcome is patient reported breast-specific quality of life/satisfaction and the secondary outcomes are complications, factors affecting satisfaction, and cost-effectiveness. Moreover, the study aims to improve the evidence for trial decision-making in breast reconstruction. Randomized controlled trials (RCT) are generally thought to provide the most solid scientific evidence, but there are significant barriers to conducting RCTs in breast reconstruction, making both recruitment and achieving unbiased and generalisable results a challenge. The study design partially randomised patient preference trial (RPPT) might be a way to overcome these challenges. In the present study, patients who consent to randomisation will be randomised to implant-based and autologous breast reconstruction, whereas patients with strong preferences will be able to choose method. The study is designed as a superiority trial based on BREAST-Q and 124 participants will be randomised. In the preference cohort patients will be included until 62 participants have selected the least popular alternative. Follow-up will be 60-months. Embedded qualitative studies and within-trial economic evaluation will be performed.

RECRUITINGSatisfaction with the breast/s and breast-specific quality of life
Satisfaction with the breast/s and breast-specific quality of life measured with BREAST-Q reconstruction.The patient rates all items on 3-, 4-, and 5-point Likert-scales. A raw score, that is converted to a score 0-100, is calculated for each domain. A higher score indicates a greater satisfaction or better quality of life.
Time frame: 5 years
Cost-effectiveness
The net cost divided for society by changes in health outcomes measured with Breast-Q and EQ5D.
Time frame: 5 years+ simulation model based on 20 years
Complications
Complications classified as types and according to the Clavien-Dindo Classification (CDC) of surgical complications. According to CDC all complications are graded from 1 (any deviation from the normal postoperative course without the need for pharmacological treatment or surgical, endoscopic and radiological interventions) to 5 (Patient demise). Comprehensive Complication Index (CCI) scores will also be used. The CCI is calculated from CDC as the sum of all complications that are weighted for their severity, yielding a scale from 0-100. A higher CCI means more severe and more complications. All participating surgeons will be given a list of study specific definitions of complications.
Time frame: 5 years
Surgical revisions
All operations performed will be recorded and classified according to the international classification of disease in the operation planing program Orbit.
Time frame: 5 years
Satisfaction with the donor-site
Satisfaction with the donor site will be measured with the abdominal domain of Breast-Q.The patient rates all items on 3-, 4-, and 5-point Likert-scales. A raw score, that is converted to a score 0-100, is calculated for each domain. A higher score indicates a greater satisfaction or better quality of life.
Time frame: 5 years
Symptoms of depression and anxiety
Symptoms of depression and anxiety will be measured with the Hospital Anxiety and Depression Scale (HADS).The HADS is a fourteen item scale that generates: Seven of the items relate to anxiety and seven relate to depression.For both scales, scores of less than 7 indicate non-cases. 8-10 mild, 11-14 moderate, 15-21 severe.
Time frame: 5 years
Body image
Body image will be measured with the Multidimensional Body-Self Relation Questionnaire (MBSRQ).Multidimensional body-self relations questionnaire- appearance scales.It is a 34-item self-report questionnaire designed to measure appearance related components of body-image. In consists of five subscales: appearance evaluation, appearance orientation, body areas satisfaction, overweight preoccupation, and self-classified weight. It is a 5-point Likert-scale ranging from 1 to 5.
Time frame: 5 years
Body investment
Body investment will be measured with the Appearance Schemas Inventory-revised (ASI-R).Appearance schemas inventory-revised: is a 20-item self-report questionnaire designed to measure body-image investment. It consists of two subscales, self-evaluative salience (SES) and motivational salience (MS). It is a 5-point Likert-scale ranging from 1 (strongly disagree) to 5 (strongly agree). Twelve items relate to SES and eight items relate to MS. The total score is the mean of the 20 items, and the score of the subscales is the mean of the items relating to each subscale. A high score indicates greater body-image investment.
Time frame: 5 years
Generic quality of life
Generic quality of life will be measured with EuroQoL-5 dimensions (EQ-5D-3L).n EQ-5D-3L, the five dimensions each have three response levels of severity.Respondents are asked to choose the statement in each dimension that best describes their health status on the day they are surveyed. Their responses are coded as a number (1, 2, or 3) that corresponds to the respective level of severity: 1 indicates no problems, 2 some problems, and 3 extreme problems.
