The purpose of this study is to investigate whether a training program with intensified physical exercise prior to and after surgery for breast cancer enhances postoperative recovery.
This study is designed as a randomised, controlled, non-blinded multicenter trial with two parallell study groups, intervention and control. The primary endpoint of recovery is measured within 12 months after surgery.
After randomisation, participants in the intervention group will be scheduled for an individual consultation with the physiotherapist, where the are advised to increase their Daily physical activiy level with an additional 30 minutes. The added physical activity is registered in an exercise diary daily.
All included participants will be asked to complete questionnaires at inclusion (I), 4 weeks (+/- 1 w) postoperatively (II) and 12 months (+/-1 month) postoperatively (III).
Data regarding patient characteristics, surgical details, postoperative events, complications according to Clavien - Dindo and additional treatment will be collected using eCRF: (I) 30 Days postoperatively, (II) 90 days postoperatively and (III) 12 months postoperatively. Data will also be retrieved from the Swedish National Breast Cancer Register, the Swedish Social Insurance Agency and the Swedish National Death Register.
Patrticipants who wish to be excluded from the study will be asked if already collected data may be analysed in the study.
The code for the study cohort will include personal identity as well as a study specific code. This is placed on a server, with limited access, at Sahlgrenska University Hospital. The database is placed on a server within the University of Gothenburg system accessible with username and code. The database includes only the study specific code for each participant. Data from questionnaires will be entered manually. Length of hospital stay will be acquired from the hospital registries and then entered manually into the database. Data from CRF (I-III) will be entered in the same database, as well as data retrieved from the Swedish National Breast Cancer Register, the National Death Register and Swedish Social Insurance Agency.
In all a high security standard with automatic back up of server data is present as well as firewalls against external violation. A data manager, employed by the SSORG unit will be responsible for the database.
The investigators plan to perform an interim analysis for the first 100 patients included, in order to make a more exact estimate of the power needed. An external monitoring committee will be appointed for the interim analysis, and the question to the committee will be limited to a recalculation of cohort size.The participants will be analysed according to randomisation (intention to treat-type of analysis).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Physical activity | Experimental | Individual consultation with a physiotherapist in order to increase the participants existing level of physical activity by adding 30minutes of physical activity daily, preoperatively and 4 weeks postoperatively. |
|
| Control | No Intervention | Participants randomized to the control group will not be advised to change their current level of physical activity. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Physical activity | Behavioral | Preoperative intervention - takes place from randomization until surgery (4 weeks +/-2 w): • 30 minutes of exercise daily added to the existing daily exercise routine. The level of exercise should produce shortness of breath but the patient should be able to talk without much effort. Postoperative intervention - takes place from discharge from the hospital until 4 weeks postoperatively: • 30 minutes of exercise daily added to the existing daily exercise routine. The level of exercise should produce shortness of breath but the patient should be able to talk without much effort. Participants randomized to intervention will receive a visit to a physiotherapist for personally adjusted information regarding the intervention, later followed up with a telephone call. |
