Brief Summary

In breast cancer patients late-term upper limb sequelae, such as shoulder pain and impaired shoulder function remain common after primary breast cancer surgery. The aim of this trial is to evaluate whether an expert assessment of shoulder impairments, followed by an individualised treatment plan, is superior to a minimal physiotherapeutic rehabilitation program in reducing shoulder symptoms, assessed 12 weeks after initiation of treatment, among women with late-term shoulder impairments after primary breast cancer surgery.

Detailed Description

Worldwide, breast cancer is the second most common cancer. Internationally, an age-standardised incidence rate between 83.1 and 111.9 per 100.000 women is seen, with Denmark taking an unfortunate second place. Standard surgical treatment in Denmark is breast-conserving surgery (BCS) or mastectomy in combination with sentinel lymph node dissection (SLND) or axillary lymph node dissection (ALND). In part due to early diagnosis and optimised treatment methods, 5-year survival has improved to a current 87%. Despite fewer mastectomies and more BCS, less invasive surgical procedures of the axilla (e.g. fewer ALND vs. SLND), and more refined radiotherapy procedures, late-term upper limb impairment still remains common. The most frequent are lymphoedema, sensory disturbances, pain and impaired shoulder function, with up to 70% of patients reporting at least one of these symptoms three years after surgery. These impairments lead to difficulties in activities of daily living, increased risk of depression and anxiety and decreased quality of life (QoL).

Previous research has primarily focused on prevention and treatment of lymphedema, and less on other upper limb impairments. Pre- and early postoperative physiotherapeutic interventions are known to be effective in reducing shoulder pain and improving shoulder function after breast cancer treatment. Nonetheless, late-term upper limb impairments need further focus with prevalence´s of up to 50% is reported for impaired shoulder function and pain up to 6 years after surgery, and a substantial knowledge gap exists as to how to help these women. Currently, no standardised evaluation of their impairments or treatment is offered, and it is therefore up to the individual woman to seek care, resulting in large variations in rehabilitation. Thus a substantial knowledge gap exists in how to meet the rehabilitation needs of these women and evaluation of the actual burden of late-term shoulder impairments after primary treatment for breast cancer and the effect of different treatment strategies is warranted.

The primary aim of this study is to investigate whether the effect of a patient-centred specialised intervention, consisting of an expert assessment followed by an individualised treatment plan (i.e. Intervention group), is superior to a minimal physiotherapeutic rehabilitation program delivered in a pamphlet (i.e. Control comparator group) among women with late-term shoulder impairments 3-7 years after their primary breast cancer surgery. The hypothesis is that women randomised to the Intervention Group will improve significantly more in shoulder function and pain 12 weeks after initiating the treatment than those randomised to the Control comparator group.

This trial is a stratified (by type of surgery and radiotherapy), block randomised (1:1 allocation), controlled, parallel group and assessor blinded superiority trial conducted in Denmark. 130 participants with late-term shoulder impairments 3-7 years after primary surgery for breast cancer will be recruited.

Primary Outcome Measures

Name	Time	Method
Change in Shoulder Pain and Disability Index (SPADI) from baseline to 12 weeks after initiating the treatment.	0, 4, 8 and 12 weeks	SPADI is a 13-item patient-reported outcome measure to assess shoulder pain (5 items) and shoulder function (8 items) within the last week. The items are scored on a numeric rating scale that ranges from 0 (no pain/no difficulty) to 10 (worst pain/so difficult that required help). Each domain score is equally weighted and added to a total percentage score that ranges from 0 (best) to 100 (worst). The higher the score, patients reported shoulder impairments. The region specific questionnaire can be used in patients with different or unspecified shoulder diagnoses. SPADI is valid, reliable and responsible measure among patients with shoulder impairments.

Secondary Outcome Measures

Name	Time	Method
Change in SPADI pain from baseline to 12 weeks after initiating the treatment.	0, 4, 8 and 12 weeks	Change in SPADI pain will be reported as a separate subscale. The 5-item pain subscale are scored on a numeric rating scale that ranges from 0 (no pain) to 10 (worst pain). The higher the score, patients report greater shoulder pain and reduction in the SPADI pain score will suggest improvement.
Change in SPADI function from baseline to 12 weeks after initiating the treatment.	0, 4, 8 and 12 weeks	Change in SPADI function will be reported as a separate subscale. A 6-item version (exclusion of question three and seven) of the disability subscale exhibited adequate fit in the Danish version. The 6-item disability subscale are scored on a numeric rating scale that ranges from 0 (no difficulty) to 10 (so difficult that required help). The higher the score, patients report greater shoulder disabilities and reduction in the SPADI function score will suggest improvement.
Global Perceived Effect (GPE) measured at 4, 8 and 12 weeks after initiating the treatment.	4, 8 and 12 weeks	The GPE will evaluate the impression of the treatment's success including overall shoulder problems on a 7-point Likert scale ranging from "markedly worse" to "markedly improved".
Change in shoulder pain during general activities within the previous 24 hours in the affected shoulder measured by Numeric Rating Scale (NRS) from baseline to 12 weeks after initiating the treatment.	0, 4, 8 and 12 weeks	The NRS pain scale is a single 11-item patient reported outcome measure used to assess pain during general activities. The scale ranges from 0 (no pain) to 10 (worst pain imaginable). The higher the score, patients report greater shoulder pain and reduction in the NRS score will suggest improvement. The NRS is a reliable, valid and responsive measure of pain in patients with cancer.
Change in shoulder pain at rest within the previous 24 hours in the affected shoulder measured by Numeric Rating Scale (NRS) from baseline to 12 weeks after initiating the treatment.	0, 4, 8 and 12 weeks	The NRS pain scale is a single 11-item patient reported outcome measure used to assess pain at rest. The scale ranges from 0 (no pain) to 10 (worst pain imaginable). The higher the score, patients report greater shoulder pain and reduction in the NRS score will suggest improvement. The NRS is a reliable, valid and responsive measure of pain in patients with cancer.
SPADI clinical response.	12 weeks (follow-up)	Response to treatment will be computed for the SPADI change score for each woman in both treatment groups and presented dichotomised (i.e. responder and non-responder) as number (and percentages) responders. Women will be classified as an responder if the SPADI change score improves by 8 points or more (≥), corresponding to the minimal clinically important difference on SPADI from baseline to 12 weeks follow-up.
Change in maximum shoulder pain intensity within the previous 24 hours in the affected shoulder measured by Numeric Rating Scale (NRS) from baseline to 12 weeks after initiating the treatment.	0, 4, 8 and 12 weeks	The NRS pain scale is a single 11-item patient reported outcome measure used to assess the maximum shoulder pain intensity. The scale ranges from 0 (no pain) to 10 (worst pain imaginable). The higher the score, patients report greater shoulder pain intensity and reduction in the NRS score will suggest improvement. The NRS is a reliable, valid and responsive measure of pain in patients with cancer.
Change in shoulder pain assessment during flexion/rotation/abduction in the affected shoulder measured by Numeric Rating Scale (NRS) from baseline to 12 weeks after initiating the treatment.	0 and 12 weeks	The NRS pain scale is a single 11-item patient reported outcome measure used to assess pain during flexion/rotation/abduction. The scale ranges from 0 (no pain) to 10 (worst pain imaginable). The higher the score, patients report greater shoulder pain and reduction in the NRS score will suggest improvement. The NRS is a reliable, valid and responsive measure of pain in patients with cancer.
Change in Active Range Of Motion (A-ROM) in the affected shoulder from baseline to 12 weeks after initiating the treatment.	0 and 12 weeks	A smartphone inclinometer (GetMyROM) will be used to assess A-ROM in flexion, internal rotation, external rotation and abduction respectively the operated side. After one test trial, the mean value of three measurements will be taken for both flexion, rotation and abduction respectively the operated side.
Change in Passive Range Of Motion (P-ROM) in the affected shoulder from baseline to 12 weeks after initiating the treatment.	0 and 12 weeks	A smartphone inclinometer (GetMyROM) will be used to assess P-ROM in flexion, internal rotation, external rotation and abduction respectively the operated side. After one test trial, the mean value of three measurements will be taken for both flexion, rotation and abduction respectively the operated side.
Number of treatments received due to shoulder symptoms from baseline to 12 weeks after initiating the treatment.	12 weeks (follow up)	Number of visits to a healthcare professional (e.g. physician, chiropractor or physiotherapist) at hospital, municipality rehabilitation or private practice due to the shoulder symptoms during the intervention period, will be collected by using a patient-reported questionnaire.
Change in shoulder pain during sleep within the previous 24 hours in the affected shoulder measured by Numeric Rating Scale (NRS) from baseline to 12 weeks after initiating the treatment.	0, 4, 8 and 12 weeks	The NRS pain scale is a single 11-item patient reported outcome measure used to assess pain during sleep. The scale ranges from 0 (no pain) to 10 (worst pain imaginable). The higher the score, patients report greater shoulder pain and reduction in the NRS score will suggest improvement. The NRS is a reliable, valid and responsive measure of pain in patients with cancer.
