BackgroundBreast cancer is the most common type of cancer in women in the developed world. As a result of breast cancer treatment, many patients suffer from serious complaints in their arm and shoulder, leading to limitations in activities of daily living and participation. In this systematic literature review we present an overview of the adverse effects of the integrated breast cancer treatment related to impairment in functions and structures in the upper extremity and upper body and limitations in daily activities. Patients at highest risk were defined.Methods and FindingsWe conducted a systematic literature search using the databases of PubMed, Embase, CINAHL and Cochrane from 2000 to October 2012, according to the PRISMA guidelines. Included were studies with patients with stage I–III breast cancer, treated with surgery and additional treatments (radiotherapy, chemotherapy and hormonal therapy). The following health outcomes were extracted: reduced joint mobility, reduced muscle strength, pain, lymphedema and limitations in daily activities. Outcomes were divided in within the first 12 months and >12 months post-operatively. Patients treated with ALND are at the highest risk of developing impairments of the arm and shoulder. Reduced ROM and muscle strength, pain, lymphedema and decreased degree of activities in daily living were reported most frequently in relation to ALND. Lumpectomy was related to a decline in the level of activities of daily living. Radiotherapy and hormonal therapy were the main risk factors for pain.ConclusionsPatients treated with ALND require special attention to detect and consequently address impairments in the arm and shoulder. Patients with pain should be monitored carefully, because pain limits the degree of daily activities. Future research has to describe a complete overview of the medical treatment and analyze outcome in relation to the treatment. Utilization of uniform validated measurement instruments has to be encouraged.

Measurement instruments with evidence for good reliability and validity were BIS, water volumetry, tape measurement, and perometry, where BIS can detect alterations in extracellular fluid in stage 1 lymphedema and the other measurement instruments can detect alterations in volume starting from stage 2. In research, water volumetry is indicated as a reference test for measuring lymphedema in the upper extremities.

The ICF provides a valuable reference to identify concepts in questionnaires focusing on individuals with lymphedema. Implications for Rehabilitation Lymphedema is a chronic condition and the problems in physical functioning related to lymphedema can result in distress and loss of quality of life. ICF Core Sets for lymphedema consist of a lymphedema-specific selection of ICF categories, which makes it easier to implement the use of the ICF in medical and allied health care. ICF Core Sets for lymphedema can act as a framework for more unity in questionnaires concerning consequences of lymphedema. Part of the development process of ICF Core Sets for lymphedema is the linking of items from lymphedema-specific clinical questionnaires to ICF codes. The ICF codes most frequently used to link the items in the reviewed questionnaires were "Structure of upper extremity", "Immunological system functions", "Looking after one's health", "Sensation of pain", "Touch functions", "Dressing" and "Health services, systems and policies".

Circumference difference between arms of 4% measured at 30 cm proximal to the styloid process can be used as a surveillance site for further monitoring of patients at risk for lymphedema and may contribute to early diagnosis. Feelings of heaviness or swelling have moderate relationship with lymphedema, which needs to be confirmed in clinical practice.
