Physical Rehabilitation After Breast Cancer
Breast cancer is ranked the top in types of cancer that affects Singaporean women8. It affects up to 1-in-13 women during their lifetime4. Moreover, disease-free survival after diagnosis and treatment of breast cancer has been reported as between 63%-74% at 10 years, with an overall survival rate of 63-86%5. As a reult, the focus of rehabilitation has shifted to optimise the quality of care and survival, as well as the quality of living of women diagnosed with breast cancer.
Types of breast cancer intervention include surgery, radiotherapy, chemotherapy & hormone therapy. A number of surgical procedures (Table 1) may be performed depending on the clinical presentation & histological results.
Table 1: Summary of surgical procedures for breast cancer
|Breast biopsy (lumpectomy)||Excision of a breast lump|
|Breast conservation (wide local excision; quadrantectomy; tylectomy; partial mastectomy)||Excision of tumour & surrounding breast tissue to give an adequate surgical margin from cancer cells. Axillary dissection performed in conjunction|
|Axillary dissection||Removal of lymph nodes|
|Simple mastectomy||Excision of all the breast tissue|
|Modified radial mastectomy (Patey)/MRM||Excision of all the breast tissue, axillary dissection & pectoralis minor muscle|
|Radial Mastectomy (Halsted)||As for modified radial mastectomy with the excision of pectoralis major muscle|
|Extended radial mastectomy||As for radial mastectomy with the excision of the underlying chest wall(ribs); a split skin graft is required to cover the surgical defect on the chest wall|
|Breast reconstruction (implants or myocutaneous flap|
Morbidity of primary breast cancer management
The aim of breast cancer treatment is to eradicate local disease & control the development of the disease – enhancing the survival of women diagnosed. However, there are potential problems such as:
- Decreased shoulder movement & function secondary to axillary dissection; radical procedures; or fibrosis after radiotherapy.
- Wound infection & delayed wound healing in the early postoperative period.
- Seroma development on the anterior chest or axilla after wound drains are removed.
- Lymphoedema of the arm &/ or breast secondary to surgical removal of or radiation damage to axillary lymph nodes & remaining breast tissue.
- Neural disorders including,
- Sensory disturbances in the medial upper arm due to the dissection of the intercostobrachial nerve;
- Nerve entrapment in the arm
- Fibrosis of the skin & muscle of the chest wall after radiotherapy.
- Psychological effects
- Local recurrence or metastatic spread of breast cancer.
Physiotherapists play a significant role in the identification, prevention &/or management of the above mentioned, and also assist in the support of women before, during & after the treatment and follow-up period for breast cancer.
Physiotherapy is recommended, in accordance with the surgeons’ preferences for post-operative care, to improve the physical recovery of women after breast cancer surgery. This is done through providing appropriate exercise prescription, and assist in the education of women after breast cancer surgery to facilitate their:
- Recovery of shoulder range of motion (ROM) and physical function of the operated arm;
- Awareness of lymphoedema, its prevention and early detection.
A planned approach to the physiotherapy management of women after breast cancer surgery with the ability to individualised exercise and education programmes is essential to ensure optimal quality of care and best practice.
Aims of physiotherapy management
- Regain patient’s preoperative shoulder ROM & function within three months of surgery;
- Maintain ROM overtime after surgery
- Patient education- knowledge of lymphoedema, its prevention and awareness of its early signs;
- Minimise the effect of developing secondary complications on their ultimate recovery.
Shoulder Range of Motion and Function
Early commencement of shoulder physiotherapy intervention after axillary dissection for breast cancer aids in the physical recovery of the patient. Nevertheless, the intervention is dependent upon each surgeon’s preference and protocol, and also issues of wound drainage, seromas, shoulder stiffness, complications and length of hospital stay. A physiotherapy management care plan (PMCP) (shown in Table 2) has been developed from literature and extensive clinical practice1, to help facilitate the recovery of women after breast cancer surgeries.
Table 2: shows a detailed general physical rehabilitation and management care plan for mastectomy.
|Physiotherapy Management Care Plan|
|PREOPERATIVE VISIT||Assessment – shoulder ROM, functional questionnaire, limb size|
Education – post-operative presentation & Exercises, preliminary lymphedema education
|DAILY POST OPERATIVE VISITS||Hand/elbow exercises – start immediately|
Shoulder movement- if no axillary dissection has been performed, start immediately post-op & progress within discomfort to full ROM; if axillary dissection has been performed, start at surgeon’s request or when wound drainage is < 100ml/24 hours or there is a marked decrease in drainage over 24 hour period; restricted to < or equal to 100 degrees for first 2 days of movement and gradually increase ROM using a limit of a discomfort rating of 3/10
Lymphedema prevention education progress as appropriate for each patient
|DISCHARGE FORM HOSPITAL||Review home programme and limitation of activities initially, re-measure shoulder ROM, functional questionnaire and limb size.|
|1 MONTH POST-OP||Progress exercises and stretches, advise on functional activity progressions, lymphedema prevention education, re-measure shoulder ROM, functional questionnaire and limb size.|
|2 MONTHS POST-OP||Assess effects of therapy and modify or progress exercises/ stretches. Advise return to pre-operative function & activity levels.|
|FOLLOW-UP AT 3,6,12,18,24 MONTHS||Assess progress with measurement of shoulder ROM, functional questionnaire and limb size. Modification of exercises as appropriate.|
Other studies, such as Wingate7,8, found that women who received physiotherapy from Day 1 post-op had better outcomes in terms of shoulder ROM & Function but there was an increase in arm swelling. However, at 3 months post-op, the amount of swelling was insignificant. These findings were later repeated in a study by Wingate et al8. Gutman et al2 found that women who underwent wide local excision and axillary dissection with radiotherapy achieved their pre-operative ROM faster than those who had an MRM but all regained normal ROM within 3 months post-op. Therefore, these authors recommend that while both groups require physiotherapy, the MRM group required more intensive and longer treatment.
Physiotherapy Management Care Plan
The principles of exercise after breast cancer surgery are:
- Assisted movements initially
- Slow & rhythmical
- Sustained movements & stretches incorporated after 14-21 days
- Limiting point is a discomfort (not pain)
- Care with the vigour of exercises performed to minimise interference with the regeneration of lymphatic channels
- Scar massage may be required to facilitate movement
- Continued intervention 6-12 months post-op as soft tissues continue to remodel and contract during this period
- Gradual progression of the type, duration and repetition of exercises with a warm-up and cool down.
