Locoregional PMRT is recommended for women with 4 or more positive axillary lymph nodes .
The role of PMRT in women with 1 to 3 positive axillary lymph nodes is unclear .
Locoregional PMRT is generally not recommended for women who have tumours that are less than 5 cm in diameter and who have negative axillary nodes .
OBJECTIVE To provide information and recommendations to assist women with breast cancer and their physicians in making decisions regarding the use of locoregional post-mastectomy radiotherapy ( PMRT ) .
OUTCOMES Locoregional control , disease-free survival , overall survival and treatment-related toxicities .
To reduce the risk of lymphedema , radiation of the entire axilla should not be used routinely after complete axillary dissection of level I and II lymph nodes .
The use of modern techniques in radiotherapy planning is recommended to minimize excessive normal tissue exposure , particularly to the cardiac and pulmonary structures .
Common short-term side effects of PMRT , including fatigue and skin erythema , are generally tolerable and not dose-limiting .
Severe long-term side effects , including lymphedema , cardiac and pulmonary toxicities , brachial plexopathy , rib fractures and secondary neoplasms , are relatively rare .
Clinical practice guidelines for the care and treatment of breast cancer: 11. Lymphedema.
OBJECTIVE To provide information and recommendations for women and their physicians when making decisions about the management of lymphedema related to breast cancer . OPTIONS Compression garments , pneumatic compression pumps , massage and physical therapies , other physical therapy modalities , pharmaceutical treatments . OUTCOMES Symptom control , quality of life , cosmetic results . EVIDENCE Systematic review of English- language literature retrieved primarily from MEDLINE ( 1966 to April 2000 ) and CANCERLIT ( 1985 to April 2000 ) . Non systematic review of breast cancer literature published to October 2000 . RECOMMENDATIONS Pre- and postoperative measurements of both arms are useful in the assessment and diagnosis of lymphedema . Circumferential measurements should be taken at 4 points : the metacarpal-phalangeal joints , the wrists , 10 cm distal to the lateral epicondyles and 15 cm proximal to the lateral epicondyles . Clinicians should elicit symptoms of heaviness , tightness or swelling in the affected arm . A difference of more than 2.0 cm at any of the 4 measurement points may warrant treatment of the lymphedema , provided that tumour involvement of the axilla or brachial plexus , infection and axillary vein thrombosis have been ruled out . Practitioners may want to encourage long-term and consistent use of compression garments by women with lymphedema . One r and omized trial has demonstrated a trend in favour of pneumatic compression pumps  compared with no treatment . Further r and omized trials are required to determine whether pneumatic compression provides additional benefit over compression garments alone . Complex physical therapy , also called complex decongestive physiotherapy , requires further evaluation in r and omized trials . In one r and omized trial no difference in outcomes was detected between compression garments plus manual lymph drainage versus compression garments alone . Clinical experience supports encouraging patients to consider some practical advice regarding skin care , exercise and body weight . [ A patient version of these guidelines appears in Appendix 2 . ] VALIDATION An initial draft of this document was developed by a task force sponsored by the BC Cancer Agency . It was up date d and revised substantially by a writing committee and then su bmi tted for further review , revision and approval by the Steering Committee for Clinical Practice Guidelines for the Care and Treatment of Breast Cancer . SPONSOR The steering committee was convened by Health Canada . COMPLETION DATE : October 2000
