Abstract
BACKGROUND
The incidence of breast cancer (BC)βrelated lymphedema (LE) ranges from 7% to 47%. Successful management of LE relies on early diagnosis using sensitive measurement techniques. In the current study, the authors demonstrated the effectiveness of a surveillance program that included preoperative limb volume measurement and interval postoperative followβup to detect and treat subclinical LE.
METHODS
LE was identified in 43 of 196 women who participated in a prospective BC morbidity trial. Limb volume was measured preoperatively and at 3βmonth intervals after surgery. If an increase >3% in upper limb (UL) volume developed compared with the preoperative volume, then a diagnosis of LE was made, and a compression garment intervention was prescribed for 4 weeks. Upon reduction of LE, garment wear was continued only during strenuous activity, with symptoms of heaviness, or with visible swelling. Women returned to the 3βmonth interval surveillance pathway. Statistical analysis was a repeatedβmeasures analysis of variance by time and limb (P β€ .001) comparing the LE cohort with an ageβmatched control group.
RESULTS
The time to onset of LE averaged 6.9 months postoperatively. The mean (Β±standard deviation) affected limb volume increase was 83 mL (Β±119 mL; 6.5% Β± 9.9%) at LE onset (P = .005) compared with baseline. After the intervention, a statistically significant mean 48 mL (Β±103 mL; 4.1% Β± 8.8%) volume decrease was realized (P < .0001). The mean duration of the intervention was 4.4 weeks (Β±2.9 weeks). Volume reduction was maintained at an average followβup of 4.8 months (Β±4.1 months) after the intervention.
CONCLUSIONS
A short trial of compression garments effectively treated subclinical LE. Cancer 2008. Published 2008 by the American Cancer Society.
