Prevention of lymphoedema after axillary clearance by external compression sleeves PLACE randomised trial results. Effects of high BMI

Abstract Around 25% of women undergoing Axillary Clearance (ANC) develop lymphedema (LE). Intervention with a compression garment is recommended to prevent LE but no randomised evidence exists to support this strategy. Methods A randomised trial tested standard management versus application of graduated compression garments (20‐24 mmHg) to affected arm, for 1 year. Women with node positive breast cancer (n = 1300) undergoing ANC consented to arm volume measurements and those developing a 4–9% relative arm volume increase (RAVI) (subclinical LE) within 9 months post‐surgery were randomised. Primary outcome was proportion of patients developing LE (RAVI > 10%) by 24‐months in each group. Secondary endpoints included Quality of life in each group. Results In total 143 patients were randomised (74 no sleeve: 69 compression sleeve) between October 2010 and November 2015. The lymphoedema rate at 24 months in the ‘no sleeve’ group was at 41%, similar to the ‘sleeve’ group (30%: p = 0.32). Thirtytwo patients randomised to the ‘no sleeve’ group had a sleeve applied within 24 months. Body Mass Index (BMI) at randomisation predicted LE at any time point HR 1.04 (CI 1.01–1.08; p = 0.01). Patients with obesity (BMI > 30) had higher rates of LE in both groups (46%) compared to those with BMI 30. The use of prophylactic garments in subclinical LE (RAVI
