Early arm swelling after breast surgery: changes on both sides.

INTRODUCTION

Lymphedema is a common complication of treatment for breast cancer. However, little information is available describing changes in upper limb volumes in the early stages following surgery.

STUDY DESIGN

Retrospective audit.

PARTICIPANTS

Women who underwent unilateral mastectomy or axillary node removal for breast cancer at the Princess Alexandra Hospital, Brisbane, Australia.

MEASUREMENTS

Circumferential measurements taken at 10 cm intervals from the ulnar styloid on each arm were converted to segmental volumes using the frustum approach.

PROCEDURE

Pre-surgery baseline measures were taken by a physiotherapist at Preadmission Clinic at the Princess Alexandra Hospital. Follow-up measures were taken 6 weeks after surgery by Domiciliary Allied Health Acute Care and Rehabilitation Service physiotherapists in patients' homes.

RESULTS

Limb segment volumes increased in the proximal upper limb segments at follow-up. The proportion of patients with a 10% or greater increase in volume in one or more segments of their upper limb were similar for ipsilateral (35%) and contralateral (32%) sides (to side of surgery), respectively. No significant interaction between time and arm (ipsilateral versus contralateral) was identified.

DISCUSSION

These findings demonstrate that limb segment volume changes affect a greater proportion of patients during the first 6 weeks following surgery than previously recorded. They also indicate that flow of lymph from the side of surgery to the contralateral side may disperse lymph between sides during this early post-operative period. This has implications for how swelling is measured during this period and strategies to prevent onset of lymphedema.
