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.
Method
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.
