The Risk of Lymphedema After Breast Cancer Surgery Should Not Restrict Necessary Hand Surgery Interventions

The purpose of this study was to evaluate the incidence of lymphedema onset or exacerbation in patients undergoing upper extremity interventions, both nonoperative and operative, after breast cancer surgery.

The study inclusion criteria were the following: (1) prior history of breast cancer surgery or lymphedema from the cancer; (2) upper extremity intervention, ipsilateral to the breast cancer side; and (3) follow-up of at least 1 month. Patients were evaluated for demographic information, type of breast cancer procedure and hand intervention, number of lymph nodes dissected, preexisting lymphedema, exacerbation of lymphedema, and new-onset lymphedema.

A total of 161 patients undergoing 385 hand interventions (300 injections, 85 surgeries) were reviewed. Median follow-up was 31 months (range: 1-110). Nineteen patients had preexisting lymphedema ipsilateral to the hand procedure and none experienced an exacerbation of their lymphedema. Three patients developed new-onset lymphedema ipsilateral to their hand intervention at an average follow-up of 30 months (range: 4-67). One patient had a single injection and developed lymphedema over 5 years later. One had 2 injections in the same hand on the same date and developed lymphedema 3 months later. The third patient had 2 injections in the right hand, 1 injection and 1 surgery in the left hand, and developed either lymphedema or swelling due to rheumatoid arthritis in the right hand 1 year after the injections.

Patients who have undergone breast cancer surgery can safely undergo upper extremity intervention with low risk of lymphedema exacerbation or onset.
