Abstract
OBJECTIVES: To assess the feasibility of ultrasound and shear wave elastography (SWE) in the diagnosis of breast cancer-related lymphedema. METHODS: Forty-one patients with a history of unilateral breast surgery and axillary dissection or sentinel lymph node excision were included in this prospective study. The patients were classified as having normal findings, latent lymphedema, and clinical lymphedema on the basis of a physical examination, lymphedema index scores, and limb circumference measurements. The thickness and stiffness of the cutaneous and subcutaneous tissue of the forearm and arm were measured by ultrasound and SWE. The thickness and stiffness of the cutaneous and subcutaneous tissue of the affected limb and contralateral limbs of the normal, latent lymphedema, and clinical lymphedema groups were compared. RESULTS: The mean age ± SD of the 41 patients was 55.42 ± 10.12 years. There were 15 patients with normal findings, 10 with latent lymphedema, and 16 with clinical lymphedema. In the latent lymphedema group, the thickness measurements of the cutaneous tissue of the affected forearm and the cutaneous and subcutaneous tissue of the affected arm were significantly greater than those of the contralateral forearm and arm (P = .034; P = .022; and P = .002, respectively), and the stiffness measurements of the cutaneous and subcutaneous tissue of the affected forearm were significantly greater than those of the contralateral forearm (P = .011; and P = .002). In the clinical lymphedema group, the thickness and stiffness measurements of the cutaneous and subcutaneous tissue of the affected forearm and arm were significantly greater than those of the contralateral limb (P < .001-P = .032). CONCLUSIONS: Ultrasound and SWE are effective for diagnosing breast cancer-related lymphedema even at a latent stage.
