BREAST cancer-related lymphedema surgery should reflect whether arm swelling is driven by fluid or fibrofatty tissue. A narrative review of delayed lymphatic reconstruction sets out how disease stage, tissue composition, and remaining lymphatic function can guide treatment after breast cancer care.
Breast cancer-related lymphedema can emerge months or years after treatment. The review cites estimated rates of approximately 5% after sentinel lymph node biopsy, 14% after axillary lymph node dissection alone, and 33% after axillary dissection combined with radiation therapy. Patients may report heaviness, tightness, pain, weakness, or persistent arm swelling.
Before attributing new or worsening swelling to lymphedema, clinicians should assess for cancer recurrence, deep vein thrombosis, infection, and other potential causes. Treatment history matters: taxanes can cause transient swelling, and other systemic therapies may contribute to peripheral edema. Limb measurements and, when indicated, lymphatic imaging help establish the diagnosis and identify the fluid and tissue changes that shape surgical planning.
Complete decongestive therapy, compression, pump treatment, and skin care remain the foundation of management. Surgery may be considered when symptoms persist despite appropriate conservative care, but it does not eliminate the need for ongoing lymphedema treatment.
For fluid-predominant swelling with functional lymphatic channels, lymphovenous bypass connects lymphatic vessels to small veins to improve drainage. Vascularized lymph node transfer offers another physiologic option when few usable channels remain; recurrent cellulitis may also favor this approach.
As disease progresses, fibrosis and fatty tissue can account for more of the excess limb volume. Lymphatic-sparing liposuction targets this fibrofatty burden, while direct excision is generally reserved for severe disease when less invasive approaches are unsuitable. Patients with both fluid and fibrofatty changes may undergo staged or combined procedures. Compression remains particularly important after liposuction to maintain volume reduction.
The review presents these choices as a clinical framework, rather than a comparison proving one operation superior. Differences in patient selection, outcome measures, and follow-up across existing studies limit direct comparisons. Prospective studies with standardized limb-volume and patient-reported outcomes are needed to clarify which procedures, combinations, and sequences provide durable benefit.
