Description
Rui Chen and colleagues test, in a 2026 prospective cohort study, a simpler way to recheck armpit lymph nodes after drug treatment in breast cancer that had already spread to those nodes. Before treatment, the most suspicious node was injected with a carbon dye under ultrasound guidance; after treatment, surgeons removed only the stained nodes and then cleared the rest for verification.
All 159 patients had their marked nodes found at surgery. About forty-one percent had no cancer left in the armpit, and the method missed residual disease in about five percent of cases, inside the accepted safety limit in every subgroup. The dye technique is cheap and straightforward, offering hospitals an alternative to sentinel node procedures after chemotherapy.
