Sentinel nodes scintigraphy of the internal mammary chain in breast cancer

Internal mammary chain lymphnodes (IMNs) were studied by lymphoscintigraphy and biopsy in 100 breast cancer patients to assess: a deep injection can visualize the IMNs in a high percentage of cases o determine how often IMNs are metastatic. han 60% of patients showed IMNs uptake. Surgical sampling proved simple and risks insignificant. Five positive IMN cases migrated from NO/N1 to N3, prompting treatment modification. It is unclear whether this additional information can lead to better survival.
