  • METHODS: Patients who underwent cALND following a positive SLN were analysed for histopathological features of the primary tumour and burden of axillary disease. (ox.ac.uk)
  • RESULTS: Of 155 patients, 115 (74%) had macrometastases and 40 (26%) micrometastases in the SLNs. (ox.ac.uk)
  • Residual axillary disease was detected in 55/155 (35%) patients with macrometastases and 4/40 (10%) with micrometastases. (ox.ac.uk)
  • CONCLUSION: Patients may be advised to forgo cALND where the SLN contains isolated tumour cells or micrometastasis. (ox.ac.uk)
  • Conclusions In our setting, SLNB using methylene blue dye is also an effective method for accurately identifying SLNs in breast cancer patients and provide an accurate pathological staging without having to do a formal axillary clearance. (bvsalud.org)
