Abstract

BACKGROUND: Sentinel lymph node detection was investigated in dogs with spontaneously occurring tumours.
MATERIAL AND METHODS: In this pilot study, 24 client-owned spontaneously tumorous dogs presented for sentinel lymph node detection. A multiple method was used with a nuclear medicine technique (injection of 99mTc human serum albumin colloid) with scintigraphy and intraoperative guidance, and blue dye injection.
RESULTS: Of the 35 lymph nodes histologically demonstrated to contain metastases, 34 (97%) were found by radioguided surgery, which means that one would have been missed in the intraoperative localisation process; 31 nodes (89%) were clearly visualised in the gamma camera images; only 27 (77%) were blue-stained by vital dye; a mere 8 lymph nodes (23%) were enlarged and therefore easily detectable by palpation.
CONCLUSIONS: Data obtained from the harmless application of the sentinel node concept are useful for the radiopharmaceutist. The sentinel lymph node concept is well applicable in the veterinary clinic.
