The aim of this study was to describe our preliminary experience in the use of radioguided surgery for the detection of sentinel nodes (SN) and hyperfunctioning parathyroid glands. We studied 10 patients: Eight for the detection of SN (7 patients with primary melanoma and one patient with vulvar cancer), and two patients with secondary hyperparathyroidism (SHP) for the resection of hyperfuntioning glands. We used for both groups of patients an intraoperative gamma probe equipped with a CdTe detector (Gammed II, Eurorad). A dose of 250-450 µCi of Tc-99 Re-nanocolloid and of 10 mCi of Tc-99m MIBI was employed, 4-6 hours and 2 hours before surgery respectively. During surgery, one SN was identified corresponding to 9/10 primary melanomas and 2 GC corresponding to the vulvar lesion. In the group with SHP the hyperfuntioning parathyroid glands were clearly detected. We conclude that radioguided surgical techniques are technically feasible and clinically relevant surgical tools.
