PEROPERATIVE LOCALIZATION OF METASTASES W ITH A HAND-HELD GAMMA-PROBE

A 50-y-oid male patient with prostate cancer showed two suspicious les ions in bone scintigrams. They were assessed to be bone metastases by biopsy of the os ilium. After i. v, injection of Tc-99m-HMDP a probe-g uided localization permitted optimal surgical treatment. A bone metast asis in the os ilium was confirmed. The intraoperative detection with a hand-held gamma probe permitted accurate and complete excision of th e tumour; the bone defect could thus be reduced to a minimum.
