EFFECT OF GALLIUM NITRATE THERAPY ON GA-67 SCINTIGRAPHIC DETECTION OFLYMPHOMA - CASE-REPORT

Ga-67 and abdominal CT scans of a 72-year-old woman who had malignant lymphoma before, during, and after gallium nitrate/hydroxyurea combina tion therapy are presented. Disappearance of Ga-67 uptake by the tumor during this treatment despite continuing CT evidence of disease and r eappearance of Ga-67 scan abnormalities after cessation of therapy sug gests that caution should be exercised when interpreting results of Ga -67 scintigraphy for the detection of tumor viability during gallium n itrate/hydroxyurea therapy.
