A comparison of 111In-octreotide and 67Ga scintigraphy in malignant lymphoma.

We compared 111In-octreotide and 67Ga scintigraphy for staging malignant lymphoma. In 11 patients, planar imaging was performed 4 and 24 h after the injection of 111In-octreotide and 48 and 72 h after the administration of 67Ga. Radiological and clinical data were used as the 'gold standard', resulting in the identification of 26 lesions.

[Is jaundice a cause of error in the interpretation of CA 19-9 blood levels?].

Serum CA 19-9 has been proposed as a tumour marker for pancreatic cancer (PC). However, false positive results are seen in sera of patients with benign jaundice. The CA 19-9 assay was performed by a solid state radioimmunoassay in 86 icteric patients (total bilirubin greater than 2 mg/dl).
