57Co-bleomycin scintigraphy in staging of carcinoma of the cervix

65 patients with cervical cancer at various stages of the disease were studied scintigraphically after 57Co-bleomycin administration, active urine being flushed out from the bladder continuously. The patients were submitted to other auxiliary tests and the interpretation of scintigraphic images could thus be verified. Scintigraphic data were classified semiquantitatively by scoring in the range from zero to 5. Results were evaluated in terms of ROC-curves. This method of analysis permitted selection of cut-off levels for binary decisions that yielded satisfactory sensitivity and acceptable specificity of the test.
