Abstract |
We performed 17 intraarterial scintigraphies in six
patients with recurrent cervix cancer. With Seldinger
method, the agent (four different radiopharmaceuticals)
was perfused at the same speed of infusion of
anticancer drugs (25 cc/hour) through internal iliac
artery. There were four different radiopharmaceuticals;
I-131-Lipiodol, Tc (Technetium)-99m-HSA (Human Serum
Albumin), Tc- 99m-Sucralfate and Tc-99m-MAA
(Macroaggraegated Albumin). We evaluate the
distribution pattern of radioactivity by the use of
ratio of Tumor/Extratumor uptake (T/ET ratio). Our
results reveals that Tc-99m-MAA scan showed the highest
T/ET ratio and the other were not ideal agents for
intraarterial therapy of recurrent cervix cancer. In
conclusion, an ideal radioisotope and tracer which can
block capillary, for example MAA, should be re-
evaluated or produced in order to treat the patient
with recurrent cervix cancer. |
