title: Role of nuclear medicine in chemotherapy of malignant lesions.
abstract: The major role of nuclear medicine in clinical oncology is in tumor imaging, which includes evaluating specific organs or the entire body for the presence of tumor. Nuclear medicine studies have been used clinically in the initial evaluation of the tumor extent and in the subsequent management of the cancer patient to assess response to treatment, to detect early relapse, and to assist in making decisions concerning follow-up treatment. Technetium-99m macroaggregated albumin perfusion study for intraarterial chemotherapy has been helpful in monitoring the catheter tip, providing a map of regional perfusion at the capillary level (tumor vascularity), evaluating the degree of arteriovenous shunt in tumor bed, and optimizing division of the dose of chemotherapeutic agent when bilateral arterial catheters are used. Quantitative and serial radionuclide angiocardiography has been useful in assessing doxorubicin (Adriamycin, Adria Laboratories, Columbus, Ohio) toxicity, and 67Ga-citrate imaging has been used to monitor chemotherapy effect on lungs and kidneys. Radionuclide venography can demonstrate suspected thrombus, and the delineation of the vascular anatomy also allows proper placement of another catheter for continuous effective chemotherapy. Serial bone scans have been the primary modality to assess the response of bone metastasis to systemic therapy in breast cancer patients, and nuclear hepatic imaging may show tumor response, hepatocellular dysfunction, and cholecystitis related to chemotherapeutic agents.(ABSTRACT TRUNCATED AT 250 WORDS)
