โฆ Synopsis
T sively as a contrast medium since its introduction by Bluhbaum et al.5 in 1928. Shortly thereafter, Radtll described its use in hepatosplenography. The commercial preparation, known as Thorotrast, is a 24 to 26% colloidal suspension of thorium dioxide with dextrin as a stabilizer and hydroxybenzoate (0.15oj',) as the preservative. The particle size averages about 15 p. Thorium ( Th232) is an alpha emitter with a half life of 1 . 3 9 ~1 0 ~~ years and 11 daughter isotopes that emit alpha, beta, and gamma rays of varying energy. The decay pattern has been described by Rotblat and Ward.l2

Cytotoxic chemotherapy has an evolving role in the management of metastatic cancer of the bladder and urinary tract. The most responsive of these tumors are transitional cell carcinomas. Standard single agents (e.g., methotrexate, doxorubicin, mitomycin, ifosfamide, vinblastine, and cisplatin) have
Patients with metastatic non-seminomatous testicular cancer can be cured by cisplatin-based chemotherapy. After chemotherapy, surgical resection is a generally accepted treatment to remove remnants of the initial metastases since residual tumor may still be present (mature teratoma or viable cancer
We have developed a liver metastatic model of human colon cancer using severe combined immunodeficient (SCID) mice. Liver metastases were observed in all the SCID mice on day 28 after intrasplenic injection with 5 X lo6 dissociated tumor cells of COL-2-JCK, a human colon cancer strain serially trans
