Treatment of carcinoma of base of tongue with radiation therapy and 5-fluorouracil. Potential for optimization with 18F-FU.

Abstract

The treatment of advanced base of tongue carcinoma with concurrent radiation therapy and 5-fluorouracil versus radiation therapy alone is compared. Although the results are inconclusive, it is noteworthy that all the 5-year survivors were patients given combined treatment. Important questions regarding optimization of time-dose relationships with combined therapy were generated. Accordingly, 18F-5 fluorouracil was synthesized in an attempt to answer some of these questions.
