The use of cytokines in head and neck cancer is increasingly under inv
estigation. Clinical trials have tested the interferons, interleukin-2
and other cytokines as single agents and in various combinations. The
addition of interferon to the cisplatin and 5-fluorouracil (5-FU) reg
imens (with and without leucovorin) has been explored. A randomized in
ternational trial comparing cisplatin and 5-FU with cisplatin, 5-FU an
d interferon-alpha 2b is in progress.
