In the use of hyperthermia treatment, it is apparent from the work of other investigators that only a proportion of large clinical neoplastic tumors of substantial size and deep location can be heated to adequate temperatures (over 42 degrees c). It is therefore of major significance that we have tested the concept that OK-432 can be used as an immunoheat potentiator. A ThermaTech 2000 was used as the radio-frequency generator at 13.56 MHz, including an ancillary computer in the thermometry unit. Minor response in advanced and metastatic tumors was observed in 3 of 3 evaluable patients using OK-432. With other anticancer drugs, no change was observed in 11 of 16 patients, and progressive disease in 5 of 16. However, OK-432 has severe side effects including chills & fever, therefore improved immunoheat potentiators are desirable.
