title: A rapid in vitro assay for predicting thermochemosensitivity of human cancer: comparison with clonogenic assay.
abstract: We previously reported a rapid in vitro assay based on morphological changes in the nucleus in order to predict response to thermochemotherapy. It was strongly suggested that this simple method may be clinically useful. In the present study, a comparison with the clonogenic assay was carried out on eight different human tumors (three malignant melanomas, two lung carcinomas, two colon carcinomas and one leukemia). Melphalan, mitomycin C and vincristine were tested. Correlation between the two test systems was dependent upon the criteria for each test system. At the level of less than 50% survival of colony as compared with normothermic dishes in clonogenic assay, there was a high correlation between the two test systems for sensitive tumor to 43 degrees C. In respect of response to thermochemotherapy, when only karyorrhexis changes in the nucleus were selected as an activity criteria in our cytotoxic test, parallel data between the two test systems were obtained.
