title: [Responses of tumor cell lines and surgical specimens transplanted into chorioallantoic membrane of chick embryo to anticancer agents in combination with/without hyperthermia].
abstract: The chorioallantoic membrane of chick embryo was used to examine the responses of tumor cell lines and surgically resected specimens to anticancer agents in combination with or without hyperthermia. B16-F10 melanoma, KK-47 cell line derived from a transitional cell carcinoma of the bladder and surgical specimens from urological malignancies were transplanted onto the chorioallantoic membrane of chick embryo 10 days after fertilization. The effects of intravascularly injected cyclophosphamide, cisplatin, adriamycin, mitomycin C, vincristine and vinblastine, in combination with or without hyperthermia, on the growth of the grafts were investigated. A 15-minute 42.5 degrees C hyperthermia exhibited most favorable anticancer effects in B16-F10 grafts (P less than 0.01) of all heating conditions tested. A combined use of hyperthermia and cisplatin, cyclophosphamide or adriamycin demonstrated a significantly high tumor regression rate in B16-F10 grafts (P less than 0.01). In KK-47 grafts, a single use of cyclophosphamide and a combined use of hyperthermia and cyclophosphamide exhibited a highly significant antitumor regression (P less than 0.05). Surgical specimens from 14 urological malignancies were subjected to this assay. Growth which was adequate for sensitivity test was obtained in 11 of the 14 malignancies. The results obtained suggest that this assay system may be a useful chemohyperthermia sensitivity test.
