The tumoricidal activities of single dose x-irradiation (RAD) and concomitant Actinomycin D (AMD) with or without local tumor hyperthermia (LTH) on an in vivo Methylcholanthreme-induced fibrosarcoma (Meth-A) are described. The addition of LTH enhanced the actions of AMD, RAD and AMD + RAD; the
Hyperthermia is being tested as an adjuvant to chemotherapy for clinical use. We elected to study the interaction of heat at 43 degrees C with actinomycin D (AMD) (0.5 microgram/ml) in tissue culture using plateau phase Chinese hamster cells. The simultaneous administration of 43 degrees C and AMD
We investigated the possible mechanisms of hyperthermic enhancement of actinomycin D (AMD) cytotoxicity in a neoplastic cell line. The hyperthermic enhancement of AMD cytotoxicity depended on both the temperature and the sequence of the administration. The percentage survival of simultaneous
The incorporation of 3H-uridine into the RNA was studied under normothermia 37 degrees C/120 min, hyperthermia 42.5 degrees/120 min, and both in combination with Actinomycin D by an autoradiographic in vitro method in 19 solid tumors of children: 6 Wilms' tumors, 5 neuroblastomas, 4 osteogenic

The effect of hyperthermia on the activity and the messenger RNA levels of ornithine decarboxylase (ODC), which has a rapid rate of turnover in cultured cells, was studied in Ehrlich ascites tumor cells. When the cells were incubated at 42 degrees C, elevation of ODC activity by a change of the
OBJECTIVE
To evaluate the efficacy and toxicity of a regimen of etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine in patients with metastatic, high-risk gestational trophoblastic tumors.
METHODS
Twelve women with metastatic gestational choriocarcinoma received 64 treatment
A tumor colony-forming assay was used to investigate the effect of 40.5 degrees C hyperthermia and drugs on the colony-forming ability of human clonogenic tumor cells. In order to be able to perform repeated incubations with identical tumor material, specimens were used that were augmented in the
Hepatopathy induced by vincristine, actinomycin D and cyclophosphamide (VAC) is a potentially lethal complication of VAC chemotherapy for pediatric malignancy, which is managed by conventional anticoagulation and liver-supporting treatment alone. We report a case of VAC-induced hepatopathy with
A total of 42 patients with stage IIB nonseminomatous germ cell tumors of the testis after orchiectomy and retroperitoneal lymph node dissection received adjuvant chemotherapy with the modified vinblastine, actinomycin D, bleomycin, cyclophosphamide and cis-platinum regimen. Of the patients 29 had
The effects of treatment with several antitumor agents in combination with hyperthermia (42 degrees and 43 degrees) on the cell survival of cultured mouse leukemia L5178Y and mammary carcinoma FM3A cells were studied by following clonal growth in a soft-agar medium. L5178Y cells were more
Embryonal tumors (21 Wilms' tumors, 11 neuroblastomas, 9 rhabdomyosarcomas) and 16 sarcomas of the skeleton of childhood were studied with an autoradiographic in vitro method according to the responsibility to hyperthermia 42.5 degrees C/120 min, to Cyclophosphamide, to Doxorubicin, and to
