[Correlation between immunological stage and response to chemotherapy. Results in 64 patients with nonresectable epidermoid bronchial cancers].

Out of 64 patients with non resectable epidermal bronchus carcinoma, 26 patients had before any treatment positive responses of skin tests to recall antigens. In these patients we found a correlation between the reactivity of the skin tests, the presence of seric factor inhibiting the leucocyte migration, the mean count of peripheral lymphocytes and the response to combination chemotherapy protocol. The patients who respond to treatment have a significantly better prognosis than the patients who do not respond. With this correlation it seems to be possible to distinguish between two populations of patients with non resectable bronchus carcinoma : one population with a good risk who can be significantly improved by the treatment : the other population with a very severe prognosis.

Treatment of malignant gliomas and brain metastases in adults with a combination of adriamycin, VM 26, and CCNU. Results of a phase II trail.

Forty-three patients with inoperable or recurring malignant gliomas, and 30 patients with multiple recurring brain metastases were treated with a combination of Adriamycin (45 mg/m2) and 4-dimethyl-epipodophyllotoxin D-thenylidene (VM 26) (60 mg/m2 for 2 days) with 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) (60 mg/m2 for 2 days). These cycles of treatment were repeated as soon as the hematologic restoration was complete. The treatment was well tolerated and the clinical condition of 31 of 43 glioblastoma patients improved during the 2 months after the beginning of the treatment. Six of eight patients with breast cancer metastases, one of 13 with bronchial cancer matastases, and three of nine with other types of cancer metastases also benefitted from the treatment. Examination of the results obtained revealed the following characteristics: 1) This combination had a low degree of efficiency in the treatment of metastases to brain, except for breast cancer metastases; 2) there was no complete correlation between the clinical results observed and the cinegammagraphic developments; 3) the results obtained were similar, independent of the initial localization; and a 6-month median survival period was established, with 10 patients now in a state of apparently complete remission, 180 to 506 days after beginning of the treatment.

Synthesis and pharmacological properties of 4-piperazino-5-methylthiopyrimidines. Selection of new antiemetic agents.

We have synthetized a series of 22 new 4-piperazinopyrimidines bearing a methylthio substituent in the 5 position of the pyrimidine ring. These compounds have been obtained by separation of the isomers formed during nucleophilic attack of the corresponding 2,4,6-trichloropyrimidine by amines. Pharmacological screening has shown that this chemical series displays a very interesting profile, which includes antiemetic, tranquilizing, analgesic, antiserotonin, and musculotropic-spasmolytic properties. We have particularly selected for clinical investigations two compounds with powerful antiemetic activity: 2-methylamino-4-(N-methylpiperazino)-5-methylthio-6-chloropyrimidine and 2-isopropylamino-4-(H-methylpiperazino)-5-methylthio-6-chloropyrimidine.
