[Individualized interval shortening in the chemotherapeutic induction treatment of solid tumors (author's transl)].
Sequential chemotherapy with vinblastin and bleomycin, as well as adriamycin and cis-platin, was administered to 29 patients with disseminated malignant testicular teratoma. In order to intensify the induction phase, the intervals between drug administrations were individually shortened, with the next course of treatment following directly after the phase of critical leucocyte depression. This method was pursued over four courses of chemotherapy without dose reduction, followed by courses of chemotherapy in a conventional three-weekly rhythm. A response was obtained in 28 patients, 18 of them achieving complete remission. Taking into consideration unfavourable prognostic factors in the treatment group, this result is better than after the same chemotherapy at three-weekly intervals. Induction treatment adapted to leucocyte response carries with it the risk of higher toxicity, but this would seem to be acceptable in view of the improved long-term prognosis. This or similar intensification of the first treatment phase, for a long time used with leukaemias, could also be considered in the management of various chemotherapy-sensitive solid tumours, especially in younger patients.
