Scintillation counting as an in vitro method for assessing the pretherapeutic effectiveness of planned tumor chemotherapy in patients with ovarian cancer

In vitro testing methods to obtain information about the proliferation of the tumour, which we want to treat by chemotherapy, have been vindicated by the biological individuality of ovarian cancer cells. The determination of the incorporation rate of 3H-thymidine in cells of ovarian cancer by scintillation counting may be recommended as a prognostic factor in regard of success of chemotherapy in patients with this disease.
