Abstract

As an important determinant of the response to chemotherapy, measurements of cellular drug resistance may provide prognostically significant information, which could be useful for optimal risk-group stratification. The objective of this report is to determine the relation between in vitro resistance to 12 drugs, measured with the colorimetric methyl-thiazol-tetrazolium (MTT) assay, and long-term clinical response to chemotherapy in 152 children with newly diagnosed acute lymphoblastic leukemia. At risk-group stratified analyses, in vitro resistance to prednisolone, L-asparaginase, and vincristine were each significantly (P < .01) related to the probability of disease-free survival (pDFS) after combination chemotherapy. The combination of data for prednisolone, L-asparaginase, and vincristine provided a drug-resistance profile with prognostic independent significance superior to that of any single drug or any other factor. The 3-years pDFS was 100% for the group with the most sensitive profile, 20% of all patients, 84% (SE 6%) for the group with an intermediately sensitive profile, 40% of all patients, and 43% (SE 8%) for the remaining group with the most resistant profile (P < .001). In conclusion, the extent of in vitro cellular resistance to prednisolone, L-asparaginase, and vincristine, measured using the MTT assay, was significantly related to the clinical response to combination chemotherapy. Treatment failure in newly diagnosed childhood ALL can be predicted based on cellular drug resistance data.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
