Abstract

Quantitative measurements of oxygen tension in tumors and normal tissues of patients were made by the oxygen cathode technique before and after radiotherapy. Statistical analysis showed that log oxygen tension has a normal distribution. The ratio (tissue oxygen tension when breathing oxygen/tissue oxygen tension when breathing air) = K, a constant of mean value 2.1 to 2.3 for muscle, subcutaneous tissue, tissues near tumor, and tumor before treatment. Afier radiotherapy, K is sigrificantly higher for tumor, but for no other tissue. The effect of the radiosensitizer Synkavit on the oxygen tension is described. Warming by diathermy reduced tumor oxygen tension and the response to breathing oxygen. The findings encourage use of oxygen inhaled at atmospheric pressure as a radiosensitizer, but patients require 7 to 8 l/min for 30 min, to obtain maximum tumor oxygen tension. (auth)

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.
