Abstract

Based on our experience with conventional, daily irradiation, a split-course radiation schedule was introduced in 1978. The schedule, which was based on Cohen's models for squamous cell carcinoma and vascular damage respectively, predicted an improved tumour control and a reduced rate of late complications, e.g. late oedema, if the conventional, daily treatment was replaced by a split-course schedule. The schedule has later been abandoned, but the experience gained from split-course treatment at various dose levels has been analysed and the results compared with those obtained by conventional radiation. The data allowed construction of dose-response curves and estimation of iso-effect doses. Split-course treatment was associated with a significantly reduced therapeutic ratio because, disappointingly, it did not improve tumour control, and the severity of late complications grew. No late complications were avoided by introducing a 3-week pause in the radiation therapy regimen, nor was the tumour response improved despite a 12-Gy increase in total dose. This indicates a significant repopulation corresponding to more than 0.5 Gy/day, equivalent to an up to 100-fold increase of the number of clonogenic tumour cells during the pause--an increase that occurred despite the decrease, clinically, of the tumours during this period.

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.
