The errors of thymidine labelling in breast cancer.
The site to site error and reproducibility of counting error have been assessed in the routine thymidine labelling of breast cancer. Despite modifications of technique designed to minimize these errors both were found to be inaccurate to within 0.5 labelling index %. Since the majority of tumours had labelling indices below 2% this measurement is not a critical determinant of tumour behaviour.
