Tumour immunoreactivity (TI) for nm23-H1 (compared with normal bronchial epithelium (NBE)) in relation to the histological features and stage of the resected tumour
| n | TI<NBE | TI=NBE | TI>NBE | |
|---|---|---|---|---|
| In 32 of the 42 cases assessed by immunohistochemistry, normal bronchial epithelium could be identified on the same section. The intensity of immunoreactivity in the tumours in these 32 cases was compared with the respective normal bronchial epithelium. | ||||
