Necrosis, sarcomatoid change, overall stage 12 vs 34

TUMOURS, TUMOUR, NECROSIS
These three targets are linked by the finding that models built using the whole/high/low ROI set involve only shape features (Table Overall stage is a measure of tumour size and spread to other organs and lymph nodes. Our results indicate that higher stages are associated with the presence of necrosis: the necrosis status concurs with the overall stage for 71/91 tumours. Furthermore, all tumours with sarcomatoid change had both necrosis and overall stage 3 or 4. Such associations between the target variables may explain why models from the whole/high/low ROI set use only shape features for all three targets.Figure
