Haemoglobin levels in tumour and muscle tissues for deep (A) and superficial (B) tumours. In the superficial tumour group (Diagram B), there was a significantly higher haemoglobin content in tumour tissue compared with muscle tissue before TM-ILP (P=0.009) and 30 min after TM-ILP (P=0.018); the values for the two tissue types were similar by 6 weeks after TM-ILP. In terms of time-dependent alterations in the superficial tumour group, a significant decrease was observed in the tumour haemoglobin content from before to 6 weeks after TM-ILP (P=0.036).
