- Figure 1.
EGRF expression in the superficial biopsies and the core biopsies compared with that in the cross-sections. The different biopsies were taken of 24 tumour preparations of head and neck cancer. There was a significant difference in the EGFR expression between the superficial biopsy and the cross-section through the tumour (p=0.013). The same was shown in the comparison between the EGFR expression of the core biopsy and that of the cross-section through the tumour (p=0.036).

The expression of Ki-67 in the superficial biopsies and the core biopsies compared with that in the cross-sections. The different biopsies were taken of 24 tumour preparations of head and neck cancer. There was no significant difference in the Ki-67 expression between the superficial biopsy and the cross-section through the tumour (p=0.153). There was a significant difference between the core biopsy and the cross-section in the Ki-67 expression.

Ki-67-positive tumour cells in the 24 superficial biopsies, 24 core biopsies and 24 tumour cross-sections.

Illustration of how the biopsies were taken. The core biopsy was taken using a 16-gauge needle with a length of 20 mm and a diameter of 1.6 mm. The superficial biopsies had a size of 3 mm.
