N2 - Endometrial carcinoma consists of endometrioid (type I) and serous papillary (SP; type II) subtypes; a rarer form is malignant mixed müllerian tumours (MMMT; type II/mixed). We set out to determine whether one might be able to biochemically signature these subtypes using Fourier-transform infrared (FTIR) microspectroscopy and distinguish non-tamoxifen associated from tamoxifen-associated cases. Paraffin-embedded blocks were obtained from non-tamoxifen associated cases reported as endometrioid (n = 7), SP (n = 4) or MMMT (n = 4). From tamoxifen-associated cases, endometrioid (n = 1), SP (n = 3) and MMMT (n = 4) blocks were retrieved; benign tissues (n = 3) were also analysed. Exploiting synchrotron-based radiation, sections (10-μm thick) on BaF2 windows were interrogated through a 10 μm × 10 μm aperture. Point spectra were derived from 10 locations in each of six glandular elements per tissue; a further 20 stromal spectra were obtained.
