Abstract

Aims: To analyse the expression patterns of GLUT1, p63 and p53 and the possible correlation between these markers in uterine serous papillary carcinoma (USPC) and endometrial intraepithelial carcinoma (EIC). Methods and results: Fourteen cases of USPC, 12 of which also showed EIC, were examined for GLUT1, p63 and p53 immunoreactivity. Four-micrometre sections from formalin-fixed paraffin-embedded tissue were immunostained using commercially available primary antibodies and Dako Envision Plus reagents for visualization. Membranous GLUT1 immunoreactivity was observed in all cases, including all 14 invasive tumours (100%) and 11 of 12 associated EICs (92%), and was confined to neoplastic cells. In USPC, staining tended to be strongest in superficial antistromal regions. p63 positivity was found in 8/14 (57%) USPCs and 9/12 (75%) associated EICs. In 11 cases p53 was overexpressed in both invasive USPC (11/14; 79%) and EIC (11/12; 92%). p53+ USPCs tended to be positive for p63, whereas p53- USPCs were also negative for p63. Conclusions: GLUT1 is expressed in the vast majority of USPC and EIC, suggesting a biological role during the early steps of carcinogenesis in endometrial serous neoplasms. GLUT1 expression may be induced by hypoxia-related as well as other mechanisms.
