Six micron paraffin sections of paraformaldehyde-fixed endometrial currettings of 21 benign and neoplastic endometrial specimens were assayed for tumor cell-specific oncogene expression by in situ hybridization with probes for six oncogenes, beta-actin, and the E. coli plasmid pBR322. In the benign hyperplasias and invasive adenocarcinomas, multiple oncogenes, including erbB, fms, c-myc, and Ki-ras were expressed at significant levels. For the adenocarcinomas, statistical analysis demonstrated that high levels of expression of fms-complementary mRNA correlated strongly with clinicopathologic features (high FIGO histologic grade, high FIGO clinical stage, deep myometrial penetration) predictive of aggressive clinical behavior and poor outcome. The authors discuss the role which M-CSF receptor (the fms gene product) and locally-produced M-CSF may play in the development of the observed aggressively-malignant phenotypes. They also propose that pre-hysterectomy assay of fms gene expression in endometrial currettings in FIGO Stage I patients might be clinically useful to help identify preoperatively those patients with deep myometrial penetration or other locoregional spread.
