Prognostic significance of solid growth in endometrioid endometrial adenocarcinoma.

Although > 75% solid growth was most significantly associated with many of the adverse prognostic factors, this subset did not provide prognostic superiority in predicting adverse survival when compared to subsets within 6-75% solid growth. In conclusion, although no statistically significant difference in survival was found among subdivisions of architectural grades 2 and 3, solid growth, especially ≥ 8%, appeared to be an independent prognostic factor for survival in patients with early-stage endometrioid endometrial cancer.
