MP, micropapillary; S, solid; S/MP+, solid or micropapillary subtype present; S/MP−, both solid and micropapillary subtype absent; S/MP5, solid or micropapillary subtype proportion of 5% or less. P‐values by log‐rank test and hazard ratio (HR) and 95% confidence interval (CI) estimated by univariate Cox model.
