Fig 1.
The representative microscopic features of colorectal cancer with a residual adenoma component.
The remaining adenoma component is present on the left side of the invasive adenocarcinoma component (A). The adenoma component shows low-grade dysplasia without invasive epithelial islands or desmoplastic stroma (B).

Fig 2.
The Kaplan-Meier survival curves based upon the presence of a residual adenoma component.
Patients with colorectal cancers that contained an adenoma component showed remarkably better progression-free (A) and overall (B) survival than those with no such component.
