Pathologic response according to the tumor regression grade (TRG) scoring standard. A TRG1, absence of residual cancer cells and an abundance of fibrosis.

D TRG4, presence of abundant residual cancer cells that predominate over fibrosis; and E TRG5, almost completely cancer cells with an absence of fibrosis
