Distance of tumor from closest margin [Length] in Specimen by Macroscopy

Tumor from Closest Margin Spec Macro

Definition

In a specimen, the distance from the tumor to the nearest proximal or distal margin (cut end) is recorded. The tumor distance to margins is based on macroscopic assessment and confirmed or amended on microscopy ([LOINC: 81182-8] or [LOINC: 81183-6]), especially when the macroscopic size is difficult to assess (i.e. in early gastric carcinoma and diffuse carcinoma).
