Fig. 1: Representative images of colon carcinomas from the COLOPEC trial in relation to the free peritoneal surface (H&E stains).

From: The measured distance between tumor cells and the peritoneal surface predicts the risk of peritoneal metastases and offers an objective means to differentiate between pT3 and pT4a colon cancer

A, B (×20) are from cases with full peritoneal penetration where the tumor cells were growing onto the peritoneal surface within peritoneal clefts (in case B with inked surface). C (x20) demonstrates a case where the tumor cells reached directly to the free peritoneal surface (distance of 0 µm, arrow). D (×20), E (×20), and F (×4) show cases where the shortest distance of tumor cells to the free peritoneal surface was 60 µm, 167 µm, and 703 µm, respectively (black lines show the location of the measurements).
