What does borderline resectable mean to you? | ||
The primary tumor can only be resected by surgeons with particular expertise | 26/99 (26.3%) | 2/15 (13.3%) |
The resection of the primary tumor inherits a high risk for (incomplete) R1 resection | 73/99 (73.7%) | 13/15 (86.7%) |
The tumor can be resected R0, but the oncological outcome after surgery is questionable | 16/99 (16.9%) | 1/15 (6.7%) |
The morbidity of a resection of the primary tumor exceeds the normal morbidity by far | 9/99 (9.1%) | – |
Is not important – either a tumor is resectable or not | 2/99 (2%) | – |
What defines borderline resectability? | ||
Tumor contact to the portal (PV)/superior mesenteric (SMV) veins on imaging – likelihood of a PV/SMV resection | 29/99 (29.3%) | 8/15 (53.3%) |
Tumor contact to the hepatic or mesenteric arteries on imaging | 35/99 (35.4%) | 4/15 (26.7%) |
Tumor contact to the PV/SMV up to 180° on imaging | 31/99 (31.3%) | 6/15 (40%) |
Tumor contact to celiac, hepatic or mesenteric arteries up to 180° on imaging | 43/99 (43.4%) | 5/15 (33.3%) |
Tumor contact to the PV/SMV of more than 180° on preoperative imaging | 40/99 (40.4%) | 5/15 (33.3%) |
Tumor contact to the celiac/hepatic or superior mesenteric arteries of more than 180° on imaging | 19/99 (19.2%) | – |
Tumor related portal vein thrombosis on imaging | 16/99 (16.2%) | – |
Resectability cannot be assessed on imaging only | 12/99 (12.1%) | 1/15 (6.7%) |
