There were 3 histological stains performed on the tumor. Stains were MUC1 (positive), CK20 (positive), CDX2 (weak). Morphologically, the ampullar tumor appears to be pancreatobiliary type. Adenocarcinoma invading from the Ampulla of Vater directly into the pancreas.
The above text extracted from the pathology report. I read the linked report below last year. The principal focus of that report was comparing MIPD (laparoscopic, robotic) to OPD (open PD). Mine was OPD. The paper demonstrates the difficulty of performing a meta-analysis on a broad set of papers and just how much has to be "tossed" because it isn't trustworthy for various reasons.
I spent considerable time with ChatGPT and grok3 entering all of the fine details of my experience last year. My weight loss (161 -> 136), multiple post-operative infections and histology data pushed me to the 23% end of the 23% to 67% 5 year survival. The multiple CT scans also uncovered a abdominal aortic aneurysm that is inoperable and likely to take me out before a recurrence of the cancer. It has been an "interesting" year.
Is your aneurysm inoperable because of calcium deposits?
