Thanks for your critique re using Wikipedia as an information source. Though I too find Wikipedia posts occasionally somewhat inaccurate and/or incomplete, IMHO they are often helpful when read with a critical eye. Coincidentally, lately I began reading "The Last Lecture" by Randy Pausch, his personal story as an academic and pancreatic cancer patient who died just a few months following his diagnosis. This relatively young, tenured professor at Carnegie-Mellon was an advocate of using Wikipedia.
On another note, thank-you. Your comment caused me to go back and poke around a bit. While poking around I came across this informative article regarding ctDNA testing as a prognostic biomarker for managing resectable pancreatic cancer.

I begin the next phase of my neoadjuvant treatments tomorrow (3 weeks of radiotherapy with reduced dose chemotherapy) before my anticipated modified Whipple in January. Thanks again.
