Who else has had Gem-Abraxane chemo regimen and for how long?

I am understanding this disease as I journey with my husband who had a distal pancreatectomy and splenectomy. No signs of active cancer activity anywhere other than pancreas; tumour ws stuck to a little wedge of the stomach and that wedge was removed. Jury is out on whether Stage 2B or Stage 4. He was on Folfirinox at first and that caused his CA-19 markers to rise post-surgery. He was switched to Gem-Abraxane and markers came down. It would be encouraging for us to know how many here is on that regime, how long it has been and how well everyone on it is doing. My husband has been on it 10 months and it is "long-term" until it no longer works.
