I have shared my mum’s situation before but there are some inputs today. We have met the oncologist as she finished her first round of folfiri on 20 Aug. We were supposed to hear some good news such as lowered CEA, but the marker turned out higher then the one before chemo. Now it is 22, which broke the record so far. The onco recommended my mum to go for folfiri one more time then see how does the CEA respond. Onco also compared the x-ray of lungs for mum and discovered the situation seems bit better after the chemo, which made us even more worried about how did the marker climb so high.

Last time we have used Folfox with Avastin while we decided not to use Avastin this time coz it is self-financed. We are now considering shall we add Avastin back. What worried us the most, however, is that folfiri seems not helpful. This is the first t8me of her to use folfiri and she did experience some tough time after chemo (without diarrhea though). If folfiri is not working, then we don’t have anyway way out but keytruda, which is extremely expensive in Hong Kong. Seems that no more chemo way out...

Thanks for read8ng, any advice appreciated.

Do you know if your Mom is MSI or MSS? Have you had any testing done on her mutations? I ask because I was in a dire situation (look at my history. Because I am MSS my oncologist didn't suggest Keytruda since it doesn't normally work for MSS. HOWEVER, when Folfuri stopped working for me, we had my tumor tested via Foundation One and it turned out that my tumor had 11 mutations. Because my tumor had a moderate mutation burden Keytruda worked for me. My CEA has gone from 60 to 1.8 this week. The side affects are minimal compared to chemo....if there is a way to afford it or to get financial assistance if she is MSI or MSS with at least a moderate mutation burden, trying Keytruda may help her.

Vectabix (aka p-mab) has been working well for DH since May of this year. Doctor added partial dose of Irinotican in June and it's helping too but producing a "gruel-like" diarrhea in his ostomy bag we are trying to manage with Imodium. I didn't see the Vectabix in your signature so thought I'd mention it.

You might not have any oncological society accepted or regulator approved way out but keytruda, skipping over stivarga or Lonsurf, options with typically lots of side effects and low success rates.

There have been multiple, important technological avenues earlier that they didn't discuss, and probably have no informed inkling of an idea about them either:
1..Rolle's laser lung surgery, somewhere overseas, mostly Germany.
2..Carbon ion beams, Japan, are probably the highest therapeutic ratio radiation described, but are still more limited on tumor burden quantity than 1.
3..Lin's ADAPT therapy, Xeloda + celecoxib. It really needs more adjuncts for more cancer inhibition effects and easiest tolerance but might have been a good choice even after several rounds of Folfox.
4..Metronomic, immunochemo. Can include or modify #3 and can be modified for Kras mutation(s). Probably can include some Avastin but we haven't needed Avastin for cell kill. Even limited forms of metronomic, immunochemo with comfortable amounts of oral 5FU drug have succeeded in some percentage of late term cases after Folfox and Folfiri failed. The more advanced forms of immunochemo would target a cancer with particular mild drugs and high powered supplements. For Kras mutants, IV vitamin C infusions have been helpful.

We chose #4 for its broad coverage potential, low(est) side effects, easy home use, and low cost. The lung thingies disappeared early on, so we have no experience on higher tumor burden in the lungs.
