Low Platelets

Postby boxhill » Tue Jun 12, 2018 6:59 pm

Despite feeling great, I wasn't able to be infused for Round 4 today. My platelets had sunk from 104 last time to 63. My WBC has gone down to 2.4 (I started out at 2.9), but it's the platelets that have taken a nose dive from a starting point of 179.

I told them I wanted to power on through if at all possible, but the oncologist said no way. If the platelets went down further after this treatment I could be in serious trouble. So my infusion is being put off for a week, and they are considering reducing the oxaliplatin dose going forward.

I'm frustrated, and worried that I won't derive maximum benefit with a lower dose. But it appears that there is basically nothing I can do to bolster the platelet production.

My new norm for platelets is low 50s and I still get chemo. My oxali is around 60 to 70 % strength, and we have to stretch it out to every three weeks. We've been tossing around different things to try to get the platelets up because it's a real concern. Disqualifies me from some trials.
48 @ diagnosis Sept 2014
MSS; Kras mutant G12D
Oct 2014: right hemicolectomy
Dec 2014-May 2015: Folfox
June 2015: clean scans
Sept 2015: scans reveal ovarian mass and liver met; Folfiri
Jan 2016: liver wedge resection and hysterectomy
April 2016: multiple lung mets; Folfiri+Avastin
June 2017: lung mets growing; switch to Folfox+Avastin
Jan-April 2018: dropped oxali; CEA rising
May 2018: back on Folfox+Avastin, add pulse steroid treatment to get platelet count up (continuously in 50s)

And this week it's neutrophils! Down to 0.7, won't treat under 1.0, afraid chemo today would push it below 0.5 and I would be open to potentially serious bacterial infections. I'm willing to risk it, but my oncologist isn't.

My platelets are back up to 175, my hematocrit has just edged up into the normal zone for the first time at 34.6, and Hgb is the highest it's been, at 11.8. The ANC was probably even lower last week, I'm told, which may be why I had a sore throat starting Thursday that went away on Monday.

Now the plan is to go back Tuesday and hope it has recovered enough. I'll receive a prophylactic shot of Neulasta on Thursday when they remove the pump. He plans to reduce the dose of Oxi, and/or possibly the bolus of 5FU. My bone marrow just isn't cooperating.

I am SO frustrated. This means I will have missed a full 2-week cycle. And I feel fine. I get all geared up for the infusion and the pump, go in, and nada. I'm trying to be philosophical, but failing. It is such a roller coaster.
