Got this email from my oncologist yesterday, excerpted and edit slightly for clarity:
Your CEA is up slightly to 4.6. I think we should get a CT scan the week of Nov 19th to see what is going on.

This is not good news, and is probably very bad news.

For those who haven't been following until recently, CEA is carcinoembryonic antigen. Per Wikipedia:
It is normally produced during fetal development, but the production of CEA stops before birth. It is not usually present in the blood of healthy adults, although levels are raised in heavy smokers. CEA is a glycosyl phosphatidyl inositol (GPI)-cell surface anchored glycoprotein whose specialized sialofucosylated glycoforms serve as functional colon carcinoma L-selectin and E-selectin ligands, which may be critical to the metastatic dissemination of colon carcinoma cells.

In other words, it's a tumor marker associated with my kind of cancer, especially in its metastatic form.

CEAs can manifest for other reasons. Wiki mentions smoking. Severe bowel inflammation can also cause CEAs to be present.

In my case, while I certainly have bowel inflammation as a result of chemotherapy's persistent ravaging of the cells lining my GI tract, my historical CEA levels over the past four years have not tracked with that problem. They have tracked inconsistently with the presence of tumor activity in my body. In brief, I've had low CEA levels during periods of tumor activity, but I've never had elevated CEA levels except during periods of tumor activity. That is to say, low CEAs are not an affirmative sign that I am cancer-free, but elevated CEAs are always associated with increased cancer activity.

Now, three rounds into my FOLFOX and Vectibix treatment, my CEAs are up to 4.6, about a 31% increase over the 3.5 measured last August when this metastatic presentation was first diagnosed. That would be what we in layman's terms call a trend in the wrong direction.

CEA Levels as of 2012_11_08

The cut off for clinically significant CEAs is 3.1, anything below that is considered normal. For reference, my all time high CEA was 10.9, 5/21/2011 during the early phases of dealing with my liver metastasis. My low CEAs are 0.2 to 0.3 when there's no tumor activity.

So, this likely doesn't mean my cancer has gone into runaway train mode. What is does (probably) mean is that something is growing when it really, really shouldn't be. My somewhat informed speculation as a long term cancer patient (over four and a half years with Stage IV colon cancer plus metastases) is that either the current multi-focal metastatic liver tumors (Bush, Cheney and Rumsfeld) are proving chemo-resistant and growing despite the current regimen, or that a new metastatic tumor or tumors have appeared elsewhere and are proving chemo-resistant.

Neither of these is a good thing, though I have no real notion which would be worse. "Worse" isn't really a concept that applies in my world anymore. Everything's bad, basically.

My special horror is that Rumsfeld, the tumor at the back of my liver adjacent to the peritoneum, has begun to interpenetrate the peritoneal wall, and that I now have peritoneal cancer as well. This is an issue I brought up with both my OHSU oncology team and my Johns Hopkins oncology team last summer, when I queried whether surgery could best come before chemo specifically to deal with that possibility, just in case this round of tumors proved chemo-resistant and continued to grow. All four oncologists I saw felt that chemo before surgery was a be a more responsible option.

If I was right, if this is peritoneal interpenetration generating the new spike in CEAs, I am going to have to ride myself my hard not to pitch a truly epic shit fit. It won't do any good if I do, after all. And it's not like anything in oncology can be stated with certainty. This is a medical specialty that relies almost entirely on statistical outcomes, and individual disease progression can only be observed in realtime, not forecast with sufficient accuracy.

My best guess now is that we'll stop this chemo, have surgery in early to mid December, and pick up with the newly approved fourth chemo series, which is based around a drug known as Regorafenib. This would put me on chemo through June or July, most likely, and mean the past two months have been a waste of time.

My emotional landscape on this is complex but unsurprising. If we have to abandon Vectibix, that's another year shaved off my already profoundly foreshortened life expectancy. If this is peritoneal disease (only one of a number of possibilities), it will not be the first time I've been right about something very important in which I was then overruled in by medical advice. No matter what it is, my fear and frustration and depression are all multiplied. I won't know much about any of this until the CT scan results are interpreted and released to me, likely not for a week to a week and a half. Uncertainty, of course, is my greatest demon.

Whatever this means, I will adapt and adjust. I always do. But for now, I am very, very upset.

ETA: This post was written while still on the 5-FU pump in the current round of chemo. My apologies for the larger number of typos and misstatements than usual.

Jay, as always, our thoughts are with you.

This would suck for anybody, but you're talented and smart and charming -- not to mention devastatingly handsome.

It's not fair. But you know that better than anyone.

Good luck Jay.
Those elevated counts also reflect the cancer fighting the chemo--I kick out higher counts with each dose too. Could mean the chemo is working.
Be well my friend. We know how hard this really is.
Fricking hard.

I am very sorry to hear this. My thoughts are with you.

Seems today is the day for really crappy cancer announcements. My parents told me this morning that my Mom has cancer. Biopsy and PET scan this week so we can type it and determine next steps.

Fuck Cancer.

FUCK cancer.

And sucks to feel I-told-you-so in such terrible, ludicrous circumstances.

Sorry. I hate it when this happens. It's not wrong for you to feel upset. Uncertainty, of course, is the worst, because you have to contemplate not just one but many possible bad scenarios, and you can't do anything. That's a lot of stress.

Damn it. I hope, on so many levels, that it is not what you fear re: peritoneal matters.

Fuck Cancer.

This so sucks. I'm sorry to hear it, and hope that it's, at the very least, peritoneal cancer on top of everything else.
