It does not matter how healthy you look. It does not matter if your hair is growing back or you walk a little faster or manage with just one nap a day now.
It does not matter if any of those things are true, your cancer can be worsening.
As I have described here before, metastatic breast cancer is characterized by resistance to therapies. If a treatment works in the first place (and according to my oncologist, most have about a 30% chance of initial success), the cancer will almost certainly become resistant to it and it will cease working. This resistance will happen time after time. This has happened numerous times to me already. I have had some treatments not work at all (Taxol, Fulvestrant+clinical trial drug GDC-0032) while others worked for a few months and then would not work any longer (Xeloda, Aromasin+Afinitor) .
Once again, this resistance has happened. Carboplatin and Gemzar did their work starting in March and did it well, bringing me back from a very dark place this Spring. After 9 complete cycles, though, they are no longer working. It is time to move on.
Moving on is scary. It means being in freefall as we use educated guesswork to decide what agent(s) to try next.
The good news is that I was officially approved to receive palbociclib from Pfizer under their expanded access (compassionate use) program. I will be able to get this drug before it receives final approval by the FDA and therefore before it is on the market sometime in the next year. There is no guarantee this drug will work (alone or in combination with other drugs that are on the market already). It is just one more thing to try.
There are still final bureaucratic hoops to jump through, though, and I won’t have it for at least a few more weeks. This presents a problem: I need a new therapy now. I cannot safely be without treatment for that period of time. It also is best for me to be in a state of control when I start it; the higher a cancer load I carry the harder it would be if what the drug does is provide stability rather than cancer regression. Stability is considered success in metastatic breast cancer drugs. Just keeping things the same, preventing cancer progression, is good. This is considered “success” in using a drug for metastatic breast cancer. However, if you start at a very high cancer load, that stability may be quite intolerable. My oncologist and I feel it is best to have that load brought down (not just held steady), and we don’t know if this drug is a workhorse like that. We can’t count on it to be.
I’ve known for the last week that things were probably over for this chemo. We had tried a higher dose of both drugs already without success. I adjusted to the news over the weekend and yesterday I started on a new chemotherapy regimen. Navelbine is given through my port as an IV “push”; it’s just one syringeful that is given in about 30 seconds. Having a port is really helpful for this one because it is very irritating to veins if you do not have a medi-port implanted in your chest like I do (the port is completely under my skin, it is a lump about the size of a nickel and is accessed with a special needle by the nurses. They can take blood from it, give medication and chemo through it the way you would with an IV except you don’t have to use an arm vein). We are initially planning on a schedule of two weeks on, one week off, but that may change as we go. And of course, if it isn’t working, we’ll have to try something else.
I’m having some other problems now that the cancer is growing so that has been a challenge. Side effects don’t just stop the minute you stop taking a drug. And moving right on to another one means there is no break. It is what is needed though. The good thing is that if you find something that works (like the Carboplatin and Gemzar did for me), they can do astounding things to kill the growing cancer and bring it back under control.
Metastatic breast cancer is like Whack-a-Mole: cancer pops up in places and then can often be whacked back down. If you’re lucky you can play this game for a little while as it takes up residence in different bones and organs. We’ll see how successful we are this time. This is always the hardest time for me mentally: living with the uncertainty of trying to find a new regimen, trying to find something that works, knowing right now there is nothing.
But this is the choice I have made in choosing to treat my cancer. That is the nature of this disease. These are not heroic measures. This is what treating metastatic breast cancer is.
And so we go… onward.
I have become an expert in uncertainty.
I don’t know how I will feel from one day to the next. I don’t know if the chemotherapy that worked a few weeks ago will still work today. I don’t know how my body will tolerate what I’m doing. I don’t know how long this all will last.
I was supposed to get chemo a few days ago (Tuesday) as usual. However, when I arrived and had my bloodwork done I found out that the higher dose of Carboplatin the week before had really continued to hit my body hard. My platelets were too low to safely receive chemo. This means I had very little clotting ability. The Gemzar I was due to get that day hits platelets hard so it presented an even more dangerous situation. My hemoglobin was on its way down, too. I was told I couldn’t get chemo as planned.
Instead, during what turned out to be a 13 hour medical day, I received two bags of platelets by transfusion and one unit of packed red cells. I had never received platelets before. I had no idea what they looked like… they look like pale orange juice (shown at left).
This is a great opportunity to share a link to Sloan-Kettering’s online information about blood and platelet donation and eligibility criteria. I do not need designated donations at this time but I do rely on donor blood and platelets so if you are eligible please donate when you can! It’s a great way to help those with cancer for free.
Today (Friday) I was finally able to get chemo. We will see how I tolerate this dose but the plan now is that rather than receiving my next Carbo/Gem in 14 days, I will get it in 11 days to get back on schedule. This means I will have to do a few daily Neupogen shots next week to boost my white count.
There will be another book auction this year with proceeds going to my fund for metastatic breast cancer research. Authors you know and will recognize are donating signed copies in many genres. I will be sharing links here and on my blog Facebook page if you want to window shop or place a bid. That will be in October. Thanks to Erika Robuck again for arranging this; I know it’s a lot of work.
Wishing you all a good weekend, we expect a last burst of summer here in Connecticut.
I am writing this on Monday night; by the time email subscribers read this it will be Tuesday and I’ll be done with chemotherapy again, having risen before dawn to head down to New York’s Memorial Sloan-Kettering
First let me report the good things. I have had some great days after my transfusion last week for severe anemia (expected often now after this much chemo).
On Friday night I drove Colin in heavy traffic to his first travel baseball game (took two hours). Then I sat watching warmup and the game which was another 3.5 hours. Then an hour home. I am detailing that time to brag. Look what I did with my son.
It wasn’t physically easy for me. But it was joyous. We got so punchy in the traffic jam that we were waving our hands in the air “seat dancing” to the music. We nicknamed a car “Duck Dynasty” that was broken down by the side of the road and then got lost at the venue and ended up 4-wheeling over gravel hills. We had a blast. Here is my precious middle child when we arrived at the field. The team won which was exciting. It was his first game on a full-sized field and also under the lights. I also got to take him 
to another game on Sunday; the team lost that one but it didn’t much matter to me. I got to not only be there to cheer the boys on, but also bring them water and popsicles on a scorcher of a day on the field.
The medical update since the last post is that in short, there isn’t a good clinical trial that I qualify for/am willing to enroll in right now. The chemo regimen that I am on makes me ineligible for some because it affects my blood counts so severely each time now (quite a catch-22, I would need to go off chemo to even have a chance at being considered). One trial I can’t be considered for because there isn’t enough tissue left from a previous biopsy to use it for required testing. Because my cancer is primarily in bones or other places inaccessible by surgery, this is not an easy problem to fix.
Now I’m going to get a bit technical. I’m hoping to explain a bit about how the different clinical trial types work since many people don’t know these distinctions. Consider this your breast cancer education for the week! Yeah, you know I’m not a doctor so I’m explaining this to the best of my ability. Ask a doctor for more info, especially one who works in clinical trials to be sure the trials you or a loved one might be considering work the same way.
Here we go:
One type of Phase I clinical trial (which I would qualify for) is risky enough that this option isn’t reasonable to me right now. Let me clearly state that they may become very reasonable options at some point soon and I totally understand why other people choose to do them! These particular phase 1 trials I’m opting out of for the time being are the kind that are testing safety of a medication previously untested in humans. That is, they don’t yet even have a dose that they know is safe. They are called “dose escalation Phase I trials” which means they start with a low dose they think is safe and gradually increase the dose until the side effects become too bad and the test subjects can’t continue and they stop participating. They do these on a small number of people.
This process establishes the maximum tolerable dose and the company hopes to then proceed to a Phase II trial. That Phase II trial tests if that established maximum tolerable dose even does anything measurable (Phase II trials test for efficacy: is this drug keeping the cancer stable or even causing it to shrink?).
To complete the clinical trial trio, a Phase III trial tests the “current standard of care” plus the trial drug against the current standard of care alone. That is, does adding this drug to a treatment that is a normal one for this cancer improve outcomes above and beyond just giving the treatment the patient would normally get (are results better? The same? Worse?). For ethical reasons there are no placebos used alone instead of treatment in Phase III trials in metastatic breast cancer. They would be used only to combine with the standard of care treatment. No patient goes untreated. All get the usual treatment as the guarantee.
This process means that during the Phase I dose escalation trial I first mentioned 1) you don’t know if the trial drug is safe, 2) you don’t know if that dose is too low for some or all of that time to even be doing anything, even if it is eventually going to be efficacious, and/or 3) if it even works at any dose (without making things worse). This means continuing with your cancer potentially untreated for months, an often dangerous proposition in metastatic cancer.
I don’t want to go into more details of those trials but I do think it’s important for me to continue to explain the way that some clinical trials work with metastatic breast cancer.
As I think I mentioned in my last post, the likely immediate plan was to increase the dose of one or both of my current chemo drugs. Because I opted not to pursue enrolling in a clinical trial I will remain on IV chemo. If I had chosen the trial I would need an additional two weeks without any chemotherapy to complete the mandatory washout period where I do not use any medications to treat the cancer because their presence in my body could affect the trial drug results or side effects.
I am going in for an increased dose of Carboplatin and steady dose of Gemzar on Tuesday. I did have one increase already in the Spring on my Gemzar dose. We will see what kind of response we can get from this Carboplatin increase, if any. It will hopefully buy us some time until some other trials open up and/or we can consider if we can do a biopsy once we see a current CT scan.
A few readers were concerned that I was relying too heavily on tumor markers in my decision-making. In short, I’m not. I am well aware (as I’ve said in almost every post except last time) that markers, particularly CA 15-3, are not reliable for many people. This is why this test is not used as a screening test for people to find out if they have breast cancer. If it were valid they would use it instead of or in conjunction with routine mammograms.
I know many doctors don’t use blood tests for markers at all and for some types of breast cancer they are totally worthless. Trust me, oncologists at Sloan-Kettering are well aware of all of this information as am I. The most important piece of information is a history of them in me and how they correlate with scans and my disease progression. I am one of the people for whom they are tightly and reliably correlated with my disease. We have had seven years of studying them in my particular case and two years with close monitoring during metastatic disease. So while I definitely appreciate the concern, you can rest assured that we make decisions with all of this in mind. It was my error in not putting that usual caveat in that last post.
So… for now the plan is: higher dose of one of two chemo agents on Tuesday. Test markers to see what they’ve done in last few weeks.
In case you are curious, going for chemo doesn’t just mean getting two drugs. The infusions I will get on Tuesday are numerous. I will get the following 8 infusions in this order: Decadron (helps with nausea and mainly to help prevent an anaphylactic reaction to Carboplatin because I’ve had more than 6 infusions), Pepcid (helps with anaphylaxis prevention and also bonus heartburn help), Benadryl (helps prevent anaphylaxis), Carboplatin (chemo agent #1), 1 liter fluids (helps prevent dehydration and bonus helps to keep kidneys functioning well to avoid high creatinine levels that can be dangerous), Aloxi (anti-nausea, blocks signals from stomach), Gemcitabine (chemo agent #2), Emend (blocks nausea and vomiting signals from the brain).
Away I go… thanks for the support. These days of uncertainty are difficult for me. I like a plan.We have a short term one and I am, as always, moving forward. As I wrote in a prior post and re-read tonight:
Cellular biology is King.
But paired to that fateful ruler
I shall be an argumentative, rebellious Queen.
Wring the most out of each day.
Find those bits of joy and beauty,
Make sure that what I’m doing isn’t waiting around to die.
For truly, that would be a waste.
