Spoiler alert: my rash has returned.
Before I get into the details of this new leg of my journey, I’m taking a moment to reflect on the side-effects of the past. In August of last year (2017), I stopped taking chemotherapy due to signs of progression. After about a month of cleaning out my system, I noticed a serious boost in both my mental and physical energy levels. My body began shaping up. I felt really good. And I started my first “targeted” therapy, the drug Gilotrif (generic name, afatinib).
Gilotrif was highly promising at the time. It had shown some level of effectiveness on the HER2 mutation in cancer studies but was still off-label for my use because it was designed to target a very closely related mutation. I loved it at first, however, because I kept feeling better and — in comparison to my 2 years and 8 months on Alimta (generic name, pemetrexed) — there was just an amazing lack of initial side-effects. Alimta had been fairly easy to tolerate overall and I had no real complaints considering how well it had worked. But I did have some skin and digestive issues, as well as persistent fatigue, that plagued me every month. Toward the end, the skin issues were particularly bothersome, and I was beyond thrilled when they cleared up. Continue reading The Rash Is Back
It has been over two weeks since I began taking my new drug, afatinib. Over two weeks of feeling good, feeling like the chemo has been thoroughly flushed from my system even as I have diligently taken these new pills, feeling the best that I have in three years. I have been keeping a journal this time, chronicling how my body is responding each day, trying to pave the way for a better understanding of how to live with this new treatment. For the first week, anyway, it almost seemed like it was going to be too easy.
There are two weeks of video updates on my Patreon feed, talking about how great I feel and wondering how bad the side effects will be once they really kick in. I had been prepped by my oncologist that it was very likely that I would experience worse side effects than I had with the chemo I had been taking. This was based on how well I tolerated pemetrexed, the chemotherapy drug that had kept my cancer at bay for so long, but not so much on patients in general having a particularly tough time on afatinib. Which is not to suggest that I expected a walk in the proverbial park with this new drug.
Still, the first week was amazing. It was almost like I was taking nothing at all. Sure, there was some digestive stuff going on, but nothing outside of the realm of what I would have been used to in a previous life if I decided to live off of bean burritos for a few weeks. And I love a good burrito, so it would be worth it. But by day eight, I realized that the side-effects of the drug were presenting themselves quite visibly.

I knew that I would not stay on chemotherapy forever. So getting to the point where I ended my “chemo journey” was not completely surprising. In fact, I had anticipated that a change would be good for some time — after over 2 1/2 years of the same routine, not only had it begun to gnaw at me each time I faced another infusion and ensuing side effects, but there was something of a “gut feeling” that the chemotherapy drug I had been on for so long had done about all it could do. I was probably influenced a lot by the promise of Immunotherapy drugs that had become the media darlings of the cancer world. When my oncologist said it was a good time to consider another approach, I was eager to do it.
Besides immunotherapy, for which I had hoped to join a clinical trial, there was the possibility that I might harbor an actionable gene mutation for my adenocarcinoma. My initial genetic analysis from a biopsy prior to starting chemo had shown none of the mutations that were being directly treated at that time. But a couple of years makes a big difference in the cancer world, especially with the increasing rate of progress science has been making over the past few decades. A re-analysis of that old biopsy showed nothing new, but a quick, painless liquid biopsy — two simple tubes of blood and fifteen minutes of my time — revealed that I harbor a fairly rare mutation, one that affects roughly two percent of the adenocarcinoma subset of lung cancer patients: ErbB2, also known as HER2.
This shifted gears for me regarding the drive down my treatment path. It also made me shift perspective. There is the question, now, of whether finding myself in such a cancer minority is a sign of good fortune. On one hand, it means that my genetic demographic is not highly studied — the downside to minority group patients is simply that there are fewer of us to put into clinical trials. Flip that over, however, and it makes the trials that have been done highly specific — and it makes the case studies on patients with this mutation also highly specific. Which in turn suggests that this might be a very positive development after all. Continue reading Frying Pan, Meet Fire – Leaping from One Therapy to Another
