It's not quite the exciting package one hopes for that appeared on the front porch today. No fun new pair of shoes from Nordstrom or random gadget from Amazon. This package is filled with potential to cause a range of symptoms from nausea, vomitting, diarrhea, fatigue, low white blood cell counts and mouth sores...just to name a few. But, this small box of 21 capsules is also filled with hope, potential stability and the return of healthier days. The only thing I do know for sure is that this package is filled with a whole lot of uncertainty. And although I am used to living with a great deal of it, this time the unknown seems a bit scarier.
This new medication is one of two new drugs I will be starting this week. This oral medication is called Ibrance, and is also known by the generic name of Palbociclib. Ibrance is what is known as a "targeted therapy". In very simplified terms, targeted therapies aim to attack the cancer cells without harming the body's normal, healthy cells. Therefore, targeted therapies, while they come with their own list of side effects, aren't as toxic as traditional chemotherapy agents. Ibrance is a targeted drug that blocks proteins in the cancer cell which in turn helps prevent the cells from dividing to create new cancer cells.
I will be taking Ibance daily for 3 weeks, followed by 1 week off which will allow my body some time to recover and for my blood counts to bounce back up. Due to the high risk of my white and red blood cell counts dropping significantly, I will have blood work drawn every two weeks to make sure I am safe to continue on this treatment.
Not only does this week mark the start of Ibrance, but it will also be my first time receiving Faslodex. The drug has the generic name of Fulvestrant and is the intramuscular injection that I will receive every two weeks. The two of these drugs together have shown very promising results in recent studies. You could read about that here. Faslodex is known as an "estrogen receptor downregulator" which means it binds to the estrogen receptor site of cells and causes the receptors to break down, thereby preventing the normal cellular responsen to estrogen. This is important since my breast cancer is fed by estrogen. Even though I am in medically induced menopause, we want to make sure there isn't any other way these cancer cells can by fed by any stray estrongen that may be floating around.
I will receive my first injection of Faslodex on Thursday, along with my monthly injection of Zoladex that keeps my ovarian function supporessed. On Friday I will meet with a gynecological oncologist at Karmanos to discuss my surgery to have my ovaries removed.
Fingers crossed that I tolerate this treatment well with as minimal side effects as possible. And of course, that this treatment plan is successful! I have blood work next week to check how my counts are responding and will then see Dr. F the week after that to see how I am tolerating the treatment. It sounds like I will have scans in about 3 months to see how things are looking.
As always, thank you so much for the love and prayers. Please keep them coming!
ps - We just got back from a trip to California where I was invited to the Dr. Susan Love Research Foundation Metastatic Breast Cancer Collateral Damage Project. I am really looking forward to sharing more about that soon. But until I have the energy to write that post, enjoy these little snapshots of my free day spent with Mike. :)
