After my pathology report came back, my next step was to make an appointment with an oncologist to find out what my treatment plan would be. I had a specific doctor in mind, so it was about three weeks before I could get an appointment. This was a long wait, but I tried to keep myself calm and spent the time writing down all of the many questions that were floating around in my head. I had also gone back to work by this point, so I was trying to focus on that and getting back to some sense of normalcy, even though life at that point was far from normal.
The doctor walked into the room, sat down, and the first thing he said to me was “stage 3, wow, what a shock, huh?” Finally, someone acknowledged what had been going through my mind since the pathology report came back! He went over the protocol for my stage of cancer. Due to the high risk of recurrence, six months of chemo was recommended. I had a choice between two protocols. One option was the Capox regimen, which would be a combination of an oxaliplatin infusion every three weeks along with oral chemo pills for 14 days, then seven days “off.” The other option was Folfox, which would be an oxaliplatin infusion every two weeks, with each infusion followed by two days with the 5-FU pump. He explained that because the Capox regimen only has the oxaliplatin every three weeks, the dose is higher and there is therefore higher toxicity associated with Capox vs. Folfox. Although the pump sounded like a pain (which it is), I opted for Folfox because I wanted to minimize the toxicity of my treatment. Since I was going to have the pump, a chemo port would be required, so I was scheduled for the port placement procedure the following week.
I was also offered an opportunity to participate in the Circulate – North America clinical trial. This trial is looking at whether circulating tumor DNA (ctDNA) should be used to guide treatment decisions for colorectal cancer patients who have undergone resection of their tumor (obviously I am not a medical professional, I am simply restating my understanding of the study, so take it with a grain of salt). The trial first involves a blood test for ctDNA. For this test, a sample of tumor tissue is analyzed to identify the primary mutations in the tumor. Then a blood sample is analyzed to see if those mutations are currently present, indicating that cancer cells are still being shed into the bloodstream. In the trial, if the ctDNA test is negative, then the patient is randomized into either a monitoring group that does not receive chemo, or a group receiving the traditional chemo treatment (either Folfox or Capox). If the ctDNA test is positive, then the patient is randomized to receive either a traditional chemo regimen or a more aggressive form of chemo (Folfirinox). If at a later point someone in the negative group had a positive ctDNA test, they would then be randomized to one of the treatment groups.
After talking this option over with my doctor, I decided to enroll in the study. I would be receiving the ctDNA test anyway, and I could always withdraw at any time if I decided I no longer wanted to participate. I had strong reservations about not undergoing chemo since I had such a large number of lymph nodes involved, but I decided to enroll in the study and see what happened.
I was allowed to have one cycle of chemo while I waited for my results. My first chemo infusion was on March 9. About two weeks later, I got a call from the clinical trial coordinator telling me that my ctDNA results came back. My test was negative! This was good news. However, I also learned that I had been assigned to the “monitoring” group that would not receive chemo. This left me with a big decision to make. I told the coordinator I would sleep on it and give her an answer the next day. It didn’t take me long to make a decision. My doctor told me that my chance of recurrence would be 25-30 percent even with chemo. I needed to know that I did everything possible to kill my cancer for good, and taking a “wait and see” approach just did not feel right. I called first thing the next morning to tell the coordinator that I was withdrawing from the trial. At that point, my next two chemo infusions were scheduled, and I was relieved to finally feel like we had a solid plan after so many months of uncertainty.
