Thanks for all the expressions of support, everyone. It is so wonderful to get such helpful, kind responses.
Fortunately, my husband has improved a bit over the last day or two. His oncologist lowered the dosage for his last chemo infusion this past Thursday, and though he had a rough couple of days immediately after chemo, he actually got up and did a few things today.
I 'll keep my fingers crossed that he continues to get stronger before his next chemo on May 1.
Basically, after some research, I realized that my DH needs to call the shots. I think this is what NWGirl is saying as well. Though he is definitely in fluctuating states of denial, he needs to handle this the way he sees fit. If he feels the chemo is important, then so be it. Obviously, if he gets as sick as he was a week ago, I'll still advocate for at least an extra week respite from chemo, but for now he is content with the treatment. He keeps telling me repeatedly that he is "used" to it, though I can't imagine how anyone can acclimate to it, especially when someone is so weak, but that's how he feels.
I did some research last night about how to deal with denial in terminally ill patients. What I discovered is that about 80% of colon cancer patients operate with varying degrees of denial, while only about 20% are able to face the facts head on. The current belief in health centers today is that denial is a functional coping mechanism and there is some evidence that it appears to extend lives since there is less stress and anxiety. It's an adaptive mechanism that allows people to function. The only time when denial is not good is when it causes the patient to ignore medical advice and not get treatment. However, most mentally sound individuals accept and continue treatment even if they are experiencing high levels of denial.
In 2012, research at Dana Farber revealed that CRC patients experience the highest levels of denial as compared to the terminally ill with other forms of cancer. Denial in that study was based on a patient's false belief that chemo can cure when it is given to those with metastatic Stage 4. Even though doctors supposedly make it clear that with the disease progression that widespread, the only use for chemo is to keep cancer symptoms in check for as long as possible and to extend life for some months, people in denial continue to believe it is curative. That is exactly where my husband is at. Though I've sat with him when the oncologist has flat out told him that exact thing, he continues to believe chemo may cure him. The Dana-Farber article also mentioned that Stage 4 patients have been known to deny being ill after chemo infusions since they are afraid the treatments will stop and sometimes get very ill because they won't share this necessary info with the doctors. They have also been known to carry weights in their clothing when they are weighed so that the treatments won't stop due to excessive weight loss. (May 1st I'm checking my DH's pockets!
)
I also learned that the prevailing opinion at this time is to not disabuse a terminally ill patient about their unwillingness to face facts; however, caregivers and health professionals should not consciously encourage denial either. For example, if the patient asks something directly about his/her treatment, then one should be honest in response though in a humane way.
I'm sorry I've gone on so long about this, but I think it is interesting. Lord knows that I exist in denial about many things (my weight for one thing!), and I like living in that world, so why should I tinker with my husband's?
Also, the articles I read stated that denial is dynamic in that it can change minute-to-minute or day-to-day. Caregivers need to listen carefully and be there to support their loved ones. The worst thing to do is to withdraw at a time when they are most needed.
I think I was feeling conflicted because in part I felt I might be negligent to allow him to continue treatment when the side effects have been so bad, but the choice is really the patient's and the health care team. I will continue to advocate for his best interests, but I shouldn't get so frustrated that my DH is allowing himself to suffer. He is doing what is best for him.
