Is there really a "problem with miracle cancer cures"?


In an article in today’s (April 22) New York Times Sunday Review section, a physician named Robert M. Wachter writes about what he calls “The Problem with Miracle Cancer Cures” This problem is that the cures are just good enough to tantalize people without being good enough to make a real difference to most patients. Specifically, he says, “[a] recent analysis estimated that about 15 percent of patients with advanced cancer might benefit from immunotherapy – and it’s all but impossible to determine which patients will be the lucky ones.” So patients lured by the likely illusory promise of the new treatments will continue seeking a cure for their disease when they should be focusing on palliative care, with which they can live their remaining time with more comfort and might even wind up living longer.

Dr. Wachter’s concrete recommendations for what to do about this are fine – he wants to encourage patients to combine palliative and curative approaches; to train doctors to better discuss the pluses and minuses of the choices patients now face; and to press research that will identify those patients for whom the new treatments really might be curative.

But his attitude nevertheless grates. He writes that “by blurring the line between cure and comfort – and between hope and hopelessness – they [the new treatments] have disrupted the fragile equilibrium that we doctors have long taken for granted.” And he cites the case of a woman in her 80s, “clearly dying of lung cancer,” whose family asked about immunotherapy. He writes: “When I reluctantly asked our oncologist about this, he didn’t scoff. ‘It could work,’ he said quietly, as if not quite believing what he was saying.”

What’s most striking about this story is Dr. Wachter’s reluctance even to ask. Why is he so reluctant? Put objectively, the reason seems to be that his patient might then try immunotherapy – which “could work” – instead of focusing, as apparently he feels she should, on palliative care since she’s “clearly dying.” There’s an obvious response to this: it’s the patient’s life. And it’s not clear that patients, clearly presented with the relevant facts, are actually unable to make sensible decisions about their lives, and deaths. Nor is it clear that the best decision, measured on some objective basis and then imposed on the patient without her full and knowing consent, is actually “the best”: there are a lot of arguments against paternalism, though my impression is that some doctors don’t seem to be convinced by them.

To be fair, Dr. Wachter says, and I don’t doubt it, that “[w]e already know that despite the unquestioned value of hospice, many patients with end-stage cancer don’t take advantage of it, or do so with only a few days left in their life, having needlessly suffered for weeks or months.” This may be a sign of patient irrationality, though it may also be a sign of poor doctor-patient communication. It might be the result of insurance problems, as Teresa’s pointed out. Or it may reflect that many doctors, unlike Dr. Wachter, are themselves committed to what he calls a “pugilistic approach to cancer.” (I’m sympathetic to those doctors; I’d rather be cared for by one of them than by the opposite, whom we might call a cancer appeaser.)

In any case Dr. Wachter’s approach doesn’t seem to be motivated by just the objective concern about the making of wise treatment decisions. There is emotion here too, in his “reluctance” even to ask the oncologist about immunotherapy. He also tells us that before the advent of immunotherapy, when patients would sometimes ask him about the option of palliative care, while “the conversation is often heartbreaking, it has rarely been a hard call.” And then he adds: “But now it is.”

Dr. Wachter is clearly a caring person, and I don’t mean to suggest otherwise. (According to Wikipedia, he’s a leader in improving hospital care and with a colleague coined the term “hospitalist” to describe his focus.) But it seems fair to say that he himself is distressed by the emergence of these new treatments; they disrupt not only patient choices but doctors’ equilibrium. Before, he knew what to say; now, it seems, he still feels pretty strongly about what to say – that for most patients the new treatments are not going to help – but what he wants to say is no longer as persuasive to the patients. Moreover, what he would have readily said in the past is no longer as persuasive even to him. In 15 % of cases (to use the number from the study he cites), his advice to turn from treatment to palliation would be quite wrong. The arrival of treatments that give a modest degree of hope makes matters unclear and advice uncertain, and the result is hard for doctors as well as patients.

I have been fortunate (sort of!) in my illness; for almost two and a half years I’ve been treated with chemotherapy, with relatively mild side effects. I don’t face the hard choices about palliative care, with or without further treatment designed to fight my cancer, that Dr. Wachter is describing. And I do understand (even if only somewhat abstractly) that cancer doctors, who care for patients whose prospects are often grim, have a job that can be emotionally wrenching on a regular basis. That said, I can’t say that I share Dr. Wachter’s seeming dismay at the emergence of new, but limited, hope. Let hope spring eternal! I’ll do my best to make careful choices based on the data; as my wife Teresa says, this is something that cholangiocarcinoma patients are experienced in doing. But give me a doctor who rejoices in new hope rather than being dismayed by it, any day.
