Chemotherapy, Quality of Life, and Corporate Profit

“In reality, only 2 major reasons exist for administering chemotherapy to most patients with metastatic cancer: to help them live longer and/or to help them live better.”

So begins “Chemotherapy Near the End of Life: First—and Third and Fourth (Line)—Do No Harm”[1], an editorial by Charles D. Blanke and Erik K. Fromme in JAMA Oncology commenting on an important new study in the same issue by Prigerson and colleagues, Chemotherapy Use, Performance Status, and Quality of Life at the End of Life”.[2] The study, a fairly large randomized controlled trial, discovered that giving last-ditch chemotherapy for “solid tumors” in patients estimated to have less than 6 months to live did neither. Not only was survival time not increased (although the editorialists note that this study was not designed to look at survival), but quality of life (QOL) was not improved. Indeed, and incredibly important, the group that had the best quality of life before receiving this final round of chemotherapy had the greatest drop in QOL, ending up pretty much as bad as the rest of the group. Blanke and Fromme observe that that this may be because they had “further to fall”. This is likely true, but surely the goal is not to give “treatment” that facilitates that fall.

So why do we do it? Were “we”, doctors especially, ignorant of this? Certainly the strength of the results – especially the fact that those whose pre-treatment QOL was the best were those who were most harmed – was a surprise in that it had never been published before, but that “palliative” chemotherapy at the end of life, intended entirely to improve QOL, often does the opposite – is something that every doctor who cares for patients with cancer, including but not limited to oncologists, has seen. Many of us, including many palliative care specialists, usually recommend against such treatment to patients and their families, often to have our voices drowned out by the encouragement from others (particularly some oncologists).

The truth is that the answer, as with so many things involving people, is complex. People do not usually want to die, and frequently grasp at any straw offered to them. Even when they themselves are not sure that they wish to go on, even when their disease makes them unable to make a decision, their family members often take on the role of demanding more treatment. This rarely if ever comes from a desire to cause more suffering for a loved one, but rather hoping that a miracle will occur. When this is encouraged by the physician who offers some sort of hope it is more likely to happen. The distinction between the outcomes of palliation and longer life is not always clear to patients or their families, and indeed “improvement” and “longer life” may mean different things to the doctor saying it (tumor gets smaller, life expectancy extended by weeks) and those hearing it.

The results of this study showing the decrease in QOL for those who were “best off” prior to treatment should be sobering and decrease the use of end-of-life chemotherapy, but there continue to be critics of the work. Some oncologists, typified by the one quoted by Pam Belluck in the New York Times article on the study (“Benefit of End-Stage Chemotherapy Is Questioned”, July 23, 2015) who “noted that patients were seen between 2002 and 2008, before some newer chemotherapy drugs with fewer side effects or the ability to directly target certain tumors or cancer-causing mutations,” still hold out hope. He may be right, but, of course, all studies are done in the past, and the “things are better now than then” refrain is almost always the one we hear from people unhappy with the results; in all probability, things, for end-of-life cancer patients, are not really better now.

The one clearly unacceptable reason for doing such therapy is the financial benefit to the manufacturers of these chemotherapeutic agents, but also to a lesser degree the providers – mainly the hospitals but also sometimes the doctors – who administer them. This is a major consideration, not generally addressed in the articles about this study. “Costs aside,” Blanke and Fromme write, “we feel the last 6 months of life are not best spent in an oncology treatment unit or at home suffering the toxic effects of largely ineffectual therapies for the majority of patients.” The costs that they are holding aside are the costs of the drugs, the implication is that it is the cost to the patient (or their insurer), a negative to be weighed against the potential benefit (or not) of the therapy. In this sense, it is one item on the scale. But the cost to the patient or insurer is the source of enormous profits to the pharmaceutical companies that make these incredibly expensive drugs, and they are heavily marketed to physicians by those multi-billion-dollar corporations. Their marketing campaigns push the slightest, least-convincingly-demonstrated-by-research potential benefits, and almost never talk (audibly) about the possible, probable, likely negative effects of treatment.

While these companies are the greatest financial beneficiaries, so are the hospitals and cancer centers that administer them. The reason that there are so many cancer centers is only in part because cancer is a bad disease; it is largely because it is a very profitable disease to treat because the markup paid by insurers (led by Medicare) for administering chemotherapy is very high. Doctors (particularly oncologists) benefit most directly when they are owners of such cancer centers, but to a lesser degree when they receive high salaries from their employer that are made possible by the huge profits on cancer treatment.

It is an ugly thought that your receiving cancer drugs may be in large part because the manufacturers stand to make a lot of money from it, but there it is. And it is not just cancer treatment; a recent article in the Business section of the NY Times from July 24, 2015 by Andrew Pollack, “New Drug Sharply Lowers Cholesterol, but It’s Costly”, describes the introduction of a new “recombinant DNA” drug called alirocumab (Praluent) that dramatically lowers cholesterol levels, but will cost $14,600 a year! This may be a wonder drug for the relatively small number of people who have familial hypercholesterolemia, but the indications will unquestionably be pushed by physicians with encouragement from the manufacturer. Every time there is the least evidence that a drug, initially intended for the most severely affected patient, can be used for a larger group, there is more potential for enormous profit. The evidence that just lowering cholesterol as much as can be done is linearly linked to reducing heart attack and stroke is limited. “’This is treating a lab value,’ said Dr. Rita Redberg, a cardiologist at the University of California, San Francisco, referring to lowering cholesterol for its own sake. ‘I don’t think we should rush into it.’”

“’We came to a price that is reflective of value, not what the market will bear,’ said Elias Zerhouni, head of research and development at Sanofi [one of the two companies that make alirocumab], who said his own brother had suffered three heart attacks and needed new options to control cholesterol.” I am sorry about his brother, but if you believe that, I’ve got a bridge to sell you. It is absolutely about the price that the market will bear. The sad part is that there may be some who are more willing to believe this because Dr. Zerhouni used to be the head of the National Institutes of Health (NIH), a higher-profile but undoubtedly less well-paid position. Revolving door, anyone?

Alirocumab is likely to be beneficial to some patients but will undoubtedly be used in many more and is unconscionably priced. It’s fine for a company to make profit on its drugs, but predatory pricing and rapacious profit is not. Most disturbing is the thought that people who do not need and will not benefit from a drug, and may even be harmed by it, may receive it mainly so these companies can profit.

The line I quote from Blanke and Fromme at the start of this piece refers to chemotherapy for metastatic cancer, but in fact can be applied far more generally:

In reality, only 2 reasons exist for administering therapy to patients: to help them live longer and/or to help them live better.

Let’s keep that, and not corporate profit, as our touchstone.
