Are Older Persons Being Over Treated for Nonmelanoma Skin Cancer?


One could argue that nonmelanoma skin cancer should not even be called Cancer.  While under the microscope it looks like cancer, it doesn't really act like what most people think of when they hear the word, "Cancer."  Unlike the much less common melanoma or cancers of other organs, plain old run of the mill skin "cancer" almost never metastasizes (ie, spread to different organs).  It usually grow very slowly, and is almost never fatal.  Often it is asymptomatic and has no impact on quality of life.  This condition just does not deserve the dread and fear associated with word, "Cancer."

Since nonmelanoma skin "cancer" usually poses no threat at all to survival, the reason to treat the "cancer" is to improve well being.    We can enhance well being by treating a "cancer" that is currently bothersome to the patient, or will become bothersome if it grows and expands.  But this is where it gets interesting.  Since many of these "cancers" grow very slowly, some will never become problematic in the patient's lifetime.  This is a very important consideration as skin "cancer" is predominantly a disease of older people.  Many persons with skin "cancer" are very old or very frail.  Patients with limited life expectancies may do fine with either minimal treatment, or perpaps even no treatment at all.  This suggests that the best treatment for a particular "cancer" needs to consider the age and health status of the patient. 

But, in actual practice, when a patientt has skin "cancer", does the treating provider consider the individual characteristics of the patient in front of them, or do they use a one size fits all approach, focusing on the "cancer", but not the person?

A fascinating study in JAMA Internal Medicine suggests we are overtreating skin "cancer" in patients who are very old or very frail because of a one size fits all approach to treatment.  The study was led by Dr. Eleni Linos, with senior author Dr. Mary-Margaret Chren, both Dermatologists at UCSF.  They examined treatment of patients with nonmelanoma skin "cancer" at UCSF and the San Francisco VA.  They did a very interesting comparison of how skin "cancer" treatment varied in patients with long vs limited life expectancies.  The limited life expectancy group included persons over the age of 85, or with many medical conditions. 

They found:

  • Patients are almost always treated.  The no treatment option was chosen for only 3% of skin "cancers".  Of note, 60% of "cancers" were not on the face, and in only 22% of cases were patients significantly bothered by their "cancer", suggesting that very conservative management of deferred treatment should have been reasonable in at least some patients.
  • Patient characteristics are not considered in the treatment decision.  There are a number of treatment options for patients ranging from very simple and less invasive options like destruction (i.e., freezing) to surgical options.  The most invasive option, Moh's surgery was used in 34% of patients.  Moh's surgery takes on average 3 hours and is also the most expensive option.  Patients with long life expectancies and short life expectancies were equally likely to get Moh's surgery.  Thus very advanced age or severe co-existing disease seemed to make not one iota of difference in treatment. 
This study suggests we need to revisit how we treat skin cancer, especially in the very old.  Perhaps we should at least inform patients that deferring treatment may be a viable option.  When treatment is deferred, patients have the option of getting treated later if they change their mind, or the skin cancer seems to be growing.  When the skin cancer is treated, patients need to have more of a say in their treatment options, and given the choice of less invasive and bothersome treatments with less risk of complications.

Lumping all non-melanoma skin cancers into one group is as dangerous as it is erroneous. While basal cell carcinomas are usually slow growing and not life threatening, squamous cell carcinomas that originate in the skin can and do metastasize to other organs and can be deadly.

Cognitive psychologist and Nobel prize winner Dan Kahneman suggests that when someone asks a question that is too hard (like "are the benefits of treating skin cancer in frail older adults worht the risks and costs?") that we as humans substitute an easier question (like "is cancer bad?" or "do I like cancer?")

Toni Kamins, you have done exactly this with your comment. You have substituted a thoughtful cognitive question regarding the treatment of skin cancer with an emotionally laden question of "is cancer bad?"

This is one of the problems with the entire field of cancer prevention. Any time someone poses a thoughtful question about trade-offs, which is hard to think about, the backlash always relates to the easier question and turns into a thoughtless, emotionally laden journey into "cancer is bad."

Yes, cancer is bad...but that's not the question...

So annoying.

I forwarded this post along to my dear friend and dermatologist extradinaire shared with me a wonderful story that really exemplifies the ethos of this geri-pal post. An very elderly patient came to see her for the first time. As he removed his ball cap she was stunned to see anenormous squamous cell lesion that covered most of the top of his head. His arms were simply emcrusted in cancer. Not even sure where to begin she said to him "What is bothering you today" His daughter was clearly troubled by the large lesion on his head. He pointed to a single 1 cm lesion on his arms that was itching. Then they had a thoughtful discussion about the risks and considerable burdens of treating the other skin cancers ("Cancer?! the patient exclaimed)and then decided to simply freeze the one arm lesion that was itching. he left her office smiling, slipping his ball cap back on his head.

Clearly you misread my post and inferred according to your own agenda. So annoying.

Caring, and the Family Caregivers We Don’t See

Over lunch at a restaurant in Manhattan, my father and I talked about long-term care insurance and the emergence of senior centers and nursing homes across the U.S. that offer a variety of ethnic cuisines and cultural events, catering not only to a growing population of adults over 65, but also, to an increasingly diverse population of adults who call the U.S. their home. This conversation was different from many similar ones before it – we weren’t talking about my research; we were talking about our own lives.
My parents immigrated to the U.S. in the late ‘70s and early ‘80s, following their parents’ advice on professional opportunities that seemed unimaginable in India at the time. Although they considered moving back soon after to care for their aging parents and to raise children, they ultimately decided to stay in the U.S. As I chronicled earlier, my paternal grandparents lived with us until I completed middle school, at which point they returned to India and lived with my mater…

Practical Advice for the End of Life: A Podcast with BJ Miller

This week we talk with BJ Miller, hospice and palliative care physician, public speaker, and now author with Shoshana Berger of the book "A Beginner's Guide to the End."

As we note on the podcast, BJ is about as close as we get to a celebrity in Hospice and Palliative Care.  His TED Talk "What Really Matters at the End of Life" has been viewed more than 9 million times.  As we discuss on the Podcast, this has changed BJ's life, and he spends most of his working time engaged in public speaking, being the public "face" of the hospice and palliative care movement.

The book he and Berger wrote is filled to the brim with practical advice.  I mean, nuts and bolts practical advice.  Things like:
How to clean out not only your emotional house but your physical house (turns out there are services for that!)Posting about your illness on social media (should you post to Facebook)What is the difference between a funeral home and mortuaryCan I afford to die?  …

Top 25 Studies in Hospice and Palliative Care (#HPMtop25)

by: Kara Bishoff (@kara_bischoff )

Back in 2015 we wrote a post asking for input on what articles should belong on a list of the top 25 articles in hospice and palliative care.   We decided to focus on hospice palliative care studies and trials - as opposed to review articles, consensus statements and opinion pieces.

Here’s what we came up with. It was hard to pick just 25! We highly prioritized clinical utility and tried to achieve diversity & balance. Many others are worthy of inclusion. Take a look and let us know if you have suggested changes for next year.
