A Cure For Cancer? Not So Fast

The news report in the Jerusalem Post regarding researchers’ claim that they have found a cure for cancer is certain to get our attention. And, it goes without saying, we all share the aspirational hope that they are correct. Unfortunately, we must be aware that this is far from proven as an effective treatment for people with cancer, let alone a cure.… Continue reading →

Cancer Statistics 2019: Cancer Death Rates Have Declined 27% In 25 Years, And We Still Have A Long Way To Go

Good news is always welcome, especially when talking about something as serious as cancer. And there is plenty of welcome information in the American Cancer Society’s release today of our annual report on “Cancer Statistics, 2019” and its accompanying consumer-oriented version of “Cancer Facts & Figures 2019.”

Among the good news in this report: A significant decline in death rates from cancer—especially among some of the most common cancers, significant improvements in early detection and treatment of cancer, and a decrease in the disparities in death rates between African-Americans and whites.

Despite the good news, unfortunately, there are also pieces of the puzzle that have not been solved. And to ignore that information is a disservice to those who struggle with cancer and those who have passed because of this dread disease. The reality is we can—indeed, we must—do better. And that fact is an equally important part of the information contained in this report.… Continue reading →

Times Change, Our Bodies Change, And Now The Body Mass Index (BMI) Guidelines May Change Too

A recent news story in the Journal of the American Medical Association (JAMA) reminds me that lots of things in our lives are changing these days, not the least of which is the shape of our bodies.

Oh, my. This aging thing isn’t so easy, and that is really the message behind Rita Rubin’s timely piece about shifting body mass and muscle as we age and its implications. Although focused on women, I can attest personally that men fall into the same trap as well. That 250 pounds when you are older simply is not the same 250 pounds when you were in college. Now 250 pounds looks more like 280—even though the scale still says 250. Go figure…

Although I may be trying to provide a little humor to the subject, the reality is it’s not humorous when it comes to our health. As we age, muscle turns to fat. In a process called “sarcopenia,” muscle begins an inexorable march to become fat, and for most of us it doesn’t make too much difference how much we try to forestall the shift. It is programmed into our bodies, and although exercise might help, Mother Nature simply doesn’t … Continue reading →

The Task Force Shift on PSA: It Really IS A Big Deal

Sometimes it all depends on your point of view when it comes to areas of divergent opinion about the value of certain medical tests and procedures.

So it should be no surprise that the release earlier this week of the United States Preventive Services Task Force draft statement of their new updated recommendations on the use of the PSA test to screen men for prostate cancer has generated some controversy of its own.

However, this time around it’s not just the advocates or the detractors aiming their fire at the Task Force—it’s journalists and bloggers battling over how media reports and headlines portrayed the impact and ultimate meaning of that draft report (I emphasize “draft” with more on that later). The report basically took the PSA test out of Task Force purgatory by changing the prior recommendation from “don’t do it at all” to a more permissive “have a discussion and make a decision if it’s right for you.”… Continue reading →

Chewing Gum To Detect Cancer: Reporting The Hype, Diminishing The Facts

Sometimes It’s important to know the news behind the news: the comments and the cautions that don’t get into the article that the public gets to read. It’s the sort of thing that keeps me up at night: trying to convey the reality, while realizing what most people want to hear is the hope.

That’s the problem I have with a story posted on a major news network website yesterday, where I have a brief quotation that failed to capture the thoughts I tried to express at the time of the interview. The reporter had very limited time, and the information I wanted to provide was complicated. Instead of the caution I tried to convey to counter the potential “hype” about chewing gum to find cancer early, the report suggests that this is a test that will be available soon—while failing to inform how complicated it would be to achieve that goal.… Continue reading →

Do Fitness Trackers Help Us Lose Weight? The New York Times Says “No”; I Say “Not So Fast”

I am devoted to my fitness tracker, having used it for several years to remind me to be active, monitor my diet and improve my sleep. Now the New York Times tells me it doesn’t make a difference, at least when it comes to the weight loss part of the program. And I might agree, if only the evidence they relied on told the whole story. In my opinion, it did not.

Unfortunately, some of the science on which the Times’ reporter based his comments had a possible flaw that may influence the conclusion that fitness trackers not only don’t encourage weight loss, but improbably may lead to less weight loss when using the device.

That, my friends, would be a real bummer. However, if you had evaluated that research closely you may have been aware of the problem. From where I sit, I don’t think many folks have made that effort. And I remain unconvinced that the research supports the conclusion that fitness trackers–when used in typical real-life situations–don’t make a difference in keeping us engaged in our health including as an adjunct in weight loss programs.… Continue reading →

10 Years And Half A Million Words…

I just noticed this blog celebrated its 10th anniversary this September. So I hope you won’t mind me taking this opportunity to share some observations and reminiscences of what it’s been like to document by blog a decade of the changing landscape of cancer.

The first blog was published on September 9, 2005 when I introduced the blog and my vision for what i hoped it would represent.

The blog originated with a concept developed by our media relations team. Social media was just coming into prominence, and the Society was looking at ways to get into this space. Bob Lutz, a senior executive at General Motors at the time, was the model: he wrote a regular blog himself, and was pretty open in sharing his thoughts. It was clearly not one of those ghost written, pre-packaged types of things. How he found the time to do a blog was an interesting question, but the concept was intriguing: if we could have one of our senior folks write something similar, perhaps it would get some recognition in this rapidly expanding means of communicating.

So we ventured into the space and I started writing “Dr. Len’s Blog”. One of … Continue reading →

Is It Appropriate To Offer The Public “Liquid Biopsies” For the Early Detection Of Cancer?

The recent announcement by a California company offering DNA blood tests (also known as “liquid biopsies”) for the early detection of cancer takes us to a place most of us expected we would get to, but much earlier than we are prepared for. Simply stated, our technology and rush to get new tests to market-even before we have a basic understanding of how to use those tests to improve the health of consumers–has outstripped our scientific understanding, and we ignore the implications at our own peril. [more]

First, some history:

The concept of having a blood test to diagnose cancer early is not new. In fact, I recall an international meeting about a decade ago where a lecturer predicted the diagnosis of cancer through a simple finger stick that would be sent to a lab for analysis.

Fast forward to June of 2009 when I was a guest on the Today Show and was asked to offer a closing thought telling viewers something they didn’t know about cancer. My comment was to the effect that one day in the not too distant future we would be able to find cancer cells circulating in the blood in people who didn’t … Continue reading →

Genomic Testing Reaches The Clinic: How Much Is Hope–And How Much Is Hype?

(The following blog was originally posted on MedpageToday on August 3, 2015. It is reprinted here with permission.)

 

Genomics and its impact on clinical medicine appear to be the topics du jour. The science is rapidly advancing, but our ability to understand and apply that science may not be keeping pace. The question is whether expectations will meet the promise, and are we wise enough to navigate the maelstrom and bring true benefit to our patients and consumers in general?

Three recent research reports highlight how fast some of this discovery is moving. Two reports focused on the use of cell-free DNA fragments extracted from the blood and saliva to identify cancer related markers in patients with pancreatic and head and neck cancer. The other reported discordance in DNA from mothers and their fetuses discovered when prenatal blood tests were done, again using cell-free DNA. In short, the researchers reported on situations where a prenatal screen showed abnormal DNA, the fetus was tested and showed normal DNA which then led to the discovery of cancer in the mother.

To be certain, there are many similar research reports. But they all point in the direction that we are soon … Continue reading →

Genomics May Be The New Frontier, But Knowing Your Family Medical History Is Still Very Important

It’s no secret that genomics is cutting edge science. It is exciting, it is changing the way we think about ourselves and the medical care we receive. But with all the “gee whiz” aspects of what we are discovering every day about our genetic code, it may be surprising to learn that one of the most important parts of our new tool kit may be sitting right there in front of us gathering more dust than attention.

This revelation came while attending a conference this past week sponsored by a group called HL7. HL7 develops standards for the exchange, integration, sharing, and retrieval of electronic health information in the healthcare setting. They convened this particular meeting to better understand how we can more effectively integrate genomic data into health care delivery and research so we can full advantage of the information from genomic-derived science that is coming at us like a tsunami. 

What stood out amidst all of the topics discussed-and what achieved the greatest consensus among the conferees-was the role that the tried-and-true basic family history can play in helping us understand how the information provided by genomics fits together with real life. That’s correct: the old fashioned … Continue reading →
