Who Will Lead Us As We Embrace Personalized Medicine And Cancer Care And Turn The Tide Against Cancer?

Earlier this week I had the opportunity to attend and participate in a conference “Turning the Tide Against Cancer Through Sustained Medical Innovation” in Washington DC. . The conference organizers brought together a stellar list of experts (present company excepted) to discuss the coming revolution in cancer care through personalized medicine, as well as the barriers and risks we face as science moves us forward towards what I consider a brave new world of cancer research and treatment.

 

With all of the intellect that was present at that meeting-and there was a lot-there was a theme that crystallized for me and others as the day progressed: we have developed incredible science and incredible opportunities to understand and treat cancer. But with all of the issues that have to be dealt with, the reality is that there is no singular leader-organization or individual-who has the clout and the heft to accelerate all the changes that need to happen if the vision of personalized medicine is going to be a success.

The progress we have made in the laboratory over the past 40 years has been truly incredible. As I have written previously, we have learned much about what … Continue reading →

Through The Fog Of New Cancer Research Information, The Enthusiasm Of Youth Meets The Wisdom Of Elders

I had trouble sleeping this morning, so I got up and took a look at the tweets on my smartphone that focused on yesterday’s sessions at the annual meeting of the American Society of Clinical Oncology in Chicago.

 

There were literally hundreds of bits of information that covered the span of sessions, from science to quality of life to other topics of interests. I wondered how much of the information we have heard over the past several days will actually make a difference in the lives of cancer patients in the days and months ahead. And while sitting in a less well-attended session hearing an update on another once promising approach, the sad reality struck me squarely: not much.

 

This is the premier clinical cancer meeting in the country, if not the world. Thousands of doctors and researchers come to this meeting to learn the latest information about clinical cancer research and cancer treatment. There are thousands of abstracts presented and discussed, and constant chatter about the newest drug or the newest test or the newest way to diagnose cancer. The drug companies, the lab test companies, the computer companies are all here to advance their drugs and … Continue reading →

Genomics Leads To An “Aha!” Moment And Closes The Loop On Tanning Beds And Melanoma Risk

Yesterday I wrote a blog discussing how meetings like the current annual gathering of the American Society of Clinical Oncology (ASCO) gives me a chance to think about big picture questions.

 

Well, there is another side to the experience that is also interesting and important, such as getting information that helps put together pieces of a larger puzzle, and perhaps even gives closure to a nagging question. When you have one of those “Aha!!!” moments, it can truly solidify your thoughts and maybe even save a few lives in the process. In this case, the same presentation that led to yesterday’s comments about the emerging complexities of the diagnosis of cancer also produced another enlightening moment.

 

Dr. Levi Garraway is a highly regarded genomics researcher from Dana Farber Cancer Institute in Boston who presented a lecture on the topic of how genome sequencing is bringing new insights to the biology and treatment of cancer. As part of his presentation, Dr. Garraway offered information on areas where genomics has already offered us definitive information that has direct implications in understanding cancer.

 

The #1 item on Dr. Garraway’s list was a topic of intense interest to me and several … Continue reading →

Will Genomics Lead Us To A Brave New World Of Cancer Diagnosis?

 

One of the things I enjoy about coming to meetings like the current annual session of the American Society of Clinical Oncology (ASCO) is that it gives me a chance to give thought to some larger questions that face cancer care. A presentation I attended Friday afternoon on the impact of genomics on cancer diagnosis and treatment in the future has offered just such an opportunity.

 

Most of you I suspect give little thought to the actual processes that we use to diagnose cancer. One has a tumor somewhere in the body, the doctors take a specimen, send it to the pathologist and the pathologist makes the diagnosis. Simple and straightforward. Get it done and get on with treatment.

 

But in fact it isn’t so simple and straightforward. And in the world we live in, it is getting more and more complex.

 

Looking at cancer tissue under the microscope is something that has been done for over a century. More recently, we have seen the advent of special additional tests that tell us for example whether or not a cancer such as breast cancer is hormone sensitive or whether it has other markers such as HER2. … Continue reading →

A Blast From The Past Meets A Drug From The Present To Create A Vision Of The Future: A New Treatment For Breast Cancer That Makes A Difference

 

This is the stuff of science fiction, a dream, something you could envision but were skeptical it could be done. But now it has been done, and raises the question of whether we are headed “back to the future” in the treatment of cancer.

 

The drug in question here is called T-DM1. It is an “antibody drug conjugate” between trastuzumab–which is a monoclonal antibody drug commonly used today to treat selected women with aggressive breast cancer–bound to a derivative of another more traditional cancer chemotherapy drug called maytansine.

 

Maytansine was a cancer chemotherapy drug evaluated in the 1970’s and found to be effective in treating breast cancer, but its side effects were so severe that it could not be used clinically. As a result, it became a laboratory curiosity, banned from patient care.

 

Trastuzumab is one of the really positive stories of the modern targeted therapy era. It is an antibody drug that has effectively treated women with advanced breast cancer that is positive for HER2, which results in a protein “key” being formed on the surface of certain breast cancer cells. Trastuzumab attaches to that key and aborts the internal processes … Continue reading →

Promising New Approach To Treating Cancer Means Hope For Many, But Remember This Is Just The Start Of The Journey

Every year at this time cancer specialists and researchers from around the world descend on Chicago for the annual meeting of the American Society of Clinical Oncology (ASCO) to hear the latest breakthroughs in cancer research and treatment.

 

Through all the fog of all the information–which is impossible for any one individual to evaluate much less comprehend–there is always the search for the “buzz,” or the next “big thing” that will make a huge impact on cancer treatment and the lives of the patients we care for and the people we love who are affected by cancer.

 

This year, it is apparent already that one of this year’s “big things” are the reports of new success in an old and ongoing effort to harness the body’s own defense mechanisms to fight cancer. And–being the skeptic that I can be at times–I will throw my hat in the ring that maybe this is going to be one of those events that truly will impact cancer care. But despite the enthusiasm, we must always temper our expectations with reality and lessons we have learned from the past that early success doesn’t always tell us the whole story.
