Complementary approach to discovery would change rules of the game

A few weeks ago, I traveled to Washington, D.C., to attend a National Cancer Policy Forum-sponsored workshop, titled “Informatics Needs and Challenges in Cancer Research.”

I was interested in the content — how can we integrate and make sense of the vast amount of continuously generated cancer-related data — as well as the individuals involved. The vice-chairwoman of the conference was Amy P. Abernethy, MD, of Duke University School of Medicine, one of my mentors and a visionary in the area of rapid-learning cancer care. All of the other speakers — from academic thought leaders to authors to industry executives — had extraordinary insights, as well.

One of the presenters — Atul J. Butte, MD, of Stanford University School of Medicine — gave a particularly provocative talk. In our current environment, he said, tremendous amounts of data already are stored and available in the public domain, and virtually all parts of scientific research can be commoditized. With a few mouse clicks, Butte showed how interested individuals easily could access public-domain gene expression profile datasets and — funds permitting — could outsource laboratory research, including animal models, to test hypotheses.

Pointedly, he paused before declaring the only thing that could not be commoditized is the ability to ask good translational questions. Half-jokingly, he wondered, if computer, IT and Internet companies could be started in garages, are we really that far away from a garage biotech?

Many of Butte’s comments clearly were meant to be thought-provoking rather than taken at face value, but they raised important questions. If the core asset in scientific inquiry is intellectual capital, how much untapped potential exists around us every day?

Some possibilities:

  • Clinicians who derive biological insights from patient care but lack a laboratory (or even “dry lab”) presence or partnership to drive insight to discovery.
  • Scientists outside of medicine who can think of new ways to approach old problems.
  • Patients, families or friends — think of PatientsLikeMe (www.patientslikeme.com) — who want to contribute to solving the diseases that afflict them.

From data to discovery

Indeed, lots of the data to get us started on fundamental questions, or even real-world clinical problems, already are available. They just need to be put together in the right way.

Last year, Butte published two articles in Science Translational Medicine in which he matched disease gene expression signatures and drug gene expression profiles and came to some surprising conclusions. Could an anti-seizure drug work in inflammatory bowel disease? An anti-ulcer drug for lung adenocarcinoma? Additional studies are under way to validate these possibilities.

Recently, I attended another lecture — this time by one of Butte’s mentors, Isaac Kohane, MD, PhD, of Children’s Hospital Boston — at a personalized medicine symposium.

In a more immediately clinically relevant example, Kohane showed how aggregating the entirety of clinical observational data from Boston-area hospitals during the past several years demonstrated a surprising spike in heart attack incidence that then went away nearly as quickly as it came on.

The clear correlates, in retrospect, were the introduction and withdrawal of rofecoxib (Vioxx, Merck) from the market. Again, the common denominator of this example and others was the initiative and ability of a creative individual to translate insight to discovery, using data and tools already available.

I’ve been mulling over these talks as I’ve been scanning my Twitter feed today. This is the weekend of the American Association for Cancer Research conference (March 31-April 4), at which many of the “big ideas” in cancer are being presented and discussed.

I wrote about Twitter in my last column. This and other social media outlets have become, in a way, a modern-day equivalent of the European coffeehouses that ushered in the Age of Enlightenment.

Traditional institutional barriers dissolve as ideas and insights from thinkers everywhere, within and outside academic medicine, flow freely with astonishingly rapid speed on virtually any topic, cancer certainly included. In some ways, Twitter is a virtual and continuous scientific meeting on any topic of the reader’s choice. Sometimes, the virtual and the on-the-ground meetings coincide, as they have today when many of the tweets and posts that I see are largely revolving around the data and lectures being unveiled, in real time, at AACR.

Earlier today, one of the AACR attendees observed the enormity of the activity ongoing in the convention center and tweeted: “You’d think … we would’ve already had a cure.”

Provocative questions

On the one hand, cancer-related scientific discovery — in the lab, translationally, and in the clinic — is on the threshold of a potentially very exciting era.

The book The Emperor of All Maladies by Siddhartha Mukherjee, MD, PhD, is emblematic of a willingness of the cancer community to engage with big, paradigm-shifting ideas. As he documents well, the greatest progress in the past has come from risk-taking rather than incrementalism.

As tangible evidence of this approach, the NCI has launched its Provocative Questions Project — available at http://provocativequestions.nci.nih.gov — that promises to “identify perplexing problems to drive progress against cancer.”

Among these questions are:

  • How does the lifespan of an organism affect the molecular mechanisms of cancer development?
  • Can we use our deepening knowledge of aging to enhance prevention or treatment of cancer?
  • How does obesity contribute to cancer risk?

One of my colleagues recently submitted a proposal for grant funding to address one of these questions, and many, many others are presenting within the convention halls in Chicago at AACR.

On the other hand, it seems that despite our willingness to tackle larger questions, we remain constrained by many of the usual barriers within our traditional infrastructure. These include challenges in sharing data or approaches with others because of competitive concerns around funding or publications; a desire to achieve personal or institutional credit; incentives to pursue incremental rather than transformative research, and to pursue the same themes rather than new directions, as the safest route to continued funding; external pressures to study specific pathways or compounds; and an inability to access the large untapped reservoir of intellectual capital that resides within clinicians, non-medical scientists, patients and other parties, as well as an inability to properly make use of large amounts of already available biological and clinical data.

So here, then, is another provocative question: What if we imagined a new, complementary approach to cancer-related scientific discovery, a utopia that could mirror the scope and pace of Twitter-like social media or community “wikis” with “crowd-sourced” questions and “crowd-sourced” answers?

The rules of the game would need to be very different. Everyone would need to share everything with everyone else in real time. In this space, the usual individual goals of prestige, funding and publications would need to become secondary or maybe not even relevant. Anyone could contribute, and by significantly expanding the breadth of involved individuals for any given problem, specific skills could quickly be brought to bear on particular aspects of the issues.

To do this, individuals with specific resources — such as laboratory experiments, bioinformatics computational tools or clinical observational data — would need to contribute when required to help the cause. Versatile thinkers would need to be able to shift focus quickly and frequently as the important questions change and evolve. To drive this effectively, those involved would need to be motivated by a deeply aspirational goal — a community-held mission to dramatically improve the care of cancer patients within our lifetime — akin to eliminating HIV in sub-Saharan Africa, or, in an earlier era, putting a man on the moon.

This vision raises many questions that are difficult to answer. What are the limits of altruism? Who would pay for the research, and how? What entity would be credited if any of the efforts are successful? What format would the endeavor take, and who would oversee and manage it? What strategy could be used to tap the reservoir of intellectual capital that needs to be tapped, to engage the minds that need to be engaged?

At this point, I don’t have any answers to these questions. But it’s a provocative idea, isn’t it? Who wants to help?
