Awards for Connie Eaves and John Dick

Canadian stem cell researchers Eaves and Dick to receive hematology awards, Michael Rudnicki, Stem Cell Network blog, July 31, 2009. Excerpts:
Connie Eaves, PhD, of the BC Cancer Agency, University of British Columbia in Vancouver, will be presented with the Henry M. Stratton Medal, which honors an individual whose well-recognized contributions to hematology have taken place over a period of several years. Dr. Eaves will receive this award for her remarkable achievements in the area of stem cell biology for more than two decades. Dr. Eaves has been on the cutting edge of adapting or introducing technologies related to stem cell biology, especially her ground-breaking techniques of using the long-term culture system as means of understanding the proliferative and renewal properties of normal and malignant primitive human hematopoietic stem cells.
John E. Dick, PhD, of the University Health Network in Toronto, will be recognized with the E. Donnall Thomas Lecture and Prize for his pioneering research into the development of human leukemia, which has transformed the view of how leukemia progresses. This prize, named after a Nobel Prize laureate and past Society president, recognizes pioneering research achievements in hematology.
These summaries were obtained from: Six Researchers to Receive Prestigious Awards From the American Society of Hematology, Press Release, American Society of Hematology, July 13, 2009.

Comment: Very appropriate recognition of accomplishments in hematological research that have included important contributions to cancer research.

Lecture on stem cells and cancer

The 2009 Summer Symposium of the David H. Koch Institute for Integrative Cancer Research of MIT was on Understanding Metastasis. The Symposium was held on June 19, 2009. One of the lectures in the morning session was on "Stem cells and cancer", by Sean Morrison (University of Michigan) [FriendFeed entry]. A video (35 min) of the lecture can be accessed via the program. One example of a noteworthy slide is the one that's shown for 10 seconds, from 28:38 to 28:48 (entitled: "Nobody has yet tested which cells actually contribute to disease in patients"), in which it's pointed out that the "Fate of cells within patients is unclear ...".

Another lecture, at the same Symposium, addresses this issue (within the context of the theme of the Symposium, "Understanding Metastasis"). It's "Monitoring the fate of cancer cells during metastasis", by Ann Chambers (Regional Cancer Center, London, Ontario). A video (25 min) of her lecture can also be accessed via the program.

Grant system good at ruling out bad things?

Grant System Leads Cancer Researchers to Play It Safe, by Gina Kolata, The New York Times, June 27, 2009. [Page 1][Page 2][Page 3][FriendFeed entry].

Excerpts from Page 1:
Yet the fight against cancer is going slower than most had hoped, with only small changes in the death rate in the almost 40 years since it [the "war on cancer" initiated by President Nixon in 1971] began.
One major impediment, scientists agree, is the grant system itself. It has become a sort of jobs program, a way to keep research laboratories going year after year with the understanding that the focus will be on small projects unlikely to take significant steps toward curing cancer.
.....
Even top federal cancer officials say the system needs to be changed.
“We have a system that works over all pretty well, and is very good at ruling out bad things — we don’t fund bad research,” said Dr. Raynard S. Kington, acting director of the National Institutes of Health, which includes the cancer institute. “But given that, we also recognize that the system probably provides disincentives to funding really transformative research.”
Excerpt from Page 2:
“They said I don’t have preliminary results,” she said. “Of course I don’t. I need the grant money to get them.”
Excerpt from Page 3:
Some experienced scientists have found a way to offset the problem somewhat. They do chancy experiments by siphoning money from their grants.
Comment: The focus of the article is on the grant funding system for cancer research in the USA. The author, a well-known science journalist, is pessimistic about the success that the current funding system has had in yielding research outputs that have led to any substantial decrease in cancer mortality rates. However, other than briefly mentioning overall cancer mortality rates, she does not attempt to analyze current approaches to cancer control.

In Canada, age-standardized mortality rates, for all cancers and all age groups, have decreased from 248/100,000 in 1984 to 212/100,000 in 2004 (about 15%) for males. In contrast, the corresponding mortality rates for Canadian females were 152/100,000 in 1984 and 147/100,000 in 2004 (a decrease of only about 3%). A detailed analysis is beyond the scope of this brief commentary, but a major reason is that age-standardized mortality rates for respiratory cancers have been higher in males and have been decreasing, while they have been lower in females, and have been increasing.

It has been estimated that, in the USA, "reductions in lung cancer, resulting from reductions in tobacco smoking over the last half century, account for about 40% of the decrease in overall male cancer death rates" (Tobacco Control 2006; 15: 345-347; doi:10.1136/tc.2006.017749). Strong evidence that tobacco smoking and lung cancer rates are related has been available for more than 50 years, since the research work of Richard Doll and Austin Bradford Hill.

We now know a great deal about success stories and best practices for effective, evidence-based tobacco control programs. (See, for example, Success stories and lessons learnt, Tobacco Free Initiative (TFI), World Health Organization).

So, does research play a crucial role in cancer control? Of course it does.

Can it take a very long time for research outputs to have a substantial impact on cancer control? Unfortunately, it can.

Do we have good ways to identify, in advance, areas of transformative research? Unfortunately, no. It can even take a long time to demonstrate that certain research has, indeed, been transformative.

So, what to do? My answer: investment in research is much like investment of venture capital. Only a very small minority of investments yield a big payoff, but one can predict much more easily which investments are likely do badly than which ones are likely to do well.

Article in The Scientist

How to win the war against cancer by Frank L Douglas and Robert E Litan, The Scientist, November 5, 2008 [free registration is required]. Excerpt:
We now know from many areas of science -- including cancer research -- that collaborative research by investigators with different but complementary areas of expertise are more likely to crack difficult problems than "lone rangers" who work in isolation. With more cooperation and less competition in cancer research, the war against cancer is much more likely to be won.
Over the past month, this short opinion article has attracted a number of comments from readers. An example: "Competition vs. collaboration" by an anonymous poster, November 10, 2008. Excerpt:
Therefore big bucks should be spent by the NIH on big projects, but these projects should have a purely supportive role (core facilities, tissue banks, high-throughput assay systems, result databases) and the people involved should be paid enough to make up for decreased career opportunities, which working in such supportive roles would entail. Enticing people to collaborate just because there is money in collaborating is going to just result in a lot of people flocking around the trough and pretending they have some common goal, while in fact they will be doing disparate things under a makeshift common banner.
Another example of a comment: "Doubtful strategy" by Rainer Zahlten, November 7, 2008. Excerpt:
This "new" strategy is bound to fail. Why? Because enforced cooperation for the sake of obtaining research grants is counterproductive to a physiologic matching of research interests, including a viable chemistry between participating scientists.
