How has hematology changed since your experience caring for that patient?
That was in 1985, when we had no clue about the genetic basis for diseases like myeloid leukemias or myelodysplastic syndrome. We could see translocations through cytogenetics, but we did not know whether those translocations were causal or what genes were involved in them. This also was more than a decade before the first version of the human genome sequence was released.
Today, of course, we have a near-complete catalog of every single mutation that contributes to the development of leukemia. For me, it’s exciting to have come from a time when we didn’t know the identity of a single gene that caused acute leukemia, to today, when we know what those genes are, how they function, and how we can target those genes and reactivate the immune system.
We’re able to help patients in new ways. We can take the progress that has been made about the genetics and molecular biology of the cancer itself – how the tumors are able to suppress the immune system and how we can override that to the benefit of patients – and translate those into clinically meaningful advances for our patients.
And, though I’m a bit more removed from the clinical frontlines than I used to be, part of the joy of being in hematology today is hearing from patients whose disease – which they were told was fatal – is responding well to the treatment they’re receiving at our center. When patients or their family members stop by my office to say thank you, it puts a lot of sunshine into any day, which counts for a lot in Seattle.
Now that the opportunity is there, what do you think are the barriers to bringing these curative approaches to patients?
There are a broad range of challenges for us. One, of course, is the complexity of the science. We need a deep understanding of the DNA sequence, the expressed gene products, and the epigenetic changes that happen in cancer. We are generating massive datasets; now we need to develop the analytic tools to integrate terabytes of data with clinical patient information to understand how the data and the sequence relate to each other.
Funding issues are a serious concern, as well. I spend more time than I’d like working with our legislators on this issue. Generally, we enjoy wonderful bipartisan support on medical research funding. However, when ill-advised policymakers suggest that we should be cutting the NIH budget by 18 percent at a time when we are at an inflection point in developing curative approaches to cancer, that is a travesty – and, in my opinion, unconscionable.
Policymakers appear to be attacking the finance of administration rates and the real costs of doing research. Recently, I testified before the House Appropriations Committee on what the indirect cost rates are, their importance, and why we can’t cut them. We will ultimately get to the point where we are curing cancer, but cutting funding means we will get there slower. There are people who died from cancer while I was testifying on the Hill; that’s the sense of urgency that we need to feel going forward.
There also is a bit of a mental obstacle to overcome among hematologists who have been in the field for a long time. We have been stuck in the frame of mind that, based on everything we have witnessed in clinical practice, once a patient’s cancer become metastatic, it can’t be cured. We use the euphemism, “We can treat your cancer†– the implication being that we can’t cure it. But, today, we can say that there are curative approaches for some of our patients.
