SAN FRANCISCO, Feb. 24 (GenomeWeb News) - Despite recent advancements in molecular diagnostics, insiders from industry and academia sounded a cautious note when describing the state of the industry during Cambridge Healthtech's Molecular Medicine Tri-Conference, held here last week.
Jorge Leon, the acting chief scientific officer of Orion Genomics, said during a presentation that, in particular, "the cancer diagnostic market is really pathetic."
"There is a great need for breast and ovarian cancer screening diagnostics," said Leon. Orion, based in
"I think the tests we have available show poor performance; they don't provide useful information in the clinical setting," Ioannidis told GenomeWeb News after his talk. "For most diseases we are almost at a loss."
According to David Ransohoff, an epidemiologist at the
He said that many companies are led into thinking that discovery is easy, and that many studies that result in diagnostic efforts "don't give reproducible results."
"The field has got to organize itself more in a way parallel to how drugs are developed," Ransohoff said. "We need to design studies that are reliable and we can build on. If the units of knowledge in the field are not strong then the field cannot solve these problems."
Ultimately, though, Ransohoff said he thinks "people are going to look back on this as a naïve and inefficient time."
"People will look back at this time and say that the mistakes that we have made could have been predicted," he said.
However, Ransohoff and others pointed out that there is some good work being done. He said that the success of Genomic Health in developing the OncotypeDx test for breast cancer recurrence has "outlined a kind of model that the field can learn from."
Ioannidis added that "progress in the field will be incremental."
"[Our] faith stems from the fact that we can measure a lot of things," he said. "But the answer is buried somewhere in the data. Finding the answer is the problem."
