What are the Epidemiologic Signatures in Cancer? A new special report out in NEJM by Gil Welch, Barnett Kramer, and William Black is so good I had to do a #tweetorial. πŸ‘‡πŸΎπŸ‘‡πŸΎπŸ‘‡πŸΎ
Special Report: Epidemiologic Signatures in Cancer
The US epidemiological story of #cancer 1975-2015, a mixed story of the good after reduction of cigarette smoking and the bad on rising incidence/ "side-effect" of early detection
#CML and #Hodgkin disease epidemiology When there is a real improvement in #cancer care, mortality decreases while incidence remains stable (CML and HD). If both have reduced, a risk factor was addressed (smoke & lung cancer) Look at this πŸ‘‡πŸ‘‡πŸ‘‡
Early detection is a gigantic shruggee. Great to see Welch back!
This recent article in is really relevant to this β€” detecting more cancers is not the same as curing more cancers.

These epi "signatures" of cancer incidence and mortality really help illustrate the population-level effects of screening, treatment advances, and overdiagnosis of indolent disease. Simple, yet useful visualizations.
neither these authors nor the prior paper's authors present the mortality rate per 100k over time. If they did that, they would know the answer. They could look up the pattern here: Gil welch would have a stroke reading this.
Always interpret cancer incidence in concert with mortality. A stable incidence and falling mortality is a strong signal of improved Tt. Likely the case with MM Epidemiologic Signatures in Cancer | NEJM
β€œA sustained increase in incidence coupled with stable mortality, however, suggests something fundamentally different: overdiagnosis superimposed on stable true cancer occurrence.”

Nice overview of cancer incidence vs. mortality decline. Overdiagnosis vs. true improvement #radonc
