Holy Grail or holy sh..t? Very intriguing results from the PATHFINDER-2 trial with Galleri MCED test - trial does not reach its endpoint (of reducing n of 12 index st 3/4 cancers by 3 yrs) but still… notable separation of stage 4 cancer detection curves at 3 yrs+ so maybe endpoint was overoptimistic/too early? Despite very high specificity, low prevalence yields more false neg than true pos results so similar to scanxiety…. With MCED tests we will run risk of creating a new emotion: MSAD…
In a trial of a blood-based multicancer early-detection test added to usual care, the incidence of stage III or IV cancer after three rounds of screening did not differ significantly from that with usual care alone.

File this under reviews that will change your perspective. And for the #molpath community, please help me wrap my head around how we can detect the alterations depicted in Fig. 4C. @TheNixonLab rdcu.be/fy0He

RET mutations are the most common molecular alterations in MTC in both somatic and familial MTC, very important in treatment with target RET inhibitors, second common is RAS mutations #cytochat @CancerCytopath @bfaquin @MarcPusztaszeri @IvanaKholova @MichiyaNishino
