My other project was a collaboration between French group, Euro CCR, and UCLA group. I breed a collaboration to add the French patient with a sarcomatoid tumor to the UCLA patient with sarcomatoid tumor.
Like that, I could predict, clinical factor, we can predict a presence of sarcomatoid tumors features on pheno-pathology.
So, the main, the main factor, could influence the presence of sarcomatoid in the pathology with the current smoker. Patient who will smoke before the surgery has better risk to get sarcomatoid tumors on the pathology.
