Age related differences in primary testicular lymphoma: A population based cohort study

•We have 2 cohorts: 1) PTL patients diagnosed between 2000 and 2017 and 2) PTL patients diagnosed between 1983 and 2017 (lower sample size as this is from a registry that includes lower number of US states). We hoped that cohort 1 would reflect a more contemporary cohort which would have received R-CHOP treatment for PTL.•We stratified patients by age ≤50 and >50. We hoped this would make this a stronger paper and different from previous similar study that used age 70 as cut-off to stratify patients.
