Field notes
The interface asks for histology and pathology details such as lymphovascular invasion, embryonal carcinoma, and selected pre-orchiectomy lab results. A time-since-orchiectomy input supports a conditional estimate for someone who has remained relapse-free to that point. The cited Danish models cover patients diagnosed from 2013 to 2018, with follow-up to 2022; the page also compares findings from other named cohorts.
