  • Surveillance...Just don't understand the Math

    Hi All,

    Here's a question... If Stage I Seminoma is 95% survival after 5 years, and Stage II seminoma is only 70%-90% survival, then why is it that people on a surveillance protocol still supposedly have 95% survival? In other words, if I'm on surveillance and relapse, will I not have progressed to Stage II disease to treat the relapse?


    Detected mass 10-6-06, Radical left I/O 10-10-06, Stage I seminoma, 1.5 cm primary, No LV invasion, No Rete Testis Invasion... Currently on Surveillance.

    My asumption is, Because usually if your 1st diagnosed with stage 2 the spread is large tumors and the cancer is usually a faster seminoma.
    But, if you get upstaged to stage 2 during survalience they see the tumours while there small and for you to be initialy diagnosed as stage 1 then the seminoma would more likely be less agressive.

      It's because so many people on surveillance are already cured and never do have a recurrence.
      right inguinal orchiectomy 6/5/2003 > nonseminoma, stage I > surveillance > L-RPLND 6/24/2005 for recurrence, suspected teratoma but found seminoma, stage II > chylous ascites until 9/2005 > surveillance and "all clear" since

        These numbers can be tricky to understand but Scott is right. What they are saying is that 95% are cured right away. Of the 5% that relapse the cure rate is 70-90%.
        Son Jason diagnosed 4/30/04, stage III. Right I/O 4/30/04. Graduated College 5/13/04. 4XEP 6/7/04 - 8/13/04. Full open RPLND 10/13/04. All Clear since.

        Treated by Dr. Rakowski of Midland Park, NJ. Visited Sloan Kettering for protocol advice. RPLND done at Sloan Kettering.
