  • Adjuvant Chemotherapy BEP: Collection of Research, Studies, Links, Probabilities...

    Hi All,

    I am currently between treatments, adjuvant chemotherapy is likely to start soon... I did a lot of research on this topic, and just wanted to share links to some links that I have collected.

    I hope you find this interesting, but I have learned that all the statistics and probabilities don't really mean much for me. You have to live with your decision and it basically comes down to personal preference. If you are willing to accept a 30 - 50% relapse risk, then you are fine on surveillance; for someone like myself, even a 10% chance would be too much to bear. I rather kill this thing now (maybe it is already gone completely - that's the 1m question) than haev to have 3 or 4xBEP later on.

    I am happy to share thoughts and all the information I could gather so far, if anyone needs support.

    Best,
    Alex

    Most recent Scandinavian stuff.
    Reassuring as BEP x 3 starts tomorrow for PA recurrence detected at 1 year follow up.

      Wow! Thank you for sharing your studies sir! Im stage 1 no lvi strongly leaning toward 1 or 2 BEP.
      November 5th noticed huge/heavy Right Testicle.
      AFP 159
      November 8th 2013 - Right I\O
      November 13th CT Pelvis AB and Chest negative
      AFP 56 NO lymphatic/vascular invasion.

      High Risk 50% Embryonal Carcinoma, 40% Teratoma, 10% yok sak.
      Nov 21st AFP 28- Thinking 1 cycle adjuvant BEP
      Currently Torn between surveillance and 1 cycle of BEP!
      Much thanks to everyone in this forum!

        I had a single cycle of adjuvant BEP last year (in the 111 trial) despite what has happened and the complications,I'd still do it again as it's better than tossing a coin waiting for your recurrence on surveillance only.
        Are you in the UK?
        If so,pm me as I am and and can then chat.

          1 cycle BEP experience

          I had 1 cycle of BEP from 5 Aug to 26 Aug this year. I could not live with the 30 - 40% chance of relapse in my case even though the oncologist said we could go with surveillance if I wanted. The latest Scandinavian study results posted above are very reassuring indeed that 1 cycle adjuvant BEP is a good option. Of course, this is a very personal decision and there is no right or wrong, just depends on your preference. For me, the additional absolute risk reduction of 2 - 2.5% (from say 3.5% to 1%) with 2 cycles is tiny, and does not compensate sufficiently for the increased level of toxicity (if 2 cycles would provide 100% guarantee it would be a no brainer of course). Also, should there be a relapse (which we all hope we never experience!), then an additional 3 cycles seems heavy with 2 prior ones, that would be a cumulative cisplatin dose of 5 rounds, also the Bleomycin would most likely have to be substituted with Ifosfamide, 5 rounds of Bleo I don't think your lungs would withstand that...

          With regards to chemo, I have to say I expected it to be worse. However, also these experiences are very personal and can vary immensely from human to human... I did not have to throw up once (I only needed Aprepitant which is standard, and lots of Motilium, no Zofran), but of course there is a feeling of sickness, you just don't want to eat or drink, and if only very selective foods and fluids, I am sure this very individual. For some reason I could only eat a particular frozen Pizza for a week, but so what... chemo is not a time for healthy diet. The fatigue and tiredness is heavy, I was surprised how it knocks you out. However, also that was kind of OK because I just slept for 15 or 18 hours a day and the sooner it was over. The one thing quite disturbing was a weird hearing for up to 10 days after the chemo ended. I could hear, but it felt like I was under water at times and certain sounds (like flushing the toilet or showering) were completely different and strange. That's the cisplatin effect and wears off. Today: I feel great! Of course, psychologically the tumor stays with you for years to come, but physically I am fine. I went back to work 3.5 weeks after finishing chemo.

          Good luck with your decision, if you need any kind of advice or support, could be anything than just send me a message.
          All the Best for now!
