In September 2020 I was diagnosed with Stage III peritoneal high-grade serous ovarian cancer and since then I had chemotherapy followed by bebulking surgery, then more chemo and 18 sessions of maintenance treatment with Avastin. Whilst having my last 2 sessions of Avastin, my CA125, previously lowered to 10 with the chemo, increased to 100 and in my latest blood test, on 10th January, increased to 200. The CT scan I had on the same day showed that a mild version of the same cancer came back.

My oncologist thinks it is better to try to make it stable by my taking Tamoxifen rather than to have chemo.

I have two questions to ask and I phoned the hospital but I could not manage to talk with an oncologist.  My next consultation is on 17th March, which is a long time to wait. I wonder if you could help me.

Questions:

Why not bring down the CA125 to 30 first and then immediately be on Tamoxifen? 

What are the risks of the cancer affecting other organs such as liver, stomach and lungs although stabilized by Tamoxifen?

My thanks in advance for your help

  • Hi Vania,

    Thanks very much for getting in touch and welcome to our online community, I hope you find it supportive.

    I’m sorry to read that your CA125 has started to increase. It’s completely understandable to have questions about which treatment is best for you, especially as your levels lowered with chemotherapy.

    Usually if an ovarian cancer comes back it is treated with chemotherapy, targeted therapies and sometimes surgery.

    I’m wondering if the chemotherapy you had was a platinum based one. You may have heard of ‘carboplatin’ which is a platinum-based drug and can be given either on its own or with another chemotherapy called ‘paclitaxel’. This is a common regime for first line treatment for ovarian cancer.

    After having these types of drugs and a cancer comes back, the doctors either call it a ‘platinum sensitive’ cancer or ‘platinum resistant’ cancer. This link explains other treatments that might be offered including hormone and targeted therapy in this situation.

    It’s so difficult for the nurses on this platform to advise on specific treatments in individual situations, as we are separate from the NHS and don’t have access to medical records. I appreciate you have tried to get in touch with your hospital team and finding it difficult to speak with your oncologist.

    If you have a clinical nurse specialist, I encourage you to get in contact with them, as they do have access to your medical records and can answer specific questions you have, or speak with your consultant for you.

    This will give you the opportunity to ask about your risk of the cancer affecting other organs in your body while on Tamoxifen.

    I hope this information is helpful but if you have any more questions please don’t hesitate to get back in touch.

    Take care and best wishes,

    Sarah (cancer information nurse specialist)
