I had the Prosigna test after a lumpectomy and node biopsy which was clear in all 3 nodes removed. The Prosigna test came back as ‘high risk’ and the Oncologist has recommended chemotherapy as a preventative against a remote recurrence or secondary cancer. My concern is the amount of treatment he is suggesting and the fact that he can’t seem to give me any information on how much the risk will be reduced by having chemotherapy. Can I ask anybody on here who had a ‘high risk’ result what chemotherapy treatment, and how many cycles it led to. In addition did you get any information on how much it reduced the future risk. I’m just worried about what is being thrown at me with very little information on how the treatment plan was created and what benefit I will get by putting myself through this. Thanks.
I didn’t have the prosigna test but oncotype instead. My score was intermediate and I was told that chemo would decrease my recurrence score by 6.5 points. That was enough for me to go ahead with it. I had four sessions of T/C chemo three weeks apart. It wasn’t fun but was doable.
Ask your oncologist to use the Predict software devised by Addenbrookes Hospital, and to discuss the results with you. It’s software they can input all of the data about type of cancer, factors, treatments, etc., and will produce statistical data and charts giving the percentage impact on survival/chance of return of each type of treatment. I was not given this information until a year into my treatment and wish it had been discussed with me much earlier so that I could have been more involved in treatment decisions. In my case, the software showed that the single biggest impact on my chance of survival was the surgeries at 60%. Chemo and radiation only improved my chances of survival by 5%, and the ten years of estrogen blockers they wanted me to take would only have improved my chances by 1%. Every case is different, and every person must make the decisions with their medical team that is right for them. This case-specific data helps those discussions enormously.
I had PROSIGNA & it came back as intermediate risk
Chemo gave me a 4% benefit so did TC x 4 cycles
I also had a node with macromets (3mm) but no LVI or ECE
Chemo was hard but “doable”
I’m finding hormone treatment rough so am glad I did chemo
Letrozole / monthly ovarian suppression is hard !
I’m going to dig deeper into the benefit at 2, 5 7 yrs as not sure I can do this for years
Best of luck
Hi. These are excellent questions to ask. Not a lot of people ask. I heard recently that of 100 people who have chemo 80 of them never needed it. Of the 20 some people died anyway but not of cancer recurrence. It really is a very small amount of people who benefit. I watched something on bbc iplayer. Perhaps you could ask for a.l secomlnd opinion or maybe just another oncologist or maybe a bcn who would be happy to answer.your questions. I too struggle to find statistics online. It was my onco - radiographer / radiologist who told me the recurrence rate (at that time, June 2017) was around 35% which horrified me. I also asked the senior radiographer at the start why I was having it. She said belt and braces approach in other words just in case I was one of the unlucky ones. Best asvice I have is to keep on aski g, everyone everywhere until you get your answers. And well done on being brave enough to want to know xx
I asked my oncologist what % benefit I would get from chemo. He said the latest predictive tool they used gave a 1-2% extra help. Keeping in mind the damage that chemo can cause I said to him that I decided to “park” the chemo and he agreed with me. I had surgery to remove er+ve lump as well as some lymph nodes. Then 15 days of radiotherapy and 5 years of oestrogen inhibitor.
Thanks for this. I did the Predict tool online and discussed it with him as for me chemo only showed a 2% benefit at 5 years and was actually worse than no chemo at 10 years. He just dismissed it and said it wasn’t relevant as it only shows breast cancer recurrence and that the Prosigna meant I was at high risk of secondary cancer which would be incurable. Just felt like I was been pushed into a decision I wasn’t sure about.
Hi Daisy , it might help to talk this through with the Breast Cancer Now nurses on the helpline ? They are good at helping you think through difficult decisions .Best wishes Jill
