The study compared the outcomes of emergency IVF for cancer to IVF for tubal factor infertility. They had 22 women in each group and the outcome measures were similar between the two groups. Also, the emergency IVF did not delay the cancer treatment much if any.
Two of the cancer patents (9%) had no embryos from the IVF. My experience is similar in that I have also seen a number of cancer patient who respond poorly to IVF when they are ill from cancer. I believe that this fact should be part of the counseling process to prepare women and prevent the disappointment that follows when they are already stressed from dealing with cancer and everything that goes with it.
Nevertheless, the positive message from this study is that most women will respond to ovarian stimulation and produce eggs and embryos to preserve their fertility.
