Pregnancy is possible after cancer treatmentApril 24, 2008It has been reported for the first time in Germany that healthy ovarian tissue has been taken from a non-pregnant woman with cancer and then re-implanted after cancer therapy. The patient is now 32 years old and could become pregnant as a result. This case is described by Ralf Dittrich and his colleagues from Erlangen University Hospital in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2008; 105[15]: 274-8). Anal carcinoma was diagnosed in this young patient in 2004 and chemotherapy followed by radiotherapy was recommended. As the ovaries lie near to the tumor, they are often damaged by therapy of this sort and the women become infertile. The Erlangen physicians succeeded in removing healthy ovarian tissue from the woman before treatment and to freeze it. The patient was then given the recommended cancer treatment. She tolerated this well and has not suffered any relapse. On the other hand, her menstrual periods had stopped, in spite of hormone treatment, for two years. For this reason, the patient's conserved ovarian material was inserted endoscopically into her pelvis. She subsequently reported her first menstruation. After this operation, it may be possible for her to become pregnant, although this has not happened yet. The authors consider that the affected patients should be provided with more information, so that they are aware of this possibility of retaining fertility.

Related Ovarian Tissue News Articles New ovarian stimulation technique offers more cancer patients the chance to preserve their fertility Researchers have shown for the first time that it is possible to stimulate a woman's ovaries to produce eggs for collection during the final phase of the menstrual cycle. Cancer could return unless stored ovarian tissue undergoes adequate testing before re-implantation Cancer patients who have been successfully treated for their disease face the prospect of its return if stored ovarian (or testicular) tissue is transplanted back into their bodies without adequate checks, according to researchers at two university hospitals in Israel. OHSU is part of national effort to preserve, restore fertility in women with cancer The Oregon National Primate Research Center and the Oregon Health & Science University School of Medicine have been named to a national team of institutions hoping to preserve or restore fertility in women battling cancer. First case of successful ovarian tissue transplantation between two, nonidentical sisters A woman, whose ovaries had failed due to damage caused by chemotherapy and radiotherapy, has received a successful ovarian transplant from her genetically non-identical sister. New genetic marker characterizes aggressiveness of cancer cells Levels of a small non-coding RNA molecule called let-7 appear to define different stages of cancer better than some of the "classical" markers for tumor progression. Studies to find better ways to preserve human eggs, ovarian tissue under way The goal is to make human eggs, ovarian tissue, blood vessels, even whole organs available when needed. Researchers identify ovarian cancer biomarkers Researchers have identified markers unique to the cells of blood vessels running through ovarian tumors. The finding, while preliminary, could one day improve screening, diagnosis and treatment for this disease.

Ovarian Cancer May Mimic Fallopian Tube Formation A new study suggests that ovarian cancer cells form by hijacking a developmental genetic process normally used to form fallopian tubes. Scientists at the Georgia Institute of Technology and the Ovarian Cancer Institute discovered that the protein, PAX8, is involved in the development of fallopian tubes and is present in ovarian cancer cells, but not in normal ovarian tissue. Program to freeze women's ovaries to preserve fertility after cancer The Center for Reproductive Research at Northwestern University is launching a new, experimental research program for young women who may be at risk to lose their ovarian function and fertility following treatment for cancer.
