[Desire for children in tumor patients].
After a chemo- and/or radiotherapy not only acute side effects but also longterm side effects do occur. The following longterm side effects are observed: irregularities in the menstrual cycle, early onset of menopause and infertility. They are of special importance to children, teenagers and young adults having survived a malignancy. For young women experiencing a premature menopause a hormone replacement therapy is indicated. The degree of gonadal failure depends on the total dose of cytotoxics, radiation or the combination of both. Alkylating substances are responsible for gonadal failure whereas other cytotoxic agents lead to reversible gonadal dysfunction. An important risk factor for the development of ovarian failure is the woman's age at the time of treatment. A pregnancy in patients with a history of malignancy always is a high risk pregnancy and needs a close follow up. The offspring of cancer survivors do not show a higher rate of chromosomal abnormalities or neoplasms. Before starting a chemo- and/or radiotherapy the patient should be informed about acute and late effects. Men and adolescent boys should be given the opportunity for sperm cryopreservation. It is unclear whether a fertility reserve can be achieved by cryopreservation also in women.
