Marriage and fertility in long-term survivors of high grade osteosarcoma.

One hundred fifteen patients with high grade osteosarcoma were treated at our hospital between 1976 and 1995. Of these, 45 patients still surviving and disease free for more than 5 years since the conclusion of treatment were enrolled as the subjects. The marriage proportion (number of married persons/number of all persons) and fertility proportion (number of persons having an offspring/number of married persons) of these 45 patients were investigated. The marriage proportion of male patients was 20.8% (5/24), whereas that of female patients was 76.2% (16/21). The marriage proportion in male patients was dramatically lower than that in female patients (p = 0.0003). The marriage proportion in male patients was significantly lower than that in brothers of the patients (p = 0.0223). In female patients, the treatment of osteosarcoma had no influence on marriage, whereas in male patients it had a great influence on marriage. The fertility proportion in married patients was 76.2% (16/21) and that in siblings of the patients was 81.0% (17/21). A total of 18 offspring were born to married patients. These offspring had no birth defects or congenital anomalies. The chemotherapy used in the treatment of osteosarcoma had little influence on the fertility of patients or the health of their offspring.
