Study provides important data about fertility window of women with childhood cancer

The results showed that women who had suffered from a childhood cancer were more likely to suffer from early menopause, but did not conform the high risk of premature menopause (in other words, before 40 years of age), such as was reported in the American studies. This is probably due to the difference between the populations studied (there were no cases of leukemia or lymphoma in the Euro2k cohort population).

"In this cohort , very few women had received high doses of radiotherapy in order to receive bone marrow transplants, and only 21% of them (i.e. twice the occurrence of the general population) suffered premature menopause before the age of 40, explained C-cile Teinturier, the principal writer of the study. The main risk factors associated to these cases of premature menopause are: the older the women is when being treated for cancer, the dose of alkyating agents such as Cyclophosphamide or Melphalan received during bone marrow transplants, and the radiation dose received at the ovaries.

"This study provided information about the risk factors affecting the fertility window of women who have suffered from childhood cancer. This new data should help both to inform patients who are at risk of premature menopause, by advising them not to delay their first pregnancy until after the age of thirty, and to reassure women who present a low risk" concluded C-cile Teinturier.

It is planned to extend Cohort Euro2k to cover all patients treated for solid cancers who were under 18 years of age before the year 2000 inFrance. The aim is to study the impact of high-dose chemotherapy on the occurrence of premature menopause.
