Predicting the age at menopause of women having suffered from childhood cancers
Date:12/4/2012

This press release is available in French.

This study provided important data about the fertility window of women who had suffered from childhood cancer and information concerning the associated risk factors, but did not confirm the greater risk of premature menopause (before the age of 40) that was reported by the American studies.

The results were published in the review Human Reproduction of November 15.

Women who have suffered from childhood cancer are known to run a greater risk of premature menopause. However, data about the associated risk factors is limited. Researchers from unit 1018 "Centre for Research in Epidemiology and Population Health (CESP)" (Inserm/Universit Paris-Sud/Institut Gustave Roussy) and from the AP-HP analyzed the data from a French cohort, named Euro2k, concerning 1522 survivors of childhood cancer diagnosed between 1945 and 1986 when they were under 18, initially in order to study the mortality rate. The study estimated the radiation doses received at the ovaries by the women in this cohort who had been treated by radiotherapy. 706 of these women filled in a detailed questionnaire about their state of health. 32% of these women had already reached the age of 40 years; 7% were over 50 years of age. The research team studied the age at menopause of these women and the potentially associated risk factors. The researchers based this study on self-reported questionnaires sent to the women in order to obtain information about the menopause, without confirming by measuring FSH levels.

Analysis of this data showed that 97 women (13,7%) were menopaused at a median age of 44 years, in other words, 7 years earlier than the general population. For a third of these women (36%), menopause was surgically induced.

The researchers concentrated on the risk factors of menopause in these women, who had been su
