PURPOSE: To determine the frequency of return of ovarian function after
autologous bone marrow transplantation (ABMT), and the major factors that
predict recovery. PATIENTS AND METHODS: Records of 200 consecutive women
who underwent ABMT at the University of Toronto Autologous Blood and Marrow
Program (Toronto, Canada) were reviewed. Seventeen patients met the
inclusion criteria, which were (1) alive at the time of evaluation, (2)
disease-free at least 18 months after transplantation, (3) age younger than
50 years at transplantation, and (4) premenopausal before transplantation.
Recovery of ovarian function was determined by pregnancy or regular menses,
with no menopausal symptoms and an estradiol level greater than 20 pmol/L
off hormonal therapy. RESULTS: All 17 patients became menopausal
immediately after ABMT. Five patients (29%) recovered ovarian function a
median of 24 months post-ABMT (range, 6 to 48 months). The median age at
transplantation of women with restored ovarian function was 19 years
(range, 19 to 28 years) versus 30 years (range, 22 to 48 years) for those
who did not regain function. Younger age at transplantation predicted
ovarian recovery (P = .03) by means of a log-rank test. Only one of five
women who regained ovarian function received total-body irradiation (TBI)
compared with five of 12 women who did not. Univariate analysis suggested a
trend for TBI to predict a sustained loss of ovarian function (P = .067).
The number of regimens of induction or salvage chemotherapy that contained
an alkylating agent ranged from none to five and was not predictive (P =
.45). CONCLUSION: All women became menopausal after ABMT but 29% recovered
ovarian function. Younger age at transplantation predicted return of
ovarian function, whereas TBI may have had a negative effect.
