Researchers from Spain followed outcomes among 121 women aged 35 years or younger when breast cancer was diagnosed, and followed their outcomes over a period that, for some patients, exceeded 6 years. The average follow-up was 4 years. “What [we] found was that women who became pregnant after their diagnosis and treatment for breast cancer did not have outcomes that were any worse than [that of] women the same age who did not become pregnant,” said Octavi Cordoba Cardona, MD, Hospital Universitari Vall d’Hebron, Barcelona, Spain, during a poster presentation here today. “I really don’t have any explanation for this.” Of the women who were followed, 20 became pregnant. He said 8 women interrupted the pregnancy because they were taking tamoxifen. The other 12 women allowed their pregnancy to continue, and all had full-term, normal-birth babies. No miscarriages were observed. “A significant proportion of patients diagnosed with breast cancer at young age get pregnant,” said Dr. Cordoba. After 5 years, 95% of the women who became pregnant achieved disease-free survival compared with 62% of the women who did not get pregnant (P < .01). In addition, 100% of the women who became pregnant survived for at least 5 years, compared with 835 of the women who did not become pregnant (P < .01). The median age at diagnosis was 31 years in the entire cohort, and 83.2% of the women who did not get pregnant and 81% of the women who did get pregnant were diagnosed with invasive ductal carcinoma. About 51% of the nonpregnant women and 44% of the pregnant women had positive axillary nodes. About 89% of the women who did not get pregnant were treated with adjuvant chemotherapy compared with 80% of the women who did get pregnant. About 685 of women who did not get pregnant underwent hormonal therapy compared with 35% of those who did get pregnant (P = .01).
