“…This finding is consistent with another study on pregnant women with HD (Smith et al, 2001) which identified 172 cases of HD diagnosed from 9 months preceding delivery until 12 months after delivery and found relative risks of 2.4 (95% CI: 1.6 -3.5) for prematurity and 3.6 (95% CI: 1.5 -8.9) for very low birth weight. The authors suggested that these findings reflected a higher rate of elective early deliveries to allow initiation of therapy.…”

In a Danish nationwide cohort study of 292 births from 1973 to 2002 in women with Hodgkin's disease (HD), we compared birth outcome with 14 042 births from a cohort of mothers without cancer. We found no substantially increased risk of preterm birth, low birth weight at term, or stillbirth and no difference in proportion of male newborns for 192 children of women with HD before pregnancy. The prevalence odds ratio (POR) for congenital abnormalities was 1.7 (95% confidence interval (CI): 0.9 -3.1). Among 15 newborns of mothers diagnosed during pregnancy, the POR of preterm birth was 26.6 (95% CI: 8.5 -83.0), but five out of the eight preterm deliveries among these women were elective. We found no substantially increased risk of adverse birth outcome among 85 newborns of women diagnosed within 2 years postpartum, though effect estimates were imprecise. The overall findings are reassuring, they cannot exclude the possibility of an increased risk of congenital abnormalities for newborns of women diagnosed with HD before pregnancy.

“…Our finding of an increased risk of giving birth preterm for women who were diagnosed with breast cancer during or shortly after pregnancy corroborates the results of two earlier studies (Zemlickis et al, 1992;Smith et al, 2001). In a hospitalbased study, Smith et al (2001) identified 423 cases of breast cancer diagnosed from 9 months preceding delivery until 12 months after delivery over a period of 6 years in California.…”

“…Cohorts without control groups including between four and 121 women (Ribeiro et al, 1986;Daly and Donnellan, 1992;Berry et al, 1999;Giacalone et al, 1999;Kuerer et al, 2002;Ring et al, 2005) have shown that the majority of women who are diagnosed with breast cancer during or shortly after pregnancy give birth to healthy children. Two controlled studies, however, suggested an increased risk of preterm birth and low birth weight for offspring of these women (Zemlickis et al, 1992;Smith et al, 2001). Therefore, within a cohort study, we examined birth outcome in all women diagnosed with breast cancer in Denmark from 1943 to 2002, compared with women without cancer.…”

Birth outcome in women with breast cancer

et al. 2005

We investigated whether maternal breast cancer affects birth outcome in a nationwide cohort study of 695 births from 1973 to 2002 of women with breast cancer with respect to preterm birth, low birth weight at term, stillbirth and congenital abnormalities as well as mean birth weight, compared with the outcomes of 33 443 births from unaffected mothers. There was no excess risk of adverse birth outcome for the 216 newborns of women with breast cancer before pregnancy. Stratification by mother's treatment did not change the results. For 37 newborns of women diagnosed during pregnancy, the prevalence ratio (PR) of preterm birth was 8.1 (95% confidence interval (CI): 3.8 -17). However, 10 of the 12 preterm deliveries among these women were elective early deliveries. Among 442 births of women diagnosed in the 2 years from time of delivery, the PR of preterm birth was 1.4 (95% CI: 1.0 -2.0), and the PR of low birth weight at term for boys was 2.9 (95% CI: 1.3 -6.3). Overall, our results are reassuring regarding the risks of adverse birth outcome for breast cancer patients.

“…[3][4][5] Cervical neoplasia (including carcinoma in situ and invasive carcinoma) is estimated to complicate 1.5 to 12 of every 100,000 pregnancies. [6][7][8] To establish protocols for cervical cancer screening and the treatment of cervical intraepithelial neoplasia in pregnancy, we reviewed recently published guidelines [9][10][11][12] and prepared an algorithm specific to the management of CIN in pregnancy. The evaluation and management of invasive cervical cancer in pregnancy will be discussed in a separate article.…”

Cervical cancer screening is an essential component of prenatal care. The diagnosis and management of cervical intraepithelial neoplasia (CIN) during pregnancy are challenging, and sufficient information does not exist to allow for a definitive evidence-based approach. The American Society for Colposcopy and Cervical Pathology has recently published guidelines regarding the evaluation of abnormal Papanicolaou tests and the treatment of CIN in this setting. Many techniques traditionally recommended in the evaluation of abnormal cervical cytology and the treatment of CIN in the nonpregnant woman, such as colposcopy, cervical biopsy, and electrosurgical excision, can be applied to the pregnant patient with important exceptions. The vascular cervix associated with the gravid condition and the risk of premature pregnancy loss mandates deviation from existing consensus guidelines in screening for cervical cancer in pregnancy and treating associated CIN. In the present review, current guidelines regarding cervical cancer screening are reviewed, and data from studies of pregnant populations are summarized.
