Risk factors for pregnancy-associated breast cancer include early age of menarche, nulliparity, personal history of breast cancer, advanced maternal age, family history of breast cancer, increased consumption INK1197 cell line of alcohol, obesity and a sedentary lifestyle [4]. Of interest to Obstetricians is the management of breast cancer in pregnancy. The timing of delivery should take into account maternal and fetal status as well as need for further chemotherapy and expected perinatal outcome while the mode of delivery should

be determined by standard obstetrical indications [5]. In an article by Trichopoulos et al., full term births over the age of 35 years had an increased risk in the development of breast cancer; uniparous women were observed to have an elevated risk of breast cancer soon after delivery, specifically those women who are 30 years or older at the time of

their first delivery [6]. We present a case of premenopausal invasive ductal carcinoma of the breast diagnosed during pregnancy, and review the literature regarding the antenatal management of breast cancer. A 29 year old multiparous Hispanic female presented to our routine obstetrical clinic at 7 weeks gestation. She had a past medical history significant for morbid obesity and poorly controlled type http://www.selleckchem.com/products/Adriamycin.html 2 diabetes mellitus with a hemoglobin A1C of 10.7. On physical exam, the patient was noted to have a left breast mass at the 11 o’clock position. Otherwise both breasts appeared symmetrical with no signs of skin changes or lymphadenopathy. Similarly, both nipples and areola had no abnormal findings. A breast ultrasound was performed and demonstrated a 4.5 × 2.6 × 3.2 cm mass that was irregular and hypoechoic consistent with BIRADS 4 classification. A core needle biopsy was performed and revealed invasive ductal carcinoma that was estrogen and progesterone receptor

positive and HER2 negative. The patient underwent a left modified radical mastectomy with left axillary lymph node dissection. Final pathology confirmed invasive ductal carcinoma of the left breast, staged at T3N2MX with ER and PR positivity in 80% and 70% of the tumor cells respectively. The patient was treated with a combination of 4 cycles of doxorubicin and Carnitine palmitoyltransferase II cyclophosphamide during the second and third trimester. At 37 weeks gestation she was diagnosed with preeclampsia and underwent delivery. A repeat cesarean section along with a risk-reducing bilateral salpingo-oophorectomy was performed. Postoperatively a chest and abdomino-pelvic computed tomography as well as a brain MRI were performed and showed no evidence of metastases. Weekly paclitaxel was started on post-operative day 7 and was continued for 3 months. The patient has also completed radiation to the chest wall and nodal areas.
