Pregnancy-Associated Breast Cancer: A Realistic Approach
- 5 Downloads
The number of cancers diagnosed during pregnancy is on the rise, and breast cancer is the most common malignancy. Presently, there are very limited resources and no clear guidelines for managing this peculiar patient population both worldwide and in India. The objective of this study was to find out the incidence of pregnancy-associated breast cancer (PABC) in a tertiary care referral centre and to compare the epidemiological, diagnostic and prognostic factors as well as maternal and foetal outcomes with the most recent literature worldwide.
We conducted a retrospective descriptive study of women diagnosed with breast cancer in pregnancy and post-partum period at a tertiary care centre in southern India during the period of 10 years (total number of breast cancer patients were 10). We studied the diagnostic and prognostic factors as well as maternal and foetal outcome in patients diagnosed with breast cancer for the first time in pregnancy.
Overall incidence of PABC was found to be 0.6% (n = 10). Mean age at the time of presentation was 30.7 ± 4 years. All cases suspected clinically or on imaging (USG) were confirmed with FNAC, excision biopsy or Trucut biopsy. Out of 10 patients, 70% (n = 7) had an advanced-stage disease on diagnosis. Histopathology suggested 90% (n = 9) had invasive ductal carcinoma and 55.5% (n = 5) had a triple negative receptor status. 20% (n = 2) of our patients had opted for a breast conservation surgery (BCS), and 70% (n = 7) of our patients underwent modified radical mastectomy with neoadjuvant or adjuvant chemotherapy/radiotherapy. One patient had a second trimester MTP in view of stage 4 disease. 77.7% (n = 7) of the nine patients who continued pregnancy underwent LSCS, out of which 57.4% (n = 4) were elective, and MRM was done concurrently with LSCS in 50% (n = 2) of the elective LSCS. The mean birth weight of the 9 neonates was 2.2 ± 0.5 kg. Intrauterine growth retardation was seen in 22.2% (n = 2) neonates. 33.3% (n = 3) of the neonates required NICU support, and one baby expired on post-natal day 16.
With the increasing number of elderly primigravida amongst the urban population, a clear understanding of PABC is becoming more important. A multidisciplinary team approach shall help the clinician not only in reducing the heavy burden of patient responsibility but more importantly, in guaranteeing better quality of treatment, avoiding unnecessary delays in providing interventions and providing adequate treatment.
