Abstract

Herein, we report a case of synchronous bilateral triple negative invasive ductal breast carcinoma in a patient with discrepant pathologic response to neoadjuvant chemotherapy. Right and left breast cancer stages at the initial diagnosis were T1cN0M0 and T4dN3aM0, respectively. The patient was identified as a BRCA1 mutation carrier and treated with four cycles of adriamycin and cyclophosphamide, followed by four cycles of docetaxel. Bilateral breast cancer stages decreased with the first regimen. However, the bilateral breast cancers showed discrepant responses to chemotherapy with docetaxel. The right breast cancer showed a continuous tumor volume reduction while the left breast cancer showed marked progression. Finally, the tumor size was 0.3 cm and 12 cm in the right and left mastectomy specimens, respectively. As bilateral breast cancers of the same subtype may show discrepant responses to neoadjuvant chemotherapy, close monitoring and follow-up imaging are required to avoid delayed surgery.

저자들은 BRCA 유전자 변형 환자의 양측 삼중음성 유방암의 선행화학요법에 대한 상이한 반응에 대한 증례를 보고한다. 우측은 T1cN0M0, 좌측은 T4dN3aM0으로 각각 진단되었다. 환자는 Adriamycin, cyclophosphamide 항암요법 4차, docetaxel 4차를 시행 받았다. 양측 유방암은 첫 번째 항암요법 4차 이후에 부분 관해를 보였다. Docetaxel 항암요법 중 양측 유방암은 상이한 반응을 보였다. 우측 유방암은 지속적인 관해를 보였으나, 좌측 유방암은 진행되는 양상을 보였다. 전절제술 결과, 우측 유방암은 0.3 cm, 좌측은 12 cm로 측정되었다. 동일한 삼중음성 유방암에서도 항암요법에 대하여 좌우가 상이한 반응을 보일 수 있으므로, 면밀한 추적 관찰이 고려되어야 할 것이다.
