title: Neoadjuvant chemotherapy for locally advanced breast cancer: a single center experience.
abstract: Neoadjuvant chemotherapy (NAC) is one of the treatment options for patients with locally advanced breast cancer (LABC). Preoperative chemotherapy potentially may reduce the extent of the surgery and offers the opportunity to assess the chemosensitivity of the tumor in vivo. Herein, we evaluated the results of NAC in Turkish LABC patients. We retrospectively analyzed 73 LABC patients. Anthracycline/taxane-based chemotherapy regimens were administered. Patients were stratified according to age, menopausal status, type of surgery, response to the treatment, histopathological properties, and survival. After 3-6 cycles of chemotherapy, patients were re-staged radiologically and surgery was performed in operable patients. Adjuvant chemotherapy was administered as needed. The median age was 45 (29-93) at the time of diagnosis. Sixteen percentage of patients were younger than 35 years of age and 45.2% were premenopausal. Median follow-up time was 20.2 months. Sixty-seven out of 73 patients responded to therapy (89%). Breast conserving surgery was possible in the 15% of the patients. In histopathological analysis, lymph node invasion was detected in 85%. The estrogen (ER) and progesterone (PR) receptor were positive in 78.1% and c-erb-B2 was positive in 17.5% of patients. The median disease-free survival (DFS) was 44 months (SE: 9; %95 CI: 27.1-60.8), overall survival (OS) was not reached at the time of analysis. Three-year DFS and OS were 58% and 91.9%, respectively. In a multivariate Cox regression analyses; no demographic or pathologic prognostic parameter predicted overall survival. In recent years, NAC in breast cancer has become a viable treatment option for patients with LABC. NAC is not commonly applied in Turkey. The response rate to NAC in Turkish breast cancer patients is encouragingly high. Broader efforts should be made to evaluate breast cancer patients preoperatively at tumor boards for proper treatment sequence.
