The role of biological markers as predictors of response to preoperative chemotherapy in large primary breast cancer.

The aim of this prospective study was to evaluate biological markers, their correlation with response and outcome, and the change in these markers under the influence of preoperative chemotherapy (PCT) in patients with a large primary breast cancer. One hundred and thirty-five women were treated with PCT, followed by locoregional therapy and adjuvant treatment. Estrogen receptor (ER), progesterone receptor (PgR), HER-2, p53, and cathepsin D were determined by immunohistochemistry (IHC) before and after PCT.

Better cosmetic results and comparable quality of life after skin-sparing mastectomy and immediate autologous breast reconstruction compared to breast conservative treatment.

Preoperative chemotherapy (PCT) can be used in large primary breast cancer to facilitate breast conservative surgery (BCS). Cosmetic results of BCS are influenced by the size of the residual tumour, relative to the size of the breast. After mastectomy, immediate breast reconstruction (IBR) with autologous tissue provides excellent cosmetic outcome and has proven to be safe in breast cancer patients.
