Primary Systemic Therapy in Breast Cancer

Primary systemic therapy of breast cancer.

Primary systemic therapy (PST) or neoadjuvant therapy is used in nonmetastatic breast cancer to treat systemic disease earlier, decrease tumor bulk ideally to a complete pathological response (pCR), and reduce the extent of surgery. The multitude of clinical trials using PST in breast cancer patients has not proven the fundamental hypotheses of improved overall survival and disease-free surviva...

Option: Breast Conservation after Primary Systemic Therapy

The primary administration of chemotherapy leads to a reduction in size of tumors, increasing the possibility of breast-conserving surgery in both locally advanced, inoperable and primary operable mamma carcinomas. This, however, increases the rate of local relapse and the rate of mastectomy over the course of the disease, even although the EUSOMA guidelines are not exceeded. Whether the pre-su...

Neoadjuvant Systemic Therapy in Breast Cancer

[Neoadjuvant systemic therapy in breast cancer].

Neoadjuvant (preoperative) systemic therapy is a good possibility for the treatment of symptomatic breast cancers of the locoregional stage. Chemotherapy or hormone therapy chosen according to the characteristics of the primary tumor, result in the regression of the tumor in the majority of the cases, favoring breast conserving surgery thereafter. The long-term effects of neoadjuvant systemic t...

Primary systemic therapy and whole breast irradiation for locally advanced breast cancer: a systematic review.

The current management of locally advanced breast cancer (LABC) is based on tri-modality treatment including chemotherapy, radiotherapy and surgery. The concept of preoperative concurrent or sequential chemoradiation for LABC was initially reported more than a decade ago; however this concept did not gain popularity because of the low benefit/risk ratio and the lack of strong data supporting th...
