The introduction of sentinel-lymph-node biopsy has brought new impetus to the early staging of cancer in general, and breast cancer in particular. This technique has rekindled the discussion on the present role and routine practice of axillary-lymph-node dissection in early breast cancer, the methods available for the histopathological assessment of lymph nodes, and the current thoughts about best surgical practice in the management of breast cancer. Sentinel-lymph-node biopsy has spread so rapidly that surgeons, pathologists, and patients are no longer willing or able to ignore the possible consequences of its implementation. A vast amount of data (over 1150 publications in the peer-reviewed literature on this subject to date) attests to the explosive interest in the past 5 years. In this article we review our own experience and discuss recommendations for clinical practice.

Early prediction of patient responses to neoadjuvant chemotherapy (NACT) is essential for the precision treatment of early breast cancer (EBC). Therefore, this study aims to noninvasively and early predict pathological complete response (pCR). We used dynamic ultrasound (US) imaging changes acquired during NACT, along with clinicopathological features, to create a nomogram and construct a machine learning model.

A clinical study in anthracycline-refractory MpBC patients suggested that nitric oxide synthase (NOS) inhibitor NG-monomethyl-l-arginine (L-NMMA) may augment anti-tumor efficacy of taxane. We report that NOS blockade potentiated response of human MpBC cell lines and tumors to phosphoinositide 3-kinase (PI3K) inhibitor alpelisib and taxane.

There have been notable shifts in practice, aiming to minimize morbidity while maintaining oncologic outcomes and accurate staging for newly diagnosed breast cancer patients. These advancements have been facilitated by the improved efficacy of adjuvant therapies.
