Novel approaches to target HER2-positive breast cancer: trastuzumab emtansine.

The human epidermal growth factor receptor 2 (HER2) is overexpressed in 20% of breast carcinomas. Prior to the development of targeted therapies, HER2-positive breast cancer was associated with more aggressive disease and poor prognosis. Trastuzumab emtansine (T-DM1) is an antibody-drug conjugate that results from the combination of trastuzumab and DM1, a derivative of the antimicrotubule agent maytansine.

Anti-Hormonal Therapies for Premenopausal Patients--What did we Learn from the TEXT/SOFT Trials?

Between 20-25% of all breast cancers are diagnosed in patients younger than 50 years of age, most of whom are still premenopausal. Currently, tamoxifen is considered the standard of care for adjuvant treatment in these cases. However, in postmenopausal women, aromatase inhibitors (AIs) are a better choice.

Role of Anti-HER-2 Therapies in the Neo-Adjuvant Setting: Is Complete Pathological Response a Solid Surrogate?

Breast cancer continues to be a major health problem. Both patients and clinicians demand faster access to drugs that could result in better outcomes. In part motivated by this necessity, there has been a change in the dominant paradigm regarding how drugs become approved.

Therapeutic options for HER-2 positive breast cancer: Perspectives and future directions.

During the last 15 years we have witnessed an unprecedented expansion in the drugs developed to target human epidermal growth factor receptor-2 (HER-2) positive breast cancer. Trastuzumab, pertuzumab, ado-trastuzumab emtansine and lapatinib are currently food and drug administration (FDA)-approved for the treatment of breast cancer patients with HER-2 over-expressed. However, given the amount of information gathered from years of uninterrupted clinical research, it is essential to have periodic updates that succinctly recapitulate what we have learnt over these last years and help us to apply that information in our daily practice.

Advances and new perspectives in the treatment of metastatic colon cancer.

During the last decade we have witnessed an unprecedented outburst of new treatment approaches for the management of metastatic colon cancer. Anti-angiogenic drugs, epidermal growth factor receptor blockers and multi-kinase inhibitors have all resulted in small but consistent improvement in clinical outcomes. However, this progress has paradoxically leaded us into new challenges.
