Recomendación para la determinación de HER2 en cáncer de mama. Consenso nacional de la Sociedad Española de Anatomía Patológica (SEAP) y de la Socied…

2009

La identificación de los carcinomas de mama con amplificación/sobreexpresión de HER2 es crítica en la práctica clínica diaria ya que estas neoplasias requieren un tratamiento específico que incluye el uso de terapias dirigidas. Tanto las técnicas de hibridación in situ como las técnicas inmunohistoquímicas son métodos apropiados para la identificación de cánceres de mama HER2 positivos. Sin embargo, numerosos estudios, incluidos los desarrollados por la Asociación para la Garantía de Calidad en Patología de la SEAP (AGCP) y la experiencia de centros de referencia nacionales en la determinación de HER2 han puesto de manifiesto importantes problemas de reproducibilidad entre laboratorios. Por…

Targeted Therapy Modulates the Secretome of Cancer-Associated Fibroblasts to Induce Resistance in HER2-Positive Breast Cancer

2021

The combination of trastuzumab plus pertuzumab plus docetaxel as a first-line therapy in patients with HER2-positive metastatic breast cancer has provided significant clinical benefits compared to trastuzumab plus docetaxel alone. However, despite the therapeutic success of existing therapies targeting HER2, tumours invariably relapse. Therefore, there is an urgent need to improve our understanding of the mechanisms governing resistance, so that specific therapeutic strategies can be developed to provide improved efficacy. It is well known that the tumour microenvironment (TME) has a significant impact on cancer behaviour. Cancer-associated fibroblasts (CAFs) are essential components of the…

HER2 Signaling and Breast Cancer Stem Cells: The Bridge behind HER2-Positive Breast Cancer Aggressiveness and Therapy Refractoriness

2021

Simple Summary Breast cancer (BC) is not a single disease, but a group of different tumors, and altered HER2 expression defines a particularly aggressive subtype. Although HER2 pharmacological inhibition has dramatically improved the prognosis of HER2-positive BC patients, there is still an urgent need for improved knowledge of HER2 biology and mechanisms underlying HER2-driven aggressiveness and drug susceptibility. Emerging data suggest that the clinical efficacy of molecularly targeted therapies is related to their ability to target breast cancer stem cells (BCSCs), a population that is not only self-sustaining and able to differentiate into distinct lineages, but also contributes to tum…

Monoclonal antibodies for the treatment of non-haematological tumours: update of an expanding scenario.

2015

Abstract: Introduction: The identification of cell membrane-bound molecules with a relevant role in cancer cell survival prompted the development of moAbs to block the related pathways. In the last few years, the number of approved moAbs for cancer treatment has constantly increased. Many of these drugs significantly improved the survival outcomes in patients with solid tumours. Areas covered: In this review, all the FDA-approved moAbs in solid tumours have been described. This is an update of moAbs available for cancer treatment nowadays in comparison with the moAbs approved until few years ago. The moAbs under development are also discussed here. Expert opinion: The research on cancer ant…

Nuevas vías moleculares implicadas en los mecanismos de resistencia primaria y adquirida en cáncer de mama HER2 positivo

2018

El cáncer de mama es el tumor más frecuente en la mujer, representa aproximadamente el 28% de todas las neoplasias y es la principal causa de muerte por cáncer en las mujeres europeas. A pesar de los avances en el tratamiento y en el diagnóstico temprano, sigue siendo un importante problema de salud pública. El 20% de las pacientes diagnosticadas de cáncer de mama presentan una recaída. La enfermedad en estadios avanzados sigue siendo incurable con una supervivencia media de 2-3 años y una supervivencia global de 25% a los 5 años. El cáncer de mama es una enfermedad heterogénea que podemos clasificar en: luminal A, luminal B, HER2 amplificado o triple negativo en función de criterios anatom…
