- Abstract : Background: Assessment of the oestrogen receptor (ER) provides important prognostic information in breast cancer. The impact of progesterone receptor (PgR) status is less clear. Standardization of immunohistochemical analysis of these receptors has reduced interstudy heterogeneity. The aim of this meta‐analysis was to evaluate the impact of PgR negativity on outcomes in ER‐positive (ER+) breast cancer. Methods: This study was performed according to PRISMA and MOOSE guidelines. PubMed, Embase and the Cochrane Library were searched systematically to identify studies comparing disease‐free survival as the primary outcome and overall survival as secondary outcome between PgR‐positive (PgR+) and PgR‐negative (PgR–) status in ER+ breast cancer. A meta‐analysis of time‐to‐effect measures from included studies was undertaken. Results: Eight studies including 13 667 patients, 11 838 in the ER+PgR+ group and 1829 in the ER+PgR– group, met the inclusion criteria. Treatment characteristics did not differ significantly between the two groups. Patients in the ER+PgR– group had a higher risk of disease recurrence than those who had ER+PgR+ disease (hazard ratio (HR) 1·57, 95 per cent c.i. 1·38 to 1·79; P < 0·001). This hazard was increased in patients with human epidermal growth factor receptor 2‐negative tumours (HR 1·62, 1·37 to 1·93; P < 0·001). A similar result was observed for overall survival (HR 1·69, 1·33 to 2·14; P < 0·001). Conclusion: PgR negativity is associatedAbstract : Background: Assessment of the oestrogen receptor (ER) provides important prognostic information in breast cancer.

Conclusion: PgR negativity is associated with significant reductions in disease‐free and overall survival in ER+ breast cancer. Treatment and surveillance strategies in these patients should be tailored accordingly. Abstract : In patients with oestrogen receptor‐positive tumours, progesterone receptor negativity is associated with reduced disease‐free survival. It also reduces overall survival. Indicates aggressive disease Abstract : Antecedentes: La evaluación del receptor de estrógenos ( oestrogen receptor, ER) proporciona una importante información pronóstica en el cáncer de mama. El impacto de del estado del receptor de la progesterona ( progesterone receptor, PgR) está menos claro. La estandarización del análisis inmunohistoquímico de estos receptores ha reducido la heterogeneidad entre los estudios. El objetivo de este metaanálisis fue evaluar el impacto de la negatividad de PgR (PgR‐) en los resultados del cáncer de mama ER positivo (ER+). Métodos: Este estudio se realizó de acuerdo con las directrices PRISMA/MOOSE. Se llevó a cabo una búsqueda sistemática en MEDLINE, PubMed y biblioteca Cochrane para identificar estudios que comparasen la supervivencia libre de enfermedad ( disease free survival, DFS) como resultado primario y la supervivencia global ( overall survival, OS) como resultado secundario entre los estados PgR+ y PgR‐ en el cáncer de mama ER+. Se realizó un metaanálisis de los estudios incluidos de las medidas de tiempo hasta el efecto. Resultados: Ocho estudios que incluían 13.533 pacientes, 11.724 en el grupo ER+PgR+ y 1.809 en el grupo ER+PgR‐ cumplieron con los criterios de inclusión. Las características del tratamiento no diferían significativamente entre los dos grupos. Los pacientes en el grupo ER+PgR‐ presentaron un riesgo más elevado de recidiva de la enfermedad que aquellas que tenían enfermedad ER+PgR+ (DFS, cociente de riesgos instantáneos, hazard ratio, HR 1, 57; i.c. del 95% 1, 38‐1, 79; P < 0, 001). Este riesgo se incrementó en pacientes que eran HER2 negativo (DFS HR 1, 62; i.c. del 95% 1, 37‐1, 93; P < 0, 001). Un resultado similar se observó para la OS (HR 1, 69; i.c. del 95% 1, 33‐2, 14, P < 0, 001). Conclusión: La negatividad de PgR se asocia con disminuciones significativas de DFS y OS en el cáncer de mama ER+. En estas pacientes, las estrategias de tratamiento y seguimiento en deberán adecuarse a cada caso particular. … (more)
