- Abstract : Background: Young age at breast cancer diagnosis is associated with negative prognostic outcomes, and breast cancer in black women often manifests at a young age. This study evaluated the effect of age on breast cancer management and outcomes in black women. Methods: This was a retrospective cohort study of all black women treated for invasive breast cancer between 2005 and 2010 at a specialized tertiary‐care cancer centre. Clinical and treatment characteristics were compared by age. Kaplan–Meier methodology was used to estimate overall survival (OS) and disease‐free survival (DFS). Results: A total of 666 black women were identified. Median BMI was 30 (range 17–56) kg/m 2 and median tumour size was 16 (1–155) mm. Most tumours were oestrogen receptor‐positive (66·4 per cent). Women were stratified by age: less than 40 years (74, 11·1 per cent) versus 40 years or more (592, 88·9 per cent). Younger women were significantly more likely to have a mastectomy, axillary lymph node dissection and to receive chemotherapy, and were more likely to have lymphovascular invasion and positive lymph nodes, than older women. The 5‐year OS rate was 88·0 (95 per cent c.i. 86·0 to 91·0) per cent and the 5‐year DFS rate was 82·0 (79·0 to 85·0) per cent. There was no statistically significant difference in OS by age ( P = 0·236). Although DFS was inferior in younger women on univariable analysis (71 versus 88 per cent; P < 0·001), no association was found with age on multivariableAbstract : Background: Young age at breast cancer diagnosis is associated with negative prognostic outcomes, and breast cancer in black women often manifests at a young age.

Although DFS was inferior in younger women on univariable analysis (71 versus 88 per cent; P < 0·001), no association was found with age on multivariable analysis. Conclusion: Young black women with breast cancer had more adverse pathological factors, received more aggressive treatment, and had worse DFS on univariable analysis. Young age at diagnosis was, however, not an independent predictor of outcome. Abstract : This study evaluated the impact of age on outcomes in US black women with invasive breast cancer. Although younger black women with breast cancer had more adverse pathological factors, age was not significantly associated with outcome. Worse prognosis Abstract : Antecedentes: El diagnóstico de cáncer de mama a una edad joven se asocia con un pronóstico de resultados negativo, y en mujeres de raza negra, el cáncer de mama con frecuencia se manifiesta a edades tempranas. Este estudio analiza el efecto de la edad en el tratamiento y resultados del cáncer de mama en mujeres de raza negra. Métodos: Estudio de cohortes retrospectivo de todas las mujeres de raza negra tratadas por cáncer de mama invasivo entre 2005‐2010 en un centro oncológico terciario de alta especialización. Se compararon las características clínicas y del tratamiento en función de la edad. Se estimó la supervivencia global ( overall survival, OS) y la supervivencia libre de enfermedad ( disease‐free survival, DFS) con el método de Kaplan‐Meier y se utilizó la prueba de log‐rank para las comparaciones entre grupos. Resultados: Se identificaron un total de 666 mujeres de raza negra. La mediana del tamaño del tumor fue de 16 mm (rango 1‐155 mm). La mayoría de los tumores fueron positivos para el receptor de estrógenos (66, 4%); la mediana del índice de masa corporal (IMC) fue 30 kg/m 2 (rango 17, 2‐56, 5). Se estratificaron a las mujeres por su edad: < 40 años ( n = 74; 11, 1%) frente a ≥ 40 años ( n = 592; 88, 9%). La probabilidad de recibir una mastectomía, un vaciamiento ganglionar axilar y quimioterapia fue significativamente superior en las pacientes jóvenes y además fueron más propensas a presentar invasión linfovascular y ganglios linfáticos positivos en comparación con las mujeres mayores. Las OS y DFS a los 5 años fueron del 88, 0% (i.c. del 95% 86‐91%) y del 82% (i.c. del 95% 79‐85%), respectivamente. No se observaron diferencias estadísticamente significativas en la OS ( P = 0, 236) en función de la edad. Aunque en el análisis univariado la DFS fue peor en las mujeres jóvenes (71% versus 88%, log‐rank P < 0, 001), en el análisis multivariable no se confirmó la asociación con la edad. Conclusión: Las mujeres jóvenes de raza negra con cáncer de mama tuvieron más factores patológicos adversos, recibieron un tratamiento más agresivo y tuvieron una DFS peor en el análisis univariado. Sin embargo, la edad temprana en el momento del diagnóstico no fue un factor predictivo independiente del resultado. … (more)
