RESUMEN
INTRODUCTION: Breast cancer is a worldwide public health problem. In Colombia, there are 13,000 new cases, having the highest incidence and mortality among cancers. This article describes the clinical behavior of patients with triple negative breast cancer (TNBC) treated at the National Cancer Institute (NCI) in Bogota, Colombia. METHODS: A historical cohort and analytical study that included elderly patients diagnosed with TNBC treated at the National Cancer Institute Functional Breast Cancer Unit (NCI-FBCU) was conducted. RESULTS: Of the 1,066 patients registered in the unit from September 1st 2013 to December 31st 2016: 146 (13.7 %) had triple negative tumors. The average age was 57.3 years; 61% of patients had locally advanced tumors. The majority of patients received neoadjuvant chemotherapy as their first treatment (69.1%), and in 41.2% of the cases platinum was added to the chemotherapy regimen. The most common surgery conducted was modified radical mastectomy in 57.8% of cases. The pathological complete response (pCR) (Chevallier 1 and 2) was reached in 22.6% and, in this group of patients, a greater overall survival (OS) was found [hazard ratio (HR) 0.08, 95% CI 0.01-0.63; p = 0.016]. Progression of the disease occurred in 36.5% of cases, being lungs the most frequent location (44.4%). The death incidence rate was 1.21 deaths per 100 patients/month. The median event-free survival (EFS) was 18.2 months. CONCLUSION: TNBC occurs in Latin American women at advanced clinical stages with aggressive clinical behavior, with lower OS rates, and higher risk of metastasis compared to other molecular subtypes.
RESUMEN
ABSTRACT Objective: To identify differences in quality of life and sexuality in women without genital prolapse taken to vaginal or abdominal hysterectomy. Materials and methods: Prospective cohort study including women with no vaginal prolapse and benign conditions, with no adhesions and a uterus of less than 1000cc, amenable to surgery through the abdominal or vaginal approach, coming to a private clinic in Medellín, Colombia. The SF12 score was used for quality of life assessment two and four months after surgery, and sexuality was assessed before and four months after the procedure, using the Female Sexual Function Index. Comparisons were made using ANCOVA, adjusted on the basis of baseline values and other characteristics. Approval by the ethics committee as well as informed consents were obtained. Results: The study included women with similar pre-operative characteristics. Of them, 24 were included in the vaginal hysterectomy group and 22 in the abdominal hysterectomy group. Quality of life and sexual function improved for the women in both groups following the procedure. Postoperative physical health: adjusted score for vaginal hysterectomy, 49.5 (SD ± 1.6) and for abdominal hysterectomy, 43.8 (SD ± 1.7), with a difference of 5.6 points (95% CI 0.87-10.4). Mental health: 51.0 (SD ± 1.7) and 59.3 (SD ± 1.6) points, respectively; adjusted difference 8.4 (95% CI 3.6-13.3). Sexuality: 22.7 (SD ± 1.8) and 26.5 (SD ± 1.7), respectively; difference, 3.8 points (95% CI -1.2-8.7). Conclusion: Although statistically significant differences were found for quality of life, the score obtained is not clinically significant.
RESUMEN Objetivo: Identificar diferencias en calidad de vida y sexualidad en mujeres sin prolapso genital intervenidas con histerectomía vaginal o abdominal. Materiales y métodos: Estudio de cohortes prospectivo. Se incluyeron mujeres sin prolapso vaginal con condiciones benignas, sin adherencias, con útero menor de 1000 cc, que fueran susceptibles de ser intervenidas tanto por vía abdominal como vaginal en una clínica privada de Medellín, Colombia. Evaluación de calidad de vida con la escala SF-12 antes, a los 2 y 4 meses posquirúrgico y de la sexualidad con la escala índice de Función Sexual Femenina, antes y a los 4 meses posoperatorio. Comparaciones con ANCOVA ajustadas porlos valores basales y por otras características. Se contó con aprobación de comité de ética y se tomó consentimiento informado. Resultados: Se incluyeron 24 mujeres en el grupo de histerectomía vaginal y 22 en el grupo de histerectomía abdominal, con características similares antes de la cirugía. Ambos grupos mejoraron en calidad de vida y en satisfacción sexual después del proce- dimiento. Los puntajes para histerectomía vaginal e histerectomía abdominal fueron, respectivamente: salud física posoperatoria: puntaje ajustado en histerectomía vaginal 49,5 (DE ± 1,6) e histerectomía abdominal 43,8 (DE ± 6,7), diferencia 5,6 puntos (IC 95%: 0,87-10,4). Salud mental: 51,0 (DE ± 1,7) y 59,3 (DE ± 1,6) puntos, respectivamente, diferencia ajustada 8,4 (IC 95%: 3,6-13,3). Sexualidad: 22,7 (DE ± 1,8) y 26,5 (DE ± 1,7), respectivamente, diferencia 3,8 puntos (IC 95%: -1,2-8,7). Conclusión: Aunque se encontraron diferencias estadísticamente significativas en la calidad de vida, el puntaje alcanzado no es clínicamente significativo.
