Abstract: Objetivo: Determinar la sobrevida a 5 años de pacientes con cáncer de mama según grupo molecular en el Hospital Regional José Cayetano Heredia de Piura, durante el periodo 2015 - 2017.
Metodología: Fue una investigación observacional, analítica y de cohorte retrospectiva, donde se consideró una muestra de 263 mujeres con cáncer de mama seleccionadas por un muestreo probabilístico aleatorio simple. La información se extrajo de historias clínicas y el instrumento fue una ficha de recolección conformada por datos demográficos, clínicos, sobrevida y grupo molecular. El análisis estadístico se realizó mediante la regresión de Cox.
Resultados: La supervivencia global a cinco años fue 74.5%. De todos los pacientes que sobrevivieron al final del seguimiento, la mayoría fue subtipo luminal A (39.3%) y luminal B (32.1%); seguidamente, se encontraron los subtipos triples negativo (20.4%) y HER2 positivo (8.2%). En la curva de supervivencia se evidencio que la sobrevida en el grupo molecular Luminal A fue de 79.4% a 5 años, seguido por el grupo HER2 con una sobrevida 76.2% a 5 años, Luminal con 75.9%, y triple negativo con 65.6%. El grupo molecular luminal B redujo significativamente el riesgo de mortalidad a los 5 años (p=0.001; HR=0.093). Complementariamente, la quimioterapia (p=0.000; HR=0.123) y la radioterapia (p=0.004; HR=0.229) redujeron el riesgo de mortalidad; no obstante, la recurrencia incrementó drásticamente el riesgo de mortalidad.
Conclusión: La sobrevida a 5 años varía significativamente según grupo molecular de cáncer de mama; asimismo, al grupo molecular B reduce el riesgo de mortalidad en pacientes del Hospital Regional José Cayetano Heredia de Piura
Objective: Determine the 5-year survival of patients with breast cancer according to molecular group at the José Cayetano Heredia Regional Hospital in Piura, during the period 2015 - 2017. Methodology: It was an observational, analytical and retrospective cohort investigation, where a sample of 263 women with breast cancer selected by simple random probabilistic sampling was considered. The information was extracted from medical records and the instrument was a collection sheet made up of demographic, clinical, survival and molecular group data. Statistical analysis by Cox regression. Results: Five-year overall survival was 74.5%. Of all patients who survived at the end of follow-up, the majority were luminal A (39.3%) and luminal B (32.1%) subtype; Next, the triple negative (20.4%) and HER2 positive (8.2%) subtypes were found. The survival curve showed that the survival in the Luminal A molecular group was 79.4% at 5 years, followed by the HER2 group with a 76.2% survival at 5 years, Luminal with 75.9%, and triple negative with 65.6%. The luminal B molecular group significantly reduced the risk of mortality at 5 years (p=0.001; HR=0.093). Additionally, chemotherapy (p=0.000; HR=0.123) and radiotherapy (p=0.004; HR=0.229) reduced the risk of mortality; However, recurrence dramatically increased this risk of mortality. Conclusion: 5-year survival varies significantly depending on the molecular group of breast cancer; Likewise, molecular group B reduces the risk of mortality in patients at the José Cayetano Heredia Regional Hospital in Piura
