Introduction: Complications and readmissions derived from surgical treatment of breast cancer have been less evaluated than recurrence and mortality. The aim of this study was to analyze the results of surgical treatment and prognosis in a screening population with known high surgical variability.Methods: This multicenter study included 1086 women diagnosed with breast cancer from the CaMISS cohort study of women aged between 50 and 69years participating in four breast cancer screening programs in Spain between 2000 and 2009 with a follow-up until 2014. Multivariate models were used to estimate the adjusted odds ratio of breast surgery (mastectomy vs conservative treatment) for complications and readmissions and hazard ratios for recurrences and mortality.Results: Primary breast surgical treatment consisted of conservative treatment in 821 women (80.1%) and mastectomy in 204 (19.9%). Mastectomy was associated with readmissions, recurrences and mortality but this association was not statistically significant on multivariate adjusted analysis (ORa=1.51 [95%CI 0.892.57], HRa=1.37 [95%CI 0.852.19] and HRa=1.52 [95%CI 0.952.43] respectively). In our sample, the variables with greatest impact on complications, recurrences and mortality were stages III and IV (ORa=4.4[95%CI 1.2216.16], HRa=7.96 [95%CI 3.3219.06] and HRa=3.92[95%CI 1.778.67]).Conclusion: Complications, readmissions, recurrence and mortality were similar in both surgical techniques. These results support that surgical treatment for breast cancer can be adapted to professional and health system circumstances, and to the surgical needs and desires of each patient. At a time when screening programs are being questioned the variable with the greatest impact on mortality was stage III and IV. (AU)
Introducción: Las complicaciones y los reingresos derivados del tratamiento quirúrgico del cáncer de mama han sido menos evaluados que la recidiva y la mortalidad. El objetivo de este estudio ha sido analizar los resultados y el pronóstico del cáncer de mama en función del tipo de cirugía recibida en una población con elevada variabilidad quirúrgica.Métodos: En este estudio multicéntrico se incluyeron 1086 mujeres diagnosticadas de cáncer de mama de la cohorte CaMISS, con mujeres de entre 50 y 69 años participantes en 4 programas de cribado Españoles entre 2000 y 2009, con seguimiento hasta 2014. Se utilizó la regresión logística multivariada para estimar la odds ratio de complicaciones y reingresos. También modelos Cox para estimar hazard ratios de recidivas y mortalidad.Resultados: Se realizó cirugía conservadora en 821 mujeres (80,1%) y mastectomía en 204 (19,9%). La mastectomía se asoció con reingresos, recidivas y mortalidad, pero esta asociación no fue estadísticamente significativa en el análisis multivariado ajustado (ORa=1,51[IC95% 0,89-2,57], HRa=1,37[IC95% 0,85-2,19] y HRa=1,52[IC95% 0,95-2,43] respectivamente). La variable con mayor impacto sobre complicaciones, recidivas y mortalidad fue el estadio III/IV (ORa=4,4[IC 95%: 1,22-16,16], HRa=7,96[IC 95%: 3,32-19,06] y HRa=3,92[IC 95%: 1,77-8,67]).Conclusión: Las complicaciones, reingresos, recidiva y mortalidad fueron estadísticamente equivalentes en ambas técnicas quirúrgicas. El tratamiento quirúrgico del cáncer de mama puede adaptarse a las circunstancias profesionales, del sistema sanitario además de necesidades y deseos quirúrgicos de cada paciente. En un momento en que se cuestionan los programas de cribado, la variable con mayor impacto en mortalidad fue el estadio.

Introducción: Actualmente la variabilidad en la práctica quirúrgica constituye un problema a resolver. El objetivo de nuestro estudio es describir la variabilidad en la realización del tratamiento quirúrgico del cáncer de mama y analizar los factores asociados a la misma. Métodos: La población de estudio comprende 1.057 mujeres diagnosticadas de cáncer de mama y tratadas quirúrgicamente procedentes de la cohorte retrospectiva CaMISS. Resultados: La edad media en el momento del diagnóstico fue de 59,3 ± 5 años. Se diagnosticaron 732 pacientes mediante mamografías de cribado y 325 pacientes como cánceres de intervalo. La realización de mastectomía fue más frecuente en los tumores detectados entre intervalos (OR = 2,5; [IC 95%: 1,8-3,4]), aunque este efecto desaparece al ajustar por el resto de variables. El factor más determinante asociado a la realización de una mastectomía fue el TNM: los tumores con estadio iii-iv presentaron una OR de 7,4 (IC 95%: 3,9-13,8), aumentando en la OR ajustada hasta 21,7 (IC 95%: 11,4-41,8). Histológicamente el carcinoma lobulillar infiltrante mantiene la significación en la OR ajustada (Ora = 2,5; [IC 95%: 1,4-4,7]). Según el programa de cribado existen diferencias significativas en el tratamiento quirúrgico. El programa 3 presenta una ORa de cirugía tipo mastectomía de 4 [IC 95%: 1,8-8,9]. Este programa coincide con el de mayor porcentaje de reconstrucción (58,3%). Conclusiones: Este estudio muestra cómo a pesar de tener en cuenta las características de las pacientes y del tumor, existe una elevada variabilidad en el tipo de cirugía en función del lugar de diagnóstico
Introduction: Currently, variability in surgical practice is a problem to be solved. The aim of this study is to describe the variability in the surgical treatment of breast cancer and to analyze the factors associated with it. Methods: The study population included 1057 women diagnosed with breast cancer and surgically treated. Our data were from the CaMISS retrospective cohort. Results: The mean age at diagnosis was 59.3 ± 5 years. A total of 732 patients were diagnosed through screening mammograms and 325 patients as interval cancers. The mastectomy surgery was more frequent in the tumors detected between intervals (OR = 2.5; [95%CI: 1.8-3.4]), although this effect disappeared when we adjusted for the rest of the variables. The most important factor associated with performing a mastectomy was TNM: tumors in stage III-IV had an OR of 7.4 [95%CI: 3.9-13.8], increasing in adjusted OR to 21.7 [95%CI: 11.4-41.8]. Histologically, infiltrating lobular carcinoma maintains significance in adjusted OR (OR = 2.5; [95%CI: 1.4-4.7]). According to the screening program, there were significant differences in surgical treatment. Program 3 presented an OR of non-conservative surgery of 4.0 [95%CI: 1.8-8.9]. This program coincided with the highest percentage of reconstruction (58.3%). Conclusions: This study shows that, despite taking into account patient and tumor characteristics, there is great variability in the type of surgery depending on the place of diagnosis
