ABSTRACT
OBJETIVO: Describir y analizar, según la vía diagnóstica, las características de los tumores de cáncer de mama. Se analizan los efectos adversos de los tratamientos recibidos y la utilización de terapias no convencionales para paliarlos. MÉTODO: Diseño descriptivo anidado en cohorte mixta (Cohorte DAMA). La variable dependiente fue la vía diagnóstica del cáncer de mama. Las variables independientes fueron la edad, el índice de masa corporal, la clase social, con renta familiar disponible, el tipo de tumor, el grado histológico, el estadio tumoral, las recidivas, el tratamiento, los efectos adversos de los tratamientos y las terapias no convencionales. Se realizaron análisis descriptivos bivariados y se ajustaron modelos de regresión univariados y multivariados, y se hicieron representaciones gráficas de la frecuentación de terapias no convencionales. RESULTADOS: Existen diferencias en las características de los tumores y en el impacto de los efectos adversos derivados de los tratamientos. Las pacientes diagnosticadas por cribado fueron de mayor edad y de clase social alta, presentaron un mayor porcentaje de tumores de grado I histológico, estadios iniciales, menos recidivas y efectos adversos debidos al tratamiento, aunque este no fuera distinto en el grupo de cribado respecto al resto. También hubo un menor uso de terapias no convencionales. CONCLUSIONES: Los resultados indican que la implantación de programas de cribado aumenta la posibilidad de detectar tumores en etapas iniciales y con terapias con menos efectos adversos; en consecuencia, con menor necesidad de recurrir a terapias no convencionales
OBJECTIVE: To describe and analyze the characteristics of breast cancer tumours according to the diagnostic pathway. We analyse the adverse effects of the treatments and the use of unconventional therapies in order to alleviate them. METHOD: Descriptive design nested in a mixed cohort (Cohort DAMA). The dependent variable was the route to diagnosis of breast cancer. The independent variables were age, body mass index, social class, disposable family income, type of tumour, histological degree, tumour stage, recurrences, treatment, adverse effects derived from treatments and unconventional therapies. Bivariate descriptive analyses were performed and univariate and multivariate regression models were adjusted; and graphic representations of the unconventional therapies. RESULTS: There are differences in the characteristics of the tumours, and the impact of the adverse effects derived from the treatments. The patients diagnosed by screening were older, from a high social class, had a higher percentage of tumours of grade I differentiation, initial stages, fewer recurrences and fewer adverse effects due to treatment, although this was not different in the screening group compared to the rest. There was also less use of unconventional therapies. CONCLUSIONS: The results indicate that the implementation of screening programmes increases the possibility of detecting tumours in initial stages and with therapies with fewer adverse effects. As a result, there is less need to resort to unconventional therapies
