ABSTRACT

Se realizó un estudio descriptivo, transversal y prospectivo de 201 pacientes con cáncer de mama atendidos en el Servicio de Quimioterapia del Hospital Oncológico Docente Provincial "Conrado Benítez García" de Santiago de Cuba durante un año (de junio del 2013 a igual mes del 2014), a fin de caracterizarles y determinar la presencia de neutropenia como reacción adversa al tratamiento. La información fue analizada estadísticamente mediante el cálculo porcentual y la prueba de la Χ², con lo cual se obtuvo que 82 pacientes padecieran neutropenia (40,7 %), en quienes predominó el grupo etario de 41-60 años (50,0 %), el estadio clínico II del tumor maligno (65,8 %) y un único episodio de neutropenia (90,2 %). En cuanto a las pacientes diagnosticadas con neutropenia, se registraron 91 episodios, con mayor frecuencia de los grados moderado (52,7 %) y leve (39,5 %), y una reacción favorable al factor estimulante de colonias de granulocitos humano en 81,8 % de ellas. Por último, se demostró la existencia de neutropenia como efecto adverso a los citostáticos en casi 50 % de las pacientes, así como el resultado beneficioso del factor estimulante en estas; sin embargo, no se halló asociación entre las diferentes combinaciones de citostáticos y los episodios y grados de neutropenia.


A descriptive, cross-sectional and prospective study of 201 patients with breast cancer assisted in the Chemotherapy Service of "Conrado Benítez García" Teaching Provincial Oncological Hospital in Santiago de Cuba was carried out during a year (from June, 2013 to the same month of 2014), in order to characterize them and to determine neutropenia as adverse reaction to the treatment. The information was analyzed statistically by means of the percentage calculation and the test Chi squared test, with which it was obtained that 82 patients suffered neutropenia (40.7%) in whom the age group 41- 60 years prevailed (50.0%), the clinical stage II of the malignant tumor (65.8%) and just one neutropenia episode (90.2%). As for the patients diagnosed with neutropenia, 91 episodes were registered, with higher frequency of the moderated degrees (52.7%) and mild (39.5%), and a favorable reaction to the stimulating factor of human granulocytes colonies 81.8% of them. Lastly, the neutropenia existence as adverse effect to the cytostatic drugs in almost 50% of the patients was demonstrated, as well as the beneficial result of the stimulating factor in them; however, there was no association between the different combinations of cytostatic drugs and the episodes and neutropenia degrees.
