RESUMEN
Estudio prospectivo caso-control de factores de riesgo conocidos para cáncer de mama en grupo de pacientes femeninas con cáncer de mama, patología mamaria benigna y sin patología mamaria, para definir criterios clínicos que permitan orientar a los médicos y pacientes. Se incluyeron 515 pacientes con cáncer de mama, 507 con patología mamaria benigna y 505 sin patología mamaria. Se recogieron, con entrevista personal, los siguientes factores de riesgo: historia familiar de cáncer de mama y ovario, exposición a hormonas femeninas (exógena y endógena), antecedentes de patología mamaria benigna. Los resultados significativos al comparar el grupo con cáncer de mama y el grupo sin patología mamaria fueron los siguientes: antecedentes familiares de cáncer de mama y ovario, edad de la menopausia, nuliparidad, edad del primer embarazo a término, número de abortos, lactancia y antecedente de patología mamaria benigna. El modelo de regresión logística demostró que las variables de mayor impacto fueron los antecedentes familiares de cáncer de mama y ovario. Los resultados significativos al comparar el grupo con cáncer de mama y patología mamaria benigna fueron los siguientes: antecedente familiar de cáncer de mama “fuerte”, ingestión de anticonceptivos orales, lactancia, terapia hormonal de reemplazo, antecedente de patología mamaria benigna. El modelo de regresión logística demostró que la variable de mayor impacto fue la lactancia. Aunque algunos factores hormonales tuvieron importancia, la historia familiar de cáncer de mama, ovario, así como lactancia fueron los factores de mayor impacto.
ABSTRACT
A prospective case-control study was done considering known breast cancer risks factors in a group of female patients with breast cancer, benign breast diseases and without breast disease. The main objective was defining clinical criteria’s that help not only the physicians but also the patients with their parents about the clinical evaluation and the follow-up. Five hundred fifteen patients with breast cancer, 507 with benign breast disease, and 505 without breast disease were included. We registered, through personal interview, the following risk factors: family history of breast and ovarian cancer, exposition to female hormones (exogenous and exogenous) and previous benign breast disease. The significant results when we compared the group of breast cancer with the group without breast disease were as follows: family history of breast and ovarian cancer, age at menopause, null parity, and age at first live birth, number of abortions, lactation and previous benign breast disease. Logistic regression model showed that the most important variables were: family history of breast and ovarian cancer. The significant results when we compared the group of breast cancer with the group of benign breast disease were as follows: “strong” family history of breast cancer, oral contraceptives ingestion, lactation, hormone- replacement therapy and previous benign breast disease. Logistic regression model showed that the most important variable was lactation. Although some hormonal factors were important, family history of breast and ovarian cancer, and lactation were the most important risk factors.
