Abstract
Identificar las Características clínico-epidemiológicas en mujeres con cáncer de mama en el Instituto Regional de Enfermedades Neoplásicas - IREN Norte en los años de 2019 a 2021. Materiales y métodos: estudio observacional, descriptivo de corte transversal, se recolectó 135 historias clínicas. Resultados: la edad media de las mujeres fue 56 años; el 80% fueron multíparas; la edad media de menarquia fue 13 años, de menopausia fue de 46 años; el 85 % se encontraron desocupadas, el 45 % tuvieron secundaria; 61,48% procedían de La Libertad; la edad media de la primera gestación fue 22 años; el 43,7% tuvo sobrepeso, el 97% no consumía alcohol y el 99% no fumaba, el 62 % no presentó antecedentes familiares. El estadio de cáncer más común (25%) IIIB, el subtipo luminal B como el más común con un 33%, el 90% presentó carcinoma ductal infiltrante como tipo histológico y la quimioterapia fue la terapia inicial más usada. Conclusiones: la edad media fue 56,6 años, edad media de menarquia fue de 13,16 años; de menopausia 46,17 años y de primera gestación fue 22,38 años. Prevaleció la multiparidad, la desocupación, grado de instrucción secundaria, procedencia de La Libertad, el sobrepeso, no consumo de alcohol ni tabaco y ausencia de antecedentes familiares en primer grado de cáncer de mama. Lo más frecuente fue el cáncer de mama en estadio IIIB, el subtipo molecular luminal B, el carcinoma ductal invasivo, la quimioterapia como tratamiento inicial y la respuesta parcial al tratamiento.

Abstract identify the clinical-epidemiological characteristics of women with breast cancer at the Regional Institute of Neoplastic Diseases (IREN Norte) from 2019 to 2021. Materials and Methods: This is an observational, descriptive cross-sectional study involving 135 medical records. Results: The mean age of the women was 56 years; 80% were multiparous; the mean age at menarche was 13 years, and at menopause, 46 years. A total of 85% were unemployed, 45% had completed secondary education, and 61.48% were from La Libertad. The mean age at first pregnancy was 22 years. Additionally, 43.7% were overweight, 97% did not consume alcohol, and 99% were non-smokers. Family history of breast cancer was absent in 62% of cases. The most common cancer stage was IIIB (25%), with the luminal B subtype being the most prevalent (33%). Infiltrating ductal carcinoma was the most frequent histological type (90%), and chemotherapy was the most commonly used initial therapy. Conclusions: The mean age was 56.6 years, the mean age at menarche was 13.16 years, at menopause 46.17 years, and at first pregnancy 22.38 years. Multiparity, unemployment, secondary education level, origin from La Libertad, overweight, no alcohol or tobacco consumption, and absence of first-degree family history of breast cancer predominated. The most frequent findings were stage IIIB breast cancer, the luminal B molecular subtype, invasive ductal carcinoma, chemotherapy as the initial treatment, and partial response to treatment.
