Comparing two diagnostic methods used for breast neoplasm in a cancer centre in Colima, Mexico

Objetivo Determinar la relación entre los hallazgos de tumores mediante mamografía
y el diagnóstico histopatológico de los mismos.
Métodos Se realizó un estudio transversal descriptivo. Participaron pacientes del
Centro Estatal de Cancerología de la ciudad de Colima, México. Los criterios de
inclusión fueron: mujeres con mamografía y calificación BIRADS; mujeres con biopsia
y diagnóstico histopatológico; mujeres de todas las edades, todos los estadios clínicos
y con expediente clínico completo. Para la estadística descriptiva se utilizaron las
frecuencias, porcentajes, promedios y desviación estándar. Para la estadística
inferencial se utilizaron las pruebas de t de Student, de chi cuadrada y el cálculo del
OR e IC (95 %).

Objective Determining the relationship between mammography neoplasm reports and histopathological diagnosis of neoplasms. Methods A descriptive cross-sectional study was carried out. Patients were included who were attending the state cancerology centre (Centro Estatal de Cancerología) in Colima, Mexico. Inclusion parameters were: females having mammography and BIRADS score of 1 or over; females having biopsy and histopathology diagnosis; females of all ages, all  clinic stages having a complete clinic record. Frequency, percentages, means and standard deviations were applied for descriptive statistics. Student's t-test, the Chi square test, OR and 95 %CI were applied for inferential statistics. Differences were considered to be significant when p<0.05. Results No relationship between a BIRADS score classified as being benign (BIRADS I-II-III) or malign (BIRADS IV-V) was found with histopathological results (benign or malign) (p=0.0666). Significant relationships by category were found in a separateanalysis: category IV (OR=0.024, 95 %CI=0.005-0.11, p=0.0007) and category V (OR=40.5, 95 %CI=9.03-181.3, p=0.0002). Conclusions I, III and V BIRADS scores had a relationship with histopathological diagnosis, while category II and IV BIRADS scores had no relationship. However, only categories 4 and5 were statistically significant.
