| dc.description.abstract | Background: breast cancer represents the most frequent neoplasia among women worldwide.
Breast Magnetic Resonance is an imaging study with enormous value in diagnosis, staging,
and treatment, being a tool that provides information on tumor size, degree of local extension,
multifocality, multicentricity, bilaterality, among others, many times not provided by other
imaging studies.
Objective: to describe the findings of Breast Magnetic Resonance in the assessment and
preoperative staging in patients diagnosed with breast cancer SOLCA, Cuenca, 2016-2019.
Methods: quantitative, observational, descriptive and retrospective study with 131 patients
with breast cancer. Medical records were reviewed and the different variables were recorded
using a form. Statistical analysis was performed using the SPSS 15 program, the results were
presented using frequencies, percentages, mean, standard deviation, asymmetry, kurtosis,
and the Kolmogórov-Smirnov test.
Results: Average age was 47 years, 54.20% were married. The most frequent level of
education was secondary (33.59%), the majority had urban residence (90.08%) 57.26% were
multiparous, 57.25% had exposure to hormonal contraceptives, and 19.08% had a family
history of breast cancer. The most frequent histological type was ductal carcinoma (78.63%)
and molecular type Luminal B (41.98%) 87.79% had BI-RADS VI classification. The most
frequent imaging finding was malignant-looking axillary lymph nodes (30.53%). 30.53%
underwent total mastectomy. Change in therapeutic attitude was 41.98%.
Conclusions: MRI determines additional findings more frequently in ductal and lobular
carcinoma and allows adequate preoperative planning. | |
