Genomic signatures in breast cancer in a real-world setting: Experience in a Brazilian Northeastern Center.

Objective: We aim to evaluate the indication and use of genomic signatures in breast cancer patients and outcomes who in patients undergoing adjuvant chemotherapy or not.

Methods: This is a retrospective study of breast cancer patients managed in a private oncology clinic in Teresina, from November 2014 to February 2021. All patients with an indication of genomic signature were included.

Genetic testing for hereditary predisposition to breast cancer in the real world: Initial experience.

Background: Around 5%-10% of breast cancers are due to hereditary breast and ovarian cancer syndrome. Genetic testing is important to identify these cases, enabling the adoption of specific risk-reducing treatment strategies.

Objective: To analyze the performance of genetic testing and its implications in patients with indication of genetic testing to identify hereditary predisposition to breast cancer.

Survival in metaplastic breast carcinoma: A case series.

Background: Metaplastic breast carcinoma (MBC) is a rare type of breast cancer (0.20-1.00% of all cases).

Lobular carcinoma of the breast with metastasis to the uterine cervix.

Metastases may occur in early-stage or locally-advanced tumors in diverse locations. Nevertheless, the uterine cervix is an uncommon site for metastasis, since the majority of tumors in this organ is primary carcinomas or result from the direct extension of primary pelvic tumors. The objective of the current study was to report a clinical case considered rare in the literature, as well as discuss its implications and peculiarities.
