SYNCHRONOUS BILATERAL BREAST CANCER: A CASE REPORT

Apresentação do caso

R.F.P, a 49-year-old female pacient was referred to Liga Contra o Câncer Hospital with a mammography with evidence of amorphic calcifications measuring 4 cm in the right breast, the left breast with diffuse skin thickening, amorphic calcifications measuring 1,8 cm and lymph node with thickening in left axillary prolongation of 1,2 cm. She presented an US with a 1,5 cm nodule in the right breast, a 2,5 cm nodule in the left breast and a thickened lymph node in the left armpit. A core biopsy was performed and ductal carcinoma in situ was diagnosed in the right breast and non-special type invasive carcinoma in the left breast. The first-choice treatment consists of neoadjuvant chemotherapy, radical mastectomy of the left breast, simple mastectomy of the right breast, santinela lymph node biopsy in both armpits, and adjuvant radiotherapy in the letf breast.

Discussão

Bilateral synchronic breast cancer is defined as the simultaneous presence of 2 primary tumors at diagnosis or that are detected within the first 12 months of diagnosis of the first tumor. There is no consensus on the origin of synchronic neoplasia, which may be metastasis from a primary lesion or a second independent tumor. The first tumor to be diagnosed usually has a larger size when compared to the contralateral, in which most often it is diagnosed only by imaging. It is also important to emphasize that bilateral syncrhonich breast cancer was previously considered with a worse prognosis when compared to others, but more current data show similar survival among patients with unilateral cancer and patients with bilateral breast neoplasia when treated with conservative surgery combined with chemotherapy and radiotherapy.

Comentários Finais

Bilateral synchronich breast cancer is rare and has few cases described in the literature, especially in cases with different histological types. Contralateral breast screening by imaging such as US and mammography is essential for diagnosis. Conservative breast surgeries are viable options to be offered to patients without compromising survival.
