Initial breast cancer extension assessment using medical imaging

The study involved 502 patients, 494 of whom were women (98.41%) and 8 men (1.59%), with an average age of 48.53 years. A family history of breast cancer was found in 4.38% of patients. The infiltrating carcinoma was non-specific (90.84%) and grade II SBRm in 69.32% of patients. Tumor involvement predominated in the left breast (48.21%). Stage T3/T4 predominated, accounting for 85.06% of cases. 99% of patients had benefited from diagnostic imaging consisting of mammography and/or breast ultrasound, with only the 5 cases of necrotic ulcerated tumours not having undergone diagnostic work-up. In our study, 93.62% of cancers diagnosed were classified as BIRADS 4 or 5 on imaging. Tumors initially classified as BIRADS 3 (5.38%) turned out to be breast cancers. In the initial extension work-up, 77.29% of patients underwent a thoraco-abdomino-pelvic CT scan, 55.18% underwent abdominal ultrasound and 51% underwent chest radiography. Only 16 patients (3.19%) underwent scintigraphy.
