Key clinical point: Sonography features, such as spiculated morphology and antiparallel orientation, were significantly associated with worsened survival outcomes in patients with primary breast cancer (BC; tumor size <20 mm).
Major finding: The presence of spiculated morphology and antiparallel orientation on ultrasound was a significant risk factor for poor breast cancer-specific survival (hazard ratio [HR] 7.45; P < .001) and disease-free survival (HR 6.42; P < .001), with age ≥55 years (P < .05) and positive lymph node metastases (P < .001) also being associated with worse prognosis.
Study details: Findings are from a retrospective study including 790 women with small primary BC (tumor size <20 mm).
Disclosures: This study was supported by the National Natural Science Foundation of China and other sources. The authors declared no conflicts of interest.
