Key clinical point: Patients with breast cancer (BC) should be recommended to undergo primary breast surgery within 8 weeks from BC diagnosis for best survival outcomes.
Major finding: Overall survival outcomes were worsened by ≥15% when the interval between BC diagnosis and surgery was ≥9 weeks compared with 0-4 weeks (hazard ratio at 9 weeks 1.15; P < .001).
Study details: Findings are from a case series study including 373,334 female patients with stage I-III BC who underwent primary breast surgery.
