Key clinical point: Invasive lobular carcinoma (ILC), the most common special histological type of breast cancer (BC), had poorer survival outcomes than invasive ductal carcinoma (IDC) and no-lobular special type BC.
Major finding: Patients with ILC vs no-lobular special type BC and IDC had the shortest duration of both disease-free survival (197.2 vs 216.7 and 226.5 months, respectively) and overall survival (209.8 vs 227.9 and 233.2 months, respectively), and ILC vs IDC was associated with significantly worse overall survival (hazard ratio 1.45; P = .045).
Study details: Findings are from a retrospective study including 2157 patients with invasive carcinoma of the breast who were categorized into IDC (n = 1814), ILC (n = 193), and no-lobular special type BC (n = 150).
Disclosures: This study did not receive any specific funding. The authors declared no conflicts of interest.
