- Abstract
The optimal management of lobular carcinoma In Situ (LCIS) has largely been debated. This study evaluated practice patterns and outcomes in women diagnosed with LCIS at a single institution from 2000 to 2014. Patient characteristics, histology, method of diagnosis, and management were examined in relation to disease-free survival, and overall survival (OS). A total of 209 patients were identified. Surgical management in the majority of patients was excisional biopsy or local excision. Patients diagnosed with LCIS by core biopsy were less likely to have mastectomy as compared with other methods of initial diagnosis (P = 0.01). A total of 108 (90.8%) patients received chemoprevention (CP) counseling, and 47 (43.5%) used chemoprevention. Estimated five-year disease-free survival rate was 96.3 per cent (95% confidence interval (CI): 92.0-98.3%) and OS rate was 98.6 per cent (95% CI: 94.6-99.7%). Older age was associated with a higher risk of subsequent breast cancer (hazard ratio (HR): 1.04; 95% CI: 1.01-1.07; P = 0.01). Older age (HR: 1.06; 95% CI: 1.02-1.11; P = 0.004) and diagnosis in the earlier years of the study period (HR: 0.65; 95% CI: 0.48-0.89; P = 0.007) were significantly associated with worse OS in multivariate analysis. LCIS has a favorable prognosis and is most commonly managed conservatively.
