Abstract

Objective: To improve the quality of diagnosis, treatment, and prognosis for breast cancer in general and invasive lobular carcinoma (ILC) in particular. Subjects and methods: We conducted a retrospective descriptive study on 167 ILC patients who underwent a mastectomy at K Hospital from January 2019 to July 2023. Results: 5 subtypes of ILC according to the WHO 2019 classification were recorded. The classic type accounted for the highest rate with 94 cases, accounting for 56.3%; followed by the polymorphic type with 41 cases, accounting for 24.6%; then the cystic type with 14 cases, accounting for 8.4%; the solid type had 13 cases, accounted for 7.8%; tubular - lobular type accounted for the lowest percentage with 5 cases accounting for 3.0%. Histological grades of ILC (grades I, II, and III) were 11.4%, 70%, and 18.6%, respectively. Conclusion: The classic and pleomorphic subtypes are the most common in invasive lobular carcinoma, accounting for 80.9% of our study. Histological grade II is mainly with 56.3% of all.
