The authors declared that this study has received no financial support. “The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.” Voluntary consent form was given to patients or official guardians of deceased patients to use file information. File information was used after the forms were signed by the patient or official guardians of deceased patients. Abstract: Purpose: The literature contains differentiating information regarding the prognosis of invasive lobular carcinoma. We aimed to address the inconsistency by comparatively examining the clinical features and prognosis of invasive lobular carcinoma patients in our university and to report our experience by dividing our patients into various subgroups. Patients and methods: Records of patients with breast cancer admitted to Trakya University School of Medicine Department of Oncology between July 1999 and December 2021 were reviewed. The patients were divided into three groups (No-Special Type Breast Cancer, Invasive Lobular Special Type BC, No-Lobular Special BC). Patient characteristics, treatment methods and oncological results are presented. Survival curves were generated using the Kaplan–Meier method. Statistical significance of survival among the selected variables was compared by using the log-rank test. Results: The patients in our study consisted of 2142 female and 15 male breast c
