Abstract
e18573 Background: Lacrimal Gland (LG) tumors are rare with data limited to very few comparative trials. The original treatment is Orbital Exenteration followed by Radiotherapy (RT). Contemporary strategies like orbit sparing surgeries and Neoadjuvant Intra-arterial Chemotherapy (CT) are gaining popularity but remains controversial given the paucity of data. Our aim was to determine the pathological distribution and compare the treatment modalities used in LG tumors with the help of a large national database. Methods: From the 2004-2016 National Cancer Database (NCDB), we included Epithelial LG tumors. We excluded Lymphomas, Melanomas, Sarcomas and other metastatic lesions. Descriptive statistics, Hazard Ratio (HR) estimates and Kaplan Meier (KM) survival analysis were used. Results: A total of 669 LG tumors were identified. The distribution based on Pathology and treatment strategies used is represented in the table. The point survival estimate comparison between the surgical types and the various treatment groups showed no significance. Conclusions: SCC was the most common histological type. There was no difference in the overall outcome between radical and orbit sparing procedures. Adjuvant RT and adjuvant chemoradiation did not confer any additional survival benefit over surgery alone. Mallen-St Clair et. using the SEER database (321 LG patients) showed that RT improves Disease Specific Survival in SCC. Moving forward, larger population-based studies and prospective trials are needed to determine the most ideal management option. The NCDB is a joint project of the Commission on Cancer of the American College of Surgeons and the American Cancer Society. The data used in the study are derived from a de-identified NCDB file. The American College of Surgeons and the Commission on Cancer have not verified and are not responsible for the analytic or statistical methodology employed, or the conclusions drawn from these data by the investigator.
