Orbital Exenteration: Tumour Diversity and Survival-Report from a Cancer Centre of Northeast India.

Abstract

Orbital exenteration is a mutilating surgery which involves the removal of the entire contents of the bony orbit, including the globe, extraocular muscles and periorbital fat, and many times includes the eyelids. Since it leads to severe disfigurement, it is an infrequent procedure largely indicated in malignant conditions. The current study aims to report the clinicodemographic profile and treatment outcome of orbital exenteration patients done in a cancer care center in Northeast India. This is a hospital-based retrospective study between January 2017 and December 2021, including patients undergoing orbital exenteration. All patient and treatment-related data were retrieved from the record of hospital files. A total of 18 patients were included in the study. The mean age of the patients was 51 ± 18 years and male: female ratio was 1:1. Most patients had primary in orbit (55.6%). The most common histology was squamous cell carcinoma, (8/18, 44.4%), followed by basal cell carcinoma (two patients, 11.1%). After a median follow-up was 25 months (range 3-92), the median DFS of the study population was 31.4 months. The five-year overall survival of the patients was 54%. Orbital exenteration is an infrequent surgery due to the associated disfigurement and hence reserved for conditions where eye preservation is impossible. We tried to report the experience of orbital exenteration from a single cancer center for five years.
