Clinicopathological features of patients with wide local excision of eyelid malignant neoplasms: a more than five years retrospective study from China

Abstract

Background: To investigate the correlation between the clinical and pathological characteristics and outcomes in patients with eyelid malignant tumors underwent wide local excision.Methods: This retrospective study included 141 cases of eyelid malignant neoplasms from January 2010 to December 2015 in Shanxi eye hospital. Demographic and clinical information were collected. The Kaplan-Meier method was used to calculate survival curves, and the log-rank test method was used to compare survival between groups. Cox proportional regression models were used to calculate the hazard ratios (HR) of total recurrence rate and metastasis rate.Results: Overall, there were 141 eyelid malignant neoplasms cases aged 65.00 ± 9.69 (range, 41 - 88) years old. The duration time range was from 1 to 828 (61.09 ± 122.21) months. Basal cell carcinoma (BCC) is the most common of all eyelid malignancies, accounting for 84 (59.5%), followed by Sebaceous gland carcinoma (SGC, 41, 29%), Squamous Cell Carcinoma (SCC, 11, 7.8%), Malignant Melanoma (MM, 3, 2.1%)。On cox-regression analysis, pathological classification (HR 1.959; 95% CI 1.012-3.790; p=0.046) and eyelid tumor surgery history (HR 17.168; 95% CI 1.889-156.011; p=0.012) were independently associated with recurrence in patients with eyelid malignant neoplasm. Pathological classification (HR 2.177; 95% CI 1.423 -3.331; p<0.001) was independently associated with metastasis in patients with eyelid malignant neoplasm. Recurrence and metastasis were most likely to occur in 3 years after surgery. Conclusion: Wide local excision is an effective and economical treatment for eyelid malignant neoplasms. The prognosis is mainly related to pathological types, eyelid tumor surgical history and TNM stages.
