| Abstract: | AIM: To analyze the differences in immune indicators and prognosis between IgG4-positive and negative lacrimal gland benign lymphoepithelial lesion (LGBLEL).METHODS: This was a single-center retrospective clinical study including 105 cases of IgG4-positive LGBLEL and 41 cases of IgG4-negative LGBLEL. Basic information, related indicators of peripheral venous blood samples using immunoscattering turbidimetry, treatment (partial surgical excision and glucocorticoid therapy) and prognosis (recurrence and death) were collected. Survival curves for recurrence were created using the Kaplan-Meier analysis. Univariate analysis and multivariate regression analysis were used to analyze prognostic factors.RESULTS: The mean age was 50.10±14.23y and 44.76±11.43y (P=0.033) in IgG4-positive and negative group respectively. The serum C3 and C4 was lower in IgG4-positive group (P=0.005, P=0.002), while the serum IgG and IgG2 was higher in IgG4-positive group (P=0.000 and P=0.008). Twenty-one cases had recurrence in IgG4-positive group and 3 cases recurrence in IgG4-negative group. The 5-year recurrence-free cumulative percentages of IgG4-positive group was 81.85%, and 83.46% in the IgG-negative group (P=0.216). The history of preoperative glucocorticoid therapy, serum C4, IgG1 and IgG2 were the factors affecting recurrence in IgG4-positive group, while serum C4, and IgG1 were the factors affecting recurrence of LGBLEL.CONCLUSION: Serum C4 and IgG1 are the factors affecting recurrence of LGBLEL, while the IgG4 does not affect recurrence of LGBLEL. |
