ABSTRACT
AIM:
To evaluate the survival outcomes of patients with lacrimal gland adenoid cystic carcinoma who underwent eye-sparing surgery combined with 125I seed implantation radiotherapy or local external γ-ray radiotherapy.METHODS:
In this retrospective comparative case series, the clinical records of 27 primary and 8 recurrent patients were reviewed. Univariate and multivariate analyses were used to identify risk factors associated with distant metastasis (DM), and the overall survival (OS) after the initial surgery was analyzed.RESULTS:
The median follow-up after radiotherapy was 36mo (range 6-120mo). At the last follow-up after radiotherapy, 26 (74.3%) patients had no evidence of disease, 7 (20%) patients had DM, 2 (5.9%) patients died of DM, and 1 patient with DM was lost to follow-up. Univariate analyses showed that duration of symptoms, bone destruction, T stage classification, and wide excision surgery were risk factors influencing DM (P<0.05). The 5-year and 10-year OS rates after the initial surgery were 95.8% and 79.9%, respectively. The 5-year DM-free survival and disease-free survival rates after radiotherapy were 66.4% and 52.7%, respectively.CONCLUSION:
125I seed radiotherapy and local external γ-ray radiotherapy may have similar therapeutic effects in preventing DM. Patients with T1/T2 stage disease have a better prognosis than those with T3/T4 stage disease.
