1Predictors of distant metastasis in acinic cell carcinoma of the parotid gland显示文摘BACKGROUND AiCC is a primarily indolent disease process.Our aim with this study is to determine characteristics consistent with rapidly progressive AiCC of the parotid gland.AIM To report on patients with metastatic lung disease from AiCC and potential correlative factors.METHODS Single-institution retrospective review of patients treated at the University of Michigan between 2000 and 2017.Univariate analyses were performed.RESULTS A total of 55 patients were identified.There were 6 patients(10.9%)with primary AiCC of the parotid gland who developed lung metastases.The mean age at diagnosis for patients with lung metastases was 57.8 years of age,in comparison to 40.2 years for those without metastases(P=0.064).All 6 of the patients with lung metastases demonstrated gross perineural invasion intraoperatively,in comparison to none of those in the non-lung metastases cohort.Worse diseasefree and overall survival were significantly associated with gross perineural invasion,high-grade differentiation,and T4 classification(P<0.001).CONCLUSION AiCC of the parotid gland is viewed as a low-grade neoplasm with good curative outcomes and low likelihood of metastasis.With metastasis,however,it does exhibit a tendency to spread to the lungs.These patients thereby comprise a unique and understudied patient population.In this retrospective study,factors that have been shown to be statistically significant in association with worse disease-free survival and overall survival include presence of gross facial nerve invasion,higher T-classification,and high-grade disease.Syed Ahmed Ali Kevin J Kovatch Jonah Yousif Sonali Gupta Andrew J Rosko Matthew E Spector 2020World Journal of Clinical Oncology2020,11,1:0
