Conventional well-differentiated, dedifferentiated, and myxoid liposarcomas have long been known to harbor numerous typical genetic alterations that allow for diagnosis of these tumors. These include MDM2 and CDK4 amplification in well-differentiated and dedifferentiated liposarcomas as well as FUS-DDIT3 rearrangements in myxoid liposarcoma. More recently, in-frame TRIO-TERT fusion genes have been described in a subset of non-translocation-related sarcomas including myxofibrosarcoma, dedifferentiated liposarcoma, undifferentiated pleomorphic sarcoma, pleomorphic rhabdomyosarcoma, and leiomyosarcoma. These genetic rearrangements lead to TERT mRNA expression levels hundreds of times higher than normal, causing increased telomerase activation in these tumors. Herein, we describe an unusual case of a liposarcoma with spindle cell features and a TRIO-TERT fusion transcript identified through next-generation sequencing.

Sanger Sequencing and immunohistochemistry was employed to investigate the TERT promoter mutations and TERT protein expression with their association to clinicopathological characteristics in over 2200 samples of Middle Eastern origin from 13 different types of cancers. The TERT promoter mutations were most frequently present in bladder cancer (68.6%), followed by central nervous system tumors (28.7%), thyroid cancer (15.4%), prostate cancer (9.3%), endometrial carcinoma (3.7%), rhabdomyosarcoma (1.4%), colorectal cancer (1%), epithelial ovarian carcinoma (0.7%) and breast cancer (0.7%). No mutations were observed in other types of cancers. In bladder cancer, we found significant inverse association with metastasis and a trend to good survival in patients with TERT mutations. In gliomas, TERT promoter mutations predicted poor prognosis. In thyroid cancer, high frequency of TERT mutation was observed in poorly differentiated carcinoma. In addition, TERT promoter mutations were associated with aggressive markers and poor outcome in follicular thyroid carcinomas.
