SMARCB1-deficient sinonasal carcinoma is very locally advanced malignancy at diagnosis which often precluded upfront radical resection. The investigators are now proposing a phase II single-arm study on tazemetostat in combination with docetaxel, cisplatin and 5-FU (known as TPF regimen) as preoperative therapy for locally advanced non-metastatic SMARCB1 (INI-1)-deficient sinonasal carcinoma, followed by radical resection and/or post-operative radiation therapy (with or without concurrent chemotherapy), and tazemetostat for another 6 months. It is hypothesized that addition of tazemetostat will improve objective response rate, resectability rate, orbit preservation rate after surgery, and hopefully survival outcomes with manageable safety profiles.
