摘　　要：BACKGROUND Sinonasal undifferentiated carcinoma(SNUC) is a rare aggressive tumor that is often unresectable. Optimal treatment for patients with unresectable,locally advanced SNUC(LA-SNUC) has not been established,and the patient outcome remains poor. We report two cases of unresectable LA-SNUC in which induction chemotherapy with docetaxel,cisplatin and fluorouracil(TPF) followed by radiotherapy with concurrent cisplatin(CCRT),a standard treatment option for locally advanced head and neck cancer,demonstrated promising outcomes.CASE SUMMARY A 39-year-old man presented with tearing and pain in the right eye. A biopsy of the tumor invading the sinonasal cavities,right orbit and cranial base confirmed the diagnosis of LA-SNUC. Induction TPF chemotherapy induced remarkable tumor shrinkage and rapidly improved the symptoms. He subsequently received CCRT and achieved complete remission of the disease. The other case is a 21-year-old man who presented with worsening vision. The unresectable tumor involving the nasal septum and cranial base was pathologically diagnosed as SNUC. TPF chemotherapy followed by CCRT yielded complete remission of the disease with preserved visual function. Both patients have been disease-free for44 mo.CONCLUSION Induction TPF chemotherapy followed by CCRT may remarkably improve the outcomes in LA-SNUC patients.BACKGROUND Sinonasal undifferentiated carcinoma(SNUC) is a rare aggressive tumor that is often unresectable.
