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 *** 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 *** Induction TPF chemotherapy followed by CCRT may remarkably improve the outcomes in LA-SNUC patients.

The objective of this study is to experimentally examine the characteristics of transient vortices in the boundary layer on a disk undergoing both rotation and orbital motion. The velocity fluctuations on a rotating, orbiting disk （disk radius equal to orbital radius） are measured by the hot-wire method, and the effects of orbital motion on the transient vortices in the boundary layer are examined. When the ratio of the orbital speed to the speed of rotation is i-0.025, the interval of transient vortices depends on only the orbital radius, regardless of the directions of rota- tion and orbital motion. The rate of low-frequency disturbances increases as the orbital speed increases, and the vortices induced by these low-frequency disturbances travel over the disk and then develop in the region of in- creased velocity. Consequently, no vortices generated on a rotating disk under orbital motion are stationary rela- tive to the disk.
