Abstract:
Objective:Retrospective analyzed the biological characteristics of the early stage nasal NK/T cell lymphoma in 30 cases and provide a reference for the contour of clinical radiotherapy target region.Methods:Thirty patients with pathologically confirmed nasal NK/T cell lymphoma from March 2005 to September 2013 were analyzed.All patients were stage as IE/IIE according to Ann Arbor criteria with imaging data available.Using imaging as standard to analyzed the adjacent organs and structures that were infiltrated,also metastasis of cervical lymph nodes.Results:The proportion of the infiltrated structures around the nasal cavity was 76.7%（23/30）of all patients.The infiltrated structures were as follows:maxillary sinus（36.6%）,ethmoid sinus（30%）,nasopharynx（30%）,nasal ala（20%）,pterygoid process（10%）,sphenoidal sinus（10%）,pterygopalatine fossa and frontal sinus,hard palate,orbit,oropharynx were 3.3% respectively.The proportion of cervical lymph nodes metastasis was 46.7%（14/30）of all patients:I (26.7%),II (26.7%),III (10%),VIIa (6.7%),IV and IX were 3.3% respectively.Conclusion:The infiltrated structures and regions with high rate should be considered during the radiotherapy of early stage nasal NK/T cell lymphoma.
