Purpose The extranodal natural killer (NK)/T-cell lymphoma (NKTCL) of non-upper aerodigestive tract (NUAT) was found to have clinical heterogeneity compared with NKTCL of the upper aerodigestive tract (UAT) in small scale studies. We conducted this study in a much larger cohort to analyze the clinical characteristics, prognostic factors, treatment modality, and clinical outcomes of patients with NUAT-NKTCL. Materials and Methods From January 2001 to December 2017, a total of 757 NKTCL patients were identified and included in this study, including 92 NUAT-NKTCL patients (12.2%) and 665 UAT-NKTCL patients (87.8%). Results NUAT-NKTCL patients had relatively poorer performance status, more unfavorable prognostic factors, and more advanced stage, compared with UAT-NKTCL patients. The 5-year overall survival (OS) was 34.7% for NUAT-NKTCL, which was significantly worse than UAT-NKTCL (64.2%, p < 0.001). The median OS duration was 30.9 months for NUAT-NKTCL. Multivariate analysis showed that presence with B symptoms and elevated serum lactate dehydrogenase independently predicted worse OS. International prognostic index score and prognostic index of NK lymphoma score still had prognostic values in NUAT-NKTCL, while the Ann Arbor system could not accurately predict the OS. Conclusion NUAT-NKTCL is a distinctive subtype of NKTCL in many aspects. Patients with NUAT-NKTCL have relatively poorer performance status, more unfavorable prognostic factors, more advanced stage, and poorer prognosis.

During the decommissioning of the nuclear facilities, the radioactive gases in pressure vessels may leakdue to the demolition operations. The decommissioning site has large space, slow air circulation, andmany large nuclear facilities, which increase the difficulty of workers' inhalation exposure assessment. Inorder to dynamically evaluate the activity distribution of radionuclides and the committed effective dosefrom inhalation in nuclear decommissioning environment, an inhalation exposure assessment methodbased on the modified eddy-diffusion model and the inhaled dose conversion factor is proposed in thispaper. The method takes into account the influence of building, facilities, exhaust ducts, etc. on thedistribution of radioactive gases, and can evaluate the influence of radioactive gases diffusion on workersduring the decommissioning of nuclear facilities.
