OBJECTIVE:
To explore the clinical feature, the reason of misdiagnosis and mistreatment, influential factor of prognosis in patients with extranodal NK/T cell lymphoma-nasal type.
METHOD:
A retrospective study was made on the clinical data of 34 patients with extranodal NK/T cell lymphoma-nasal type. Among them, 10 cases were staged I(E) intra-cavity, 15 cases were I(E) ex-cavity, 6 cases were II(E) and 3 cases were IV(E). Among them, 29 cases were in nasal cavity, 5 cases were outside nasal cavity; 14 cases were treated with single chemotherapy or radiation therapy, 20 cases were treated with radiation therapy add chemotherapy.
RESULT:
The total rate of misdiagnosis and mistreatment were 58.8% (20/34), 52.3% (18/34), respectively. The 5-year survival rate of the I(E) intra-cavity group were 60.0% (6/10), and those of I(E) ex-cavity group were 26.7% (4/15), and those of II(E) group and IV(E) group were 16.7% (1/6), 0% (0/3), respectively There was significant difference between 3 groups by statistical analysis (P < 0.01). The 5-year survival rate of I(E) ex-cavity group treated with single therapy were 0% (0/6), and those of I(E)-cavity group treated with combined therapy were 50% (1/2).
CONCLUSION
The early clinical manifestation of extranodal NK/T tell lymphoma-nasal type is atypical and which is hard to diagnose and treat. Diagnosis depends on pathologic biopsy and immunohistochemistry, there are many factors that influence the prognosis of this disease, in which the clinical stage is a major factor. It is crucial for diagnosing and treating early.

Objectives:To explore the effects of interatrial shunt on cardiac function and clinical prognosis of patients with heart failure with reduced ejection fraction(HFrEF). Methods:This study was a prospective single-arm study.From December 2021 to December 2022,15 consecutive patients with HFrEF from Beijing Anzhen Hospital were enrolled in this study.Interatrial shunt was performed with a D-Shant atrial shunt device.Right heart catheterization was performed before and immediately after device implantation,pulmonary capillary wedge pressure(PCWP),mean right atrial pressure(RAP),interatrial gradient pressure,mean pulmonary artery pressure,total pulmonary resistance(TPR),pulmonary vascular resistance(PVR),cardiac index(CI),and pulmonary/systemic blood flow ratio(Qp/Qs)were measured.Patients were followed-up for 12 months after procedure,changes in cardiac structure and function were evaluated by echocardiography.NYHA classification,6-minute walking distance(6MWD),and Kansas City cardiomyopathy questionnaire(KCCQ)were observed.All-cause mortality and rehospitalization for heart failure served as clinical endpoints. Results:Interatrial shunt procedure was successful in all patients.Compared with preoperative value,PCWP,interatrial gradient pressure,mean pulmonary artery pressure,and TPR were significantly decreased,while Qp/Qs was significantly increased immediately after procedure(all P<0.01).There were no significant changes in RAP,PVR,and CI post procedure(all P>0.05).There were no significant differences in shunt size,shunt velocity,and shunt pressure difference between postoperative immediately and at 12-months follow-up(all P>0.05).At 12 months,left ventricular ejection fraction was significantly higher than baseline level(P<0.05),and there were no significant changes in right atrial diameter and right ventricular fractional area change(both P>0.05).Compared with preoperative status,NYHA classification was improved,KCCQ score was increased,and the number of patients with 6MWD>450 m was increased at 12 months(all P<0.05).N-terminal pro-B-type natriuretic peptide value was significantly decreased at 12 months(P<0.05).No patient died during the 12-months follow-up period,and there were no device-related adverse events.Two patients experienced hospital readmission for heart failure. Conclusions:Implantation of interatrial shunt device could effectively improve hemodynamic parameters in patients with HFrEF and is related to significantly improved cardiac function at 12-months follow-up.
