ABSTRACT

Purpose@#This study was aimed to investigate long-term survivals and toxicities of early-stage nasopharyngeal carcinoma (NPC) in endemic area, evaluating the role of chemotherapy in stage II patients. @*Materials and Methods@#Totally 187 patients with newly diagnosed NPC and restaged American Joint Committee on Cancer/ International Union Against Cancer 8th T1-2N0-1M0 were retrospectively recruited. All received intensity-modulated radiotherapy (IMRT)±chemotherapy (CT) from 2001 to 2010. @*Results@#With 15.7-year median follow-up, 10-year locoregional recurrence-free survival, distant metastasis-free survival (DMFS), disease-specific survival (DSS), and overall survival (OS) were 93.3%, 93.5%, 92.9% and 88.2%, respectively. Multivariable analyses showed cervical lymph nodes positive and pre-treatment prognostic nutritional index ≥ 52.0 could independently predict DMFS (p=0.036 and p=0.011), DSS (p=0.014 and p=0.026), and OS (p=0.002 and p 45 years (p=0.002) and pre-treatment lactate dehydrogenase ≥ 240 U/L (p 0.05). Unsurprising, patients in IMRT+CT had more acute gastrointestinal reaction, myelosuppression, mucositis, late ear toxicity, and cranial nerve injury (all p < 0.05) than IMRT alone group. @*Conclusion@#Superior tumor control and satisfying long-term outcomes could be achieved with IMRT in early-stage NPC with mild late toxicities. As CT would bring more toxicities, it should be carefully performed to stage II patients.

ABSTRACT

Objective The internationalization of modern scientific research and its high degree of complexity have showed the importance of scientific research cooperation.How to promote cooperation more effectively is an important research topic.Methods This article analyzes the research cooperation of Institute of Hematology & Blood Diseases Hospital Chinese Academy of Medical Sciences during the past 12 years.Results Scientific research cooperation is a big trigger for the output of papers,especially high-level output,international and native institutions' cross-cooperation can be used as an important way for expanding scientific research cooperation and provides a reference for decision-making.Conclusions Strengthen the awareness of cooperation,increasing scientific research funding,establishing common and hot research directions and constructing highlevel platform can expand scientific research cooperation.

ABSTRACT

Anterior communicating artery aneurysms (ACoAA) accounts for about 30% of all intracranial aneurysms, and their occurrence and morphology are closely related to A1 segment of anterior cerebral artery. The dominant blood supply of A1 segment of unilateral anterior cerebral artery and the angle between A1 segment and A2 segment are important factors for the formation and development of ACoAA. The aneurysmal orientation of ACoAA is closely related to the morphological features of the A1 segment of the dominant anterior cerebral artery. The morphology of the A1 segment of anterior cerebral artery has an important effect on treatment and outcome of ACoAA.

ABSTRACT

Objective To evaluate the validity and reliability of the Chinese version of Xerostomia Questionnaire ( XQ-C) in nasopharyngeal carcinoma patients treated with radiotherapy. Methods XQ-C was translated according to the International Quality of Life Assessment project approach. Patients with nasopharyngeal carcinoma in different radiotherapy stages were enrolled in this study and assessed by using the XQ-C. The validity and reliability of the questionnaire results were evaluated. The content validity was assessed by experts grading method. The construct validity was assessed by exploratory factor analysis. The discriminant validity was determined by non-parametric method. The reliability was evaluated by Cronbach′s α and split-half reliability to assess the internal consistency. Results A total of 212 questionnaires were completely filled out. Content validity showed that the item content validity index ( I-CVI) ≥0.80, Scale-CVI/Ave=0.97, and P value of Kendall′s W test was 0.701. Exploratory factor analysis revealed that XQ-C was a unidimensional scale. The scale scores of patients at different stages of radiotherapy significantly differed, suggesting that the discriminant validity was good. Cronbach′s α of the scale was 0.951 and Guttman′s semi-reliability coefficient was 0.940. Conclusion The XQ-C is valid and reliable, which can be widely applied in the clinical diagnosis, treatment and research of xerostomia in Chinese nasopharyngeal carcinoma patients after radiotherapy.

ABSTRACT

Objective To investigate the efficacy and tolerability of dose-dense chemotherapy with cisplatin plus 5-fluorouracil( PF regimen)in distant metastatic nasopharyngeal carcinoma( NPC)patients. Methods From April 1,2008 to April 30,2014,168 patients were assigned to traditional group(n = 83) and dose-dense group(n = 85)using digital random table in 1 : 1 ratio. All patients received PF regimen,and once every 28 days in traditional group and once every 14 days in dose-dense group. The primary endpoint was progression-free survival(PFS)and the secondary endpoint was overall survival(OS),toxicity and response rate. Results The median PFS,median OS,1,2,3-year survival rate,complete response rate and objective response rate were significantly improved in dose-dense group which were 13. 3 months,20. 2 months,80. 2% , 36. 0% ,16. 1% ,16. 5% ,84. 7% ,and those in control group were 10. 0 months,16. 1 months,59. 6% , 10. 1% ,0,3. 6% ,54. 2% respectively(χ2 = 24. 47,P = 0. 000;χ2 = 16. 65,P = 0. 000;χ2 = 8. 41,P =0. 004;χ2 = 16. 96,P = 0. 000;χ2 = 14. 91,P = 0. 000;χ2 = 7. 63,P = 0. 006;χ2 = 18. 47,P = 0. 000). The rates of grade 3-4 adverse events in dose-dense and traditional group were 38. 8% and 6. 0%(χ2 = 25. 81, P = 0. 000). Conclusion Dose-dense chemotherapy of PF is more efficient and acceptable toxic than the tra-ditional one. It can be a new treatment option for patients with distant metastases of NPC.
