Objective To investigate the telephone information-memory-concentration test (TIMCT) in evaluating the cognitive function of patients with nasopharyngeal carcinoma(NPC)after radiotherapy. Methods The cognitive function were evaluated by TIMCT and mini mental state examination (MMSE) in 2 weeks for 30 normal persons and 90 NPC patients. And the 90 NPC patients were divided into the 3 months, 2 years and 5 years after radiotherapy groups. All patients were carried out firstly face to face interview and telephone interview 1 time after 2 weeks. Results The correlation coefficient of all groups between TIMCT(telephone) and TIMCT (face to face) were bigger (R = 0.850) when MMSE wasn't control variable. And the correlation coefficients between TIMCT (telephone) and TIMCT (face to face) were lower (R = 0.366) when MMSE was control variable. As for examining time was classification factor, TIMCT (telephone) and TIMCT (face to face) were analyzed by partial correlation analysis. Only normal group was correlated with group of 3 months after radiotherapy and group of 2 years after radiotherapy wasn't correlated with group of 5 years after radiotherapy (R = 0.447,0.970,0.200 and 0.062). In addition, the difference plot of TIMCT(telephone) and TIMCT (face to face) indicated that telephone was consistent with face to face interview (MMSE≥28). Both telephone and face to face interview reflected the cognitive function downtrend of rescareh objects. Conclusions TIMCT (telephone), TIMCT(face to face) and MMSE (face to face) can reflect cognitive function downterend of patients with NPC after radiotherapy. But TIMCT(telephone) used in clinical screening cognitive function impairment of patients with NPC after radiotherapy should be improved further.

Objective:To investigate the combining therapy which not only have cured effect but also can uphold and improve the NPC patient′s immunity function after radiotherrapy and chemotherapy.Method:90 cases randomly divided into 3 groups ①Local group (local injected with IL-2 +radiotherapy+chemotherapy);②General group(ivdrip with IL-2+radiotherapy+chemotherapy);③convention group(radiotherapy+chemotherapy).Checked and observed the immunity function around the immunotherapy and after the radiotherapy and chemotherapy.Result:Cellular immunity of 3 groups are lower and humoral immunity are hypetuntion than normal person.After treated with IL-2 the cellular immunity improves but there′s no great change of the humoral immunity. The immune status of the immune groups have not obvious change than before radiotherapy,at the same time,the cellular immunity of the convention group cut down and the humoral immunity doesn′t change obviously.Conclusion:①It has some effect to uphold and improve the NPC patient′s immunity function to treat with small dosage of IL-2 before radiotherapy and chemotherapy,general treatment is better than local injection;②The three therapies have not great influence on the patient′s humoral immunity.

Objective To investigate the use of NBI (narrow band imaging) in early the diagnosis of nasopharyngeal carcinoma.Methods A total of 55 cases with nasopharyngeal lesions (including 9 cases of nasopharyngeal carcinoma after treatment) were examined and diagnosed by white and NBI endoscopy between October 2011 and March 2012,and their diagnosis efficacies were evaluated based on pathological diagnosis as a gold standard.Chi-square test was used to analyze data.Results Of 55 cases,12 cases were pathologically diagnosed as chronic mucosa inflammation and 43 as nasopharyngeal carcinoma including 6 recurrent cases,of 43 cases,40(93.0％) were diagnosed by NBI endoscopy and 18 (41.9％) by white endoscopy.Of 12 cases with early nasopharyngeal carcinoma (5 for stage Ⅰ and 7 for stage Ⅱ),5(100.0％) for stage Ⅰ,and 6 (85.7％) for stage Ⅱ were diagnosed by NBI endoscopy but only 1(14.3％) for stage Ⅱ by white endoscopy,with a statistically significant difference (x2 =10.000,P =0.008 ;x2 =7.143,P =0.029).Conclusion NBI endoscopy can be used in early diagnosis of nasopharyngeal carcinoma and check after treatment.

OBJECTIVETo investigate the method of surgical treatment via trans-nasal endoscopic approach in osteoradionecrosis of skull base after radiotherapy for nasopharyngeal carcinoma.

METHODSFifteen patients with osteoradionecrosis of skull base after radiotherapy for nasopharyngeal carcinoma who underwent operation via trans-nasal endoscopic approach from 2008 to 2013 were retrospectively reviewed. The typical clinical manifestations included headache (NRS 6-9: 11 cases), foul odor (10 cases), epistaxis (4 cases), hearing loss (5 cases, 7 ears), tinnitus (4 cases, 5 ears). All patients underwent operation via trans-nasal endoscopic approach. During the operation, the diseased region was fully exposed, the necrotic tissue was resected, the necrotic bone was removed by high-speed electric drill, and the drainage was made unobstructed. The perioperative treatment and follow-up were carried out.

RESULTSAfter operation, all patients were diagnosed pathologically as osteoradionecrosis and mucosal chroinic inflammation, 1 case combined with fungal sphenoid sinusitis. Headache (9 cases) and foul odor (9 cases) resolved after operation. The follow-up was lasted 18-82 months, 13 cases were survival, 1 case lost to follow-up, 1 case died of cerebral hemorrhage.

CONCLUSIONSurgical treatment via trans-nasal endoscopic approach is safe and effective in osteoradionecrosis of skull base after radiotherapy for nasopharyngeal carcinoma, and is helping to improve the survival rate and survival quality.

OBJECTIVETo evaluate the efficacies of different treatments for recurrent cervical lymph nodes and the factors contributing to prognosis in patients with nasopharyngeal carcinoma after radiotherapy.

METHODSClinical data of 79 patients with nasopharyngeal carcinoma after radiotherapy were retrospectively analyzed, and all cases were diagnosed as having recurrent cervical lymph nodes by pathological examination. The factors including sex, age, the interval between completion of radiotherapy and recurrence, rN stage, treatment methods, and the location relationship between recurrent lesion and primary tumor in the neck were analyzed for prognosis. Kaplan-Meier curves, Log-rank test and Cox's proportional hazards regression mode were used in the statistical analysis.

RESULTSThe median recurrence time was 26 months, and the 1- , 3- and 5-year overall survival rates were 77.9%, 53.4% and 39.7%. Cox's proportional hazards regression mode analysis indicated that age, rN stage, treatment methods, and the location relationship between recurrent lesion and primary tumor were significantly prognostic factors.

CONCLUSIONSNeck dissection is superior to re-radiotherapy in treatment of recurrent cervical lymph nodes in nasopharyngeal carcinoma after radiotherapy. The patients younger than 45 years old, in early rN stage and for recurrence in the center region of primary tumor have a better prognosis.
