Long-term efficacy and adverse reactions of intensity-modulated radiotherapy for patients with nasopharyngeal carcinoma in non-endemic northwest China / 中华放射肿瘤学杂志

Objective@#To retrospectively analyze the characteristics of nasopharyngeal carcinoma, long-term efficacy, adverse reactions of intensity-modulated radiotherapy (IMRT) in non-endemic northwest China and summarize the experience of IMRT in the treatment of nasopharyngeal carcinoma in the past decade.@*Methods@#Clinical data of 658 patients newly diagnosed with nasopharyngeal carcinoma without distant metastasis admitted to First affiliated hospital from January 2006 to December 2016 were retrospectively analyzed. All patients were treated with IMRT. The survival analysis was performed by Kaplan-Meier method. The multivariate analysis was conducted with Cox’s regression model.@*Results@#In non-endemic northwest China, a large proportion of patients were newly diagnosed with locally advanced nasopharyngeal carcinoma, and a majority of them were pathologically characterized as differentiated subtypes. The 5-year overall survival (OS), disease-free survival (DFS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS) and distant metastasis-free survival (DMFS) rates were 75.7%, 70.1%, 91.2%, 97.0% and 81.0%, respectively. Multivariate analysis showed that age, pathological type, nasopharyngeal tumor volume>23 cm3 and neck lymph node metastasis complicated with necrosis were the factors of poor prognosis of DFS (all P<0.05). Age, pathological type, neck lymph node metastasis complicated with necrosis were the factors of poor prognosis of OS (all P<0.05). N stage and neck lymph node metastasis complicated with necrosis were the factors of poor prognosis of DMFS (both P<0.05).@*Conclusions@#Similar clinical efficacy has been achieved in terms of IMRT for nasopharyngeal carcinoma in non-endemic northwest China compared with that in endemic area. Induction chemotherapy combined with concurrent radiochemotherapy can provide clinical benefits for patients with locally advanced nasopharyngeal carcinoma in non-endemic area.

Comparative study on quality of life between the patients with seasonal and perennial moderate severe persistent allergic rhinitis / 中国耳鼻咽喉头颈外科

OBJECTIVE To explore the differences in quality of life between the patients withseasonal and perennialmoderatesevere persistent allergic rhinitis.METHODS The patients with moderatesevere persistent allergic rhinitis were divided into two groups,seasonal group and perennial group.The distribution of allergens and the quality of life scores of the patients in the two groups were compared.The relationship between the quality of life and the number of allergens in all of the patients were analyzed.The number of allergens in two groups was compared.RESULTS The quality of life scores in seasonal group is higher than that of the perennial group with statistical significance.The patients' quality of life scores was significantly associated with the number of allergens.The seasonal group had a bigger proportion of patients with a variety of allergens.CONCLUSION There was a difference in the quality of life in patients with seasonal and perennial moderatesevere persistent allergic rhinitis.This may be related to the type of allergens,the quantity of allergens,and the patient's tolerance.

The prognostic value of primary tumor volume in non-endemic patients with nasopharynx carcinoma in northwest China / 西安交通大学学报(医学版)

ABSTRACT:Objective To investigate the prognostic value of primary tumor volume in non-endemic patients with nasopharynx carcinoma in northwest China.Methods A total of 393 patients were enrolled in the study and all the patients had been identified with nasopharynx squamous cell carcinoma by biopsy.Overall survival (OS)and distant metastasis free survival (DMFS)were the primary endpoints.The cut-off of tumor volume was identified by ROC curves. Survival results were analyzed by the Kaplan-Meier curve. Independent prognostic factors were identified by COX proportional hazards regression model.Results The 5-year OS and DMFS for all the patients were 74.3% and 73.5%.23 mL was considered as the optimal cut-off value according to the ROC curves,and then the patients were divided into two groups (≤2 3 mL and >2 3 mL ).Patients with tumor volume ≤2 3 mL had significantly better 5-year OS and DMFS than those with tumor volume >2 3 mL (P2 3 mL and N2-3 (P<0.05).Conclusion Primary tumor volume is an independent prognostic factor for survival of nasopharyngeal carcinoma patients in northwest China.

One case of nasal Kaposiform hemangioendothelioma / 临床耳鼻咽喉头颈外科杂志

Female patients, 41 years old, with the left nasal cavity bleeding intermittently and left nasal congestion 20 days as the chief complaint to the hospital. Physical examinationindicated dark red mass was at the front-end of left nasal cavity, which has not smooth surface with blood vessels and hemorrhagic secretions, and back up to the middle turbinate. Sinus enhancement 3D-CT showed soft tissue density can be found in the left nasal cavity,Scan CT value is 37-47 HU, and enhanced and delay is about 69-78 HU. Nasal septum,middle turbinate and inferior turbinate bonewas visible damage. The pathologic biopsy of left nasal cavity lesions results conform to the Kaposiform hemangioendothelioma.

One case of papillary adenocarcinoma located in the back-end of nasal septum / 临床耳鼻咽喉头颈外科杂志

Patients with nasopharyngeal foreign body sensation for 3 years, and had nasal obstruction in the past six months. electric nasopharyngoscopy: a irregular ellipse shape mass occupied in the nasopharynx, the mass surface is not smooth, with erosion ulcer and filthy secretions, the mass had a root in the back-end of nasal septum, and was adjacent to the bilateral round pillow. Sinus CT showed an irregular soft tissue shadow connected to the nasal septum backend in the nasopharynx, the size is about 2.8 cm X 3.5 cm, CT value is about 43 HU. Pathological examination: papillary adenocarcinoma.

One case of huge cyst at the back end of nasal septum / 临床耳鼻咽喉头颈外科杂志

A male of 17 years old complained of bilateral nasal congestion with mouth breathing for half a year. The physical examination showed patency of bilateral nasal cavity. Nasopharyngeal fiberscope revealed a huge spherical smooth reddish mass at the nasopharyngeal posterior wall and the back-end of nasal cavity blocking the entire postnaris and contacting with bilateral tubal tori, the size of which is about 3.5 cm x 2.5 cm. The nasopharyngeal 3D-CT showed a low density cystic mass area in the nasopharynx with smooth edges, and the CT value is approximately 32.4 HU. No exact enhancement was observed. The cystic mass originated from and compressed the back end of nasal septum. A semicircular defect in the leading edge of clivus was observed, and the inferior wall of sphenoid sinus is compressed uplifted upwards. The nasopharyngeal MR showed that the nasopharyngeal lesion presented short T1 and long T2 signals with multiple small wall nodules around. Neither the lesion nor the peripheral nodules can be significantly enhanced by enhancement scan. After a nasal endoscopic surgery, the case was definitely diagnosed as nasal septum back-end huge cyst.

Prognostic role of vascular endothelial growth factor in oral carcinoma: a meta analysis / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To perform a Meta analysis of prognostic cohort studies for evaluating the use of vascular endothelial growth factor (VEGF) as a predictor of survival in patients with oral carcinoma.</p><p><b>METHODS</b>A search of OVIDMEDLINE, EMBASE database and two Chinese database (CNKI and VIP) was conducted using common text words combined with medical subject headings to capture the related cohort studies. Data were collected comparing disease-free and overall survival in patients with high VEGF levels as compared to those with low levels. Studies were pooled and summary hazard ratios (HR) were calculated.</p><p><b>RESULTS</b>14 texts were included in this study. High tissue VEGF levels predicted poor overall survival (HR: 2.95, 95% CI: 2.14-4.08) and disease-free survival (HR: 2.28, 95%CI: 1.61-3.21). Similarly, high VEGF levels predicted poor overall survival (HR: 2.60, 95% CI: 1.82-3.73) and disease-free survival (HR: 2.58, 95% CI: 1.73-3.84) in patients with oral squamous cell carcinoma.</p><p><b>CONCLUSION</b>VEGF may be useful for defining prognosis in oral carcinoma.</p>
