The selection of irradiation volume for neck lymph node-negative nasopharyngeal carcinoma: the results based on a Meta-analysis study / 中华放射医学与防护杂志

Objective To study the appropriate neck irradiation volume for neck lymph nodenegative nasopharyngeal carcinoma patients by Meta-analysis.Methods The related references published from Jan 1990 to Jun 2013 were searched in Pubmed,Embase,Cochrane and Wangfang Databases.The qualified references for enrollment criteria were screened and the relative data were collected.The OR (Odds ratio) value by fixed effect model was used to evaluate the data for patients who received radiotherapy between the upper neck and whole neck irradiation.The endpoints including 5-year neck local control rate (LCR),neck-in-irradiation LCR,and neck-outsides-irradiation LCR.Results Five qualified references were screened and belonged to respective research.There enrolled 1 333 patients,including 970 patients who received the upper neck irradiation and 363 patients who received the whole neck irradiation,respectively.The forest plots revealed that there were no significant differences for 5-year neck LCR,neckin-irradiation LCR,and neck-outsides-irradiation LCR for patients received radiotherapy between the upper neck and whole neck irradiation.These OR values were 0.89 (95％ CI:0.41-1.94),1.29 (95％ CI:0.58-2.88) and 0.42 (95％ CI:0.07-2.36),respectively.Conclusions The Meta-analysis results suggest that irradiation to the upper neck for neck lymph node-negative nasopharyngeal carcinoma can be appropriate.

Detection and analysis of clinical risk factors for short-term recurrence of oral squamous cell carcinoma / 重庆医科大学学报

Objective:To detect and analyze the clinical risk factors about short-term recurrence of oral squamous cell carcinoma.Methods:A retrospectively comparative research on a total 106 patients with oral squamous cell carcinoma who were divided into two groups according to short-term recurrence and no short-term recurrence,was carried out.All patients had been followed up for one year.The main parameters such as sex,age,tumor region,clinical and pathologic character,TNM stage,surgical management,lymph node metastasis were analyzed statistically,and the results were analyzed by x 2 analysis.Results:①The short-term recurrence rate of oral squamous cell carcinoma was 18.87%.②Age (below 40 year-old),surgical management and neck lymph node metastasis were clinical risk factors related to short-term recurrence of oral squamous cell carcinoma except tumor region,clinical and pathologic character and TNM stage.There was significant difference between two groups( P
