Objective To evaluate the impact of chemotherapy compliance on the therapeutic efficacy of induction chemotherapy plus concurrent chemoradiotherapy versus induction chemotherapy plus radiotherapy alone for patients with locally advanced nasopharyngeal carcinoma (NPC). Methods Based on intention to treat analysis (ITT) for 400 patients, 314 patients were analyzed by per protocol (PP) analysis. The patients were divided into induction chemotherapy plus concurrent chemoradiotherapy group (IC/CCRT, 127 patients) or induction chemotherapy plus radiotherapy group (IC/RT, 187 patients). The patients who completed 2 cycles of induction chemotherapy and at least 2 cycles of concurrent chemotherapy in the IC/CCRT group and the patients who completed 2 cycles of induction chemotherapy in the IC/RT group were analyzed. Radiotherapy was given by two-dimensional technique with γ-ray, X-ray and electron beams. The chemotherapy regimen was FUDR plus carboplatin for induction chemotherapy and carboplatin alone for concurrent chemotherapy. Results The follow-up rate was 96.2%. 295 patients were followed to at 3 years. Based on PP analysis, Grade 3/4 toxicity was found in 23.6% of the patients in IC/CCRT group and 13.4% in the IC/RT group (χ~2 =5,50,P=0.019). No grade 4 toxicity was found in the IC/RT group. The median follow-up time was 3.9 years, and no significant difference was found between the two groups in 3-year overall survival (78.1% : 84.6% ;χ~2 = 0. 61, P =0. 435), disease-free survival (74.3 % : 70.1% ;χ~2= 0. 12, P= 0.731), Iocoregional relapse-free survival (89.7% : 89.5% ; χ~2= 0. 10, P= 0.748), or distant metastasis-free survival (78.9%:76.5% ;χ~2=0.05,P=0.825). Conclusions With more severe toxicities, the IC/CCRT regimen does not improve the overall survival in locally advanced NPC patients compared with the IC/RT regimen.

Objective To compare the efficacy of concurrent chemoradiotherapy versus radiotherapy alone for T3-4 N0-1 M0 and T14 N2-3 M0 nasopharyngeal carcinoma (NPC) after induction chemotherapy.Methods From 2002 to 2005,400 patients with stage Ⅲ and Ⅳa NPC were randomly divided into 2 groups :induction chemotherapy followed by concurrent chemoradiotherapy group (IC/CCRT,201 patients),and induction chemotherapy followed by radiotherapy alone group (IC/RT, 199 patients).Subgroup analysis was conducted for 197 patients with stage T3-4N0-1M0 NPC and 203 with stage T1-4N2-3M0 NPC.Results The follow-up rate were 96.2%, with a median followg-up time of 3.9 years.For T3-4N0-1 M0 NPC patients in IC/CCRT group (104 patients) and IC/RT group (93 patients), the 3-year overall survival, disease-free survival, locoregional recurrence-free survival and distant metastasis-free survival rates were 84.0% and 85.9% (χ2=0.08,P =0.780) ,77.0% and 72.0% (χ2=0.44,P =0.510) ,89.5% and 92.3% (χ2=0.65 ,P = 0.420), and 84.9% and 77.0% (χ2= 1.59, P = 0.210), respectively; For T1-4 N2-3 M0 NPC patients in IC/CCRT group (97 patients) and IC/RT group (106 patients), the corresponding rates were 67.4% and 82.2% (χ2=3.48,P=0.060), 61.5% and 68.0% (χ2= 1.86,P=0.170), 86.2% and 87.0% (χ2=0.57 ,P =0.450) and 66.2% and 75.6% (χ2=2.07 ,P =0.150), respectively.Acute sideeffects were similar except more leucocytopenia in IC/CCRT group than IC/RT group.Conclusions Compared with IC/RT, IC/CCRT dose not improve the overall survival in patients with T3-4N0-1 M0 and T1-4 N2-3 M0 NPC.

Objective:To analyze the feature of cranial nerve involvement in nasopharyngeal carcinoma (NPC) and its relationship with the prognosis.Method:A total of 1892 patients who were diagnosed as NPC in our hospital from January 2002 to December 2003,of which the cranial nerve involvement was 183 (9.6%) patients, were analyzed the effect of cranial nerve involvement on the prognosis.Result:The percentage of cranial nerve involvement was 9.4%. The 5 year overall survival rate was 61.0%,disease free survival rate was 55.3%,local relapse free survival rate was 75.2% and distant metastasis free survival rate was73.4%.Periods of cranial nerve involvement,clinical stage,the diameter of the lymph nodes,involvement of cavernous sinus, and the level of the recovery of cranial nerve involvement were significantly associated with prognosis in univariate analysis(P<0.05).With multivariate analysis,the recovery level of cranial nerve involvement was the independent factor that affected the 5-year overall survival (RR=2.087). The diameter of the lymph nodes and involvement of cavernous sinus were the independent factors that affected the 5-year distant metastasis-free survival(RR=1.954 and 2.136,respectively).Conclusion:Periods of cranial nerve involvement and the level of the recovery of cranial nerve involvement were significantly correlated with prognosis. Involvement of cavernous sinus could increase the rate of distant metastasis.

Objective To investigate effect of famitinib malate on adverse reactions by radiotherapy and chemotherapy in treatment of advanced nasopharyngeal carcinoma and the nursing strategies.Methods From November 2011 to December 2013, 20 cases of advanced nasopharyngeal carcinoma in our hospital were treated with famitinib malate combined with radiotherapy and chemotherapy.During the treatment,we observed the adverse reactions and gave the symptomatic treatment.Results The rates of adverse reactions such as hypertension,renal toxicity,oral mucositis,myelosuppression,gastrointestinal reactions,nasal bleeding, abnormal liver function,and hand-foot skin reaction were 60.0%,70.0%,90.0%,100.0%,85.0%,10.0%,45.0%and 25.0%respectively.After symptomatic treatment,all completed the treatment.Conclusions The incidence rate of adverse reactions of famitinib malate combined with radiotherapy and chemotherapy for treating advanced nasopharyngeal carcinoma is high.Close monitoring and observation during treatment courses can ensure the successful completion of treatment.

Objective To evaluate the diagnostic value of lymph node fine-needle aspiration (FNA)Epstein-Barr virus (EBV)-DNA concentration detection in nasopharyngeal carcinoma (NPC) cervical lymph node metastasis.Methods From August to December 2016,36 cases of NPC and 9 cases of other tumors (not correlated with EBV infection) were enrolled in this study at the Sun Yat-sen University Cancer Center.All patients received magnetic resonance images (MRI),plasma and cervical lymph node FNA EBV-DNA detection.Results The median concentration of EBV-DNA in FNA fluid (1.39 × 105 copies/ml) in cervical lymph node metastasis was significantly higher than that in plasma (2.00 × 103 copies/ml),with a significant difference (x2 =16.723,P =0.004).The diagnosis sensitivity,specificity,accuracy of the lymph node FNA fluid of EBV-DNA were 86.2％ (25/29),71.4％ (10/14) and 81.4％ (35/43) respectively,which were better than those of MRI [72.4％ (21/29),50.0％ (7/14) and 65.1％ (28/43) respectively] and plasma EBV-DNA [55.2％ (16/29),71.4％ (10/14) and 60.5％ (26/43) respectively].The area under the curve (AUC) of level Ⅰ b cervical lymph node metastasis was calculated,and FNA fluid EBV-DNA (AUC =0.688)was better than MRI (AUC =0.583),with a significant difference (Z =2.476,P =0.008).The EBV-DNA concentration in FNA fluid in cervical lymph node metastasis of patients with other tumors (no correlated with EBV infection) was 0 copy/ml.Conclusion FNA fluid EBV-DNA may improve the diagnostic sensitivity of cervical lymph node metastasis in nasopharyngeal carcinoma,and help to explore the clinical target volume neck nodes at level Ⅰ b cervical lymph node in radiotherapy.
