Purpose:To compare chemoradiotherapy against radiotherapy alone in the treatment of locoregionally advanced nasopharyngeal carcinoma.Methods:From September 1995 to July 1997,eighty-six patients with histologically proven NPC who were staged according to the Fuzhou stage classification to be N 2-3 were entered. Eighty-four patients were evaluable for tumor response and survival. The patients were randomized to receive two cycles of cisplatin (DDP) 20 mg/m 2 on Days 1-3,fluorouracil (5-Fu) 500 mg/m 2 on Days 1-3,before radical radiotherapy (RT),and three cycles of postradiotherapy chemotherapy (39 patients) or radiotherapy alone (45 patients). For chemoradiotherapy (CT-RT) group,the second cycle was given on Day 14 and the radiotherapy was given on Day 27. All patients received radical radiotherapy to the nasopharynx and neck. Radiation therapy consisted of delivering 65.1-70.3 Gy in 35-37 fractions of 1.85-1.9 Gy each over 7-7.5 weeks to the primary site with external beam 60 Co in both groups. The lymph nodes of the neck were given 56.6-65.5 Gy in 7-7.5 weeks. Boost radiotherapy was given to any residual disease. The rates of radiotherapy for boosting primary site or residual lymph nodes were not significantly different in the two arms. Results:The median follow up was 5.04 years. The 5-year actuarial survival rate (ASR) was 72.3% in CT-RT arm and 58.4% in RT arm ( P =0.154). The 5-year disease free survival rate (DFS) was 59.9% in CT-RT arm and 47.7% in RT arm ( P =0.207). The 5-year free from local failure rate (FLF) in nasopharynx was 89.5% in CT-RT arm and 81.4% in RT arm respectively ( P =0.151). The 5-year FLF in neck was 88.3% in CT-RT arm and 75.2% in RT arm respectively ( P =0.134). The 5-year free from distant metastasis rate (FDM) was 76.3% in CT-RT arm and 60.3% in RT arm ( P =0.181). The median time to first distant metastasis was 1.08 years in CT-RT arm and 0.88 year in RT arm. Although the differences did not reach statistical significance,there was some benefit from adjunctive chemotherapy to radiotherapy in the treatment of locoregionally advanced nasopharyngeal carcinoma. Toxicities in CT-RT arm were mainly myelosuppression and nausea and vomiting. There was no significant difference in the incidence and severity of acute mucositis between the two arms during radiotherapy. There was no treatment-related death. Conclusions:This prospective randomized trial demonstrated some benefit in DFS,FLF,FDM from adjunctive chemotherapy to radiotherapy in the treatment of locoregionally advanced nasopharyngeal carcinoma. But the differences were not significant. The chemoradiotherapy increased neither the incidence and severity of acute mucositis nor the late reaction.

Background and purpose: With the development of therapy equipments and technology, the treatment for nasopharyngeal carcinoma(NPC) has entered into the era of precision radiotherapy, and setup errors have become a very important factor affecting treatment effects. The purpose of this study was to analyze the set-up errors detected by the kilovoltage cone beam CT(EPID) and the megavoltage electronic portal imaging device(CBCT) using 2 kinds of different immobilization techniques (pillow+head neck shoulder mask and vacuum bag+head neck shoulder mask) for NPC patients. Methods:A total number of 40 NPC patients were randomly assigned into 2 groups (pillow+head neck shoulder mask group and vacuum bag+neck shoulder mask group). Then each group was further divided into CBCT scan group and EPID group for veriifcation before treatment delivery. We matched the EPID images with the DRRs and acquired the set-up errors in x, y, z axis. Setup errors of CBCT were calculated according to its matched and planned CT images in left-right (x), superior-inferior (y) and anterior-posterior (z) directions. Paired t-test was used to evaluate the differences. Results:In the pillow+head neck shoulder mask group, the set-up errors of CBCT in the x, y, z axis were x (0.67±2.01)mm, y (0.51±1.71)mm and z (0.57±2.04)mm, respectively. The errors of EPID were x (0.69±2.19)mm, y (0.54±2.03)mm and z (0.61±2.11)mm. In the vacuum bag+head neck shoulder mask group, the set-up errors of CBCT in the x, y, z axis were x (0.42±1.81)mm, y (0.33±1.55)mm and z (0.50±1.75)mm, respectively. The errors of EPID were x (0.44±1.87)mm, y (0.43±1.70)mm and z (0.54±1.77)mm. The vacuum bag+head neck shoulder mask ifxed technique was more accurate when compared to the pillow + head neck shoulder mask ifxation method (P<0.05). Conclusion:CBCT and EPID were similar in detecting set-up errors for the NPC patients. However, the vacuum bag+neck shoulder mask ifxed technique was more accurate when compared to the pillow+head neck shoulder mask ifxation method.

ObjectiveTo evaluate the efficacy and toxicity of gemcitabine plus cisplatin (GP)chemotherapy combined with intensity-modulated radiation therapy (IMRT)in locoregionally advanced nasopharyngeal carcinoma (NPC).Methods71 patients (Stage Ⅲ:41,Stage ⅣA:30) with locoregionally advanced NPC were entered this study.Neoadjuvant chemotherapy was consisted of cisplatin 25 mg/m2 intravenously on d1-3 and gemcitabine 1000 mg/m2 in 30 minutes intravenous infusion on days 1 and 8,every 3 weeks for 2 cycles.Adjuvant chemotherapy consisted of 2 cycles of the same GP regimen was given at 28 days after the end of radiotherapy.The prescription doses was 66.0-70.4 Gy to the gross tumor volume,66 Gy to positive neck nodes,60 Gy to the high-risk clinical target volume,54 Gy to the low-risk clinical target volume.ResultsThe overall response rate to neoadjuvant chemotherapy was 91.2％,acute toxicity was mainly grade 1-2 myleosuppression.All patients completed IMRT.The median follow-up duration was 38 months.The 3-year nasopharyngeal local control,regional control,distant metastasis-free survival rate and overall survival rate were 93％,99％,91％,90％,respectively.Severe late toxicities included grade 3 trismus in 1 patient,grade 3 hearing impairment in 2 patients and cranial nerve palsy in 2 patients,respectively.No grade 4 late toxicities were observed.Conclusions The combination of GP chemotherapy and IMRT for locoregionally advanced nasopharyngeal carcinoma is well-tolerated,convenient,effective,and warrants further studies of more proper cycles of GP regimen.

Objective To study the effect of different fraction interval with same total radiation dose on tumor growth delay and survival in C57BL mice implanted with lewis lung cancer,and to determine whether prolonged fraction interval will decrease the tumor response to radiation. Methods Forty-eight mice were implanted with lewis lung cancer in the back legs.When the diameter of transplanted tumor reached 0.8 to 1 cm,the mice were randomized into 6 groups:normal control group,single fraction of 18 Gy group,18 Gy in 2 fractions of 9 Gy at 30 min interval group,18 Gy in 7 fractions of 2.57 Gy at 5 min inter val group,18 Gy in 2 fractions of 9 Gy at 60 min interval group and 18 Gy in 7 fractions of 2.57 Gy at 10 rain interval group.The maximal and minimal diameters of the tumor were measured and record every other day to study the tumor growth tendency,the tumor growth delay and the mice survival time. Results The tumor growth delay of groups at prolonged fraction interval was shorter than the group with single fraction of 18 Gy (P < 0.05).The tumor growth delay of groups at fraction interval of 30 rain was longer than that of groups at interval of 60 rain (P < 0.05).There was no significant difference of the tumor growth delay be tween the groups with same delivery time (P >0.05).The mice survival time of the groups with prolonged fraction interval was shortened when omparing to the group with single fraction of 18 Gy.While the difference was not significant between the groups at fraction interval of 30 min and 60 min. Conclusions The pro longed fraction interval but same total radiation dose shortens the tumor growth delay and survival time in the mice implanted with Lewis lung cancer.The longer fraction interval impairs the tumor control more signifi candy.However the difference of the effect on mice survival time is not significant between the groups at fraction interval of 30 min and 60 min.
