Results of a prospective randomized trial comparing neoadjuvant chemotherapy plus radiotherapy with radiotherapy alone in patients with locoregionally advanced nasopharyngeal carcinoma.

PURPOSE: A prospective randomized trial was performed to evaluate the contribution of neoadjuvant chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma. PATIENTS AND METHODS: Patients with locoregionally advanced nasopharyngeal carcinoma were treated either with radiotherapy alone (RT group) or neoadjuvant chemotherapy plus radiotherapy (CT/RT group). Neoadjuvant chemotherapy consisting of two to three cycles of cisplatin (100 mg/m(2), day 1), bleomycin (10 mg/m(2), days 1 and 5), and fluorouracil (5-FU; 800 mg/m(2), days 1 through 5, continuous infusion) followed by radiotherapy was given to the CT/RT group. All patients were treated in a uniform fashion by definitive-intent radiation therapy in both groups. RESULTS: Between July 1993 and July 1994, 456 patients were entered onto the study, with 228 patients randomized to each treatment arm, and 449 patients (225 in the RT group and 224 in the CT/RT group) were assessable. All 456 patients were included in survival analysis according to the intent-to-treat principle. The 5-year overall survival (OS) rates were 63% for the CT/RT group and 56% for the RT group (P =.11). The median relapse-free survival (RFS) time was 50 months for the RT group and not reached for the CT/RT group. The 5-year RFS rate was 49% for the RT group versus 59% for the CT/RT group (P =.05). The 5-year freedom from local recurrence rate was 82% for the CT/RT group and 74% for the RT group (P =.04). There was no significant difference in freedom from distant metastasis between the two treatment groups (CT/RT group, 79%; RT group, 75%; P =.40). CONCLUSION: This randomized study failed to demonstrate any significant survival benefit with the addition of neoadjuvant chemotherapy for patients with locoregionally advanced nasopharyngeal carcinoma. Therefore, neoadjuvant chemotherapy for nasopharyngeal carcinoma should not be used outside of the context of a clinical trial.

局部晚期鼻咽癌放疗与化疗联合治疗进展

鼻咽癌(NPC)是常见的头颈部恶性肿瘤之一,放疗是NPC的主要治疗方法。化疗策略(诱导、同期、辅助)在放疗中的综合应用提高了局部晚期NPC的疗效。目前同期放化疗联合辅助或诱导化疗已被推荐为局部晚期NPC标准治疗方法。然而,标准治疗仍有许多不足之处,诱导及辅助化疗仍有许多争议,建立更加理想及个体化的局部晚期NPC放化疗方案仍是未来研究的方向。     

Preliminary results of a phase III randomized study comparing chemotherapy neoadjuvantly or concurrently with radiotherapy for locoregionally advanced nasopharyngeal carcinoma

The current study was conducted to compare neoadjuvant chemotherapy (NACT) with concurrent chemotherapy for efficacy, toxicities and compliance of locoregionally advanced nasopharyngeal carcinoma (NPC). Eligible patients were randomized to NACT + radiotherapy (RT) + adjuvant chemotherapy (AC) arm or concurrent chemoradiotherapy(CCRT) + AC arm. Two arms received same conventional RT at a planned dose of 70 Gy. Neoadjuvant chemotherapy comprised cisplatin 90 mg/m² (30 mg/m²/day) and 5-fluorouracil 1,500 mg/m² (500 mg/m²/day) over 3 days for two 21-day cycles. The same regimen at equal dosage was administered on the 1st and 22nd days of the radiotherapy as concurrent chemotherapy. Four cycles of the same chemotherapy regimen were given to both two arms as AC. A total of 338 NPC patients were recruited. 170 patients were randomized to NACT arm and 168 patients to CCRT arm. The median duration of follow-up was 38 months. The 3-year OS and DFS rates were 95.9 versus 94.5% (P = 0.54) and 78.5 versus 82.5% (P = 0.16), respectively, in NACT and CCRT arms. An unplanned subgroup analysis according to the N-classification suggested that CCRT improves MFS in patients with N0-1 disease (80.1 vs. 94.9%, P = 0.034). Among the acute toxicities observed, the rates of grade 3/4 mucositis (52.4 vs. 35.9% P = 0.023) and vomiting (13.7 vs. 4.7% P = 0.000) were significantly higher in CCRT arm. Our preliminary results only showed an advantage of CCRT over NACT in NPC patients with limited N disease in MFS. More acute toxicities were observed in CCRT arm and a trend of better tolerance was observed in NACT arm.     

西妥昔单抗联合放化疗治疗进展期鼻咽癌的临床研究

背景与目的:最新研究报道,西妥昔单克隆抗体(单抗)联合放疗较单纯放疗降低了局部晚期头颈部鳞癌患者的死亡率.为探讨西妥昔单抗在鼻咽癌中的作用,本研究初步观察西妥昔单抗联合放化疗治疗晚期鼻咽癌患者的不良反应及近期疗效.方法:取我院收治的晚期鼻咽癌患者12例.西妥昔单抗与放疗或化疗或同步放化疗同时使用,用法:西妥昔单抗第1周初始剂量为400 mg/m2,以后每周维持剂量为250 mg/m2,共8周.初诊或局部复发鼻咽癌患者均采用调强放疗技术,给予鼻咽部GTV处方剂量D6 975 cGy/31次,6.2周完成.对鼻咽癌转移灶姑息放疗,予转移灶外照射D3 000 cGy/10次,2周完成.结果:2例放疗后多脏器转移患者因病情进展而停用西妥昔单抗,2例初诊鼻咽癌因西妥昔单抗引起的Ⅲ级舌黏膜反应而停药,2例因Ⅲ级皮疹延迟用药1周,余6例顺利完成治疗计划.西妥昔单抗主要不良反应为皮疹、甲沟炎、黏膜反应、疲乏等.10例鼻咽部调强放疗同时使用西妥昔单抗的患者中,5例出现Ⅲ级口咽黏膜反应,其中4例同时出现Ⅲ级舌黏膜反应.全组完全缓解7例(58.3%),部分缓解3例(25.0%),疾病稳定2例(16.7%).中位随访14个月,2例死亡,10例存活且肿瘤无进展.结论:西妥昔单抗联合放化疗治疗晚期鼻咽癌的安全有效,但联合鼻咽部调强放疗时少部分患者出现较重的舌黏膜反应,影响治疗计划的顺利进行,需进行进一步临床试验研究.

Prognostic features and treatment outcome in locoregionally advanced nasopharyngeal carcinoma following concurrent chemotherapy and radiotherapy

Purpose: Concurrent chemotherapy and radiotherapy (CCRT) are effective in treatment of locoregionally advanced nasopharyngeal carcinoma (NPC). However, the prognostic factors after CCRT have not been evaluated. We therefore attempt to evaluate factors that influence treatment outcomes following CCRT.Methods and Materials: Seventy-four (5 in stage III and 69 in stage IV) patients with locoregionally advanced NPC were treated with CCRT. Radiotherapy was delivered either at 2 Gray (Gy) per fraction per day up to 70 Gy or 1.2 Gy, 2 fractions per day, up to 74.4 Gy. Concurrent chemotherapy consisted of cisplatin and 5-fluorouracil. Cox proportional-hazards model was used to analyze the prognostic factors which included age, gender, pathologic type, T, N, lactate dehydrogenase (LDH), and infiltration of the clivus.Results: The primary tumor control rate at 3 years was 96.7% (95% confidence interval [CI]: 92.5–100), distant metastasis–free survival 81.1% (95% CI: 70.6–91.6), disease-free survival 77.0% (95% CI: 65.3–88.7), and overall survival 79.8% (95% CI: 69.2–90.4) with a median follow-up interval of 29 months (range 15–74 months). Cox proportional-hazards model revealed that infiltration of the clivus and serum level of LDH before treatment were the most two important factors that predict distant metastases. Infiltration of the clivus and the serum LDH level greater than 410 U/L were strongly associated with distant metastasis–free survival (p = 0.0004 and p = 0.0002, respectively). When these two risk factors were considered together, no distant metastasis was observed in 40 patients with both intact clivus and LDH ≦410 U/L. On the contrary, 13 of the remaining 34 patients with at least one risk factor developed distant metastasis (p = 0.0001).Conclusion: Our study demonstrates that CCRT can improve the primary tumor control of 96.7% and disease-free survival of 77.0% at 3-year follow-up. Distant metastasis, however, is the major cause of failure. Infiltration of the clivus by the tumor and LDH greater than 410 U/L are the two independent and useful prognostic factors in patients with locoregionally advanced NPC who were treated with CCRT. Good- and poor-risk patients can be distinguished by virtue of their having both conditions.     

h-R3联合放疗治疗局部晚期鼻咽癌的Ⅱ期临床研究

背景与目的:目前临床应用的抗表皮生长因子受体(epidermal growth factor receptor,EGFR)的单克隆抗体易产生人抗鼠抗体反应,影响治疗效果.本研究评估人源化的抗EGFR单克隆抗体h-R3联合放疗对局部晚期鼻咽癌的近、远期疗效及毒性反应.方法:将免疫组化证实有EGFR中、强度表达的Ⅲ～Ⅳb期(UICC 1997)鼻咽癌初诊患者随机分为单纯放疗组(单放组)和放疗联合h-R3组(联合组),两组的放疗剂量和技术基本相同,联合组在放疗期间每周一次静脉滴注h-R3 100 mg.用WHO标准评价两组的近期疗效,用Kaplan-Meier法估计两组的生存率.结果:本研究共纳入35例,单放组和联合组分别为17例和18例,其中联合组有1例于治疗中途退组.联合组于治疗结束时、治疗后5周及治疗后17周时的总CR率分别为72.2%、83.3%和83.3%,而单放组分别为35.3%、41.2%和47.1%(P＜0.05).中位随访时间31.9个月(4.2～40.7个月),单放组的3年局部区域控制率、无远处转移生存率分别为和总生存率93.8%、100%和88.2%,联合组分别为100%、88.2%和94.4%,两组间的差异无统计学意义(P＞0.05).联合组除1例出现Ⅱ级呕吐外,均无任何药物不良反应发生,两组的急性放射反应差异也无统计学意义(P＞0.05).结论:h-R3是一种安全性良好的药物,有助于增强局部晚期鼻咽癌的放射灭瘤效应,但对远期疗效似乎无明显影响.     

诱导化疗联合同期放化疗与同期放化疗治疗局部晚期鼻咽癌的对比研究

  目的  比较诱导化疗联合同期放化疗与同期放化疗治疗局部晚期鼻咽癌(LA-NPC)的临床结果及探讨预后因素。  方法  分析2005年1月至2006年12月本院收治的433例无转移LA-NPC患者的临床资料, 按是否行诱导化疗分为诱导化疗联合同期放化疗组(A组)209例与同期放化疗组(B组)224例。采用Kaplan-Meier法进行生存分析, 差异比较采用Log-Rank法双侧检验, 预后因素分析采用Cox模型。  结果  A组、B组的3年总生存率(OS)、无局部区域复发生存率(LR-FFS)、无远处转移生存率(D-FFS)、无瘤生存率(FFS)分别为87% vs. 88%、95% vs. 95%、85% vs. 85%、81% vs. 81%;A组、B组的5年OS、LR-FFS、D-FFS、FFS分别为80% vs. 82%(P=0.503), 95% vs. 93%(P=0.673), 82% vs. 82%(P=0.992), 78% vs. 77%(P=0.851)。两组生存差异无统计学意义, 对于Ⅲ期鼻咽癌, A组FFS优于B组(P=0.075)。多因素分析显示老年、临床分期晚、颅神经侵犯、贫血、N分期晚为OS、D-FFS的独立不良预后因素。  结论  与同期放化疗相比, 诱导化疗联合同期放化疗未提高LA-NPC的OS、LR-FFS、D-FFS及FFS, 但具有改善Ⅲ期鼻咽癌FFS的趋势。诱导化疗联合同期放化疗不是鼻咽癌的必选治疗模式。      

同步放化疗对中晚期鼻咽癌患者听觉功能的影响

目的:评价和比较同步放化疗与序贯治疗对中晚期鼻咽癌听觉功能的影响。方法:44例中晚期鼻咽癌患者随机分入同步治疗组和序贯治疗组。两组患者均在放疗前、放疗开始后1月和放疗结束后(1个月、3个月、6个月、12个月)检查纯音听阈和鼓室导抗图。结果:同步治疗组患者的听力损害大于序贯治疗组(P<0.05)。放疗后1个月同步治疗组患者的语频(0.5~4.0kHz)和高频(8kHz)平均骨导听阈较治疗前分别提高7.2dB和25.5dB,而序贯治疗组分别提高了15.2dB和36.8dB,两组差异有统计学意义(P<0.05)。结论:同步治疗组患者的听力损害较序贯治疗组发生早、发生率高、程度重。
