Treatment outcomes and late toxicities of 869 patients with nasopharyngeal carcinoma treated with definitive intensity modulated radiation therapy: new insight into the value of total dose of cisplatin and radiation boost

This study was to report the long-term outcomes and toxicities of nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). From 2009 to 2010, 869 non-metastatic NPC patients treated with IMRT were retrospectively enrolled. With a median follow-up of 54.3 months, the 5-year estimated local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), distant metastasis-free survival (DMFS), disease-free survival (DFS) and overall survival (OS) were 89.7%, 94.5%, 85.6%, 76.3%, 84.0%, respectively. In locally advanced NPC, gender, T, N, total dose of cisplatin more than 300 mg/m² and radiation boost were independent prognostic factors for DMFS and DFS. Age, T, N and total dose of cisplatin were independent prognostic factors for OS. Radiation boost was an adverse factor for LRFS, RRFS, DMFS and DFS. Concurrent chemotherapy was not an independent prognostic factor for survival, despite marginally significant for DMFS in univariate analysis. Concurrent chemotherapy increased xerostomia and trismus, while higher total dose of cisplatin increased xerostomia and otologic toxicities. In conclusion, IMRT provided satisfactory long-term outcome for NPC, with acceptable late toxicities. Total dose of cisplatin was a prognostic factor for distant metastasis and overall survival. The role of concurrent chemotherapy and radiation boost in the setting of IMRT warrants further investigation.

Prognostic factors in patients with nasopharyngeal carcinoma treated in Hospital Kuala Lumpur

Background: Nasopharyngeal carcinoma is the third most common cancer among men in Peninsular Malaysia.However, no information is available about the prognostic factors. The objective of this study was to identifyfactors with an influence on outcome in patients treated in Hospital Kuala Lumpur. Methods: A total of 159patients with non-metastatic nasopharyngeal carcinoma treated during 2002-2003 in Hospital Kuala Lumpurwere included in this study. All received radiotherapy. Fifty three patients were treated with radiotherapy alone,while 106 patients received combination chemotherapy. Overall survival and local recurrence-free survival wereanalyzed using the Kaplan-Meier method and univariate analysis was performed using the log-rank test. Results:This study found out that 5-year overall survival and 5-year local recurrence-free survival rates were 58.6% and54.2% respectively. The stage specific 5-year overall survival rates were: Stage I, 100%; Stage II; 93.3%, StageIII, 62.7%; Stage IVA, 42.2%; and Stage IVB, 40.6%. On univariate analysis, gender (p<0.05), T-classification(p< 0.001), N-classification (p<0.05), stage (p<0.05) and cranial nerve involvement (p< 0.001) were found to besignificant prognostic factors for 5-year overall survival, while gender (p<0.05) and N-classification (p<0.05)were significant prognostic factors for 5-year local recurrence-free survival. Conclusion: The overall survivalrate of patients for this study was low. The patient factor that significantly affected 5-year overall survival wasgender, while disease factors were stage, T-classification, N-classification and cranial nerve involvement.     

基于IMRT的Ⅱ期鼻咽癌同期放化疗与单纯放疗远期疗效比较

目的 评价以IMRT为基础的不同治疗模式对Ⅱ期鼻咽癌患者预后的影响。方法 回顾分析123例Ⅱ期鼻咽癌患者的临床资料,其中单纯放疗81例,同期放化疗42例。Kaplan-Meier计算生存率并Logrank检验。结果 全组5年OS、LRFS、DMFS、PFS分别为96.7%、94.7%、93.1%、87.8%。单纯放疗组与同期放化疗组相比,5年OS (98.7%:92.9%,P=0.569)、LRFS (94.8%:94.5%,P=0.770)、DMFS (94.5%:90.2%,P=0.408)、PFS (90.6%:82.2%,P=0.340)均无明显差异。T₂N₁期患者两组5年各项生存率仍无明显差异(P=0.929、0.967、0.917、0.492)。急性不良反应方面同期放化疗组中性粒细胞减少、白细胞减少、血红蛋白减少和放射性黏膜反应发生率明显升高(P=0.000、0.000、0.012、0.010),而两组晚期不良反应发生率相近(P=0.823、0.622、0.113)。结论 对Ⅱ期患者同期化疗的加入并未改善患者预后,但急性不良反应明显增加。     

非转移性T4期鼻咽癌的预后影响因素分析

目的探讨非转移性ⅣA期鼻咽癌的预后影响因子。方法初治的T4N0~3M0 (UICC 1997版分期)鼻咽癌患者145例纳入临床研究,分析患者的复发、转移、生存情况及预后影响因素。结果145例患者的5年OS、CCS、PFS、DLRFS、DMFS分别为59.2％、61.3％、53.0％、71.6％、62.6％。多因素分析显示：颈动脉鞘区受侵是影响DLRFS、DMFS的不良预后因素,UICC N分期是影响DLRFS、 DMFS的独立预后因素;颈动脉鞘区受侵是影响CCS的独立不良预后因素,年龄、颈部照射剂量、UICC N分期是影响CCS的独立预后因素。单因素分析显示: 颈动脉鞘区受侵、UICC N分期是影响CCS、PFS的预后因素,同期化疗或放疗联合化疗虽提示有提高DMFS及提高CCS的趋势,但差异无统计学意义（P＞0.05）。结论颈动脉鞘区受侵、UICC N分期是影响非转移性T4期鼻咽癌的重要预后因子。     

Prognostic value of magnetic resonance imaging-detected cranial nerve invasion in nasopharyngeal carcinoma

Background:

We previously reported that magnetic resonance imaging evidence of cranial nerve invasion was an unfavourable prognostic factor in nasopharyngeal carcinoma. However, the prognostic value of this evidence in nasopharyngeal carcinoma treated with intensity-modulated radiotherapy remains unknown.

Methods:

We retrospectively analysed 749 nasopharyngeal carcinoma patients who underwent intensity-modulated radiotherapy.

Results:

Cranial nerve invasion was observed in 299 (39.9%) patients with T3–4 disease. In T3–4 nasopharyngeal carcinoma, magnetic resonance imaging-detected cranial nerve invasion was associated with inferior 5-year overall survival, distant metastasis-free survival, and locoregional relapse-free survival (P=0.002, 0.003, and 0.012, respectively). Multivariate analyses confirmed that cranial nerve invasion was an independent prognostic factor for distant metastasis-free survival (hazard ratio, 1.927; P=0.019) and locoregional relapse-free survival (hazard ratio, 2.605; P=0.032). Furthermore, the receiver-operating characteristic curves verified that the predictive validity of T classifications was significantly improved when combined with magnetic resonance imaging-detected cranial nerve invasion in terms of death, distant metastasis, and locoregional recurrence (P=0.015, 0.021 and 0.008, respectively).

Conclusions:

Magnetic resonance imaging-detected cranial nerve invasion is an independent adverse prognostic factor in nasopharyngeal carcinoma treated with intensity-modulated radiotherapy.     

Ⅱ期和Ⅲ期直肠癌根治术后卡培他滨同期放化疗疗效及失败原因分析

目的 分析Ⅱ、Ⅲ期直肠癌根治术后卡培他滨同期放化疗Ⅱ期临床研究结果.方法 2005-2007年间共131例病理诊断明确的Ⅱ、Ⅲ期直肠癌患者纳入研究,所有患者均接受根治术后同期化放疗和辅助化疗.治疗方案为全盆腔放疗50 Gy分25次,放疗期间同期应用卡培他滨1600mg/m2,每天分2次服用,连用2周停l周.结果 同期放化疗期间3+4级不良反应发生率为28.2％.随访率为93.9％,3年总生存率、无局部区域复发生存率和无远处转移生存率分别为85.1％、96.7％和79.5％.共31例出现复发,包括5例局部区域复发和28例远处转移.单因素分析提示病理低分化或中低分化、未接受辅助化疗、ⅢC期和淋巴结阳性率＞30％是影响总生存的因素(x2=15.49、15.85、8.80和9.76,P=0.000、0.000、0.011和0.002),ⅢC期、未接受辅助化疗和淋巴结阳性率＞30％是影响无远处转移生存的因素(x2 =6.51、11.57和9.70,P=0.034、0.001和0.002).但未接受辅助化疗者中病理为低分化或T4期的患者更多(x2 =7.20、6.48,P=0.027、0.039).结论 Ⅱ、Ⅲ期直肠癌根治术及卡培他滨同期放化疗后局部区域控制率高,远处转移是主要失败原因.     

Re-irradiation of nasopharyngeal carcinoma with intensity-modulated radiotherapy.

BACKGROUND AND PURPOSE: To evaluate the treatment outcome in patients with locally recurrent nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). MATERIALS AND METHODS: Between October 2001 and May 2004, 31 patients with locally recurrent NPC received re-irradiation using IMRT. The rT classification distribution was 3 for rT1, 5 for rT2, 9 for rT3, and 14 for r T4. Median time from first course of radiotherapy to re-irradiation was 51 months. IMRT was performed using step-and-shoot method with nine 4-6 MV photon fields and median prescribed dose was 54 Gy (range: 50-60 Gy). Additional treatments included cisplatin-based induction chemotherapy in 68% and radiosurgery boost with a single dose which ranged from 8.5 to 12.5 Gy in 32%. Median follow-up time was 11 months. RESULTS: After re irradiation, 58% of patients had complete regression of primary tumor. One-year loco-regional progression-free, distant metastasis-free and overall survival rates were 56, 90, and 63%, respectively. Significantly better 1-year local progression-free rate was observed in rT1-3 than r T4 tumor (100 vs. 35%). Grade 3 late toxicities, mostly ototoxicity/cranial neuropathy, occurred in six patients (19%). One-year actuarial rates of late toxicities were 70% for all grades and 25% for Grade 3. CONCLUSION: Our preliminary results showed that good control of rT1-3 NPC can be achieved using IMRT with a dose between 50 and 60 Gy, whereas the outcome for r T4 tumor remained poor. Late toxicities were common but incidence of severe toxicities was relatively low.

Phase III study comparing standard radiotherapy with or without weekly oxaliplatin in treatment of locoregionally advanced nasopharyngeal carcinoma: preliminary results.

PURPOSE: A prospective, randomized, phase III study was performed to evaluate the feasibility and efficacy of concurrent weekly oxaliplatin with radiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS: From January 2001 to January 2003, 115 patients with locoregionally advanced NPC were randomly assigned to either radiotherapy (RT) alone (56 patients) or concurrent chemoradiotherapy (CCRT; 59 patients). All patient characteristics were well balanced in both arms. CCRT with oxaliplatin 70 mg/m2 weekly was administered for six doses from the first day of RT. RESULTS: All patients were eligible for toxicity and response analysis. Compliance with the protocol treatment was excellent, with 97% of patients completing all planned doses of oxaliplatin, and a lack of high-grade toxicity was observed. After a median follow-up time of 24 months, there was a significant difference in overall survival (OS), relapse-free survival (RFS), and metastasis-free survival (MFS) in favor of the CCRT arm. The 2-year OS rates were 100% for the CCRT arm and 77% for the RT arm (P = .01). The 2-year MFS rates were 92% for the CCRT arm and 80% for the RT arm (P = .02). The 2-year RFS rates were 96% for the CCRT arm and 83% for the RT arm (P = .02). CONCLUSION: CCRT with weekly oxaliplatin is feasible and improves OS, MFS, and RFS rates in patients with locoregionally advanced NPC. Therefore, further randomized trials including oxaliplatin are warranted.
