目的 评价早期鼻咽癌各亚组根治性调强放疗(IMRT)的远期疗效和副反应.方法 回顾分析2001-2008年在本中心初诊接受IMRT的198例按UICC/AJCC2002分期的早期鼻咽癌的5年生存率、治疗失败因素和急性副反应.Kaplan-Meier法计算生存率并Logrank检验.结果 中位随访时间为50.9个月(12~104个月),随访率为96%,随访满1、3、5年者分别为198、139、72例.全组病例5年的肿瘤相关生存率、鼻咽局部无复发生存率及无远处转移生存率分别为97.3%、97.7%及97.8%.T1、T2期患者5年鼻咽局部无复发生存率分别为100%、96.7%(x2=2.24,P=0.135).T1N0、T2N0、T1N1和T2N1期的5年无远处转移生存率分别为100%、98.8%、100%和93.8%(x2=2.35,P=0.125).全组治疗5年总失败率仪为6.1%(12例)且全部为Ⅱb期患者.急性副反应主要是1、2级黏膜炎及咽喉炎,未发现放射性脑、脊髓病和脑神经损伤的晚期副反应.结论 IMRT早期鼻咽癌能取得较好疗效且治疗副反应轻微;但T2b和T2bN1期患者有相对较高的局部复发和远处转移趋势,也许对这些患者放化疗能进一步获益.Abstract: Objective To evaluate the outcomes and toxicities of early stage nasopharyngeal carcinoma(NPC)patients treated with intensity-modulated radiotherapy(IMRT)alone. Methods From February 2001 to January 2008, 198 early stage NPC patients according to AJCC/UICC 2002 staging system were treated by radical radiotherapy with IMRT technique in our institute, the clinical data were analyzed retrospectively. Results The 5-year disease-specific survival, local recurrence-free survival(LRFS)and distant metastasis-free survival(DMFS)were 97.3%, 97.7% and 97. 8% respectively. The 5-year LRFS for T1, T2 patients were 100%, 96. 7%(x2 = 2. 24 ,P = 0. 135)respectively. The 5-year DMFS for T1 N0,T2N0, T1N1, and T2N1 patients were 100%, 98. 8%, 100% and 93. 8%(x2= 2. 35, P= 0. 125)respectively. Grade 1 and 2 mucositis and pharyngitis were most common acute toxicities. Radiation encephalopathy and cranial nerve injury were not observed in all patients. Conclusions IMRT alone for early stage NPC patients can produce satisfactory results and acceptable treatment-relative toxicities. Patients with T2b and T2bN1 had a relatively higher incidence of local recurrence and distant metastasis, which suggested that combination of IMRT and chemotherapy may improve clinical results in those patients. 相似文献

Nasopharyngeal carcinoma treated by radical radiotherapy alone: Ten-year experience of a single institution 总被引:21,自引:0,他引:21
Yi JL Gao L Huang XD Li SY Luo JW Cai WM Xiao JP Xu GZ 《International journal of radiation oncology, biology, physics》2006,65(1):161-168
PURPOSE: To report on our experience in the treatment of nasopharyngeal carcinoma (NPC) by radical radiotherapy alone in our institution during the last decade. METHODS AND MATERIALS: From January 1990 to May 1999, 905 NPC patients were treated and were studied retrospectively. Radical radiotherapy was given to this cohort by conventional technique in a routine dose of 70-72 Gy to the primary tumor and metastatic lymph nodes. In case of residual primary lesion, a boost dose of 8-24 Gy was delivered by either 192Ir afterloading brachytherapy, fractionated stereotactic radiotherapy, conformal radiotherapy, or small external-beam fields. RESULTS: The 5-year and 10-year local-regional control, overall survival, and disease-free survival rates were 81.7% and 76.7%, 76.1% and 66.5%, 58.4% and 52.1%, respectively. In case of residual primary lesions after a dose of 70-72 Gy of conventional external-beam radiotherapy (EBRT), an additional boost was able to achieve a local control of 80.8%, similar to that obtained with primary lesions that completely disappeared at 70-72 Gy (82.6%, p = 0.892). CONCLUSIONS: The treatment results of radical EBRT followed by a boost dose to the residual primary tumor for nasopharyngeal carcinoma in our institution are promising. 相似文献

PURPOSE: To identify prognostic factors and treatment toxicity in a series of operable endometrial adenocarcinomas. PATIENTS AND METHODS: Between November 1971 and October 1992, 437 patients (pts) with endometrial carcinoma, staged according to the 1988 FIGO staging system, underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy without (n = 140) or with (n = 297) pelvic lymph node dissection. The chronology of RT was not randomized and depended on the usual practices of the surgical teams. Group I: 79 pts received preoperative uterovaginal brachytherapy (mean total dose [MD]: 57 Gy). Group II: 358 pts received postoperative RT (196 pts received vaginal brachytherapy alone [MD: 50 Gy], 158 pts had external beam pelvis RT [EPRT] [MD: 46 Gy over 5 weeks] followed by vaginal brachytherapy [MD: 17 Gy], and 4 pts had EPRT alone [MD: 46 Gy over 5 weeks]). The mean follow-up was 128 months. RESULTS: The 10-year disease-free survival rate was 86%. From 57 recurrences, 12 were isolated locoregionally. Multivariate analysis showed that independent factors decreasing the probability of disease-free survival were: histologic type (clear cell carcinoma, p = 0.038), largest histologic tumor diameter > 3 cm (p = 0.015), histologic grade (p = 0.008), myometrial invasion > 1/2 (p = 0.0055), and 1988 FIGO staging system (p = 9.10(-8)). In group II, the addition of EPRT did not seem to improve locoregional control. The postoperative complication rate was 7%. The independent factors increasing the risk of postoperative complications were FIGO stage (p = 0.02) and pelvic lymph node dissection (p = 0.011). The 10-year rate for grade 3 and 4 late radiation complications according to the LENT-SOMA scoring system was 3.1%. EPRT independently increased the 10-year rate for grade 3 and 4 late radiation complications (R.R.: 5.6, p = 0.0096). CONCLUSION: EPRT increases the risk of late radiation complications. After surgical and histopathologic staging with pelvic lymph node dissection, in a subgroup of intermediate risk patients (stage IA grade 3, IB-C and II), postoperative vaginal brachytherapy alone is probably sufficient to obtain a good therapeutic index. Results for patients with stage III tumor are not satisfactory. 相似文献

PURPOSE: To identify prognostic factors for local and distant relapse and perform risk stratification for patients with advanced cervical cancer treated with radiotherapy (RT) alone. METHODS AND MATERIALS: A total of 1031 patients with Stage IB-IVA squamous cell carcinoma of the cervix treated with full-course RT but without any chemotherapy were included for analysis. Of these, 311 patients with nonbulky Stage IB-IIA disease were designated the reference group and the other 720 patients were the study group. The associations of stage, squamous cell carcinoma antigen (SCC-ag) level, hemoglobin level, age, cell differentiation, and pelvic lymph node status with treatment failure were evaluated. The independent prognostic factors were identified by multivariate analysis. The study group was further stratified into subgroups using combinations of these risk factors. RESULTS: In the study group, independent risk factors for local relapse were advanced stage and age <45 years. The 5-year local relapse-free survival rate was 86% for patients > or =45 years with bulky Stage IB-IIA or IIB disease, and was even greater, up to 90% if the SCC-ag level was <2. In contrast, it was 65% for patients with Stage IIIB who were <45 years old. The independent risk factors for distant failure were advanced stage, SCC-ag level >2, and positive pelvic lymph nodes. The 5-year distant relapse-free survival rate was 83% for patients with bulky Stage IB-IIA and IIB disease, SCC-ag level <2, and negative lymph nodes and 43% for patients with Stage III, SCC-ag level >2, and positive lymph nodes. CONCLUSION: The risk of treatment failure in advanced-stage cervical cancer patients treated by RT alone can be more precisely predicted by risk stratification. A certain subgroup of patients had better control than the others. The benefit of treating these relatively low-risk patients with additional treatment such as concurrent chemotherapy should be further evaluated in prospective studies or meta-analyses. 相似文献
