PURPOSE: To assess the effect of adding neoadjuvant chemotherapy (NACT) to concurrent chemoradiotherapy (CCRT) in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) and undetectable pretreatment Epstein-Barr virus (pEBV) DNA. MATERIALS AND METHODS: We enrolled 639 NPC patients with stage II to IVB and undetectable pEBV DNA to receive CCRT with or without NACT. Radiotherapy was 2.0 to 2.27 Gy per fraction with five daily fractions per week for 6 to 7 weeks to the primary tumor and 62 to 70 Gy to the involved neck area. NACT was cisplatin (80-100 mg/m2 day 1) and 5-fluorouracil (800-1000 mg/m2, 120-hour continuous intravenous infusion) every 3 weeks for two or three cycles. CCRT was cisplatin (80-100 mg/m2 day 1) every 3 weeks for three cycles. RESULTS: For all patients, the 5-year overall survival (OS), locoregional relapse-free survival (LRFS), distant metastasis-free survival (DMFS), and progression-free survival (PFS) rates were 91.9%, 92.2%, 95.0%, and 86.4%, respectively. There was no significant difference in OS (5-year OS 90.8% [NACT + CCRT group] vs 92.7% [CCRT alone]; hazard ratio [HR] 1.24; P = .486), LRFS (HR 1.13, 95% confidence interval [CI] 0.59-2.14, P = .715), DMFS (HR 0.78, 95% CI 0.34-1.78, P = .554), or PFS (HR 1.21, 95% CI 0.75-1.95, P = .472). CONCLUSION: CCRT with or without NACT produced a good treatment outcome in patients with locoregionally advanced NPC and undetectable pEBV DNA, but NACT before CCRT did not significantly improve survival rates. 相似文献

Little is known about the value of adding concurrent chemotherapy (CC) to radiotherapy for stage II nasopharyngeal carcinoma (NPC) with undetectable (0 copies/mL) pretreatment Epstein-Barr Virus (EBV) DNA in the intensity-modulated radiotherapy (IMRT) era. To address this question, the present study retrospectively reviewed 514 patients with newly diagnosed stage II NPC and undetectable pretreatment EBV DNA from Sun Yat-sen University Cancer Center between March 2008 and October 2016. Clinical characteristics and survival outcomes between concurrent chemoradiotherapy (CCRT) and IMRT alone groups were compared. Propensity score matching analysis was conducted to control for confounding factors. Although CCRT group had significantly higher proportions of stage N1 disease than IMRT alone group before matching (85% vs. 61%, p < 0.001), no statistically significant differences were noted for OS (97.8% vs. 98.1%, p = 0.700), DFS (93.4% vs. 94.5%, p = 0.846), DMFS (96.0% vs. 96.9%, p = 0.762), and LRFS (97.3% vs. 98.1%, p = 0.701). After 1:1 propensity-score matching, 177 pairs were identified. Patients in each group were found to be well balanced in baseline characteristics and risk factors (all P > 0.05). The five-year OS (96.9% vs. 98.2%, p = 0.302), DFS (92.0% vs. 95.2%, p = 0.777), DMFS (95.2% vs. 97.6%, p = 0.896), and LRFS (97.3% vs. 97.6%, p = 0.328) rates remain comparable for both CCRT and RT alone groups. Additionally, subgroup analysis still failed to observe any significant survival benefit for the addition of CC to IMRT for N1 disease (P>0.05 for all). Our results indicated that IMRT alone appeared to achieve comparable survival to CCRT for stage II NPC with undetectable pretreatment EBV DNA.Keyword: Nasopharyngeal carcinoma, Epstein–Barr virus DNA, Survival, Intensity-modulated radiotherapy, Concurrent chemotherapy, Effect 相似文献

BACKGROUND: The effectiveness of induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) over CCRT alone in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) and chronic hepatitis B infection in the intensity-modulated radiotherapy (IMRT) era is unknown. PATIENTS AND METHODS: A total of 249 patients with stage T1-2 N2-3 or T3-4 N1-3 NPC and chronic hepatitis B infection treated with IMRT were retrospectively reviewed. Propensity score matching (PSM) was employed to balance covariates; 140 patients were propensity-matched (1:1 basis). Survival outcomes in the IC + CCRT and CCRT groups were compared using the Kaplan–Meier method, log-rank test and Cox proportional hazards model. RESULTS: No significant survival differences were observed between IC + CCRT and CCRT (5-year overall survival, 88.3% vs. 82.2%; P = .484; disease-free survival, 73.9% vs. 75.2%; P = .643; distant metastasis-free survival, 84.1% vs. 85.1%; P = .781; and locoregional failure-free survival, 87.9% vs. 85.1%; P = .834). After adjusting for known prognostic factors in multivariate analysis, IC was not an independent prognostic factor for any outcome (all P > .05); subgroup analysis based on T category (T1-2/T3-4), N category (N0-1/N2-3), and overall stage (III/IV) confirmed these results. The incidence of hepatic function damage in the IC + CCRT and CCRT groups was not significantly different. CONCLUSION: IC + CCRT leads to comparable survival outcomes and hepatic function damage compared to CCRT alone in patients with locoregionally advanced NPC with chronic hepatitis B infection in the IMRT era. Further investigations are warranted. 相似文献

Background
Guidelines from the U.S. National Comprehensive Cancer Network have recommended use of concurrent chemoradiotherapy (CCRT), followed by a 3-cycles combination of platinum and 5-fluorouracil chemotherapy as standard treatment for nasopharyngeal carcinoma (NPC). The benefits of CCRT for treatment of locally advanced NPC have been established. Whether platinum and 5-fluorouracil chemotherapy should be routinely added to locally advanced NPC after CCRT is still open to debate. Whether adjuvant chemotherapy provides an additional survival benefit for the subgroup of patients with residual nasopharyngeal carcinoma who have undergone CCRT is also unclear. This retrospective study was initiated to determine the survival benefit of adjuvant chemotherapy (AC) in residual NPC patients who have undergone concurrent chemoradiotherapy.Methods
The retrospective study included 155 nasopharyngeal carcinoma patients who had local residual lesions after the platinum-based CCRT without or with AC. Kaplan-Meier analysis and the log-rank test were used to estimate overall survival (OS), failure-free survival (FFS), local relapse-free survival (LRFS) and distant metastasis-free survival (DMFS).Results
Median follow-up was 47 months. Adjuvant cisplatin or nedaplatin plus 5-fluorouracil chemotherapy did not significantly improve 3-year OS, LRFS, FFS, and DMFS for patients with residual nasopharyngeal carcinoma after undergoing CCRT. The 3-year OS rates for the no-AC group and AC group were 71.6% and 73.7%, respectively (P= 0.44). The 3-year FFS rates for no-AC group and AC group were 57.5% and 66.9%, respectively ((P= 0.19). The 3-year LRFS rates for no-AC group and AC group were 84.7% and 87.9%, respectively ((P= 0.51). The 3-year DMFS rates for no-AC group and AC group were 71.4% and 77.4%, respectively ((P= 0.23).Conclusions
Since we did not find sufficient data to support significant survival in 3-year OS, LRFS, FFS, and DMFS, whether Adjuvant cisplatin or nedaplatin and 5-fluorouracil chemotherapy should be routinely added to residual nasopharyngeal carcinoma patients after undergoing CCRT remain uncertain. 相似文献5.

ObjectivesTo evaluate long-term outcomes of induction chemotherapy (IC) followed by intensity-modulated radiotherapy (IMRT) and adjuvant chemotherapy (AC) in nasopharyngeal carcinoma (NPC) patients with N3 disease.Materials and methodsFrom September 2005 to August 2016, 143 patients confirmed NPC with the 8th AJCC/UICC staging criteria N3 were reviewed. All patients received IC followed by IMRT and AC.ResultsAfter a median follow-up of 67 months, the 5-year and 10-year overall survival (OS), progression-free survival (PFS), distant metastasis free survival (DMFS), local progression-free survival (LPFS) and regional progression-free survival (RPFS) were 75.7% and 61.6%, 61.2% and 53.4%, 73.1% and 72.1%, 92.4% and 87%, 88.9% and 81.8%, respectively. Multivariate analyses indicated that T stage (P = 0.001) appeared to be prognostic factors for OS. T stage (P = 0.001 and P = 0.002) and neck lymph node necrosis (P = 0.015 and P = 0.045) were independent predictors of PFS and DMFS. The acute toxicities were mainly grade 1/2 hematologic toxicities in patients treated with IC+IMRT+AC, and severe toxicities were uncommon.ConclusionsIC followed by IMRT and AC achieved satisfactory long-term survival outcomes in NPC patients with N3 disease. Neck lymph node necrosis and late T stage served as predictors of poor prognosis for patients. 相似文献

Background
N-stage is related to distant metastasis in nasopharyngeal carcinoma (NPC) patients. The purpose of this study was to evaluate the efficacy and toxicity of different nedaplatin-based chemotherapy regimens in advanced N2-3 stage NPC patients treated with intensity modulated radiation therapy (IMRT).Patients and Methods
Between April 2005 and December 2009, a total of 128 patients with N2-3 advanced NPC were retrospectively analyzed. Patients were treated with IMRT concurrent with 2 cycles of chemotherapy consisting of either nedaplatin plus paclitaxel (NP group, n = 67) or nedaplatin plus fluorouracil and paclitaxel (NFP group, n = 61). Two to four cycles of adjuvant chemotherapy were then administered every 21 days following concurrent chemoradiotherapy.Results
With a median follow-up of 60 months, the 5-year overall survival (OS), progression-free survival (PFS), local-regional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) for all patients were 81.4%, 71.5%, 87.8% and 82.0%, respectively. No significant difference in PFS (66.6% vs. 76.7%, P = 0.212) and LRRFS rates (89.0% vs. 86.3%, P = 0.664) was observed between the NP and NFP groups. The 5-year OS (75.4% vs. 88.5%, P = 0.046) and DMFS (75.1% vs. 89.0%, P = 0.042) rate were superior in the NFP group compared with the NP group. The NFP group had a higher incidence of grade 3–4 acute toxicities including bone marrow suppression (leukopenia: χ2 = 3.935, P = 0.047; anemia: χ2 = 9.760, P = 0.002; thrombocytopenia: χ2 = 8.821, P = 0.003), and both liver and renal dysfunction (χ2 = 5.206, P = 0.023) compared with the NP group. Late toxicities were moderate and no difference was observed between the two groups.Conclusion
IMRT concurrent with nedaplatin-based chemotherapy is an advocated regimen for patients with advanced N2-3 stage NPC. Patients with advanced N2-3 stage may be better candidates for the NFP regimen although this regimen was associated with a high acute toxicity rate. 相似文献8.

Objective
To evaluate concurrent chemotherapy for T4 classification nasopharyngeal carcinoma (NPC) treated by intensity-modulated radiotherapy (IMRT).Methods
From July 2004 to June 2011, 180 non-metastatic T4 classification NPC patients were retrospectively analyzed. Of these patients, 117 patients were treated by concurrent chemoradiotherapy (CCRT) using IMRT and 63 cases were treated by IMRT alone.Results
The median follow-up time was 58.97 months (range, 2.79–114.92) months. For all the patients, the 1, 3 and 5-year local failure-free survival (LFFS) rates were 97.7%, 89.2% and 85.9%, regional failure free survival (RFFS) rates were 98.9%, 94.4% and 94.4%, distant failure-free survival (DFFS) rates were 89.7%, 79.9% and 76.2%, and overall survival (OS) rates were 92.7%, 78.9% and 65.3%, respectively. No statistically significant difference was observed in LFFS, RFFS, DFFS and OS between the CCRT group and the IMRT alone group. No statistically significant difference was observed in acute toxicity except leukopenia (p = 0.000) during IMRT between the CCRT group and the IMRT alone group.Conclusion
IMRT alone for T4 classification NPC achieved similar treatment outcomes in terms of disease local control and overall survival as compared to concurrent chemotherapy plus IMRT. However, this is a retrospective study with a limited number of patients, such results need further investigation in a prospective randomized clinical trial. 相似文献9.

OBJECTIVES: To report the long-term outcome and toxicity of locoregionally advanced nasopharyngeal carcinoma (LA NPC) treated with nimotuzumab (h-R3) plus intensity-modulated radiotherapy (IMRT) with or without chemotherapy. METHODS: From May 2008 to March 2014, 3022 newly histology-proven, nonmetastatic NPC patients were retrospectively reviewed; among them, 257 patients treated with h-R3 were enrolled in this study. The patients' age range was between 10 and 76 years. The distribution of patients by disease stage was 150 (58.4%) in stage III, 88 (34.2%) in stage IV A, and 19 (7.4%) in stage IV B. All the patients received the treatment of h-R3 plus IMRT, and from them, 239 cases were also treated with cisplatin-based chemotherapy. Acute and late radiation-related toxicities were graded according to the Acute and Late Radiation Morbidity Scoring Criteria of Radiation Therapy Oncology Group. The accumulated survival was calculated according to the Kaplan-Meier method. Log-rank test was used to compare the survival difference. Multivariate analysis was performed using Cox's proportional-hazard model. RESULTS: All 257 patients had completed combined treatment; 231 patients received h-R3 plus IMRT with induction chemotherapy (IC), while 26 patients received only h-R3 plus IMRT. With a median follow-up of 48 months (range, 13-75 months), the estimated 5-year local recurrence-free survival, regional recurrence-free survival, distant metastases-free survival, progression-free survival, and overall survival (OS) rates were 94.3%, 94.8%, 91.9%, 83.4%, and 86.2%, respectively. Univariate analysis showed that age, T stage, clinical stage, and IC were related with OS. Multivariate analysis indicated that T stage and IC were independent prognostic factors for OS. The incidence of grade 3 to 4 acute mucositis and leukocytopenia was 10.9% and 19.8%, respectively, with no cases of skin rash and infusion reaction. Xerostomia was the most common late complication, and the degree of dry mouth in most survivors was mild to moderate at the last follow-up time. CONCLUSION: h-R3 plus IMRT with or without chemotherapy showed promising outcomes in terms of locoregional control and survival without increasing the incidence of radiation-related toxicities for patients. 相似文献

OBJECTIVE: This study was conducted to assess the efficacy and safety of nimotuzumab combined with radiotherapy (RT) in elderly patients with nasopharyngeal carcinoma. MATERIALS AND METHODS: The clinical data of 75 nasopharyngeal carcinoma patients, who were initially treated with nimotuzumab combined with RT, were collected and retrospectively reviewed from December 2008 to April 2014. They were aged 60 to 81 years (median 64 years). The distribution of disease was stage II in 10 (13.3%), stage III in 33 (44.0%), and stage IV in 32 (42.7%). Among these patients, 59 cases received cisplatin-based chemotherapy. Survival outcomes and treatment toxicity were analyzed using IBM SPSS 19.0 software. RESULTS: With a median follow-up of 45 months (range, 13-78 months), the estimated 3-year local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), distant metastasis-free survival (DMFS), progression failure-free survival (PFS), and overall survival (OS) rates were 95.6%, 95.5%, 98.6%, 89.7%, and 89.2%, respectively. In the subgroup, 3-year OS rate in the patients with concurrent chemotherapy was 90.5% and 77.4% in patients without concurrent chemotherapy (Log-Rank = 1.795, P = .180). Univariate analysis showed that T stage and clinical stage were correlated with OS. Multivariate analysis indicated that age, T stage and tumor response at the end of treatment were independent prognosticators. Nine patients experienced grade 3 to 4 acute mucositis and 26 patients experienced grade 3-4 leukocytopenia, with no cases of skin rash and infusion reaction. Twelve patients developed mild liver function damage. No serious gastrointestinal or renal toxicities were observed. CONCLUSION: The efficacy of combined nimotuzumab with RT in elderly NPC patients was encouraging and the toxicities were accepted. In addition, nimotuzumab provides a better option for elderly patients who cannot be tolerate chemotherapy. 相似文献

PURPOSE: It deserves investigation whether induction chemotherapy (IC) followed by intensity-modulated radiotherapy (IMRT) is inferior to the current standard of IMRT plus concurrent chemotherapy (CC) in locoregionally advanced nasopharyngeal carcinoma. METHODS: Patients who received IC (94 patients) or CC (302 patients) plus IMRT at our center between March 2003 and November 2012 were retrospectively analyzed. Propensity-score matching method was used to match patients in both arms at equal ratio. Failure-free survival (FFS), overall survival (OS), distant metastasis–free survival (DMFS), and locoregional relapse–free survival (LRFS) were assessed with Kaplan-Meier method, log-rank test, and Cox regression. RESULTS: In the original cohort of 396 patients, IC plus IMRT resulted in similar FFS (P = .565), OS (P = .334), DMFS (P = .854), and LRFS (P = .999) to IMRT plus CC. In the propensity-matched cohort of 188 patients, no significant survival differences were observed between the two treatment approaches (3-year FFS 80.3% vs 81.0%, P = .590; OS 93.4% vs 92.1%, P = .808; DMFS 85.9% vs 87.7%, P = .275; and LRFS 93.1% vs 92.0%, P = .763). Adjusting for the known prognostic factors in multivariate analysis, IC plus IMRT did not cause higher risk of treatment failure, death, distant metastasis, or locoregional relapse. CONCLUSIONS: IC plus IMRT appeared to achieve comparable survival to IMRT plus CC in locoregionally advanced nasopharyngeal carcinoma. Further investigations were warranted. 相似文献

Objective: Clinical stage (cStage) in thyroid cancer determines extent of surgical therapy and completeness of resection. Pathologic stage (pStage) is an important determinant of outcome. The rate of discordance between clinical and pathologic stage in thyroid cancer is unknown.Methods: The National Cancer Data Base was queried to identify 27,473 patients ≥45 years old with cStage I through IV differentiated thyroid cancer undergoing surgery from 2008–2012.Results: There were 16,286 (59.3%) cStage I patients; 4,825 (17.6%) cStage II; 4,329 (15.8%) cStage III; and 2,013 (7.3%) cStage IV patients. The upstage rate was 15.1%, and the downstage rate was 4.6%. For cStage II, there was a 25.5% upstage rate. The change in cStage was a result of inaccurate T-category in 40.8%, N-category in 36.3%, and both in 22.9%. On multivariate analysis, the patients more likely to be upstaged had papillary histology, tumors 2.1 to 4 cm, total thyroidectomy, nodal surgery, positive margins, or multifocal disease. Upstaged patients received radioiodine more frequently (75.3% vs. 48.1%; P<.001).Conclusion: Approximately 20% of cStage is discordant to pStage. Certain populations are at risk for inaccurate staging, including cT2 and cN0 patients. Upstaged patients are more likely to receive radioactive iodine therapy.Abbreviations: CI = confidence interval; cStage = clinical stage; DTC = differentiated thyroid cancer; NCDB = National Cancer Data Base; OR = odds ratio; pStage = pathologic stage; RAI = radioactive iodine 相似文献

Background and purpose
The benefit of concurrent chemoradiotherapy (CCRT) in elderly patients with inoperable esophageal squamous cell carcinoma (SCC) is controversial. This study aimed to assess the efficiency and safety of CCRT in elderly thoracic esophageal cancer patients.Methods and materials
Between January 2002 and December 2011, 128 patients aged 65 years or older treated with CCRT or radiotherapy (RT) alone for inoperable thoracic esophageal SCC were analyzed retrospectively (RT alone, n = 55; CCRT, n = 73).Results
No treatment-related deaths occurred and no patients experienced any acute grade 4 non-hematologic toxicities. Patients treated with CCRT developed more severe acute toxicities than patients who received RT alone. The 3-year overall survival (OS) rate was 36.1% for CCRT compared with 28.5% following RT alone (p = 0.008). Multivariate analysis identified T stage and treatment modality as independent prognostic factors for survival. Further analysis revealed that survival was significantly better in the CCRT group than in the RT alone group for patients ≤ 72 years. Nevertheless, the CCRT group had a similar OS to the RT group for patients > 72 years.Conclusion
Our results suggest that elderly patients with inoperable thoracic esophageal SCC could benefit from CCRT, without major toxicities. However, for patients older than 72 years, CCRT is not superior to RT alone in terms of survival benefit. 相似文献14.

Background
The International Union Against Cancer/American Joint Committee on Cancer (UICC/AJCC) TNM staging system of nasopharyngeal carcinoma (NPC) is the most important system for survival prediction. The TNM 7th edition UICC/AJCC TNM staging system for NPC was adopted in January 2009, and is now internationally recommended. In comparison with the TNM 6th edition, there were several revisions in the new edition staging system. This study aims to evaluate the prognostic value of the TNM 7th edition for NPC patients in comparison with the TNM 6th edition.Method
Clinical data of 2,629 NPC patients from the Sun Yat-sen University Cancer Center between January 2006 and December 2010 were retrospectively collected and all the patients were restaged according to the criteria of the TNM 6th edition and TNM 7th edition UICC/AJCC staging manual. Univariate and multivariate COX proportional hazards analyses were applied to evaluate the prognostic values between adjacent stage categories of the TNM 6th edition and TNM 7th edition.Results
In comparison with the TNM 6th edition, a significant alteration of the distribution of N categories was observed when the TNM 7th edition was applied (χ2 = 20.589, P<0.001), with 119 (119/670, 17.8%) patients up-staging from N0 to N1. With regard to T and overall stage, 37 (37/561, 6.6%) patients were down-staged from T2a with the TNM 6th edition to T1 with the TNM 7th edition, and finally two patients were up-staged to overall stage II (2/118, 1.7%). Moreover, the survival curves were significantly segregated (P<0.05) between T1 and T2 as well as N1 and N2 with the TNM 7th edition.Conclusions
The TNM 7th edition led to a significant alteration in the distribution of N categories and it is superior to the TNM 6th edition in predicting the frequency of overall survival and distant metastasis-free survival. 相似文献15.

This study aimed to investigate the expression pattern and prognostic value of friend leukemia virus integration 1 (FLI-1) in nasopharyngeal carcinoma (NPC). Immunohistochemistry (IHC) staining of FLI-1 was performed in specimens from 198 untreated NPC patients. Ninety-nine patients were randomly assigned to the training set to analyze the prognostic value of FLI-1 and other clinicopathological characteristics, while the others were assigned to the testing set for validation. Clinicopathological data were compared using the Pearson chi-square test. Univariate and multivariate analyses were performed using the Cox proportional hazards model to test independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI). Cytoplasmic FLI-1 expression positively correlated with N stage, distant metastasis and death (P< 0.05) and also predicted poorer overall survival (OS) (P= 0.014), distant metastasis-free survival (DMFS) (P= 0.010), progression-free survival (PFS) (P= 0.031). In multivariate analysis, FLI-1 expression and clinical stage were both independent prognostic factors of poor OS and DMFS. Prognoses of patients in the training set, the testing set, and the entire set were clearly divided into four risk subgroups by supplementing FLI-1 with clinical stage. These results indicate that FLI-1 expression is an independent prognostic factor for NPC patients and suggest that supplementing FLI-1 with clinical stage could be helpful for more accurate risk definition. 相似文献

The prognostic value of Ki-67 in nasopharyngeal carcinoma (NPC) was controversial according to previous studies. We aimed to clarify the association between K-67 expression and survival in NPC through meta-analysis. We conducted a meta-analysis to explore the potential prognostic effect of Ki-67 on overall survival (OS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and local recurrence-free survival (LRFS) in NPC. A total of 13 studies comprising 1314 NPC patients were included. High Ki-67 expression was associated with poor OS (hazard ratio [HR]= 2.70, 95% confidence interval [CI]= 1.97–3.71, P<0.001), DFS (HR = 1.93, 95% CI = 1.49–2.50, P<0.001), and LRFS (HR = 1.86, 95% CI = 1.11–3.12, P=0.019). However, there was no significant association between Ki-67 and DMFS (HR = 1.37, 95% CI = 0.78–2.38, P=0.270). Furthermore, the prognostic role of Ki-67 was maintained throughout different sample sizes, analyses of HR, and study designs for OS and DFS in various subgroups.

Elderly patients with esophageal carcinoma may benefit from concurrent chemoradiotherapy (CCRT). However, the optimal concurrent chemotherapy regimen has not been determined. The aim of our study was to assess the efficiency and tolerance of treatment with a concurrent 5-fluorouracil (5-Fu)–based regimen and a taxane-based regimen combined with radiotherapy in elderly patients with esophageal squamous cell carcinoma (ESCC). A total of 46 patients with ESCC aged older than 65 years were included in this study. The patient population was divided into two treatment groups: 24 patients who received CCRT with a 5-Fu–based regimen were allocated to the PF group, and 22 patients who received CCRT with a taxane-based regimen were allocated to the DP group. The median overall survival (OS), median progression-free survival (PFS), overall response rate, and treatment-related toxicity were assessed. For patients in the PF group, the median OS time was 27.8 ± 9.1 months, and the median PFS time was 12.5 ± 2.7 months. Patients in the DP group had comparable survival outcomes, with a median OS time of 34.4 ± 6.4 months and a median PFS time of 21.1 ± 6.4 months (P = .296 and P = .115, respectively). Grade ≥3 leukocytopenia and grade ≥2 anemia occurred in 63.6% and 59.1% of patients in the DP group, respectively, and in 25.0% and 16.7% of patients in the PF group, respectively. Our results suggest that CCRT with a taxane-based regimen results in a higher incidence of treatment-related toxicity than CCRT with a 5-Fu–based regimen but comparable survival outcomes. 相似文献

Background
The development of intensity-modulated radiotherapy (IMRT) has revolutionized the management of nasopharyngeal carcinoma (NPC). The purpose of this study was to evaluate the prognostic value and classification of TNM stage system for retropharyngeal lymph node (RLN) metastasis in NPC in the IMRT era.Material and Methods
We retrospectively reviewed data from 749 patients with biopsy-proven, non-metastatic NPC. All patients received IMRT as the primary treatment. Chemotherapy was administered to 86.2% (424/492) of the patients with stage III or IV disease.Results
The incidence of RLN metastasis was 64.2% (481/749). Significant differences were observed in the 5-year disease-free survival (DFS; 70.6% vs. 85.4%, P<0.001) and distant metastasis-free survival (DMFS; 79.2% vs. 90.1%, P<0.001) rates of patients with and without RLN metastasis. In multivariate analysis, RLN metastasis was an independent prognostic factor for disease failure and distant failure (P = 0.005 and P = 0.026, respectively), but not for locoregional recurrence. Necrotic RLN metastases have a negative effect on disease failure, distant failure and locoregional recurrence in NPC with RLN metastasis (P = 0.003, P = 0.018 and P = 0.005, respectively). Survival curves demonstrated a significant difference in DFS between patients with N0 disease and N1 disease with only RLN metastasis (P = 0.020), and marginally statistically significant differences in DMFS and DFS between N1 disease with only RLN metastasis and other N1 disease (P = 0.058 and P = 0.091, respectively). In N1 disease, no significant differences in DFS were observed between unilateral and bilateral RLN metastasis (P = 0.994).Conclusions
In the IMRT era, RLN metastasis remains an independent prognostic factor for DFS and DMFS in NPC. It is still reasonable for RLN metastasis to be classified in the N1 disease, regardless of laterality. However, there is a need to investigate the feasibility of classifying RLN metastasis as N1a disease in future by a larger cohort study. 相似文献20.

PurposeTo evaluate the predictive and prognostic value of pretreatment metabolic tumor volume (MTV) in patients with treated by radiotherapy (RT) or concurrent chemoradiotherapy (CCRT).MethodsWe reviewed the records of 118 patients with newly diagnosed laryngeal carcinoma, who had been treated by RT or CCRT. Pretreatment positron emission tomography (PET) was performed, and MTV values were obtained by contouring margins of standardized uptake value. Clinical factors and MTV were analyzed for their association with survival.ResultsPatients with residual disease showed a significantly higher MTV than those with a complete response (CR) after primary treatment. Univariate analysis showed that the patients with a high MTV had a significantly lower disease-free survival (DFS) (p < 0.001). Subsite (p = 0.010), T-stage (p < 0.001), nodal metastasis (p < 0.001) and clinical stage (p < 0.001) also correlated significantly with DFS. In the multivariate analysis, MTV and clinical stage were both found to be independent prognostic factors for DFS (p = 0.001, p = 0.034, respectively). The 3-year DFS for patients with a high MTV were significantly poorer than those with a low MTV (p < 0.001).ConclusionsMTV of the primary tumor is a significant prognostic factor for DFS in patients with laryngeal carcinoma treated by RT or CCRT. The results imply that MTV could be an important factor when planning treatment and follow-up for patients with laryngeal carcinoma. 相似文献
