Background: This study aimed to investigate the efficiency and toxicities of concurrent chemoradiotherapy (CCRT) and induction chemotherapy (IC) followed by radiotherapy (RT) in different risk locoregionally advanced nasopharyngeal carcinoma (NPC). Methods: A total of 1814 eligible patients with stage II–IVB disease treated with CCRT or IC plus RT were included. The overall survival (OS), progression-free survival (PFS) and distant metastasis-free survival (DMFS) were calculated using the Kaplan–Meier method, and the differences were compared using the log-rank test. Results: Nomograms were developed to predict OS, PFS and DMFS (C-index: 0.71, 0.70 and 0.71, respectively). Patients were then divided into three different risk groups based on the scores calculated by the nomogram for OS. In the low and intermediate-risk group, no significant survival differences were observed between patients treated with IC plus RT alone and CCRT (5-year OS, 97.3% versus 95.6%, p = 0.642 and 87.6% versus 89.7%, p = 0.381, respectively; PFS, 95.9% versus 95.6%, p = 0.325 and 87.6% versus 89.0%, p = 0.160, respectively; DMFS, 97.2% versus 94.8%, p = 0.339 and 87.2% versus 89.3%, p = 0.628, respectively). However, in the high-risk group, IC plus RT displayed an unfavorable 5-year OS (71.0% versus 77.2%, p = 0.022) and PFS (69.4.0% versus 75.4%, p = 0.019) compared with CCRT. A significantly higher incidence of grade 3 and 4 adverse events was documented in patients treated with CCRT than in those treated with IC plus RT in all risk groups ( p = 0.040). Conclusion: IC followed by RT represents an alternative treatment strategy to CCRT for patients with low and intermediate-risk NPC, but it is not recommended for patients with high-risk NPC.

PURPOSE The treatment of childhood nasopharyngeal carcinoma has been adapted from adult regimens; pediatric-specific studies are limited. The ARAR0331 study sought to evaluate the impact of induction chemotherapy (IC) and concurrent chemoradiotherapy (CCR). PATIENTS AND METHODS Patients with American Joint Committee on Cancer stages IIb to IV were scheduled to receive three cycles of IC with cisplatin and fluorouracil, followed by CCR with three cycles of cisplatin. Patients with complete or partial response to IC received 61.2 Gy to the nasopharynx and neck, and patients with stable disease received 71.2 Gy. RESULTS Between February 2006 and January 2012, 111 patients (75 male) were enrolled. Median age was 15 years, and 46.8% of the patients were African American. After a feasibility analysis, the study was amended to reduce cisplatin to two cycles during CCR. The 5-year event-free survival (EFS) and overall survival estimates were 84.3% and 89.2%, respectively. The 5-year EFS for stages IIb, III, and IV were 100%, 82.8%, and 82.7%, respectively. The 5-year cumulative incidence estimates of local, distant, and combined relapse were 3.7%, 8.7%, and 1.8%, respectively. Patients treated with three versus two CCR cycles of cisplatin had improved 5-year postinduction EFS (90.7% v 81.2%, P = .14). CONCLUSION Patients in ARAR0331 were characterized by advanced disease and by a high proportion of black children and adolescents. Treatment with IC and CRT resulted in excellent outcomes. A radiation dose reduction is possible for patients responding to IC. Although the outcomes are comparable, we observed a trend toward decreased EFS for patients assigned to receive fewer doses of cisplatin during CCR.

Background: The treatment effects of cumulative cisplatin dose (CCD) during radiotherapy (RT) following induction chemotherapy (IC) have not been determined for patients with locoregionally advanced nasopharyngeal carcinoma (NPC). Methods: A total of 3460 patients with locoregionally advanced NPC who were treated with IC plus cisplatin-based concurrent chemoradiotherapy or RT alone were included in this retrospective study. Three CCD groups (0 mg/m2 ⩽ CCD <100 mg/m2, 100 mg/m2 ⩽ CCD <200 mg/m2, CCD ⩾200 mg/m2) were balanced through the inverse probability of treatment weighting based on propensity scores estimated by a general boosted model. The primary endpoint was overall survival (OS); the secondary endpoints were distant metastasis-free survival (DMFS) and locoregional recurrence-free survival (LRFS). Results: CCD ⩾200 mg/m2 and <200 mg/m2 exhibited similar treatment effects for OS and DMFS, and were both superior to CCD <100 mg/m2 for OS and DMFS in patients with stage IVa NPC. The three CCD groups achieved similar treatment effects for patients with stage II–III NPC. After IC, CCD during RT appeared to exert little treatment effect on LRFS. Conclusion: The CCD during RT exerts treatment effects and improves OS by reducing the risk of distant metastasis for patients with stage IVa NPC following IC, and CCD <200 mg/m2 (mainly 160 mg/m2 in this group) is recommended. However, RT alone may be sufficient after IC in patients with stage II–III NPC.
