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.

Abstract Objective: This study aimed to explore the clinical value of adjuvant chemotherapy (ACT) in locoregionally advanced nasopharyngeal carcinoma (LANC) following concurrent chemoradiotherapy (CCRT) and induction chemotherapy (ICT).Methods: We included 839 newly diagnosed LANC patients in the study. ICT plus CCRT (ICT+CCRT group) was administered to 443 patients and 396 patients who received ACT after receiving ICT plus CCRT (ICT+CCRT+ACT group). Univariate and multivariate Cox regression analyses were carried out in this study. Furthermore, to balance the study and control groups, propensity score matching (PSM) was applied.Results: 373 pairs of LANC patients were obtained after the PSM analysis. We found that ACT following ICT+CCRT had no significant effect on improving the survival of LANC patients. By further exploring the ICT+CCRT+ACT regimen, we excluded N0-1-positive patients and performed PSM in the ICT+CCRT and ICT+CCRT+ACT groups again. Each group consisted of 237 patients. Kaplan-Meier analysis revealed that there was a difference between the ICT+CCRT and ICT+CCRT+ACT groups in terms of the 5-year overall survival (OS) (78.9% vs. 85.0%, P = 0.034), disease-free survival (DFS) (73.4% vs. 81.7%, P = 0.029), and distant metastasis-free survival (DMFS) (84.9% vs. 76.0%, P = 0.019). In addition, the ICT+CCRT+ACT group had a higher incidence of grade 3-4 acute leukocytopenia/neutropenia.Conclusion: Compared with ICT+CCRT, ACT following ICT plus CCRT can reduce distant metastasis of N2-3-positive LANC and improve the OS and DFS of these patients, thus demonstrating higher clinical feasibility.

PURPOSE: Survival in advanced nasopharyngeal carcinoma (NPC) is compromised by distant metastasis. Because mitomycin is active against hypoxic and G0 cells, which may help to eradicate micrometastasis, we investigated the effect of mitomycin-containing cisplatin-based induction chemotherapy. PATIENTS AND METHODS: Recruited for this study were American Joint Committee on Cancer (AJCC) 1992 staging system stage IV NPC patients with the following adverse features: obvious intracranial invasion, supraclavicular or bilateral neck lymph node metastasis, large neck node (> 6 cm), or elevated serum lactate dehydrogenase (LDH) level. Patients were given three cycles of chemotherapy before radiotherapy. The chemotherapy comprised a 3-week cycle of mitomycin, epirubicin, and cisplatin on day 1 and fluorouracil and leucovorin on day 8 (MEPFL). RESULTS: From January 1994 to December 1997, 111 patients were recruited. The median follow-up period was 43 months. The actuarial 5-year overall survival rate was 70% (95% confidence interval [CI], 60% to 80%; n = 111). For patients having completed radiotherapy (n = 100), the 5-year locoregional control rate was 70% (95% CI, 55% to 84%) and the distant metastasis–free rate was 81% (95% CI, 73% to 89%). The 5-year distant metastasis–free rate of N3a and N3b disease of AJCC 1997 staging system were 79% (95% CI, 62% to 95%) and 74% (95% CI, 60% to 89%), respectively. By Cox multivariate analysis, high pretreatment serum LDH level (P = .04) and neck nodal enlargement before radiotherapy (P = .001) were adverse prognostic factors of survival. CONCLUSION: The good 5-year survival of N3 disease supports the effectiveness of induction MEPFL in the primary treatment of advanced NPC. Further investigation to incorporate concurrent chemoradiotherapy is warranted.

Nasopharyngeal carcinoma is a unique disease entity among head and neck cancers due to its epidemiology and clinical behavior. Non-keratinizing or undifferentiated carcinoma is the most common histological type in endemic areas. Radiotherapy is the treatment for early-stage disease. With the widespread use of IMRT, loco-regional control has improved significantly in locally advanced diseases. But distant metastasis continues to be the most common pattern of failure. To address this issue, chemotherapy has been incorporated into radiotherapy in various settings; as concurrent, induction, and adjuvant. The initial trials of concurrent chemotherapy incorporated adjuvant chemotherapy also and the magnitude of benefit contributed by each treatment was not clear. Later trials proved that adjuvant chemotherapy was not beneficial. Induction chemotherapy when added to concurrent chemoradiation resulted in improvement in Failure Free Survival, Overall Survival, and Distant Metastasis Free Survival. Thus, induction chemotherapy followed by concurrent chemoradiation became the standard of care for locally advanced disease (stage III and IVA). The role of chemotherapy in stage II disease is still evolving. Metastatic nasopharyngeal carcinoma is treated by platinum doublet chemotherapy, Cisplatin-gemcitabine is the standard regimen.
