There are still many unresolved questions in the management of locally advanced Head and Neck Cancer (HNC). Many chemotherapeutic drugs and radiotherapy fractionation schemes are available and not all have been evaluated in head-to-head clinical trials. This systematic review and Bayesian network meta-analysis aims to compare the available treatment strategies and chemotherapeutic options for locally advanced HNC. ⋯ From the 57 included trials, including 15,723 patients, was possible to conduct analysis on 26 treatments for OS, 22 treatments for PFS and 10 treatments for toxicity. In terms of OS Concurrent chemoradiotherapy (CCRT) with cisplatin (HR 0.70, 95% CrI [credible interval] 0.62-0.78) and cetuximab on top of CCRT (HR 0.7, 95% CrI 0.5-0.97) are clearly superior to conventional RT alone. Induction chemotherapy (IC) with cisplatin and fluorouracil (HR 0.74, 95% CrI 0.52-0.95), IC with docetaxel, cisplatin, fluorouracil (HR 0.55, 95% CrI 0.54-0.89) and IC with paclitaxel, cisplatin, fluorouracil (HR 0.55, 95% CrI 0.34-0.89) before CCRT are all superior to conventional RT. CCRT with cisplatin is also superior to altered fractionation RT (HR 0.74, 95% CrI 0.64-0.84). Altered fractionation RT is not superior to conventional RT (HR 0.95, 95% CrI 0.85-1.06). Regarding PFS, CCRT with cisplatin (HR 0.72, 95% CrI 0.63-0.83), cisplatin and fluorouracil (HR 0.67, 95% CrI 0.5-0.88), carboplatin (HR 0.63, 95% CrI 0.46-0.87), carboplatin and fluorouracil (HR 0.75, 95% CrI 0.56-1), IC with cisplatin and fluorouracil (HR 0.59, 95% CrI 0.45-0.78), IC with docetaxel, cisplatin and fluorouracil (HR 0.53, 95% CrI 0.41-0.68) and IC with paclitaxel, cisplatin and fluorouracil (HR 0.59, 95% CrI 0.35-0.99) are superior to conventional RT and altered fractionation RT. IC with docetaxel, cisplatin and fluorouracil shows a significant superiority against CCRT with cisplatin (HR 0.73 95% CrI 0.58-0.92). Altered fractionation RT is not superior to conventional RT (HR 0.91, 95% CrI 0.81-1.02). Altered fractionation increases the risk of developing grade 3-4 mucositis compared to conventional RT (OR 3.74 95% 1.64-8.67) INTERPRETATION: CCRT with cisplatin remains the gold standard of treatment. Taxane based IC regimens may have a impact on locally advanced disease. Altered fractionation RT is inferior to CCRT and also does not seem to be meaningfully better than conventionally fractionated RT alone. Its role in locally advanced disease should be reevaluated.

This study aimed to evaluate the efficacy and safety in locoregionally advanced nasopharyngeal carcinoma (NPC) patients receiving concurrent chemoradiotherapy (CCRT) plus Cetuximab (CTX) or Nimotuzumab (NTZ) compared to those receiving induction chemotherapy (IC) plus CCRT. ⋯ The median follow-up was 57.0 months and 55.0 months for the CTX/NTZ plus CCRT group and IC plus CCRT group, respectively. No significant differences were found between the CTX/NTZ plus CCRT group and the IC plus CCRT group in 3-year OS (95.5% vs. 94.7%, P = 0.083), 3-year DFS (93.3% vs. 86.1%, P = 0.104), 3-year DMFS (96.2% vs. 92.5%, P = 0.243) and 3-year LRRFS (97.0% vs. 95.1%, P = 0.297). Patients undergoing IC plus CCRT suffered from severe hematologic toxicity and diarrhea compared with those treated with CTX/NTZ plus CCRT. The combination of CTX/NTZ with CCRT is comparable to IC plus CCRT treatment in survival outcomes for locoregionally advanced NPC patients but has a better safety profile than IC plus CCRT treatment.
