CONCLUSION

Overall, our current study showed the indirect results of comparing CRT + adjuvant with induction + CRT in locoregionally advanced NPC and found that they were equally effective but both better than CRT alone. Future head-to-head clinical trials were needed to provide more conclusive evidence for optimal treatment strategy in advanced NPC.
