ABSTRACT
BACKGROUND:
Locoregionally advanced nasopharyngeal carcinoma has high risk of distant metastasis and mortality. Induction chemotherapy is commonly administrated in clinical practice, but the efficacy was quite controversial in and out of randomized controlled trials. We thus conducted this pairwise meta-analysis. MATERIALS ANDMETHODS:
Trials that randomized patients to receive radiotherapy or concurrent chemoradiotherapy with or without induction chemotherapy were identified via searches of PubMed, MEDLINE, and ClinicalTrials.gov.RESULTS:
A total of ten trials (2,627 patients) were included. The pooled hazard ratios (HRs) based on fixed effect model were 0.68 (95% confidence interval [CI] 0.56-0.80, p < .001) for overall survival (OS) and 0.70 (95% CI 0.61-0.79, p < .001) for progression-free survival (PFS), which strongly favored the addition of induction chemotherapy. The absolute 5-year survival benefits were 8.47% in OS and 10.27% in PFS, respectively. In addition, based on the available data of eight trials, induction chemotherapy showed significant efficacy in reducing locoregional failure rate (risk ratio [RR] = 0.81, 95% CI 0.68-0.96, p = .017) and distant metastasis rate (RR = 0.69, 95% CI 0.58-0.82, p < .001).CONCLUSION:
This pairwise meta-analysis confirms the benefit in OS, PFS, and locoregional and distant controls associated with the addition of induction chemotherapy in nasopharyngeal carcinoma. IMPLICATIONS FOR PRACTICE According to the results of this meta-analysis of ten trials, induction chemotherapy can prolong overall survival and progression-free survival and improve locoregional and distant controls for nasopharyngeal carcinoma.Palavras-chave
