Induction gemcitabine and cisplatin in locoregionally advanced nasopharyngeal carcinoma.

ABSTRACT: The standard of care for patients with locoregionally advanced nasopharyngeal carcinoma is concurrent platinum-based chemoradiotherapy. Existing literature have demonstrated that the addition of gemcitabine and cisplatin as induction chemotherapy in locoregionally advanced nasopharyngeal carcinoma may have promising efficacy but were from phase 2 clinical trials. Stronger evidence-based data in forms of phase 3 clinical trial investigating the survival benefits of adding gemcitabine and cisplatin induction chemotherapy for such patients have been urgently warranted. In one of our recent studies published in the New England Journal of Medicine, "Gemcitabine and cisplatin induction chemotherapy in nasopharyngeal carcinoma", 480 locoregionally advanced nasopharyngeal carcinoma patients from 12 hospitals across China were randomly assigned in a 1:1 ratio to receive either chemoradiotherapy alone or gemcitabine plus cisplatin and chemoradiotherapy. Our findings evinced that, as compared to chemoradiotherapy alone, the addition of induction chemotherapy comprising of gemcitabine plus cisplatin to concurrent cisplatin-radiotherapy to patients with locoregionally advanced nasopharyngeal carcinoma was safe, demonstrated improved recurrence-free survival, overall survival, and distant recurrence-free survival, and marginally superior locoregional recurrence-free survival.

Project description:BackgroundInduction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) for non-metastatic locoregionally advanced nasopharyngeal carcinoma (NPC) has gained considerable attention. However, the most efficacious IC regimens remain investigational. We aimed to compare the survival benefits of all available IC regimens followed by CCRT in this network meta-analysis.MethodsAll randomized-controlled trials of CCRT with or without IC in non-metastatic locoregionally advanced NPC were included, with an overall nine trials of 2,705 patients counted in the analysis. CCRT alone was the reference category. Eight IC regimens followed by CCRT were analyzed: docetaxel + cisplatin (DC), gemcitabine + carboplatin + paclitaxel (GCP), gemcitabine + cisplatin (GP), mitomycin + epirubicin + cisplatin + fluorouracil + leucovorin (MEPFL), cisplatin + epirubicin + paclitaxel (PET), cisplatin + fluorouracil (PF), cisplatin + capecitabine (PX) and cisplatin + fluorouracil (PF), cisplatin + capecitabine (PX). Fixed-effects frequentist network meta-analysis models was applied and P-score was used to rank the treatments.ResultsDC, GP, and PX were the top three IC regimens with the highest probability of benefit on overall survival (OS). Their corresponding hazard ratios (HRs) (95% CIs) compared with CCRT alone were of 0.24 (0.08-0.73), 0.43 (0.24-0.77), and 0.54 (0.27-1.09) and the respective P-scores were 94%, 82%, and 68%. The first three IC regimens showing significantly improved progression-free survival (PFS) were PX, followed by GP and DC with respective HRs of 0.46 (0.24-0.88), 0.51 (0.34-0.77), and 0.49 (0.20-1.20), and P-scores of 82%, 78%, and 74%. Among the studies in the intensity-modulated radiation therapy (IMRT) era, GP and PX were the best performed IC regimens, whilst DC performed the best among non-IMRT studies. Doublet and gemcitabine-based IC regimens had better survival benefits compared to triplet and taxane-based IC regimens, respectively.ConclusionsGiven its consistent superiority in both OS and PFS, DC, GP, and PX ranked among the three most efficacious IC regimens in both the overall and subgroup analysis of IMRT or non-IMRT studies. Exploratory analyses suggested that doublet and gemcitabine-based IC regimens showed better survival performance.
