Effect of Induction Chemotherapy With Paclitaxel, Cisplatin, and Capecitabine vs Cisplatin and Fluorouracil on Failure-Free Survival for Patients With Stage IVA to IVB Nasopharyngeal Carcinoma: A Multicenter Phase 3 Randomized Clinical Trial.

ABSTRACT:

Importance

Induction chemotherapy added to concurrent chemoradiotherapy significantly improves survival for patients with locoregionally advanced nasopharyngeal carcinoma, but the optimal induction regimen remains unclear.

Objective

To determine whether induction chemotherapy with paclitaxel, cisplatin, and capecitabine (TPC) improves survival vs cisplatin and fluorouracil (PF) prior to chemoradiotherapy for patients with stage IVA to IVB nasopharyngeal carcinoma.

Design, setting, and participants

This randomized, open-label, phase 3 clinical trial recruited 238 patients at 4 hospitals in China from October 20, 2016, to August 29, 2019. Patients were 18 to 65 years of age with treatment-naive, nonkeratinizing stage IVA to IVB nasopharyngeal carcinoma and an Eastern Cooperative Oncology Group performance status of 0 to 1.

Interventions

Patients were randomly assigned (1:1) to receive induction chemotherapy with two 21-day cycles of TPC (intravenous paclitaxel [150 mg/m2, day 1], intravenous cisplatin [60 mg/m2, day 1], and oral capecitabine [1000 mg/m2 orally twice daily, days 1-14]) or PF (intravenous cisplatin [100 mg/m2, day 1] and fluorouracil [800 mg/m2 daily, days 1-5]), followed by chemoradiotherapy.

Main outcomes and measures

The primary end point was failure-free survival in the intention-to-treat population. Secondary end points included distant metastasis-free survival, locoregional relapse-free survival, overall survival, tumor response, and safety.

Results

Overall, 238 eligible patients (187 men [78.6%]; median age, 45 years [range, 18-65 years]) were randomly assigned to receive TPC (n = 118) or PF (n = 120). The median follow-up duration was 48.4 months (IQR, 39.6-53.3 months). Failure-free survival at 3 years was 83.5% (95% CI, 77.0%-90.6%) in the TPC group and 68.9% (95% CI, 61.1%-77.8%) in the PF group (stratified hazard ratio [HR] for recurrence or death, 0.47; 95% CI, 0.28-0.79; P = .004). Induction with the TPC regimen resulted in a significant reduction in the risk of distant metastases (stratified HR, 0.49 [95% CI, 0.24-0.98]; P = .04) and locoregional recurrence (stratified HR, 0.40 [95% CI, 0.18-0.93]; P = .03) compared with the PF regimen. However, there was no effect on early overall survival (stratified HR, 0.45 [95% CI, 0.17-1.18]; P = .10). The incidences of grade 3 to 4 acute adverse events and late-onset toxicities were 57.6% (n = 68) and 13.6% (16 of 118), respectively, in the TPC group and 65.8% (n = 79) and 17.9% (21 of 117), respectively, in the PF group. One treatment-related death occurred in the PF group.

Conclusions and relevance

This randomized clinical trial found that induction chemotherapy with 2 cycles of TPC for patients with stage IVA to IVB nasopharyngeal carcinoma improved failure-free survival compared with 2 cycles of PF, with no increase in the toxicity profile.

Project description:ObjectiveTo compare the effectiveness and safety of nab-paclitaxel, cisplatin, and capecitabine (nab-TPC) with gemcitabine and cisplatin as an alternative first line treatment option for recurrent or metastatic nasopharyngeal carcinoma.DesignPhase 3, open label, multicentre, randomised trial.SettingFour hospitals located in China between September 2019 and August 2022.ParticipantsAdults (≥18 years) with recurrent or metastatic nasopharyngeal carcinoma.InterventionsPatients were randomised in a 1:1 ratio to treatment with either nab-paclitaxel (200 g/m2 on day 1), cisplatin (60 mg/m2 on day 1), and capecitabine (1000 mg/m2 twice on days 1-14) or gemcitabine (1 g/m2 on days 1 and 8) and cisplatin (80 mg/m2 on day 1).Main outcome measuresProgression-free survival was evaluated by the independent review committee as the primary endpoint in the intention-to-treat population.ResultsThe median follow-up was 15.8 months in the prespecified interim analysis (31 October 2022). As assessed by the independent review committee, the median progression-free survival was 11.3 (95% confidence interval 9.7 to 12.9) months in the nab-TPC cohort compared with 7.7 (6.5 to 9.0) months in the gemcitabine and cisplatin cohort. The hazard ratio was 0.43 (95% confidence interval 0.25 to 0.73; P=0.002). The objective response rate in the nab-TPC cohort was 83% (34/41) versus 63% (25/40) in the gemcitabine and cisplatin cohort (P=0.05), and the duration of response was 10.8 months in the nab-TPC cohort compared with 6.9 months in the gemcitabine and cisplatin cohort (P=0.009). Treatment related grade 3 or 4 adverse events, including leukopenia (4/41 (10%) v 13/40 (33%); P=0.02), neutropenia (6/41 (15%) v 16/40 (40%); P=0.01), and anaemia (1/41 (2%) v 8/40 (20%); P=0.01), were higher in the gemcitabine and cisplatin cohort than in the nab-TPC cohort. No deaths related to treatment occurred in either treatment group. Survival and long term toxicity are still being evaluated with longer follow-up.ConclusionThe nab-TPC regimen showed a superior antitumoural efficacy and favourable safety profile compared with gemcitabine and cisplatin for recurrent or metastatic nasopharyngeal carcinoma. Nab-TPC should be considered the standard first line treatment for recurrent or metastatic nasopharyngeal carcinoma. Longer follow-up is needed to confirm the benefits for overall survival.Trial registrationChinese Clinical Trial Registry ChiCTR1900027112.

Project description:PURPOSE:This trial aimed to assess the efficacy and safety of the paclitaxel plus fluorouracil regimen versus the cisplatin plus fluorouracil regimen in definitive concurrent chemoradiotherapy (dCRT) in patients with locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS:Patients with locally advanced ESCC were enrolled and randomly assigned to either the paclitaxel plus fluorouracil group or the cisplatin plus fluorouracil group. The patients in the paclitaxel plus fluorouracil group were treated with paclitaxel and fluorouracil one cycle per week in dCRT for five cycles followed by paclitaxel and fluorouracil one cycle per month in consolidation chemotherapy for two cycles. The patients in the cisplatin/5-fluorouracil group were treated with cisplatin and fluorouracil one cycle per month in dCRT for two cycles followed by two cycles in consolidation chemotherapy. The radiotherapy dose was 61.2 Gy delivered in 34 fractions. The primary end point was 3-year overall survival (OS). RESULTS:Four hundred thirty-six patients with ESCC in six centers were recruited at a 1:1 ratio between April 2012 and July 2015. The median follow-up of the surviving patients was 48.7 months (interquartile range, 42.6-60.9). The 3-year OS was 55.4% in the paclitaxel plus fluorouracil group and 51.8% in the cisplatin plus fluorouracil group (hazard ratio, 0.905 [95% CI, 0.698 to 1.172]; P = .448). The 3-year progression-free survival was also not significantly different between the paclitaxel plus fluorouracil group and the cisplatin plus fluorouracil group (43.7% v 45.5%, respectively; hazard ratio, 0.973 [95% CI, 0.762 to 1.243]; P = .828). Compared with the cisplatin plus fluorouracil group, the paclitaxel plus fluorouracil group had significantly lower incidences of acute grade 3 or higher anemia, thrombocytopenia, anorexia, nausea, vomiting, and fatigue (P < .05), but higher incidences of acute grade 3 or higher leukopenia, radiation dermatitis, and radiation pneumonitis (P < .05). CONCLUSION:The paclitaxel plus fluorouracil regimen did not significantly prolong the OS compared with the standard cisplatin plus fluorouracil regimen in dCRT in patients with locally advanced ESCC.
