Camrelizumab and apatinib plus induction chemotherapy and concurrent chemoradiotherapy in stage N3 nasopharyngeal carcinoma: a phase 2 clinical trial.

ABSTRACT: The antiangiogenic agent apatinib has been shown to clinically improve responses to immune checkpoint inhibitors in several cancer types. Patients with N3 nasopharyngeal carcinoma have a high risk of distant metastasis, however, if the addition of immunotherapy to standard treatment could improve efficacy is unclear. In this phase II clinical trial (ChiCTR2000032317), 49 patients with stage T_anyN3M0 nasopharyngeal carcinoma were enrolled and received the combination of three cycles of induction chemotherapy, camrelizumab and apatinib followed by chemoradiotherapy. Here we report on the primary outcome of distant metastasis-free survival and secondary end points of objective response rate, failure-free survival, locoregional recurrence-free survival, overall survival and toxicity profile. After induction therapy, all patients had objective response, including 13 patients (26.5%) with complete response. After a median follow-up of 28.7 months, the primary endpoint of 1-year distant metastasis-free survival was met for the cohort (1-year DMFS rate: 98%). Grade≥3 toxicity appeared in 32 (65.3%) patients, with the most common being mucositis (14[28.6%]) and nausea/vomiting (9[18.4%]). In this work, camrelizumab and apatinib in combination with induction chemotherapy show promising distant metastasis control with acceptable safety profile in patients with stage T_anyN3M0 nasopharyngeal carcinoma.

Project description:PurposeInduction chemotherapy plus concurrent chemoradiotherapy and concurrent chemoradiotherapy alone are both standard treatment regimens for managing locally advanced nasopharyngeal carcinoma. However, the results of comparisons between them in clinical trials vary. Therefore, we designed this meta-analysis to illustrate their advantages and disadvantages in patients with locally advanced nasopharyngeal carcinoma.MethodsWe thoroughly searched the PubMed, EMBASE, and Cochrane Library databases and then merged the effect indicators of hazard ratios and risk ratios using RevMan 5.1.ResultsSeven randomized controlled trials totaling 2,319 patients were included in our research. The synthesized results showed that induction chemotherapy plus concurrent chemoradiotherapy improved overall survival (HR = 0.75, 95% CI: 0.63-0.89, P = 0.001), progression-free survival (HR = 0.69, 95% CI: 0.60-0.80, P < 0.001), distant metastasis-free survival (HR = 0.65, 95% CI: 0.53-0.80, P < 0.001) and locoregional recurrence-free survival (HR = 0.68 95%, CI: 0.54-0.86, P = 0.001) versus concurrent chemoradiotherapy alone. It also increased the risk of anemia, thrombocytopenia, and neutropenia during concurrent chemoradiotherapy. However, the incidence of leukopenia and mucositis was similar in induction chemotherapy and induction chemotherapy plus concurrent chemoradiotherapy. Furthermore, the subgroup analysis showed better survival outcomes with induction chemotherapy plus concurrent chemoradiotherapy than with concurrent chemoradiotherapy alone in the triweekly cisplatin subgroup (all P < 0.01), whereas induction chemotherapy plus concurrent chemoradiotherapy could only improve progression-free survival and locoregional recurrence-free survival in the weekly cisplatin subgroup (HR = 0.78, P = 0.02; and HR = 0.66, P = 0.03, respectively).ConclusionsInduction chemotherapy plus concurrent chemoradiotherapy improved survival outcomes in patients with locally advanced nasopharyngeal carcinoma versus concurrent chemoradiotherapy. For the weekly cisplatin regimen subgroup, it did not improve remote control or overall survival versus concurrent chemoradiotherapy alone, warranting further clarification.

Project description:Concurrent chemoradiotherapy is the established treatment for locally advanced nasopharyngeal carcinoma (NPC). However, there is no evidence supporting routine adjuvant chemotherapy. We aimed to demonstrate the effect of adjuvant chemotherapy on survival and distant metastasis in high-risk N3 NPC patients. We linked the Taiwan Cancer Registry and Cause of Death database to obtain data. Clinical N3 NPC patients were divided as those receiving definitive concurrent chemoradiotherapy (CCRT) with adjuvant 5-fluorouracil and platinum (PF) chemotherapy and those receiving no chemotherapy after CCRT. Patients receiving neoadjuvant chemotherapy were excluded. We compared overall survival, disease-free survival, local control, and distant metastasis in both groups using Cox proportional hazards regression analysis. Propensity-score matching was also performed to evaluate the independent effect of adjuvant PF in a matched cohort with similar baseline characteristics. We included 431 patients (152 and 279 patients in the adjuvant PF and observation groups, respectively). Median follow-up was 4.3 years. The 5-year overall survival were 69.1% and 57.4% in the adjuvant PF chemotherapy and observation groups, respectively (p = 0.02). Adjuvant PF chemotherapy was associated with a lower risk of death (hazard ratio [HR] 0.61, 95% confidence interval [CI] 0.43-0.84; p = 0.003), even after adjusting for baseline prognostic factors (HR 0.61, 95% CI 0.43-0.86; p = 0.005). Distant metastasis-free survival at 12 months was higher in the adjuvant PF chemotherapy group than in the observation group (98% vs 84.8%; p < 0.001). After adjusting for baseline prognostic factors, adjuvant PF chemotherapy was associated with freedom from distant metastasis (HR 0.11, 95% CI 0.02-0.46; p = 0.003). Adjuvant chemotherapy was also associated with a decreased risk of death (HR 0.59, 95% CI 0.41-0.85, p = 0.004) in a propensity score-matched cohort. Prospective evaluation of adjuvant PF chemotherapy in N3 NPC patients treated with definitive CCRT is warranted because adjuvant PF chemotherapy was associated with improved overall survival and decreased risk of distant metastasis.

Project description:PurposeThe aim of this study was to identify the efficacy of diffusion kurtosis imaging (DKI) in tracking and monitoring the dynamic change of parotid glands (PGs), submandibular glands (SMGs), sublingual glands (SLGs), and acute xerostomia in nasopharyngeal carcinoma (NPC) patients treated with induction chemotherapy (IC) plus concurrent chemoradiotherapy (CCRT).MethodsThe prospective study recruited 42 participants treated with IC+CCRT. All patients underwent DKI scanning six times: before IC, before RT, in the middle of the RT course, immediately after RT, and 1 and 3 months post-RT. Mean diffusion coefficient (MD) and mean kurtosis (MK) of PG, SMG, SLG, saliva flow rate measured under resting (uSFR) and stimulated condition (sSFR), and xerostomia questionnaire (XQ) scores were recorded.ResultsAt each time point, sSFR was significantly higher than uSFR (p < 0.05 for all). MD of the salivary glands and XQ scores increased over time while MK, uSFR, and sSFR decreased. After IC, the significant differences were detected in MD and MK of bilateral SMG and MK of the left SLG (p < 0.05 for all), but not in MD and MK of PG, uSFR, sSFR, and XQ scores. After RT, sSFR at 1m-RT decreased significantly (p = 0.03) while no significant differences were detected in uSFR and XQ scores. Moderate-strong correlations were detected in ΔMD-PG-R%, ΔMK-PG-R%, ΔMD-PG-L%, ΔMK-PG-L%, ΔMD-SMG-R%, ΔMK-SMG-R%, ΔMD-SMG-L%, ΔMK-SMG-L%, and ΔMD-SLG-R%, with correlation coefficients (p < 0.05 for all) ranging from 0.401 to 0.714. ΔuSFR% was correlated with ΔMD-SMG% (p = 0.01, r = -0.39), ΔMD-SLG% (p < 0.001, r = -0.532), and ΔMK-SMG% (p < 0.001, r = -0.493). ΔsSFR% correlated with ΔMD-PG% (p = 0.001, r = -0.509), ΔMD-SMG% (p = 0.015, r = -0.221), and ΔMK-PG% (p < 0.001, r = 0.524). ΔXQ% was only correlated with ΔMK-PG% (p = 0.004, r = 0.433).ConclusionDKI is a promising tool for tracking and monitoring the acute damage of PG, SMG, and SLG induced by IC+CCRT in NPC patients.
