Abstract
IMPORTANCE Multiple paclitaxel-based regimens are widely used in chemoradiation therapy against esophageal cancer, including regimens combining paclitaxel with fluorouracil, cisplatin, and carboplatin. However, which among these 3 regimens provides the best prognosis with minimum adverse events is still unknown. OBJECTIVE To compare the efficacy and adverse events of fluorouracil, cisplatin, and carboplatin in definitive chemoradiotherapy in patients with esophageal squamous cell carcinoma (ESCC). DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial of patients with ESCC was conducted in 11 treatment centers in China. Eligible patients were aged 18 to 75 years and had histologically confirmed ESCC stages IIa to IVa with no prior treatment, Eastern Cooperative Oncology Group performance status of 2 or lower, and adequate organ functions. The study was conducted between July 2015 and February 2018, and the cutoff date for data analysis was August 31, 2020. INTERVENTIONS Patients with locally advanced ESCC were randomly assigned (1:1:1) to groups combining paclitaxel treatment with fluorouracil, cisplatin, or carboplatin. Patients in the cisplatin group were treated with 2 cycles of concurrent chemoradiotherapy followed by 2 cycles of consolidation chemotherapy with monthly paclitaxel plus cisplatin. For the fluorouracil group, patients were administered 6 cycles of weekly paclitaxel plus fluorouracil in concurrent chemoradiotherapy followed by 2 cycles of monthly paclitaxel plus fluorouracil in consolidation chemotherapy. Patients in the carboplatin group were treated with 6 cycles of weekly paclitaxel plus carboplatin in concurrent chemoradiotherapy followed by 2 cycles of monthly paclitaxel plus carboplatin in consolidation chemotherapy. All patients received radiotherapy of 61.2 Gy delivered in 34 fractions. MAIN OUTCOMES AND MEASURES The primary end point was overall survival (OS). The secondary end points were progression-free survival and adverse events. RESULTS Overall, 321 patients (median [IQR] age, 64 years [59-69 years]; 248 [77.3%] men) with ESCC from 11 centers were randomized into fluorouracil, cisplatin, or carboplatin groups between July 2015 and February 2018. Over a median (IQR) follow-up time of surviving patients of 46.0 months (36.6-53.0 months), the 3-year OS rates were 57.2% in the fluorouracil group, 60.1% in the cisplatin group, and 56.5% in the carboplatin group, respectively (fluorouracil vs cisplatin: HR, 1.06; 95% CI, 0.71-1.60; P = .77; fluorouracil vs carboplatin: HR, 0.94; 95% CI, 0.63-1.40; P = .77). The cisplatin group had significantly higher incidences of acute grade 3 or 4 neutropenia (69 events [60.8%] vs 19 [17.8%] for fluorouracil and 37 [34.6%] carboplatin; P < .001), thrombocytopenia (14 events [13.1%] vs 4 [3.7%] for fluorouracil and 5 [4.7%] for carboplatin; P = .01), anemia (50 events above grade 2 [46.7%] vs 25 [23.4%] for fluorouracil and 37 [34.6%] for carboplatin; P = .35), fatigue (11 events [10.3%] vs 2 [1.9%] for fluorouracil and 1 [0.9%] carboplatin; P = .007), and vomiting (17 events above grade 2 [15.9%] vs 3 [2.8%] for fluorouracil and 5 [4.7%] for carboplatin; P < .001) than the other 2 groups. CONCLUSIONS AND RELEVANCE In this randomized clinical trial, paclitaxel plus fluorouracil did not show OS superiority over paclitaxel plus cisplatin or paclitaxel plus carboplatin regimens in definitive chemoradiation in patients with locally advanced ESCC. Higher rates of hematologic and gastrointestinal toxic effects were reported in the cisplatin group compared with those in the fluorouracil or carboplatin groups. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02459457.

Int J Nanomedicine 2020; 15:7745-7762. [PMID: 33116498 PMCID: PMC7553263 DOI: 10.2147/ijn.s257312] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Accepted: 09/16/2020] [Indexed: 12/16/2022] Open
Abstract
Background Although single-drug chemotherapy is still an effective treatment for esophageal cancer, its long-term application is limited by severe side-effects, poor bioavailability, and drug-resistance. Increasing attention has been paid to nanomedicines because of their good biological safety, targeting capabilities, and high-efficiency loading of multiple drugs. Herein, we have developed a novel T7 peptide-modified pH-responsive targeting nanosystem co-loaded with docetaxel and curcumin for the treatment of esophageal cancer. Methods Firstly, CM-β-CD-PEI-PEG-T7/DTX/CUR (T7-NP-DC) was synthesized by the double emulsion (W/O/W) method. The targeting capacity of the nanocarrier was then investigated by in vitro and in vivo assays using targeted (T7-NP) and non-targeted nanoparticles (NP). Furthermore, the anti-tumor efficacy of T7-NP-DC was studied using esophageal cancer cells (KYSE150 and KYSE510) and a KYSE150 xenograft tumor model. Results T7-NP-DC was synthesized successfully and its diameter was determined to be about 100 nm by transmission electron microscopy and dynamic light scattering. T7-NP-DC with docetaxel and curcumin loading of 10% and 6.1%, respectively, had good colloidal stability and exhibited pH-responsive drug release. Good biosafety was observed, even when the concentration was as high as 800 μg/mL. Significant enhancement of T7-NP uptake was observed 6 hours after intravenous injection compared with NP. In addition, the therapeutic efficacy of T7-NP-DC was better than NP-DC and docetaxel in terms of growth suppression in the KYSE150 esophageal cancer model. Conclusion The findings demonstrated that T7-NP-DC is a promising, non-toxic, and controllable nanoparticle that is capable of simultaneous delivery of the chemotherapy drug, docetaxel, and the Chinese Medicine, curcumin, for treatment of esophageal cancer. This novel T7-modified targeting nanosystem releases loaded drugs when exposed to the acidic microenvironment of the tumor and exerts a synergistic anti-tumor effect. The data indicate that the nanomaterials can safely exert synergistic anti-tumor effects and provide an excellent therapeutic platform for combination therapy of esophageal cancer.
