Chemoradiotherapy and Subsequent Immunochemotherapy as Conversion Therapy in Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma: A Phase II NEXUS-1 Trial.

Purpose: This phase II trial investigated the safety and efficacy of chemoradiotherapy (CRT) followed by immunochemotherapy (iCT) and surgery in unresectable locally advanced esophageal squamous cell carcinoma (ESCC).

Patients And Methods: Patients with unresectable locally advanced ESCC received radiotherapy (50 Gy/25f, 5 days/week) and nab-paclitaxel (100 mg on day 1/week) plus cisplatin (25 mg/m2 on day 1/week) for 5 weeks, followed by tislelizumab (200 mg on day 1/cycle) plus chemotherapy (nab-paclitaxel 150 mg/m2 and cisplatin 75 mg/m2 on day 2/cycle) for two 21-day cycles. Patients who converted to resectable underwent surgery 2 to 4 weeks afterward.

S-1-based concurrent chemoradiotherapy plus nimotuzumab in patients with locally advanced esophageal squamous cell carcinoma who failed neoadjuvant therapy: a real-world prospective study.

Purpose: This prospective study in a real-world setting investigated the feasibility and safety of S-1 plus nimotuzumab (S-1-Nimo) based concurrent chemoradiotherapy (CCRT) in locally advanced esophageal squamous cell carcinoma (LA-ESCC) patients who failed to neoadjuvant chemotherapy or chemoimmunotherapy.

Methods: LA-ESCC patients who failed to converse to resectable disease after neoadjuvant chemotherapy or chemoimmunotherapy were enrolled to receive the 4-week S-1-Nimo regimen of radiotherapy (40 Gy in 20 fractions, 5 days per week), S-1 chemotherapy, and nimotuzumab. Then, after surgical assessments, patients evaluated as resectable disease received surgery; patients with unresectable disease continued to receive definitive radiotherapy (50-60 Gy in 25-30 fractions, 5 days per week) concurrently with S-1-Nimo.

Conversion chemoradiotherapy combined with nab-paclitaxel plus cisplatin in patients with locally advanced borderline-resectable or unresectable esophageal squamous cell carcinoma: a phase i/ii prospective cohort study.

Background: To evaluate the efficacy and safety of nab-paclitaxel plus cisplatin as the regimen of conversional chemoradiotherapy (cCRT) in locally advanced borderline resectable or unresectable esophageal squamous cell carcinoma (ESCC).

Methods: Patients with locally advanced ESCC (cT3‑4, Nany, M0‑1, M1 was limited to lymph node metastasis in the supraclavicular area) were enrolled. All the patients received the cCRT of nab-paclitaxel plus cisplatin.

Effectiveness and safety of combined nimotuzumab and S-1 chemotherapy with concurrent radiotherapy for locally advanced esophageal cancer in malnourished and elderly patients: A prospective phase II study.

Objective: Definitive chemoradiotherapy (dCRT) is the standard treatment for unresectable locally advanced esophageal cancer. However, this treatment is associated with substantial toxicity, and most malnourished or elderly patients are unable to complete this therapy. Therefore, there is a need for a more suitable radiotherapy combination regimen for this population.

Enhanced thermal activation of persulfate by coupling hydrogen peroxide for efficient degradation of pyrene.

In this study, HO was introduced into thermally activated persulfate oxidation system (T-HPS), and the oxidation of pyrene (PYR) was investigated by the combined T-HPS technology. The results showed that HO could significantly improve the reactivity of the thermally activated persulfate system (T-PS), with 240-min PYR degradation ratio increasing from 79.3% to 97.

[Remediation Performance via the Passivation of a Porous Biomorph Genetic Composite of -FeO/FeO/C Using a Bamboo Template on As(Ⅴ) Contaminated Soils].

Red soil from Guangxi, China was selected as the background soil, and a porous biomorphic genetic composite of -FeO/FeO/C comprising a bamboo template (PBGC-Fe/C) was used as a passivator to remediate As(Ⅴ) contaminated soils. The performance of PBGC-Fe/C was characterized by Scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FT-IR). The results showed that PBGC-Fe/C could improve the passivation effect of As(Ⅴ) from the contaminated soils compared with a single passivation material.
