Development of a prognostic nomogram and risk stratification system for elderly patients with esophageal squamous cell carcinoma undergoing definitive radiotherapy: a multicenter retrospective analysis (3JECROG R-03 A).

Background: Our goal is to develop a nomogram model to predict overall survival (OS) for elderly esophageal squamous cell carcinoma (ESCC) patients receiving definitive radiotherapy (RT) or concurrent chemoradiotherapy (CRT), aiding clinicians in personalized treatment planning with a risk stratification system.

Methods: A retrospective study was conducted on 718 elderly ESCC patients treated with RT or CRT at 10 medical centers (3JECROG) from January 2004 to November 2016. We identified independent prognostic factors using univariate and multifactorial Cox regression to construct a nomogram model.

Immunochemotherapy plus radiotherapy versus immunochemotherapy alone as first-line treatment for treatment-naïve, advanced esophageal squamous cell carcinoma (AEC-ICR-1st): A multi-center cohort study.

Immunochemotherapy is Currently the standard first-line treatment for advanced esophageal squamous cell carcinoma (ESCC). However, its prognosis remains unsatisfactory. We aimed to evaluate the efficacy and safety of immunochemotherapy plus radiotherapy (ICR) compared with immunochemotherapy (IC) alone as a first-line treatment for advanced ESCC.

Multimodality deep learning radiomics predicts pathological response after neoadjuvant chemoradiotherapy for esophageal squamous cell carcinoma.

Objectives: This study aimed to develop and validate a deep-learning radiomics model using CT, T2, and DWI images for predicting pathological complete response (pCR) in patients with esophageal squamous cell carcinoma (ESCC) undergoing neoadjuvant chemoradiotherapy (nCRT).

Materials And Methods: Patients with ESCC undergoing nCRT followed by surgery were retrospectively enrolled from three institutions and divided into training and testing cohorts. Both traditional and deep-learning radiomics features were extracted from pre-treatment CT, T2, and DWI.

TQB2450 with or without anlotinib as maintenance treatment in subjects with locally advanced/unresectable non-small cell lung cancer that have not progressed after prior concurrent/sequential chemoradiotherapy (R-ALPS): study protocol for a randomized, double-blind, placebo-controlled, multicenter phase III trial.

Background: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of non-small cell lung cancer (NSCLC). TQB2450 (benmelstobart) is a novel humanized immunoglobulin G1 monoclonal antibody against programmed death-ligand 1 (PD-L1). Anlotinib, an oral multitargeted anti-angiogenic agent with potential synergy with ICIs, has shown efficacy in relapsed and advanced NSCLC.

Optimization of radiation target volume for locally advanced esophageal cancer in the immunotherapy era.

Introduction: Locally advanced esophageal cancer (EC) has poor prognosis. Preliminary clinical studies have demonstrated the synergistic efficacy of radiotherapy combined with immunotherapy in EC. Adjusting the radiotherapy target volume to protect immune function favors immunotherapy.

Survival benefit and spatial properties of tertiary lymphoid structures in esophageal squamous cell carcinoma with neoadjuvant therapies.

Tertiary lymphoid structures (TLSs) were associated with survival in esophageal squamous cell carcinoma (ESCC) undergoing surgery alone (SA). However, their clinical relevance in neoadjuvant therapies remains less known. Here, we firstly investigated the presence, maturation and spatial distribution of TLSs in 359 ESCC patients receiving neoadjuvant chemotherapy (NCT), neoadjuvant immunotherapy (NCI), neoadjuvant chemoradiotherapy (NCRT) or SA.

Neoadjuvant chemoimmunotherapy was associated with better short-term survival of patients with locally advanced esophageal squamous cell carcinoma compared to neoadjuvant chemoradiotherapy.

Introduction: The chemotherapy and immunotherapy combination is currently the primary strategy to treat metastatic esophageal squamous cell carcinoma (ESCC). Neoadjuvant chemoimmunotherapy (NCIT) is being intensively investigated for treating locally advanced ESCC.

Objective: We compared the efficacy and safety of NCIT and neoadjuvant chemoradiotherapy (NCRT) to treat locally advanced ESCC.

Two distinct age-prognosis patterns in patients with esophageal cancer undergoing surgical and radiotherapy treatments: a combined analysis of 3JECROG and SEER databases.

Background: Age is a known prognostic factor for various cancers. However, few studies explored the association between age and prognosis of esophageal cancer (EC) comprehensively, especially from a nonlinear perspective.

Design: Retrospective cohort study.

Treatment-related pneumonitis after thoracic radiotherapy/chemoradiotherapy combined with anti-PD-1 monoclonal antibodies in advanced esophageal squamous cell carcinoma.

Purpose: This study aims to evaluate the risk factors of treatment-related pneumonitis (TRP) following thoracic radiotherapy/chemoradiotherapy combined with anti-PD‑1 monoclonal antibodies (mAbs) in patients with advanced esophageal squamous cell carcinoma (ESCC).

Methods: We retrospectively reviewed 97 patients with advanced ESCC who were treated with thoracic radiotherapy/chemoradiotherapy combined with anti-PD‑1 mAbs. Among them, 56 patients received concurrent radiotherapy with anti-PD‑1 mAbs and 41 patients received sequential radiotherapy with anti-PD‑1 mAbs.

Adding simultaneous integrated boost to whole brain radiation therapy improved intracranial tumour control and minimize radiation-induced brain injury risk for the treatment of brain metastases.

Background: Brain metastases (BMs) are the most frequent intracranial tumours associated with poor clinical outcomes. Radiotherapy is essential in the treatment of these tumours, although the optimal radiation strategy remains controversial. The present study aimed to assess whether whole brain radiation therapy with a simultaneous integrated boost (WBRT + SIB) provides any therapeutic benefit over WBRT alone.

Predictive and prognostic markers from endoscopic ultrasound with biopsies during definitive chemoradiation therapy in esophageal squamous cell carcinoma.

Introduction: Endoscopic ultrasound (EUS) may play a role in evaluating treatment response after definitive chemoradiation therapy (dCRT) for esophageal squamous cell carcinoma (ESCC). This study explored the prognostic markers of EUS with biopsies and developed two nomograms for survival prediction.

Methods: A total of 821 patients newly diagnosed with ESCC between January 2015 and December 2019 were reviewed.

Spatial distribution of tumor-infiltrating T cells indicated immune response status under chemoradiotherapy plus PD-1 blockade in esophageal cancer.

Background: The spatial distribution of tumor-infiltrating T cells and its dynamics during chemoradiotherapy combined with PD-1 blockade is little known in esophageal squamous cell carcinoma (ESCC).

Methods: We applied the multiplex immunofluorescence method to identify T cells (CD4, CD8 T cells, and their PD-1 or PD-1 subsets) and myeloid-derived cells (CD11c dendritic cells, CD68 macrophages, and their PD-L1 subpopulations) in paired tumor biopsies ( = 36) collected at baseline and during combination (40 Gy of radiation) from a phase Ib trial (NCT03671265) of ESCC patients treated with first-line chemoradiotherapy plus anti-PD-1 antibody camrelizumab. We used the FoundationOne CDx assay to evaluate tumor mutational burden (TMB) in baseline tumor biopsies ( = 14).

Effectiveness of S-1-Based Chemoradiotherapy in Patients 70 Years and Older With Esophageal Squamous Cell Carcinoma: A Randomized Clinical Trial.

Importance: Double-agent intravenous chemotherapy concurrent with radiotherapy is the standard of care for patients with inoperable esophageal cancer. However, patients tend to tolerate intravenous chemotherapy less well with age and comorbidities. It is essential to find a better treatment modality that improves survival outcomes without reducing the quality of life.

Effects of PEG in patients with esophageal squamous cell carcinoma during concurrent chemoradiotherapy: a prospective study.

Background And Aims: This prospective study aimed to compare the changes in nutritional status and adverse events among patients with esophageal squamous cell carcinoma who received enteral nutrition through oral intake, PEG, and an enteral nasogastric tube (NGT) during concurrent chemoradiotherapy (CCRT).

Methods: Of 141 included patients, 38, 74, and 29 patients were fed through oral intake, PEG, and NGTs, respectively. The clinical characteristics and baseline nutritional status of the 3 groups were recorded and analyzed.

Radiotherapy plus camrelizumab affects peripheral CD8 T-cell differentiation subsets expressing PD-1, TIGIT, and CTLA-4 in esophageal squamous cell carcinoma.

Our previous phase Ib trial (NCT03222440) showed that radiotherapy plus the anti-PD-1 antibody camrelizumab is a safe and feasible first-line therapy for locally advanced esophageal squamous cell carcinoma. In this study, we divided peripheral CD8 T-cell differentiation subsets into 4 subpopulations (naive T cells, central memory T cells, effector memory T cells, and CD45RA+ effector memory T cells). We then investigated the influence of radiotherapy plus camrelizumab therapy on the proportions of the 4 subsets and their PD-1, TIGIT, and CTLA-4 expression as well as their proliferative activity and compared the effects with those of concurrent chemoradiotherapy.

Comparison of dynamic changes in the peripheral CD8 T cells function and differentiation in ESCC patients treated with radiotherapy combined with anti-PD-1 antibody or concurrent chemoradiotherapy.

Objective: The systematic immune status of cancer patients undergoing immunotherapy is little known. We prospectively identified the function and differentiation traits of peripheral CD8 T cells based on our phase 1b clinical trial (NCT03222440) of radiotherapy combined with camrelizumab in patients with locally advanced esophageal squamous cell carcinoma (ESCC) and compared it with concurrent chemoradiotherapy (CCRT).

Methods: 19 and 18 patients were included in the cohort of radiotherapy plus camrelizumab and cohort of CCRT treatment.

Prognostic values of the gross volume of metastatic lymph nodes in patients with esophageal squamous cell carcinoma treated with definitive concurrent chemoradiotherapy.

Purpose: We aim to explore whether the gross volume of metastatic lymph nodes (GTVnd) and the gross volume of primary tumor (GTVp) could be prognostic factors for esophageal squamous cell carcinoma (ESCC) patients treated with definitive concurrent chemoradiotherapy (dCCRT).

Methods: We retrospectively analyzed 252 ESCC patients treated with dCCRT in the era of intensity-modulated radiation therapy (IMRT) at our institution. The cut-off value for the GTVnd derived from the restricted cubic splines (RCS) was determined.
