Objective: Esophageal cancer (EC) ranks eighth among cancers in cancer-related deaths globally, and ~44% of new cases occur in China. We sought to describe the clinical characteristics and treatment landscape of EC in China before the approval of immunotherapy in 2020.  \nMethods: CHANNEL was a large, retrospective study using patient-level data from 14 hospitals/cancer centers across China, including adults initiating therapy for newly diagnosed EC (January to December 2018) . Demographics, clinicopathologic characteristics, and treatment patterns over 6 months were descriptively summarized.  \nResults: Of 3,493 patients, 75.7% were men, the mean age was 64.1 years, and 75.0% had no family history of cancer. Most (92.8%) had squamous cell carcinoma, with a primary lesion in the middle esophagus (56.4%). Among patients with resectable EC, 92.9% received initial surgery, and 7.1% received neoadjuvant therapy, primarily chemotherapy (85.5% platinum-taxane). Among patients with unresectable early or locally advanced EC, 50.8% and 49.2% received palliative and radical therapy, respectively, as the initial treatment, primarily chemotherapy (66.5% platinum-taxane) and chemoradiotherapy (50.8% platinum-taxane), respectively. Adjuvant therapy was administered to 22.9% of patients undergoing initial surgery, and 2.4% receiving neoadjuvant therapy and surgery. Among patients with advanced EC, 84.6% received systemic therapy as an initial treatment, primarily chemotherapy (61.5% platinum-taxane) .  \nConclusions: Before the approval of immunotherapy in China, most patients with resectable early or locally advanced EC underwent ","cbCaieRBPYqEPPIi","https://ap.wps.com/l/cbCaieRBPYqEPPIi","pdf",238133,14,"English","# Introduction\n## Clinical management and pre-immunotherapy context\n# Abstract\n## Objective\n## Methods\n## Results\n## Conclusions","[{\"question\":\"What is the main objective of this study?\",\"answer\":\"To characterize clinical features and describe treatment patterns for esophageal cancer patients in China before immunotherapy approval in 2020.\"},{\"question\":\"What dataset and time period were used in the retrospective analysis?\",\"answer\":\"The CHANNEL study used patient-level data from 14 hospitals/cancer centers, including adults initiating therapy for newly diagnosed esophageal cancer between January and December 2018.\"},{\"question\":\"How did initial treatments differ across resectable versus unresectable cases?\",\"answer\":\"For resectable disease, most patients received initial surgery, while unresectable early or locally advanced patients mainly received palliative or radical therapy, with chemotherapy and chemoradiotherapy featuring prominently.\"}]","Retrospective analysis of disease characteristics and treatment patterns among patients with esophageal cancer across 14 surgically represented centers | PDF",1790191490,35]
