First-line immune checkpoint inhibitors in older adults (≥75 years) with advanced esophageal squamous cell carcinoma: efficacy and safety.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The combination of immune checkpoint inhibitors with chemotherapy is a standard first-line treatment for advanced esophageal squamous cell carcinoma. However, robust data regarding the efficacy and safety of this approach specifically in patients aged 75 years and older are scarce, as this population is frequently underrepresented in pivotal clinical trials. Objective: This study aimed to evaluate the real-world treatment outcomes and safety profile of first-line immunotherapy in patients aged ≥75 years with advanced esophageal squamous cell carcinoma. Methods: We conducted a retrospective, single-center cohort study. Sixty-one patients aged ≥75 years with histologically confirmed, advanced esophageal squamous cell carcinoma (stage III/IV) who initiated first-line immune checkpoint inhibitors (as monotherapy or combined with chemotherapy/antiangiogenic therapy) between February 2021 and May 2025 were included. Assessments included tumor response per RECIST 1.1, progression-free survival, overall survival, and adverse events graded per the National Cancer Institute Common Toxicity Criteria v5.0. Results: The median age was 80 years. The objective response rate was 45.9% (28/61), and the disease control rate was 85.2%. After a median follow-up of 16.7 months, the median progression-free survival was 12.7 months (95% CI: 6.9-17.1), and the median overall survival was 17.7 months (95% CI: 10.7-22.8). Both progression-free survival and overall survival significantly differed among response groups (log-rank Conclusion: In this real-world cohort, first-line immunotherapy demonstrated promising efficacy and a manageable safety profile in patients aged ≥75 years with advanced esophageal squamous cell carcinoma. These findings provide valuable preliminary evidence supporting the use of immune checkpoint inhibitors in this understudied population and highlight the need for prospective validation to optimize therapeutic strategies.
