The role of neoadjuvant therapy in elderly patients with T1b-T2N + esophageal cancer: a population-based cohort study.
Article in Discover oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundStudies regarding whether elderly patients (≥ 70 years) with T1b-T2N + esophageal cancer (EC) could benefit from neoadjuvant therapy (NAT) are lacking. Therefore, the aim of this study was to investigate the impact of NAT on the outcomes of elderly patients with T1b-T2N + EC.
methodsPatients aged ≥ 70 years with stage T1b-T2N + M0 EC who underwent surgery were identified within the SEER database (2004-2019). Propensity score matching (PSM) was used to equalize differences between the NAT and non-NAT groups. Kaplan-Meier analysis and Cox proportional hazards models were used to assess the differences between groups in terms of overall survival (OS) and cancer-specific survival (CSS).
resultsAfter PSM, 180 elderly patients with T1b-T2N + EC were included, which achieved a balanced distribution between groups. The 3-year OS (55.6% vs. 33.1%, P = 0.013) and CSS (62.3% vs. 39.0%, P = 0.012) rates of the NAT group were significantly better than those of the non-NAT group. Multivariate Cox regression analysis demonstrated that NAT was an independent protective prognostic factor for OS (HR, 0.650; 95% CI 0.462-0.915; P = 0.014) and CSS (HR, 0.591; 95% CI 0.369-0.883; P = 0.010). In addition, subgroup analysis revealed NAT was associated with survival benefits in several subgroups, including females, white race, those with middle/upper esophageal tumors, squamous cell carcinoma, tumor size < 3 cm, examined lymph nodes < 15, and T2-stage disease.
conclusionCompared with upfront surgery, NAT was associated with a survival benefit in elderly patients with stage T1b-2 N + EC.
