Efficacy of adjuvant chemotherapy on overall survival in patients with lymph node-positive esophageal squamous cell carcinoma: Is oral chemotherapy promising?
Article in Cancer medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe role of adjuvant chemotherapy in patients with pathological lymph node-positive (pN+) resectable esophageal squamous cell carcinoma (ESCC) remains unclear. We aimed to explore whether adjuvant chemotherapy could improve the overall survival (OS) of patients with pN+ ESCC and whether oral chemotherapy could be used as an alternative to intravenous chemotherapy.
methodsThe patients were divided into two groups: a surgery plus chemotherapy group (S + CT group, 400 patients) and a surgery alone group (S group, 582 patients). Propensity score matching (PSM) was used to create patient groups that were balanced across several covariates (n = 331 in each group). The survival rates of patients receiving oral chemotherapy (69 patients with S-1 and 68 patients with tegafur tablets) and intravenous chemotherapy (263 patients) were compared using the Kaplan-Meier method.
resultsIn the overall study cohort, the 3-year OS was significantly higher in the S + CT group than in the S group (66.3% vs. 49.9%, p < 0.001). These data were confirmed in the matched groups (3-year OS, 72.9% vs. 62.0%, p < 0.001). Multivariate Cox regression analysis in the matched samples showed that adjuvant chemotherapy was an independent prognostic factor for ESCC (HR: 0.62, 95% CI: 0.50-0.76, p < 0.001). Patients who received oral chemotherapy had a similar OS as patients who received intravenous chemotherapy.
conclusionsAdjuvant chemotherapy could significantly improve the OS of patients with pN+ ESCC, and oral chemotherapy drugs might be a better option because of their similar efficacy but fewer side effects than intravenous chemotherapy. This conclusion warrants further study in prospective, randomized controlled trials.
