Risk Stratification in T4 or N3 Nasopharyngeal Carcinoma.
Article in Cancer research and treatment, 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
purposeThis study aimed to investigate the prognostic heterogeneity among stage III nasopharyngeal carcinoma (NPC) patients according to the 9th edition of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) staging system to identify potential subgroups requiring tailored therapeutic strategies. MATERIALS AND
methodsWe retrospectively included stage III patients (T1-3N3 or T4N0-3) who were diagnosed with NPC between January 2015 and December 2021 according to the 9th edition of the AJCC/UICC staging system. Kaplan-Meier method and multivariable Cox regression analyses were used for statistical analysis.
resultsA total of 309 patients were included in this study. A total of 92/309 (29.8%) patients developed locoregional recurrence and/or distant metastasis with a median follow-up of 52.9 months. Those with T4N3 disease had significantly lower distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) but comparable locoregional relapse-free survival (LRFS) to those with T1-3N3 and T4N0-2 disease. Those with T4N3 disease had comparable LRFS but significantly lower 5-year DMFS (78.7% vs. 44.7%, p < 0.001), PFS (65.7% vs. 27.6%, p < 0.001), and OS (77.1% vs. 45.9%, p < 0.001) compared to those with stage T4N0-2 and T1-3N3 diseases. Similar results were confirmed using the multivariate analysis.
conclusionOur study demonstrates the prognostic heterogeneity of stage III disease within the 9th edition NPC staging system. T4N3 category should be considered separately and treated as a distinct entity regardless of the staging editions.
