Radiotherapy with or without chemotherapy for T2N0 hypopharyngeal cancer: an analysis of the head and neck cancer registry of Japan.
Article in International journal of clinical 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
purposeThis retrospective study compared the outcomes of radiotherapy (RT) and chemoradiotherapy (CRT) in patients with T2N0 hypopharyngeal cancer.
methodsWe analyzed patients with T2N0 hypopharyngeal squamous cell carcinoma treated with RT or CRT between 2011 and 2016 using data from the Head and Neck Cancer Registry of Japan.
resultsAmong 53,512 patients, 457 with T2N0 disease received RT (n = 165) or CRT (n = 292; median follow-up, 41.8 months; median age, 70 years). Tumor sites included the pyriform sinus (72.9%), postcricoid region (12.3%), posterior wall (11.8%), and unknown (3.1%). The groups differed in terms of age and alcohol use. Before weighing, CRT was associated with longer PFS and a lower cumulative incidence of locoregional recurrence compared with RT. However, in the IPTW-adjusted analysis, CRT did not significantly improve OS (hazard ratio [HR], 0.98; 95% confidence interval [CI], 0.59-1.62) or PFS (HR, 0.79; 95% CI, 0.53-1.16) compared with RT. PFS was associated with alcohol/smoking history, performance status, and primary site of the tumor.
conclusionIn T2N0 hypopharyngeal cancer, CRT reduced the locoregional recurrence compared to RT. However, CRT did not confer a significant OS or PFS advantage over RT after adjustment for baseline imbalances. RT alone may, therefore, be a reasonable definitive treatment option for selected patients.
