Simultaneous concurrent chemoradiotherapy and esophagectomy for synchronous head and neck and esophageal squamous cell carcinoma: a retrospective review.
Article in Radiation oncology (London, England), 2025. 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
backgroundThis study aimed to assess the clinical outcomes and prognostic factors of patients with synchronous head and neck squamous cell carcinoma (HNSCC) and esophageal squamous cell carcinoma (ESCC) who underwent simultaneous concurrent chemoradiotherapy (CCRT) and esophagectomy.
methodsThirty-one patients who underwent simultaneous CCRT for synchronous HNSCC and ESCC were retrospectively reviewed. The treatment strategy involved simultaneous definitive CCRT at 70 Gy/35 fractions for HNSCC and neoadjuvant CCRT at 48 Gy/24 fractions for ESCC. Esophagectomy was evaluated 4-5 weeks after neoadjuvant CCRT. The radiotherapy plan utilized a simultaneously integrated boost technique at 4-5 dose levels. Patients received weekly platinum chemotherapy during CCRT. Patient characteristics, treatment responses, and survival rates were analyzed. Survival analysis was conducted using the Kaplan-Meier method and Cox regression analyses.
resultsAll the patients completed CCRT at the planned doses and radiation fields with a good tolerance profile. The 1- and 2-year survival rates were 62.9% and 34.4%, respectively. Performance status (PS), ESCC tumor location, HNSCC clinical stage, and clinical responses of HNSCC and ESCC, both individually and combined, were significantly associated with prognosis. PS and the clinical response of ESCC were significant predictors of overall survival. Adverse effects were manageable, with up to eleven patients (35.5%) developing grade 3/4 neutropenia. No treatment-related mortality was noted.
conclusionsThe treatment strategy using simultaneous definitive CCRT for HNSCC and neoadjuvant CCRT for ESCC followed by esophagectomy for synchronous HNSCC and ESCC is effective and well-tolerated. PS and clinical response of ESCC are significant prognostic factors for this treatment strategy.
