Impact of preceding treatment for head and neck squamous cell carcinoma on synchronous superficial esophageal squamous cell carcinoma.

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
backgroundPatients with esophageal squamous cell carcinoma (ESCC) frequently develop synchronous head and neck squamous cell carcinoma (HNSCC). With advances in endoscopic technology and widespread screening of synchronous cancers, the detection of synchronous HNSCC and superficial ESCC (SESCC) is increasing. We aimed to evaluate the impact of preceding HNSCC treatment on synchronous SESCC.
methodsThis single-center retrospective study enrolled patients with synchronous HNSCC and SESCC who were treated between January 2010 and December 2023. Tumor size and depth of SESCC before and after HNSCC treatment were evaluated. The factors associated with SESCC progression were investigated.
resultsOf the 299 patients with synchronous HNSCC and SESCC, 134 who underwent preceding HNSCC treatment with follow-up esophagogastroduodenoscopy (EGD) for SESCC were evaluated. Chemoradiotherapy was the most common treatment for HNSCC (56.0%), followed by surgery (17.2%), radiotherapy (14.9%), local resection (7.5%), and chemotherapy (4.5%). The tumor size of SESCC increased after HNSCC treatment in 18 patients (13.4%). Multivariate analysis revealed that an EGD interval of ≥ 120 days was significantly associated with increased tumor size in SESCC (odds ratio, 6.64; 95% confidence interval, 1.91-23.1). Tumor regrowth was observed in 70.6% of SESCCs that shrank with HNSCC treatment, mostly within six months. Tumor depth aggravation was rare (2.2%), but progression to advanced ESCC was observed in two patients.
conclusionsTimely endoscopic follow-up, preferably within 120 days, is crucial for managing synchronous SESCC after HNSCC treatment to prevent tumor progression. Tumor regrowth should be monitored when SESCC shrinks with HNSCC treatment.
