Preliminary clinical outcomes of head and neck squamous cell carcinoma treated with particle beam radiation therapy.
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
purposeFurther improvement in clinical outcomes is needed for patients with head and neck squamous cell carcinoma (HNSCC), as there is typically a poor prognosis at diagnosis. This study aimed to report the preliminary therapeutic outcomes and side effects in patients with HNSCC receiving particle beam radiotherapy (PBRT), owing to the physical and biological advantages of this approach.
methodsWe retrospectively analyzed 68 patients with newly diagnosed HNSCC who received PBRT at the Shanghai Proton and Heavy Ion Center (SPHIC) between August 2015 and December 2020. The Kaplan-Meier approach was used to determine overall survival (OS), disease-specific survival (DSS), progression-free survival (PFS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), and distant metastasis-free survival (DMFS). Common Terminology Criteria for Adverse Events (CTCAE) 4.03 was also used to grade acute and late toxicities.
resultsWith a median follow-up time of 24.5 months (range, 3-65), the 3-year OS, DSS, PFS, LRFS, RRFS, and DMFS rates for the entire cohort were 79.0%, 84.7%, 67.9%, 83.5%, 83.3%, and 96.1%, respectively. Univariate and multivariate analyses showed that N category was a significant predictor of OS, PFS, and RRFS. In terms of acute toxicities, two patients demonstrated severe mucositis or dysphagia, and two patients also displayed a late toxicity of significant mucosal necrosis.
conclusionThese findings suggest that PBRT can provide patients with HNSCC with a promising therapeutic benefit and manageable toxicity. Prospective evaluation of clinical outcomes with PBRT for HNSCC is warranted, with an emphasis on clinical effectiveness as well as adverse effects and patient quality of life.
