1 · What the graph read from it

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.

2 · The registry

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 evaluate the long-term outcome and toxicities in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) treated by concurrent chemoradiotherapy (CCRT) with/without adding cetuximab.

methodsA total of 62 patients treated with CCRT plus cetuximab were matched with 124 patients treated with CCRT alone by age, sex, pathological type, T category, N category, disease stage, radiotherapy (RT) technique, Epstein-Barr virus (EBV) DNA levels, and Eastern Cooperative Oncology Group (ECOG). Overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were assessed using the Kaplan-Meier method and log-rank test. Treatment toxicities were clarified and compared between two groups.

resultsA total of 186 well-balanced stage II to IV NPC patients were retrospectively analyzed (median follow-up, 76 months). Compared to CCRT alone, adding cetuximab resulted in more grade 3 to 4 radiation mucositis (51.6% vs. 23.4%; P < 0.001). No differences were found between the CCRT + cetuximab group and the CCRT group in 5-year OS (89.7% vs. 90.7%, P = 0.386), 3-year PFS (83.9% vs. 88.7%, P = 0.115), the 3-year LRFS (95.0% vs. 96.7%, P = 0.695), and the 3-year DMFS (88.4% vs 91.9%, P = 0.068). Advanced disease stage was the independent prognostic factor predicting poorer OS and PFS.

conclusionAdding cetuximab to CCRT did not significantly improve benefits in survival in stage II to IV NPC and exacerbated acute mucositis and acneiform rash. Further investigations are warranted.
