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

Distant metastasis is an important prognostic factor for oral squamous cell carcinoma (OSCC). It involves the direct spread of tumor cells through blood vessels or via lymph nodes; however, there are currently no well-established treatments for its prevention in patients with OSCC. To investigate the impact of metronomic neoadjuvant chemotherapy on OSCC, we conducted a retrospective analysis of the efficacy of neoadjuvant chemotherapy with S-1 alone. Fifty-four patients underwent up-front surgery, while 106 received neoadjuvant chemotherapy with S-1 alone. A serious adverse event occurred in one of patient treated with neoadjuvant chemotherapy (1%); however, all patients underwent resection. The 5-year overall survival rate was higher with S-1 than with up-front surgery (96% vs. 81%, P = 0.002). Moreover, neoadjuvant chemotherapy significantly increased the overall survival rate of patients with poorly or moderately differentiated tumors, but not those with well-differentiated tumors. By analyzing a cohort of 523 head and neck squamous cell carcinoma (HNSCC) patients in the Cancer Genome Atlas, we identified genetic variants associated with histological differentiation. The frequency of pathogenic/likely pathogenic variants or deletions in 5 genes associated with HNSCC correlated with histological differentiation, some of which indicated the activation of the Wnt/β-catenin pathway in well-differentiated HNSCC. The vessel marker CD31 was highly expressed in poorly differentiated OSCC, whereas the anti-angiogenic molecule, LCN2, which is induced by the activation of the Wnt pathway, was highly expressed in well-differentiated OSCC. The present study showed that overall survival rates were higher in patients with poorly or moderately differentiated OSCC who received metronomic neoadjuvant chemotherapy, which was attributed to a difference in angiogenesis based on the characteristic landscape of pathogenic mutations according to histological differentiation.
