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

Tyrosine kinase inhibitors (TKIs) were first approved for treating radioactive iodine-refractory differentiated thyroid cancer (DTC) and anaplastic thyroid cancer (ATC) 5 years ago. Among them, lenvatinib has a high response rate and has become the first-line drug for treating thyroid cancer. Although it has a high response rate, it is also characterized by a high frequency of adverse events (AEs). AEs previously reported in a phase II study occurred after the practical application of TKI therapy. However, the type and frequency of AEs that occurred were significantly different. The present study investigated the type and frequency of AEs in the real-world setting and examined their relationship with prognosis. Between June 2015 and May 2020, 111 patients (79 patients with DTC and 32 patients with ATC) were treated with lenvatinib. An investigation of lenvatinib AEs, including fatal events, revealed that fistula formation or severe tumor regrowth after the discontinuation of treatment was an AE associated with poor prognosis. In total, 11 patients with ATC (34.4%) and 7 patients with DTC (8.9%) developed skin fistula. The mortality rate among these patients was 38.9% (7/18), including three deaths caused by major bleeding and four deaths attributable to mediastinitis or pneumonia. In the DTC group, irreversible regrowth occurred in all 7 patients who required drug withdrawal because of AEs, and all patients died. Conversely, overall survival was longer among patients with DTC and hand-foot syndrome (HFS). Therefore, the present study illustrated that although lenvatinib therapy can result in severe AEs requiring dose reduction or treatment discontinuation, the HFS appearance portends a good prognosis in patients treated with lenvatinib.
