Lenvatinib for large hepatocellular carcinomas with portal trunk invasion: Two case reports.
Article in World journal of clinical cases, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn a phase III trial of lenvatinib as first-line treatment for advanced unresectable hepatocellular carcinoma (uHCC), the drug proved non-inferior to sorafenib in terms of the overall survival, but offered better progression-free survival. However, the effects of lenvatinib in uHCC patients with a tumor thrombus in the main portal vein and/or a high tumor burden (tumor occupancy more than 50% of the total liver volume), remain unclear, because these were set as exclusion criteria in the aforementioned trial. CASE SUMMARY: A 53-year-old man (case 1) and 66-year-old woman (case 2) with uHCC presented to us with a tumor thrombus in both the main portal vein and inferior vena cava, a high tumor burden accompanied by a tumor diameter greater than > 100 mm, and distant metastasis, with the residual liver function classified as grade 2A according to the modified Albumin-Bilirubin grading. We started both patients on lenvatinib. The therapeutic effect, as evaluated by the modified Response Evaluation Criteria in Solid Tumors, was rated as partial response in both case 1 and case 2 (at 8 wk and 4 wk after the start of lenvatinib administration, respectively). The therapeutic effect was sustained for 6 mo in case 1 and 20 mo in case 2. Fever occurred as an adverse event in both case 1 and 2, and hyperthyroidism and thrombocytopenia in only case 2, neither of which, however, necessitated treatment discontinuation.
conclusionEven in hepatocellular carcinoma patients with poor prognostic factors, if the liver function is well-preserved, lenvatinib is effective and safe.
