Comparison of the efficacy of pre-surgery and post-surgery radiotherapy in the treatment of hepatocellular carcinoma: a population-based study.
Article in American journal of translational research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundRadiotherapy has been widely used in the treatment of hepatocellular carcinoma (HCC). However, whether the patients should receive radiotherapy before or after surgical treatment has not been studied. The objective of the study was to compare the efficacy of the treatment in HCC patients who received pre-surgery and post-surgery radiotherapy.
methodsData from the Surveillance, Epidemiology, and End Results (SEER) database were analyzed. Patients with surgery combined with radiotherapy were included into the study. The outcome measures were overall survival (OS) and cancer-specific survival (CSS). Propensity score matching (PSM) was used to reduce selection bias.
resultsBefore PSM, the median OS (mOS: 82 months) and median CSS (mCSS: NA) in the pre-surgery group were longer than in the post-surgery group (mOS: 21 months; mCSS: 20 months; P<0.001 for both). After PSM, the mOS and mCSS in the pre-surgery group were longer than in the post-surgery group (mOS: 45 vs. 26 months, P=0.011; mCSS: 60 vs. 26 months, P=0.003). The subgroup analysis documented that patients with single tumor, liver resection, and American Joint Committee on Cancer (AJCC) stage I and II had longer mOS and mCSS if they received pre-surgery rather than post-surgery radiotherapy (all P<0.05). Multivariate regression analysis showed patients with post-surgery radiotherapy had a higher risk of mortality than patients with post-surgery radiotherapy.
conclusionHCC patients with single tumor, AJCC stage I and II, or with liver resection who received pre-surgery radiotherapy have better survival benefits than patients receiving post-surgery radiotherapy, particularly if internal radiotherapy was used.
