A prospective Phase II study for the efficacy of radiotherapy in combination with zoledronic acid in treating painful bone metastases from gastrointestinal cancers.
Trial report in Journal of radiation research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
We investigated the efficacy of combined radiotherapy (RT) and zoledronic acid in treating painful bone metastases from gastrointestinal cancers. Sixty patients were prospectively enrolled between November 2014 and July 2016. The most common primary cancer type was hepatocellular carcinoma (HCC, n = 25), followed by colorectal cancer (n = 6). Patients received external beam RT of 30-54 Gy in 10-17 fractions or 20 Gy in 5 fractions for symptomatic bone metastases. On the first day of RT, patients received 4 mg intravenous zoledronic acid, which was repeated monthly for a total of six cycles. The mean pain score before treatment was 6.7, and it decreased to 2.8 at 1 month and 2.1 at 3 months (P < 0.001).The overall pain response rates at 1 and 3 months were 95% and 96%, respectively. Among the 24 patients who underwent magnetic resonance imaging, 71% were responders, with a complete response in 1 patient and partial in 16 patients. Combined treatment significantly decreased levels of macrophage inflammatory protein-1α and matrix metalloproteinase (MMP)-2 and -3 compared with baseline (all P < 0.05). In HCC patients, IL-6 and MMP-9 levels were significantly lower 1 month after treatment (P < 0.05). The mean quality of life (QOL) score improved from 66 to 56 at 1 month (P < 0.001) and 55 at 3 months (P = 0.016). The median survival was 7 months. In conclusion, RT with zoledronic acid decreased bone pain and improved QOL in patients with painful bone metastases from gastrointestinal cancers. Radiographic findings and serum biomarker measurements were closely correlated with therapeutic responses.
