Phase II trial of stereotactic body radiation therapy on adrenal gland metastases: evaluation of efficacy and impact on hormonal production.
Trial report in Journal of cancer research and clinical oncology, 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
purposeThe purpose of this study was to assess prospectively the efficacy and safety of stereotactic body radiation therapy (SBRT) for adrenal gland metastasis, with a focus on the assessment of the irradiated subjects' endocrinological function. MATERIALS AND
methodsA total of 36 patients were enrolled from 2017 to 2020 in this prospective phase II trial. Patients were treated with Linac-based SBRT, with a dose of 45 Gy in 3 consecutive fractions. Primary end-point was local control (LC) of the treated lesions and secondary end-points included evaluation of acute and late toxicity, progression free survival (PFS), overall survival (OS) and the impact on the hormonal production of adrenal glands.
resultsWith a median follow-up of 9.5 months, LC rates at 1 and 2 years were 94.7% and 88.4%, respectively. Rates of PFS at 1 and 2 years were 50.5% and 29.8%, with a median PFS of 14.7 months. Rates of OS at 1 and 2 years were 62.9% and 44.1%. At univariate analysis, oligorecurrence was associated with better OS compared to oligoprogressive or synchronous metastatic disease. No grade 3 or greater toxicities were registered and only a minority of patients (22.2%) reported mild treatment-related side effects. Hormonal and electrolytes production was assessed before and after treatment, showing only a slight and transient variation within the reference ranges.
conclusionSBRT on adrenal metastases has been confirmed to be a feasible and effective treatment. With an excellent disease control and the preservation of the endocrine function, SBRT with ablative dose can be considered a viable alternative to more invasive approaches.
