Incidence of Hypercalcemia and Vertebral Fractures Following Denosumab Withdrawal in Lung Cancer Patients: A Longitudinal Cohort Study.
Article in Journal of bone metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundBone-target agents (BTAs), including denosumab (DMAb), are one of the bone metastasis treatments that should continue indefinitely. However, BTAs may be interrupted in some cases. In osteoporosis, DMAb withdrawal causes a rebound effect characterized by an increased bone turnover with spine fractures and hypercalcemia; evidence of the DMAb withdrawal effect in oncology is lacking.
methodsThis study aimed to identify the DMAb withdrawal effect amongst lung cancer patients treated with DMAb for bone metastases between January 2020 and December 2021. Patients who discontinued DMAb were included. Encounter notes, radiological and laboratory findings were comprehensively reviewed.
resultsThirty patients were included with a median follow-up of 21 months (interquartile range [IQR], 10-30) after DMAb discontinuation. Bisphosphonates were administered before starting DMAb in 7 patients (23.3%) and after DMAb withdrawal in 4 cases (13.3%). Three cases of DMAb withdrawal-related hypercalcemia and 3 cases of spine fractures following DMAb cessation were identified in 5 patients (16.7%), all of them were females and the median age was 65 years old (IQR, 65-70). No statistical difference in DMAb duration or number of injections was found in patients developing DMAb withdrawal-related spine fractures or hypercalcemia compared with others (binary logistic regression, p=0.688 and p=0.938, respectively).
conclusionsPatients with bony-metastatic lung cancer, especially post-menopausal women, are at risk of fractures and calcium abnormalities after DMAb discontinuation, suggesting that DMAb withdrawal effect may also be present in the oncological setting. A close follow-up and careful monitoring during and after discontinuation of DMAb is necessary.
