Immune-related osteoblastic bone alterations mimicking bone metastasis in a small-cell lung cancer patient treated with durvalumab: a case report.

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
Background: Chemotherapy combined with immunotherapy is currently the standard first-line treatment for advanced small-cell lung cancer (SCLC). Immunotherapy can induce specific adverse events, called immune-related adverse events (irAEs). IrAEs of bones have rarely been reported. However, identifying bone irAEs could be important in avoiding misdiagnosis and ensuring appropriate patient management. This is the first report describing the diagnosis of irAEs of osteoblastic bone changes mimicking bone metastasis in a SCLC patient treated with durvalumab. Case Description: In this report, we describe a unique and challenging case in which a 54-year-old female patient with SCLC treated with durvalumab, an immunotherapy drug, exhibited osteoblastic bone changes that appeared similar to bone metastasis on imaging but were actually a side effect of immunotherapy. Before treatment, imaging revealed no bone metastasis. In the third month after treatment with durvalumab, computed tomography (CT) revealed multiple bone alterations, predominantly osteoblastic lesions with minor osteolytic changes. Various imaging tests suggested bone metastasis, but she had no symptoms related to bone disease. Notably, the lesions in the chest had achieved a partial response. Based on a comprehensive analysis of the CT-guided pathological biopsy results, the patient's symptoms, and the biological characteristics of SCLC, we determined that these bone changes were irAEs occurring in the skeletal system. The patient was followed up for 10 months, during which time the bone lesions remained stable. Conclusions: IrAEs of bones are rare, and their manifestations vary. Sometimes, the imaging manifestations of bone irAEs are difficult to distinguish from bone metastasis. If patients show variable treatment responses between different lesions, careful evaluation (including a pathological biopsy) is necessary.
