Successful Management of Immune-Mediated Myelitis in a Renal Cancer Patient: A Case Report.
Article in Case reports in oncology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Immune checkpoint inhibitors (ICIs) have revolutionized metastatic renal cell carcinoma treatment, significantly improving survival outcomes. However, ICIs are linked to immune-related adverse events (irAEs), which can impact multiple organs. Neurological irAEs, such as myelitis, are rare but potentially severe. Case Presentation: We describe a 54-year-old male with high-grade clear cell renal carcinoma treated with nivolumab and ipilimumab. After four cycles, he developed hypophysitis, adrenal insufficiency, and hypothyroidism, managed with hydrocortisone and levothyroxine, while continuing nivolumab monotherapy. In August 2022, he experienced right eyelid ptosis and right hand weakness. Cranial magnetic resonance imaging (MRI) showed improvement in the sellar lesion, and chronic sensorimotor polyneuropathy was diagnosed, ruling out myasthenia gravis. Nivolumab treatment continued. By December 2022, after seven cycles, the patient developed back pain and dysesthesias, with MRI confirming transverse myelitis from C7 to T3. Nivolumab was discontinued, and high-dose corticosteroids (1 g methylprednisolone daily for 5 days) led to clinical improvement. A 12-week taper followed, with no symptom recurrence. Disease progression in April 2023 led to a switch to pazopanib, maintaining a partial response for 6 months. Conclusion: This case emphasizes the serious nature of neurological irAEs from ICIs and the critical need for early detection and management. It also highlights the increased risk of subsequent irAEs after an initial event, underscoring the importance of vigilant monitoring.
