Brain Freeze: Pembrolizumab-Induced Autoimmune Encephalitis in Triple-Negative Breast Cancer.

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
This case report presents the first known instance of pembrolizumab-induced autoimmune encephalitis in a 41-year-old female patient with stage IIIc triple-negative breast cancer. The patient developed expressive aphasia three days after starting pembrolizumab in combination with chemotherapy, prompting comprehensive evaluations that ruled out infectious or metastatic causes. A diagnosis of pembrolizumab-associated autoimmune encephalitis was established following a lumbar puncture and MRI. After discontinuing the immune checkpoint inhibitors (ICI) and initiating high-dose corticosteroids (methylprednisolone), the patient's symptoms significantly improved within days. This case highlights the importance of recognizing and managing neurological immune-related adverse events (irAEs) associated with ICIs, as their incidence can be variable but potentially severe. Clinicians must maintain a high index of suspicion for neurological irAEs, especially with new neurological symptoms, as early diagnosis and intervention are crucial for optimizing patient outcomes while balancing effective cancer treatment. Ongoing research is essential to elucidate the mechanisms and management strategies for ICI-related autoimmune encephalitis.
