A case of obstructive shock and transient ischemic attack from intracardiac metastasis of non-small cell lung cancer (NSCLC).

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: Cancer-associated stroke (CAS) is a serious complication in cancer patients, particularly those with lung cancer. This case highlights a 76-year-old male with metastatic squamous cell carcinoma of the lung who developed obstructive shock and a transient ischemic attack (TIA) due to intracardiac metastasis. Case presentation: The patient, with a history of coronary artery disease, chronic atrial fibrillation, and obstructive sleep apnea, was diagnosed with stage IIIB squamous cell carcinoma of the lung. Imaging revealed a tumor thrombus in the left atrium, extending from the right lower lobe of the lung via the pulmonary vein. The patient presented with hemodynamic instability and a fall. A TIA with right facial droop and left pronator drift developed, which resolved within six hours. Given his poor performance status (ECOG 3), he was started on palliative radiation therapy and discharged to hospice care. Clinical discussion: Intracardiac metastasis is a rare complication of lung cancer, leading to severe hemodynamic issues and neurological events like stroke. In this case, the tumor thrombus caused obstructive shock and increased the risk of ischemic stroke. Cancer-associated stroke is more common in patients with thoracic malignancies, underscoring the need for a multidisciplinary approach to manage these complex cases. Conclusion: This case highlights the importance of early recognition and a multidisciplinary approach in managing cancer-associated strokes, particularly in patients with advanced lung cancer. Palliative care is essential for symptom management and improving quality of life. Further research is needed to explore targeted treatments for cancer-associated thrombosis.
