Case Report: Metastatic lung cancer in Meckel's Cave: a radiotherapy successful case and literature review.
Article in Frontiers in oncology, 2025. 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
Background: Meckel's cave (MC) is a highly uncommon site for metastatic disease, particularly from primary lung cancer. Case presentation: We report a clinical case of a 70-year-old man presenting with left trigeminal pain, left ptosis, and restricted abduction of the left eyeball. The patient had a 2-year history of stage IV lung squamous cell carcinoma. Contrast-enhanced brain MRI and FDG-PET/CT showed an ill-defined mass with a heterogeneously enhancing lesion involving the left MC and middle cranial fossa. Stereotactic radiosurgery (SRS, 30 Gy/5 fx) achieved significant improvement in symptoms and regression of radiologic tumors within 1 month. Our review of relevant literature identified only two reported cases of lung adenocarcinoma metastasizing to MC. In addition, we examined the limited literature on other malignant tumors metastatic to MC managed with radiotherapy. Conclusion: This is the first reported case of MC metastasis from lung squamous cell carcinoma successfully treated with SRS. Effective management of MC metastasis requires histology-specific radiotherapy strategies, with squamous cell carcinoma benefiting from hypofractionated SRS.
