Clival metastasis of hepatocellular carcinoma: a case report of a rare skull-base malignancy.
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
Introduction: Hepatocellular carcinoma is the most common neoplasm of the liver. It metastasizes mainly to local lymph nodes, lungs, adrenal glands, vertebrae, pelvis, ribs and long bones. Metastasis to the clivus is extremely rare. Only a few cases have been described in the literature. Therefore, there is currently no clear consensus on the optimal treatment: biopsy only or maximum safe removal. Case report: We present a 68-year-old lady who presented with dysfunction of the 6th and 12th cranial nerves. Imaging showed tumor formation in the clivus, most likely a metastasis. Further diagnostics revealed no clear primary tumor. The patient therefore underwent surgery for local decompression and simultaneous biopsy for pathohistologic examinations. These showed that the most likely metastasis was a hepatocellular carcinoma. Subsequent diagnostics revealed highly elevated alpha-feto protein levels and liver MR revealed a suspected multifocal hepatocellular carcinoma only after correlation with the pathohistologic findings. One month after surgery, the condition suddenly worsened due to severe local recurrence and hemorrhage. This was followed by palliative oncological treatment with whole head irradiation. Conclusion: In the case of a suspected clivus metastasis of unknown origin, it is reasonable to take tumor markers. This increases the likelihood of an appropriate diagnosis and avoids unnecessary and risky surgery. If all tests are inconclusive, a biopsy of the lesion is the diagnostic gold standard. The treatment of metastatic disease in the clivus (in our case a hepatocellular carcinoma) remains palliative.
