Response to Pyrotinib in a Patient with Metastatic Bladder Urothelial Carcinoma Harboring HER2 V842I Mutation: A Case Report.
Article in Cancer management and research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: The highest incidence of human epidermal growth factor receptor 2 (HER2) mutations has been observed in bladder cancer (BC). However, the function of HER2 mutation in tumor progression and metastasis remains unclear. Currently, no responses to the pan-HER kinase inhibitor were observed in HER2-mutant BC. Case Presentation: We described a patient with metastatic bladder urothelial carcinoma (BUC) carrying a HER2 V842I mutation both in circulating tumor DNA (ctDNA) and biopsy sample. The patient was then treated with a HER2 tyrosine kinase inhibitor, pyrotinib, and responded well. However, the targeting treatment was terminated due to G3 diarrhea. Reduced dose of pyrotinib was later added to late-line treatment, the patient's tumor again responded with a significant decrease in CA199. Conclusion: This is the first reported case of HER2 V842I mutation successfully treated with pyrotinib in BUC, suggesting pyrotinib therapy might serve as a therapeutic option for BUC patients harboring HER2 activating mutation.
