Case Report: Successful conversion of gallbladder cancer with intrahepatic metastases using camrelizumab combined with gemcitabine and cisplatin.
Article in Frontiers in immunology, 2026. 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: Gallbladder cancer is an extremely aggressive malignant tumor of the digestive system. It presents with no obvious symptoms in its early stages, meaning most patients are already in advanced stages at diagnosis. The response to neoadjuvant therapy for gallbladder cancer is poor, and the majority of patients with advanced gallbladder cancer cannot achieve tumor downstaging through drug treatment to become eligible for surgery. This case focuses on discussing the selection of immunotherapy drugs and the determination of their treatment cycles. Case summary: This case report describes a patient with gallbladder cancer and intrahepatic metastases. Following contrast-enhanced computed tomography (CECT) evaluation, R0 resection of the lesions was deemed unfeasible. The patient underwent conversion therapy with camrelizumab combined with gemcitabine and cisplatin. The patient responded well to this regimen, with rapid tumor shrinkage after three cycles of treatment. Grade IV neutropenia developed during therapy but resolved without serious consequences following prompt intervention. After reassessment, the patient underwent open cholecystectomy combined with segmental resection of the liver segments IVb/V, lymph node dissection, and high hepaticojejunal anastomosis. Postoperative recovery was favorable, with PFS reaching 18 months. Conclusion: The regimen of camrelizumab combined with gemcitabine and cisplatin demonstrated potential conversion therapy value in this patient with advanced gallbladder cancer. However, its definitive efficacy and the specific role of camrelizumab still require validation through large-scale clinical trials.
