An Active Trend of Immunotherapy Combination Regimen as Second-Line Therapy Towards Advanced Biliary Tract Cancer.
Article in Clinical Medicine Insights. Oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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: As a second-line therapy, oxaliplatin/fluorouracil/leucovorin (FOLFOX) remains the standard of care for patients with biliary tract cancer (BTC); however, its efficacy is suboptimal. The aim of this study was to evaluate whether, compared with chemotherapy alone, the immune checkpoint inhibitor (ICI) combination regimen improved the overall survival (OS) in patients with advanced BTC. Methods: Patients diagnosed with advanced BTC who received chemotherapy or ICI combination therapy as second-line (L2) treatment between January 1, 2018, and April 1, 2022, were retrospectively identified. Results: A total of 98 patients with BTCs were reviewed and recruited: the chemotherapy group (cohort A, n = 40), the chemotherapy plus ICIs group (cohort B, n = 27), and the tyrosine kinase inhibitor (TKIs) plus ICIs group (cohort C, n = 31). The median progression-free survival (PFS) and median OS were 2.6 months (95% confidence interval [CI]: 1.7-4.2) and 7.8 months (95% CI: 5.9-12.0) for cohort A, 4.3 months (95% CI: 2.9-8.4) and 10.9 months (95% CI: 7.67-NA) for cohort B, 5.1 months (95% CI: 4.0-8.3) and 10.1 months (95% CI: 8.23-NA) for cohort C, respectively. The confirmed overall response rates were 7.5% (3/40, cohort A), 22.2% (6/27, cohort B), and 19.4% (6/31, cohort C), whereas the disease control rates were 47.5% (19/40, cohort A), 77.8% (21/27, cohort B), and 77.4% (24/31, cohort C). Grade 3 or higher treatment-related adverse reaction were reported in 20.0% (cohort A), 37.0% (cohort B), and 41.9% (cohort C) of the patients. Conclusions: The ICI combination strategy beyond first-line (L1) systemic chemotherapy plays a positive role in advanced BTCs. Both TKIs plus ICIs and chemotherapy plus ICIs could be considered candidates for trials and applied as competitive L2 treatment regimens for advanced BTCs in clinical practice.
