Impact of Prior Ramucirumab Use on Treatment Outcomes of Checkpoint Inhibitors in Advanced Gastric Cancer Patients.
Article in Targeted oncology, 2020. 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
backgroundA taxane plus ramucirumab as second-line therapy followed by a checkpoint inhibitor (CPI) in third line has become a standard treatment strategy for advanced gastric cancer.
objectiveHerein, we investigated the impact of prior ramucirumab use on the efficacy of third-line immunotherapy and performed an exploratory analysis to identify potential biomarkers for the success of immunotherapy. PATIENTS AND
methodsWe retrospectively analyzed patients receiving CPI as a third-line treatment for advanced gastric cancer between January 2015 and March 2019. Clinicopathologic data, including patient characteristics, histopathologic reports, and treatment types and outcomes, were reviewed.
resultsOf the 74 patients included in this study, 45 (61%) received nivolumab and 29 (39%) received pembrolizumab as a third-line CPI. For second-line therapy, 41 patients (55%) were treated with ramucirumab plus a taxane, and 33 (45%) received a chemotherapy regimen without ramucirumab. The disease control rates of CPIs were not statistically different according to prior use of ramucirumab. The overall survival (OS) with CPI was higher in patients receiving second-line therapy without ramucirumab compared with those receiving ramucirumab and taxane (5.6 vs 4.8 months, HR 0.56, 95% confidence interval [CI] 0.33-0.96; p = 0.03); however, this was not significant in a multivariate analysis. Patients achieving a response to second-line ramucirumab and a taxane showed greater benefit from subsequent CPI treatment compared with those not achieving a response (median OS 9.9 vs 2.3 months, HR 0.20, 95% CI 0.07-0.54; p < 0.001) as found in an exploratory analysis. Multivariate analysis also showed that prior response to ramucirumab and a taxane was an independent prognostic factor of OS with third-line CPI.
conclusionsResponse to ramucirumab and a taxane as a second-line treatment is an important prognostic marker for OS with subsequent third-line CPI. This data might provide useful information when applying CPIs as third-line therapies in advanced gastric cancer patients.
