Adverse Events in Patients With Esophageal Cancer Treated With Nivolumab in Combination With Radiotherapy.
Article in In vivo (Athens, Greece). 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
BACKGROUND/
aimWhen nivolumab is administered as second-line therapy for esophageal cancer, radiotherapy may also be provided in cases either concurrently or sequentially. The aim of this study was to retrospectively examine whether the incidence of adverse events increases in such cases. PATIENTS AND
methodsTwenty-two esophageal cancer patients [17 males and 5 females; mean age 71 years (range=58-87 years)] treated with nivolumab were included. Patients were divided into two treatment groups: nivolumab alone (N group) (12 patients) and nivolumab combined with radiotherapy (R group) (10 patients). All patients had squamous cell carcinoma. The primary outcomes measured were the severity and frequency of adverse events.
resultsAdverse events were seen in 6 of the 12 patients in the N group and 8 of the 10 in the R group. There were significantly more adverse events in the R group (p=0.035), but no difference in Grade 3 or higher adverse events (p=0.781), indicating that the adverse events were controllable. There was no significant difference in treatment effect between the N and R groups.
conclusionIn this report, 50% of adverse events in the N group were grade 3-4, 25% of which were grade 4, as seen in previous reports. In the present study, the side effects were not enhanced by treatment with immune checkpoint inhibitors plus radiotherapy. Immune checkpoint inhibitors plus radiation therapy would be a relatively safe treatment and may become an option for esophageal cancer treatment in the future.
