Pembrolizumab Monotherapy
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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/
aimPembrolizumab monotherapy and pembrolizumab with chemotherapy (combination therapy) are standard treatments for recurrent and metastatic head and neck squamous cell carcinoma (R/M-HNSCC). This study aimed to explore which of the two, pembrolizumab monotherapy or combination therapy is superior for long-term use. PATIENTS AND
methodsParticipants of the study were 139 patients with histologically confirmed squamous cell carcinoma who had been treated with pembrolizumab monotherapy or combination therapy at the Kyushu University and related facilities. We analysed differences regarding long-term survival rate and adverse events (AEs) between the pembrolizumab monotherapy and combination therapy groups.
resultsThe overall 2-year progression-free survival and 2-year overall survival were 28.6% and 41.8%, respectively; these results were not significantly different between the two groups. Patients in the monotherapy group with AEs had a significantly better prognosis than those without AEs (in both the monotherapy and combination therapy groups). In the combination therapy group, there was no difference in prognosis between those with AEs and those without AEs (p=0.636).
conclusionConsidering the treatment of R/M-HNSCC from a long-term perspective, we identified that it is better to use pembrolizumab as monotherapy than to use it in combination with chemotherapy. Combination therapy did not improve prognosis; moreover, it can also cause additional adverse effects.
