Efficacy of neoadjuvant immunotherapy in advanced colorectal cancer: a meta-analysis of cross-sectional studies.
Synthesis in Journal of cancer research and clinical oncology, 2023. 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
backgroundAlthough neoadjuvant immunotherapy is being widely studied, there is no consensus on its efficacy in microsatellite-stable (MSS) or mismatch repair proficient (pMMR) colorectal cancer (CRC). This meta-analysis aimed to evaluate studies on neoadjuvant immunotherapy for advanced CRC to assess its efficacy and provide new clinical guidelines.
methodsWe searched literature databases to identify studies that assessed the efficacy of neoadjuvant immunotherapy in advanced CRC. The outcomes evaluated were pathological complete response (pCR), major pathological response (MPR), R0 resection, and anal preservation rates. Heterogeneity among the included studies was assessed by sensitivity analysis, and publication bias was evaluated using Begg and Egger tests.
resultsEleven articles were included in the analysis. The pCR, MPR, R0 resection, and anal preservation rates reported in these studies were 39 and 49, 97, and 76%, respectively. The MSI-H and MSS groups had pooled pCR rates of 70 and 24%, respectively. The pCR rates for the induction, consolidation, and concurrent immuno-chemoradiotherapy (CRT) subgroups were 43, 33, and 27%, respectively, and those for the single and double immunotherapy subgroups were 34 and 40%, respectively.
conclusionNeoadjuvant immunotherapy combined with CRT is effective in treating MSI-H/dMMR advanced CRC. It could also be a new first-line therapeutic option for MSS/pMMR advanced CRC.
