Immunohistochemical evaluation of microsatellite instability in resected colorectal liver metastases: a preliminary experience.
Article in Medical oncology (Northwood, London, England), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 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
In this retrospective study, we evaluated the predictive role of different immunohistochemical expression (IHC) of the mismatch repair proteins (MMR) in patients with colorectal liver metastasis (CRLM) submitted to liver resection. A total of 108 patients were retrieved, and 15 patients were excluded from the study because of the impossibility to obtain adequate formalin-fixed tissue blocks. The final analysis included 93 patients. Twenty-eight cases (30%) presented a no loss of expression or microsatellite stability (MSS) status, 59 cases (63%) showed a hybrid loss of expression, while 6 cases (7%) presented a complete loss of expression or microsatellite instability status (MSI). Patients with complete or hybrid loss of expression of MMR developed a high intra-hepatic recurrence rate compared to other ones (54% vs 21% OR of 4.278, 95% CI 1.53-11.93) (p = 0.004). The same difference in terms of liver recurrence has been found among patients with R0 resection (50% vs 17% OR of 0.2, 95% CI 0.06-0.65) (p = 0.005). However, there was no difference in terms of disease-free survival and overall survival. Complete or hybrid loss of expression of MMR could be considered a risk factor for intra-hepatic recurrences after liver resections for CRLM.
