Lynch syndrome screening in patients with young-onset extra-colorectal Lynch syndrome-associated cancers.
Article in International journal of clinical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLynch syndrome (LS) is a hereditary cancer syndrome caused by pathogenic germline variants in mismatch repair (MMR) genes, which predisposes to various types of cancers showing deficient MMR (dMMR). Identification of LS probands is crucial to reduce cancer-related deaths in affected families. Although universal screening is recommended for colorectal and endometrial cancers, and age-restricted screening is proposed as an alternative, LS screening covering a broader spectrum of cancer types is needed. In the current study, we elucidated the rate of dMMR tumors and evaluated the outcome of LS screening in young-onset extra-colorectal LS-associated cancers.
methodsImmunohistochemistry for MMR proteins were retrospectively performed in a total of 309 tissue samples of endometrial, non-mucinous ovarian, gastric, urothelial, pancreatic, biliary tract, and adrenal cancers in patients < 50 years of age. Clinicopathological information and the results of genetic testing were obtained from medical charts.
resultsThere were 24 dMMR tumors (7.8%) including 18 endometrial, three ovarian, two urothelial, and one gastric cancer. Co-occurrence of colorectal cancer and family history of LS-associated cancers was significantly enriched in patients with dMMR tumors. Among the 16 patients with dMMR tumors who were informed of the immunohistochemistry results, five with endometrial and one with urothelial cancer were diagnosed as LS with positive pathogenic variants in MMR genes.
conclusionsWe report the outcome of immunohistochemistry for MMR proteins performed in multiple types of young-onset extra-colorectal LS-associated cancers. Our study demonstrates the feasibility of a comprehensive LS screening program incorporating young-onset patients with various types of extra-colorectal LS-associated cancers.
