Abstract

fetched live from OpenAlex

Introdução: Lesões serrilhadas são consideradas precursoras dos adenocarcinomas colorretais. Estudá-las em suas fases iniciais é importante ao pensar na prevenção do câncer, quando, então, são lesões hiperplásicas, ou sésseis serrilhadas Objetivo: Realizar revisão integrativa da literatura para comparar as características endoscópicas e histopatológicas nas fases iniciais da doença, com a intenção de auxiliar no entendimento do câncer colorretal. Métodos: Revisão integrativa da literatura baseada em material de análise existente nas plataformas digitais SciELO – Scientific Electronic Library Online, Google Scholar, Pubmed e Scopus. O início foi a busca com os seguintes descritores: “lesões sésseis serrilhadas, carcinoma colorretal, lesões superficiais”, e seus equivalentes em inglês “serrated sessile lesions, colorectal carcinoma, superficial lesions” com busca AND ou OR, considerando o título e/ou resumo, e incluindo-se posteriormente somente aqueles com maior correlação para leitura dos textos completos. Resultados: Incluíram-se 39 artigos. Conclusão: A maioria das lesões serrilhadas superficialmente elevadas com mais de 5 mm e ressecadas por colonoscopias, são hiperplásicas. Elas ocorrem por todo o cólon e reto, enquanto as sésseis serrilhadas localizam-se preferencialmente no cólon proximal. As hiperplásicas geralmente não apresentam displasias e as sésseis serrilhadas podem tê-las de forma intensa.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
