Há diferenças endoscópicas e histopatológicas entre lesões serrilhadas superficiais nas suas fases iniciais?
Bibliographic record
Abstract
Introduction: Serrated lesions are considered precursors of colorectal adenocarcinomas. Studying them in their initial phases is important when thinking about cancer prevention, when they are hyperplastic lesions, or sessile serrated lesions. Objective: To carry out an integrative review of the literature to compare the endoscopic and histopathological characteristics in the initial phases of the disease, with the intention to help understand colorectal cancer. Methods: Integrative literature review based on existing analysis material on the digital platforms SciELO – Scientific Electronic Library Online, Google Scholar, Pubmed and Scopus. The beginning was the search with the following descriptors: “serrated sessile lesions, colorectal carcinoma, superficial lesions”, with AND or OR search, considering the title and/or abstract , and subsequently including only those with the highest correlation for reading the full texts. Results: 39 articles were included. Conclusion: The majority of superficially elevated serrated lesions measuring more than 5 mm and resected by colonoscopies are hyperplastic. They occur throughout the colon and rectum, while the serrated sessiles are preferentially located in the proximal colon. Hyperplastic ones generally do not present dysplasias and sessile serrated ones can have them intensely.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
