Abstract

fetched live from OpenAlex

Anal dysplasia and intraepithelial neoplasia are part of a continuum of anal cancer that is typically treated with curative intent. Surveillance after treatment in our practice includes high-resolution anoscopy. This is similar to colposcopy in cervical cancer screening and treatment programs. It allows for the visualization of the anal canal, with biopsy of suspicious looking lesions [1]. In Canada, high-resolution anoscopy is performed in a few outpatient settings, and constitutes part of a screening program for individuals who are at high risk for anal dysplasia due to human papillomavirus (e.g., men who have sex with men and HIV-positive individuals). These high-risk individuals are usually screened with an anal Pap smear, and referred for high-resolution anoscopy if the cytology result is abnormal. Following high-resolution anoscopy, biopsy may be indicated. If the biopsy shows high-grade dysplasia (anal intraepithelial neoplasia II/III, carcinoma in situ), lesions are treated with either 80 % trichloroacetic acid or infrared coagulation. Recent data on infrared coagulation show that it is a safe and effective office-based procedure, and that repeated treatments lead to resolution of the high-grade dysplasia [2].

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
