Folliculotropism Does Not Affect Overall Survival in Mycosis Fungoides: Results from a Single-Center Cohort and Meta-Analysis
Bibliographic record
Abstract
BACKGROUND: Folliculotropic mycosis fungoides (FMF) is a distinct subtype of mycosis fungoides (MF) with unique clinicopathological features. The medical literature suggests that FMF has a more aggressive course and worse survival than classic MF. Previous studies do not use standardized treatment, and no studies have reported an association between treatment response and overall survival (OS). OBJECTIVE: To compare OS for MF, FMF, and Sézary syndrome (SS) patients. METHODS: Data were collected retrospectively from 218 patients (171 MF, 15 SS, 32 FMF) treated in a single academic center between 1970 and 2016. RESULTS: Negative predictors of OS were age (OR = 1.07), male sex (OR = 1.63), and stage IIB, III, and IV (OR = 4.10, 5.42, and 7.54, respectively, vs. stage IA). Lack of initial PUVA response was strongly associated with negative OS (OR = 3.08). Kaplan-Meier analysis of age-, sex-, and stage-matched MF and FMF patients found similar OS between the 2 groups. The 5-year OS was 91% for FMF and 74% for MF. Meta-analysis of current data and 2 published studies where survival of FMF patients was compared to MF did not reveal statistically significant differences between these 2 diseases. CONCLUSIONS: When patients were matched for age, sex, and disease stage, folliculotropism did not affect OS in MF.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
