Does salmon calcitonin cause cancer? A review and meta-analysis
Bibliographic record
Abstract
Recently an association between the use of calcitonin and cancer has been postulated. We reviewed the biological rationale and performed an additional analysis of historical data with respect to the possibility. An association cannot be excluded, but the relationship is weak and causality is unlikely. The purpose of the present study is to review the strength of association and likelihood of a causal relationship between use of calcitonin and cancer. We reviewed the evidence for this association, including the molecular signaling mechanisms of calcitonin, preclinical data, an "experiment of nature," and the results of a previous meta-analysis which showed a weak association. We performed an additional meta-analysis to incorporate the data from a novel investigational oral formulation of salmon calcitonin. Review of the literature did not identify a cellular signaling mechanism of action which might account for a causal relationship or toxicologic or postmarketing data to support the thesis. Additional clinical results incorporated into previous meta-analyses weakened but did not completely negate the possibility of association. A causal association between calcitonin use and malignancy is unlikely, as there is little biological plausibility. The preponderance of nonclinical and clinical evidence also does not favor a causal relationship.

How this classification was reachedexpand
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.
