Clinical significance of detecting elevated serum DcR3/TR6/M68 in malignant tumor patients
Bibliographic record
Abstract
TR6/DcR3/M68 is a soluble receptor that belongs to the TNF receptor family. It is expressed in malignant cells of several tumor types and has been postulated to help tumor cells to gain survival advantage by inhibiting apoptosis and by interfering with immune surveillance. In our study, we assessed for the first time serum TR6 in tumor patients to explore its diagnostic and prognostic value. We examined serum TR6 levels with ELISA in 146 tumor patients, 19 patients with acute infection, 5 patients with liver cirrhosis and 29 healthy individuals. TR6 expression in tumor mass was studied with immunohistochemistry. TR6 gene copy number in tumor tissues was evaluated by real time PCR. Ninety-seven point nine percent (47 of 48 cases) of healthy individuals and patients with acute infection were serum TR6-negative. In contrast, 56.2% (82 of 146 cases) of the tumor patients were serum TR6-positive. Almost all serum TR6-positive individuals (98.8%, 82 out of 83 cases) had malignancy, excluding the cases of liver cirrhosis. In gastric carcinomas, serum TR6 levels were closely correlated with tumor differentiation status and TNM classification. Tumor mass was the source of serum TR6 because its levels decreased drastically after curative tumor resection. TR6 gene amplification occurred in about half of liver carcinomas, but not in gastric or pancreatic carcinomas, indicating plural mechanisms of TR6 upregulation. Our study demonstrated that serum TR6 should be considered as a novel parameter for the diagnosis, treatment and prognosis of malignancies.

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.
