Evaluation of <sup>177</sup>Lu-EDTMP in Dogs with Spontaneous Tumor Involving Bone: Pharmacokinetics, Dosimetry and Therapeutic Efficacy
Bibliographic record
Abstract
177Lu-EDTMP is currently being investigated as a potential agent for providing palliative care to the patients suffering from bone pain due to metastatic skeletal carcinoma. The present article describes the evaluation of 177Lu-EDTMP complex in four different canine patients with different types of primary and metastatic skeletal lesions with respect to its pharmacokinetic properties, dosimetry and therapeutic efficacy. The dogs were treated with a dose of ~44.4 MBq (1.2 mCi) per kg body weight of 177Lu-EDTMP, synthesized in-house with high radiochemical purity (98.8 ± 0.4 %) and excellent in vitro stability. The radiopharmaceutical showed favourable pharmacokinetic properties, such as, preferential accumulation at skeletal lesion sites and fast clearance from blood and other non-target organs through urinary route. The administered dose of the radiopharmacutical showed excellent therapeutic efficacy in case of a dog suffering from skeletal metastasis originating from primary tumor elsewhere. On the other hand, two of the remaining three patients with primary bone cancer showed stable disease intially with palliative effect. The fourth patient having metal implant induced osteosarcoma with severe limb oedema did not show any response to the treatment.

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.
