This protocol (Protocol No.: \\[To be filled\\]) has been reviewed and approved by the Ethics Committee of the Army Center of Specialized Medicine.\n\nI. Background and Objectives 1.1 Disease Burden and Current Treatments 1.1.1 Thyroid Cancer Surgery Thyroid cancer, the most common head and neck malignancy, exhibits rising global incidence. Central compartment lymph nodes are frequent sites of metastasis in papillary thyroid carcinoma (PTC). Transoral endoscopic thyroid surgery offers superior cosmesis versus open surgery. The da Vinci® robotic system enhances visualization and instrument maneuverability, overcoming technical limitations of narrow endoscopic operating channels.\n\n1.1.2 Lymphatic Tracers in Thyroid Surgery\n\nMitoxantrone Hydrochloride Injection for Lymphatic Tracing is China's only approved tracer for thyroid lymphatic mapping. Its high lymphotropic specificity enables:\n\nLymph node mapping: Forms nanocrystals that permeate lymphatics, staining nodes blue.\n\nParathyroid negative imaging: Spares parathyroid glands, aiding their identification and reducing postoperative hypocalcemia.\n\n1.2 Study Objectives\n\nPrimary: Compare lymph node dissection efficacy and parathyroid protection between:\n\nIntervention: Transoral robotic thyroid lobectomy\u002Ftotal thyroidectomy + central neck dissection (CND) with lymphatic tracing.\n\nControl: Identical surgery without tracing.\n\nSecondary:\n\n1. Compare postoperative parathyroid function between groups.\n2. Evaluate tracer sensitivity for metastatic lymph nodes.\n\n1.3 Participating Site and Sample Size Site: Army Center of Specialized Medicine Sample: 114 treatment-naïve PTC patients scheduled for transoral robotic surgery (Jan-Dec 2024).\n\nIntervention group (n=57): Mitoxantrone Hydrochloride tracing Control group (n=57): No tracer II. Study Procedures Pre-study: Medical history review, preoperative assessments, and documentation of concomitant medications (30 days postsurgery).\n\nIntervention:\n\nThyroid exposure → Intervention group: Multisite intraglandular tracer injection (0.1 mL\u002Fsite, depth ≈0.3 cm; total dose thyroid-dependent).\n\nBoth groups: Thyroid lobectomy\u002Ftotal thyroidectomy ± unilateral\u002Fbilateral CND. Intraoperative recording: Thyroid characteristics, tracer dose\u002Finjection sites, lymphadenectomy duration.\n\nPathology:\n\nTotal lymph node yield and blue-staining rate. Intraoperative frozen section + final histopathology for metastatic nodes.\n\nFollow-up (Postoperative Day 7±3):\n\nPhysical exam, vital signs, lab tests (CBC, biochemistry, thyroid\u002Fparathyroid hormones, electrolytes).\n\n12-lead ECG. Safety monitoring: Adverse events (AEs) tracked until Postoperative Day 14. III. Potential Benefits Improved lymphatic mapping → Reduced parathyroid injury, enhanced lymph node clearance, lower AE rates.\n\nTracer provided at no cost by the sponsor. Note: Efficacy is not guaranteed. Alternative treatments exist. IV. Risks and Inconveniences Potential AEs: Per product labeling and surgical risks. Procedural burdens: Multiple hospital visits and tests. AE management: Immediate medical intervention provided. Compensation per GCP regulations if injury is trial-related.\n\nV. Costs Tracer: NMPA-approved and insurance-covered. Routine care\u002Fmedications: Patient\u002Finsurance responsibility. AE compensation: Sponsor-covered if causally related (per Chinese GCP). VI. Confidentiality\n\nMedical records accessible only to:\n\nResearch team Ethics Committee Regulatory authorities No personally identifiable data will be published. VII.
