Nerve cut may supercharge tongue cancer treatment

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age 18-75 years, male or female. 2. Histologically or cytologically confirmed primary tongue squamous cell carcinoma (cT3 or cT4). 3. Patients scheduled to receive 2 cycles of preoperative neoadjuvant chemoimmunotherapy with tirelizumab, cisplatin, and albumin-bound paclitaxel. 4. Patients planned to undergo surgical resection of tongue cancer following neoadjuvant therapy. 5. Voluntary participation with signed informed consent, good compliance, and willingness to follow study procedures. Exclusion Criteria: 1. Known distant metastases of the tumor. 2. History of tongue squamous cell carcinoma or other malignant tumors of the tongue within the past 5 years. 3. Active infection requiring systemic therapy; non-infectious pneumonia or interstitial lung disease requiring steroid therapy, or current pneumonia/interstitial lung disease; known hepatitis B infection (HBsAg positive) or active hepatitis C infection (detectable HCV RNA); known HIV infection. 4. Previous allogeneic tissue or organ transplantation. 5. Unresolved ≥Grade 2 (CTCAE v5.0) toxicities from prior anticancer treatments, except alopecia. 6. Significant cardiovascular abnormalities (e.g., myocardial infarction, superior vena cava syndrome, NYHA class ≥II heart disease within 3 months prior to enrollment). 7. Active serious clinical infections (\>Grade 2 NCI-CTCAE v5.0). 8. Uncontrolled hypertension (treated systolic BP \>150 mmHg and/or diastolic BP \>90 mmHg) or clinically significant cardiovascular disease, including recent cerebrovascular accident or myocardial infarction (≤6 months), unstable angina, NYHA class ≥II congestive heart failure, or severe arrhythmia not controlled by medication that could affect study treatment. 9. Laboratory abnormalities: Hematology: WBC \<3,000/mm³, Hb \<8 g/dL, platelets \<80,000/mm³ Liver function: ALT/AST \>3× upper limit of normal, bilirubin \>1.5× ULN Renal function: serum creatinine \>1.5× ULN, renal failure requiring dialysis Diabetes: poorly controlled (FBG \>10 mmol/L) Proteinuria: urine protein ≥++ and 24-hour urine protein \>1.0 g 10. Pregnant women; breastfeeding women must discontinue breastfeeding to participate. 11. History of substance abuse or psychiatric disorders that would interfere with study participation. 12. Participation in another clinical trial within 30 days prior to enrollment.
