- \*\*Bone marrow function (without transfusion or growth factor support):\*\*
- Absolute neutrophil count (ANC) ≥1.5 × 10⁹/L (1500/μL)
- Hemoglobin ≥90 g/L (9.0 g/dL)
- Platelet count ≥100 × 10⁹/L (100,000/μL)
- \*\*Liver function:\*\*
- Total bilirubin (TBIL) ≤1.5 × ULN
- AST, ALT, and alkaline phosphatase (ALP) ≤2.5 × ULN
- \*\*Renal function:\*\*
- Serum creatinine ≤1.5 × ULN \*\*or\*\* calculated creatinine clearance ≥30 mL/min (Cockcroft-Gault formula)
- \*\*Coagulation function (without anticoagulation therapy):\*\* INR ≤1.5
- Patients of reproductive potential must use effective contraception during the study and for 6 months after the last dose.
Exclusion
- Lesions located at the prostate apex or in areas inaccessible for focal therapy.
- Beaded prostatic calculi or cysts \>1 cm in diameter within the treatment or ultrasound pathway.
- Urethral stricture or presence of metal/other implants in the urethra.
- Prior rectal surgery.
- History of or existing rectal fistula.
- Rectal stenosis preventing transrectal ultrasound.
- Rectal invasion.
- Active severe urinary tract infection.
- Severe cardiovascular or cerebrovascular disease affecting anesthesia/surgery.
- History of hypersensitivity or intolerance to any study drugs.
- Planned concurrent anticancer therapy during the study.
- Prior treatment with second-generation androgen receptor (AR) inhibitors (e.g., apalutamide, enzalutamide, darolutamide), CYP17 inhibitors (e.g., abiraterone acetate, ketoconazole), chemotherapy, immunotherapy, or adjuvant/neoadjuvant therapy.
- Use of herbal products with anti-prostate cancer or PSA-lowering effects (e.g., saw palmetto) within 4 weeks before study treatment.
- History of seizures, medications that lower seizure threshold, or conditions predisposing to seizures within 12 months (including TIA, stroke, or traumatic brain injury with hospitalization).
- Active cardiac disease within 6 months before treatment: severe/unstable angina, myocardial infarction, congestive heart failure (NYHA Class III/IV), or arrhythmia requiring medication.
- Conditions impairing drug absorption (e.g., dysphagia, chronic diarrhea, intestinal obstruction).
- Immunodeficiency (e.g., HIV-positive, congenital/acquired immunodeficiency) or organ transplant history.
- Known brain metastases.
- Other malignancies within 5 years (except cured basal cell carcinoma or cervical carcinoma in situ).
- Concurrent participation in another investigational drug/device trial.
- Poor compliance likely to hinder treatment/follow-up.
- Uncontrolled comorbidities (e.g., hypertension, diabetes, neuropsychiatric disorders) that may compromise safety or confound results, per investigator judgment.
- Any other condition deemed unsuitable for inclusion by the investigator.
