Официальное название
Prospective Clinical Study to Identify Secondary Sentinel Lymph Nodes in Patients With N1/N2b Oral Cavity or H&N Skin Cancers Using Patent Blue V and Indocyanine Green Dyes (preReDSeL Study)
Обзор
Head and neck (H\&N) cancer has a poor prognosis and high morbidity with \~50% survival and frequent treatment resistance. Most deaths result from local or loco-regional progression rather than distant metastasis. Lymphatic spread to regional lymph nodes (RLNs), especially with extra-nodal extension (ENE), is a key predictor of poor outcomes. Current imaging techniques often miss micrometastases, leading to extensive but sometimes unnecessary neck treatments. Sentinel lymph node biopsy (SLNB) offers a precise method to detect early spread but is not yet widely adopted. Identifying second-echelon sentinel nodes-those receiving drainage from primary or first-tier nodes-may further refine treatment. The preReDSeL study evaluates the use of dyes (indocyanine green and Patent Blue V) for detecting these nodes. Success could reduce morbidity and guide tailored surgical/radiation therapy. The follow-up ReDSeL study will assess the clinical value of these findings.
Вмешательства
- Препарат Patent blue V dye injection
Patent Blue V dye is injected around the primary tumor. - Препарат Indocyanine green dye injection
Indocyanine green dye is injected inside the metastatic lymph node(s).
Первичные конечные точки
- Percentage of cases where the histopathological analysis of the dyed specimens confirms the presence of a lymph node [Срок оценки: During surgery (from dye-injection until end of surgery)]
- Percentage of cases where the secondary sentinel lymph node status corresponds to the presence of disease in the rest of the dissected lymph nodes based on histopathology analysis [Срок оценки: During surgery (from dye-injection until end of surgery)]
Критерии участия
Критерии включения
- Age ≥18 years
- Operable SCC located in the oral cavity or the skin of the H\&N region, with one or two LNM
- Primary disease
- ECOG performance status 0-2
- Signed study informed consent form for participation
Критерии исключения
- Non-operable tumors or contraindication to surgery
- Previously treated head and neck cancer. Note: neoadjuvant treatment is not an exclusion criterion
- Known hypersensitivity/allergy to triphenylmethane-based (Blue) dyes or to any of their components
- Known hypersensitivity/allergy to indocyanine green or sodium iodide or iodine
- Patients with known hyperthyroidism, thyroid autonomy (e.g., autonomous adenoma), or any thyroid disorder that may lead to increased iodine uptake
- Patients with severe renal impairment (e.g., estimated glomerular filtration rate <30 mL/min/1.73 m²)
- Patients receiving beta-blocker therapy, as these medications may mask or reduce the response to anaphylactic reactions induced by dye injection
- Pregnancy and/or ongoing breastfeeding
- Any reason that would interfere with the patient's well-being and treatment as assessed by the investigator
