Comparing Index lymph node resection with Therapeutic lymph node dissection for stage III cutaneous melanoma

Exclusion

• −Active Hepatitis B (defined as Hepatitis B surface antigen \[HBsAg\] reactive) or Hepatitis C virus (defined as HCV RNA \[qualitative\] is detected) infection. Note: no testing for Hepatitis B and Hepatitis C is required unless mandated by local health authority.
• −Has a known history of Human Immunodeficiency Virus (HIV). Note: no testing for HIV is required unless mandated by local health authority.
• −Uveal or mucosal melanoma.
• −Isolated satellite or in-transit metastases only (without any cytological or histological proven lymph node involvement).
• −Involvement of any lymph node basin other than groin, axilla or neck. Concurrent popliteal, epitrochlear or triangular intermuscular space (TIS) nodes permitted, as long as fully resectable.
• −Clinical or radiographic evidence of distant metastasis (any AJCC 8th ed M Stage).
• −Previous radiotherapy to the same nodal basin.
• −Any contraindication to the administration of nivolumab, ipilimumab, pembrolizumab or relatlimab per regulatory-approved product information and / or medical oncologist.
• −Known additional malignancies (unless adequately treated) active within the previous 3 years, except for locally curable cancers that have been apparently cured. The following malignancies, if undergone successful definitive resection or curative treatment, are permitted:
• −Basal cell carcinoma of the skin
• −Squamous cell carcinoma of the skin
• −Carcinoma in situ (e.g. breast carcinoma, cervical cancer in situ, but excluding carcinoma in situ of the bladder) that have undergone potentially curative therapy
• −Prostatic intraepithelial neoplasia
• −In situ melanoma
• −Atypical melanocytic hyperplasia
• −Stage I melanoma
• −Other malignancies for which the patient has been disease free for 3 years, not requiring active anti-cancer therapy.
• −An active autoimmune disease or a requirement for chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 14 days prior to the first dose of study treatment. The following are permitted:
• −Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc)
• −Inhaled or intranasal corticosteroids (with minimal systemic absorption) may be continued if patient is on a stable dose
• −Non-absorbed intra-articular steroid injections.
• −Has had an allogenic tissue/solid organ transplant.
• −Concurrent medical or social conditions that may prevent the patient from attending assessments or procedures per schedule.
• −Pregnant or breastfeeding females.
• −Previous history of lymph node surgery to the same nodal basin, that was more extensive than a sentinel lymph node biopsy (SLNB).
• −Prior anti-PD-1, CTLA-4, PDL-1 or LAG 3 antibody exposure, or an agent directed to another stimulatory or co-inhibitory T-cell receptor for any disease or any chemotherapy or experimental local or systemic drug treatment.
• −A plan to administer targeted therapy or any non-checkpoint inhibitor immunotherapy, or any intralesional therapy for melanoma in the neoadjuvant setting.
• −A plan to administer any experimental immunotherapy as part of a clinical trialInterventional studyA study where participants are given something to see what happens.Read more → in the neoadjuvant setting.
