What are the treatment options for locally advanced Melanoma

Treatment Options for Locally Advanced Melanoma

Based on the NCCN Guidelines for Patients: Melanoma (2025), locally advanced melanoma typically refers to stage 3 melanoma, which means the cancer has spread to nearby lymph nodes or skin areas but hasn't reached distant organs. Let me walk you through the main treatment approaches your care team might consider.

Understanding Your Starting Point

First, your doctors will determine whether your melanoma can be completely removed with surgery—this is called resectable disease (able to be removed) versus unresectable/borderline resectable disease (difficult or impossible to remove completely). This distinction is crucial because it shapes your treatment plan.

Treatment for Resectable (Removable) Disease

According to NCCN Guidelines, when locally advanced melanoma can be surgically removed, your initial treatment options typically include:

1. Surgery with Complete Excision

• Removal of all visible cancer with adequate margins (surrounding healthy tissue)
• Often includes removal of affected lymph nodes
• This is typically the first-line approach for resectable disease

2. Neoadjuvant Systemic Therapy

This means receiving drug treatment before surgery to shrink the cancer and make it easier to remove completely. Options include:

• Immunotherapy drugs (checkpoint inhibitors like nivolumab or pembrolizumab)
• Targeted therapy (dabrafenib/trametinib if you have a BRAF V600 mutation—a specific genetic change in your cancer cells)

3. T-VEC (Talimogene Laherparepvec) / Intralesional Therapy

• An injectable immunotherapy delivered directly into the tumor
• Uses a modified virus to stimulate your immune system to attack cancer cells
• Can be used before or instead of surgery in some cases

4. Systemic Therapy Alone

• Immunotherapy or targeted therapy given throughout your body
• Used when surgery isn't the best first option

After Surgery: Adjuvant (Follow-up) Treatment

According to NCCN Guidelines, if surgery successfully removes all visible cancer, your doctor may recommend adjuvant therapy to reduce the risk of recurrence. Preferred options include:

• Nivolumab (Opdivo) - an immunotherapy checkpoint inhibitor
• Pembrolizumab (Keytruda) - another checkpoint inhibitor
• Dabrafenib/trametinib - targeted therapy if you have a BRAF V600 mutation
• Observation - close monitoring without additional treatment (depending on your specific situation)

Treatment for Unresectable/Borderline Resectable Disease

When surgery cannot completely remove the cancer, NCCN Guidelines recommend:

Preferred Initial Approach:

• Systemic therapy (immunotherapy or targeted therapy) as the main treatment

Additional Local Options:

• T-VEC/intralesional therapy (preferred local option)
• Interleukin-2 (IL-2) - an injectable immunotherapy in selected cases
• Radiation therapy - high-energy beams to target tumors
• Isolated Limb Infusion/Perfusion (ILI/ILP) - if melanoma is confined to an arm or leg, a specialized procedure delivering high-dose chemotherapy directly to that limb (only at experienced centers)
• Palliative surgery or local ablation - limited procedures to relieve symptoms

Understanding Immunotherapy vs. Targeted Therapy

Immunotherapy (Checkpoint Inhibitors):

• Helps your immune system recognize and attack cancer cells
• Works by blocking proteins that cancer uses to hide from your immune system
• Examples: nivolumab, pembrolizumab
• Given as infusions (IV) every few weeks, or newer subcutaneous forms every 2-4 weeks

Targeted Therapy:

• Attacks specific genetic mutations in cancer cells
• Only works if your cancer has the BRAF V600 mutation
• Example: dabrafenib/trametinib combination
• Usually taken as pills

Key Questions to Ask Your Oncology Team

To help you engage in shared decision-making about YOUR specific situation:

1. Is my melanoma resectable or unresectable? (Can it be completely removed with surgery?)

2. Do I have a BRAF V600 mutation? (This affects which targeted therapies might work for me)

3. What is your recommended treatment sequence? (Surgery first, or systemic therapy before surgery?)

4. If immunotherapy is recommended, which checkpoint inhibitor do you prefer for my case, and why?

5. What are the expected side effects of my recommended treatment, and how will we manage them?

6. After initial treatment, what adjuvant (follow-up) therapy do you recommend to reduce recurrence risk?

7. Are there clinical trials available for my stage and type of melanoma?

8. How will we monitor my response to treatment? (Imaging, blood tests, physical exams?)

Important Context

According to NCCN Guidelines, locally advanced melanoma is treatable, and more effective treatments have become available in recent years. The combination of surgery with immunotherapy or targeted therapy has significantly improved outcomes for many patients. Your specific treatment plan will depend on:

• Whether your cancer is resectable
• Your genetic testing results (BRAF mutation status)
• Your overall health and ability to tolerate treatments
• Your preferences and values
