Understanding Rising Melanoma Tumor Markers

I appreciate you sharing this concern. Rising tumor markers can understandably feel worrying, so let me help you understand what this generally means and what questions to ask your care team.

What Tumor Markers Tell Us

Tumor markers are substances in your blood that can indicate cancer activity. When melanoma markers are rising, this typically suggests:

  • Increased cancer cell activity — The cancer cells may be producing more of these markers, which can indicate the disease is progressing or becoming more active
  • Possible disease progression — Rising markers often prompt doctors to look more carefully at whether the melanoma is growing or spreading
  • Need for further evaluation — Your oncologist will likely order imaging tests (CT scans, PET scans, or other imaging) to see if there are physical changes in tumors that match the marker rise

How Doctors Think About This

According to the NCCN Guidelines for Patients: Melanoma, when melanoma shows signs of progression or recurrence, oncologists typically:

  1. Confirm with imaging — Blood markers alone don't tell the complete story. Doctors need to see if tumors are actually growing on scans
  2. Assess your current treatment — If you're on treatment, rising markers may mean the current approach isn't working as well as hoped
  3. Consider your stage and location — Whether the cancer is localized, regional (in lymph nodes), or metastatic (spread to distant sites) affects what options make sense next
  4. Evaluate your overall health — Your general fitness and any side effects from current treatment matter for deciding next steps

What This Generally Means for Treatment Decisions

Rising markers typically lead doctors to consider:

  • Changing current therapy — If you're on immunotherapy or targeted therapy, your doctor may switch to a different approach
  • Adding or intensifying treatment — Sometimes combining treatments works better than a single approach
  • Investigating the extent of disease — More detailed imaging helps determine if surgery, radiation, or systemic therapy (drugs) would be most helpful

According to NCCN Guidelines, treatment options for progressive melanoma may include:

  • Immunotherapy (checkpoint inhibitors like nivolumab or pembrolizumab)
  • Targeted therapy (if you have a BRAF mutation, drugs like dabrafenib/trametinib)
  • T-VEC intralesional therapy (injecting treatment directly into tumors)
  • Radiation therapy for specific sites
  • Surgery if tumors are resectable (able to be removed)

Important Questions to Ask Your Oncologist

  1. What specific marker(s) are rising, and by how much? — Different markers have different meanings, and the rate of rise matters
  2. What imaging do you recommend to confirm if the cancer is actually growing? — This is crucial because markers alone don't always mean progression
  3. If the cancer is progressing, what treatment changes do you recommend? — Ask about the pros and cons of each option
  4. Are there clinical trials I should consider? — New treatments are constantly being tested
  5. How often will we check these markers going forward? — This helps you understand the monitoring plan
  6. What symptoms should I watch for in the meantime? — This helps you stay alert to changes

What You Should Know

Rising tumor markers are a signal that deserves attention, but they're not a diagnosis by themselves. Your oncologist needs to correlate them with:

  • Physical exam findings
  • Imaging results
  • Your symptoms (or lack of symptoms)
  • How you're tolerating current treatment

Many patients have rising markers that stabilize with treatment adjustments, and others respond well to different therapeutic approaches. The key is getting a complete picture of what's happening with your cancer.
