# Alternative treatment approaches in metastatic melanoma
In metastatic melanoma, some patients seek complementary or alternative treatments alongside or instead of standard medical care. Below are various approaches described, with honest indication of what is known about their effectiveness.
Herbal Extracts and Plant-Based Substances
Various herbs are being investigated for possible activity against melanoma cells in laboratory conditions. Examples include extracts from Danshen (Chinese sage), isoginkgetin from ginkgo, and other traditional plant substances.
ResearchediPositive results in clinical studies, not yet standard treatment
These substances have shown indications in cell culture studies and animal research of possible inhibitory effects on melanoma cell growth or induction of cell programming to death processes (autophagy). However, it is unknown whether these effects occur in the human body, in what quantities, or how safe they are alongside standard treatments. Clinical trials in humans with metastatic melanoma are limited. These agents are not registered as medicines in the Netherlands and their purity and composition can vary greatly.
**Important:** use without medical supervision can disrupt the immune system and interfere with immunotherapy (checkpoint inhibitors), which can be harmful.
Traditional herbal mixtures (TCM formulations)
Some traditional Chinese medicine (TCM) formulations are being tested in research settings, for example in combination with chemotherapy.
ExperimentaliOngoing in study setting, outcome still unknown
Studies suggest that certain TCM mixtures may possibly enhance the effect of certain chemotherapies and influence the tumor microenvironment. However, these are very early studies, mostly in animal models. For metastatic melanoma, reliable clinical trials in patients are lacking. The effectiveness, safety, and optimal dosing for humans are unknown. These treatments are not recognized by Dutch medical guidelines.
Integrative naturopathic approaches
This includes combinations of nutritional supplements, herbal agents, dietary modifications, and lifestyle interventions, sometimes as a supplement to or replacement for medical therapy.
UnproveniNo scientific evidence that it works
To date, integrative naturopathic treatments for metastatic melanoma have only been described in a few case reports (two patients per report), not in randomized controlled trials. These reports can be informative, but provide insufficient evidence that an approach is effective or safe for a broader population. Without adequate medical monitoring, supplement products can interact with each other or with standard treatments (immunotherapy, targeted therapy, chemotherapy) with serious consequences.
Nutrition and dietary supplements
Some patients make dietary changes or take additional vitamins and minerals, thinking this will help their immune system.
UnproveniNo scientific evidence that it works
Healthy diet is important for general well-being and immune function, but there is no clear evidence that specific nutritional supplements can stop or cure metastatic melanoma. Although some nutrients (such as vitamin D) play a role in immune response, it is unclear what quantities are safe and meaningful during active cancer therapy. Certain supplements can affect blood clotting, inflammatory responses, or drug metabolism, causing standard treatments to work less well or resulting in more side effects.
Acupuncture
Acupuncture is sometimes offered to support well-being, energy management, and symptom relief in cancer.
UnproveniNo scientific evidence that it works
For metastatic melanoma in particular, there is no scientific evidence of effectiveness against the disease itself. Acupuncture may in some cases provide support with certain side effects of standard treatments (pain, fatigue), but this is not a substitute for tumor-directed therapy. In patients on anticoagulants or with low platelets, acupuncture can carry risks.
Homeopathy
Homeopathic preparations (highly diluted substances) are sometimes offered as supportive or alternative treatment.
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
Homeopathic remedies are not effective against cancer diseases according to multiple large studies. For a serious disease like metastatic melanoma, where rapid medical intervention is crucial, relying on homeopathy can cost valuable time. Additionally, some homeopathic preparations may contain impurities or interfere with medications.
Vitamins in high doses (orthomolecular medicine)
The use of very high doses of vitamins (such as vitamin C, D, or certain B vitamins) is sometimes suggested to support cancer treatment.
UnproveniNo scientific evidence that it works
While normal amounts of vitamins are necessary, evidence for very high doses in cancer is limited and contradictory. Some high doses can interfere with chemotherapy or immunotherapy, possibly by blocking oxidative processes that are actually important for their effectiveness. This risk is more serious than potential benefits.
Immune-stimulating natural products (particularly mushrooms, probiotics)
Certain mushroom extracts, food bacteria, and plant components are being tested for possible effects on immune activation.
ResearchediPositive results in clinical studies, not yet standard treatment
In laboratory studies, certain mushroom components and bacterial preparations have shown signs of immune-stimulating capacity. However, clinical applications in metastatic melanoma have not been established. Moreover: in patients receiving immunotherapy (checkpoint inhibitors), these substances can trigger unexpected immune reactions, which can be dangerous. Adding them on your own without permission from your treating physician is not safe.
Dietary changes (vegan, ketogenic, intermittent fasting)
Certain dietary patterns are sometimes suggested as supportive or tumor-reducing.
UnproveniNo scientific evidence that it works
Although healthy eating generally contributes to well-being, there is no scientific evidence that specific diets (such as ketogenic or intermittent fasting) can cure or even reduce metastatic melanoma. During active cancer treatment, insufficient nutritional intake can actually be harmful due to loss of muscle mass and weakening of the immune system. Diets should be tailored to individual needs under the guidance of a nutrition specialist.

**Important warnings:**
- **Not a wise replacement:** using alternative treatments instead of proven therapies (immunotherapy, targeted therapy, chemotherapy) can have serious consequences and likely shortens survival.
- **Interactions:** many natural products interfere with standard treatments and can cause toxicity or ineffectiveness.
- **No regulation:** alternative remedies are often not strictly controlled for purity or safety.
- **Communication with physicians:** always discuss any supplements, herbs, or diets you are considering with your treating physician.
