Where Does Skin Melanoma Metastasis To

Prognosis For Metastatic Melanoma

Until recent years, a metastatic melanoma prognosis gave patients very little reason to hope.

But since 2011, physicians have had access to remarkable new drugs that are helping many patients live significantly longer.

Many patients with malignant melanoma are responding to the new treatments, extending their lives by months and years. Some are even going into long-term remission.

The currently available data puts the five-year survival rate for stage 3 cancer at between 40 and 78 percent , and for stage 4 melanoma at 15 to 20 percent.

But those numbers are expected to go up now that doctors are treating more and more patients with new drugs.

A study published in March 2017 in the Journal of Cancer Research and Clinical Oncology focused on patients with stage 4 metastatic melanoma and found that new drugs available since 2011 were, in fact, extending lives.

Three-year survival for patients who entered stage 4 in 2013 and 2014 was 37 percent, compared with in March 2017 those who entered stage 4 in 2011 and 2012 .

When Melanoma Can’t Be Cured

If your cancer has spread and it is not possible to cure it by surgery, your doctor may still recommend treatment. In this case, treatment may help to relieve symptoms, might make you feel better and may allow you to live longer.

Whether or not you choose to have anti-cancer treatment, symptoms can still be controlled. For example, if you have pain, there are effective treatments for this.

General practitioners, specialists and palliative care teams in hospitals all play important roles in helping people with cancer.

How Do You Get Rid Of Melanoma Without Surgery

Radiation therapy. This treatment uses high-powered energy beams, such as X-rays and protons, to kill cancer cells. Radiation therapy may be directed to the lymph nodes if the melanoma has spread there. Radiation therapy can also be used to treat melanomas that cant be removed completely with surgery.

Symptoms Of Metastatic Melanoma Other Than A Mole

Other symptoms of this type of cancer may not appear until a later stage, when the melanoma has metastasized to another area of the body. Metastatic melanoma most often spreads to the lymph nodes, brain, bones, liver or lungs, and the additional symptoms experienced at this late stage will depend on where the melanoma has spread. For example:

• Lungs A persistent cough or shortness of breath
• Brain Headaches or seizures
• Lymph nodes Swelling of the lymph nodes
• Liver Loss of appetite or unexplained weight loss
• Bone Bone pain or unusual fractures

How Does The Doctor Know I Have Skin Cancer

Basal and squamous skin cancer may look like:

• Flat, firm, pale or yellow areas that look a lot like a scar
• Raised reddish patches that might itch
• Rough or scaly red patches, which might crust or bleed
• Small, pink or red, shiny, pearly bumps, which might have blue, brown, or black areas
• Pink growths or lumps with raised edges and a lower center
• Open sores that dont heal, or that heal and then come back
• Wart-like growths

Red Flag #: Abdominal Pain And Tenderness

Early on, there may be no noticeable symptoms that melanoma has spread to the liver. When symptoms do show up, they commonly include an enlarged, hard, or tender liver and pain in the upper right area of your abdomen, just below your ribs. Other signs cancer has spread to the liver are similar to symptoms of liver disease: fluid buildup in the belly and yellowing of the skin and eyes .

How Does The Doctor Know I Have Melanoma

A new spot on your skin or a spot thats changing in size, shape, or color may be a warning sign of melanoma. If you have any of these changes, have your skin checked by a doctor.

The doctor will ask you questions about when the spot on your skin first showed up and if it has changed in size or the way it looks. The rest of your skin will be checked. During the exam your doctor will check the size, shape, color and texture of any skin changes. If signs are pointing to melanoma, more tests will be done.

Melanoma Occurrence Staging & Detection

Histologic and clinical findings that classify the tumor as American Joint Committee on Cancer stage III

Microscopic, immunohistochemistry positive sentinel lymph node, clinically and pathogically positive lymph node and peritumoral and in transit metastasis .

Factors that are predictive of metastasis in the primary

Mitotic rate, vascular invasion, absence of a tumor-infiltrating lymphocyte host response and microsatellites, whose presence upgrades the melanoma to American Joint Committee on Cancer stage IIIc and are essentially in-transit metastasis.

Since metastasis is the most important predictor of the patient’s prognosis, there is a lot of effort directed at unequivocal determination of their presence in the adjacent epidermis, sentinel lymph nodes, circulation and distant sites .

Symptoms If Cancer Has Spread To The Bone

You might have any of the following symptoms if your cancer has spread to the bones:

• pain from breakdown of the bone the pain is continuous and people often describe it as gnawing
• backache, which gets worse despite resting
• weaker bones they can break more easily
• raised blood calcium , which can cause dehydration, confusion, sickness, tummy pain and constipation
• low levels of blood cells blood cells are made in the bone marrow and can be crowded out by the cancer cells, causing anaemia, increased risk of infection, bruising and bleeding

Cancer in the spinal bones can cause pressure on the spinal cord. If it isn’t treated, it can lead to weakness in your legs, numbness, paralysis and loss of bladder and bowel control . This is called spinal cord compression. It is an emergency so if you have these symptoms, you need to contact your cancer specialist straight away or go to the accident and emergency department.

How Common Is Melanoma

Melanoma accounts for only about 1% of all skin cancers, but causes the great majority of skin cancer-related deaths. Its one of the most common cancers in young people under 30, especially in young women.

Melanoma incidence has dramatically increased over the past 30 years. Its widely accepted that increasing levels of ultraviolet exposure are one of the main reasons for this rapid rise in the number of melanoma cases.

Symptoms If Cancer Has Spread To The Lymph Nodes

Lymph nodes are part of a system of tubes and glands in the body that filters body fluids and fights infection.

The most common symptom if cancer has spread to the lymph nodes is that they feel hard or swollen. Swollen lymph nodes in the neck area can make it hard to swallow.

Cancer cells can also stop lymph fluid from draining away. This might lead to swelling in the neck or face due to fluid buildup in that area. The swelling is called lymphoedema.

When Should I Call My Doctor

You should have a skin examination by a doctor if you have any of the following:

• A personal history of skin cancer or atypical moles .
• A family history of skin cancer.
• A history of intense sun exposure as a young person and painful or blistering sunburns.
• New or numerous large moles.
• A mole that changes in size, color or shape.
• Any mole that itches, bleeds or is tender.

A note from Cleveland Clinic

Receiving a diagnosis of melanoma can be scary. Watch your skin and moles for any changes and seeing your doctor regularly for skin examinations, especially if youre fair-skinned, will give you the best chances for catching melanoma early when its most treatable.

Red Flag #: Bone Pain Or Fractures

The bones are considered a late-stage site of melanoma metastasestypically, it doesnt spread to the bones until its already spread to another area of the body first. Melanoma can cause pain in the bones where its spread, and some peoplethose with very little body fat covering their bonesmay be able to feel a lump or mass. Metastatic melanoma can also weaken the bones, making them fracture or break very easily. This is most common in the arms, legs, and spine. If you feel any sharp, sudden, or new pains that wont go away, talk to your doctor.

Different Kinds Of Skin Cancer

There are many types of skin cancer. Some are very rare. Your doctor can tell you more about the type you have.

The two most common kinds of skin cancers are:

• Basal cell cancer, which starts in the lowest layer of the skin
• Squamous cell cancer, which starts in the top layer of the skin

Another kind of skin cancer is called melanoma. These cancers start from the color-making cells of the skin . You can read about melanoma in If You Have Melanoma Skin Cancer.

Red Flag #: Headaches Or Visual Changes

Just like the liver, not everyone will notice symptoms of melanoma spreading to the brain. But when symptoms do show up, its usually in the form of headaches, problems with eyesight, paralysis on one side of the body, or seizures. If someone simply has a headache, that doesnt mean they have advanced stage melanoma, Dr. Yushak says. But if its a headache thats not going away after a week, and you never have headaches, then thats something that definitely needs to be checked out.

Risk Of Further Melanomas

Most people treated for early melanoma do not have further trouble with the disease. However, when there is a chance that the melanoma may have spread to other parts of your body, you will need regular check-ups.

Your doctor will decide how often you will need check-ups everyone is different. They will become less frequent if you have no further problems.

After treatment for melanoma it is important to limit exposure to the sun’s UV radiation. A combination of sun protection measures should be used during sun protection times .

As biological family members usually share similar traits, your family members may also have an increased risk of developing melanoma and other skin cancers. They can reduce their risk by spending less time in the sun and using a combination of sun protection measures during sun protection times.

It is important to monitor your skin regularly and if you notice any changes in your skin, or enlarged lymph glands near to where you had the cancer, see your specialist as soon as possible.

Mouse Models Mimic Metastasis Of Human Melanoma

Metastasis is a highly inefficient process in that the vast majority of cancer cells that try to migrate die before they ever have an opportunity to form a tumor, Dr. Morrison said.

Dr. Morrisons team found previously that one factor limiting the survival of melanoma cells circulating in the blood is that the cells experience a high level of oxidative stress. Oxidative stressan imbalance between free radicals and antioxidants in the bodycauses chemical reactions that can damage proteins, DNA, and lipids in cells and disrupt normal cell processes. However, precisely how oxidative stress kills circulating melanoma cells was not known.

For their studies, the team used a mouse model of metastasis created by transplanting melanoma cells from humans beneath the skin of specially bred mice with weakened immune systems. These mice were used to avoid having the transplanted human cells seen as foreign and attacked by the immune system. The team also used a second mouse model created by transplanting mouse melanoma cells into mice with normal immune systems.

Comparing these two mouse models let the researchers control for potential effects of the immune system on the spread of melanoma, Dr. Salnikow explained.

The study was supported in part by NCIs Patient-Derived Models of Cancer program, which promotes the development of animal models that more closely mirror how tumor cells behave in humans.

Comparing Metastatic Melanoma Cells In Lymph Versus Blood

Most studies of cancer cell metastasis in people have focused on cells circulating in the blood. Thats because its much easier to collect patient blood samples than it is to collect samples of lymph, the clear fluid that carries immune cells through vessels of the lymphatic system, Dr. Morrison said.

Dr. Morrisons team found that human melanoma cells injected into lymph nodes in the mice were more likely to form distant tumors than melanoma cells injected into blood.

To study the role of lymph in metastasis, lead investigator Jessalyn Ubellacker, Ph.D., a postdoctoral researcher in Dr. Morrisons lab, figured out how to collect melanoma cells from lymph in mice. This allowed the team to do the first side-by-side comparison of melanoma cells spreading through lymph and through blood in the same animal, Dr. Morrison said.

Next the team found that melanoma cells in lymph experienced less oxidative stress than melanoma cells in blood. That offered a potential explanation for why melanoma cells from lymph nodes were surviving better and better able to form a tumor, Dr. Morrison said.

Further experiments showed that melanoma cells in blood are vulnerable to ferroptosisa form of cell death that occurs when lipids damaged by oxidative stress build up in the outer membrane of a cell. By contrast, melanoma cells from lymph nodes were protected from ferroptosis.

Earlier Detection Methods Are Needed

Our findings highlight the need for earlier detection of cancer, Dr. Curtis said.

Cancer researchers are already exploring noninvasive methods that could detect cancer at an early stage by analyzing tumor cells, or pieces of DNA from tumor cells, that have escaped from the original tumor and are found in the blood.

This approach, often called a liquid biopsy, could help doctors identify patients at risk for metastasis and treat them with chemotherapy or targeted therapies, if available, to try to eliminate metastatic cells that have spread in the body before surgery, Dr. Boudreau said.

This is early-stage research, but it gives us the first quantitative evidence that metastasis can occur exceedingly early, while also providing clues as to how to identify individuals who are at risk of metastasis, Dr. Curtis said.

Before the new results can be used to guide patient care, the researchers will need to look at a much larger group of patients, to see how consistent their findings are, Dr. Boudreau said.

Indeed, Dr. Curtis said, her team plans to extend their analysis to more patients. The biggest task, she said, will be to follow patients with earlier-stage colorectal cancer and investigate whether these specific combinations of mutations are indeed predictive of disease progression. And then, if thats true, we will have a rationale to go forward with clinical studies.

Temporal And Spatial Complexity Of Metastasis

Metastasis involves a series of steps which must be completed before the emergence of clinically meaningful metastatic disease . These steps are further complicated by additional observations from human melanoma patients which add temporal and spatial complexity to metastasis. Many melanoma patients are cured after excision of their primary tumor however, some are not, and will have disease recurrence. Melanoma recurs less frequently at the site of the original primary tumor, instead more commonly recurring at different sites in the body as metastatic lesions. These recurrence patterns suggest that melanoma cells had already spread before excision of the primary tumor, even though this spread might not have been clinically apparent at that time. In melanoma patients, metastatic recurrence can occur within a relatively short period of time, but takes > 5 years in about 40% of patients., , , The period in between initial excision of the primary tumor and subsequent metastatic recurrence is often referred to as metastatic dormancy, where previously disseminated tumor cells are thought to persist in a relatively non-proliferative state.

Symptoms Of Advanced Melanoma

The symptoms of advanced melanoma depend on where the melanoma has spread to.

Symptoms can begin years after the original melanoma was removed. For some people the melanoma may be advanced when it is first diagnosed.

A small number of people who have not had melanoma before may develop symptoms of secondary melanoma. They may have had no previous signs of melanoma and no abnormal-looking moles.

The general symptoms of advanced melanoma can include:

• weight loss
• loss of appetite
• feeling very tired .

If you are worried about advanced melanoma, we have more information about the signs and symptoms.

Common Places For Melanoma To Spread

Melanoma can spread from the original site on your skin and form a tumor in any organ or body tissue, but its most likely to metastasize to the lymph nodes, liver, brain, lungs, and less commonly, the bones. Melanoma really likes the brain and the liver, says Lisa Zaba, M.D., dermatologic oncologist at Stanford Medical Center in San Jose, CA. If you notice any of the following red flags, it might mean your melanoma has spread and warrants a call to your doctor right away.
