Prognosis And Survival For Melanoma Skin Cancer
If you have melanoma skin cancer, you may have questions about your prognosis. A prognosis is the doctors best estimate of how cancer will affect someone and how it will respond to treatment. Prognosis and survival depend on many factors. Only a doctor familiar with your medical history, the type and stage of the cancer, the treatments chosen and the response to treatment can put all of this information together with survival statistics to arrive at a prognosis.
A prognostic factor is an aspect of the cancer or a characteristic of the person that the doctor will consider when making a prognosis. A predictive factor influences how a cancer will respond to a certain treatment. Prognostic and predictive factors are often discussed together. They both play a part in deciding on a treatment plan and a prognosis.
The following are prognostic and predictive factors for melanoma skin cancer.
Treatment Of Metastatic Melanoma
Metastatic melanomas can be difficult to treat. The five-year survival rate for people diagnosed with melanoma that has spread to nearby lymph nodes is 66 percent, according to the American Cancer Society. When cancer has spread to distant parts of the body, there may also be other metastases too small to detect by scans. For people diagnosed with stage 4 melanoma, or melanoma that has spread to distant parts of the body, the five-year survival rate is 27 percent.
For stage 3 and 4 melanomas, the following treatments may be used:
Multiple therapies can be used at any given time, and your care plan is a dynamic process. You and your care team should discuss all the options and decide on a treatment plan. Each treatment has different side effects, and its important to feel fully informed of all the associated risks. Other medications and options may help manage the symptoms of your cancer treatment, so you can live the highest quality of life possible throughout the course of your treatment and disease.
What Are The Symptoms Of Intraocular Melanoma
A small growth may not cause any symptoms. As it grows larger, your symptoms may include:
- Blurry vision or sudden vision loss
- Soreness in an eye, or bulging of the eye
- Flashes or floaters in your vision
- Dark spot on your iris, the colored ring at the front of your eye
- Change in the shape of your pupil, the black circle in the center of your eye
- A change in the way your eye moves or looks
Many of these may be caused by other health problems. So its important to see a healthcare provider if you have these symptoms. Your healthcare provider will do an exam and testing to find out if you have cancer.

Finding Skin Cancer Early
- Do a skin self-examination once a month. Your partner or a close friend can help you check places that are hard to see, such as your scalp and back.
- Have your doctor check any suspicious skin changes. Be sure you see your doctor at least once a year. You may need checkups more often if you have:
- Familial atypical mole and melanoma syndrome, which is an inherited tendency to develop melanoma. Your doctor may need to check you every 4 to 6 months.
- Increased exposure to ultraviolet radiation because of your job, hobbies, or outdoor activities.
- Abnormal moles called atypical moles. These moles aren’t cancerous. But their presence is a warning of an inherited tendency to develop melanoma.
A Trial Of Nivolumab For Melanoma That Can’t Be Removed With Surgery Or Has Spread To Other Parts Of The Body
This trial was looking at a drug called nivolumab for melanoma that cant be removed or has spread to another part of the body. If melanoma cant be removed with surgery or has spread to another part of your body, it is called advanced melanoma.

Dormancy In Metastatic Melanoma
The time period between removal of the primary tumor and subsequent recurrence of disease is referred to as metastatic dormancy. In melanomas, a period of dormancy may end with the emergence of recurrent disease at a metastatic site and only rarely at the site of the primary tumor. Melanomas, as well as some other cancers, such as prostate and some types of breast cancer, often have very protracted courses in which metastatic disease does not manifest until years or even decades after removal of the primary tumor. Clinically localized melanoma can recur after disease-free intervals of 10 years or more . In fact, a subset of melanomas will have ultra-long dormancy with recurrence greater than 20 years later . Other tumor types, such as lung and pancreatic adenocarcinomas tend to follow a much swifter clinical course in which discovery of the primary tumor and subsequent metastasis is often a temporally contiguous event . While these differences in metastasis patterns may in part reflect differences in detection amongst different cancer types, it has also been proposed that such observations suggest that certain tumor types might gain full metastatic competency earlier in tumor progression .
Symptoms If Cancer Has Spread To The Brain
You might have any of the following symptoms if your cancer has spread to your brain:
- weakness of a part of the body
- personality changes or mood changes
- eyesight changes

When Should You Call Your Doctor
The most important warning sign for melanoma is a change in size, shape, or colour of a mole or other skin growth . Call your doctor if you have:
- Any change in a mole, including size, shape, colour, soreness, or pain.
- A bleeding mole.
- A discoloured area under a fingernail or toenail not caused by an injury.
- A general darkening of the skin unrelated to sun exposure.
if you have been diagnosed with melanoma and:
- You have trouble breathing or swallowing.
- You cough up or spit up blood.
- You have blood in your vomit or bowel movement.
- Your urine or bowel movement is black, and the blackness isn’t caused by taking iron or Pepto-Bismol.
What Will Happen After Treatment
Youll be glad when treatment is over. For years after treatment, you will see your cancer doctor. Be sure to go to all of these follow-up visits. You will have exams, blood tests, and maybe other tests to see if the cancer has come back.
At first, your visits may be every few months. Then, the longer youre cancer-free, the less often the visits are needed. After 5 years, they may be done once a year.
Having cancer and dealing with treatment can be hard, but it can also be a time to look at your life in new ways. You might be thinking about how to improve your health. Call us at 1-800-227-2345 or talk to your cancer care team to find out what you can do to feel better.
You cant change the fact that you have cancer. What you can change is how you live the rest of your life making healthy choices and feeling as good as you can.

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.

What Else Should I Know About Treatment For Advanced Melanoma
Thanks to research breakthroughs, more patients diagnosed with advanced melanoma are living longer some for years.
Because these breakthrough are relatively recent, its important to:
Work with a team of melanoma specialists.
Ask your melanoma specialists if any of the newer treatments are appropriate for you.
Realize that no one treatment works for everyone, so you may need to try different treatments or combine treatments.
Researchers continue to study advanced melanoma, and next-generation treatments are now being studied in clinical trials. If you want to know whether you are a match for a trial, you can find out if there are any relevant trials at, Clinical Trial Finder.

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.

How Is Melanoma Staged
Melanoma is divided into 4 stages based on the depth of the primary tumor and how far the cancer has spread from its starting point. Melanoma staging system helps to identify the best treatment method for individual cases and also helps to identify the prognosis. In situ melanomas have an excellent prognosis after surgical excision with a sufficient surgical margin. Invasive melanomas are far more serious. Breslow thickness is the depth of the melanoma calculated perpendicularly from the skin surface, specifically from the stratum granulosum of the epidermis to the lower-most level of the melanoma .
Damage To The Muscles Nerves And Bones
If melanoma goes untreated long enough, there are instances where the it may grow deeply enough to affect muscle, says Lucas. As far as it goes down, we have to remove it if it involves the muscle, it has to go. Sometimes skin cancers can go so deep they can even go into bone.
The temporal branch allows you to raise your eyebrows, says Lucas. The surgeon may have to take some of those nerves to remove the cancer. In that situation, the patient may not be able to raise their eyebrow after the surgery, and that can be a permanent change, she says.
What About Other Treatments I Hear About
When you have cancer you might hear about other ways to treat the cancer or treat your symptoms. These may not always be standard medical treatments. These treatments may be vitamins, herbs, special diets, and other things. You may wonder about these treatments.
Some of these are known to help, but many have not been tested. Some have been shown not to help. A few have even been found to be harmful. Talk to your doctor about anything youre thinking about using, whether its a vitamin, a diet, or anything else.
Key Points About Intraocular Melanoma
- Intraocular melanoma is cancer that starts in the melanocytes in your eyes.
- Its rare, but it’s still the most common type of cancer of the eye in adults.
- Risk factors for it are being older and having fair skin and light-colored eyes.
- Symptoms may include blurry vision, eye soreness, or floaters in your vision.
- Exposure to UV light is linked to this cancer. Protect your eyes with sunglasses with 99% to 100% ultraviolet A and B protection.
- Treatments for this cancer include surgery, radiation, and photocoagulation.

Has My Melanoma Spread
Author: Vanessa Ngan, Staff Writer Copy Editor: Clare Morrison Chief Editor: Dr Amanda Oakley, Dermatologist, Hamilton, New Zealand, October 2013. About Melanoma is sponsored by the New Zealand Dermatological Society Incorporated.
What happens next depends very much on how deeply your melanoma has grown into the skin and whether or not melanoma cancer cells have spread to other parts of your body. Your pathology report refers to this as the pathological stage of melanoma and it helps in planning the next steps.
Your doctor will examine your lymph nodes. If they are enlarged, a sample may be taken using a fine needle .
If they are not enlarged, sentinel node biopsy may be recommended to find out if melanoma cells have spread to the lymph nodes.
What Is Choroidal Melanoma
Choroidal melanoma is a cancer that affects part of the eye. It develops in the choroid, the sponge-like membrane at the back of the eye between the sclera and the retina. The choroid is rich in blood vessels and supplies nutrients to the retina.
Over time, many choroidal melanomas enlarge and cause the retina to detach. This can lead to vision loss. The tumors also can spread to other parts of the body. The liver is the most common site for metastasis. If it spreads, this cancer can be fatal.
Although choroidal melanoma is rare, it is the most common eye cancer in adults. It usually occurs in people who are middle-aged or older.
Melanomas usually occur in the skin. But they can also develop in places where certain cells contain the pigment melanin. The choroid is one such example.

Melanoma Symptoms And Signs
Melanoma is a type of skin cancer that forms in pigment-forming cells . Melanoma is the most serious type of skin cancer. Rarely, melanomas can be found in other areas of the body that contain pigment-forming cells, including the eye, the tissues around the brain and spinal cord, or the digestive tract. Melanomas of the skin produce changes in the appearance of the skin, but these changes can sometimes be seen with other skin conditions. The characteristic symptoms include a change in an existing mole or new mole with asymmetric borders, uneven coloring, increasing size, scaling, or itching. Melanomas are typically not painful. It is always important to seek medical advice when you develop a new pigmented spot on the skin or have a mole that is growing or changing.
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
