Molecular Changes Associated With Malignant Melanoma

After the melanoma spreads or metastasizes from its origin into other cutaneous or subcutaneous tissues, the response rate to treatment plummets to approximately 520%, and the 10-year survival rate becomes only about 10% . Metastatic melanoma has been especially difficult to treat, showing low cure and survival rates after surgical resection and radiation therapy . At the cellular level, cancer cells possess distinguishing molecular properties that allow for apoptosis evasion, limitless growth potential without the need for growth factors, angiogenesis, and metastasis . Identifying the specific molecular changes that allow melanoma cells to have a growth and survival advantage over others may allow for the development of more effective targeted therapies that can improve the prognosis of melanoma patients.

BRAF

Further research has revealed that the early stage of melanoma formation, known as the radial growth phase, exhibits a low 10% BRAF mutation rate, which supports the hypothesis that BRAF does not play a part in melanoma initiation . At the same time, 6070% of vertical growth lesions and metastasized melanomas possess BRAF mutations, which suggests that this oncogenic mutation may be involved in cancer progression . The existence of activating BRAF in metastasized melanoma is consistent with the proposed BRAF function of cell growth promotion. The high prevalence of the BRAFV600E mutation in melanoma patients makes this a prime target for anti-melanoma therapeutics.

What Happens If Precancers Go Untreated

As the name suggests, precancers are damaged skin cells that arent considered cancerous, but if they are left untreated, these lesions are at high risk to become skin cancer. There are two main types of precancerous skin conditions: actinic keratosis and dysplastic nevi. Actinic keratosis looks like a rough, scaly patch of the skin that is usually red or brown. This condition may develop into squamous cell carcinoma if left untreated.

Nevi are moles, and dysplastic nevi is a term that means a mole is abnormal. Dysplastic nevi may develop into melanoma without proper treatment. While precancerous skin cancers are not malignant on their own, the potential to develop into life-threatening forms of this condition means they need to be evaluated regularly.

Diagnosing Squamous Cell Carcinoma

The main way to diagnose squamous cell carcinoma is with a biopsy. This involves having a small piece of tissue removed from the suspicious area and examined in a laboratory.

In the laboratory, a pathologist will examine the tissue under a microscope to determine if it is a skin cancer. He or she will also stage the cancer by the number of abnormal cells, their thickness, and the depth of penetration into the skin. The higher the stage of the tumor, the greater the chance it could spread to other parts of the body.

Squamous cell carcinoma on sun-exposed areas of skin usually does not spread. However, squamous cell carcinoma of the lip, vulva, and penis are more likely to spread. Contact your doctor about any sore in these areas that does not go away after several weeks.

What Stages Have To Do With Cancer Spread

Types of Skin Cancer

Cancers are staged according to tumor size and how far it has spread at the time of diagnosis. Stages help doctors decide which treatments are most likely to work and give a general outlook.

There are different types of staging systems and some are specific to certain types of cancer. The following are the basic stages of cancer:

  • In situ. Precancerous cells have been found, but they havent spread to surrounding tissue.
  • Localized. Cancerous cells havent spread beyond where they started.
  • Regional. Cancer has spread to nearby lymph nodes, tissues, or organs.
  • Distant. Cancer has reached distant organs or tissues.
  • Unknown. Theres not enough information to determine the stage.
  • Stage 0 or CIS. Abnormal cells have been found but have not spread into surrounding tissue. This is also called precancer.
  • Stages 1, 2, and 3. The diagnosis of cancer is confirmed. The numbers represent how large the primary tumor has grown and how far the cancer has spread.
  • Stage 4. Cancer has metastasized to distant parts of the body.

Your pathology report may use the TNM staging system, which provides more detailed information as follows:

T: Size of primary tumor

  • TX: primary tumor cant be measured
  • T0: primary tumor cant be located
  • T1, T2, T3, T4: describes the size of the primary tumor and how far it may have grown into surrounding tissue

N: Number of regional lymph nodes affected by cancer

M: Whether cancer has metastasized or not

Tests That May Be Done

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 or feels. 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 skin cancer, more tests will be done.

Skin biopsy

In a biopsy, the doctor takes out a small piece of tissue to check it for cancer cells. A biopsy is the only way to tell for sure if you have skin cancer and what kind it is.

There are many types of skin biopsies. Ask your doctor what kind you will need. Each type has pros and cons. The choice of which type to use depends on your own case.

In rare cases basal and squamous cell skin cancer can spread to the nearby lymph nodes Ask your doctor if your lymph nodes will be tested.

Basal and squamous cell cancers don’t often spread to other parts of the body. But if your doctor thinks your skin cancer might spread, you might need imaging tests, such as MRI or CT scans.

How Fast Does Melanoma Spread

Melanoma is a deadly form of skin cancer because of its ability to metastasize to local lymph nodes and other organs. It is estimated that melanoma kills, on average, over 10,000 people in the United States every year.

The first sign of flat melanoma is usually a new spot or an existing mole or freckle that changes in appearance. Some changes can include:

  • A spot that has grown in size
  • A spot where the edges are looking irregular versus smooth and even
  • A spot that has a range of colors such as brown, black, blue, red, white or light gray.
  • A spot that has become itchy or is bleeding

According to Dr. Andrew Duncanson, board-certified dermatologist at Forefront Dermatology, It is important to know that melanoma can appear on areas of the skin not normally exposed to the sun such as under the arm, chest, and buttocks. It can also appear in areas that you are not able to see easily on your own including the ears, scalp, back of legs, and bottom of feet. I always recommend to my patients to look for the ugly duckling spot the new spot that doesnt look like any others. Additionally, ask a family member to look over the hard to see areas monthly, while also getting an annual skin cancer exam by a board-certified dermatologist to detect skin cancer early.

Different Types Of Cancer Start In The Skin

Skin cancer may form in basal cells or squamous cells. Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer. They are also called nonmelanoma skin cancer. Actinic keratosis is a skin condition that sometimes becomes squamous cell carcinoma.

Melanoma is less common than basal cell carcinoma or squamous cell carcinoma. It is more likely to invade nearby tissues and spread to other parts of the body.

This summary is about basal cell carcinoma, squamous cell carcinoma of the skin, and actinic keratosis. See the following PDQ summaries for information on melanoma and other kinds of cancer that affect the skin:

What Are The Stages Of Squamous Cell Carcinoma

How Skin Cancer Spreads-Mayo Clinic

Squamous cell carcinoma is classified into the following stages, which are partly based on how far the cancer has spread throughout the body:

  • Stage 0 Squamous cell carcinoma develops in the squamous cells, which are located in the epidermis . During Stage 0, the cancer hasnt spread beyond the epidermis.
  • Stage 1 When squamous cell carcinoma progresses to Stage 1, it means that the cancer has spread deeper into the skin, but not into any lymph nodes or healthy tissues.
  • Stage 2 A Stage 2 classification means that, in addition to progressing deeper into the skin, the cancer also displays at least one high-risk feature. This might include metastasizing to the lower skin layers or the nerves. However, at this stage, the cancer still hasnt spread to lymph nodes or healthy tissues.
  • Stage 3 Once squamous cell carcinoma reaches Stage 3, the cancer has spread into lymph nodes but not any other tissues or organs.
  • Stage 4 This is the final stage of squamous cell carcinoma, where the cancer has spread to at least one distant organ, whether that be the brain, the lungs or a separate area of skin.

If you think you might have squamous cell carcinoma, its important to seek prompt medical attention to minimize the risk of cancer spread.

Biological Therapies And Melanoma

Biological therapies are treatments using substances made naturally by the body. Some of these treatments are called immunotherapy because they help the immune system fight the cancer, or they occur naturally as part of the immune system. There are many biological therapies being researched and trialled, which in the future may help treat people with melanoma. They include monoclonal antibodies and vaccine therapy.

How Serious Is My Cancer

If you have skin cancer, the doctor will want to find out how far it has spread. This is called staging.

Basal and squamous cell skin cancers don’t spread as often as some other types of cancer, so the exact stage might not be too important. Still, your doctor might want to find out the stage of your cancer to help decide what type of treatment is best for you.

The stage describes the growth or spread of the cancer through the skin. It also tells if the cancer has spread to other parts of your body that are close by or farther away.

Your cancer can be stage 0, 1, 2, 3, or 4. The lower the number, the less the cancer has spread. A higher number, like stage 4, means a more serious cancer that has spread beyond the skin. Be sure to ask the doctor about the cancer stage and what it means for you.

Other things can also help you and your doctor decide how to treat your cancer, such as:

  • Where the cancer is on your body
  • How fast the cancer has been growing
  • If the cancer is causing symptoms, such as being painful or itchy
  • If the cancer is in a place that was already treated with radiation
  • If you have a weakened immune system

What Happens If Merkel Cell Carcinoma Is Left Untreated

Merkel cell carcinoma is a rare but aggressive and potentially fatal form of skin cancer. It typically affects people above the age of 50 and those who have weakened immune systems. In most cases, Merkel cell carcinoma begins as a skin-toned growth that may bleed easily. The bumps or nodules may also have blue, purple, or red coloring. Because the Merkle cells are near nerve endings, this form of cancer has numerous health risks, and if left untreated, Merkle cell cancer may spread to the brain, lungs, or bones, becoming fatal.

Complementary And Alternative Treatments

Hospitals see rapid rise in skin cancer

It’s common for people with cancer to seek out complementary or alternative treatments. When used alongside your conventional cancer treatment, some of these therapies can make you feel better and improve your quality of life. Others may not be so helpful and in some cases may be harmful. It is important to tell all your healthcare professionals about any complementary medicines you are taking. Never stop taking your conventional treatment without consulting your doctor first.All treatments can have side effects. These days, new treatments are available that can help to make many side effects much less severe than they were in the past.

Everyone Is At Risk For Skin Cancer How Much Do You Know About Skin Cancer

Basal cell carcinoma and squamous cell carcinoma
  • These are the most common forms of skin cancer, and are collectively referred to as non-melanoma skin cancers.

  • These arise within the top layer of the skin and can appear on any sun-exposed area of the body, but are most frequently found on the face, ears, bald scalp, and neck.

  • Basal cell carcinoma frequently appears as a pearly bump, whereas squamous cell carcinoma often looks like a rough, red, scaly area, or an ulcerated bump that bleeds.

  • Although non-melanoma skin cancer spreads slowly, if left untreated, it can lead to disfigurement.

  • Researchers estimate that 5.4 million cases of non-melanoma skin cancer, including basal cell carcinoma and squamous cell carcinoma, were diagnosed in 3.3 million people in the United States in 2012.

  • See a board-certified dermatologist if you spot anything changing, itching, or bleeding on your skin.

  • When caught early and treated properly, skin cancer is highly curable.

Melanoma

To help you spot skin cancer early, when its most treatable, the American Academy of Dermatology recommends that everyone learn the ABCDEs of melanoma:

Basal Cell And Squamous Cell Survival Rates

Because basal cell and squamous cell carcinomas are lower-risk skin cancers, theres little information on survival rates based on stage.

Both types of cancer have a very high cure rate. According to the Canadian Cancer Society, the five-year survival rate for basal cell carcinoma is 100 percent. The five-year survival rate for squamous cell carcinoma is 95 percent.

Merkel Cell Carcinoma: A Rare Skin Cancer On The Rise

Merkel cell carcinoma is a rare type of skin cancer that affects about 2,000 people in the United States each year.

Though its an uncommon skin cancer, cases of Merkel cell carcinoma have increased rapidly in the last couple of decades.

This type of cancer starts when cells in the skin, called Merkel cells, start to grow out of control.

Merkel cell carcinomas typically grow quickly and can be difficult to treat if they spread.

They can start anywhere on the body, but Merkel cell carcinomas commonly affect areas exposed to the sun, such as the face, neck, and arms.

They may look like pink, red, or purple lumps that are firm when you touch them. Sometimes, they can open up as ulcers or sores.

How Fast Melanoma Spreads

Types of Skin Cancer

Some forms of melanoma can spread quickly, though the exact timeline will depend on your individual health situation. The timeline can be impacted by factors like your age, family history, any underlying medical conditions you may have, as well as what kind of melanoma you have.

During the diagnosis process, your dermatologist will determine what stage your cancer is at. The stage of your melanoma indicates what kind of treatment youll need.

Melanoma can spread quickly and be difficult to treat at later stages, so its important to seek treatment immediately after diagnosis, even if youre only at Stage 0 or Stage 1.

After Squamous Cell Cancer Of The Skin Has Been Diagnosed Tests Are Done To Find Out If Cancer Cells Have Spread Within The Skin Or To Other Parts Of The Body

The process used to find out if cancer has spread within the skin or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment for squamous cell carcinoma of the skin.

Basal cell carcinoma of the skin rarely spreads to other parts of the body. Staging tests to check whether basal cell carcinoma of the skin has spread are usually not needed.

The following tests and procedures may be used in the staging process for squamous cell carcinoma of the skin:
