Is Melanoma Skin Cancer Curable

A Dangerous Skin Cancer

How Dangerous is Melanoma? Is it Treatable?

Melanoma is a serious form of skin cancer that begins in cells known as melanocytes. While it is less common than basal cell carcinoma and squamous cell carcinoma , melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage.

Learn more about melanoma types, risk factors, causes, warning signs and treatment.

Melanoma Fact

Only 20-30% of melanomas are found in existing moles.

While 70-80% arise on normal-looking skin.

What Are The Signs Of Symptoms Of Metastatic Melanoma

Signs and symptoms depend upon the site of metastasis and the amount of tumor there. Metastases to the brain may first appear as headaches, unusual numbness in the arms and legs, or seizures. Spread to the liver may be first identified by abnormal blood tests of liver function long before the patient has jaundice, a swollen liver, or any other signs of liver failure. Spread to the kidneys may cause pain and blood in the urine. Spread to the lungs may cause shortness of breath, other trouble breathing, chest pain, and continued cough. Spread to bones may cause bone pain or broken bones called pathologic fractures. A very high tumor burden may lead to fatigue, weight loss, weakness and, in rare cases, the release of so much melanin into the circulation that the patient may develop brown or black urine and have their skin turn a diffuse slate-gray color. The appearance of multiple blue-gray nodules in the skin of a melanoma patient may indicate widespread melanoma metastases to remote skin sites.

New Types Of Treatment Are Being Tested In Clinical Trials

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.

Vaccine therapy

Vaccine therapy is a cancer treatment that uses a substance or group of substances to stimulate the immune system to find the tumor and kill it. Vaccine therapy is being studied in the treatment of stage III melanoma that can be removed by surgery.

Many Melanomas Dont Require Immediate Treatment

Many people have this concept that all melanomas are extremely rapidly growing cancers, says Dr. Marghoob. They think that waiting even one day after the diagnosis of melanoma can be fatal.

While some subtypes of melanoma do grow extremely fast, says Dr. Marghoob, most early melanomas dont require immediate treatment, allowing ample time to detect, treat, and cure them. Dr. Marghoob advises checking your skin on a monthly basis. If you notice a changing spot on your skin, dont delay in getting it checked out by a dermatologist, he says. And if your doctor does think you may have a melanoma, know that for most people its not necessary to rush to treatment. Most people can take the time they need to meet with doctors and understand their options.

What Is A Melanoma

Melanoma involves the uncontrolled growth of a type of cell known as a melanocyte. One of the most important functions of a normal melanocyte is to protect your skin from the suns damaging ultraviolet rays. It does this by producing melanin pigment.

There are many factors that may result in the development of melanomas. These include environmental factors such as sun damage or use of tanning beds; immune suppression; genetic causes, such as inheritance of a gene that makes you more susceptible to melanomas; and spontaneous gene mutations.

How Effective Is Immunotherapy

Success rates for any cancer treatment, including immunotherapy, depend on individual factors, including the cancer type and stage. In general, immunotherapy is effective against many cancers. While some cancers are more immunogenic than others, in general, immunotherapy is effective across a wide variety of cancers. Immunotherapy can produce durable responses unlike chemotherapy or radiation, however, these occur only in around 25% patients.

Some research suggests that the immune system may remember cancer cells after immunotherapy ends.

Treatment Options: The Old And The New

Until several years ago, treatment options for people with advanced metastatic disease were quite limited. Surgical removal of the cancer, chemotherapy, and less targeted immunotherapy and interferon therapy were possible treatment options. But only about one in 10 patients with advanced metastatic disease survived for five years, and median survival was less than one year.

Thanks to significant developments in genetic research, including findings from the Human Genome Project, patients with widespread disease now have a much better chance of survival. For example, research showing that some melanomas have mutations that abnormally activate certain signaling pathways, which contribute to uncontrolled tumor growth, has led to advances in targeted immunotherapy.

Newer therapies targeting these pathways, and immune checkpoint inhibitors that block specific targets in tumor production pathways, are now available to treat advanced melanoma. These include kinase inhibitors such as dabrafenib and vemurafenib , and immune checkpoint inhibitors such as nivolumab , pembrolizumab , and ipilimumab .

A study examining one of these newer therapies showed that at three years after treatment, the survival rate for people who were treated with the checkpoint inhibitor ipilimumab along with the older chemotherapy drug dacarbazine was 21%, compared to 12% for those who were treated with only dacarbazine.

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.

Not A Cure But An Extension: How Immunotherapy Works For Advanced Lung Cancer

Skin Cancer: Prevention, Warning Signs and Treatment Options

May 3, 2018

For nearly five decades, doctors have usedvarious forms of immunotherapy to treat certain cancers. These treatmentsstimulate the patients own immune system to attack a disease, much like itwould a virus or another foreign invader. Promising data have emerged toindicate its effectiveness against many cancers, including lung, kidney,melanoma, and some colon cancers.

Most recently, lung cancer has receivedattention for data released from a studypublished in The New England Journal ofMedicine and featured in The New York Times. In the study,the immunotherapy drug pembrolizumab was combined with chemotherapyto determine whether the dual approach was more effective than chemotherapyalone for metastatic nonsquamous non-small cell lung cancer.;

The results are encouraging: Patients whoreceived the dual therapy lived longer than those who received onlychemotherapy. In fact, the findings suggest that earlier introduction ofimmunotherapy for certain patients might one day become the standard treatment.

But while the data are promising, we must notbe too eager to declare victory. Todays immunotherapy is not a cure forlate-stage lung cancer. However, it can give certain patients more precioustime with family and friends. To provide that, we must carefully selectpatients who will benefit most and determine the most appropriate availabletreatment.; Recent developments havefocused on immune checkpoint inhibitors and on CAR-T cell therapy.

Squamous Cell Carcinoma Treatment

Squamous cell carcinomas detected at an early stage and removed promptly are almost always curable and cause minimal damage. However, left untreated, they may grow to the point of being very difficult to treat.

A small percentage may even metastasize to distant tissues and organs. Your doctor can help you determine if a particular SCC is at increased risk for metastasis and may need treatment beyond simple excision.

Fortunately, there are several effective ways to treat squamous cell carcinoma. The choice of treatment is based on the type, size, location, and depth of penetration of the tumor, as well as the patients age and general health. Squamous cell carcinoma treatment can almost always be performed on an outpatient basis.

Causes Of Skin Cancer

Australia has one of the highest rates of skin cancer in the world. Anyone can be at risk of developing skin cancer, though the risk increases as you get older.

The majority of skin cancers in Australia are caused by exposure to UV radiation in sunlight.

Some factors that increase your risk of skin cancer include:

  • sunburn

There Are Different Types Of Cancer That Start In The Skin

There are two main forms of skin cancer: melanoma and nonmelanoma.

Melanoma is a rare form of skin cancer. It is more likely to invade nearby tissues and spread to other parts of the body than other types of skin cancer. When melanoma starts in the skin, it is called cutaneous melanoma. Melanoma may also occur in mucous membranes . This PDQ summary is about cutaneous melanoma and melanoma that affects the mucous membranes.

The most common types of skin cancer are basal cell carcinoma and squamous cell carcinoma. They are nonmelanoma skin cancers. Nonmelanoma skin cancers rarely spread to other parts of the body.

How Does Immunotherapy Work

Figure 3 from Treatment of Skin Cancer with a Selective ...

Different types of immunotherapy work differently to fight melanoma. Immunotherapy can be systemic or local.

Systemic;treatments travel through the bloodstream to reach all parts of the body. Cancer physicians use systemic immunotherapy to treat metastatic cancer, which is cancer that has spread from its original location to other areas of the body.

Local;treatments are applied, usually by injection, directly to melanoma lesions. Local immunotherapy treatments work by infecting and killing melanoma cells in the treated lesions. They may also produce an immune response.

Watch Dr. Evan J. Lipson of Johns Hopkins Medicine discuss more on immunotherapy.

What Are Cancer Vaccines

A cancer vaccine can also help your body fight disease. A vaccine exposes your immune system to a foreign protein, called an antigen. This triggers the immune system to recognize and destroy that antigen or related substances. There are 2 types of cancer vaccine: prevention vaccines and treatment vaccines.

In general, immunotherapy is an important approach to find new treatments for cancer. The examples above do not include every type of immunotherapy treatment. Researchers are studying many new drugs. You can learn more about immunotherapy in each cancer-specific section on Cancer.Net; Look at the Types of Treatment and Latest Research pages for specific information about immunotherapy for that type of cancer. You can also learn about the latest immunotherapy research on the Cancer.Net Blog.

Articles On Skin Cancer

Skin cancer — abnormal cell changes in the outer layer of skin — is by far the most common cancer in the world. It can usually be cured, but the disease is a major health concern because it affects so many people. About half of fair-skinned people who live to age 65 will have at least one skin cancer. Most can be prevented by protecting your skin from the sun and ultraviolet rays.

Every malignant skin tumor will, over time, show up on the skin‘s surface. That makes this the only type of cancer that is almost always found in its early, curable stages.

Benign Tumors That Start In Melanocytes

A mole is a benign skin tumor that develops from melanocytes. Almost everyone has some moles. Nearly all moles are harmless, but having some types can raise your risk of melanoma. See Risk Factors for Melanoma Skin Cancer for more information about moles.

A Spitz nevus is a kind of mole that sometimes looks like melanoma. Its more common in children and teens, but it can also be seen in adults. These tumors are typically benign and dont spread. But sometimes doctors have trouble telling Spitz nevi from true melanomas, even when looking at them under a microscope. Therefore, they are often removed, just to be safe.

How Is Skin Cancer Of The Head And Neck Diagnosed

Diagnosis is made by clinical exam and a biopsy. Basal cell and squamous cell cancers are staged by size and extent of growth. Basal cell cancers rarely metastasize to lymph nodes, but they can grow quite large and invade local structures. Squamous cell cancers have a much higher incidence of lymph node involvement in the neck and parotid gland and can spread along nerves.

Melanoma is staged, based not on size but on how deeply it invades the skin layers. Therefore, a superficial or shave biopsy will not provide accurate staging information used to guide treatment. Melanomas can have a very unpredictable course and may spread to distant organs. Melanomas with intermediate thickness often require sentinel node biopsy, a surgical procedure performed by a head and neck surgeon, to determine if microscopic spreading to lymph nodes has occurred.

Where Research Is Headed

A 2017 review of phase III clinical trials found that current targeted therapies and immunotherapy work well to improve overall survival rates in people with advanced-stage melanoma. But the authors say that more research is needed to learn which therapy to try first.

Scientists are developing and testing strategies to identify which patients are most likely to benefit from which treatments. For example, researchers have found that people who have high levels of certain proteins in their blood may respond better than others to checkpoint inhibitors.

Studies are also underway to develop and test new therapies. According to an article in Gland Surgery, early research findings suggest that personalized anti-tumor vaccines may be a safe treatment approach. Scientists are also testing drugs that target melanoma with certain abnormal genes, reports the American Cancer Society.

New combinations of existing treatments might also help improve outcomes for some people with melanoma. Scientists are continuing to study the safety, efficacy, and optimal use of medications that have already been approved to treat this disease.

What If The Skin Changes Are Rapid Or Dramatic

SKIN CANCER A CURABLE DISEASE 2016

Guideline # 4: The more rapid and dramatic the change, the less serious the problem.

When changes such as pain, swelling, or even bleeding come on rapidly, within a day or two, they are likely to be caused by minor trauma, often a kind one doesn’t remember . If a spot changes rapidly and then goes back to the way it was within a couple of weeks, or falls off altogether, it is not likely to represent anything serious. Nevertheless, this would be a good time to say once again: Nobody can diagnose him- or herself. If one sees a spot that looks as though it is new or changing, show it to a doctor. If one see a spot that doesn’t look like one’s other spots, it should be evaluated.

Where Do Skin Cancers Start

Most skin cancers start in the top layer of skin, called the;epidermis. There are 3 main types of cells in this layer:

  • Squamous cells: These are flat cells in the upper part of the epidermis, which are constantly shed as new ones form.
  • Basal cells: These cells are in the lower part of the epidermis, called the basal cell layer. These cells constantly divide to form new cells to replace the squamous cells that wear off the skins surface. As these cells move up in the epidermis, they get flatter, eventually becoming squamous cells.
  • Melanocytes: These are the cells that can become melanoma. They normally make a brown pigment called melanin, which gives the skin its tan or brown color. Melanin protects the deeper layers of the skin from some of the harmful effects of the sun.

The epidermis is separated from the deeper layers of skin by the basement membrane. When a skin cancer becomes more advanced, it generally grows through this barrier and into the deeper layers.

The Future Of Immunotherapy

Terrys story shows the powerful effects, as well as the challenges, associated with immunotherapy. It is a relatively new treatment, and we continue to refine it and use it in new ways. Weve seen how it works against melanoma, as well as kidney cancer and lung cancer.

And while immunotoxicities are not what we want, there is some data to suggest that patients who get them are more likely to respond to the treatment. We dont know exactly why, and through clinical trials we are working to prevent side effects while continuing to reap the benefits of immunotherapy.

Clinical trials offer gold standard of care plus the newest available treatments, often at little to no cost to patients. These studies help us advance treatment options for more patients.

If you or a loved one is diagnosed with metastatic melanoma, ask your doctor about immunotherapy. Find an academic medical center that has teams of experts in place not only to manage your care, but also the potential side effects of treatment.

Weve only scratched the surface of what immunotherapy can offer cancer patients. But at UT Southwestern and Simmons Cancer Center we are determined to continue improving it to help more patients like Terry beat this disease and lead longer, healthier lives.
