How Do They Treat Squamous Cell Carcinoma

There Are Three Ways That Cancer Spreads In The Body

Cancer can spread through tissue, the lymph system, and the blood:

• Tissue. The cancer spreads from where it began by growing into nearby areas.
• Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
• Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

What Are The Treatments For Squamous Cell Carcinoma

Your doctor will help you to decide on the best type of treatment. Factors in the decision include your overall health and age, the location of the cancer, and how invasive the cancer is.

Treatment options include:

• Scratching off with a curette, an instrument that may end in a ring or a spoon, and then burning with a special electric needle. This method is called electrodessication and curettage.
• Surgical removal:
• Mohs surgery: This is a specialized technique. The doctor first removes the visible cancer and then begins cutting around the edges. The tissues are examined during the surgery until no more cancer cells are found in tissues around the wound. If necessary, a skin graft or flap might be applied to help the wound heal.
• Excisional surgery: The growth and a bit of surrounding skin is removed with a scalpel.

If you have some type of advanced or very invasive SCC, you might find that it returns or metastasizes . There are several medications which have been approved to treat locally advanced cancers that cannot be simply treated or those that have spread to other areas of the body.

More On Clinical Trials In Squamous Cell Skin Cancer

Clinical trials are research studies that test how well new medical approaches work. They have an important place in your care as researchers strive to improve current cancer treatments and search for new and better ones. Clinical trials are essential for learning about cancer and how to prevent or cure it.

Our most-effective cancer treatments would not be available without the clinical trial process. Unfortunately, many people with cancer are unaware of the option for a clinical trial or are unsure about the value of participation.

Your goal is to find the best treatment available whenever you make a treatment decision. While there may be a good standard of care for youcare that experts believe is appropriate for your specific diagnosis and treatment historysometimes the current standard of care is not as effective as you and your healthcare team would like. Other times, the standard of care works for a time but then stops working. In still other instances, there is no standard of care for your situation. At these times, participation in a clinical trial may be the best option for you.

The best time to search for clinical trials is every time you are faced with a treatment decision.

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.

What Survival Rates Mean

The survival rate is the percentage of people who live for a certain period of time with this cancer. The number is based on research done on large groups of people with the same stage of cancer.

Experts dont know the exact survival numbers for late-stage SCC, because cancer registries dont track statistics for this cancer. However, your doctor may be able to give you an estimate of your prognosis.

When it comes to surviving cancer, everyone is different. Your outcome will depend on the specific treatments you have and how well you respond to them. Talk to your doctor about your outlook and what it means.

What Is Aggressive Squamous Cell Carcinoma

Aggressive SCC or high-risk SCC is cancer that is more likely to recur or metastasize . Features of high-risk SCC are:4,9

• Larger than 2 centimeters
• Deeper than 2 millimeters
• Near the lip and ear
• Located in a scar or other injured skin
• Spread into a nerve
• Poorly differentiated

Having a weakened immune system due to medications or infections increases the risk of aggressive SCC. History of radiation exposure or use of psoralen UVA treatment are other risk factors for aggressive SCC.9

What Are The Symptoms Of Squamous Cell Skin Cancer

Squamous cell cancers are usually raised growths, ranging from the size of a pea to the size of a chestnut. They may appear as scaly red patches, open sores or protruding growths with a dented center, or they may look like a wart. Most are found in areas of the body that are frequently exposed to the sun, such as the ears, lips, face, balding scalp, neck, hands, arms, and legs. Less commonly, they may appear on mucous membranes and genitals. Regardless of what form the bumps take, they do not heal or go away on their own.

How Chipsa Treats Squamous Cell Carcinoma Patients

Learn how CHIPSA treats patients with squamous cell carcinoma, the second most common form of skin cancer.

What is squamous cell carcinoma?

Squamous cell carcinoma is the second most common form of skin cancer after basal cell carcinoma. It begins in the thin, flat cells that make up the outermost layer of the skin. Although the cancer is slow growing, if left untreated, it can spread to other parts of the body and become life-threatening.

SCC usually shows up in red, scaly patches, open sores, or warts on the skin. They most often appear in areas that are exposed to the ultraviolet rays, such as the face, hands, and ears. It can also show up in the mouth, anal area, or genitals. As the SCC grows, it may look like a raised bump that crusts or bleeds.

Risk factors for developing SCC include being fair-skinned, having light hair and blue, green, or gray eyes, having had long-term exposure to UV radiation, and having a history of multiple severe sunburns.

The earlier SCC is detected, the better. Once it has spread to lymph nodes or other organs, the disease becomes much more serious.

CHIPSAs Squamous Cell Carcinoma Success Stories

CHIPSA has treated several SCC patients, most of whom came in at the late stages when the cancer had already spread.

Johns SCC Story

So John began to research hospitals outside of the U.S., and thats when he discovered CHIPSA. He was pleased to find a place who was willing to listen to his ideas and be open to other treatment options.

Squamous Cell Carcinoma Treatment

Squamous cell carcinoma can usually be treated with minor surgery that can be done in a doctors office or hospital clinic. Depending on the size and location of the SCC, your doctor may choose different techniques to remove it.

For small skin cancers:

• Curettage and electrodessication : removing the top layer of the skin cancer then using an electronic needle to kill cancer cells
• Laser therapy: an intense light destroys the growth
• : a photosensitizing solution applied to your skin then activated with a light or daylight, or sometimes with intense pulsed light
• Cryosurgery: freezing of the spot using liquid nitrogen

For larger skin cancers:

• Excision: cutting out the cancer spot and some healthy skin around it, then stitching up the wound
• Mohs surgery: excision and then inspecting the excised skin using a microscope this requires stitching up the wound

What Are The Different Types Of Skin Cancer

Your skin has multiple layers. The outer, protective layer of the skin is known as the epidermis. The epidermis is made up of squamous cells, basal cells, and melanocytes. These cells are constantly shedding to make way for fresh, new skin cells.

However, when certain genetic changes occur in the DNA of any of these cells, skin cancer can occur. The main types of skin cancer are squamous cell carcinoma, basal cell carcinoma, and malignant melanoma.

Prevention Of Squamous Cell Carcinoma

People whose squamous cell carcinomas have returned or are large should be treated with a technique called Mohs microscopically controlled surgery Mohs Microscopically Controlled Surgery Basal cell carcinoma, the most common skin cancer, originates in certain cells of the outer layer of the skin . Usually, a small, shiny bump appears on the skin and enlarges slowly… read more . Radiation therapy may be done after surgery.

Squamous cell carcinoma that has spread to only one or a few other parts of the body is treated with radiation therapy. If the cancer is widespread, radiation therapy may not be used, and chemotherapy is usually not effective.

People who cannot have surgery and who have large squamous cell carcinomas that have spread to underlying tissue or elsewhere in the body may be given PD-1 inhibitors . PD-1 inhibitors help the body’s immune system destroy the cancer. These drugs are called PD-1 inhibitors because they block the action of a protein on the surface of the cancer cell called programmed cell death protein 1. This protein protects the cancer cell from the effects of the immune system. When PD-1 inhibitors block the protein, the immune system is able to attack the cancer cell and kill it.

Because there is a greater risk of metastasis than with basal cell carcinoma, doctors closely monitor treatment and follow-up.

Treating Squamous Cell Carcinoma

Most of squamous cell carcinomas can be cured if they are treated early. Once squamous cell carcinoma has spread beyond the skin, though, less than half of people live five years, even with aggressive treatment.

There are many ways to treat squamous cell carcinoma that has not spread. These include:

• cutting away the cancer and a small amount of healthy tissue around it. If a large area of skin is removed, a skin graft may be necessary.
• scraping away the cancer with a surgical tool. An electric probe is used to kill any cancerous cells left behind.
• freezing cancer cells with liquid nitrogen. This treatment is usually used only for very small tumors or for a patch of skin that looks abnormal but isn’t yet cancerous.
• destroying the tumor with radiation.
• shaving away the cancer, one thin layer at a time. Each layer is examined under the microscope as it is removed. This technique helps the doctor preserve as much healthy skin as possible.
• applying drugs directly to the skin or injecting them into the tumor
• using a narrow laser beam to destroy the cancer.

The treatment that is best for you depends on the size and location of the cancer, whether it has returned after previous treatment, your age, and your general health.

Once your treatment is finished, it’s important to have regular follow-up skin exams. Your doctor may want to see you every three months for the first year, for example, and then less often after that.

Basal Cell And Squamous Cell Carcinomasigns And Symptoms

The most common warning sign of skin cancer is a change on the skin, especially a new growth or a sore that doesnt heal. The cancer may start as a small, smooth, shiny, pale or waxy lump. It also may appear as a firm red lump. Sometimes, the lump bleeds or develops a crust.

Both basal and squamous cell cancers are found mainly on areas of the skin that are exposed to the sun the head, face, neck, hands and arms. But skin cancer can occur anywhere.

An early warning sign of skin cancer is the development of an actinic keratosis, a precancerous skin lesion caused by chronic sun exposure. These lesions are typically pink or red in color and rough or scaly to the touch. They occur on sun-exposed areas of the skin such as the face, scalp, ears, backs of hands or forearms.

Actinic keratoses may start as small, red, flat spots but grow larger and become scaly or thick, if untreated. Sometimes theyre easier to feel than to see. There may be multiple lesions next to each other.

Early treatment of actinic keratoses may prevent them from developing into cancer. These precancerous lesions affect more than 10 million Americans. People with one actinic keratosis usually develop more. Up to 1 percent of these lesions can develop into a squamous cell cancer.

Basal cell carcinoma is the most commonly diagnosed skin cancer. In recent years, there has been an upturn in the diagnoses among young women and the rise is blamed on sunbathing and tanning salons.

Nonsurgical Options For Treating Cscc

Various nonsurgical treatments are available for CSCC depending on the extent of your cancer and where it is in your body.

During PDT, your doctor will apply a light-sensitizing liquid drug to your skin. Then a special type of light is used to destroy cancer cells.

After having this treatment, you must avoid sunlight for at least 48 hours.

PDT is used for some minor CSCCs and a precancerous condition called actinic keratosis .

Radiation Therapy

Radiation therapy involves using beams of energy to kill cancer cells. Your doctor might recommend radiation if you cant have surgery or if youve had surgery for CSCC but have a high risk for recurrence.

There are different types of radiation used to treat CSCC, including:

• Superficial Radiation With this type, beams of radiation are directed right under the skin, so it treats only the tumor.
• External Beam Radiation External beam radiation sends high-energy beams into the tumor to kill cancer cells.
• Brachytherapy Radioactive implants are placed in or near the cancerous lesion.

Cryosurgery

Cryosurgery is a technique where doctors use liquid nitrogen to freeze and destroy skin cancer lesions. Eventually, the growth falls off and healthy skin emerges.

This method is typically used for superficial CSCCs or in patients who have bleeding disorders, implantable heart devices, or problems tolerating anesthesia.

Topical Treatments

Some creams and gels that can treat low-risk or precancerous CSCCs include:

What Is The Difference Between Actinic Keratosis And Squamous Cell Carcinoma

Actinic keratosis is a benign lesion, though it is considered premalignant. It is the precursor of squamous cell skin cancer. Once it grows, it has a 6-10% chance of turning into a full-blown tumor after 10 years. However, up to 25% of cases go away on their own within a year of minimizing UV exposure. That should give you plenty of time to keep it from becoming cancerous.

Actinic keratoses are scaly, reddish, firm, raised skin patches with poorly defined borders. They may resemble other skin blemishes, but you can tell them apart by their sandpaper-like roughness. They can occur singly or in multiples in sun-exposed locations and are typically accompanied by other signs of UV damage.

Tumors resulting from sun exposure are usually slow-growing. Meanwhile, highly aggressive types are frequently associated with other risk factors, such as a personal history of cancer and receiving chemotherapy, immunosuppression, chronic skin trauma, etc.

Sudden Bleeding And Scabbing

Two days before surgery, I looked in the mirror in the morning and I noticed dried blood on my face. I had a few places on my face that had been bleeding and scabbing which my doctor was going to remove, but this was on the tip of my nose. And the day before, I had nothing on the tip of my nose. While this was bothersome, I planned on mentioning it to my doctor on the day of surgery.

Signs And Symptoms Of Squamous Cell Carcinoma

It is important to see your dermatologist whenever you notice a change in a mole or area of your skin. Squamous cell carcinoma symptoms include:

• A sore that wont heal, or that heals and then regrows
• An elevated growth on the skin that feels rough
• A reddish, scaly patch that grows slowly

If you have a sore or scab for more than two months without healing, or a flat patch of scaly skin that wont go away, make an appointment to see your dermatologist.

What Is The Treatment For Advanced Or Metastatic Squamous Cell Carcinoma

Locally advanced primary, recurrent or metastatic SCC requires multidisciplinary consultation. Often a combination of treatments is used.

• Experimental targeted therapy using epidermal growth factor receptor inhibitors

Many thousands of New Zealanders are treated for cutaneous SCC each year, and more than 100 die from their disease.

What Causes Squamous Cell Carcinoma

Repeated exposure to ultraviolet light, either from the sun or from tanning beds, is the main cause of SCC. Indoor tanning is linked to about 168,000 cases of SCC in the US each year.

People with light skin, light hair , and light eyes have a higher risk of skin cancer in general, as well as SCCs. However, most of the skin cancers that develop in African Americans are SCCs.

Other risk factors include:

• Having an impaired immune system, including:
• Cancers of the blood or bone marrow.
• Chronic infections like HIV.
• Taking immunosuppressive medications, including chemotherapy or some biologic medications.
