Understanding Rare Cancers

Four facts to know about one type of rare cancer, soft tissue sarcomas

(Family Features) Although rare cancers don’t occur often, they can affect people of all ages and genders.

A rare cancer is defined as fewer than 15 new diagnoses per 100,000 people per year, according to the National Cancer Institute (NCI). Additionally, as noted by the American Cancer Society (ACS), the 5-year survival rate is lower for people diagnosed with a rare cancer than for people living with more common cancers. Greater awareness of rare cancers may lead to earlier diagnosis and management, and potentially better survival rates.  

1. There are more than 50 types of soft tissue sarcomas (STS). STS account for about 1% of all cancers and affect soft tissues such as muscle, fat, nerves, blood vessels and skin. Although STS can be found in any part of the body, they are often in the arms or legs, internal organs, the back of the abdominal cavity or in the trunk, head and neck area.

If you have recently been diagnosed with STS, it’s important to ask your doctor for more information about the specific sub-type you have. For example, if you received a diagnosis of undifferentiated sarcoma, ask your doctor for an integrase interactor-1 (INI1) test to see if you have a rare STS called epithelioid sarcoma (ES). (See sidebar for more on ES.)

2. STS can be visible or invisible depending on location. STS may appear as painless bumps under the skin, usually on arms or legs. Some sarcomas begin in the abdomen and typically don’t show symptoms until they grow and press on nearby organs, nerves, muscles or blood vessels. When this occurs, symptoms may include pain and trouble breathing.

3. Early diagnosis can help inform disease management. As with other types of cancer, early diagnosis of STS is key, as earlier treatment may result in more favorable outcomes. Because other conditions can cause similar symptoms, it’s important to check with your doctor if you are experiencing any of the warning signs listed above. If your doctor decides it’s best to “watch and wait,” consider developing a six-week follow-up plan in partnership with your health care team if your symptoms have not improved.

4. Seeking care from a specialist is key. Given the rarity of STS, finding a sarcoma specialist who understands the complexity of this rare disease and can help determine which treatment option is best for you is important. Treatment options depend on multiple factors, including your overall health, the location and type of tumor, its size and whether the disease has spread elsewhere in the body. STS are typically treated with a combination of options including chemotherapy, radiation therapy and surgery. A specialist may also speak to you about participating in a clinical trial where investigational therapies in STS are being studied.

Learning More About Epithelioid Sarcoma

A rare type of STS, epithelioid sarcoma (ES) accounts for less than 1% of all STS, which themselves account for approximately 1% of all cancers, according to research published in “Archives of Pathology & Laboratory Medicine.” ES can present as a lump or sore on the skin.

Notably, more than 90% of ES tumors do not express the INI1 protein, which when present acts to suppress tumor growth. INI1 loss plays an important role in the diagnosis of ES, according to researchers with “The American Journal of Surgical Pathology.”

Data from the NCI indicates that approximately 150-200 people in the United States are diagnosed with ES each year. Research published in “The Journal of Clinical and Aesthetic Dermatology” found the disease often occurs in young adults in their 20s and 30s. Because most ES patients are adolescents and young adults, there is a gap in the unique psycho-social needs for this patient population, including resources for patients who miss school while undergoing treatments, as well as fertility considerations later in life.

If you or someone you love is living with ES, you can find resources, information and the real-life perspective of an ES survivor at ESsentialsforES.com.

The Rarest of the Rare

What to know about a cancer you may not have heard of

(Family Features) A woman celebrating her 40th birthday, a young boy starting second grade or a college grad about to begin his career. All three could develop a rare form of cancer known as epithelioid sarcoma (ES), a form of soft-tissue sarcoma.

There is little information available about ES. Patients, advocates, doctors and researchers across the United States are aiming to educate people about this ultra-rare cancer and the unmet need for an effective, tumor-specific treatment. Consider these facts about ES:

What are Soft-Tissue Sarcomas and What is Epithelioid Sarcoma?
Soft-tissue sarcomas (STS) are a type of cancer that occur in tissue like muscle, fat, skin, nerves and blood vessels. There are more than 50 types of STS, including ES, which is a rare form that can occur under the skin in the limbs (such as the arms, hands, legs or feet) or soft tissue in other places like the abdomen. Adults in their 20s and 30s and men, in particular, are more likely to get ES, although it can affect people of all ages and genders, according to research published in the Journal of Clinical and Aesthetic Dermatology.

How Rare is Rare?

According to the American Cancer Society, a rare cancer is defined as fewer than six new diagnoses per 100,000 people per year.

ES is an ultra-rare cancer. According to available epidemiology and case reports, it is estimated about 600 people are properly diagnosed in the U.S. and Europe each year.

What are the Most Common Types of ES and How Do They Impact Diagnosis?
ES can take two forms:
Distal-type: Classic form, typically affects teenagers and young adults.

• Typically forms under the skin in areas like hands, legs and feet.
• Can be mistaken for another skin condition like an infected wart or a wound that won’t heal, which may delay diagnosis.
• Proximal-type: Rarer form, mainly affects adults and is more aggressive.
• Typically forms in central areas of the body like the abdomen.
• Can be mistaken for menstrual cramps or an upset stomach, making identification and diagnosis more difficult.

Dealing with a Diagnosis?
Due to its rarity, harmless appearance in its initial stages and occurrence in young people, ES is often misdiagnosed, according to the Liddy Shriver Sarcoma Initiative. For this reason, the Sarcoma Foundation of America recommends checking often for lumps and bumps in places they shouldn’t be.

For people faced with a sarcoma diagnosis, it’s important to get a second opinion from a sarcoma specialist. These specialists have extensive knowledge of STS and can determine what form of sarcoma one may have, what stage it is and the best course of treatment. The specialist may confirm the diagnosis with a physical examination, a scan or a tissue sample (biopsy) of the area.

It’s common to feel a range of emotions after a diagnosis of ES, according to Clear View Health Partners, including:

• Fear
• Denial
• Frustration
• Anxiety
• Hope that treatment will be successful
• Determination to beat ES

What Treatment Options are Available?
Treatment options depend on a variety of factors, including the location of the tumor, tumor staging and whether the disease has metastasized or spread to other parts of the body.

For patients with early stage ES, many elect to have surgery to remove the tumor, which may precede or be followed by radiation therapy or chemotherapy treatment, according to the Journal of Clinical and Aesthetic Dermatology. If the cancer returns or spreads, a patient may undergo radiation therapy and chemotherapy. New treatment options are being studied through clinical research, which is why seeking a specialist in the field is important if one is faced with a diagnosis.

As with many cancers, early detection is important and can increase survival or successful treatment. Typically, the distal form of ES is associated with more favorable survival rates than the proximal form.

An ES Diagnosis Journey

In the spring of 2008, Maria Voermans’ 4-year-old daughter requested an “airplane ride,” and as Voermans lifted the young girl up with her legs, she had to make an “emergency landing” because of some sudden and significant pain in her upper right thigh.

After a few months, the pain persisted. Voermans continued to jog and play sand volleyball, thinking nothing of it. At the recommendation of her primary care physician, she took some anti-inflammatories and tried to rest, which wasn’t easy to do as a single mother of two young children.

Two more months went by and her leg caused increasing problems. She could feel something in her leg, but never considered it a “lump” because it was not visible on the outside. Voermans took matters into her own hands and visited a sports medicine orthopedic specialist for further testing.

An MRI found a mass in her right leg and she was referred to one of the few musculoskeletal oncologists in Wisconsin, her home state. He ordered a biopsy, which on Voermans’ youngest daughter’s third birthday confirmed her worst fear: it was a rare form of cancer called proximal-type epithelioid sarcoma, and it was stage three. Her biggest concern was not living to experience future holidays, birthdays, graduations and other life milestones with her daughters.

Voermans underwent chemotherapy, radiation therapy and had surgery to remove the tumor. As of July 2018, Voermans reports the cancer has not returned.

Today, she’s a wellness coordinator supporting other people diagnosed with cancer who are undergoing treatment or post-treatment. She’s able to use her own cancer journey to provide empathy to others, and it’s brought satisfaction to the whole experience.
