Have you ever felt something like a lump that is growing and getting bigger somewhere on your body? Sometimes, for no apparent reason, you may experience swelling or numbness in an arm or leg. Although we usually don't pay much attention to these things, there may be something serious hidden behind them. Today, we are going to talk about a special type of cancer that many people don't hear about often, but it is very important for all of us to be aware of. Don't be afraid, let's understand this simply.
What is ``Undifferentiated Pleomorphic Sarcoma - UPS''?
Simply put, ``Undifferentiated Pleomorphic Sarcoma'' or ``UPS'' as we call it for short, is a type of cancer called soft tissue sarcoma . This is when cancer cells form in the soft tissues of our body, such as muscles, fatty tissue, and blood vessels.
Most often, this `(UPS)` starts in the soft tissues of your arms or legs . Sometimes it can also occur in the deep part of the back of the abdomen, called the `retroperitoneum` . Very rarely, this `(UPS)` affects the bones. The sad thing is, this is usually a fairly aggressive type of cancer . So it is more likely to spread to other parts of the body, especially the lungs or lymph nodes .
In the past, this `(UPS)` was called `malignant fibrous histiocytoma` . The reason for this is that researchers thought that this cancer arises from special immune cells called `histiocytes` . However, later research found that it most likely begins in cells called `mesenchymal cells`, which make up the connective tissue in our body.
Now let's look at the meaning of the two words in this name.
"Undifferentiated" means that these cancer cells take on a very chaotic, disorganized appearance . Like toys scattered around without any order. They have become so different and immature that it is impossible to know exactly which healthy cells they started from or what function they were intended to perform.
The word "pleomorphic" means that these cells are different in shape, size, or the nucleus, the control center of the cell . Think of it like a piece of furniture that is not made from the same mold, each one is different in shape and size. Some cells are small, some are large. Some are round, some are elongated. Even the nucleus, which contains the chromosomes inside the cells, is different in each cell. This is why these cancer cells grow very irregularly and rapidly without any control.
UPS is actually a very rare type of cancer . For example, less than 5,000 people in the United States are diagnosed with the disease each year. However, among the types of soft tissue sarcomas, UPS is the third most common type of soft tissue sarcoma , after liposarcoma (a cancer that develops in fatty tissue) and leiomyosarcoma (a cancer that develops in smooth muscle).
What are the symptoms of `(UPS)`?
The symptoms of `Undifferentiated Pleomorphic Sarcoma (UPS)` can vary from person to person. Some people may not experience any symptoms. However, there are some common symptoms:
- A gradually growing lump or mass: This is the main symptom. It can feel like a lump anywhere on the body, especially in an arm, leg, or abdomen.
- A painless lump that may or may not move when touched: Most of the time, these lumps do not cause pain in the early stages. Therefore, some people may not pay much attention to them.
- Numbness or burning sensation due to the tumor pressing on a nerve: Sometimes, as this tumor grows, it can press on a nearby nerve. This can cause numbness in the hands or feet, a tingling sensation, or a burning sensation.
- Swelling in an arm or leg: If an arm or leg swells for no apparent reason, that should also be taken into consideration.
Importantly, UPS does not always show obvious symptoms. They are often painless , and there is no change in the skin over the lump (such as discoloration or sores). Also, common symptoms such as fever, weight loss, and malaise are not commonly seen.
What are the causes of `(UPS)`?
Experts still don't know exactly what causes UPS. What they do know is that it is caused by changes (mutations) in the DNA (the molecule that contains our genetic information) of healthy cells. However, what causes those changes in DNA is not yet clear.
Risk Factors That Increase the Risk of Developing UPS
A risk factor is something that increases the likelihood of developing a disease. There are several risk factors that have been identified for `(UPS)`. But remember, not everyone who has these risk factors will develop `(UPS)`, and it cannot be said that people who do not have any of these risk factors will not develop `(UPS)`.
The currently identified risk factors are:
- Being male: Men are more likely to develop this disease than women, with the risk being particularly high among white men.
- Over 50 years of age: The incidence of this disease increases with age.
- Certain medical conditions: For example, people with diseases such as neurofibromatosis (a condition that causes tumors to form in the nervous system) or Paget's disease of bone (a disease that causes abnormal bone growth) are at increased risk of developing (UPS).
- Certain genetic conditions: People with rare genetic conditions like Li-Fraumeni syndrome are at increased risk of developing various types of cancer, including (UPS).
- Exposure to certain chemicals: Long-term exposure to certain chemicals, such as arsenic or vinyl chloride, can also be a risk factor.
- Previous radiation therapy to the affected area: If you have received radiation therapy to an area for another disease, there is a small risk of developing sarcoma (UPS) in that area later.
- Occupational exposure to radiation: If you have to be exposed to radiation in some jobs, that can also be a risk factor.
It's amazing that many people who develop UPS don't have any of these risk factors . So if you see something that looks like an unusual lump on your body, don't ignore it by thinking, "I don't have any of these risk factors."
How do doctors identify `(UPS)`?
When you see a doctor with a lump like this, he will first ask you about your health, whether anyone in your family has had diseases like cancer (family history), etc. Then he will ask about your symptoms. How long has this lump been there? Is it getting bigger? Is it painful? In addition, he will do the following tests:
1. Physical exam: The doctor will examine the location of the tumor, its size, and how it feels when touched (hard or soft).
2. Imaging tests: These tests help to see what the tumor looks like inside and how far it has spread. Usually, one or more tests, such as X-rays, ultrasound scans, and/or MRI scans, may be done.
3. Biopsy: This is the most important test to definitively diagnose the disease . This involves taking a small piece of tissue from the tumor (perhaps with a small needle-like instrument) and having it examined under a microscope by a pathologist (a doctor who specializes in diagnosing diseases). Only then can we say for sure whether it is UPS or another condition.
What are the treatments for `(UPS)`?
Treatment for UPS depends on factors such as the size of the tumor and whether the cancer has spread. The main treatment for early-stage UPS is surgery to remove the tumor . This is often done in combination with radiation therapy . However, sometimes additional cancer treatments may be needed.
Surgery
The main goal of surgery for `(UPS)` is to completely remove the cancer . Doctors try to remove not only the cancer, but also a small amount of healthy tissue around it (this is called the "margin") . Just like when we remove a weed in a garden, we remove not only the plant, but also a small layer of soil around it. Then not even a small piece of the root of the weed is left. In the same way, when doctors remove this cancer, they remove it along with a small amount of healthy tissue around it. Only then can we be sure that all the cancer cells are removed without any remaining. If there are cancer cells at the edge of the removed tumor, it means that there may be more cancer cells left in the body.
If the tumor is in your arm or leg, your surgeon will try to remove the cancer and preserve as much function as possible in that arm or leg. However, in some severe cases, amputation may be necessary . Therefore, it is important to talk to your oncologist to decide which treatment option is best for your situation.
Additional Cancer Treatments
Oncologists may also use additional treatments before or after surgery. Although these treatments often do not shrink the tumor, they can help to make it safe for surgery to remove the tumor, or to kill any cancer cells that may remain after surgery.
These additional treatments are:
- Chemotherapy: Giving drugs that kill cancer cells.
- Immunotherapy: Stimulating the body's own immune system to fight cancer cells.
- Radiation therapy: The use of high-energy rays to destroy cancer cells.
Your treatment plan is unique to you. It may be different from someone else's. So talk to your oncologist about your options. You will often be treated by a multidisciplinary team . This team may include a surgeon, a radiation oncologist, and a medical oncologist. Although each specialist has a different role, they all work together to treat you. They will help you decide what is best for your situation.
When should I see a doctor?
If you notice a lump or growth anywhere on your body that is slowly growing , especially if it is accompanied by symptoms such as pain, swelling, or inability to move your limb properly , you should see a doctor immediately .
If you have already been diagnosed with (UPS), tell your oncologist right away if you develop new symptoms, or if your symptoms get worse .
What kind of things can someone with `(UPS)` expect?
Life expectancy varies from person to person. It depends on the size of the sarcoma and the stage of the disease . In general, the five-year survival rate for high-grade (UPS) is about 60% . This means that about 60% of people diagnosed with the disease are still alive after five years. The 10-year survival rate is about 48% .
But remember, these survival rates are just general estimates . They don't tell you exactly how long you'll live or what treatment will be most effective for you. To learn more about survival rates and how they affect you, it's best to talk to your oncology team.
Can `(UPS)` be completely cured?
(UPS) is completely curable, especially if diagnosed early . Even in cases where the disease has spread, there are treatment options that can help improve your quality of life and prolong your life. As with any type of cancer, early detection and treatment of (UPS) is the best way to achieve a successful outcome .
Things to consider
When you are diagnosed with cancer, it can affect every aspect of your life. If it is a rare cancer like Undifferentiated Pleomorphic Sarcoma (UPS), you may feel very alone and like no one understands you. At times like these, it can be helpful to join a support group where there are others who are going through the same experiences as you . Talking to them can help you understand your feelings and manage them.
Also, your medical team is always there to help you . They can talk to you about your treatment options, support you, and provide you with the information and resources you need to make informed health decisions. Don't be afraid to ask them any questions you have . Always remember that you are not alone.
