Are you experiencing shoulder pain and arm weakness? It could be a Pancoast Tumor!

Do you experience unexplained shoulder pain, sometimes along the side of your neck, along with pain down your arm, numbness in your hand? Sometimes we may think it's just a sprain or a pinched nerve. However, these symptoms can sometimes be a sign of something more serious. That's the condition we're going to talk about today, which is called a Pancoast Tumor.

What is a Pancoast Tumor? Simply put...

Think about it, a Pancoast tumor is a type of lung cancer . But it's a little strange. It forms in the very top of your lungs, right above your first rib. Unlike other lung cancers, a Pancoast tumor doesn't cause a cough or chest pain . Instead, people with this tumor often experience severe shoulder pain and arm weakness . Doctors call this combination of symptoms "Pancoast syndrome." Pancoast syndrome doesn't cause the symptoms of typical lung cancers, so it can take a while to diagnose these tumors. In many cases, a definitive diagnosis isn't made until the cancer has spread to nearby nerves and blood vessels. Pancoast tumors are named after the radiologist who first described them in the early 20th century. Another name for them is superior sulcus tumor.

Are there types of this?

Yes, there are several subtypes of Pancoast tumors. The main ones are:

• Non-small cell lung cancers - for example, adenocarcinomas and squamous cell carcinomas.
• Small cell lung cancers.

The majority of Pancoast tumors are a type of cancer called adenocarcinomas . These cancers start in the lining of your airways and alveoli (the tiny air sacs in your lungs), specifically in the glandular cells that make mucus.

How common is this condition?

Pancoast tumors are very rare , accounting for less than 5% of all lung tumors.

What are the symptoms of this? Let's take a closer look!

Your brachial plexus is affected by a Pancoast tumor.This nerve network can be compressed. This nerve network runs from your upper chest through your neck to your arms. When this pressure is applied, a specific set of symptoms can occur. That's why doctors call it Pancoast syndrome or Pancoast-Tobias syndrome. These symptoms occur on the same side as the tumor . For example, if the tumor is in your right lung, the symptoms will also affect the right side of your body. Symptoms of a Pancoast tumor may include:

• Severe shoulder pain : This may include pain in your shoulder blade.
• Pain radiating down the arm: This pain may stop at the wrist, just above the little finger.
• Weakness in the hand and arm.
• Neck pain.
• Pain in the upper part of the ribs.
• Swelling of the upper arm.
• Loss of dexterity in the hands and fingers.
• Tingling or numbness in the hand.
• Fatigue.
• Chest tightness.
• Weight loss without reason.

About 50% of people with Pancoast tumors also develop a condition called Horner's syndrome , which can cause symptoms such as:

• Facial flushing .
• Drooping eyelid (ptosis).
• Eyelids turning inward (enophthalmos).
• Lack of sweating (anhidrosis).

What causes this? What are the risk factors?

The causes and risk factors for Pancoast tumors are similar to other lung cancers. The main risk factors are:

• Smoking .
• Exposure to secondhand smoke.
• Long-term exposure to certain substances such as asbestos, radon gas, and heavy metals.

Just think, by exposing ourselves to these things, we are unknowingly damaging our lungs. So it is very important to be careful about this.

How does this spread?

Cancer spreads when cancer cells break away from the original tumor, travel through your blood system or lymph system, and form new tumors in other parts of your body. Pancoast tumors can often spread from the upper part of the lungs to the following locations:

• Upper chest.
• Upside down.
• Thoracic ribs.
• The blood vessels closest to the hands.

This spreading of cancer to distant sites is called metastasis .

How is this diagnosed?

In the early stages, Pancoast tumors are not easily visible on a standard two-dimensional chest X-ray. That's why they can be difficult to diagnose. If a doctor suspects a Pancoast tumor based on your symptoms, they may recommend other diagnostic tests, such as:

• Other imaging tests.
• Needle biopsy.
• Video-assisted thoracoscopy surgery (VATS).
• Thoracotomy surgery.

Imaging tests

Advanced imaging technology can help your doctor get a clear picture of your lungs. He or she may order tests like these:

• CT scan (CT - computed tomography scans).
• PET scan (positron emission tomography scans).
• MRI scan (MRI - magnetic resonance imaging).

These types of scans can provide a lot of information, such as the size of the tumor, its location, and whether it has spread to other areas.

Needle biopsy

In a needle biopsy, a doctor takes a sample of fluid, tissue, or cells from an abnormal lump. The sample is then sent to a pathology lab for further testing. Only there can we know for sure if it is cancer and what type it is.

VATS (video-assisted thoracoscopy surgery)

During this procedure, a doctor makes a small incision in your chest and inserts a thoracoscope (a thin tube with a small camera on it). This allows him to look inside your chest cavity and check for tumors or other abnormalities. If any are found, a sample of tissue is taken and sent to a laboratory for testing.

Thoracotomy

In some cases, a doctor may need to perform a thoracotomy. In this, they make an incision on the right or left side of your chest, between the ribs. This allows them to see the affected lung clearly and take a biopsy of any abnormal tissue. In most cases, they will also remove the tumor at the same time. This will save you from having to undergo multiple surgeries.

Let's learn about the staging of this cancer.

Like other types of lung cancer, doctors classify Pancoast tumors using a cancer staging system . They use Roman numerals (I, II, III, IV) and subtypes (A, B) to describe how advanced the tumor is and how far it has spread. For Pancoast tumors, doctors use the letters T, N, M and the numbers 1, 2, 3, 4 to indicate the severity of the condition:

• The letter T refers to the size of your tumor and how far it has spread.
• The letter N refers to whether the cancer has spread to your lymph nodes .
• The letter M indicates whether the cancer has spread to distant parts of the body (metastasis) .

At what stage are Pancoast tumors most often found?

Because Pancoast tumors are difficult to detect in the early stages, most are diagnosed at stage T3 or T4. T3 means the cancer has spread to your chest wall or your sympathetic nerves. T4 means the cancer has spread to other structures, such as your brachial nerves or spinal cord. This is a more serious condition.

What is the treatment?

This depends on where the tumor is and how far the cancer has spread. There are several treatment options:

• Chemoradiation and surgery.
• Chemoimmunotherapy and surgery.
• Chemoradiation and immunotherapy.
• Radiation therapy.
• Targeted treatment.

Chemoradiation and surgery

Surgery is the best treatment whenever possible. However, before surgery, doctors may give you chemoradiation — a combination of chemotherapy and radiation therapy — to shrink the tumor. The surgery to remove a Pancoast tumor can be a bit more complicated. Usually, a surgeon will have to remove your top two ribs. They may also have to remove a major artery and replace it with a vascular graft — an artificial tube that allows blood to flow. Your surgeon will explain all of this to you before the surgery.

Chemoimmunotherapy and surgery

In some cases, doctors may recommend surgery and chemoimmunotherapy.– that is, a combination of chemotherapy and immunotherapy – is used. While chemotherapy kills cancer cells and slows down the growth of the tumor, immunotherapy stimulates your own immune system to help fight the cancer.

Chemoradiation and immunotherapy

Sometimes, surgery is not an option. In such cases, your medical team may recommend a combination of chemoradiation and immunotherapy.

Radiation therapy

If surgery is not possible and the cancer has spread to other parts of the body, your doctor may recommend radiation therapy alone to control the growth of the cancer. This supportive care method can shrink the cancer and relieve your symptoms.

Targeted therapy

Some people benefit from targeted therapy . This treatment targets genetic mutations that cause healthy cells to become cancer cells. To find out if you are a good candidate for targeted therapy, a doctor will test your cancer cells to see if they have specific receptors for specific proteins. If you have questions about this, talk to your doctor.

Can this be prevented?

Although Pancoast tumors cannot be completely prevented, there are things you can do to reduce your risk of developing this type of cancer:

• Avoid smoking and other tobacco products. If you smoke, talk to your doctor for help quitting.
• Avoid exposure to secondhand smoke as much as possible.
• Make sure your environment is free of harmful chemicals like asbestos .

Although these may seem like small things, they can have a big impact on your health in the long run.

Additionally, if someone in your family has a history of lung cancer, or if you have a higher risk of developing lung cancer, it's a good idea to ask your doctor about preventive cancer screenings .

What to expect if you have a Pancoast tumor?

If you are diagnosed with a Pancoast tumor, your doctor will put together a treatment team tailored to your specific needs. Your treatment team may include:

• Thoracic surgeons.
• Neurosurgeons.
• Oncologists , that is, medical oncologists, surgical oncologists, and radiation oncologists.

Your medical team will recommend treatment based on the size of the Pancoast tumor, its location, and whether the cancer has spread to other areas.

How fast do these nuts grow?

Most of the time, Pancoast tumors grow slowly . However, very rarely, a tumor can grow very quickly. Your doctor will monitor the growth of the tumor regularly before, during, and after treatment.

What is the life expectancy?

Over the past few years, advances in technology have led to a gradual increase in the number of people who are cured of Pancoast tumors. But there is still a lot to learn about this disease. The five-year survival rate for people with early-stage, surgically treatable Pancoast tumors is between 30% and 50% . That means that about half of people diagnosed with early-stage Pancoast tumors are still alive five years after diagnosis. But it’s important to remember: These survival rates are just estimates. They don’t tell you exactly how long you will live or how well a particular treatment will work for you. Talk to your doctor to understand exactly how this cancer affects you.

When should you seek medical advice?

If you have severe shoulder pain, arm pain, arm weakness, or other symptoms of a Pancoast tumor, you should see a doctor immediately. Early detection is key.

What questions should you ask the doctor?

If you or a loved one is diagnosed with a Pancoast tumor, you may want to ask your doctor these questions:

• Where is the tumor?
• Has it spread to surrounding tissues?
• Has it spread to distant parts of the body?
• What stage of cancer do I have?
• What treatment options do I have?
• Will I be able to work during treatment?
• How long does treatment usually take?
• How is my outlook?

Is this a Pancoast tumor or a pinched nerve?

Some people with Pancoast tumors say that their symptoms started with a "pinched nerve" feeling . If you have this kind of pain and it lasts for more than two weeks, let a doctor know. It may not be normal.

Final Take-Home Message

Pancoast tumors start in the upper part of your lungs. They are different from other types of lung tumors because they are difficult to detect in the early stages. Finding out you have a Pancoast tumor can be a very confusing experience. It can be overwhelming to plan what to do next.

But remember, your doctor is there to help you. Ask him or her for more information about your specific situation. If you can, join a support group, either in person or online. Talking to others who are going through the same things you are going through can be very beneficial for your mental, emotional, and spiritual health. Never suffer alone.
