Common Signs and Symptoms of Muscle Cancer

Muscle cancer, also known as sarcoma, can manifest in various ways depending on the type and location of the tumor. Here are some common signs and symptoms to look out for:

• A noticeable lump or swelling: This is often the first sign of muscle cancer, and it can be felt through the skin (1).
• Pain: As the growth presses on nerves or muscles, pain can occur (1). The location and severity of the pain will depend on where the tumor is located.
• Abdominal pain: If the cancer is in the abdominal area, you may experience persistent or worsening stomach pain (2, 11).
• Blood in stool or vomit: In some cases, muscle cancer can cause bleeding in the digestive tract, leading to blood in stool or vomit (2, 10).
• Black, tarry stools: This is a sign of internal bleeding and should be taken seriously (2).
• Unexplained fatigue: As the cancer grows, it can cause extreme tiredness due to the body's increased energy expenditure (14).
• Reduced appetite: Muscle cancer can lead to a decrease in appetite, resulting in unintended weight loss (5, 14).
• Abdominal bloating: Some people may experience abdominal bloating or discomfort as the tumor grows (11).

Other Possible Symptoms

In addition to these common signs and symptoms, muscle cancer can also cause:

• Headache: If the cancer is in the head or neck area, you may experience headaches or other neurological symptoms (10).
• Bleeding in the nose, throat, or ears: In some cases, muscle cancer can cause bleeding in these areas (10).

Important Note

It's essential to seek medical attention if you're experiencing any of these symptoms, especially if they persist or worsen over time. Early detection and treatment can significantly improve outcomes for muscle cancer patients.

Diagnostic Tests for Muscle Cancer

Muscle cancer, also known as soft tissue sarcoma, can be diagnosed using various tests and procedures. Here are some of the diagnostic tests used to diagnose muscle cancer:

• Imaging tests: Imaging tests such as X-rays, CT scans, MRI scans, and PET scans may be used to visualize the tumor and determine its size and location [5][8].
• Biopsy: A biopsy is a procedure in which a small sample of tissue is removed from the tumor and examined under a microscope. This can help confirm the diagnosis of muscle cancer [1][9].
• Blood tests: Blood tests may be used to measure the level of certain substances, such as C-reactive protein (CRP), that can indicate inflammation or infection in the body [2].
• Muscle biopsy: A muscle biopsy involves removing a small piece of tissue from the affected muscle and examining it under a microscope. This can help confirm the diagnosis of muscle cancer [6][13].

Other Diagnostic Tests

In addition to these tests, other diagnostic procedures may be used to diagnose muscle cancer, including:

• Flow cytometry: Flow cytometry is a laboratory test that uses a special machine to analyze cells and determine their characteristics [7].
• Ultrasound: Ultrasound is a non-invasive imaging test that uses sound waves to create images of the body. It can be used to visualize the tumor and determine its size and location [12].

Importance of Accurate Diagnosis

Accurate diagnosis is crucial in developing an effective treatment plan for muscle cancer. A thorough and accurate cancer diagnosis involves performing a complete array of diagnostic tests, reviewing the patient's medical records and health history, and conducting a physical exam [15].

Treatment Options for Muscle Cancer

Muscle cancer, also known as soft tissue sarcoma, can be treated with a combination of chemotherapy, radiation therapy, and surgery. The treatment approach depends on the size, type, and location of the cancer, as well as how quickly it grows.

• Chemotherapy: This is a common treatment for muscle cancer, especially if the cancer has spread to other parts of the body. Chemotherapy uses medications to kill cancer cells and can be used alone or in combination with other treatments.
• Radiation Therapy: Radiation therapy uses high-energy rays to kill cancer cells. It can be used before surgery (neoadjuvant radiation) to shrink the tumor, or after surgery (adjuvant radiation) to kill any remaining cancer cells.
• Surgery: Surgery is often the primary treatment for muscle cancer and involves removing the tumor along with a margin of healthy tissue around it.

Targeted Therapy and Immunotherapy

In addition to traditional treatments like chemotherapy and radiation therapy, targeted therapy and immunotherapy are also being explored as potential treatment options for muscle cancer. Targeted therapy uses medications that specifically target cancer cells, while immunotherapy uses the body's immune system to fight cancer.

• Targeted Therapy: Targeted therapy involves using medications that specifically target cancer cells, reducing harm to healthy cells.
• Immunotherapy: Immunotherapy uses the body's immune system to fight cancer. It can help stimulate the immune system to recognize and attack cancer cells.

Reconstruction and Palliative Care

After surgery, reconstruction of the surgical area is often necessary to restore function and appearance. Palliative care is also an important aspect of treatment for muscle cancer patients, as it focuses on providing relief from symptoms, pain, and stress.

• Reconstruction: Reconstruction involves repairing or rebuilding tissues that were damaged during surgery.
• Palliative Care: Palliative care provides relief from symptoms, pain, and stress associated with cancer and its treatment.

The differential diagnosis of muscle cancer, also known as skeletal muscle metastases or soft tissue sarcoma, involves a wide range of conditions that can mimic the presentation of cancer in muscles.

Common Differential Diagnoses

• Sarcomas: These are rare cancers that begin in the muscle, fat, fibrous tissue, blood vessels, or other supporting tissue of the body. They can be difficult to distinguish from metastatic disease.
• Myopathy: This refers to a group of diseases that affect the muscles and can cause pain, weakness, and swelling.
• Intramuscular abscess: An abscess is a pocket of pus that forms in the muscle, often as a result of an infection. It can be mistaken for cancer due to its similar presentation.

Other Conditions to Consider

• Muscle hemangioma: A benign tumor composed of blood vessels.
• Intramuscular ganglion: A type of cyst that can form in the muscle.
• Myxoma: A rare, benign tumor that can occur in the muscle.
• Ischiorectal bursitis: An inflammation of the bursa (fluid-filled sac) located near the muscles and joints.
• Benign muscle calcifications: Such as myositis ossificans or calcific tendinitis.

Importance of Accurate Diagnosis

Accurate diagnosis is crucial in differentiating between these conditions, as treatment approaches can vary significantly. For example, sarcomas require aggressive treatment with chemotherapy and/or radiation, whereas abscesses may be treated with antibiotics and drainage.

According to [10], the differential diagnosis of skeletal muscle metastasis mainly includes sarcoma, myopathy, and intramuscular abscess. Differentiating a muscle metastasis from sarcoma is of paramount importance because the treatment approach is quite different [15].
