Scalenus Muscle Cancer

Neck muscle cancers are rare compared to other cancers of the head and neck; however, when they do occur, they require careful diagnosis and timely treatment. The scalene muscles (sometimes referred to as scalenus muscles) are located on the side of the neck and serve important functions in posture and breathing. Cancer in these muscles is generally categorized among soft-tissue sarcomas.

Anatomy and Function of the Neck Scalene (Scalenus) Muscles

Understanding the normal anatomy of the neck and its muscles is an important first step. The scalene muscles—often grouped as the anterior, middle, and posterior scalene muscles—help support the neck and assist breathing. Even though the term “pleuralis” is sometimes added, here we focus on what is generally known about the scalene muscles.

Structure and Location

• Location:

  • The scalene muscles are located in the lateral part of the neck. They lie deep to the sternocleidomastoid muscle and extend from the cervical (neck) spine to the upper ribs.

  • They are important anatomical landmarks in the neck, helping to define spaces for nerves and blood vessels.

• Structure:

  • They are narrow, strap‑like muscles that are sometimes grouped into three parts: anterior, middle, and posterior scalene. Each has specific attachments and roles.

Origin and Insertion

• Origin (Where the muscles begin):

  • The muscle fibers generally originate from the transverse processes (the side projections) of the cervical vertebrae.

• Insertion (Where the muscles attach):

  • They insert onto the first rib (and sometimes the second rib), providing a connection that is critical for their function during breathing and stabilizing the neck.

Blood Supply

• Key Arteries:

  • The blood supply to these muscles commonly comes from small branches of the subclavian and thyrocervical trunk arteries.

  • A good blood supply is essential for muscle function and repair, and any interruption may affect healing.

Nerve Supply

• Nerve Sources:

  • The scalene muscles are primarily controlled by cervical spinal nerves. Nerves such as those from the brachial plexus (a network of nerves in the neck) play an important role.

  • Proper nerve supply ensures that the muscle contracts and relaxes appropriately.

Functions of the Scalene Muscles

Here are six important functions of the scalene muscles:

1. Breathing Assistance:

   • They help elevate the first rib during heavy breathing, acting as accessory muscles in respiration.

2. Neck Stabilization:

   • By anchoring the cervical spine, these muscles help maintain proper posture and support head movement.

3. Lateral Neck Flexion:

   • They allow the neck to bend sideways (laterally flex).

4. Rotation of the Neck:

   • Contribute to turning the head.

5. Assisting in Forced Expiration:

   • Although not their primary function, they support forced expiration in certain situations.

6. Protection of Vital Structures:

   • Their arrangement helps protect the nerves and blood vessels that pass between the neck and the thorax.

Types of Neck Scalenus (Scalene) Muscle Cancer

Cancers affecting the soft tissues of the neck, including the scalene muscles, are generally grouped under soft-tissue sarcomas. Although these cancers are rare, several types have been identified:

1. Rhabdomyosarcoma:

   • A cancer that arises from skeletal (striated) muscle tissue. It is more common in children but can affect adults.

2. Leiomyosarcoma:

   • Originates from smooth muscle tissue. Although more commonly found in other areas, it can rarely occur in neck muscles.

3. Fibrosarcoma:

   • A cancer that begins in fibrous tissue. It may affect supportive tissue in the muscles.

4. Undifferentiated Pleomorphic Sarcoma:

   • A type of cancer with no clear cell origin, sometimes affecting soft tissues in the neck.

5. Synovial Sarcoma:

   • Often located near joints or within connective tissue. It can sometimes be found in the neck area.

6. Angiosarcoma:

   • A rarer type of sarcoma that originates in the blood or lymph vessels and can involve muscle tissue.

Even though these tumors have specific names, treatment and prognosis are based on the tumor’s size, location, grade, and whether it has spread.

When to See a Doctor

Early detection is key in managing any cancer. It is important to see a doctor if you experience one or more of the following warning signs:

• A lump or mass in the neck that grows over time.

• Persistent neck pain or stiffness that does not improve.

• Unexplained weight loss or loss of appetite.

• Swelling or visible changes in the neck area.

• Difficulty swallowing, breathing, or speaking.
