Sarcoma: Understanding Symptoms and Treatment

Sarcoma: Symptoms and Treatment

Sarcoma is a rare type of cancer that arises from transformed cells of mesenchymal origin. This means it can develop in bone, cartilage, fat, muscle, vascular, or hematopoietic tissues. Due to its rarity and diverse types, sarcoma presents unique challenges in diagnosis and treatment. 

What is Sarcoma?

Sarcoma encompasses a broad group of cancers that originate in the connective tissues of the body. Unlike carcinomas, which are more common and arise from epithelial cells, sarcomas can occur in various parts of the body and affect different tissue types.

Types of Sarcoma

Sarcomas are broadly categorised into two main types:

Soft Tissue Sarcomas:

  • These develop in soft tissues like fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues.
  • Common types include liposarcoma (fat), leiomyosarcoma (smooth muscle), and angiosarcoma (blood vessels

Bone Sarcomas:

  • These originate in bone cells.
  • Common types include osteosarcoma (bone), Ewing's sarcoma (bone or soft tissue), and chondrosarcoma (cartilage).

Symptoms of Sarcoma

The symptoms of sarcoma can vary greatly depending on its location and type. However, some common signs and symptoms include:

  • Lump or Swelling: Often painless, but may cause discomfort if pressing against nerves or muscles.
  • Pain: Especially in the case of bone sarcomas, which can cause bone pain.
  • Restricted Movement: If the sarcoma is near a joint, it may limit movement.
  • Unexplained Weight Loss and Fatigue: General symptoms that may indicate cancer.

Diagnosis of Sarcoma

Diagnosing sarcoma typically involves several steps:

  • Medical History and Physical Examination: Initial evaluation to understand symptoms and risk factors.
  • Imaging Tests: Such as X-rays, CT scans, MRI scans, and PET scans to visualise the tumour.
  • Biopsy: A sample of the suspicious tissue is taken and examined under a microscope to confirm the diagnosis and determine the type of sarcoma.
  • Genetic Testing: Sometimes, genetic tests are conducted to identify specific mutations that can guide treatment.

Treatment Options for Sarcoma

Treatment depends on the type, location, and stage of the cancer. Common treatment options include:

Surgery:

  • The primary treatment for most sarcomas, aiming to remove the tumour completely.
  • Limb-sparing surgery is often possible, but in some cases, amputation may be necessary.

Radiation Therapy:

  • Often used before surgery to shrink tumours or after surgery to kill remaining cancer cells.
  • Can also be used as the main treatment if surgery isn’t an option.

Chemotherapy:

  • Used to kill cancer cells, particularly in types of sarcoma known to respond well to these drugs.
  • Often used in combination with surgery and/or radiation.

Targeted Therapy:

  • Drugs that target specific molecules involved in the growth and survival of cancer cells.
  • Used for certain types of sarcoma with specific genetic mutations.

Immunotherapy:

  • Uses the body’s immune system to fight cancer.
  • An emerging treatment option being explored in clinical trials.

Importance of Early Detection and Specialised Care

Due to the complexity and rarity, early detection and treatment at specialised centres with expertise in sarcoma care are crucial. Multidisciplinary teams that include surgical oncologists, medical oncologists, radiation oncologists, and pathologists are essential for optimal treatment planning and outcomes.

While rare, it is a serious and diverse group of cancers requiring specialised care for effective treatment. Awareness of its symptoms and risk factors, along with advances in diagnostic and treatment techniques, are vital for improving outcomes for those affected by this challenging disease.
