Alveolar Soft Part Sarcoma (ASPS)

Understanding Alveolar Soft Part Sarcoma (ASPS)

Alveolar Soft Part Sarcoma (ASPS) is a rare, slow-growing soft tissue cancer that originates in the deep soft tissues, most commonly in the legs, arms, or pelvis. It is characterized by a unique alveolar-like appearance under the microscope. Despite its slow growth, ASPS is known for its high potential to metastasize (spread) to other organs, particularly the lungs, brain, and bones. ASPS is more prevalent in adolescents and young adults, and while it often grows slowly, it can become aggressive once it spreads.

Common Signs and Symptoms of ASPS:

• Painless Mass:

  • A slowly enlarging, often painless mass or lump in the soft tissues, most frequently found in the extremities or pelvic region.

• Localized Discomfort:

  • Although initially painless, the tumor may eventually cause discomfort or pain as it enlarges or compresses surrounding tissues.

• Metastatic Symptoms:

  • If the cancer spreads, symptoms may include shortness of breath or chest pain (lung involvement), neurological symptoms such as headaches or seizures (brain involvement), and bone pain or fractures (bone involvement).

• General Symptoms:

  • In advanced stages, systemic signs like fatigue, unexplained weight loss, or general malaise may occur.
