What are soft tissue sarcomas in the leg?
- Adult fibrosarcoma: Between the ages of 20 and 60, adult fibrosarcoma typically develops in the connective tissues of the arms, legs, or trunk.
- Alveolar soft part sarcoma: Young adults most frequently acquire alveolar soft part sarcoma in their legs.
- Clear cell sarcoma: Arm or leg tendons are frequently the site of origin for clear cell sarcoma. Of those with diagnoses, half are older than 39.
- Epithelioid sarcoma: The skin under the hands, forearms, lower legs, or feet is where epithelioid sarcoma forms. Teens and young adults are the age group most affected.
- Fibromyxoid sarcoma: Usually, fibromyxoid sarcoma begins as a painless growth in the arms, legs, or trunk.
- Liposarcomas: Liposarcoma often affects individuals between the ages of 50 and 65. It begins in fat tissue. They frequently appear in the rear of the inner abdomen, behind the knee, or in the thigh.
- Myxofibrosarcoma: People over 65 are most likely to develop myxofibrosarcomas in their arms and legs.
- Undifferentiated pleomorphic sarcoma: Older persons typically have undifferentiated pleomorphic sarcoma in their arms or legs.
Risk factors for soft tissue sarcomas
- receiving radiation therapy
- Neurofibromatosis
- Li-Fraumeni syndrome
- Gardner syndrome
- harm to your lymphatic system
- vinyl chloride
- arsenic
- pesticides containing phenoxyacetic acid and dioxin
What are the symptoms of soft tissue sarcomas in the leg?
- a growing, painless lump
- swelling
- increasing irritation or suffering as it presses against other tissue
- restricted movement
- noticeable deforming
- trouble walking
- limping
How are soft tissue sarcomas in your leg diagnosed and staged?
- X-rays
- ultrasound
- CT (Computerised Tomography) scans
- scanning using positron emission tomography (PET)
- imaging using magnetic resonance (MRI)
Soft tissue sarcoma stages
- tumor size
- how many lymph nodes it has infiltrated
- whether it has metastasized, or spread to far-off places
- cancer grade, a scale from 1 to 3 that indicates how aggressive the cancer is
Stage | Description |
---|---|
1A | The cancer hasn't spread to other areas and is less than two inches across. It is either grade 1 or not specified. |
1B | The malignancy is more than two inches in diameter. It hasn't extended to far-off places. It is either grade 1 or not specified. |
2 | The cancer hasn't spread to other tissues and is less than two inches in diameter. It's either third or second grade. |
3A | The malignancy has not spread to other tissues and measures between two and three inches across. It's either third or second grade. |
3B | The cancer has not spread to other tissues and is more than 3.9 inches wide. It's either third or second grade. |
4 | The cancer has progressed to distant regions, lymph nodes, or both. Any size or grade will do. |
How are soft tissue sarcomas in your leg treated?
- Mohs surgery (used for skin cancer lesions): Mohs surgery involves slicing the tumour into extremely small layers until the malignancy is completely gone. Surgeons can remove the least amount of tissue feasible thanks to it.
- Wide local excision: The tumour is excised along with some surrounding tissue.
- Limb-sparing surgery: If necessary, grafts are used to restore the limb after the tumour is removed.
- Amputation: Amputation is the complete removal of a limb. Seldom is it necessary in cases of soft tissue sarcoma.
Are soft tissue sarcomas of the leg curable?
For many people, soft tissue sarcomas are treatable. If you have a non-aggressive subtype and your tumour is discovered before it spreads to other tissues, your cancer has the best chance of being cured.
What is the outlook for those who have leg soft tissue sarcomas?
Stage | 5-year relative survival rate |
---|---|
Localized | 81% |
Regional | 56% |
Distant | 15% |
All stages | 65% |
Takeaway
One of the most typical places for soft tissue sarcomas to occur is the leg. Any soft tissue, including muscle, fat, and connective tissue, can produce sarcomas.
Compared to malignancies that grow inside the abdomen, soft tissue sarcomas that occur in the leg typically have a better prognosis. Surgical excision of the tumour and surrounding tissue is frequently an effective treatment option, avoiding the need for amputation.
