Synovial sarcoma is a rare and aggressive soft tissue sarcoma. In the early stages of the condition, it may cause no noticeable signs or symptoms. However, as the tumor grows larger, affected people may notice a lump or swelling.

Approach Considerations. There are no contraindications for surgical treatment of synovial cell sarcoma, which is potentially life-saving. There is a relative contraindication for treating these patients in primary centers. Early referral to tertiary centers for definitive treatment must be preferred.

The overall relative 5-year survival rate of people with soft tissue sarcomas is around 50% according to statistics from the National Cancer Institute (NCI). These statistics include people with Kaposi sarcoma, which has a poorer outlook than many sarcomas. The NCI doesn’t use the AJCC staging system.

Prognosis in synovial sarcoma patients is influenced by the quality of surgery patients receive and the characteristics of the disease (including tumor size, local invasiveness, histological subtype, presence of metastases, and lymph node involvement).

The long-term outlook (prognosis) for people with synovial sarcoma depends on many factors, including the size, grade and stage of the tumor; where the tumor is located; and the affected person's age and overall health. In general, synovial sarcoma has a survival rate of 50-60% at 5 years and 40-50% at 10 years. Recurrence has been reported up to 69 months after treatment and suggests a worse prognosis with low survival rates.

This is a better way to see the effect of the cancer on survival. To get 5-year survival rates, doctors have to look at people who were treated at least 5 years ago. If treatment has improved since then, people now being diagnosed with soft tissue sarcoma may have a more favorable outlook.

There are no well-established risk factors for synovial sarcoma, but the disease is associated with the chromosomal translocation t(X;18) (p11;q11). This means that parts of chromosome 18 and chromosome X have switched places in synovial sarcoma tumor cells.

Surgical excision is still the cornerstone of treatment for synovial cell sarcoma. A tumor-free margin of 1-3 cm is recommended.Maximal care must be taken to reduce the risk of local recurrence. Careful preoperative planning is essential.

Synovial sarcoma occurs most commonly in the young, representing about 8% of all soft tissue sarcomas but about 15–20% of cases occur in adolescents and young adults. The peak of incidence is in the third decade of life, with males being affected more often than females (ratio around 1.2:1).

A synovial sarcoma (also known as: malignant synovioma) is a rare form of cancer which occurs primarily in the extremities of the arms or legs, often in close proximity to joint capsules and tendon sheaths. As one of the soft tissue sarcomas, it is one of the rarest forms of soft tissue cancer.

life expectancy for synovial sarcoma
Life expectancy for Synovial sarcoma has a survival rate of 50-60% at 5 years and 40-50% at 10 years. The life expectancy for Synovial Sarcoma has a survival rate in between 50 percent and 60 percent at 5 years and in between 40 percent and 50 percent at 10 years.
