Synovial sarcomas are a type of cancer that originates from the synovial tissue in the human body. The spelling of this word can be explained through IPA phonetic transcription as /sɪˈnoʊviəl sɑrkˈoʊməz/. The first syllable "syn" comes from the Greek word "synovion" meaning "joint" while the second syllable "ovial" comes from "ovium" which means "egg". The ending "sarcoma" is derived from "sarx" meaning "flesh". Hence, the term synovial sarcomas denotes a cancer that affects the tissues of the joint, often manifesting as a lump in the leg or arm.
Synovial sarcomas are a type of rare and aggressive soft tissue cancers that typically arise near the joints, predominantly in the extremities, such as the arms and legs. Despite the name, synovial sarcomas do not originate from the synovial tissue but display similar characteristics. The tumors often occur in young adults between the ages of 15 and 40, although they can affect individuals of any age.
Synovial sarcomas are characterized by their unique genetic abnormality known as the SYT-SSX fusion gene. This genetic alteration often leads to the formation of a specific translocation between the short arm of chromosome 18 and either the X, or less frequently, the Y chromosome. The exact cause of synovial sarcomas is unknown, and there are no established risk factors associated with their development.
Clinically, synovial sarcomas present as a painless, slow-growing mass that may become painful or increase in size as the tumor progresses. Depending on the location and stage of the tumor, individuals may also experience functional limitations and swelling in the affected area. Diagnosis is confirmed through a combination of imaging tests, such as X-rays, MRI scans, and biopsies.
Treatment for synovial sarcomas usually involves a multidisciplinary approach, including surgery, radiation therapy, and chemotherapy. The choice of treatment depends on the size, location, and stage of the tumor, as well as the individual's overall health. Prognosis for synovial sarcomas varies widely, with factors such as tumor size, location, and the presence of metastasis significantly influencing the outcome. The five-year survival rate ranges from approximately 40% to 70%, emphasizing the importance of early detection and prompt intervention.
The word "synovial sarcoma" is derived from Greek and Latin roots.
"Synovial" comes from the Greek word "synovia", which means "joint fluid". Synovial fluid is a lubricating fluid found in the cavities of synovial joints (such as the knee, shoulder, or hip), ensuring smooth movement of the joints.
"Sarcoma" is derived from the Greek word "sarx", meaning "flesh". It refers to a malignant (cancerous) tumor that develops in the connective tissues of the body, including muscles, bones, tendons, or cartilage.
The term "synovial sarcoma" was coined because these tumors were initially believed to originate from the synovial tissue or synovial cells around the joints.
