Sarcoma

Sarcomas are cancers that start in bones, muscles, connective tissues, blood vessels or fat, and can be found anywhere in the body. There are more than 50 different types of sarcoma, which fall into two main categories: bone cancers and soft tissue cancers.

Key Facts

  • An estimated 13,460 new cases of soft tissue sarcomas and 3,610 new cases of bone cancers will be diagnosed in the U.S. in 2021, with around 7,410 deaths expected to result from the diagnosis.
  • Sarcomas are rare in adults and make up approximately 1% of all adult cancer diagnoses.
  • Sarcomas are relatively more common among children. Between 1,500 and 1,700 children are diagnosed with a bone or soft tissue sarcoma in the U.S. each year. This makes up about 15% of cancers in children under the age of 20.
  • The overall relative five-year survival rate for people with soft tissue sarcoma is around 65% and for people with bone cancer, the overall relative five-year survival rate is 70%.
  • When the sarcoma starts in an arm or leg, the five-year survival rates are slightly higher for each stage when compared with sarcoma that starts in other locations.

Signs and Symptoms

A symptom is a change in the body that a person can see and/or feel. A sign is a change that the doctor sees during an examination or on a laboratory test result. If you have any of the symptoms below, it does not mean you have cancer but you should see your doctor or health care professional so that the cause can be found and treated, if needed.

Soft Tissue Sarcoma

  • A lump that is increasing in size or becomes painful
  • A lump of any size that is located deep within a muscle
  • Abdominal pain that’s getting worse
  • Blood in your stool or vomit
  • Black, tarry stools

Bone Cancer

  • Bone pain that becomes constant over time and worsens with activity.
  • Swelling near pain area that happens later; may feel lump depending on location
  • Neck bone cancers may cause a lump in the throat; Difficulty to swallow or breathe.
  • Bone cancer most of time does not fracture; Feeling sudden bone pain after soreness for months may indicate fracture.
  • Cancer in spine bones can press on nerves, causing numbness, tingling or weakness.

Sarcoma Origin Identified

Cancer is anything but a straightforward disease; one tumor type can be entirely different from another not only in location, but causal agent and origin. There is differentiation even within the same type of cancer. Take sarcoma, which is in fact an umbrella term for nearly 100 cancers originating in the skeleton or the soft parts of the body. Some affect the young, others the elderly. But now a study out of Sweden is bringing the starting points of some sarcomas into focus by identifying for the first time an interaction between specific proteins. “We now know which mechanisms to shine the spotlight on,” says Pierre Åman, Professor of Tumor Biology at Sahlgrenska Academy, University of Gothenburg, the corresponding author behind an article published in the journal EMBO Reports. Osteosarcomas develop in bone; liposarcomas form in fat; rhabdomyosarcomas form in muscle; Ewing sarcomas form in bone and soft tissue, and Kaposi’s sarcoma is practically synonymous with HIV/AIDS infection. However, among cancers, sarcoma is relatively uncommon; in the United States, around 12,750 people — 7,240 men and boys and 5,510 women and girls  — will be diagnosed with a soft-tissue sarcoma (STS) this year. The overall five-year survival rate for people with STS is around 65 percent; if the cancer is caught early and has not left its point of origin, the survival rate can be as high as 81 percent; if the sarcoma has spread to another area of the body, the 5-year survival rate falls precipitously to 16 percent. However, rates vary based on the specific type and the stage, or extent, of the sarcoma, showing how even just one type of cancer can have wildly different subsets. In the Swedish study, the 15 or more different forms of sarcoma studied were found to be caused by mutations in the FET family of proteins, involved in the regulation of lifespan and stress resistance, acting partially through the insulin/IGF-signaling pathway. The new results show that most of the tumor-altered FET proteins bind to another protein complex, SWI/SNF, which regulates gene activity, cell maturity and growth. This interaction results in SWI/SNF misregulation and, accordingly, disruptions in the genetic programming within a cell. The misregulation is a mechanism common to all the 15 or more forms of tumor caused by mutations in the FET genes. This now gives oncologists a solid target upon which to aim their efforts, and could clear the way for some type of screening technology. Importantly, the FET family is already a focus of scientific inquiry: they are of medical interest because chromosomal rearrangements of their genes promote not only various sarcomas, but because point mutations in FUS or TAF15 (both FET) can cause neurodegenerative diseases such as amyotrophic lateral sclerosis and frontotemporal lobar dementia. Because of that, “There are already an abundance of new drug candidates that affect this protein complex and are being tested on other diseases,” Åman says. “With the discoveries we’ve now made, we can test the same candidates on these forms of sarcoma as well.” July is Sarcoma Awareness Month, and studies such as Åman’s continue to shed light on the cancer’s ultimate […]
