What is the most commonly associated with retroperitoneal sarcoma?

The most common types of retroperitoneal soft tissue sarcomas in adults vary from study to study. However, in most studies, the most frequently encountered cell types are liposarcomas, leiomyosarcomas and malignant fibrous histiocytomas (MFH) [2].

What is retroperitoneal sarcoma?

The retroperitoneum is the space between the peritoneum and the posterior abdominal wall that contains the kidneys and associated structures, the pancreas, and part of the aorta and inferior vena cava. Approximately 15 percent of soft tissue sarcomas arise in the retroperitoneum.

What causes retroperitoneal liposarcoma?

Certain risk factors have been shown to predispose individuals to developing soft tissue sarcomas, such as liposarcoma, including: prior radiation, familial cancer syndromes, damage to the lymph system, and long term exposure to certain toxic chemicals such as vinyl chloride, a chemical used to make plastic.

What is the cause of sarcoma cancer?

DNA mutations in soft tissue sarcoma are common. But they’re usually acquired during life rather than having been inherited before birth. Acquired mutations may result from exposure to radiation or cancer-causing chemicals. In most sarcomas, they occur for no apparent reason.

Where do soft tissue sarcomas grow?

Adult soft tissue sarcomas can form almost anywhere in the body, but are most common in the head, neck, arms, legs, trunk, abdomen, and retroperitoneum. Soft tissue sarcoma forms in soft tissues of the body, including muscle, tendons, fat, blood vessels, lymph vessels, nerves, and tissue around joints.

Can retroperitoneal sarcoma be cured?

For patients with retroperitoneal sarcoma, surgery is still the only chance for cure. However, these are not straightforward operations at all. Because of their large size and the limited space in the rest of the abdomen, these tumors often touch, compress, displace or outright invade major organs and blood vessels.

What is the best treatment for sarcoma?

Small low-grade sarcomas can usually be effectively removed by surgery alone. Those that are high grade and larger than 2 inches (5 cm) are often treated with a combination of surgery and radiation therapy. Radiation therapy or chemotherapy may be used before surgery to shrink the tumor and make removal easier.

Is sarcoma cancer serious?

A sarcoma is considered stage IV when it has spread to distant parts of the body. Stage IV sarcomas are rarely curable. But some patients may be cured if the main (primary) tumor and all of the areas of cancer spread (metastases) can be removed by surgery.

What is the diagnosis and management of retroperitoneal sarcoma?

Retroperitoneal sarcoma (RPS) is a rare tumor whose diagnosis and management can be challenging and for which management requires a multidisciplinary team in a specialized center.

Is there such a thing as a retroperitoneal tumor?

Retroperitoneal tumors are extremely rare tumors occurring in the retroperitoneum. Retroperitoneal tumors are divided into benign tumors and malignant tumors, including retroperitoneal sarcoma. Approximately 70-80% of primary retroperitoneal soft-tissue tumors are malignant; however, these only account for 0.1-0.2% of all malignancies.

Where to get treatment for retroperitoneal sarcoma in Scotland?

In Northern Ireland, retroperitoneal sarcoma is diagnosed and treated across a number of hospitals in Belfast. People in Scotland should be referred to the Scottish Sarcoma Service for treatment.

When to consider neoadjuvant therapies for sarcoma?

Neoadjuvant therapies (chemotherapy, external beam radiation, or combination radiation and chemotherapy) are safe in well-selected patients and may be considered after careful review by a multidisciplinary sarcoma tumor board when the recurrence risk is high.
