What is a retroperitoneal sarcoma?
Retroperitoneal sarcoma is a relatively rare type of cancer, which represents only 15 percent of all soft tissue sarcomas and less than 1 percent diagnosed cancer. This type of cancer grows in cells called mesenchymal cells in several types of tissues. Several treatment procedures are available for retroperitoneal sarcoma, but the success of these treatments is variable due to the wide range of histological types of cancer that exist. This type of cancer can grow in several types of cells, including fat, muscle, connective tissue and nerve tissue, and each type reacts differently to treatment.
The overall rarity of the retroperitoneal sarcoma means that each subtype is even more rare. For this reason, there are few current data on symptoms, forecasts and treatment of this type of cancer. Most of the studies that exist have combined data involving several decades of treatment of patients with different cancer subtypes and the results of such studies are highly variable.
Just a single symptom withIt represents a common feature of retroperitoneal sarcoma. This is the presence of matter in the abdomen. This is sometimes accompanied by other symptoms, but the matter is often the only symptom. When other symptoms are manifested, gastrointestinal bleeding, gastrointestinal obstruction and pain or swelling in the lower abdomen may include.
The diagnosis of this cancer is usually made on the basis of diagnostic imaging tests, as well as blood tests and other tests. After cancer identification, a biopsy must be performed to determine the histological type of cancer. This term applies to the type of cell that has become malignant, as well as new cancer -related proteins that produce or express newly malignant cells on their surfaces. Histological subtype of cancer often affects the decision on treatment and prognosis.
The three main treatments for retroperitoneal sarcoma are surgery, chemotherapy and radiation therapy. WhenCancer is non -invasive and sluggish, the treatment of choice is generally surgery. During the procedure, the surgeon removes as much of the tumor mass as possible. Surgery is then monitored by chemotherapy or radiation therapy to kill any cancer cells that remain. In some types of sarcoma, this additional treatment after surgery may improve the outcome of the treatment and improve the patient's prognosis.
Successful treatment of this type of cancer is unusual, mainly because the disease is often diagnosed late in its progression. If a recurrence after initial treatment, this will probably happen within five years. Metastases or the spread of cancer are most commonly found in the liver or lungs. When the disease is recurring or metastatic, the chances of successful surgery decrease significantly.
