What is retroperitoneal tumor

summary

Retroperitoneal tumor can be divided into primary retroperitoneal tumor and malignant retroperitoneal tumor according to the different location of the disease. The situation is complex. The number of patients in China is more than 10000 every year. Let's take a detailed look at what is retroperitoneal tumor.

What is retroperitoneal tumor

First of all, retroperitoneal tumors mainly include primary retroperitoneal tumors originating in the potential retroperitoneal space and secondary retroperitoneal tumors metastasized from other sites. Retroperitoneal tumor usually refers to primary retroperitoneal tumor, most of which belong to soft tissue tumor, accounting for 15% of the latter. Primary retroperitoneal tumors are rare, accounting for less than 1% of malignant tumors. Malignant tumors accounted for 80% of retroperitoneal tumors, and the most common tumor was sarcoma derived from mesenchymal tissue, accounting for 42%.

Secondly, retroperitoneal tumors usually have no obvious symptoms and signs in the early stage because of their deep location. When patients feel abdominal fullness or feel abdominal mass, the tumor is often huge. Because retroperitoneal tumor itself is lack of specific clinical manifestations, it is rarely able to be detected early. Therefore, even if it is not for the purpose of preventing this disease, regular physical examination should be carried out to avoid potential diseases.

Finally: although it is difficult to make a definite diagnosis of retroperitoneal tumor only by clinical symptoms and signs, it is not difficult to make a localization diagnosis based on enhanced CT or MRI because of the large size of the tumor. It is difficult to judge the prognosis of qualitative diagnosis by preoperative clinical and imaging findings. As the gold standard, pathological diagnosis is often obtained after surgery or puncture, and the next treatment strategy is formulated accordingly.

matters needing attention

The harm of retroperitoneal tumor is relatively large, because it exists in the body, there is no obvious symptoms, it is best to have a regular physical examination plan, so that some symptoms are not obvious, can also be found in time.
