High-risk objects
1. High risk factors of soft tissue sarcoma:
(1) Family history of tumor, especially with p53 and rb gene inactivation;
(2) A history of long-term exposure to chemical materials such as asbestos and dioxins;
(3) EB virus, HIV and other infection history;
(4) History of radiation or radiotherapy;
2. Four early signs of soft tissue sarcoma:
(1) Unexplained masses found on the body surface or near large joints and imaging examinations or masses that cannot be resolved for a long time after trauma;
(2) The mass continues to increase and does not relieve with changes in body position;
(3) Pain and joint dysfunction may appear, and gradually worsen;
(4) The local skin temperature of the tumor is often higher than that of the surrounding normal tissues, which may be accompanied by inflammatory manifestations such as redness and swelling.
Screening recommendations
Pay attention to the four early signs of soft tissue sarcoma, and go to the soft tissue tumor specialist in time for medical treatment if abnormalities occur.
1. Physical examination: The tumor is generally qualitatively preliminarily qualitative based on 7 aspects including the location, size, boundary, mobility, tenderness, skin temperature and accompanying symptoms of the tumor.
2. Imaging: B-ultrasound, X-ray, CT, MRI, etc. For extremity soft tissue sarcomas, MRI is preferred over CT. High-risk patients should undergo chest CT to rule out lung metastases. At the same time, the regional lymph nodes should be checked.
3. Biopsy: soft tissue sarcoma biopsy, including needle biopsy and incision biopsy. Fine needle or thick needle puncture, if necessary, CT or B-ultrasound guidance. Difficulty or failure of puncture can be performed by surgical incision biopsy.
Prevention advice
1. Avoid radiation and strong ultraviolet radiation, increase the intake of β-carotene and carotenoids, vitamin C and E;
2. Reduce the contact of chemical materials, screen for virus infections, and treat infections in a standardized and timely manner;
3. Eat a reasonable diet, enhance physical exercise, and improve immunity.
