Soft tissue tumors: Frequently asked questions and answers
1. What are the early symptoms of soft tissue tumors?
The most common presentation of soft tissue tumors is a painless, enlarging mass.Tumor enlargement compressing nerves can cause pain and numbness.Tumors located in the limbs may affect joint mobility.
2. What are the common types of soft tissue tumors?
There are more than 50 types of soft tissue tumors.Common types include liposarcoma, leiomyosarcoma, synovial sarcoma, malignant peripheral nerve sheath tumor, and gastrointestinal stromal tumor (GIST).
3. What are the surgical treatment methods for soft tissue tumors?
Wide resection is the primary treatment for soft tissue tumors; it involves removing the tumor along with surrounding normal tissue to ensure negative margins.For limb tumors, limb-sparing surgery is prioritized, though amputation may be necessary in some cases.
4. What is minimally invasive treatment for soft tissue tumors?
Laparoscopic surgery is used to resect retroperitoneal and abdominal soft tissue tumors, offering small incisions and quick recovery.Image-guided percutaneous needle biopsy is used to obtain a pathological diagnosis.
5. Why is combined radiochemotherapy used for soft tissue tumors?
High-grade soft tissue tumors carry a high risk of postoperative recurrence; adjuvant radiotherapy can reduce the rate of local recurrence.Chemotherapy is used for specific types, such as synovial sarcoma and rhabdomyosarcoma.
6. How can benign and malignant soft tissue tumors be distinguished?
Benign tumors grow slowly, have clear boundaries, and are small in size.Malignant tumors grow rapidly, have indistinct boundaries, and are large.MRI imaging aids in assessment.Definitive diagnosis requires pathological examination.
7. Follow-up after soft tissue tumor treatment?
Undergo regular post-operative MRI or CT scans of the surgical site (every 3–6 months for the first 2 years).High-grade tumors require more frequent follow-up.Monitor for lung metastasis via chest CT scans.
