What are the symptoms of soft tissue tumors? What is the treatment protocol for soft tissue tumors?

Soft tissue tumors, most of them are soft tissue malignant tumors, that is, sarcomas, and some belong to soft tissue benign tumors, and the main symptoms generally show are the formation of local masses, which may be adhesion and fixation with surrounding tissues, and are not easy to move, or have a feeling of tenderness. If it is a soft tissue sarcoma, it is generally necessary to strive for extended surgery**, and postoperative chemotherapy and radiotherapy**.

As the tumor grows, there may be swelling, pain and other discomforts, and there may be compression of the surrounding normal tissues, and there may also be distant metastasis, resulting in symptoms of metastasis site. At the same time, the pathological nature of soft tissue tumors needs to be clarified first, if it is a benign tumor, it can be resected by surgery to achieve the best effect, but if it is a malignant tumor, it is generally necessary to carry out a comprehensive anti-tumor program such as surgery and radiotherapy and chemotherapy.

In general, the symptoms of soft tissue tumors are progressive enlargement, fever, weight loss, and general malaise, but systemic symptoms are rare. Fibrosarcoma can occur anywhere, with the lower extremities occurring in up to about 50%. Mainly feet, ankles and lower legs, so the upper limbs are more hands, wrists and forearms, and this tumor can also grow on the trunk, retroperitoneum, parotid glands, oral mucosa, tonsils, mastoid process, etc.

There is also vasodilation, epidermal or mucosal hyperemia, and ulceration, overflow, or bleeding in advanced stages.

Tumors that grow in the limbs will have symptoms such as pimples and ulcers, while peritoneal soft tissue tumors will cause abdominal distention, pain, intestinal obstruction, etc. Usually benign primary tissue tumors do not need **, malignant tumors require surgery, chemotherapy, and radiotherapy.

Soft tissue sarcoma is a rare tumor, most of which are benign and a few are malignant, and the malignant one is called soft tissue sarcoma.

There are benign tumors and malignant tumors, and malignant tumors can develop into cancer.

At least 1 3 percent of benign tumors are lipomas, 1 3 percent are fibrous histiocytomas and fibromas, 10 percent are vascular tumors, and 5 percent are schwannomas. The type of tumor is related to the symptoms and location of the tumor, and the age and sex of the patient. Lipomas are non-painful and rarely occur in the hands, calves, and feet, and are very rare in children.

Multiple (hemangiomatory) lipomas are sometimes painful, most commonly in young people, and angioleiomyomas are often painful and often occur in the lower legs of middle-aged women. Half of all vascular tumors occur before the age of 20. 99% of benign soft tissue tumors occur in superficial areas, and 95% are less than 5 cm in diameter.

Soft tissue sarcomas can occur anywhere,3 4 in the extremities (most commonly in the thighs), 10% on the trunk, and 10% retroperitoneally. The proportion of males is slightly higher. Similar to other malignancies, the incidence of soft tissue sarcoma increases with age, with the mean age of onset being 65 years.

Among the tumors of the acral ends and trunk, 1 3 are superficial and have an average diameter of 5 cm, and 2 3 are located deep and have an average diameter of 9 cm. Retroperitoneal tumors are usually symptomatic when they grow to a larger size. Metastases can be detected in 1 in 10 patients at the time of diagnosis of the primary tumor (the lungs are the most common).

Overall, at least 1 in 3 patients with soft tissue sarcoma die due to swelling and rapid tumor retraction, and most of these deaths are due to lung metastases.

About 3 4 of soft tissue sarcomas can be histologically classified as high-grade malignant pleomorphic (malignant fibrous histiocytomatoid, MFH) sarcoma, liposarcoma, leiomyosarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumors, and 3 4 tumors are highly malignant (equivalent to grades 2-3 in the 3-grade classification system and 3-4 in the 4-level classification system). The distribution of histotyping varies over time and between different researchers, possibly due to changes in the concept of histotyping. The peak age of onset varies depending on the tumor, with embryonal rhabdomyosarcoma occurring almost exclusively in children, synovial sarcoma occurring mainly in young people, and liposarcoma and leiomyosarcoma being most common in older people.

1. Lumps: Patients often present with ** lumps, which can last for several months or more than a year. Malignant tumors with large and small masses grow rapidly and are large in size. Malignant tumors are usually larger than 5 cm in diameter. The boundaries of tumors that grow rapidly and are located in deep tissues are often not clear.

2. Pain: High-grade sarcoma is often accompanied by dull pain due to its rapid growth. If the tumour involves adjacent nerves, pain is the first symptom. The prognosis is often poor when sarcoma is painful, with pain occurring in only 27% of cases with successful limb salvage and up to 50% in the amputation group.

3. Hardness tumors with more fibers and smooth muscle components are harder, while those with more blood vessels, lymphatic vessels and fat components are softer.

4. Location: fibrous tumors mostly occur in subcutaneous tissues; Adipose-derived tumors mostly occur in the buttocks, lower limbs, and retroperitoneum; Mesothelioma mostly occurs in the thoracic and abdominal cavities; Tumors of smooth muscle origin are more common in the abdominal cavity and trunk. Synovial sarcoma tends to occur near the joints and fascia.

5. Mobility: benign and low-grade malignant tumors, the growth site is often superficial, and the mobility is large. Tumors that grow deeply or infiltrate into surrounding tissues are less mobile. Retroperitoneal tumors are mostly fixed due to anatomical relationships.

6. Temperature: Soft tissue sarcoma has abundant blood supply and vigorous metabolism, and the local temperature can be higher than that of surrounding normal tissues. Benign tumors have a normal local temperature.

7. Regional lymph nodes: soft tissue sarcoma can metastasize along lymphatic channels. Synovial sarcoma and rhabdomyosarcoma often have swollen regional lymph nodes that sometimes coalesce into clumps.

The clinical manifestations of soft tissue tumors are relatively obvious, and it is recommended that you should go to the hospital in time for the above symptoms**, otherwise it will become a soft tissue malignant tumor. Zhang Ming, a TCM oncologist, has 30 years of experience, which can be of great help to cancer patients, so that there is hope in the fight against cancer, and I wish the body a speedy recovery.

Soft tissue tumors are divided into benign and malignant categories, and most patients are malignant tumors, that is, soft tissue sarcomas. There are many types of it, and the common clinical types include: synovial sarcoma, malignant fibrous histiocytoma, liposarcoma, and other types are less common.

Some patients may have no clinical symptoms, such as rapid growth of the mass, with or without bleeding, and need to be alert to the possibility of soft tissue sarcoma. If the tumor is close to blood vessels and nerves, there may be corresponding vascular and neurological symptoms.

As a rare mesenchymal tissue ** tumor, soft tissue sarcoma has a low incidence, what is its clinical manifestation? As a rare tumor type, professional oncology diagnosis and treatment is particularly important.

It is recommended to change hospitals to confirm.

If necessary, surgery is done.

Soft tissue malignancies.

Soft Tissue Malignancy** Method.

I hope to help you better ** soft tissue malignancy.

**Sexual surgery: All tumors must be removed together with the surrounding normal tissue, in order to ensure complete resection, it is often necessary to cut some normal tissue structures, surgical resection should also include the biopsy site, ** and some nearby muscles. For muscle tumors, the affected muscles should be completely removed.

Lymph node dissection is performed only if there is clinical evidence of lymph node involvement. 2.

Debulking surgery: It is a method used for some soft tissue tumors that cannot be completely resected, followed by other non-surgical procedures** after surgery, in order to improve the patient's quality of life and prolong the patient's life. For example, malignant retroperitoneal huge liposarcoma, etc., can be debulking surgery first, and then supplemented with radiation**, which can achieve good results.

3.Amputation: It is suitable for advanced large tumors with ulcers and massive bleeding, and the bleeding cannot be stopped; or accompanied by serious infections, such as sepsis, tetanus, etc., which endanger the patient's life; or the tumor grows rapidly and causes severe pain that is difficult to control with medications; or when there is a pathological fracture of the limb, loss of mobility and other serious conditions, which cannot be saved by other methods, amputation can be considered first.

That's all about soft tissue malignancies.
