Soft Tissue Sarcoma Treatment

Soft tissue sarcomas encompass a variety of benign and malignant tumors, commonly occurring in muscles, fat, blood vessels, and other tissues, mainly affecting young, middle-aged, and elderly populations. Prognosis varies widely among subtypes, and treatment strategies should be individualized. If treatment is delayed, tumors may expand locally or metastasize distantly, severely affecting function and survival. Currently, multidisciplinary comprehensive treatment is the main approach.

Emerging Treatment Methods

Immune Reconstruction Cell Therapy

Immune reconstruction cell therapy in soft tissue sarcoma focuses on rebuilding the patient’s anti-tumor immune system. By extracting immune cells, activating and expanding them in the laboratory, and reinfusing them back, it enhances the ability to recognize and kill tumor cells. It is suitable for postoperative recurrence prevention, patients with metastasis, and those resistant to radiotherapy or chemotherapy. This therapy can be combined with surgery and chemotherapy to enhance comprehensive outcomes.

① Improves postoperative control rate and effectively reduces recurrence risk

② Delays progression in advanced and recurrent patients

③ Mild side effects, suitable for patients with weak physical condition

④ Can be applied simultaneously with traditional treatments to enhance overall therapeutic response

In practice, patients undergoing surgery, radiotherapy, or chemotherapy often face immune dysfunction, increased infection risk, and slow recovery. To help patients better tolerate treatment and improve survival quality, phased immune reconstruction programs must be scientifically designed for different cycles.

● Short-term plan: Rapidly enhance immunity through immune cell reinfusion to strengthen anti-tumor effects.

● Mid-term plan: Reduce side effects of conventional treatments, promote recovery, and ensure completion of standardized therapy.

● Long-term plan: Comprehensive enhancement of immunity through immune cell reconstruction, gut immunity restoration, elemental immunity rebuilding, and immune nutrition support, thereby improving quality of life and prolonging survival.

Conventional Treatment Methods

1. Surgical Resection as the Foundation

Surgical resection is the first-line option for soft tissue sarcoma treatment. The goal is complete tumor removal with clean margins. For well-defined, low-grade tumors, simple excision achieves good results. For high-grade or infiltrative lesions, wider margins or reconstructive surgery are often required.

2. Intraoperative Navigation and Cryo-assisted Resection

Modern techniques such as intraoperative navigation and cryo-assisted resection play an important role. Navigation systems help precisely define tumor boundaries, avoiding over- or under-resection. Cryoablation is effective in handling tumor margins, especially for poorly defined regions.

3. Radiotherapy for Local Control

Radiotherapy is suitable for high-risk postoperative patients or those unfit for surgery. Preoperative radiotherapy can shrink lesions, while postoperative radiotherapy helps control residual cells. Modern intensity-modulated radiotherapy (IMRT) improves targeting accuracy and reduces damage to normal tissues.

4. Chemotherapy for Certain High-grade Tumors

Chemotherapy is used for certain high-grade sarcomas (such as synovial sarcoma and undifferentiated pleomorphic sarcoma). Common drugs include doxorubicin and ifosfamide. Chemotherapy is effective in reducing tumor size and controlling metastasis but requires close monitoring for side effects.

5. Targeted Therapy and Molecular Inhibitors

Some soft tissue sarcomas present clear molecular abnormalities such as PDGFR and ALK. Targeted drugs can block relevant pathways and interfere with tumor growth mechanisms. Drugs such as pazopanib and apatinib are gradually being applied clinically, providing new options for advanced or recurrent cases.

6. Minimally Invasive Interventions and Thermal Ablation

For some localized or inoperable cases, minimally invasive treatments such as radiofrequency ablation, microwave ablation, and cryoablation are applied. These approaches cause minimal trauma, allow rapid recovery, and can be precisely guided by imaging, making them suitable for elderly patients or those with comorbidities.

7. Combined Treatment Models Becoming Mainstream

An increasing number of patients receive individualized combination therapy, such as preoperative radiotherapy plus postoperative cellular immunotherapy and chemotherapy. Multidisciplinary collaboration improves local control, extends progression-free survival, and balances functional preservation with quality of life.

Conclusion

Treatment of soft tissue sarcoma requires integration of surgery, cellular therapy, and minimally invasive methods to formulate individualized strategies. Experts at United Life International Medical Center emphasize that early intervention and multimodal treatment are key to improving efficacy and ensuring better quality of life for patients.
