Soft tissue sarcoma
Soft tissue sarcomas are a group of malignant tumors originating from muscle, fat, blood vessels, nerves, or connective tissues. They are classified as rare cancers but exhibit high heterogeneity and local invasiveness. These tumors can arise in the extremities, trunk, head and neck, or around visceral organs, and may invade surrounding tissues or lymph nodes. Some subtypes are prone to distant metastasis. Major risk factors include:
• Genetic and familial factors – a history of hereditary syndromes, such as Li-Fraumeni syndrome, can increase susceptibility.
• Chronic injury or inflammation – repeated trauma or sites of chronic inflammation may elevate the risk of developing sarcomas.
• Radiation exposure – patients with prior local radiotherapy have an increased risk of developing soft tissue sarcomas.
• Immunodeficiency – organ transplant recipients or individuals on long-term immunosuppressive therapy are more susceptible.
Because early stages often present with no obvious symptoms, soft tissue sarcomas are frequently detected only when tumor size increases or function is affected. Early screening and nursing interventions are therefore critical for maintaining quality of life and supporting recovery.
Early symptoms of soft tissue sarcomas are often non-specific. As the tumor progresses, the following may occur:
• Mass or nodule – the most common presentation, usually painless, located in the deep tissues of the extremities or trunk.
• Local swelling or tenderness – may develop as the tumor enlarges, potentially affecting surrounding tissues and nerves.
• Functional impairment – such as limitations in limb movement or sensory abnormalities, indicating deep tissue invasion.
• Skin changes – superficial skin may show erythema, warmth, or ulceration in later stages.
• Systemic symptoms – including weight loss, fatigue, or low-grade fever, suggesting disease progression or metastasis.
Timely evaluation of mass lesions, early imaging studies, and appropriate nursing management are essential for controlling tumor progression.
The diagnostic approaches for soft tissue sarcomas are diverse, aiming for early detection, subtype classification, and the development of personalized care plans:
• Clinical examination – assessment of mass size, consistency, mobility, and tenderness.
• Imaging studies
– MRI: the preferred modality, used to evaluate tumor extent, depth, and relationship with surrounding tissues.
– CT: particularly useful for assessing tumors in the trunk or near visceral organs.
– PET-CT: used to detect distant metastases and assess systemic disease involvement.
• Pathological examination – biopsy for definitive diagnosis, determining sarcoma subtype, differentiation grade, and invasiveness.
• Molecular and genetic testing – indicated for high-risk or recurrent patients to identify molecular markers and guide personalized care strategies.
Care and supportive strategies for soft tissue sarcomas can be divided into traditional methods and personalized supportive strategies, aiming to slow disease progression, preserve limb function, and improve quality of life:
• Surgery
– Local excision is the preferred approach, aiming for complete tumor removal with necessary surgical margins. For deep-seated limb tumors, functional reconstruction may be required.
– Postoperative care – including wound management, rehabilitation training, and nutritional support – can promote recovery and maintain limb function.
• Radiation and Chemotherapy Care
– Radiation therapy may be used as adjuvant treatment post-surgery or for local control of advanced tumors.
– Chemotherapy is indicated for patients at high risk of recurrence or with metastasis. Coupled with nutritional management and fluid balance monitoring, it can reduce side effects and preserve physiological function.
• Targeted and Immune Support
– Personalized supportive plans are developed based on molecular testing results, targeting specific signaling pathways or immune modulation.
– Combined with immune enhancement, nutritional support, and rehabilitation interventions, these strategies can strengthen immunity and improve quality of life.
• Nutritional and Supportive Therapies
– Intravenous supplementation with high-dose vitamin C, glutathione, amino acids, and trace elements may enhance energy levels, support immune function, and promote wound healing.
– Dietary recommendations include protein-rich and antioxidant-rich foods to maintain muscle mass and overall health.
• Personalized Monitoring and Care
– Regular imaging, blood tests, and molecular marker assessments to monitor tumor progression and recurrence risk.
– Development of individualized care plans to adjust nutrition, lifestyle, and psychological support.
– Specialized care programs for patients with high recurrence risk or functional impairment help enhance long-term quality of life.
