Sarcomas are extremely heterogeneous group of rare solid tumors of mesenchymal cell origin with distinct clinical and pathohistological characteristics. We divide them into two categories: soft tissue sarcomas and bone sarcomas. Malignant tumors or sarcomas of the soft tissue account for less than 1% of all malignomas in adults and approximately 15% of all malignant tumors in childhood. They most commonly appear on the limbs (upper 30%, lower 10%), then intraabdominally (20% visceral organs, 15% retroperitoneally), on the trunk 10%, on the head and neck 10%. Bone tumors are even rarer and make up only 0,2% of all malignomas. Osteosarcoma occurs most frequently (35% of all tumors), chondrosarcoma (30%), Ewing's sarcoma (15%) and giant-cell tumor (GCT). Soft tissue tumors occur as a painless mass that can be present for weeks or months. Pain or edema depend on pressure or infiltration of the adjacent organs and structures. Weakness, weight loss and anemia usually indicate metastatic disease. Symptoms of bone tumors are pain and edema. It is specific that the pain occurs before edema and intensifies at night. Aggressive tumors may have general symptoms such as weight loss, fever, weakness and anemia. Sarcomas are treated surgically, via radiotherapy or chemotherapy. The treatment, other than desired effects, also has some side effects, so nurses play an important role in patient care. Caring for an oncology patient is extremely demanding and nurses have to be educated. Besides their role in the care for the patient who is in active treatment, nurses often take care of the one that requires palliative care.
