Bone Tumors Flashcards
tumors derived from connective tissue, such as bone, cartilage, muscle, blood vessels, or lymphoid tissue are termed as
Sarcomas
Bone tumors may arise during adolescence because
rapid bone growth is occuring at this time.
The two most frequently occurring types of bone tumors are
*Osteosarcoma
*Ewing sarcoma
is a malignant tumor of long bone involving rapid growing bone tissue
Osteosarcoma
The osteosarcoma is associated with what s/x?
locoregional pain and swelling
Most common sites of occurrence for Osteosarcoma are?
*distal femur
*proximal tibia
*proximal humerus
Features of osteosarcoma are visible on
radiologic studies such as radiograph or an MRI
is prescribed to shrink the tumor prior to surgical resection for osteosarcoma
Chemotherapy
A common chemotherapy medication regimen used for treatment of osteosarcoma includes
*methotrexate
*cisplatin
*doxorubicin
*cyclophosphamide
*ifosfamide
what do you call procedures that attempt to remove the tumor without amuputation
“Limb Salvage Procedures”
bone that is removed is typically replaced by a
cadaver or prosthesis
is a malignant connective tissue tumor; it occurs most frequently in the bone marrow of the diaphyseal are of long bones
Ewing Sarcoma
Ewing Sarcoma may also present as a primary site outside the skeletal system where it is referred to as
Primitive Neuroectodermal Tumor (PNET)
Metastasis of Ewing Sarcoma has common sites of
*lungs
*CNS
*lymph nodes
Radiographs for Ewing Sarcoma will reveal an unusual _______ reaction surrounding the invading tumor cells.
