Q

What is the most common cause of bone tumors in older adults?

Study These Flashcards
A

Metastatic disease

25
What organs are commonly the primary sources of metastases?
Lung, Breast, Prostate, Kidney
26
What are the symptoms of metastatic disease?
Pain that is worse at night, Possible nerve pain or complaints, Unintentional weight loss, Unexplained fatigue, Fever/night sweats, Malaise, Lymphadenopathy, Evidence of hypercalcemia, Reduced muscle tone, Diminished deep tendon reflexes
27
What diagnostics will be performed if there is concern for metastatic bone disease?
Calcium-Elevated, Alkaline phosphatase-Elevated (could be d/t liver or bone), Initially radiographs, CT, if spine order MRI, Biopsy-definitive diagnosis
28
What is the treatment for metastatic bone disease?
Bisphosphonates (Note: consider calcium and vitamin D supplementation, and requires renal clearance), Monoclonal antibodies, Radiation, Ablation
29
What is the age distribution of osteosarcoma?
Children ages 13-18, Older adults ages 80-84
30
What are the risk factors of developing osteosarcoma?
Radiation, Chemo, Pagets disease, Retinoblastoma, Li-Fraumeni syndrome (turns off TP53 tumor suppressor gene)
31
What areas are most commonly affected in osteosarcoma?
Distal femur, Proximal tibia, Proximal humerus
32
What will be found on physical exam for osteosarcoma?
Large tender soft tissue mass, Limping, Decreased ROM, Regional lymphadenopathy
33
What diagnostics will be used for osteosarcoma?
Lactate Dehydrogenase (LDH), Alkaline Phosphatase (ALP), X-Ray-sunburst appearance, codmans triangle, MRI of the entire bone, Chest CT to check for metastases, Biopsy-definitive diagnosis
34
What are the treatment options for osteosarcoma?
Wide excision/limb sparing, +/- chemotherapy, +/- radiation, Possibly amputation

Long bones of the leg, pelvis, shoulder blade
38
What are the physical exam findings of osteochondromas?
Painless, palpable lump, May cause neurovascular changes
39
What diagnostics are used for osteochondroma?
X-ray: cartilage cap, typically grows near the growth plate and away from it, Additional imaging for other complications CT vs MRI
40
What is an osteoid osteoma?
Benign bone tumor that has prostaglandins. night pain relieved with NSAID’s, and swelling
41
What is an osteoblastoma?
Benign bone tumor that lacks prostaglandins and is more vascularized. Characterized by dull, localized pain with little relief from NSAIDs
42
How are osteoid osteomas treated?
Conservatively with NSAIDS, surgical excision; CT guided RF ablation
43

Surgical excision, sclerotherapy, embolization of the vessel, denosumab
44
What is the most common type of bone cyst?
Simple/unicamerial bone cyst
45
What is a fibrous lesion and how is it caused?
Benign bone lesion caused by proliferation of fibrous tissue d/t missense mutation on the GNAS 1 gene on chromosome 20.
