Bone metastasis after chemotherapy of lung cancer?

There was no clinical symptom in the early stage of bone metastasis, but pain in the late stage. It often takes more than one year from bone metastasis to clinical pain. Therefore, patients with lung cancer can not exclude bone metastasis because of no pain symptoms and refuse clinical examination.

Carcinomatous bone pain is characterized by fixed position and gradual aggravation of pain, which is more obvious at night than during the day; Thoracic vertebrae metastasis can produce banded pain; Lumbar metastasis often occurs along the lateral side of the lower extremities to the lateral side of the foot radiation pain, with cough, defecation and other activities aggravated. Sciatica similar to hyperosteogeny or intervertebral disc prolapse should be paid attention to.

The most commonly used clinical examination is isotope bone scan, which can quickly show the bone metastasis of the whole body with high sensitivity but low specificity; MRI and CT can show the local situation of bone metastasis, so the specificity and local location are better than bone scan,
