Abstract:
A 10-year-old child presented with small-cell osteosarcoma of the proximal end of the tibia. Pulmonary metastases appeared after a gap of 9 months of ablative surgery, as did late multiple extra-pulmonary skeletal metastases, including the hand and foot bones after 6 months of pulmonary metastases. These late extrapulmonary metastases appear to be secondary to pulmonary metastases.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
