What is undifferentiated cancer?

Undifferentiated cancer: A cancer in which the cells are very immature and “primitive” and do not look like cells in the tissue from it arose. As a rule, an undifferentiated cancer is more malignant than a cancer of that type which is well differentiated. Undifferentiated cells are said to be anaplastic.

How fast does plasmacytoma grow?

Solitary bone plasmacytoma (SBP) progresses to multiple myeloma at a rate of 65-84% at 10 years and 65-100% at 15 years. The median onset of conversion to multiple myeloma is 2-5 years with a 10-year disease-free survival rate of 15-46%.
