The exact cause and mechanism of desmoplastic small round cell tumors formation, is unknown.
It is associated with a unique chromosomal translocation t(11;22) (p13:q12) resulting in an EWS/WT1 transcript that is diagnostic of this tumor. This transcript codes for a protein that acts as a transcriptional activator that fails to suppress tumor growth.
4 Making A Diagnosis
Tests and procedures that are used to diagnose desmoplatic small round cell tumors include:
Treatments of desmoplastic small round cell tumors include:
Surgery in which doctors remove all the cancerous tissue. Surgery is only used in cases where the tumor hasn't spread to surrounding tissue.
Chemotherapy-in this treatment method, medications are used to kill cancer cells. It is usually used before surgery to shrink the tumor and after surgery to kill the remaining cancer cells that might be left after surgery.
Radiation therapy- uses powerful energy beams, such as X-rays to kill cancer cells. It is mostly used after surgery to kill the remaining cancer cells.
Stem cell transplant to replace bone marrow with bone marrow stem cells. High dose chemotherapy is given before the stem cell infusion.
