Abstract

Secondary or therapy related myelodysplastic syndrome may develop following treatment with alkylating agents and radiotherapy. The condition may also follow high dose therapy for malignant lymphomas. We describe two patients who developed secondary myelodysplasia. The first is a 76-year old female with a low grade lymphoma who developed pancytopenia with monosomy 7. Secondary myelodysplasia was diagnosed 24 months after treatment with chlorambucil (total dose of 900 mg) and 12 months after treatment with trophosphamide (total dose of 24 g). The second patient was a 48-year old male who underwent autologous bone marrow transplantation for a relapsed low grade lymphoma. Following autografting he had persistent anemia and trombocytopenia. Secondary myelodysplastic syndrome with complex karyotype was diagnosed 54 months after high dose therapy. He died nine months later of bone marrow failure.

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
