Therapy related myelodysplasia/myeloproliferative neoplasia-unclassified with acute leukemic transformation following Paclitaxel and Carboplatin based chemotherapy in an ovarian cancer patient.

Alkylating agents used in chemotherapy are mutagenic and have strong leukemogenic potential. The most serious long term complication of chemotherapy is the development of secondary disease, particularly hematological malignancy; they have rarely been reported in the context of ovarian cancer treatment. We describe quite a rare occurrence of a myelodyplastic/myeloproliferative neoplasm, unclassified (MDS/MPN-U) with acute leukemic transformation and multiple cytogenetic abnormalities not usually found together as JAK2 V617F mutation, 5q- and 7q-deletion, after exposure to paclitaxel and carboplatin based chemotherapy in a patient treated for ovarian cancer. We should be aware of such complication whose prognosis is really poor.
