Chemotherapy in a patient with prior history of idiopathic thrombocytopenic purpura

We described a 67 years old small-cell lung cancer patient with a prior history of idiopathic thrombocytopenic purpura (ITP) who was treated with successful chemotherapy. It is probably safe to administer chemotherapeutic agents for some cancer patients with prior history of ITP, but it is important to prevent or minimize the toxicities of these chemotherapeutic agents.
