Dacarbazine (da-KAR-ba-zeen) (brand names DTIC, DTIC-Dome; also known as DIC or Imidazole Carboxamide) is an antineoplastic chemotherapy drug used in the treatment of various cancers, among them malignant melanoma and Hodgkin lymphoma. Antineoplastic drugs are drugs which interfere with cell growth and impede the formation of new tissue - in this case, tumor tissue. These drugs are also known as cytotoxic drugs.
