The Department of Hematology and Oncology is responsible for the diagnosis and treatment of cancer (solid tumors) and blood diseases. The medical field includes solid tumors (e.g., gastric cancer, lung cancer, breast cancer, uterine cancer, colon cancer, ovarian cancer, and head and neck cancer), blood cancers (e.g., leukemia, malignant lymphoma, and multiple myeloma), and blood diseases (e.g., anemia and platelet disease).

In the case of solid tumors, the treatment plan may vary according to the cancer progression. The Department of Hematology and Oncology determines the most appropriate treatment method for the cancer patient based on the latest information about cancer. 

Chemotherapy refers to the treatment of cancer with medications. It is added before and after surgery or radiation therapy. Recently, two to three treatments are combined for a higher success rate.

For an effective diagnosis and surgical treatment of cancer, radiation therapy and chemotherapy should be selected and combined based on the degree of cancer progression and type of cancer. It is a complex disease that requires a great deal of cooperation from cancer centers and consultation clinics. 

The Department of Hematology and Oncology at KUMC plays an important role in cancer consultation. It has a close consultation system with the Department of Laboratory Medicine, Department of Pathology, and Department of Gastroenterology in addition to the operation of a clinic, in which the multidisciplinary system is established with the Department of Surgery, Department of Thoracic Surgery, Department of Urology, Department of OB/GYN, and Department of Radiation Oncology for treatment. 

In contrast to the solid tumors mentioned above, blood cancer without surgery or radiation therapy is only subject to chemotherapy due to the nature of the disease. High-dose chemotherapy is usually performed for such cases, as opposed to hematopoietic stem cell transplantation, which is a special treatment field. The recent launching of the hematopoietic stem cell transplantation center has given patients hope of cure, with the active utilization of autologous hematopoietic stem cell transplantation, allogeneic hematopoietic stem cell transplantation, and hematopoietic stem cell transplantation using umbilical cord blood. The broad range of bone marrow transplantation and hematopoietic stem cell transplantation treatment includes leukemia, aplastic anemia, malignant lymphoma, multiple myeloma, and myelodysplastic syndrome. In the fight against pathogens, it is deemed necessary to provide a sterile environment for patients with blood cancer. The Department of Hematology and Oncology at KUMC is equipped with a sterile room and a quasi-sterile room. We are constantly improving the quality of medical treatment in collaboration with the Department of Infectious Medicine.
