Advances in blood cancer treatment

Thousands of studies on leukemia, also known as leukemia, have been conducted, providing positive results in treatment. Treatments are prescribed by a doctor for a patient based on many factors, including the type of disease and the stage of the disease.

"Smart" drugs

For a long time, cancer drugs were not used in the past because they attack both healthy and cancerous cells. Currently, cancer drugs are "smarter". They only attack cancer cells without destroying other healthy cells.

People with chronic myelogenous blood cancer (CML) can take these drugs. In the past, CML was a life-threatening disease. Current drugs can block abnormal proteins produced by mutations in the CML chromosome.

Immunotherapy with definite targets

Researchers are testing immunotherapy with a definite goal to treat certain types of white blood cells. Using this method, the immune system finds and destroys cells that carry abnormal genes, capable of causing disease. This measure protects healthy cells from chemotherapy.

Acute cytostatic leukemia (ALL) is extremely dangerous. Your doctor will use immunotherapy with a defined goal when treating an adult. Therapy is still in a clinical trial phase but offers hope for patients with ALL.

New chemotherapy drugs

Chemotherapy is used to treat many types of cancer, including white blood cells. The new chemotherapy drugs have the ability to better identify and destroy blood cancer cells. The drugs currently tested for patients with acute myeloid leukemia (AML) include tipifarnib, bortezomib, sapacitabine and laromustine.

Stem cell transplantation

Most chemotherapy drugs kill both cancerous and healthy cells. High doses of chemotherapy drugs can also destroy bone marrow cells, preventing the production of new, healthy blood cells.

To solve this problem, another treatment is stem cell transplantation. The doctor will insert healthy stem cells from the donor into the body of the person with leukemia. Bone marrow cells then produce healthy blood cells. Nowadays, cancer patients requiring high-dose chemotherapy often combine chemotherapy and stem cell transplantation.

Biological therapy

Also known as immunotherapy, biological therapy helps the immune system establish defense mechanisms and fight leukemia cells. The method has fewer side effects than other treatments. Biological therapy được sử dụng độc lập, kết hợp với hoá trị hoặc sử dụng sau các liệu pháp khác.

Clinical trials

The clinical trials studied different drugs and therapies. Combinations of therapies are still being carried out across many stages of leukemia. Tests are done in people newly diagnosed and in people who have had the disease for many years. Several tests lead to the latest treatment.
