Plain English summary of protocol
Background and study aims:
Leukaemia is a cancer of the white blood cells. Acute myeloid leukaemia (AML) is an aggressive cancer of the myeloid cells, white blood cells that perform a variety of functions, including fighting bacterial infections and parasites. It progresses rapidly and needs immediate treatment. The prognosis for someone with AML is usually poor, as the chemotherapy used is often insufficient to successfully treat the condition. Decitabine is one of a new class of chemotherapy drugs called DNA demethylating agents. DNA methylation is a major mechanism that regulates gene expression in cells and an increase in DNA methylation can block the activity of tumour suppressor genes that control cell division and growth. Blocking the activity of these suppressor genes can result in cell division that is not controlled, which in turn, can lead to cancer. Decitabine works in two ways. It interferes with DNA methylation (demethylating), which causes the tumour suppressor genes to become active again and restore control over cell division and growth. Decitabine is also very toxic to rapidly dividing cancer cells, causing cell death. Here, we want to see if decitabine assisted chemotherapy could be an effective treatment for AML.
Who can participate?
Any AML patients (except acute promyelocytic leukaemia (APL) patients) of any age that have relapsed, or are considered at risk of relapse.
What does the study involve?
Participants are treated with decitabine combined with chemotherapeutic drugs (anthracycline, cytarabine, etc.). Each patient is treated for a maximum of 5 years and they are followed up once every 3 months until their death or after a further period of 5 years.
What are the possible benefits and risks of participating?
There are great benefits expected for patients who receive decitabine assisted chemotherapy in terms of being treated for AML. The main risks are bleeding and flu like symptoms. This can be prevented by reducing the dose given and using alternative drugs during the treatment schedule.

| Scientific title | Perspective study on an effective treatment for acute myeloid leukemia with decitabine and chemotherapy |
| Study objectives | It was hypothesized that decitabine with low-dose chemotherapy function synergistically. Thereby together they could improve the clinical outcome of acute myeloid leukemia (AML) patients (except acute promyelocytic leukemia [APL]) during the treatment. |
| Ethics approval(s) | Harbin Medical University Ethics Committee, 12/12/2006, ref: HM070110. |
| Health condition(s) or problem(s) studied | Acute myeloid leukemia (AML) |
| Intervention | The study involved AML patients (except APL patients) from different Hematology departments in different hospitals at Heilongjiang Province in China. All the treatment centers follow the same treatment protocol and evaluation standards. Treatment methods: AML patients who give written consent to accept the treatment protocols are enrolled. For remission induction, each cycle of treatment includes cytarabine 100 mg/m2 for 7 days, anthrocycline 15 mg/m2 for another 3 days, decitabine 10-15 mg/m2 once every 2 days. Five treatment cycles are repeated with 2-week intervals after the first cycle. For maintenance treatment, treatment is repeated once every three months. Blood and bone marrow cell study, biopsy, and cytogenetics are tested once every 3 months. The total duration of treatment is 5 years, and follow-up for all treatment arms is from diagnosis, then once every 3 months, until death or 5 years and beyond. |
