Introduction
In general, there is no fixed standard for the duration of chemotherapy in acute leukemia, as it primarily depends on the disease subtype, patient's age, response to treatment, and overall physical condition. The treatment course usually lasts from 1 month to 5 years. During therapy, regular follow-up tests such as complete blood counts and bone marrow aspiration are required. Treatment plans should be dynamically adjusted based on these results to ensure therapeutic efficacy while minimizing the risk of adverse effects.
In general, there is no fixed standard for the duration of chemotherapy for acute leukemia. It mainly depends on the type of disease, patient's age, treatment response, and overall physical condition, typically ranging from 1 month to 5 years. The specific analysis is as follows:
From the perspective of disease type, the chemotherapy course for acute lymphoblastic leukemia (ALL) is relatively longer. Pediatric patients generally require 2–3 years, while adult patients may need an extended period of 3–5 years, divided into three phases: induction remission, consolidation/intensification, and maintenance therapy. In contrast, the chemotherapy course for acute myeloid leukemia (AML) is shorter. The induction remission phase usually lasts 1–2 months, followed by 4–6 cycles of consolidation therapy. Some patients do not require maintenance therapy, resulting in a total treatment duration of approximately 6–12 months.
A patient’s response to treatment also affects the length of chemotherapy. If the condition achieves rapid and sustained remission after treatment, the standard treatment course may be completed as planned. However, if relapse occurs or remission is incomplete, the treatment plan may need adjustment, including prolonging chemotherapy duration or changing medications.
Regular follow-up tests such as complete blood counts and bone marrow aspiration are required during treatment. Treatment plans should be dynamically adjusted based on test results to ensure therapeutic efficacy while minimizing the risk of adverse effects.
