What does triple intrathecal chemotherapy prevent?
Intrathecal chemo can both treat certain cancers and stop them from happening. For example, some forms of leukemia and lymphoma are more likely than others to spread to the CSF over time. This could happen for up to half of people with acute lymphoblastic leukemia (ALL).
Why methotrexate is given intrathecal?
Methotrexate is a chemotherapy drug that is used to treat certain types of cancer and leukaemia. When given intrathecally, it prevents leukaemia cells entering the cerebrospinal fluid (CSF) around the spine and brain.
Why is intrathecal chemo given?
Your doctor may recommend intrathecal chemotherapy for two main reasons: to target cancer cells in the space around the brain and spinal cord. to prevent cancer from reaching the CSF from other areas of your body.
What is the difference between epidural and intrathecal?
Intrathecal administration is delivered directly into the CSF and into the superifical spinal cord; epidural administration diffuses through the dura into the CSF, and thus has a slower onset of action.
What is the 5-year survival rate for leukemia?
The 5-year relative survival rate for all types of leukemia is 65 percent, according to the National Cancer Institute (NCI) . Not considering age, new leukemia rates haven’t changed much since 2019.

What drugs are given intrathecally?
Currently there are only three medications approved by the US Food and Drug Administration (FDA) for use via the intrathecal route, ie, morphine, ziconotide, and baclofen. Morphine targets opioid receptors within the dorsal horn.
What drugs are given Intrathecally?
What chemo should never be given intrathecally?
Vinca alkaloids (vinblastine, vinorelbine, vincristine, and vincristine liposomal) are chemotherapy drugs that are intended to be administered intravenously. If given intrathecally, vincristine is nearly always fatal and associated with an irreversible, painful ascending paralysis.
Why is intrathecal route used?
The intrathecal route allows direct drug administration to the CSF by circumventing the blood-brain barrier. It therefore allows delivery of smaller drug doses and the occurrence of side effects is reduced compared with systemic routes of drug administration (eg, oral, intravenous and epidural).
Does intrathecal triple therapy improve survival in acute lymphoblastic leukemia?
Intrathecal triple therapy decreases central nervous system relapse but fails to improve event-free survival when compared with intrathecal methotrexate: results of the Children’s Cancer Group (CCG) 1952 study for standard-risk acute lymphoblastic leukemia, reported by the Children’s Oncology Group
What is triple Intrathecal Therapy for neoplastic cell infiltration in hematology?
Background The administration of triple intrathecal therapy with methotrexate, cytarabine and a corticosteroid for the prophylaxis and treatment of neoplastic cell infiltration in the central nervous system in hematological malignancies is a widespread practice. There is limited information availabl …
Intrathecal chemotherapy is a form of cancer treatment in which a healthcare professional injects chemotherapy drugs into the cerebrospinal fluid (CSF). This colorless fluid surrounds the brain and spinal cord, which form the central nervous system (CNS), to protect them from injuries.
How many doses of intrathecal therapy are given to newly diagnosed hr b-all?
Newly diagnosed children with HR B-ALL were randomized post-Induction in a 1:1 fashion to receive ITT versus IT MTX. A total of 21-26 doses of post-Induction intrathecal therapy was administered during Consolidation (n=4), Interim Maintenance (n=2), Delayed Intensification (n=3), and Maintenance (n=12 for girls, n=16 for boys).
