Brief Summary

There are two regions in the adult brain that exhibit neuronal stem and progenitor cells, generating new neurons postnatally and throughout adulthood. One is the so called subventricular zone the other is the dentate gyrus of the hippocampus. Adult neurogenesis is a physiological process representing an important functional impact for certain brain areas, especially the hippocampus. The hippocampal formation plays an important role in long-term memory and spatial navigation. Inhibition of adult neurogenesis in mice by chemotherapy or radiation is followed by significant deficits in hippocampal memory functions while hippocampus-independent memory is unaffected. Clinical trials had shown that chemotherapy and brain radiation lead to cognitive dysfunction. However, the exact mechanisms underlying this phenomenon are still unidentified. The aim of our study is to investigate, whether the inhibition of adult neural stem cell proliferation in the hippocampus by intrathecal chemotherapy and/or cerebral radiation is responsible for treatment induced memory deficits. We will investigate patients suffering from acute lymphatic leukaemia (ALL) that receive prophylactic intrathecal chemotherapy and brain irradiation. The study represents a longitudinal investigation including a virtual "humanized" version of the morris-water-maze to test hippocampus dependent spatial memory, as well as MR-imaging for morphological (volumetry) and biochemical (spectroscopy) data.

Outcome Measures

Primary Outcomes (6)

  • Hippocampal function measured with virtual water maze test

    The hippocampal function will by studies in a longitudinal manner and thus we plan to measure the water maze test performance at several time points (time frames) of the study.

  • Hippocampal function measured with virtual water maze test

    The hippocampal function will by studies in a longitudinal manner and thus we plan to measure the water maze test performance at several time points (time frames) of the study.

    day 9

  • Hippocampal function measured with virtual water maze test

    The hippocampal function will by studies in a longitudinal manner and thus we plan to measure the water maze test performance at several time points (time frames) of the study.

    day 16

  • Hippocampal function measured with virtual water maze test

    The hippocampal function will by studies in a longitudinal manner and thus we plan to measure the water maze test performance at several time points (time frames) of the study.

    day 52

  • Hippocampal function measured with virtual water maze test

    The hippocampal function will by studies in a longitudinal manner and thus we plan to measure the water maze test performance at several time points (time frames) of the study.

Study Arms (1)

Patient with ALL under chemotherapy

This group consists of patients with initial diagnosis of acute lymphatic leukemia (ALL), who are enrolled into the GMALL 2003 chemotherapy study. There is no change of the initial GMALL 2003 treatment protocol for the present study.

Eligibility Criteria

Age18 Years - 40 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Consecutive patients of the Department of Internal Medicine at the Dresden University of Technology hospital, who are initially diagnosed of acute lymphatic leukemia (ALL) and included into the GMALL 2003 chemotherapy study. All treatment procedures and outcome measurements of the GMALL 2003 study (most importantly also the safety outcome measures) are regularly performed in the sub population of the present sub study. Inclusion and exclusion criteria are given below.

You may qualify if:

  • Initial diagnosis of acute lymphatic leukaemia (ALL)
  • Treatment within the German Multicenter Adult ALL (GMALL 2003) therapy study
  • Age 18 to 40 years
  • Eligibility for performing study procedure
  • Informed consent

You may not qualify if:

  • Neuropsychiatric disorders
  • Present contraindication for MRI investigation (e.g. pacemaker)
