Study summary

A prospective imaging and translational tissue study in CNS lymphoma to enable further disease characterisation and the development of potential predictive and prognostic biomarkers.

Read the detailed description

As a single centre exploratory study, this trial will recruit patients with newly diagnosed primary CNS lymphoma and will look at the molecular aspects of the disease in the tissue collection and imaging response assessments using CCA with respect to progression free survival.

Study population

Patients with newly diagnosed primary CNS lymphoma

Inclusion criteria

  • Subjects capable of giving informed consent, or if appropriate, if subject's capacity is deemed limited due to CNS involvement, a consultee can provide consent on their behalf. Some patients with PCNSL may be incapable of providing their own consent due to the neurological effects of their disease. In these cases the patient will be classed as an incapacitated adult and a legal representative will be sought in accordance with English or Scottish law as applicable (see 7.2.1)
  • A radiological or histological diagnosis of primary CNS lymphoma.
  • Have not received prior CNS directed therapy. Prior use of steroids is permitted.
  • Participants aged ≥18 years old.

Exclusion criteria

Exclusion Criteria:

  • Involvement of lymphoma outside of the CNS

What researchers measure

Primary outcomes

  1. Plasma ctDNA detection

    To assess if plasma ctDNA detection measured from end of treatment (using the tumour informed approach) can be used an early detection tool for progressive disease.

    Time frame: 5 Years

  2. Contrast clearance analysis

    To assess the results of contrast clearance analysis

    Time frame: 5 Years

Secondary outcomes

  1. Plasma ctDNA detection from end of treatment

    To assess if plasma ctDNA detection measured from end of treatment (using the tumour agnostic approach) can be used as an early detection tool for progressive disease

    Time frame: 5 Years

  2. Plasma ctDNA detection rate at baseline

    To assess plasma ctDNA detection rate at baseline using the (i) tumour agnostic and (ii) tumour informed approach

    Time frame: 5 Years

  3. Plasma ctDNA detection at end of treatment

    To assess whether plasma ctDNA detection at end of treatment can be used an early detection tool for progressive disease and survival using the (i) tumour agnostic and (ii) tumour informed approach

    Time frame: 5 Years

  4. Plasma ctDNA detection rate at disease progression

    To assess plasma ctDNA detection rate at disease progression using the (i) tumour agnostic and (ii) tumour informed approach

    Time frame: 5 Years

  5. Radiological data provided by CCA

    To evaluate whether additional radiological data provided by CCA is useful for prognostication and is associated with disease progression and survival

    Time frame: 5 Years
