DefinitionThis section has been translated automatically.

Medical term for the presence of large tumour masses (= Bulky Disease or Bulk). Bulk is usually defined as lymphoma masses with a diameter of more than 7.5 cm before the start of therapy. For certain lymphomas (e.g. diffuse large B-cell lymphoma), a very large lymphoma manifestation is a risk factor independent of the International Prognostic Index (Pfreundschuh M et al. 2008).

Note(s)This section has been translated automatically.

The common definition of a 'bulk' in Germany is a diameter ≥7.5 cm. In some countries a diameter ≥10 cm is required
