Documented meningeal lymphomatosis (spread to the brain or spinal cord membranes).
It was designed to offer better accuracy than traditional metrics by combining cellular biomarkers with imaging data and physical disease characteristics. The Components of KBMP4
High proliferation index (Ki67 ≥ 70%) on immunohistochemistry. B (Bulky): Physical presence of a tumor mass ≥ 7.5 cm. Documented meningeal lymphomatosis (spread to the brain or
💡 The inclusion of the P4 (Interim PET) parameter is significant because it allows doctors to adjust treatment mid-course based on how the tumor is actually responding to chemotherapy. Clinical Significance
While the International Prognostic Index (IPI) is the standard, KBMP4 provides a more granular look at aggressive "Double-Hit" or "Double-Expression" lymphomas. B (Bulky): Physical presence of a tumor mass ≥ 7
Research indicates that variables like bulky disease and Ki67 are strong independent predictors of how long a patient will remain in remission.
High KBMP4 scores often signal that standard R-CHOP therapy may not be enough, potentially leading to more intensive consolidative strategies or clinical trials. Research indicates that variables like bulky disease and
If you are looking for or comparisons to other models like the IPI or NCCN-IPI , I can provide those details.
