Lymphoma Diagnosis and Treatment

Lymphoma encompasses more than 60 distinct cancers of the lymphatic system, each arising from different stages of immune cell development and carrying its own genetic signature, clinical behavior, and prognosis. Pathologists and oncologists work together to classify these malignancies with increasing molecular precision — using gene expression profiling, B-cell receptor signaling analysis, and PET imaging — because the right diagnosis directly determines whether a patient receives, say, rituximab-based chemotherapy or a more aggressive regimen. Advances in understanding the genetic pathogenesis of subtypes like diffuse large B-cell lymphoma and mantle cell lymphoma have already produced targeted therapies that outperform older treatments, yet predicting which patients will relapse or develop resistance remains an unsolved problem. Current research is pushing toward finer molecular stratification of tumors and earlier, more reliable biomarkers that can guide treatment decisions before a patient's disease progresses.
