Lymphoma

Lymphoma

Lymphoma is a cancer of the lymphatic system, which is part of the body's germ-fighting immune network. It starts in white blood cells called lymphocytes. Unlike leukemia, which is primarily in the blood and bone marrow, lymphoma often begins in the lymph nodes, spleen, thymus, or tonsils.

When You Should Consider Lymphoma Evaluation

• Painless swelling of lymph nodes in the neck, armpit, or groin.

• Drenching night sweats.

• Unexplained fever.

• Sudden weight loss (more than 10% of body weight).

• Persistent fatigue or itchy skin.

Methods of Lymphoma Classification

• Hodgkin Lymphoma (HL): Characterized by the presence of giant Reed-Sternberg cells; often follows a predictable path through the lymph nodes.

• Non-Hodgkin Lymphoma (NHL): A diverse group further divided into B-cell (85%) and T-cell lymphomas.

• Indolent (Slow-growing): Types such as Follicular Lymphoma where patients may live for years with minimal symptoms.

• Aggressive (Fast-growing): Types such as Diffuse Large B-cell Lymphoma that require immediate, intensive treatment.

How Lymphoma Is Managed

• Chemotherapy: The primary treatment backbone for most aggressive forms of the disease.

• Radiation Therapy: Used to target specific areas of bulky disease.

• Immunotherapy: Utilizing drugs like Rituximab to help the immune system identify and kill B-cells.

• Targeted Therapy: Using medications that block specific growth signals within cancer cells.

• CAR T-cell Therapy: A cutting-edge treatment where a patient's own T-cells are reprogrammed to kill the lymphoma.

• Stem Cell Transplant: Often utilized if the lymphoma relapses or returns after initial treatment.

Pre-Procedure Preparation

• Performing a physical exam to locate swollen lymph nodes, spleen, or liver.

• Discussing the specific subtype (indolent vs. aggressive) to determine the urgency of treatment.

• Preparing for a biopsy, which is the only definitive way to confirm a lymphoma diagnosis.

• Evaluating heart and lung function if intensive chemotherapy or a stem cell transplant is planned.

Tests Before Lymphoma Treatment

• Lymph Node Biopsy: Surgical removal of a node or tissue sample for laboratory testing.

• PET and CT Scans: Advanced imaging used to determine the location and stage of the cancer.

• Bone Marrow Aspiration: Checking the bone marrow to see if the cancer has spread to the blood-cell "factory."

• Blood Tests: To assess general health and look for markers associated with certain lymphoma types.

Life After Lymphoma Treatment

• For Hodgkin Lymphoma, the 5-year survival rate is now approximately 88%.

• For Non-Hodgkin Lymphoma, the 5-year survival rate is approximately 74%, varying by subtype.

• Regular follow-up scans and blood tests are required to monitor for remission or relapse.

• Many patients with indolent types can live for decades with active surveillance or periodic treatment.

Benefits of Lymphoma Treatment

• High potential for cure, especially in Hodgkin Lymphoma and certain aggressive subtypes.

• Targeted therapies and immunotherapies offer effective options with fewer side effects than traditional chemo.

• CAR T-cell therapy provides a powerful alternative for cases that have not responded to standard care.

• Effectively reduces the size of bulky tumors and alleviates systemic "B symptoms" like fever and weight loss.
