How is Classic Hodgkin Lymphoma Diagnosed?
Published: Apr 04, 2024
Diagnosing Classic Hodgkin Lymphoma (cHL) involves a series of tests and evaluations. Learn about the crucial steps involved in pinpointing this condition.
Initial Evaluation and Symptoms
The first step in diagnosing cHL is a thorough medical history and physical examination. Doctors look for signs of swollen lymph nodes, fever, night sweats, and weight loss. They also inquire about any history of previous cancers or family history of similar conditions. These initial observations guide the subsequent tests needed for a definitive diagnosis.
Laboratory Tests and Imaging
Blood tests, including a complete blood count (CBC), help detect abnormalities like anemia or elevated white blood cell counts. Imaging tests, such as PET/CT scans, are used to visualize the extent of the disease and identify the best areas for biopsy. These tests are crucial in determining the stage of the disease and guiding treatment plans.
The Importance of Biopsy
A biopsy is essential for confirming a cHL diagnosis. An excisional biopsy, where an entire lymph node is removed, provides the most accurate results. This procedure allows pathologists to examine the tissue under a microscope, looking for the characteristic Hodgkin/Reed-Sternberg cells that define cHL. This step is critical for differentiating cHL from other types of lymphomas.
Evaluating Extranodal Involvement
In some cases, cHL may spread to organs outside the lymphatic system, like the liver or bone marrow. Specialized imaging and tests, such as liver function tests or bone marrow biopsy, help evaluate this spread. Detecting extranodal involvement is vital for staging the disease and planning appropriate treatments.
