Pathology

Since 1944, several classifications have been proposed for Hodgkin lymphoma (HL). Currently, the World Health Organization (WHO) Classification of Hematologic Malignancies is used:

  1. Lymphocyte predominant, nodular (NLPHL) (5%)

  2. Classic

    1. Lymphocyte-rich (LRCHL) (5%)

    2. Nodular sclerosis (NSHL) (60–80%)

    3. Mixed cellularity (MCHL) (15–30%)

    4. Lymphocyte depleted (LDHL) (1%)

    5. Unclassifiable (<1%)

Work-up

  1. History and physical exam

  2. Laboratory tests: CBC with differential, ESR, electrolytes, albumin, liver function tests, mineral panel, LDH

  3. HIV and hepatitis B and C serologies as clinically indicated

  4. Chest x-ray (PA and lateral)

  5. CT scan of chest, abdomen, and pelvis (and neck in selected cases)

  6. Positron emission tomography (PET) scan if clinically indicated (equivocal CT)

  7. Bone marrow aspirate and biopsy

  8. Pulmonary function tests

  9. Echocardiogram or MUGA scan to determine cardiac ejection fraction

  10. Excisional lymph node biopsy to completely assess lymph node architecture is required at initial diagnosis. Fine-needle aspiration biopsy alone is not desirable for the initial diagnosis of lymphoma

  11. Fertility counseling, if appropriate

Staging

Staging
Ann Arbor Staging Classification for Hodgkin and Non-Hodgkin Lymphomas
Stage Description
I Involvement of a single lymph node region (I) or involvement of a single extralymphatic organ or site (IE)
II Involvement of 2 or more lymph node regions or lymphatic structures on the same side of the diaphragm alone (II) or with involvement of limited, contiguous extralymphatic organ or tissue (IIE)
III Involvement of lymph node regions on both sides of the diaphragm (III), which may include the spleen (IIIS), or limited, contiguous extralymphatic organ or site (IIIE), or both (IIIES)
IV Diffuse or disseminated foci of involvement of one or more extralymphatic organs or tissues with or without associated lymphatic involvement
Abbreviations
A Asymptomatic
B Unexplained persistent or recurrent fever with temperature higher than 38°C (100.4°F) or recurrent drenching night sweats within 1 month or unexplained loss of >10% body weight within 6 months
E Limited direct extension into extralymphatic organ from adjacent lymph node
