Hematologic Malignancies Leukemia • Malignancy of hematopoietic cells • Starts in bone marrow, can spread to blood, nodes • Myeloid or lymphoid • Acute or chronic Lymphoma • Malignancy of hematopoietic cells • Starts in lymph nodes, can spread to blood, marrow • Lymphoid only • Hodgkin or non-Hodgkin
Leukemias Hematologic Malignancies • Acute leukemias • Chronic leukemias Lymphomas • Hodgkin lymphoma • Non-Hodgkin lymphoma Plasma cell disorders • Multiple myeloma
Leukemias Hematologic Malignancies • Acute leukemias • Chronic leukemias Lymphomas • Hodgkin lymphoma • Non-Hodgkin lymphoma
Causes of lymphadenopathy • Most common cause overall: benign reaction to infection • Most common malignant cause: metastatic carcinoma
Non-Hodgkin Lymphoma • Malignant proliferation of lymphoid cells (blasts or mature cells) in lymph nodes • Skips around • Many subtypes • Most are B cell Things you must know
Symptoms of NHL • Painless, firm lymphadenopathy • Extranodal manifestations • “B” symptoms: weight loss, night sweats, fever
Older patients Indolent (incurable!) Small, mature cells Non-destructive Children, sometimes Aggressive (curable?) Big, ugly cells Destructive Features of Low-Grade vs. High-Grade NHL Low-grade High-grade
Small lymphocytic lymphoma Malt lymphoma Follicular lymphoma Mycosis fungoides Low-grade Types of NHL High-grade • Large cell lymphoma • Lymphoblastic lymphoma • Burkitt lymphoma
Small Lymphocytic Lymphoma • Small mature lymphocytes • Same thing as CLL • CD5+ • Long course; death from infection Things you must know
MALT Lymphoma • Occurs in mucosa-associated lymphoid tissue • Associated with Helicobacter pylori • Early on, can be cured with antibiotics Things you must know
Follicular Lymphoma • Follicular pattern (later diffuse) • Small cleaved cell, mixed or large cell • Grade 1, 2, or3 • t(14;18) - IgH and bcl-2 Things you must know
I II III Follicular lymphoma
Staging and Prognosis of Follicular Lymphoma Stage I Stage II Stage III Stage IV Single node Two or more nodes on same side of diaphragm Lymph nodes on both sides of the diaphragm Diffuse extranodal involvement 90% 5ys 40% 5ys A = no additional symptoms B = weight loss, night sweats, fever
Mycosis Fungoides/Sézary Syndrome • Skin lesions • Blood involvement • Cerebriform lymphocytes • T-cell immunophenotype Things you must know
Diffuse Large-Cell Lymphoma • Large B cells • Extranodal involvement • Grows rapidly • Bad prognosis Things you must know
Lymphoblastic Lymphoma • Typical patient: teenage male with mediastinal mass • Lymphoblasts in diffuse pattern • Same as ALL* * Which kinds of ALL? Things you must know
Burkitt Lymphoma • Children, young adults • Fast-growing • Extranodal mass • Starry-sky pattern Things you must know
Hodgkin Lymphoma • Younger patients, good prognosis • Contiguous spread • Five subtypes • Reed-Sternberg cell Things you must know
