Non-Hodgkin’s Lymphoma • 6 th most common cause of cancer death in United States. • Increasing in incidence and mortality. • Since 1970, the incidence of lymphoma has almost doubled.
Overview • The types of non- Hodgkin’s lymphoma reflect the developmental stages of lymphocytes. • Each type of lymphoma can be viewed as a lymphocyte arrested at a certain stage of development and transformed into a malignant cell. • 85% B cell origin, the rest T or null cell.

WHO Classification
Types of Non-Hodgkin’s Lymphoma Small lymphocytic Immunoblastic Mantle cell Large Cell
Etiology of NHL • Immune suppression – congenital (Wiskott-Aldrich) – organ transplant (cyclosporine) – AIDS – increasing age • DNA repair defects – ataxia telangiectasia – xeroderma pigmentosum
Etiology of NHL • Chronic inflammation and antigenic stimulation – Helicobacter pylori inflammation, stomach – Chlamydia psittaci inflammation, ocular adnexal tissues – Sjögren’s syndrome • Viral causes – EBV and Burkitt’s lymphoma – HTLV-I and T cell leukemia-lymphoma – HTLV-V and cutaneous T cell lymphoma – Hepatitis C
Epidemiology • Can occur at any age • Overall incidence, and incidence of subtypes, varies with location: – Burkitt’s in tropical Africa – IPSID in Middle East – Adult T cell leukemia-lymphoma in Japan and Caribbean
Epidemiology • Indolent lymphomas are rare in young people and increase in incidence with age. • Large cell lymphoma (DHL) is less age related, and is among most common cancers affecting the young. • Burkitt’s and lymphoblastic lymphoma are common in adolescents. • AIDS patients develop aggressive, high grade lymphomas.
Clinical Features • • • Lymphadenopathy Cytopenias Systemic symptoms Hepatosplenomegaly Fever Night sweats
Clinical Features • Lymphadenopathy may fluctuate or spontaneously remit, especially in low-grade lymphomas. • B symptoms more common in high-grade lymphomas. • Hematogenous spread of disease, with no predictable pattern.
Clinical Features • Classic lymphoma: arises in lymph node or bone marrow. • Extranodal primary more common in high -grade lymphoma. • Waldeyer’s ring involvement frequent in GI lymphomas.
Diagnosis of NHL • Excisional biopsy is preferred to show nodal architecture (follicular vs diffuse). • Immunohistochemistry to confirm cells are lymphoid – LCA (leukocyte common antigen) – Monoclonal staining with Igk or Igl • Flow cytometry: – CD 19, CD 20 for B cell lymphomas – CD 3, CD 4, CD 8 for T cell lymphomas
Diagnosis of NHL • Chromosome changes – 14; 18 translocation in follicular lymphoma • bcl-2 oncogene – t(8; 14), t(2; 8), t(8; 22) in Burkitt’s lymphoma • c-myc oncogene – t(11; 14) in mantle cell lymphoma • cyclin D 1 gene
Staging Workup • • CBC, chemistries, urinalysis CT scans of chest, abdomen and pelvis Bone marrow biopsy and aspirate (Lumbar puncture) – AIDS lymphoma – T cell lymphoblastic lymphoma – High grade lymphoma with positive marrow
Staging laparotomy and lymphangiogram are not indicated in non-Hodgkin’s lymphoma.
Staging: Ann Arbor I. 1 lymph node region or structure II. >1 lymph node region or structure, same side of diaphragm III. Both sides of diaphragm IV. Extranodal sites beyond “E” designation subscripts: A, B, E, S
Treatment Options: Indolent lymphomas WDLL, NPDL • 10 -15% in Stage I or II – potentially curable – local radiotherapy • 85 -90% Stage III or IV – incurable – treatment does not prolong survival
Reasons to Treat in Advanced Indolent Lymphomas • • • Constitutional symptoms Anatomic obstruction Organ dysfunction Cosmetic considerations Painful lymph nodes Cytopenias
Treatment Options in Advanced Indolent Lymphomas • Observation only. • Radiotherapy to site of problem. • Systemic chemotherapy – oral agents: chlorambucil and prednisone – IV agents: CHOP, COP, fludarabine, 2 -CDA. • Antibody against CD 20: Rituxan, Bexxar, Zevalin. • Stem cell or bone marrow transplant.
CHOP Chemotherapy • • Cyclophosphamide (Cytoxan) Hydroxydaunorubicin (Adriamycin) Oncovin (vincristine) Prednisone
Treatment Options: Aggressive Lymphomas Aggressive • Diffuse large cell lymphoma, large cell anaplastic lymphoma, peripheral T cell lymphoma. Very Aggressive • Burkitt’s lymphoma and lymphoblastic lymphoma.
Treatment Options for Early Stage Aggressive Lymphomas • Often in Stage I or II – potentially curable – disseminates through bloodstream early – must use systemic chemotherapy • CHOP x 6 cycles • CHOP x 3 cycles followed by radiotherapy
Treatment Options for Advanced Stage Aggressive Lymphomas • Systemic chemotherapy – CHOP (± Rituxan for over 70 age group) • ± Intrathecal chemotherapy – AIDS patients and CNS involvement • ± Radiotherapy – Spinal cord compression, bulky disease
Lymphoblastic Lymphoma • • T cell malignancy. Male adolescents. Mediastinal mass. T cell variant of T cell acute lymphoblastic leukemia. • Prognosis improving with intensive ALL regimens.
Burkitt’s Lymphoma • African variety: jaw tumor, strongly linked to Epstein-Barr Virus infection. • In U. S. , about 50% EBV infection. • May present as abdominal mass. • Most rapidly growing human tumor. • Typical chromosome abnormality: c-myc oncogene linked to one of the immunoglobulin genes.
Burkitt’s Lymphoma • Treated with multidrug regimen similar to pediatric leukemia/lymphoma regimens.
Notable Subtypes of Lymphoma
Mycosis Fungoides • Malignancy of helper T cells. • Affinity for skin. • Can be treated with electron beam radiation, ultraviolet light, or topical alkylating agents.
AIDS Lymphoma • Aggressive lymphomas of B cell origin. • Burkitt’s, Burkitt’s-like, and large cell immunoblastic. • Treatment often limited by immune compromise of the patient. • Prognosis improved with HAART therapy.
MALT Lymphoma • Mucosa-Associated Lymphoid Tissue • Chronic infection of the stomach by Helicobacter pylori. • Localized to the stomach, indolent course. • Can be cured in many cases by antibiotics against H. pylori.
Ocular Adnexal Lymphoma (OAL) A lymphoma affecting the tissues surrounding the eye that may arise after chronic inflammation.
Treatment • May respond to antibiotic therapy against Chlamydia. • One patient treated with doxycycline (100 mg bid for 3 weeks) had complete remission for more than 12 months, and another patient had minimal remission for more than 18 months. ASCO 2003, Abstract 2273
Hodgkin’s Disease
Thomas Hodgkin English pathologist, described the disease that bears his name in 1832.
Paul Allen Cofounded Microsoft with Bill Gates
Mario Lemieux Top player in the US National Hockey League
Brandon Tartikoff Youngest US television network president (Cosby, Seinfeld)
Hodgkin’s Disease • One-seventh as common a snon-Hodgkin’s lymphoma. • Highly treatable and curable, even when disseminated. • Presence of Reed-Sternberg cell is necessary to make diagnosis.
Reed-Sternberg Cell
Subtypes of Hodgkin’s Disease • • Lymphocyte predominant Nodular sclerosis Mixed cellularity Lymphocyte depleted Unlike non-Hodgkin’s lymphoma, in Hodgkin’s Disease the histologic subtype does not determine how the disease is treated.
Etiology of Hodgkin’s Disease • Reed-Sternberg cells are the malignant cells. • Minor population in the malignant tissues – many normal lymphocytes, eosinophils, other cells • Cell of origin is unknown: T, B, both, neither. • Some R-S cells contain EBV genomes.
Epidemiology • In developed countries, bimodal distribution of patients. – young adulthood – after age 50 • More common in affluent families with few siblings. • In developing countries, more common in young children.
Signs and Symptoms • Lymph node enlargement, usually cervical or mediastinal. • Systemic “B” symptoms common. • Pel-Ebstein fever. – relapsing, high-grade fever that can reach 105106°F, periodicity of 7 -10 days. Fever spikes abrupt in onset and resolution • Pain on drinking alcohol.
Pel-Ebstein Fever
Clinical Features • T cell mediated immune deficiency, even in early stage disease. Prone to infections: – Herpes zoster (“shingles”) in one fourth of patients – Fungal or mycobacterial infections • Immune defect may persist even after lymphoma is cured.
Clinical Features • Predictable contiguous spread of disease: – cervical nodes to mediastinum or axilla – mediastinum to periaortic nodes or spleen, etc. • Basis for staging and treatment decisions.
Diagnosis • Excisional biopsy of a lymph node. Fine needle aspirate is not sufficient to make the diagnosis of Hodgkin’s disease.
Staging of Hodgkin’s Disease Same as for non-Hodgkin’s: • H + P, labs, CT scans, bone marrow biopsy PLUS: • Gallium scan • Lymphangiogram or staging laparotomy ONLY if results would affect treatment decisions
Treatment by Stage
Chemotherapy Regimens • MOPP – Mechlorethamine, Oncovin, Procarbazine, Prednisone • ABVD – Adriamycin, Bleomycin, Vinblastine, Dacarbazine • BEACOPP
Treatment Options • Often, patients who relapse after radiotherapy can be cured by salvage chemotherapy. • Combined chemotherapy and radiotherapy is given for bulky mediastinal masses. • Chemotherapy now being tested for earlier stages of the disease.
Late Complications of Hodgkin’s Disease • High incidence of second malignancies – leukemia first 10 years, solid tumors over time. • Leukemia in patients receiving alkylating agents or combined chemo/XRT. • Lung cancer and breast cancer in patients receiving XRT to chest. Lung cancer especially high in smokers.
Late Complications of Hodgkin’s Disease • Hypothyroidism after irradiation of the neck. • Constrictive pericarditis after radiotherapy to the mediastinum. • Infertility after use of alkylating agents. • Heart failure after Adriamycin treatment.
Multiple Myeloma
Ann Landers Advice Columnist
Mark Lenard Sarek (Spock’s father) on Star Trek
Overview of Multiple Myeloma • Less common than non-Hodgkin’s lymphoma, more deadly. • Average life expectancy 30 -36 months. • Some patients develop a very indolent form and live for 10 years or more. • Potentially curable with high dose chemotherapy (bone marrow or stem cell transplantation).
Overview of Multiple Myeloma • Disease of malignant B-lymphocytes. • Little similarity to lymphoma in presentation, age at diagnosis, treatment, or prognosis. • Signs and symptoms of multiple myeloma are quite variable. • Approximately 20% of patients have no symptoms.
Etiology of Multiple Myeloma • Unknown. Suggested predisposing factors include: – Viral infection with Human Herpesvirus 8 (HHV-8). – MGUS (monoclonal gammopathy of undetermined significance).
Epidemiology • • • Average at presentation is about 65. Males are affected more often than females. Incidence in blacks is twice that of whites. Five-year survival is approximately 25 -30%. Median survival 30 -36 months.
Multiple Myeloma • More than 15% plasma cells in the bone marrow. • Monoclonal immunoglobulin peak on SPEP – more than 3 gm/d. L. • Presence of Bence Jones protein in urine. • Decreased levels of normal immunoglobulins.
Clinical Features • Bone marrow failure - Anemia, thrombocytopenia, neutropenia • Renal failure • Bone disease with skeletal destruction – lytic lesions – generalized decrease in bone density • Hypercalcemia
Clinical Features • Hyperviscosity syndrome • Recurrent infections • Amyloidosis
Diagnosis and Staging Workup • Bone marrow biopsy and aspirate • Serum protein electrophoresis and immunofixation • Skeletal survey – Plain x-rays are better than bone scan. – Lytic lesions do not show up well on bone scan. • Quantitative immunoglobulins

Durie-Salmon Staging System for Multiple Myeloma Stage I Low myeloma cell mass • Hemoglobin > 10 g/d. L • Normal bone, or solitary plasmacytoma • Low immunoglobulin spike (M-component) – Ig. G < 5 g/d. L, Ig. A < 3 g/d. L – Bence-Jones protein < 4 g/24 h
Durie-Salmon Staging System for Multiple Myeloma Stage III High myeloma cell mass • Hemoglobin < 8. 5 g/d. L • Serum calcium > 12 mg/d. L • Multiple lytic bone lesions on x-ray • High M-component – Ig. G > 7 g/d. L, Ig. A > 5 g/d. L – Bence-Jones protein > 12 g/24 h
Durie-Salmon Staging System for Multiple Myeloma Stage II Intermediate myeloma cell mass • In between Stages I and III Subclassification A: Normal renal function - serum creatinine level < 2. 0 mg/d. L B: Abnormal renal function - serum creatinine level ³ 2. 0 mg/d. L
Treatment of Multiple Myeloma Standard Chemotherapy • Melphalan and prednisone • VAD (vincristine, adriamycin, dexamethasone) High Dose Chemotherapy • Bone marrow transplant • Peripheral stem cell transplant
Treatment of Multiple Myeloma Other Modalities • Pulse dexamethasone • Interferon • Local radiotherapy to bony lesions • Pamidronate and other bisphonates • Thalidomide • Velcade (Bortezomib, PS-341) • Bendamustine
Prognostic Factors Poor prognosis: • • Age > 65 High tumor mass High b 2 microglobulin Renal failure, hypercalcemia
Conclusions: Lymphoma and Multiple Myeloma • • Malignancies of B cells. Sometimes preventable. Highly treatable and often curable. Study of these diseases have led to important advances in the understanding of the biology of lymphoid cells.
