• Approach to Heme Malignancies Lymphoma, Multiple Myeloma, Acute Leukemia and Myeloid Disorders Dr. Michelle Geddes University of Calgary and Tom Baker Cancer Centre Nov 26, 2015 Objectives • Organize the approach to working up possible hematologic malignancies • Review presenting symptoms and signs in hematologic malignancies • Outline the approach to therapy in different hematologic malignancies • Review disease and treatment complications Hematopoiesis Lymphoid Malignancies • Lymphoproliferative disorders • B cells 80%, T cells 20% (terrible Ts) • Chronic lymphocytic leukemia/small lymphocytic lymphoma • Acute leukemia (B cell ALL, T cell ALL) Hodgkins Lymphoma – Classical HL – Nodular lymphocyte predominant HL NonHodgkins Lymphomas Indolent Aggressive Diffuse large B Follicular cell lymphoma Gastric MALT Small lymphocytic Peripheral T Cell lymphoma lymphoma Double hit Waldenstroms lymphoma Mantle cell lymphoma Very Aggressive Burkitt Lymphoblastic lymphoma Case 1 – possible lymphoma • 23 year old woman with cervical lymph node present for one month • No infectious or B symptoms • Pruritis On exam – Temp 38 C • 3 cm left anterior cervical LN, 4 cm left supraclavicular lymph node Labs - CBC – normal except WBC 15, neutrophils 13.2, eosinophils 1 • LDH elevated at 420 WHAT TESTS WOULD BE HELPFUL TO DETERMINE IF LYMPHOMA? Making a Diagnosis… • BIOPSY the Node! – Excisional biopsy>needle core>FNA • Other bloodwork can be helpful: – CBC – LDH – ESR – B2 microglobulin – SPEP, quant immunoglobulins • Bone marrow biopsy usually a staging procedure, not preferred as diagnostic test A BIOPSY IS DONE… Hodgkins lymphoma – Reed Sternberg cell Hodgkins Lymphoma B cell lymphoma with surrounding reactive T cells NOW WHAT? STAGING LYMPHOMA Lymph Node Regions Staging (Ann Arbour System) A – no B Symptoms B – presence of B Symptoms Staging Hodgkins Lymphoma • • • • Physical Exam History of B symptoms CT neck, chest, abdomen and pelvis ? Bone marrow biopsy – Not necessary if less than stage IIB HYL as unlikely to be involved (unlike NHL) • Hodgkins tends to have orderly spread • PET scan – If limited stage disease, confirm with PET scan PET scan Treatment and Prognosis in Hodgkins Lymphoma Hodgkins Lymphoma Limited Stage (I-II) Favourable risk Advanced Stage (III-IV) Unfavourable risk -large mediastinal adenopathy -age >50 ESR >50 or >30 w/ B Sx ≥4 lymph node areas Treatment and prognosis of Limited Stage HL • Favourable risk: – ABVD (adriamycin, bleomycin, vinblastine and dacarbazine) x2 and 30 Gy involved field RT • Unfavourable risk: – 4 cycles ABVD and 30 Gy IFRT – If B symptoms or bulky 6 cycles ABVD and IFRT Treatment and prognosis of advanced stage HL • Good risk: ABVD x 6 +/- RT • If adverse risk factors: – Escalated dose BEACOPP • Bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, prednisone • More toxicities and infertility, MDS than ABVD; ABVD used in those with few risk factors and elderly – PET CT scan after therapy for residual disease LOW GRADE NON-HODGKINS LYMPHOMAS Case 2 • 64 year old man comes to see his GP with an enlarged lymph node in his groin • Feels otherwise well, no B symptoms, no symptoms related to enlarged node • Physical exam shows 2 cm LN in both axillae • CBC, LDH, SPEP normal • A diagnostic procedure is performed… Follicular Lymphoma Follicular lymphoma • 70% of all low grade lymphomas • Older population, usually relatively asymptomatic at diagnosis with long history of waxing and waning lymph nodes – 75% with advanced stage • Approximately 25% will transform at some time to an aggressive DLCL Treatment of Follicular Lymphomas • Generally watch and wait until symptomatic – Most treatment not curative – Exception – stage 1a or IIa nonbulky contiguous disease given RT for cure • Rituximab-Bendamustine is mainstay of first line therapy treatment indicated – fever, night sweats, weight loss, malaise, pain – Bulky or symptomatic lymphadenopathy – Impending organ compromise (compression, pleural/pericardial effusions, ascites) – Cytopenias secondary to bone marrow infiltration Treatment of Follicular Lymphomas • Maintenance rituximab given q3 months for two years to prevent relapse and improve survival Indolent Lymphomas Follicular Lymphoma JCO 2009: 10;1607-14 Prognosis in Follicular Lymphoma Specific indolent lymphomas have different treatment approach • Mantle cell lymphoma – “indolent” lymphoma but relatively aggressive course with med survival 3-5y – R-CHOP then DHAP and autologous stem cell transplant up front, maintenance Rituximab • Gastric MALT, cutaneous indolent lymphomas • Splenic marginal zone lymphoma ‘ – Splenectomy • Hairy cell leukemia – Splenomegaly and cytopenias – Cladrabine single 5-7 day course: 91% CR, OS at 4y 96% AGGRESSIVE LYMPHOMAS Case 3 • 54 year old patient presents with rapid development over 2-3 weeks of large left supraclavicular lymph node – Fevers, drenching sweats – Appetite poor, weight loss10 lbs • On exam: 5 cm left supraclavicular node – Cachexia • A diagnostic procedure is performed… Diffuse large B cell lymphoma Diffuse large B cell lymphoma • Most common type of lymphoma, incidence increases with age – 25% of all NHL • • • • Rapidly growing LNs, 30% have B symptoms Advanced disease>localized disease 30% bone marrow involvement, most high LDH Can be extranodal disease – 5-10% risk of CNS relapse Treatment of DLCL • Limited stage (I-IIa non-bulky) – If 0-1 IPI risk factors: R-CHOPx3 + IFRT – If 3 risk factors: R-CHOP x 6 • Advanced stage (stage III-IV, bulky, B symptoms) – R-CHOP x6 – Add IFRT to sites of prior bulk – PET scan after completion of therapy Prognosis - International Prognotistic Index T cell aggressive lymphomas • Overall, prognosis is worse than B cell aggressive lymphomas • Can present with T symptoms – terrible B symptoms, systemic symptoms T cell lymphoma outcomes Foss F M et al.

Myeloid disorders • Myelodysplastic syndromes • Myeloproliferative disorders – Essential thrombocytosis, polycythemia vera, myelofibrosis – CML – tyrosine kinase inhibitors • Acute myeloid leukemia – Intensive inpatient protocols with allogeneic transplantation in high risk patients – Hypomethylating agents or low dose cytarabine in the elderly What raises a red flag that there is a myeloid disorder? • Reasons to refer urgently: – Blasts – always! – Nucleated red blood cells – >1 unexplained cytopenia or a severe cytopenia – Unexplained elevated blood counts: • Hb >185 in men or Hb>165 in women – check epo levels, jak2V617F mutation if no obvious explanation for high Hb • Thrombocytosis >450 persistent – look for reactive causes, iron deficiency • Elevated white blood cells with left shift Myelodysplastic Syndromes • Clonal disorders of the bone marrow characterized by: – Low blood counts – Ineffective production of blood cells – Abnormal red cells, neutrophils and platelets – Increased risk of developing AML Mr. G. Olfer • • • • 72 yo man with anemia for 4 years Mildly low neutrophil count, no infections Platelets normal, no bleeding Now hemoglobin down to 60s, transfusion dependent with 4u red cells transfused • Bone marrow biopsy shows MDS • Refractory anemia with ringed sideroblasts • What does this mean for him?

Blood. 2012;120(12):2454 Lower risk MDS • Growth factors i.e. erythropoietin – increase red cells and reduce transfusions • Transfusions, antibiotics, supportive care • Iron chelation for iron overload from transfusions – Usually if ferritin>1000 and/or 20 transfusions red cells Del 5q syndrome • 10-15% of MDS – Anemia – Mild low white blood cells – Atypical megakaryocytes, normal to elevated platelets – Transfusion dependence – Normal blast count Extended survival with low frequency of AML transformation (10%) Lenalidomide: RBC Transfusion Independence in Del(5q) MDS Erythroid Response Rate (N=148) n (%) 95% CI Transfusion independence* 99 (67) 59–74 ≥50% decrease in no. transfusions 13 (9) 5–15 Total transfusion response 112 (76) 68–82 Transfusion Independence Response Characteristics Median Range Time to response (wk) 46 1–49 Hgb increase† (g/dL) 54 11–114 N Eng J Med, 2006; 355: 1456 Mr. G.
