Hematology Review in Myeloid and Lymphoid Disease

Veteran General Hospital


Indication of allo hsct in aml in 1st cr
Indication of Allo-HSCT in AML in 1st CR

  • Intermediate risk: If matching sibling donor available( normal karyotype with NPM1- or FLT3+, +8, +6, -Y )

  • High risk( chromosome 5, 7or complex )

Appelbaum, ASCO 2008

Indication of allohsct in all
Indication of AlloHSCT in ALL

  • Matching sibling donor: all risk group adult ALL in 1st CR

  • Matching unrelated donor: high risk group t( 4,11 ), complex. Ph+ in 1st CR and all disease beyond 1st CR

Appelbaum, ASCO 2008

Donor lymphocyte infusion
Donor Lymphocyte Infusion

  • Most promising in CML CP

  • Myeloma, Low grade NHL and Hodgkin’s lymphoma: modest effect

  • AML and high grade NHL: not satisfied

  • ALL: disappointing

Mackinnon, ASCO 2008

Reduced intensity hsct
Reduced Intensity HSCT

  • Graft-versus leukemia/lymphoma

  • Lower toxicity of conditioning regimen but higher relapse rate

  • Extend to older age people

  • Risk of GVHD: similar to conventional dose HSCT but pattern of onset is different

  • Onset of aGVHD may be delayed by weeks to months

Antin 2007 Hematology

Reduced intensity hsct1
Reduced Intensity HSCT

  • Not a very effective cytoreductive therapy

  • Performed in reasonable control of the disease

  • Immune mechanism “GVL”

  • Tumors could not provide co-stimulatory signals may be poor targets

  • Proliferative rapidly may be difficult for the immune system to control

  • Extensive disease more resistant than minimal disease

Antin 2007 Hematology

Reduced intensity hsct2
Reduced-Intensity HSCT

  • Less aggressive course and lower proliferative rates

  • CML, CLL, low grade NHL: excellent rates of disease control

  • High grade NHL and Hodgkin lymphoma: wait for further study

  • AML/MDS: successful especially in CR status

  • ALL: much less amenable to GVL and best in CR status

  • MM: Good candidate for immunologic control

Antin 2007 Hematology

Graft versus host disease
Graft versus Host Disease

  • Multifactorial pathogenesis

  • Conditioning regimen toxicity that exposes neoantigens

  • Enhances cytokines release

  • Augments APC presentation of alloantigen to incoming donor T cells

  • Initiates immunologic storm

  • Donor T cells activated by alloantigen expand and migrate to lymphoid organs and expansion

  • Cytokine and cytolytic apoptotic injury

Weisdorf, Hematology 2007

Graft versus host disease1
Graft versus Host Disease

  • Skin, liver, and gut, probably lung

  • aGVHD 30-50% in sibling donor

  • Higher incidence in MUD

  • Dierct organ injury requiring immunosupressive therapy

  • Secondary risks of infection

  • Hightened risks of cGVHD

  • Enhanced antitumor effect

Weisdorf, Hematology 2007

Graft versus host disease2
Graft versus Host Disease

  • Cytotoxic T cells and inflammatory cytokines produce injury to GVHD target organs through direct cytolytic effect and induction of apoptosis

  • Antibody-mediated B-cell responses may be involved in GVHD as well

Weisdorf, Hematology 2007

Presentation of acute gvhd
Presentation of Acute GVHD

  • Erythematous skin rash progressing to bullae in most severe form

  • Predilection for dorsal surfaces of extremities, malar regions, tops of the ear, back of neck and involvement of palms and soles

  • GI tract involvement: nausea, anorexia, vomiting( UGI ); watery, protein-rich, secretory diarrhea that can progress to bloody diarrhea or ileus

  • Hepatic involvement: targets the biliary epithelium with cholestasis and Alk-P elevation

  • Few case with GI tract or liver involvement only without skin rashes

Weisdorf, Hematology 2007

Variant presentation of gvhd
Variant Presentation of GVHD

  • Umbilical cord: less frequent or less severe

  • RIC or nomyeloablative: later and slower in evolution of aGVHD but similar in cGVHD

Weisdorf, Hematology 2007

Infection complication of gvhd
Infection Complication of GVHD

  • Immunosuppressive and further immunosuppressive therapy produced lymphopenia

  • Disrupted cutaneous and epithelium

  • CMV reactivation, invasive fungal infection, PCP, VZV, bacterial infection ( pneumococcal and H. influenzae)

Weisdorf, Hematology 2007

Treatment of agvhd
Treatment of aGVHD

  • Suppression of T-cell activation, cytokine release and re-establishment of donor-host immunotolerance

  • Blunt T-cell activation and facilitate Treg cell expansion

  • Initial therapy: 1-2 mg/kg/day prednisone, 30-50% response

  • Limited-severity, upper-GI-only GVHD: oral budesonide or beclomethasone with hlow dose prednisone

Weisdorf, Hematology 2007

Treatment of agvhd1
Treatment of aGVHD

  • MMF

  • Etanercept( TNF-alpha receptor fusion protein )

  • Denileukin diftitox( Ontak, IL-2 diphtheria toxin )

  • Pentostatin

  • Daclizumab( IL-2R alpah receptor Ab )

  • Infliximab( anti-TNF alpha Ab )

  • ATG

  • Sirolimus, alemtzumab, mesenchymal stem cells

Weisdorf, Hematology 2007

Presentation of chronic gvhd
Presentation of Chronic GVHD

  • Similar with aGVHD: skin, GI and Liver

  • Sicca syndrome

  • Obstructive broncholitis

  • Lichenoid or sclerotic skin change

  • Esophageal dysmotility, fasciitis, arthropathy and autoimmune manifestation

Weisdorf, Hematology 2007

Treatment of cgvhd
Treatment of cGVHD

  • Extended duration of immunosuppressive therapy

  • Corticosteroid and calcineurin inhibitors

  • Newer agent: MMF, sirolimus, pentostatin, extracoporeal photophresis

  • Rituximab and thalidomide ?

Weisdorf, Hematology 2007


  • Major risk factor for cGVHD: preceding aGVHD

  • Most important cause of nonrelapse mortality and limiting quality of life

  • Associated with protection against malignancy

  • The extent and severity do not directly correlate with protection against relapse

Weisdorf, Hematology 2007

Chronic lymphocytic leukemia
Chronic Lymphocytic Leukemia

  • 80% CLL with cytogenetic lesions with FISH

  • Del 13q: most common

  • Trisomy 12

  • Del 11q

Kipps, ASCO 2008

Chronic lymphocytic leukemia1
Chronic Lymphocytic Leukemia

  • Soluble CD23, thymidine kinase, beta2M, MMP9, IL-8, IL6, CD44: poorer survival or shorter PFS

  • Not capable of identifying patients at diagnosis who are at increased risk for PD

Kipps, ASCO 2008

Ighv somatic hypermutation and zap 70 in cll
IgHV somatic hypermutation and ZAP-70 in CLL

  • Aggressive clinical course in unmutated

  • Indolent course in somatic hypermutated

  • ZAP-70 express in unmutated

  • ZAP-70 enhance the signaling capacity of the surface Ig expressed in CLL derive more stimulation from self and environmental antigens increased proliferation and/or resistance to apoptosis

Kipps, ASCO 2008

Micrornas in cll
MicroRNAs in CLL

  • Inhibit gene expression by causing either degradation or blocking the translation of target mRNA

  • Regulate gene expression in development and disease

  • miRNA gene in del 13q: miR15a and miR16-1

  • Abnormal, low-level expression of miR15a and miR16-1 can lead to a disease of CD5-positive B cells in both mice and human

Kipps, ASCO 2008

Time to treatment of cll
Time to Treatment of CLL

  • NCI-working group criteria( revised 2008 )

  • Should not be treated solely on the basis of prognostic markers except in clinic trial

  • Monitor without therapy in asymptomatic early stage disease( Rai 0 to 1, Binet A ) unless PD

  • PD: progressive BM failure worsening anemia and/or thrombocytopenia, progressive lymphocytosis with an increase > 50% over 2 months, lymphocyte doubling time< 6 months, massive or progressive LAP, massive or progressive splenomegaly

  • Intractable autoimmune anemia or thrombocytopenia

Kipps, ASCO 2008

Time to treatment of cll1
Time to Treatment of CLL

Kipps, ASCO 2008

Hsct in cll

  • Incurable with standard treatment

  • Autologous HSCT: low treatment-related mortality but high relapse

  • Reducing short-term morbidity and mortality of alloHSCT

  • Allow transplantation in older patient

  • Alemtuzumab decreased GVHD but delayed post-HSCT immune reconstitution, increased infection risk and impaired GVL

Gribben, ASCO 2008

Treatment of cll
Treatment of CLL

  • Prognostic factors for time to treatment and survival : mutation status of IgHV, ZAP-70, CD38 expression, B2M, soluble CD23, del 17p, 11q by FISH

  • Early treatment with chemotherapy for patients without indications or based solely on prognostic factor status should be administered only in the context of a clinical trial

  • NCI-WG guideline revised 2008 ( Blood 2008 111: 5446-5456 )

Wierda, ASCO 2008

Treatment of cll1
Treatment of CLL

  • Alkylating agent based: chlorambucil, palliative, CR< 10%

  • Purine analog based: higher CR and longer remission duration, No different OS

  • Purine analog with alkylating agents: higher CR, OR, PFS with FC vs F; more myelosuppression in FC without increase of infection

  • No trial confirmed survival advantage

  • IVIG for recurrent infection with hypogammablobulinemia

Wierda, ASCO 2008, Kay, Hematology 2007

Treatment of cll2
Treatment of CLL

  • Alemtuzumab: single agent activity in Flu refractory disease, sc better tolerated than iv, better response but no survival difference with chlorambucil, only drug with response to p53 abnormality( del17p )

Hodgkin lymphoma
Hodgkin Lymphoma

  • High cure rate

  • From extended field irridation and alkylating-based agents to anthracycline-based with involved filed irridation

  • ABVD preserved most fertility of men and women but should care pulmonary toxicity

  • PET a powerful functional imaging tool for restaging and response assessment

  • Highly predictive at the conclusion of chemotherapy

Horning Hematology 2007

Hodgkin lymphoma3
Hodgkin Lymphoma

Initial Therapy of Multiple Myeloma

  • Eligible to transplantation

  • All with phase III data

  • Thalidomide + Dexamethasone

  • Lenalidomide + Dexamethasone

  • Bortezomib + Dexamethasone

  • Bortezomib + Thalidomide + Dexamethasone

Rajkumar ASCO 2008

Initial therapy of multiple myeloma1
Initial Therapy of Multiple Myeloma

  • Thalidomide + Dexamethasone

  • Most used induction regimen in U.S.

  • More DVT than dexamethasone alone

  • Lenalidomide + Dexamethasone

  • Lower stem cell yield with small proportion of patient not collecting adequate amount

  • Bortezomib + Dexamethasone

  • Higher CR and VGPR than VAD

  • Bortezomib + Thalidomide + Dexamethasone

  • CR + VGPR > TD

Rajkumar ASCO 2008

Initial therapy of multiple myeloma2
Initial Therapy of Multiple Myeloma

  • Thalidomide and lenalidomide: higher incidence of DVT

  • Lenalidomide not suitable for renal failure

  • VTD most active regimen for renal failure who need a rapid response

  • In newly diagnosed MM, dexamethasone in combination should be low( < 40 mg/week )

  • High dose dexamethasone is asociated with unfavorable survival

Rajkumar ASCO 2008

Initial therapy of multiple myeloma3
Initial Therapy of Multiple Myeloma

  • Not eligible for transplantation

  • Melphalan/prednosone/thalidomide (MPT)

  • Bortezomib/melphalan/prednisolone (VMP)

  • MPT and VMP demonstrate superior response rate and progression free even overall survival to MP

  • VMP overcome adverse cytogenetics but more neurotoxicity

Rajkumar ASCO 2008

Dose of concomitant corticosteroid
Dose of Concomitant Corticosteroid

  • ECOG compared dexamethasone in low dose and high dose combined lenalidomide

  • Low dose is better than high dose in DVT and infection rate; higher overall survival, lower toxic and disease related death

  • Low dose steroid is safer and more effective in newly diagnosed MM

Rajkumar ASCO 2008

Goal of therapy
Goal of Therapy

  • Not response rate or CR rate

  • Failed to show a consistent association with overall survival in numerous trials

  • Most CR is temporary and inevitable relapse

  • IFM 99-06, Bologna 96, MAG trial, TT II all failed to showed correlation of CR with overall survival in MM

  • For non-transplant candidate, improve overall survival is the goal

  • For transplant candidate, safest, least-toxic regimen for pretransplant induction therapy

Rajkumar ASCO 2008

Duration of therapy
Duration of Therapy

  • Fixed duration as tolerated

  • MPT < 18 months

  • VMP < 12 months

  • LD indefinite but stop steroid after 1 year

  • VD, VTD, TD restrict to neurotoxicity

Rajkumar ASCO 2008

Role of sct in mm
Role of SCT in MM

  • Prolong survival in IFM, English and Italian study

  • Large U.S., MAG and Spanish study, no survival benefit

  • Different design and duration of standard therapy, age

  • IFM: benefit of HSCT only in < 60 y/o

  • Single HDT with SCT with Mel alone( without TBI )should be considered a standard of care in young patient

Attal Hematology 2007, Fermand ASCO 2008

Role of sct in mm1
Role of SCT in MM

  • Asymptomatic( smoldering ) MM should not be treated until signs of progression

  • Stem cell should be harvested within 3-6 months after therapy initiation

  • Timing of autotransplantation has no effect on overall survival

  • MAG 90, similar overall survival in patients who received SCT as first line or rescue in parimary resistance to standard Tx or at relapse in responder

Attal Hematology 2007, Fermand ASCO 2008

Role of sct in mm2
Role of SCT in MM

  • Average time without Sx, Tx, and Tx toxicity favor upfront SCT

  • Present recommendation for early SCT is mainly based on quality of life

  • Single vs double trials did not provide evidence for a benefit sufficient enough to overcome the risks and constraints of using tandem transplantation

  • Double transplantation proposed to patients failing to achieve a VGPR after first SCT, ideally as part of clinical trial

Attal Hematology 2007, Fermand ASCO 2008

Role of sct in mm3
Role of SCT in MM

  • Thalidomide, bortezomib or lenalidomide including regimens may be preferred to VAD-like regimen as induction therapy

Attal Hematology 2007, Fermand ASCO 2008

Allogeneic sct in mm
Allogeneic SCT in MM

  • High TRM with myeloablative regimen

  • Reduced transplantation-related toxicity with GVM in reduced intensity conditioning

  • Heavily pretreated patients and progressive disease( advanced MM ) do not appear benefit with RIC

  • Tandem auto-RIC allogeneic SCT, encouraging in prospective clinical trials

Attal Hematology 2007, Fermand ASCO 2008
