Program Goals
• Identify prognostic and clinical factors that
should be considered in selecting treatment
for patients with T-cell lymphoma.
• Consider patient- and disease-specific factors
when selecting frontline and
relapse/refractory treatment options for
patients with T-cell lymphoma.
• Assess how emerging therapies or regimens
for patients with T-cell lymphoma may impact
current treatment practices.
T-Cell Lymphoma
Overview
• Relatively rare
− ~10% of lymphomas in the United States
• PTCL
− Arises from mature T-cell counterparts
− Geographic variation in distribution
− Has 3 major aggressive subtypes
• PTCL-NOS (25.9%)
• AITL (18.5%)
• ALCL (ALK+[6.6%], ALK−[5.5%])
AITL = angioimmunoblastic T-cell lymphoma; ALCL = anaplastic large cell lymphoma; ALK =
anaplastic lymphoma kinase; NOS = not otherwise specified; PTCL = peripheral T-cell lymphoma.

PTCL-NOS
Clinicopathologic Features
• Clinically aggressive, typically occurs in adults
aged 50 to 70 years
− Usual patient presentation: high-stage disease,
generalized lymphadenopathy, B symptoms, and
peripheral blood eosinophilia
• Highly variable pathology
− Most likely represents more than 1 subtype
• Broad differential diagnosis due to the
heterogeneous appearance
− Other lymphoma subtypes
− Reactive hyperplasias due to viral or drug reaction
AITL
Clinicopathologic Features
• Clinically aggressive, typically occurs in middle-aged
or elderly adults
− Dismal outcome with current therapies
− Usual patient presentation: generalized lymphadenopathy,
fever, weight loss, skin rashes, arthritis, polyclonal
hypergammaglobulinemia, and hemolytic anemia
• Displays a characteristic arborizing vascular pattern
• Coexisting immune dysfunction may complicate
diagnosis.
• Differential diagnosis
− Other lymphoma subtypes
− Atypical immune reaction
− Hyperplasia (viral or idiopathic)
ALCL
Clinicopathologic Features
• Clinically aggressive with biphasic age
distribution
− Younger patients, generally ALK+
• Associated with improved survival compared with
other PTCL subtypes
− Older patients, more likely ALK−
• Not challenging to identify
− CD30 strongly expressed in all cases
− t(2;5)(p23;q25), prototypical translocation in ALK+
subtype
• Abnormal ALK-NPM fusion protein overexpressed
Case 1
PTCL-NOS
Case 1
Presentation, Biopsy, PET/CT Scan
• A 50-year-old man presented with fatigue
and lymphadenopathy.
• Biopsy showed PTCL-NOS.
• Patient underwent PET/CT scanning,
which showed
− Nodes in the axilla, periaortic region, and
iliac region; and
− An SUVmax of 9.
SUVmax = maximum standardized uptake value.
Case 1
Additional Findings
• His spleen was slightly enlarged with no
focal lesions.
• Results of a CBC were normal, except for
his platelet count, which was 135,000/mm3.
• Results of a bone marrow biopsy were
negative.
• Remaining results from the diagnostic
work-up were negative.

Case 1
Initial Treatment Considerations
• As a relatively young and fit patient, he
should be given aggressive therapy.
− Consider an etoposide-containing regimen.
• Consider ASCT as consolidation after
induction therapy.
• Always try to enroll a patient in clinical trial,
if possible.

Case 2
Presentation, Biopsy, PET/CT Scan
• A 41-year-old man presented with fever
38.5oC) and malaise and was found to have
a palpable right axillary node.
• A biopsy of the axillary node showed ALCL,
CD30+ and ALK−.
• Results of a bone marrow biopsy were
negative.
• He underwent PET/CT scanning, which
showed PET-avid enlarged nodes in the
chest and abdomen.

Case 2
Initial Treatment Considerations
• Given that it is stage III disease, ALCL,
ALK−, it should be approached as if it
were PTCL-NOS rather than ALCL,
ALK+.
• He is young and may tolerate the highdose combination very well.
− Treatment options include ACVBP* with
supportive G-CSF, CHOEP, or EPOCH.
• If he reaches CR → ASCT.
* Regimen not available in the United States.

Case 3
Initial Treatment Considerations
• Patients like this—older and not very well—often
respond early on to steroids.
− Start with a steroid-containing combination to try to get her
symptoms under control and improve her performance status.
• Avoid anthracycline-based therapy.
• Single-agent gemcitabine may help manage disease
without excess myelosuppression.
• Look for the possible presence of an associated B-cell
clone; if found, use a rituximab combination.
• This is one of the more difficult patient types.
• If possible, enroll the patient in clinical trial!

Role of Transplant
Concluding Remarks
• The key to getting a better understanding
of these rare lymphoma subtypes and to
improving patient outcomes lies in a
collaborative effort and efficient enrollment
of patients into clinical trials.
• We also need more biologic studies to
discern and understand clinicopathologic
features of various PTCL subtypes better.
