Treatment Guidelines for PTCL: SFll CHOP Based
NCCN. Clinical practice guidelines in oncology: non-Hodgkin’s lymphoma. v.1.2013.
First-‐line Therapy
Clinical trial (preferred) ALCL, ALK+ histology • CHOP-‐21 • CHOEP-‐21
Other histologies (ALCL, ALK-‐; PTCL-‐NOS; AITL; EATL), regimens that can be used include: • CHOEP • CHOP-‐14 • CHOP-‐21 • CHOP followed by ICE • CHOP followed by IVE, alternaNng with intermediate-‐dose methotrexate (Newcastle regimen)
• Dose-‐adjusted EPOCH • HyperCVAD, alternaNng with high-‐dose methotrexate and cytarabine
First-‐line ConsolidaNon
All paNents except low risk (aaIPI) should be considered for high-‐dose therapy and stem cell rescue; ALCL, ALK+ is a subtype with good prognosis and does not need consolidaNve transplant if in remission
German High-‐Grade Lymphoma Study Group: T-‐Cell Lymphoma Cohort Analysis
• 320 paNents with mature nodal or extranodal T-‐cell or NK-‐cell lymphoma treated on 7 phase II or III studies (1993-‐2007)
• ALK posiNve: 78 paNents (24.4%) • ALK negaNve: 113 paNents (35.3%) • Treated with CHOP ± etoposide: 100%
• PaNents younger than 60 yrs of age with normal LDH • AddiNon of etoposide to CHOP improved 3-‐yr EFS: 75% vs 51% with CHOP alone (p = 0.003)

Brentuximab VedoUn in the Front-‐Line Treatment of PaUents With CD30+ Peripheral T-‐Cell Lymphomas: Results of a Phase I Study • 39 treatment-‐naive paNents with a diagnosis of CD30 +
PTCL (≥ 1% CD30 expression in malignant cells) • Two strategies for incorporaNng BV into treatment were examined:
• SequenUal treatment, in which sALCL paNents received 2 cycles of 1.8 mg/kg BV followed by 6 cycles standard-‐dose CHOP
• CombinaUon treatment, in which paNents with PTCL, including those with sALCL, received 6 cycles of BV in combinaNon with CHP (VincrisNn was omiled to eliminate the potenNal for addiNonal neurotoxicity).

Follow-up
Conclusions • There is a clear unmet clinical need for PTCL paNents
• Disease biology and classificaNon have to be improved • Long-‐term survival is poor (20 -‐25% with anthracyclin-‐based treatment)
• Current treatment guidelines are sNll CHOP-‐based
• Up-‐front autologous transplantaNon has improved PFS in responding paNents
• Ongoing studies invesNgate combinaNons with romidepsin and CHOP/CHOEP, or BV or Pralatrexate
New agents in relapsed/refractory PTCL
• The historical outcomes for paNents with relapsed disease have been especially dismal
• In a recent retrospecNve study on 153 paNents with relapsed or refractory PTCLs who did not undergo transplant , the reported median OS was only 5.5 months and the PFS 3.1 months (1)
• These data do not capture possible gains from novel agents, since paNents included in the study had been diagnosed prior to 2010, before the approval of the new drugs.
