- Purpose Systemic peripheral T-cell lymphomas (PTCLs) respond poorly to conventional therapy. To evaluate the efficacy of a dose-dense approach consolidated by up-front high-dose chemotherapy (HDT) and autologous stem-cell transplantation (ASCT) in PTCL, the Nordic Lymphoma Group (NLG) conducted a large prospective phase II study in untreated systemic PTCL. This is the final report, with a 5-year median follow-up, of the NLG-T-01 study. Patients and Methods Treatment-naive patients with PTCL age 18 to 67 years (median, 57 years) were included. Anaplastic lymphoma kinase (ALK) -positive anaplastic large-cell lymphoma (ALCL) was excluded. An induction regimen of six cycles of biweekly CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone) was administered (in patients age > 60 years, etoposide was omitted). If in complete or partial remission, patients proceeded to consolidation with HDT/ASCT. Results Of 166 enrolled patients, 160 had histopathologically confirmed PTCL. The majority presented with advanced-stage disease, B symptoms, and elevated serum lactate dehydrogenase. A total of 115 underwent HDT/ASCT, with 90 in complete remission at 3 months post-transplantation. Early failures occurred in 26%. Treatment-related mortality was 4%. At 60.5 months of median follow-up, 83 patients were alive. Consolidated 5-year overall and progression-free survival (PFS) were 51% (95% CI, 43% to 59%) and 44% (95% CI, 36% to 52%), respectively. Best results were obtained in ALK-negative ALCL. Conclusion Dose-dense induction followed by HDT/ASCT was well tolerated and led to long-term PFS in 44% of treatment-naive patients with PTCL. This represents an encouraging outcome, particularly considering the high median age and adverse risk profile of the study population. Therefore, dose-dense induction and HDT/ASCT are a rational up-front strategy in transplantation-eligible patients with PTCL. J Clin Oncol 30: 3093-3099.

- The main objective of the MCL3 study was to improve outcome for patients not in CR before transplant by adding (90)Y-ibritumomab-tiuxetan (Zevalin) to the high-dose regimen. 160 consecutive, untreated stage II-IV MCL patients < 66 years received rituximab (R)- maxi-CHOP alternating with R-high-dose Ara-C (6 cycles total), followed by high-dose BEAM or BEAC and autologous stem cell transplantation 2005-2009. Zevalin (0.4 mCi/kg) was given to responders in only CRu/PR prior to high-dose therapy. The overall response rate (ORR) pre-transplant was 97%. After a median follow-up of 4.4 years the outcome did not differ from that of the historic control, the MCL2 trial with the same treatment except for Zevalin. Overall (OS), event free (EFS), and progression-free survival (PFS) at 4 years were 78, 62 and 71%, respectively. For patients in CRu/PR before transplant who received Zevalin duration of response was shorter than in the CR group. Inferior PFS, EFS- and OS were predicted by PET-positivity pre-transplant and detectable minimal residual disease (MRD) before and after transplant. In conclusion, a positive PET prior to transplant and MRD are strong predictors of outcome. Late intensification with Zevalin may be too late to improve the outcome of patients not in CR before transplant.

- Patients and Methods: From May 2007 to October 2010, 66 newly diagnosed primary central nervous system lymphoma (PCNSL) patients (M/F ratio 1:1) were enrolled. Younger patients (≤65 yrs; N=39) received 6 three-weekly cycles of chemotherapy consisting of: high-dose (HD)-methotrexate (MTX) (cycles 1, 2, 4 and 5), HD-cytosine arabinoside (AraC) (cycles 3 and 6) in addition to Rituximab (cycle 1 only), ifosfamide (cycles 1 and 4), cyclophosphamide (cycles 2 and 5), vincristine (cycles 2 and 5), vindesine (cycles 3 and 6), and dexamethasone (all 6 cycles). Depocyte® was delivered intratechally during the HD-MTX cycles. Elderly patients (66-75 yrs; N=27) received an identical Rituximab-containing 1st cycle. Cyclophosphamide and ifosfamide were replaced by temozolamide (cycles 2 to 6), which was also given as maintenance in patients with chemosensitive disease, and vincristine was omitted. No radiotherapy was given. Response was determined after the 2nd, 4th and 6thchemotherapy cycle by cerebral MRI and assessed according to International Primary CNS Lymphoma Coordinating Group criteria. The primary endpoint was overall survival (OS), secondary endpoints were progression-free survival (PFS), overall response rate (ORR), systemic toxicity and neurotoxicity assessed as Mini Mental State Examination (MMSE) and Functional Independence Measure (FIM). Results: The median age was 64 yrs overall, 55 yrs (range 40-65) for younger and 70 yrs (range 66-75 years) for elderly patients. In 56 patients, the International Extranodal Lymphoma Study Group prognostic score was: 0-1 (N=5), 2-3 (N=36) and 4-5 (N=15). In the remaining 10 patients, lumbar puncture was not performed in five and spinal fluid protein concentration not reported in additional five cases. Response assessment after completion of induction treatment was performed in 43 out of 66 patients and showed complete remission (CR/CRu) in 30 patients, partial remission (PR) in 5 and progressive disease (PD) in 8. The ORR was 53 %. In 23 patients, response could not be evaluated due to early progression (n=8), toxic death (n=4), poor performance (n=3), neurotoxicity (n=5), or other causes (n=3). Of the 27 elderly patients, 15 continued to maintenance therapy. Of these, 14 have completed the maintenance schedule. Remission status at month 3 was CR in 13 and PD in 1 patient. With a median follow-up of 11.1 months (range 0.6-40.2) the 3-yr OS was 54.6% with no significant difference between younger and elderly patients (56.4% vs 51.9% respectively, p=0.32). The 3-yr PFS was 35.1% (32.9% in younger and 38.2 % in elderly patients; p=0.96). There were four septic deaths. Grade 3-4 hematological toxicity was seen in 79 % of the patients. Arachnoditis-like symptoms occurred in 13 patients. In all but two patients, the symptoms resolved within less than a week. MMSE and FIM were recorded both before and after therapy in 32 patients. Scores improved in 18 and 20 patients, respectively. Conclusion: In conclusion, the schedule applied in the present study led to a 3 yr PFS of 35%. Surprisingly, no significant outcome difference was found between the younger and the elderly patients. The majority of treatment failures were due to early progressive disease under induction therapy. Although the follow-up of our study is short, de-escalation of induction treatment intensity by introduction of a less toxic agent as temozolomide, and its subsequent use in a maintenance schedule may explain a possible survival benefit of this strategy in elderly patients. Disclosures: No relevant conflicts of interest to declare.
