PRIMARY OBJECTIVES:
I. To compare event-free survival (EFS) in patients with newly diagnosed T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LLy) who are randomized to a modified augmented Berlin-Frankfurt-Munster (ABFM) backbone versus bortezomib plus the modified ABFM backbone.
SECONDARY OBJECTIVES:
I. To determine the safety and feasibility of modifying standard therapy for T-ALL and T-LLy based on the results of UKALL 2003, which includes a dexamethasone-based induction, additional doses of pegaspargase (PEG-ASP) during induction and delayed intensification (DI), and dexamethasone pulses during maintenance therapy.
II. To determine if prophylactic (presymptomatic) cranial radiation therapy (CRT) can be safely and effectively eliminated in the 85-90% of T-ALL patients classified as standard or intermediate risk.
III. To determine the proportion of end of consolidation (EOC) minimal residual disease (MRD) \>= 0.1% T-ALL patients who become MRD negative (undetectable by flow cytometry) after intensification of chemotherapy, using three high risk (HR) BFM blocks, and to compare EFS between the patients who become MRD negative after the three HR BFM blocks and continue on chemotherapy with those who continue to have detectable MRD and are eligible for other treatment strategies, including hematopoietic stem cell transplant (HSCT).
IV. To compare the EFS between very high risk (induction failure) T-LLy patients treated with HR BFM intensification blocks who have partial or complete response (PR or CR) with those who do not respond (NR).
CORRELATIVE OBJECTIVES:
I. To investigate the prognostic significance of day 29 bone marrow (BM) MRD in T-LLy patients.
II. To determine if protein expression patterns can predict bortezomib response and drug resistance in T-ALL.
III. To analyze and target relevant signaling pathways in T-ALL blasts, focusing on early T cell precursor (ETP) acute lymphoblastic leukemia (ALL).
OUTLINE: Patients are randomized to 1 of 2 treatment arms. Patients are risk assigned based on data from end of induction and/or consolidation therapy; this then modifies the subsequent therapy received.
T-ALL Risk Group Definitions:
Standard Risk (SR): CNS1\*, lumbar puncture prior to steroid therapy (not steroid pretreated), Day 29 (end of induction) bone marrow M1, Day 29 bone marrow minimal residual disease (MRD) \<=0.01%, no testicular leukemia at diagnosis.
Intermediate Risk (IR): Not SR or VHR.
Very High Risk (VHR): M3 marrow at Day 29 and/or end of consolidation (EOC) MRD \>=0.1%.
\*CNS2 and CNS3 cannot be SR and are assigned to IR or VHR based on marrow response.
T-LL Risk Group Definitions:
Standard Risk (SR): CNS1\*, MRD at diagnosis \<1% in bone marrow, lumbar puncture prior to steroid therapy (not steroid pretreated), Day 29 (end of induction) complete response (CR) or partial response (PR).
Intermediate Risk (IR): Not SR or VHR.
Very High Risk (VHR): Stable Disease (SD)/No response (NR) at Day 29 (End of Induction).
\*CNS2 and CNS3 cannot be SR and are assigned to IR or VHR based on radiographic response.

Inclusion Criteria:
- T-ALL: T-ALL patients must be enrolled on AALL08B1 or Project:EveryChild (APEC14B1, if
open for the classification of ALL patients) prior to treatment and enrollment on
AALL1231
- All patients must be > 1 and < 31 years of age
- Patients must have newly diagnosed T-lymphoblastic leukemia (T-ALL) or T-lymphoblastic
lymphoma (T-LLy) stages II-IV
- Note: a diagnosis of T-ALL is established when leukemic blasts lack
myeloperoxidase or evidence of B-lineage derivation (cluster of differentiation
[CD]19/CD22/CD20), and express either surface or cytoplasmic CD3 or two or more
of the antigens CD8, CD7, CD5, CD4, CD2 or CD1a, and are present either in
peripheral blood or > 25% in the bone marrow; if surface CD3 is expressed on all
leukemic cells, additional markers of immaturity, including terminal
deoxynucleotidyl transferase (TdT), CD34 or CD99 will be assessed for expression;
cases with uncertain expression will receive additional review within the
appropriate Children's Oncology Group (COG) reference laboratory
- For T-LLy patients with tissue available for flow cytometry, the criterion for
diagnosis should be analogous to T-ALL; for tissue processed by other means (i.e.
paraffin blocks), the methodology and criteria for immunophenotypic analysis to
establish the diagnosis of T-LLy defined by the submitting institution will be
accepted
- All patients and/or their parents or legal guardians must sign a written informed
consent; assent, when appropriate, will be obtained according to institutional
guidelines

in the 7 days prior to initiating induction chemotherapy or for =< 336 hours (14
days) in the 28 days prior to initiating induction chemotherapy; prior exposure
to ANY steroids that occurred > 28 days before the initiation of protocol therapy
does not affect eligibility; the dose of prednisone or methylprednisolone does
not affect eligibility

obtained prior to administration of any systemic or intrathecal chemotherapy,
except for steroid pretreatment) system chemotherapy must begin with 72 hours of
this IT therapy; or
- Pretreatment with hydroxyurea; or
- 600 cGy of chest irradiation, if medically necessary

inhalation steroids and topical steroids are not considered pretreatment
- Pre-existing >= grade 2 sensory or motor peripheral neurotoxicity
- Uncontrolled seizure disorder
- Diagnosis of Down syndrome (Trisomy 21)
- Patients who are pregnant since fetal toxicities and teratogenic effects have been
