Description

Patients are in 2 cohorts: Cohort 1: dexamethasone, methotrexate, ifosfamide, pegaspargase, and etoposide (modified SMILE) chemotherapy regimen alone and pembrolizumab in children, adolescents, and young adults with advanced stage NK lymphoma and leukemia Cohort 2: combining pralatrexate (PRX) (Cycles 1, 2, 4, 6) and brentuximab vedotin (BV) (Cycles 3, 5) to cyclophosphamide, doxorubicin, and prednisone in children, adolescent, and young adults with advanced peripheral T-cell lymphoma (non-anaplastic large cell lymphoma or non-NK lymphoma/leukemia) . Both groups proceed to allogeneic stem cell transplant with disease response.

Eligibility criteria

Inclusion Criteria: * Patients must weigh at least 10 kilograms at the time of the study enrollment. * Diagnosis Newly diagnosed patients with histologically proven mature T- and NK- cell neoplasms: COHORT 1 * Aggressive NK cell leukemia (ICD-O code 9948/3) * Extranodal NK/T-cell lymphoma, nasal type (ICD-O code 9719/3) COHORT 2 * Enteropathy-associated T-cell lymphoma (ICD-O code 9717/3) * Hepatosplenic T-cell lymphoma (ICD-O code 9716/3) * Peripheral T-cell lymphoma, non-otherwise specified (ICD-O code 9702/3) * Angioimmunoblastic T-cell lymphoma (ICD-O code 9705/3) * Other mature T- and NK-cell neoplasm histologies will considered after case-by-case discussion with Study Chairs and executive Vice-Chair Patients with lymphoma must have stage III or IV disease (See Appendix III for Staging). * Organ Function Requirements Adequate liver function defined as: * Total bilirubin ≤ 1.5 x upper limit of normal (ULN) for age. * ALT (SGPT) \< 3 x ULN for age. Adequate cardiac function defined as: * Shortening fraction of ≥ 27% by echocardiogram, or * Ejection fraction of ≥ 50% by radionuclide angiogram. Adequate pulmonary function defined as: • Patients with a history of pulmonary dysfunction must have no evidence of dyspnea at rest, no exercise intolerance due to pulmonary insufficiency, and a pulse oximetry \> 92% while breathing room air unless current dysfunction is due to the lymphoma, in which case the patient is eligible.
