Ninety-seven patients with aggressive malignant lymphoma (ML) were treated with an intensive and sequential chemotherapy (protocol LNH-80). There were 42 patients with intermediate grade ML, 53 patients with high-grade ML, and two patients with true histiocytic ML. Most of the patients were in advanced stage: 21 stage III and 61 stage IV. The LNH-80 protocol schedule comprised three phases: (1) induction with three courses of an intensified CHOP-Bleo (cyclophosphamide, doxorubicin, vindesine, methylprednisolone, and bleomycin); (2) consolidation with cytarabine, followed by high-dose methotrexate and folinic acid rescue, then asparaginase; and (3) final intensification with two courses of CVAP-Bleo (cyclophosphamide, teniposide, cytarabine, methylprednisolone, and bleomycin). CNS prophylaxis included one injection of methotrexate during each induction course and the drugs of the consolidation phase. In cases of initial CNS localization, cranial radiotherapy was added. Eighty-four patients (87%) went into complete remission (CR), 18 (21%) of whom relapsed, usually during the phase of treatment or within 6 months of completing chemotherapy. Sixty-three patients are alive with an overall median follow-up of 24 months. The median survival time and the median disease-free survival have not been reached, and the survival curve seems to have plateaued at above 60%. There was no statistical difference between intermediate-grade ML (CR 90%, relapse 18%) and high-grade ML (CR 84%, relapse 24%). The toxicity of this treatment is mainly encountered during the induction phase: almost all patients had short-term neutropenia, less than 0.500 g/L in 57, with a documented infection in 25. Overall treatment-related mortality was 6%, with four patients dying during the induction phase.

Poikiloderma with neutropenia (PN, Clericuzio-type poikiloderma with neutropenia) is a rare autosomal recessive disorder caused by biallelic mutations in the USB1 gene (Alias C16orf57 and MPN1). To date, there have been only 37 reported cases worldwide of this disorder that presents with neutropenia, early onset poikiloderma, respiratory infections, palmo-plantar hyperkeratosis, and skeletal defects. Here we described the generation of human induced pluripotent stem cell lines (PN1 and PN2) from the peripheral blood of a 1-year-old patient using the dox-inducible STEMCCA vector. This patient presented with bacteremia, pneumonia, and neutropenia. Analysis of bone marrow demonstrated normal cellularity with trilineage hematopoiesis and neutropenia.
