[Long term results for intermediate and high grade localized non Hodgkin lymphoma, treated with chemotherapy and radiotherapy].

Background: Treatment of intermediate and high grade non-Hodgkin lymphoma (NHL) includes chemotherapy with or without radiotherapy, depending on the clinical stage. The standard treatment for advanced NHL is 8 cycles of combined chemotherapy, cyclophosphamide, adriamycin, vincristine and prednisone (CHOP). Patients presenting with localized disease are treated with fewer chemotherapy cycles and involved field radiotherapy, with good results.

[Natural killer cell leukemia. Case report].

Natural killer leukemia is a rare and highly aggressive neoplasm, is more common in young male patients and has a very poor prognosis, with a median survival of few weeks. We report a 17 years old male patient who developed, after an acute upper respiratory disease, a rapidly multiorganic failure with pancytopenia. Bone marrow aspiration and trephine biopsy showed an acute lymphoblastic leukemia.
