RESUMEN
Patients with aggressive non-Hodgkin's lymphoma (NHL) showing several risk factors have a poor prognosis. In such patients, conventional chemotherapy results in a low complete response rate and a high relapse rate. We performed a prospective trial of intensive induction chemotherapy followed by high-dose consolidation therapy to determine the feasibility of such an approach. We treated 39 patients with aggressive poor risk NHL with double-CHOP (D-CHOP) chemotherapy followed by high-dose therapy (HDT) with or without peripheral blood stem cell transfusion (PBSCT). The median age of the patients was 54 years (range 17-65). Twenty-seven were considered to be at high (H) and 12 were at high-intermediate (H-I) risk according to the age-adjusted International Prognostic Index. Thirty-four patients (87%) responded (complete response: 74%, partial response: 13%) to D-CHOP chemotherapy. Of the 34 responders, 24 received HDT followed by PBSCT, 7 received high-dose methotrexate, and 3 refused consolidation therapy. At a median follow-up period of 26 months, the estimated 3-year overall survival rate and event-free survival rate was 64 and 51%, respectively. Our data suggest that dose-intensified D-CHOP followed by consolidation HDT is safe and appears efficacious in aggressive NHL patients with H-I and H risk.

A 52-year-old woman was admitted to the gynecological department of our hospital on July 29, 2002 because of a right lower abdominal mass. She has been suffering from pain in the right leg and inguinal area for a month before coming to the hospital. She was found to have pancytopenia and high serum levels of LDH and IgD. A bone marrow examination showed 63.8% of plasma cells and serum immunoelectrophoresis showed M-protein of the IgD-lambda type. She was diagnosed as having multiple myeloma and transferred to our department. VAD therapy was started from August 22. Although the plasma cells in the bone marrow almost disappeared, the right lower abdominal mass remained and a new mass appeared on the right frontal chest wall after two courses of the treatment. Combination chemotherapy with vincristine, ranimustine, melphalan, and dexamethasone (ROAD) was started on November 1. This was followed with thalidomide and radiation therapy of the right inguinal region was added. On December 16th, she suddenly experienced speech disturbance, nausea and the disturbance of consciousness. Examination of her cerebrospinal fluid showed 368/microl mononuclear cells with 93% plasma cells. The plasma cells disappeared after the 6th intrathecal injection with MTX and prednisolone and the chemotherapy was resumed. One month later, CNS relapse was apparent followed by generalized spread of the tumor mass, and she died on March 17, 2003.

We investigated the efficacy of a dose-intensified double-CHOP regimen followed by high-dose chemotherapy with or without peripheral blood stem cell transplantation (PBSCT) in 11 patients with four types of peripheral T-cell lymphoma (PTCL). Three of the 4 patients with unspecified PTCL (PTCLu) achieved complete response (CR); 1 patient relapsed and 1 died of secondary leukemia after consolidation therapy. All angioimmunoblastic T-cell lymphoma (AILT) and subcutaneous panniculitis-like T-cell lymphoma (SPTCL) patients achieved CR; 5 of 6 have remained disease free for more than 3 years. The patient with hepatosplenic lymphoma did not achieve CR even after PBSCT and underwent allogenic bone marrow transplantation (allo-BMT). Thus, our regimen appears to be effective for high-risk AILT and SPTCL. However, allo-BMT should be considered for high-risk of PTCLu and hepatosplenic T-cell lymphoma.
