A case of aggressive myeloma recognized shortly after the remission following high-dose chemotherapy with autologous peripheral blood stem cell transplantation.

A 45-year-old woman was referred to our hospital with acute renal failure and pyrexia. In August 2005, the patient was diagnosed with IgA-λ type multiple myeloma with chromosome 13 deletion, and received three cycles of vinclistine, adriamycin and dexamethasone followed by high-dose melphalan-based autologous peripheral stem cell transplantation: this resulted in remission 2 months before admission to our hospital. Serum IgA concentration was within the normal limit, but an excess of myeloma cells in bone marrow was confirmed.

A case of treatment-related myelodysplastic syndrome spontaneously resolved by drug discontinuance.

Although great advancements have been witnessed in treatment results for hematopoietic tumors in recent years, development of secondary malignant tumors induced by anti-cancer drugs still remains a serious issue. We experienced a case of secondary myelodysplastic syndrome (MDS), possibly induced by cyclophosphamide (CY), which was spontaneously resolved by discontinuance of CY. A 24-year-old woman was diagnosed with follicular lymphoma in January 1998: she had developed bulky intra-abdominal lymphadenopathy, with repeated relapse and remission by several chemotherapy treatments.

Effect of L-asparaginase combined with vincristine and prednisolone on acute myeloblastic leukemia (M0) associated with non-Hodgkin lymphoma.

A 66-year-old Japanese woman was referred to us because of severe anemia and fever and presented at our hospital. She was eventually diagnosed as having acute myeloblastic leukemia (AML; M0) with non-Hodgkin lymphoma (NHL). We investigated the therapeutic efficacy of L-asparaginase (L-Asp), vincristine and prednisolone for both her AML and NHL.

Treatment of high-risk peripheral T-cell lymphomas other than anaplastic large-cell lymphoma with a dose-intensified CHOP regimen followed by high-dose chemotherapy. A single institution study.

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.

[Pharmacokinetics of S-1].

S-1 is an attractive oral fluorouracil antitumor drug, which is being called "a self-rescuing drug". This novel oral fluoropyrimidine is combined with three pharmacological agents: tegafur (FT) which is a prodrug of 5-fluorouracil (5-FU), 5-chloro-2,4-dihydroxypyridine (CDHP) which inhibits dihydropyrimidine dehydrogenase (DPD) activity, and potassium oxonate (Oxo) which reduces gastrointestinal toxicity. Phase I and an early phase II clinical trials were performed about ten years ago, and these results had already been introduced to the Journal "Clinical Cancer Research Vol.
