　View Summary

We report a chronic myeloproliferative disease-unclassifiable (CMPD-U) patient who achieved hematological remission following imatinib mesylate (imatinib). Chromosomal and molecular analyses demonstrated no genetic abnormalities of c-abl, bcr-abl, c-kit or platelet-derived growth factor receptor (PDGFR) genes from hematopoietic cells. Although there has been one report of CMPD-U patient with chromosomal abnormalities of the PDGFR gene having complete hematologic responses upon treatment with imatinib, there have not been similar reports of patients without chromosomal abnormalities. This is the first case report of a CMPD-U patient with no chromosomal abnormalities who completely responded to treatment with imatinib.

The patient was treated with prednisolone and responded favorably. We demonstrated that anti-platelet (PLT) antibody of the patient was IgG4 and that it may react with HLA, not specific antigen, on both pancreas and PLT.

　View Summary

Purpose: To determine the recommended dose (RD) of cis-diammine-glycolatoplatinum (nedaplatin) when given concurrently with 5-FU and high dose radiation therapy in the treatment of esophageal cancer. The purpose of the phase II trial is to determine efficacy and further define the side effect profile. Methods: Twenty-six patients with clinical stage I to IVA squamous cell carcinoma of the esophagus were enrolled in a non-surgical treatment comprised of a fixed dose of fluorouracil (400 mg/m(2) administered as continuous intravenous infusion on days 1-5 and days 8-12) plus escalating doses of nedaplatin (40 mg/m(2) in level 1, 50 mg/m(2) in level 2, or 60 mg/m(2) in level 3 on days 1 and 8), repeated twice every 3 weeks with concurrent radiotherapy (60 Gy). Results: Between July 1998 and February 2004, a total of 26 patients entered this trial, all of whom were considered evaluable for toxicity assessment. In phase I of the study, 12 patients were treated in sequential cohorts of three to six patients per dose level. The maximum tolerated dose was reached at level 3 with two grade 4 neutropenia and one grade 4 thrombocytopenia. Thus, the recommended dosing schedule is level 2. Of the 20 patients treated at the RD level 2, including 6 patients of the RD phase I portion, 8 out of 20 patients (40%) had grade 3-4 neutropenia, 5 patients (25.0%) had grade 3-4 thrombocytopenia, 4 patients (20.0%) had grade 3 anemia and 4 patients (20.0%) had grade 3-4 esophagitis. Other toxicities were relatively mild and usually of grade 2 or less. Objective responses were noted in the 26 patients (overall response rate, 88.5%) including 11 (42.3%) complete remissions. The 1- and 3-year survival rates were 65.1 and 37.2%, respectively, with a median survival time of 21.2 months. Conclusions: The combination of nedaplatin and 5-FU with radiation is a feasible regimen that shows promising antitumor activity with an acceptable safety profile in patients with esophageal cancer.

　View Summary

A 31-year-old man referred to our hospital for treatment of his chronic myeloid leukemia (CML) in the first chronic phase by bone marrow transplantation. We pretreated him with cyclophosphamide and total body irradiation and bone marrow transplantation (BMT) was carried out. On day 31, the engraftment was confirmed and on day 52, acute graft versus host disease (GVHD) was observed. On day 189, he lost consciousness due to cyclosporine A-induced leukoencephalopathy and 375 mg cyclosporine A was changed to 100 mg prednisolone. On day 199, liver dysfunction (AST 410 IU/L, ALT 557 IU/L, gamma GTP 385 IU/L, ALP 363 IU/L, D-Bil 0.3 mg/dl) developed and a liver biopsy was performed. PCR analysis of DNA from the liver biopsy specimen was positive for HHV-6 and immunostaining using anti-HHV-6 and anti-HHV-6b antibodies showed positive staining in the cytosol of hepatocytes. No other viruses were found to induce hepatitis. From these results, he was diagnosed as having HHV-6 hepatitis and it was successfully treated with gancyclovir (GCV) administration.

　View Summary

We report a patient with adult T-cell lymphoma who developed acute myeloid leukemia (AML) after allogeneic cord blood transplantation (CBT). Fluorescence in situ hybridization (FISH) studies and molecular analysis using short tandem repeat (STR) sequences proved the AML to be of donor origin. Although 25 cases of donor cell leukemia (DCL) occurring after allogeneic bone marrow transplantation have previously been reported, there have been no reports of DCL after CBT. This case is the first-reported DCL patient after CBT.

　View Summary

Here we report a case of myelodysplastic syndrome (MDS) with myelofibrosis associated with Bowen's disease. A female patient had undergone an operation and chemotherapy for ovarian cancer when she was 65 years old, and she developed MDS at the age of 70 years old. PCR-single strand conformation polymorphism (SSCP) analysis of peripheral blood mononuclear cells, a Bowen's disease lesion, and normal skin showed an abnormal peak in TP53 exon5. Direct sequencing revealed that they all had missense mutation in codon 175 (G to A) of arginine switched to histidine, suggesting a germline mutation of TP53. It was speculated that p53 function was lost by TP53 germline mutation with the loss of a wild type allele induced by the chemotherapy against ovarian cancer, leading to the development of MDS. No therapeutic effects of low dose melphalan or cyclosporine A on MDS were observed, however one month of 30 mg/day prednisolone administration induced a hematological response.

　View Summary

One of the most common complications related to endoscopic mucosal resection is hemorrhage; in almost every case, the bleeding is endoscopically managed, but some cases are unresponsive to the treatment. We have encountered three cases of endoscopically uncontrollable lower gastrointestinal hemorrhage after endoscopic mucosal resection in the colon which we successfully treated by urgent superselective transcatheter embolization. In our three cases, massive hemorrhage occurred immediately after endoscopic mucosal resection of a sessile polyp 25-40mm in diameter, two cases in the ascending colon and one in the rectum. Although hemoclip placement was attempted in every case, hemostasis was not achieved. Emergency angiography disclosed massive extravasation of the contrast material in the colon. Hemostasis was achieved immediately after superselective transcatheter arterial embolizations with microcoils, with no observable ischemic complications and without the need of transfusions. In conclusion, superselective transcatheter embolization with microcoils should be considered a safe and efficient treatment option for endoscopically uncontrollable lower gastrointestinal hemorrhage occurring after endoscopic mucosal resection.

　View Summary

Most cases of cholangiocarcinoma have reached an unresectable stage by the time they are discovered despite significant progress of diagnostic modalities, Many of these patients with obstructive jaundice are often treated by biliary drainage using stents to relieve the jaundice. However, the stent patency period is as short as 3 to 9 months because of tumor ingrowth or overgrowth, and mean survival is at most 12 months. Therefore, both continuous relief of obstructive jaundice and local control of the tumor are required in the treatment for advanced cholangiocarcinoma. In this investigation, we developed a new percutaneous transhepatic biliary drainage tube coated with carboplatin (carboplatin-coated tube; CCT). CCT continuously released a fixed amount of carboplatin for 4 weeks and showed an antitumor effect on human cholangiocarcinoma cell line HuCC-T1 in vitro, When CCT was embedded in subcutaneous tumor inoculated in nude mice, a significant reduction of tumor size with no apparent damage to normal adjacent tissue was observed. On the basis of these studies, 5 patients with inoperable cholangiocarcinoma were treated with CCT for 4 weeks. Overall efficacy rate of 5 patients with cholangiocarcinoma was 60% (partial response in 3 and no change in 2), No apparent side effect was observed in these patients. Thus, CCT may provide a new treatment modality for this disease. Randomized controlled trials comparing CCT therapy with palliative stenting are required to confirm these results.
