Article: Randomized phase II trial of first-line treatment with tailored irinotecan and S-1 therapy versus S-1 monotherapy for advanced or recurrent gastric carcinoma (JFMC31-0301).
[show abstract] [hide abstract]
ABSTRACT: The pharmacokinetics of irinotecan vary markedly between individuals. This study sought to compare tailored irinotecan and S-1 therapy with S-1 monotherapy for the treatment of patients with advanced/recurrent gastric cancer. Patients with advanced/recurrent gastric cancer were randomized to receive tailored irinotecan and S-1 (arm A) therapy or S-1 therapy alone (arm B). Arm A received S-1 (80-120 mg/m(2)/day) for 14 days, with irinotecan on days 1 and 15. The initial irinotecan dose of 75 mg/m(2) (level 0) was adjusted for toxicity during an earlier course. In arm B, S-1 (80-120 mg/day) was administered alone for 28 days, followed by 14 days without therapy. Ninety-five patients were randomized (48 patients to arm A and 47 patients to arm B). The response rate of the primary tumor (Japanese criteria) was 25.0% in arm A (12 of 48 patients) and 14.9% in arm B (seven of 47 patients), whereas the response rates according to Response Evaluation Criteria In Solid Tumors were 27.8% (10 of 36) versus 21.9% (seven of 32). Hematological toxicity, anorexia, and diarrhea were significantly more common in arm A, but both arms had similar grades 3-4 toxicities. These findings suggest the usefulness of tailored irinotecan and S-1 therapy for gastric cancer.Anti-cancer drugs 07/2011; 22(6):576-83. · 2.23 Impact Factor -
Article: [Repetition of Helicobacter cinaedi infections during chemotherapy for malignant lymphoma].
[show abstract] [hide abstract]
ABSTRACT: A 70-year-old male, who had undergone resection of gastric malignant lymphoma in 1992, presented with cervical lymph node swelling in January 2008. Pathological examination of the lymph node biopsy demonstrated recurrence of malignant lymphoma, and he was treated with the R-CHOP regimen. Although he did not develop fever during the first through third course of R-CHOP, from the fourth course, he repeatedly demonstrated fever over 38°C for about one week after each course of chemotherapy, despite the absence of neutropenia. Helicobacter cinaedi infection was confirmed by blood culture each time. Although it is difficult to diagnose Helicobacter cinaedi infection by the standard culture method, increased numbers of recent reports especially in immunocompromised patients have emphasized the importance of diagnosing Helicobacter cinaedi infection.[Rinshō ketsueki] The Japanese journal of clinical hematology 12/2010; 51(12):1781-5. -
Article: POEMS syndrome complicated by follicular lymphoma.
[show abstract] [hide abstract]
ABSTRACT: A 59-year-old woman presented with ascites and intraperitoneal lymph node swelling. Pathological examination of the lymph node revealed follicular lymphoma. After a lymph node biopsy, she developed atypical genital bleeding, multiple endocrine disorders, polyneuropathy with a high plasma level of vascular endothelial growth factor (VEGF), and was diagnosed with POEMS syndrome. Following administration of methyl prednisolone, ascites immediately decreased and her performance status improved; however, about 18 months later, renal failure occurred, and she died despite increased steroid dosage. Lymph node swelling is often found in POEMS syndrome; however, its histological appearance is not well known, and it is very rare to be concomitant with malignant lymphoma. Therefore, it is important to perform a lymph node biopsy and investigate it in relation with VEGF.[Rinshō ketsueki] The Japanese journal of clinical hematology 11/2009; 50(11):1621-5. -

Article: Removal of mucus for ultrastructural observation of the surface of human gastric epithelium using pronase.
[show abstract] [hide abstract]
ABSTRACT: Helicobacter pylori adhering to the human gastric epithelium causes gastric diseases such as ulcer, carcinoma and lymphoma. It is thus important to observe in detail both the surface of the epithelial cells and the H. pylori that adhered to it for the elucidation of H. pylori-induced diseases by scanning electron microscopy (SEM). Since the thick mucus layer blocks the observation of the cell surface and the bacteria, it is generally eliminated during the processing for SEM by roughly mechanical methods, but these treatments also demolish the ultrastructure of the cells. We studied the nonmechanical method for removal of mucus layer of gastric epithelium using pronase. To determine the optimal concentration of pronase, mucin was used as a substrate for inhibition of the viscosity. Pronase was added in 2% mucin at the concentration of 10, 50, 100, 500, 1000, 2000 or 5000 unit/ml and the flowing time of the mixture was measured. Based on the digestion experiment, biopsied specimens from 24 patients with dyspepsic symptoms were fixed in glutaraldehyde and then washed in rolling with different concentration of pronase. After the pretreatment by pronase, the specimens were treated according to the standard process for SEM. We succeeded in removing the mucus layer on the surface of epithelial cells from the biopsied specimens fixed in glutaraldehyde by rinsing with 2000 unit/ml pronase for 24 hours. Using our digestive method without destroying the ultrastructure, the earliest stage which H. pylori has adhered onto the human gastric epithelium can be observed for the investigation of H. pylori-induced gastric disorders by SEM.Helicobacter 05/2002; 7(2):112-5. · 3.15 Impact Factor -
