Efficacy and Safety of FOLFIRI Regimen in Elderly Versus Nonelderly Patients with Metastatic Colorectal or Gastric Cancer.

Background: Irinotecan-based chemotherapy is a standard backbone of therapy in patients with metastatic colorectal cancer (CRC) or gastric cancer (GC). However, there is still a paucity of information concerning the efficacy and safety of irinotecan-based regimens in elderly patients.

Patients And Methods: Using the patient cohort ( = 1,545) from the genotype study, we compared the efficacy and safety between elderly and nonelderly patients with metastatic CRC ( = 934) or GC ( = 611) who received first- or second-line FOLFIRI (irinotecan, leucovorin, and 5-fluorouracil) chemotherapy.

Low-dose combinations of LBH589 and TRAIL can overcome TRAIL-resistance in colon cancer cell lines.

Background: Despite the considerable advances in the treatment of colorectal cancer, substantial changes in treatment strategies are required to overcome the problems of drug resistance and toxicity.

Materials And Methods: Combinations of Pan-deacetylase inhibitor LBH589 and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) were studied in three colon cancer cell lines, HCT116, colo205, and HT29 (HCT116 and colo205 are TRAIL sensitive, whereas HT29 is TRAIL resistant).

Results: It was found that TRAIL-induced cytotoxicity was enhanced by LBH589 cotreatment in the TRAIL-sensitive cell lines, and in the TRAIL-resistant HT29 cell line.

Solitary extramedullary plasmacytoma of the liver without systemic monoclonal gammopathy.

Extramedullary plasmacytoma of the liver is a very rare tumor. Although a few cases of extramedullary plasmacytoma of the liver have been reported, we could not find any report on truly localized extramedullary plasmacytoma of the liver in the literature. The patient was a 63-yr-old man who exhibited a solitary liver mass on dynamic computed tomography and magnetic resonance imaging.

Co-transplantation of human mesenchymal stem cells promotes human CD34+ cells engraftment in a dose-dependent fashion in NOD/SCID mice.

Mesenchymal stem cells (MSCs) have recently been identified and characterized in humans. Moreover, MSC secrete cytokines that can support hematopoietic progenitor growth. In the present study, we evaluated whether the efficacy of hematopoietic stem cell transplantation is improved by their co-transplantation with MSC, and whether this is positively correlated with the dose of infused MSCs.

Successful eradication of relapsed primary effusion lymphoma with high-dose chemotherapy and autologous stem cell transplantation in a patient seronegative for human immunodeficiency virus.

Primary effusion lymphoma (PEL) is a recently recognized disease that occurs most often in immunosuppressed patients, either with human immunodeficiency virus (HIV) or in the posttransplantation setting, and it occasionally occurs in nonimmunosuppressed patients. Patients present with lymphomatous effusions in serous cavities--pleura, pericardium, or peritoneum--without any identifiable tumor mass. PEL rarely responds to systemic chemotherapy, and the prognosis is poor, with a median survival time of less than 6 months for most cohorts.

A phase II study of irinotecan, 5-fluorouracil and leucovorin for treatment in patients with previously untreated advanced colorectal cancer.

Purpose: We prospectively conducted a non-randomized phase II trial to evaluate the efficacy and safety of combination irinotecan, leucovorin (LV) and 5-fluorouracil (FU) as a first-line regimen for treating patients with previously untreated advanced colorectal cancer (CRC).

Materials And Methods: Twenty-six previously untreated patients with advanced, recurrent or metastatic CRC were enrolled in this study. The patients received either irinotecan 180 mg/m(2) on day 1 with LV bolus of 200 mg/m(2) and FU bolus of 400 mg/m(2), and this was followed by FU continuous infusion of 600 mg/m(2) on day 1 and day 2 (the FOLFIRI regimen), or they were treated with LV bolus of 400 mg/m(2) and FU bolus of 400 mg/m(2) followed by FU continuous infusion of 2,400 mg/m(2) for 46 hours (the simplified FOLFIRI regimen), and these treatments were repeated every 2 weeks until disease progression.

Combination of gemcitabine and cisplatin as first-line therapy in advanced non-small-cell lung cancer.

Purpose: The prognosis of patients with advanced non-small-cell lung cancer (NSCLC) is extremely poor. Many prospective randomized trials on patients with advanced NSCLC suggested systemic chemotherapy improves both the survival and quality of life. A phase II trial was conducted to evaluate the efficacy and safety profile of the combination chemotherapy of gemcitabine and cisplatin in advanced NSCLC.

High Dose Chemotherapy and Autologous Peripheral Blood Stem Cell Transplantation for Persistent/Relapsed Ovarian Cancer.

Purpose: High dose chemotherapy (HDC) is increasingly being used for ovarian cancer. Although early studies of autotransplantation for advanced ovarian cancer have been encouraging, most reported series were small, and no randomized trials have been reported. HDC and autologous hematopoietic stem cell transplantation were rarely performed in patients with ovarian cancer in Korea, and no results have been reported with the exception of one case report.

Metastasis to the Thigh Skeletal Muscle from an Adenocarcinoma of the Duodenum.

Skeletal muscle is one of the most unusual metastatic sites for any malignancy. Duodenal cancer is extremely rare, and no cases of skeletal muscle metastasis from duodenal cancer have been reported. We report here in a case of metastasis to the skeletal muscle of the left thigh from duodenal cancer.
