BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) is a condition that often develops in young women and, consequently, physicians should frequently manage and monitor pregnant patients with this disorder. METHODS: We reviewed the charts of 30 women with chronic ITP delivered in 31 pregnancies from January 1995 to December 2003. RESULTS: Fifteen patients were diagnosed with ITP before pregnancy and sixteen patients were diagnosed during pregnancy. The mean platelet counts before pregnancy, du

Although eosinophilic fasciitis (EF) may precede hematologic malignancy or Hodgkin's disease, association with peripheral T-cell lymphoma (PTCL) is extremely rare. Only four cases of EF preceding or concomitant PTCL have been reported in the world literature. We experienced the first Korean case of EF complicated by the later relapse of peripheral T-cell lymphoma. A 63-year-old Korean male has been followed at our outpatient clinic periodically after treatment for stage IV PTCL. He had been in c

To investigate the role of angiogenesis in multiple myeloma (MM), bone marrow biopsy from 75 adults with newly diagnosed, untreated MM were evaluated. Microvessels were scored in at least 3 areas ( x 200 fields) of the highest microvessel density in representative sections of each bone marrow specimen using immunohistochemistry for CD34. Prognostic variables were also evaluated for the overall survival. Microvessel counts were significantly higher in patients with MM (n=69.42+/-9.67), compared w

BACKGROUND: The purpose of this study was to assess the efficacy and toxicity of biweekly irinotecan plus 5-fluorouracil (FU) and leucovorin (LV) in patients with relapsed or metastatic colorectal cancer. MATERIALS AND METHODS: Between March 2002 and May 2004, 24 patients with histologically confirmed relapsed or metastatic colorectal cancer were enrolled in this study. One chemotherapy cycle consisted of irinotecan 180 mg/m(2) on days 1 and 15; 5-FU 400 mg/m(2) bolus IV with 600 mg/m(2) by a 22

Telomerase is a ribonucleoprotein polymerase which contains an integral RNA and synthesizes TTAGGG nucleotide repeats at the ends of chromosomes in vertebrates. Accumulated evidence has indicated that telomerase is stringently repressed in normal human somatic tissues but reactivated in immortal and cancer cells, suggesting that activation of telomerase may play an important role in carcinogenesis. In order to assess the role of telomerase in the development of thyroid cancer, we measured the te

PURPOSE: In the treatment of advanced metastatic colorectal cancer, several new agents, such as irinotecan and oxaliplatin, have been developed, which have improved both disease free and overall survivals. Among these agents, 5-fluorouracil (5-FU) still remains one of the most active agents, and the selection of patients who can benefit from 5-FU-based chemotherapy is still important, as those unlikely to benefit could be spared the harmful side effects. The expression levels of thymidylate synt

PURPOSE: The purpose of this study was to assess the efficacy and safety of radiofrequency ablation (RFA) to treat hepatic metastasis in patients with colorectal carcinoma. MATERIALS AND METHODS: Between May 1999 and July 2002, a total of 45 tumors in 24 patients with colorectal cancer were treated with RFA. Thirteen patients received systemic chemotherapy after the RFA procedure. The ablation was performed percutaneously under ultrasound guidance using cool-tip or expandable electrodes and an R

In our experience, even elderly patients (>or=60 years) with aggressive NHL can be successfully treated with conventional chemotherapy and the important prognostic factors for survival are age, IPI, initial WBC, and CR on first line treatment.

Posttransplant lymphoproliferative disorder (PTLD) are among the most serious and potentially fatal complications of chronic immunosuppression in organ transplant recipient and also the most common malignancies, accounting for 21 percent of all malignancies in organ transplants versus 5 percent of malignancies in the general population. PTLD is associated with immunosuppression and Epstein Barr virus (EBV). Treatment modality of PTLD includes antiviral agent, interferon, intensive chemotherapy a

PTLD는 장기이식 환자에서 발생하는 치명적인 만성합병증으로 면역억제 감량, 항바이러스 제제, 화학요법, 인터페론 알파, 외과적 절제, 방사선 조사, B 세포에 대한 항체 등이 치료법으로 제시되고 있다. 저자들은 신이식 후 간 및 이식신에 발생한 미만성 거대 B세포 림프종을 진단하고 rituximab을 단독으로 사용하여 호전된 예를 경험하였기에 보고하는 바이다.

Primary intestinal T-cell lymphoma is a rare disease entity, which is approximately 10% to 25% of intestinal lymphomas, and most of the lymphomas occur in the small intestine. We report here a case of a 56-year-old woman who has been suffering from chronic diarrhea and weight loss for 6 months. Abdominal CT scan and small bowel series showed diffuse wall thickening of the small bowel. Gastroscopic examination showed diffuse erythematous lesions on the esophagus and small gastric ulcerations on t

PURPOSE: To evaluate the efficacy and toxicity of heptaplatin, paclitaxel, and 5-fluorouracil combination chemotherapy in patients with advanced gastric cancer. MATERIALS AND METHODS: Between July 2002 and September 2003, nineteen patients were enrolled in this study. Paclitaxel 135 mg/m(2) iv on day 1, heptaplatin 400 mg/m(2) iv on day 2 and 5-fluorouracil 800 mg/m(2) on day 2 approximately 4 were administered and the regimen was repeated every 3 weeks. RESULTS: The median age of the patients w

Oxaliplatin and oral capecitabine combination chemotherapy showed significant activity and favorable toxicity in patients with metastatic colorectal cancer. Further studies, with larger numbers of patients and long-tern follow-up will be needed.
