BACKGROUND: Gastric cancer with bone marrow metastases is known to pursue a rapidly deteriorating clinical course. We conducted a retrospective analysis to evaluate clinical manifestations and prognosis of gastric cancer patients with bone marrow metastases. METHODS: Between September 1994 and February 2006, 39 gastric cancer patients with pathologically confirmed bone marrow dissemination were selected. RESULTS: The majority of the patients showed younger age, poorly differentiated adenocarcino

The increased cumulative duration of metformin use decreased the recurrence, all-cause mortality, and cancer-specific mortality rates among GC patients with diabetes who underwent gastrectomy.

We investigated the value of Epstein-Barr virus (EBV) DNA load in unfractionated whole blood for the diagnosis and prognosis of EBV-associated lymphoma. From July 2004 to July 2007, we compared EBV DNA loads in 101 patients with lymphoma and 105 control individuals. The median copy number of EBV was higher in patients with EBV-positive lymphoma (p<0.001). In patients with natural killer (NK)/T-cell lymphomas, the median EBV DNA load at presentation was significantly related to the stage (p = 0.0

BACKGROUND: We performed multicenter study to define clinical characteristics of noncutaneous melanomas and to establish prognostic factors patients who received curative resection. METHODS: Of the 141 patients who were diagnosed of non-cutaneous melanoma at 4 institutions in Korea between June 1992 and May 2005, 129 (91.5%) satisfied the selection criteria. RESULTS: Of the 129 noncutaneous melanoma patients, 14 patients had ocular melanoma and 115 patients had mucosal melanoma. For mucosal mela

BACKGROUND: Many factors influence bone metastases of lung cancer, and several studies report about survival of skeletal metastasis. However, few studies have focused on identifying the prognostic factors for skeletal metastasis of lung cancer, especially following orthopedic surgery. We conducted a retrospective analysis of the clinical characteristics of skeletal metastasis from lung cancer and discuss the prognostic factors. METHODS: We performed a medical record review of 202 patients who we

Gastric cancer (GC) is a leading cause of death. We aim to establish a clinically relevant assay that encompasses recent molecular classifications and provides useful clinical information in a large cohort of GC patients. A consecutive series of 438 GC patients that underwent palliative chemotherapy between 2014 and 2015 were assessed using 10 GC panels: EBER in-situ hybridization, immunohistochemistry for mismatch repair (MMR) proteins (MLH1, PMS2, MSH2, and MSH6), receptor tyrosine kinases (RT

OBJECTIVE: We aimed to describe the efficacy and safety of sunitinib in unselected Korean advanced renal cell carcinoma (RCC) patients. PATIENTS AND METHODS: From November 2005 to August 2008, 132 histologically confirmed advanced RCC patients (100 in the global expanded access program) were enrolled. Response and toxicity were assessed regularly according to the protocol. RESULTS: Within this population, 82.6% had clear cell RCC, and 28.8% were treatment naïve. Patients received a median of 5 c

The histologic subtype, and margin status were independently associated with OS, and adjuvant radiotherapy seems to confer survival benefit in low grade tumors. Our prognostic model for primary liposarcoma demonstrated distinct three groups of patients with good prognostic discrimination.

Remifentanil is a commonly used opioid in anesthesia with cardioprotective effect in ischemia-reperfused (I/R) heart. We evaluated the influence of remifentanil on myocardial infarct size and expressions of proteins involved in apoptosis in I/R rat heart following various time protocols of remifentanil administration. Artificially ventilated anesthetized Sprague-Dawley rats were subjected to a 30 min of left anterior descending coronary artery occlusion followed by 2 h of reperfusion. Rats were

To investigate the frequency and the prognostic impact of fibroblast growth factor receptor 1 (FGFR1) gene amplification in 526 curatively resected esophageal squamous cell carcinoma (ESCC). Using fluorescent in situ hybridization, high amplification was defined by an FGFR1/centromer 8 ratio is ≥ 2.0, or average number of FGFR1 signals/tumor cell nucleus ≥ 6.0, or percentage of tumor cells containing ≥ 15 FGFR1 signals or large cluster in ≥ 10%. Low amplification was defined by ≥ 5 FGFR1 signals

OBJECTIVE: Well-differentiated papillary mesothelioma is an uncommon subtype of mesothelioma with a frequently indolent course, although it occasionally manifests in a more aggressive form. To establish a treatment strategy for this rare disease, we report the clinical characteristics and outcomes of 15 patients with well-differentiated papillary mesothelioma. METHODS: All pathologically diagnosed well-differentiated papillary mesothelioma cases were reviewed between 1998 and 2012. RESULTS: Of t

A case of catecholamine cardiomyopathy associated with paraganglioma, which was rescued by percutaneous cardiopulmonary support system (PCPS), is presented. Unlike typical apical ballooning, transthoracic echocardiography and left ventriculography revealed severe left ventricular (LV) dysfunction and an abnormal contractile pattern, consisting of akinesis of the basal and midventricular segments and hyperkinesis of the apical segments. Because of the intractable cardiogenic shock, despite conven

Abstract We aimed to determine the activity of the anti-VEGF receptor tyrosine-kinase inhibitor, pazopanib, combined with the anti-PD-L1 inhibitor, durvalumab, in metastatic and/or recurrent soft tissue sarcoma (STS). In this single-arm phase 2 trial (NCT03798106), treatment consisted of pazopanib 800 mg orally once a day and durvalumab 1500 mg once every 3 weeks. Primary outcome was overall response rate (ORR) and secondary outcomes included progression-free survival (PFS), overall survival, di
