RESUMO

Background/Aims@#Patients with pancreatic cancer (PC) generally have poor clinical outcomes. Early determination of their prognosis is crucial for developing a therapeutic strategy. Recently, various inflammatory markers have been validated as prognostic indicators for many cancers, including PC. However, few studies have evaluated these markers together. Thus, the purpose of this study was to comprehensively evaluate the value of inflammatory markers as prognostic indicators in patients with advanced PC treated with gemcitabine-based chemotherapy as the first line regimen. @*Methods@#This was a single-center retrospective study evaluating 302 patients with advanced PC who began first line treatment between November 2004 and August 2016. These patients were monitored until June 2017. Survival rates were assessed with univariate and multivariate analyses. Continuous variables were separated using the normal range or ideal cut-off levels determined by receiver operating curve analyses. @*Results@#Among inflammatory markers evaluated, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and C-reactive protein (CRP) to albumin ratio (CRP-albumin ratio) were independent predictors of overall survival (hazard ratio, 1.712, 1.345, and 1.454, respectively). Difference in survival rates was significant (p < 0.001) among three groups divided by the number of marker-related risks. @*Conclusions@#Baseline inflammatory markers including NLR, PLR, and CRP-albumin ratio are useful in predicting survival rates in patients with PC. Combining these three markers is proven to be valuable.

RESUMO

Granular cell tumor is rare tumor origination from Schwann cell. It occurs extremely rarely in pediatric age. Treatment is complete resection, but this may not always be possible because of the risk of airway stenosis or vocal cord paralysis. Six year-old male patient visited otolaryngology clinic due to dyspnea and stridor. Posterior glottis mass was indentified and was partially resected to confirm histology and resolve airway obstruction. One year after operation, the patient was living well without re-growing of tumor. We report a case of granular cell tumor in pediatric larynx with a review of literature.

RESUMO

PURPOSE: The purpose of this study is to suggest a treatment strategy for stage IV gastric cancer by investigating the behavioral difference between initially and recurrent metastatic disease. METHODS: We reviewed the medical records of the patients who underwent chemotherapy alone for metastatic gastric cancer between January 2006 and September 2013. Patients were divided into those who underwent chemotherapy for metastatic disease since initial diagnosis (IM group) and for metastatic recurrence after curative surgery (RM group). Survival and causes of death were compared between the 2 groups, and significant prognostic factors were also investigated. RESULTS: A total of 170 patients were enrolled in this study. Of these patients, 104 were included in the IM group and 66 in the RM group. Overall survival of the IM group did not differ from that of RM (P = 0.569). In the comparison of the causes of death, the IM group had a greater tendency to die from bleeding (P = 0.054) and pneumonia (P = 0.055). In multivariate analysis, bone metastasis (P < 0.001; HR = 2.847), carcinoma peritonei (P = 0.047; HR = 1.766), and the frequency of chemotherapy (P < 0.001; HR = 0.777) were significantly associated with overall survival of IM group. CONCLUSION: Disease-burden mainly contributes to the prognosis of metastatic gastric cancer, although noncurative gastrectomy may be helpful in reducing the mortality of initially metastatic disease. Therefore, disease-burden should be also prioritized in determining the treatment strategies for stage IV gastric cancer.

RESUMO

Phelan-McDermid syndrome is a rare genetic disorder caused by the terminal or interstitial deletion of the chromosome 22q13.3. Patients with this syndrome usually have global developmental delay, hypotonia, and speech delays. Several putative genes such as the SHANK3, RAB, RABL2B, and IB2 are responsible for the neurological features. This study describes the clinical features and outcomes of Korean patients with Phelan-McDermid syndrome. Two patients showing global developmental delay, hypotonia, and speech delay were diagnosed with Phelan-McDermid syndrome via chromosome analysis, fluorescent in situ hybridization, and multiplex ligation-dependent probe amplification analysis. Brain magnetic resonance imaging of Patients 1 and 2 showed delayed myelination and severe communicating hydrocephalus, respectively. Electroencephalography in patient 2 showed high amplitude spike discharges from the left frontotemporoparietal area, but neither patient developed seizures. Kidney ultrasonography of both the patients revealed multicystic kidney disease and pelviectasis, respectively. Patient 2 experienced recurrent respiratory infections, and chest computed tomography findings demonstrated laryngotracheomalacia and bronchial narrowing. He subsequently died because of heart failure after a ventriculoperitoneal shunt operation at 5 months of age. Patient 1, who is currently 20 months old, has been undergoing rehabilitation therapy. However, global developmental delay was noted, as determines using the Korean Infant and Child Development test, the Denver developmental test, and the Bayley developmental test. This report describes the clinical features, outcomes, and molecular genetic characteristics of two Korean patients with Phelan-McDermid syndrome.

RESUMO

PURPOSE: Metabolic liver disease (MLD) often progresses to life-threatening conditions. This study intends to describe the outcomes of liver transplantation (LTx) for MLD at a living donor-dominant transplantation center where potentially heterozygous carrier grafts are employed. METHODS: We retrospectively evaluated the medical records of 54 patients with MLD who underwent LTx between November 1995 and February 2012 at Asan Medical Center in Seoul, Korea. The cumulative graft and patient survival rates were analyzed according to patient age, and living or deceased donor LTx. Recurrence of the original disease was also investigated. RESULTS: The post-transplant cumulative patient survival rates at one, five, and 10 years were 90.7%, 87.5% and 87.5%, and the graft survival rates were 88.8%, 85.5%, and 85.5%, respectively. There were no differences in the patient survival rates according to the recipient age, human leukocyte antigen matching, and living or deceased donor LTx. There were also no differences in the patient survival rates between the MLD and the non-MLD groups for children. Recurrence of the original metabolic disease was not observed in any patient during the follow-up period. CONCLUSION: Our results suggest that the living donor-dominant transplantation program is well-tolerated in MLD without recurrence of the original MLD using all types of transplantation.

RESUMO

BACKGROUND: The relationship between economics and health has been of great interest throughout the years. The accumulated data is not sufficient enough to carry out long-term studies from the viewpoint of morbidity, although Korea National Health and Nutrition Examination Survey (KNHANES) was carried out yearly since 1998 in Korea. Thus, we investigated the effect of the 2008 global economic crisis on health indicators of Korea. METHODS: Health indicators were selected by paired t-test based on 2007 and 2009 KNHANES data. Age, gender, body mass index (BMI), smoking, drinking, exercise, education, income, working status, and stress were used as confounding factors, which were analyzed with logistic and probit analyses. Validation was done by comparing gross domestic product (GDP) growth rates and probit analyses results of 2007-2012 KNHANES data. RESULTS: Among several health indicators, the prevalence of hypertension and stress perception was higher after the economic crisis. Factors related with higher hypertension prevalence include older age, male gender, higher BMI, no current tobacco use, recent drinking, lower education levels, and stress perception. Factors related with more stress perception were younger age, female gender, current smoking, lower education levels, and lower income. GDP growth rates, a macroeconomic indicator, are inversely associated with hypertension prevalence with a one-year lag, and also inversely associated with stress perception without time lag. CONCLUSION: The economic crisis increased the prevalence of hypertension and stress perception. In the case of GDP growth rate change, hypertension was an inversely lagging indicator and stress perception was an inversely-related coincident indicator.

RESUMO

BACKGROUND: Small vessel disease is an important cause of cerebrovascular diseases and cognitive impairment in the elderly. There have been conflicting results regarding the relationship between Helicobacter pylori infection and ischemic stroke. This study aimed to examine the association between H. pylori infection and cerebral small vessel disease. METHODS: The study included 1,117 patients who underwent brain magnetic resonance imaging and H. pylori identification between 2005 and 2013 at Health Promotion Center, Seoul National University Hospital. Multivariable logistic regression analysis was used to assess the association between H. pylori infection and small vessel disease with adjustment for age, sex, hypertension, diabetes mellitus, dyslipidemia, body mass index, smoking status, problem drinking, and antiplatelet use. RESULTS: The adjusted odds ratios (aORs) for the association between H. pylori infection and silent brain infarction and cerebral microbleeds were 1.03 (95% confidence interval [CI], 0.66-1.61) and 0.70 (95% CI, 0.38-1.28), respectively. The aORs for silent brain infarction and cerebral microbleeds were 0.81 (95% CI, 0.44-1.44) and 0.59 (95% CI, 0.30-1.18) in patients aged 65 years, respectively. Moreover, the aORs for silent brain infarction and cerebral microbleeds were 0.96 (95% CI, 0.54-1.71) and 0.74 (95% CI, 0.33-1.69) in H. pylori-infected patients without atrophic gastritis and 0.89 (95% CI, 0.48-1.62) and 0.99 (95% CI, 0.43-2.27) in those with atrophic gastritis, respectively. CONCLUSION: No association between H. pylori infection and small vessel disease was observed. H. pylori-induced inflammation may not be a risk factor for microcirculatory damage in the brain.

RESUMO

Standard endocrine therapy and chemotherapy can induce long-term remission in breast cancer patients; however, breast cancer can recur at any site. Pulmonary nodules with lymphadenopathy in advanced cancer patients are likely to be assumed as metastases. A 44-year-old woman with a history of breast cancer was presented to our institution with abnormal findings on 18-fluorodeoxyglucose positron emission tomography imaging, which suggested lung metastasis. She had previously been diagnosed with breast cancer (T1N2M0, Stage IIIa, intraductal carcinoma, triple negative cancer). Histological analysis of the mediastinal lymph node biopsy demonstrated sarcoidosis, showing a chronic, non-caseating, granulomatous inflammation. Our case highlights the need for non-malignant diagnoses in those with prior malignancies, and the need for histological evaluations in the event of first recurrence following potentially curative therapy.

RESUMO

Paragangliomas are rare tumors that arise from the extra-adrenal chromaffin cells, and malignancy is defined by the presence of metastases to sites that normally lack chromaffin tissue. The main therapeutic targets are tumor reduction and control of excessive catecholamine secretion. Currently, the adjuvant therapy to surgery is radiotherapy treatment using high-dose MIBG; chemotherapy is currently evolving. We report herein a case of malignant paraganglioma with lung and spine metastasis that occurred 16 years after primary tumor excision and was treated with high dose MIBG radiotherapy and chemotherapy.

RESUMO

PURPOSE: There is no established standard second-line chemotherapy for patients with advanced or metastatic urothelial carcinoma (UC) who failed gemcitabine and cisplatin (GC) chemotherapy. This study was conducted in order to investigate the efficacy and toxicity of modified methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) in patients with metastatic UC previously treated with GC. MATERIALS AND METHODS: We retrospectively analyzed 28 patients who received modified MVAC between November 2004 and November 2012. All patients failed prior, first-line GC chemotherapy. RESULTS: The median age of patients was 64.0 years (range, 33.0 to 77.0 years), and 23 (82.1%) patients had an Eastern Cooperative Oncology Group performance status of 0 or 1. The overall response rate and the disease control rate were 36.0% and 64.0%, respectively. After a median follow-up period of 38 weeks (range, 5 to 182 weeks), median progression free survival was 21.0 weeks (95% confidence interval [CI], 6.3 to 35.7 weeks) and median overall survival was 49.0 weeks (95% CI, 18.8 to 79.3 weeks). Grade 3 or 4 hematological toxicities included neutropenia (n=21, 75.0%) and anemia (n=9, 32.1%). Grade 3 or 4 non-hematological toxicities did not occur and there was no treatment-related death. CONCLUSION: Modified MVAC appears to be a safe and active chemotherapy regimen in patients with stable physical status and adequate renal function after GC treatment.

RESUMO

Smith-Lemli-Opitz syndrome (SLOS) is a rare autosomal recessive disorder caused by 7-dehydrocholesterol reductase deficiency. The characteristic clinical features are syndactyly of the second and third toes, facial dysmorphism, multiple malformations, and intellectual disability. Few cases of SLOS have been reported in Korea. We observed a male patient with SLOS who presented with typical facial features, undescended testes, microcephaly, bilateral syndactyly of the second and third toes, and cardiac defects, including patent ductus arteriosus and atrial septal defect. Mutation analysis of the DHCR7 gene identified compound heterozygous mutations of c.907G>A (p.Gly303Arg) and c.1055G>A (p.Arg352Gln). In a review of the literature, c.1054C>T (p.Arg352Trp) was the most common mutation reported in Far East Asian countries. This report describes the clinical features, biochemical data, molecular characteristics, and clinical outcome of a Korean patient with SLOS.

RESUMO

OBJECTIVE: The purpose of this study was to determine the incidence and risk factors of infections associated with implantable venous access ports (IVAPs). MATERIALS AND METHODS: From August 2003 through November 2011, 1747 IVAPs were placed in our interventional radiology suite. One hundred forty four IVAPs were inserted in patients with hematologic malignancy and 1603 IVAPs in patients with solid tumors. Among them, 40 ports (23 women and 17 men; mean age, 57.1 years; range, 13-83) were removed to treat port-related infections. We evaluated the incidence of port-related infection, patient characteristics, bacteriologic data, and patient progress. Univariable analyses (t test, chi-square test, and Fisher's exact test) and multiple logistic regression analyses were used to determine the risk factors for IVAP related infection. RESULTS: Overall, 40 (2.3%) of 1747 ports were removed for symptoms of infection with an incidence rate of 0.067 events/1000 catheter-days. According to the univariable study, the incidences of infection were seemingly higher in the patients who received the procedure during inpatient treatment (p = 0.016), the patients with hematologic malignancy (p = 0.041), and the patients receiving palliative chemotherapy (p = 0.022). From the multiple binary logistic regression, the adjusted odds ratios of infection in patients with hematologic malignancies and those receiving palliative chemotherapy were 7.769 (p = 0.001) and 4.863 (p = 0.003), respectively. Microorganisms were isolated from 26 (65%) blood samples, and two of the most causative organisms were found to be Staphylococcus (n = 10) and Candida species (n = 7). CONCLUSION: The underlying hematologic malignancy and the state of receiving palliative chemotherapy were the independent risk factors of IVAP-related infection.

RESUMO

PURPOSE: Activating mutation of the KRAS oncogene is an established negative predictor for anti-epidermal growth factor receptor (anti-EGFR) therapies in metastatic colorectal cancer (CRC). However, KRAS mutation as a prognostic factor of survival outcome remains controversial in CRC, independent of anti-EGFR therapies. MATERIALS AND METHODS: We conducted a retrospective analysis of 103 CRC patients who were available for evaluation of KRAS mutation status. None of the patients analyzed had received anti-EGFR therapies. The role of KRAS mutation status was evaluated as a predictive factor for oxaliplatin or irinotecan and as a prognostic factor in CRC patients who did not receive anti-EGFR therapies. RESULTS: Mutations in KRAS were observed in 48.5% of patients. The response for oxaliplatin- (p=0.664) and irinotecan-based (p=0.255) cytotoxic chemotherapy did not differ according to the KRAS mutation status. In addition, no significant difference in progression free survival (PFS; oxaliplatin, p=0.583 and irinotecan, p=0.426) and overall survival (OS; p=0.258) was observed between the wild and mutant type of the KRAS gene. In univariate and multivariate analyses, KRAS mutations did not have a major prognostic value regarding PFS (oxaliplatin: hazard ratio, 0.892; 95% confidence interval [CI], 0.590 to 1.347; p=0.586 and irinotecan: hazard ratio, 0.831; 95% CI, 0.524 to 1.319; p=0.433) or OS (hazard ratio, 0.754; 95% CI, 0.460 to 1.236; p=0.263). In addition, anti-vascular endothelial growth factor therapies did not affect PFS to oxaliplatin or irinotecan and OS. CONCLUSION: KRAS mutation is not a prognostic marker for PFS to oxaliplatin or irinotecan and OS in CRC patients who did not receive anti-EGFR therapies.

RESUMO

PURPOSE: As the number of elderly patients diagnosed with non-small cell lung carcinoma (NSCLC) increases, the number of these patients receiving chemotherapy also increases. However, limited data exists regarding the use of chemotherapy in advanced NSCLC patients who are 75 years of age or older. MATERIALS AND METHODS: Between May 2002 and October 2008, data for 48 advanced NSCLC patients who were 75 years of age or older who had been treated with chemotherapy were retrospectively analyzed. RESULTS: The median age of study participants at the time of first line chemotherapy was 76 years (range, 75 to 87 years) and their median Charlson comorbidity index was 2 (range, 1 to 4). Of the total 48 patients, 43 patients (90%) were treated by platinum-based doublet as a first line chemotherapy regimen. Median progression free survival for first line chemotherapy was 5.7 months (95% confidence interval [CI], 4.93 to 6.47 months) with an overall response rate of 33.3%. After first line chemotherapy, only 14 of the 48 patients (29.2%) received second line chemotherapy. The median overall survival (OS) for these patients was 8.2 months (95% CI, 4.44 to 11.96 months). Multivariate analysis results indicated that female gender and having received second-line or more chemotherapy were independent prognostic factors for increased OS for all 48 patients. Charlson Index was not a significant independent prognostic factor for survival. There were 9 treatment related deaths due to infectious causes (18.8%). CONCLUSION: Patients 75 years of age or older with advanced NSCLC may obtain clinical benefit from the administration of platinum-based doublet or single agent chemotherapy. However, oncologists must consider the aspect of safety in relation to the clinical benefits when managing this patient group.

RESUMO

The aim of this project was to use 3D scanning data collected at incident scenes and various evidence to 1) develop surveying methods based on 3D data consisting of overall and detailed scene evidence, captured by long-range and micros-canner, which can be shared by personnel working in different fields such as forensic medicine, video analysis, physical analysis, traffic engineering, and fire investigation; 2) create digital storage for human skeletons and set the foundation for virtual anthropology; and 3) improve the credibility of 3D evidence by virtual remodeling and simulation of incident scenes and evidence to provide a basis for advanced and high-tech scientific investigation. Two complete skeletons of male and female were scanned using 3D micro-scanner. Each bone was successfully reproduced and assembled in virtual space. In addition, recreating evidence scheduled for invasive examination by creating RP (rapid prototype) was possible. These outcomes could play an important role in setting up the new field of virtual anthropology. Case-specific surveying methods were developed through analysis of 3D scanning data collected by long-range surface scanners at the scenes of vehicular accidents, falls, shootings, and violent crimes. A technique and recording method was also developed for detecting forged seals by micro-scanning the pressure exerted on the seal. Appraisal methods developed in this project could be utilized to secure 3D data of human skeletal remains and incident scenes, create a standard for application, and increase objectivity, reproducibility, and accuracy of scanning methods. We plan to develop case-specific 3D data analysis techniques to improve the credibility of analysis at the NFS and to establish a 3D data collection and analysis team.

RESUMO

BACKGROUND: Iron is essential for cell proliferation and viability. It has been reported that iron depletion by a chelator inhibits proliferation of some cancer cells. Deferasirox is a new oral iron chelator, and a few reports have described its effects on lymphoma cells. The goal of this study was to determine the anticancer effects of deferasirox in malignant lymphoma cell lines. METHODS: Three human malignant lymphoma cell lines (NCI H28:N78, Ramos, and Jiyoye) were treated with deferasirox at final concentrations of 20, 50, or 100 microM. Cell proliferation was evaluated by an MTT assay, and cell cycle and apoptosis were analyzed by flow cytometry. Western blot analysis was performed to determine the relative activity of various apoptotic pathways. The role of caspase in deferasirox-induced apoptosis was investigated using a luminescent assay. RESULTS: The MTT assay showed that deferasirox had dose-dependent cytotoxic effects on all 3 cell lines. Cell cycle analysis showed that the sub-G1 portion increased in all 3 cell lines as the concentration of deferasirox increased. Early apoptosis was also confirmed in the treated cells by Annexin V and PI staining. Western blotting showed an increase in the cleavage of PARP, caspase 3/7, and caspase 9 in deferasirox-treated groups. CONCLUSION: We demonstrated that deferasirox, a new oral iron-chelating agent, induced early apoptosis in human malignant lymphoma cells, and this apoptotic effect is dependent on the caspase-3/caspase-9 pathway.

RESUMO

PURPOSE: The purpose of this study was to determine the efficacy and safety of treatment using gemcitabine and capecitabine for patients with advanced pancreatic cancer. MATERIALS AND METHODS: Patients with advanced unresectable pancreatic adenocarcinoma were enrolled in the study. Inclusion criteria included no prior systemic chemotherapy or radiation therapy, at least one radiographically documented and measurable tumor lesion, and adequate patient organ functions. The patients received 1,000 mg/m2 gemcitabine intravenously on days 1, 8 and 15, and 830 mg/m2 of oral capecitabine twice a day on days 1-21 of a 28-day cycle. RESULTS: Fifty patients with a median age of 53 years (range, 39 to 76 years) were enrolled in the study. The median follow-up was 10.0 months. The objective response rate of the 50 patients was 48.0% (95% CI, 22.5 to 57.1%). The median time to progression and overall survival were 6.5 months (95% CI, 2.3 to 8.7 months) and 10.0 months (95% CI, 5.7 to 16.7 months), respectively. Grade 3-4 toxicities associated with chemotherapy included neutropenia (22%), anemia (8%), thrombocytopenia (6%), and hand-foot syndrome (10%). CONCLUSION: Combination chemotherapy using gemcitabine and capecitabine was well tolerated and demonstrated promising efficacy in the treatment of advanced pancreatic cancer.

RESUMO

Advanced gastric cancer with skeletal muscle metastasis is a rare occurrence. Here, we report a rare case of gastric carcinoma with psoas muscle metastasis. This patient had advanced gastric carcinoma and complained of inability to extend the left hip joint due to pain. Because magnetic resonance imaging (MRI) revealed an iliopsoas mass showing heterogeneous signal intensity with fluid collection and enhancement around the mass, we speculated that the mass was an intramuscular metastatic tumor from primary gastric carcinoma as well as an intramuscular abscess. Histopathologically, the patient had a metastasis from primary gastric adenocarcinoma. Therefore, the patient was treated with radiotherapy and subsequent chemotherapy.
