Abstract
Abstract
Background
Endocrine therapy (E) has a major role in treatment of hormone receptor (HR)-positive metastatic breast cancer (MBC). However, in contrast to western countries, premenopausal patients (PRE) more prevalent (50% of all breast cancer patients) and have less options of E than postmenopausal patients (POST) in Korea where the use of LHRH agonist in combination aromatase inhibitors (AIs) in PRE is restricted. Recently we have been successfully established nationwide cohort for the patients MBC (575 patients from 26 institutes). This study was designed to evaluate the role of E especially in PRE.
Methods
The patients with MBC were prospectively or retrospectively enrolled between September 2014 and May 2015. Only menopausal status-confirmed patients (296) were analyzed. Postmenopause was defined, based on NCCN guideline. Total duration of treatment was defined as the time from start day of any first treatment to end of any last treatment. Total duration of E was defined as the sum of time duration of each E. Overall survival was calculated from the start day of any treatment for MBC to any causes of death. This work is supported by National Strategic Coordinating Center for Clinical Research (H110C2020).
Results
A total of 296 patients with HR-positive MBC were analyzed [PRE, 169 (57.1%) and POST, 127 (42.9%)]. Except age (mean 44 and 60 years), baseline characteristics including in pathology, HER2 status, initial pathologic stage, de novo metastasis versus recurrence, surgery and adjuvant treatment (chemotherapy, endocrine therapy and radiotherapy) were well balanced. 92 (54.4%) of PRE and 77 (60.6%) of POST received at least one or more E through all treatment course. 41 (24.2%) of PRE and 44 (34.6%) received E as 1st-line treatment (p=0.034). Among PRE who received 1st-line of E, 30 (71.4%) and 9 (21.4%) of PRE received 2nd- and 3rd-line E. 20 (45.4%) and 10 (22.7%) of POST received 2nd- and 3rd- or more line of E. Most of PRE (54%) received tamoxifen+/-goserelin and 32% of PRE received AIs along with ovarian suppression. 71% of POST received AIs. As initial treatment, E was more frequently used in POST than in PRE (34.6% and 24.3%, p=0.053). Overall survival (OS) of all patients was 18.2 months (95% CI, 14.8-21.5). There was no difference in OS between PRE (17.8 months, 10.9-24.8) and POST (18.5 months, 95% CI, 13.2-23.9) (P=0.337). No difference of OS was observed (E, 18.1 moths, 95% CI, 13.0-23.3; chemotherapy 21.2 moths, 95% CI, 16.8-25.5), regardless of initial treatment. Total duration of treatment of PRE and POST were 15.2 and 13.6 months, respectively with no significant difference (p=0.389). PRE (8.3 moths, 95% CI,5.7-10.8) showed the trend toward longer duration of E in comparison with POST (5.5 moths, 95% CI,4.4-6.7), however the difference did not reach statistical significance (p=0.051).
Conclusion
E was more commonly used as 1st-line therapy in POST than in PRE. Although PRE had limited options of E, E was used in long duration of treatment especially in PRE. These findings suggested that E had a role in treatment for PRE with HR-positive MBC and could be used in treatment for PRE with good efficacy.

Abstract
Abstract
Background
Recently, many clinical trials (TRIAL) especially incorporated with molecular-targeted agents are being conducted in treatment for breast cancer worldwide. However, the relation of participating clinical trials with survival has not been actively studied. This study was designed to evaluate whether participation in clinical trials could improve overall survival (OS) or not in patients with metastatic breast cancer (MBC), compared with conventional treatment.
Method
Korean Cancer Study Group (KCSG) has successfully established Nationwide Cohort in KOREA to conduct diachronic analysis (KCSG BR 14-07). Clinical data for patients with MBC were collected from this Cohort. OS was defined as the time duration from first diagnosis of metastasis to any cause of death. This work is supported by National Strategic Coordinating Center for Clinical Research (H110C2020).
Results
A total of 575 patients with metastatic breast from 26 institutes in KOREA cancer MBC were consequently enrolled between September 2014 and May 2015. 156 (27.1%) of patients were enrolled to at least one or more clinical trials and 419 patients received only conventional treatment (CONV). Age, hormone status, HER2 status, initial pathologic stage, metastasis versus recurrence, adjuvant treatment, ECOG performance status (PS) (0, 1 vs 2 or more) were similar between TRIAL and CONV. 30% of trials were associated with HER2-targeted agents. As initial treatment, chemotherapy was more frequently used in TRIAL (85.9%) than in CONV (79.0%) (P=0.038). Number of regimens of chemotherapy was greater in TRIAL (2.9+/-1.8) than CONV (2.1+/-1.6) (P<0.001). Number of regimens of endocrine therapy (E) was similar between TRIAL (1.4+/-0.6) and CONV (1.5+/-0.7) (P=0.474). Overall survival of all patients was 16.2 months (95% CI, 14.1-18.1). TRIAL showed significant prolongation of survival, compared with CONV [21.1 (95% CI, 17.7-24.6) vs 15.1 months (95% CI, 13.1-17.2); P=0.005]. The differences in OS was constantly observed in HER2-positive [23.8 (16.7-30.9) vs 17.2 months (95% CI, 12.4-21.9); P=0.018] and Triple-negative [15.4 (10.5-20.3) vs 12.0 months (95% CI, 10.2-13.8); P=0.025]. In multivariate analysis, initial metastasis, hormone status, ECOG PS did not influence on OS between TRIAL and CONV (P=0.849)
Conclusion
Participating in clinical trials could be associated with prolongation of survival. This results constantly maintained in HER2-positive and triple-negative MBC. These findings suggested that clinical trials are useful for the patients with MBC, even if the patients do not complete the standard treatment.

Abstract
OBJECTIVE The relationship of visceral adiposity with adipocytokines and low-density lipoprotein (LDL) particle distribution and oxidation in Asian metabolically obese, normal-weight (MONW) individuals has not been evaluated. We aimed to investigate the association between visceral adiposity and adipocytokines and cardiovascular disease (CVD) risk factors in MONW Korean women with normal glucose tolerance. METHODS AND PROCEDURES We examined the metabolic characteristics of 135 non-obese (BMI <25 kg/m(2)) women aged 25-64 years. Twenty-five women (BMI <25 kg/m(2) and visceral fat adiposity (VFA) > or =100 cm(2)) were classified as MONW and 25 women (BMI <25 kg/m(2) and VFA <100 cm(2)), pair-matched for age, weight, height, and menopausal status, as control group. Plasma lipid profiles and adipocytokines were evaluated in these two groups. RESULTS MONW subjects had higher systolic (P < 0.05) and diastolic blood pressure (P < 0.005) and higher concentrations of triacylglycerol (TG) (P < 0.005), insulin (P < 0.01), and free fatty acid (FFA) (P < 0.05) than control subjects. There was no significant difference between two groups in LDL-cholesterol (LDL-C) concentrations; however, MONW subjects had smaller LDL particles (P < 0.01) and higher concentrations of oxidized LDL (ox-LDL) (P < 0.05) compared with controls. Moreover, MONW subjects had higher concentrations of tumor necrosis factor-alpha (TNF-alpha) (P < 0.05), interleukin-6 (IL-6) (P < 0.05) and leptin (P < 0.05), and lower plasma adiponectin concentrations (P < 0.05). Higher intake of saturated fat with lower ratio of polyunsaturated fatty acids (PUFAs) to saturated fatty acids (SFA) and lower fiber intake than normal subjects were found in MONW women. DISCUSSION We found an unfavorable inflammatory profile and a more atherogenic LDL profile in MONW female subjects even in the absence of a known CVD risk factors. Moreover, MONW consumed more saturated fat and less fiber than the control group.

Abstract
OBJECTIVE The purpose of this study was to determine whether common single nucleotide polymorphisms (SNPs) at the adiponectin (ADIPOQ) locus influence changes in circulating adiponectin and the features of insulin resistance in response to a weight loss intervention. SUBJECTS In total, 294 nondiabetic/overweight-obese Koreans participated in a clinical intervention study lasting 12 weeks involving a caloric reduction of -300kcal/day. METHODS Plasma adiponectin, blood lipids, glucose and insulin concentrations were measured at baseline and after weight loss. Insulin resistance was estimated by homeostasis model assessment insulin resistance (HOMA-IR) derived from fasting glucose and insulin concentrations. We genotyped for three SNPs, 45T>G, 276G>T and -11377C>G. RESULTS At baseline, HOMA-IR was significantly higher in GG homozygotes than in carriers of the T allele at SNP276G>T of the adiponectin gene (P<0.05). With regard to SNP45T>G and SNP -11377C>G, we did not find any genotype related differences in baseline levels of HOMA-IR and adiponectin. In the 45/276 haplotype test, homozygous for the TG haplotype had significantly lower concentrations of plasma adiponectin (P<0.05). After the 12-week weight loss intervention, the significant decreases in HOMA-IR (P<0.001) and increases in adiponectin (P<0.01) were observed in GG homozygotes at SNP276, which were not shown in carriers of the T allele. Furthermore, there was a significant difference in the decreases in HOMA-IR between the GG homozygotes and carriers of the T allele at SNP276 (P<0.05). Regarding SNP45T>G and SNP -11377C>G, there was no association between SNP45T>G and SNP -11377C>G and decreases in HOMA-IR. In the 45/276 haplotype test, there was a significant difference in changes of adiponectin levels among those with different haplotype combinations (P<0.05). CONCLUSION The SNP276G>T of the ADIPOQ gene is associated with different responses of circulating adiponectin and insulin resistance to mild weight loss in overweight-obese subjects.

Abstract
OBJECTIVE Perilipin (PLIN) is a class of protein-coating lipid droplets in adipocytes. We aimed to examine the association between common single-nucleotide polymorphisms (SNPs) at PLIN locus with circulating free fatty acid (FFA) and abdominal fat distribution in response to weight loss. METHODS Non-diabetic/overweight-obese Koreans (n=177) participated in a 12-week calorie restriction (-300kcal/day) program. Seven SNPs (6209T>C, 10076C>G, 10171A>T, 11482G>A, 13042A>G, 13048C>T and 14995A>T), abdominal fat areas (visceral/subcutaneous fat areas at 1st lumbar and 4th lumbar levels), serum lipids, glucose, insulin, FFA, oxidized low-density lipoprotein (LDL) and urinary 8-epi-prostaglandin F(2alpha) (PGF(2alpha)) were examined. RESULTS Single-nucleotide polymorphisms 10076C>G/10171A>T showed the strongest positive linkage disequilibrium (LD) (D'=0.923, R (2)=0.839, P<0.001) and SNPs11482G>A/14995A>T showed moderate positive LD (D'=0.824, R (2)=0.578, P<0.001). Calorie restriction induced 4.6% weight loss with significant abdominal fat reduction. In response to weight loss, subjects with nCA/nCA haplotypes at SNPs 10076C>G/10171A>T showed greater reduction in FFA levels than those with CA/CA haplotype (CA/CA: C/C at SNP 10076 and A/A at SNP 10171, nCA: non-CA haplotype carrier). On the other hand, subjects with nGA/nGA haplotype at SNPs 11482G>A/14995A>T had increased FFA levels with a rapid loss in abdominal fat, whereas GA/GA haplotype carriers had reduction in FFA levels. These results still remained significant after adjusting for age, gender and BMI. Prostaglandin F(2alpha) and oxidized LDL were also more reduced in GA/GA haplotype carriers than in nGA haplotype carriers. This effect remained significant after adjusting for baseline level, age, gender and BMI. Paradoxically, nGA haplotype carriers had increased levels of urinary PGF(2alpha) after weight reduction. CONCLUSION Fasting plasma FFA changes following a modest weight loss in overweight-obese subjects are influenced by the genetic variability at the PLIN locus. Furthermore, circulating FFA changes rather than body fat itself may determine changes in lipid peroxides such as urinary PGF(2alpha) and oxidized LDL.

Abstract
Self-assembly of one-dimensional surface structures is examined by tracking single Ir and Pd atoms on W(110) as they incorporate into chains of Ir and Pd, respectively. Ir adatoms move parallel to the chains, but do not come close to the chain sides; incorporation occurs only at the ends. Pd adatoms also migrate parallel to Pd chains, and incorporate at the ends. Occasionally, in the end region, they do jump to the side of a chain, and migrate there until they find an end site. Incorporation behavior for both Ir and Pd is driven by highly anisotropic, long-ranged interactions between atoms on the surface.

Abstract
As otitis media with effusion is common in children, the effects of a ventilation tube should be taken into account in the prescription of hearing aids for children. In ears with a ventilation tube, the external auditory canal communicates directly with the middle ear space, and so the impedance of the middle ear may change. Consequently, this will affect external-ear resonance. The aim of this study is to observe the effects of the tympanic membrane perforations caused by the ventilation tube on external-ear resonance. We selected 30 ears with otitis media with effusion to measure external-ear resonance before and after ventilation tube insertion. We compared the external-ear resonance of a control group with that of the otitis media with the effusion group and two types of ventilation-tube groups, respectively. In the subjects who have otitis media with effusion, the average gain of the peak resonance was larger than that in the control group. After ventilation-tube insertion, the amplitude of the gain decreased to the same level as the control group, but a characteristic negative gain appeared around 1000 Hz in about half of all cases. This negative gain was observed more frequently in the ventilation tube with a larger diameter. The raised peak resonance gain in the otitis media with effusion group decreased to a level roughly the same as that of the control group after ventilation-tube insertion. Provision of an additional gain in the low frequencies around 1000 Hz should be considered for patients with a ventilation tube when prescribing hearing aids.

Abstract
Juvenile polyps (JP) are the most common colonic tumor in children. Although considered benign, malignant transformation has been reported in JP. Ornithine decarboxylase (ODC) and tyrosine kinase (TyK) enzymes are markers for a rapid cell proliferation index. DNA aneuploidy score and p53 gene expression are late malignant changes seen in patients with colon cancer. In this study, we investigated ODC and TyK activities as well as DNA aneuploidy score and p53 expression in juvenile polyps compared with the adjacent normal colonic mucosa. Results showed that ODC was significantly increased in JP compared with the adjacent normal colonic mucosa. TyK activity was increased in 3/5 polyps and decreased in 2/5 polyps compared with the mucosa. Mean TyK activity was higher in JP compared with normal mucosa but did not reach significance (707 and 632 pmol/mg pmol, respectively). Moreover, changes in phosphorylization of TyK proteins was also observed in JP but not in normal mucosa. JP had a normal DNA aneuploidy score and showed no expression of p53 gene. We conclude that JP do not express p53 gene and aneuploidy but had higher activity of ODC and TyK enzymes, suggesting a higher stage of cell proliferation.

Abstract
We present the morphologic and clinical features of large bowel carcinoma in 22 patients seen over 18 years at St. Jude Children's Research Hospital. We saw 18 cases of mucinous adenocarcinoma, three of well differentiated adenocarcinoma, and one case of poorly differentiated adenocarcinoma. The patients ranged in age from 9 to 19 years with a median age of 15. There were 12 female and ten male patients; 12 were black and ten were white. Eighteen patients had Dukes' stage C disease, with median survival of seven months and one patient alive 12 months after diagnosis. Three patients had Dukes's stage B disease, with two patients surviving 16 months each and one presently alive seven months after diagnosis. Only one patient had Dukes' stage A disease and is alive 121 months after diagnosis. Large bowel carcinoma in children is predominantly mucinous adenocarcinoma and occurs in the adolescent age group. Tumor distribution is fairly even throughout the large bowel, and all subtypes of the tumor are positive for carcinoembryonic antigen (CEA) on immunohistologic study. Active tumor and tumor regrowth are always accompanied by high serum levels of CEA. The tumor has no predilection for sex, but is significantly more frequent in blacks (P less than .05). Discovery of the tumor in an early stage improves the prognosis.

Abstract
Both morphologic and clinical features of 72 consecutive cases of brain tumors, collected over 9 years at Le Bonheur Children's Medical Center, were reviewed. We identified 11 cases as glioblastoma, representing 16% of all intracranial neoplasm and 26% of glial tumors. The patients ranged in age from 1 to 15 years with the median age of 10 years. There were 4 females and 7 males; 2 blacks and 9 whites. The median survival was 9 months. The tumor was observed in both cerebrum and cerebellum. Sexual predominance was not appreciable, although there was male excess. The tumor was significantly more frequent in whites than blacks (p less than 0.05). Similar racial predominance was noted in the other, more common brain tumors in children such as astrocytoma and medulloblastoma.

Abstract
A 19-month-old girl had a congenital aneurysm of the neck vein. We attribute the pathogenesis of venous aneurysm to a defective vascular wall. The treatment of choice is simple surgical excision.

Abstract
Forty-one cases of childhood "histiocytic" lymphoma were studied morphologically and immunologically to determine whether this tumor type is composed of true histiocytic cells. Lysozyme and alpha-1-antichymotrypsin were used as markers for histiocytes, and cytoplasmic immunoglobulins were used as markers for B cells. Both indirect immunofluorescence and immunoperoxidase methods were used for functional characterization of tumor cells. Eight different subgroups were identified in the series, and only one case was proved to be true histiocytic lymphoma. When survival was evaluated for different subgroups, excluding convoluted lymphocytic, unclassified, and true histiocytic lymphomas, mixed follicular cell lymphoma had the most favorable prognosis; six of seven patients survived for at least one year. Immunoblastic lymphoma, by contrast, had an unfavorable prognosis; none of four patients were alive one year after diagnosis. The difference is statistically significant (P < 0.05) by chi-square analysis. Other groups of lymphoma (large cleaved, large noncleaved, and small noncleaved) had an intermediae prognosis (three of five, six of nine, and five of nine patients surviving at one year). Our results indicate that "histiocytic" lymphoma is a morphologically heterogeneous group of neoplasms, mostly not related to true histiocytes, and that morphologic subclassification may be useful in predicting prognosis.

Abstract
Antisera against myosin of human normal skeletal muscle and against rhabdomyoblasts of autopsy-proved rhabdomyosarcoma were raised in white rabbits, purified, and assessed for their usefulness in the diagnosis of childhood rhabdomyosarcoma. The specificity of the antisera was tested by both immunofluorescence and immunoperoxidase methods in seven cases of autopsy-proved rhabdomyosarcoma, five of malignant lymphoma, three of neuroblastoma, and two of Ewing's sarcoma. Antimyosin serum tested positive for all cases of rhabdomyosarcoma and negative for other types of tumor. Antirhabdomyoblast serum was positive in all cases of rhabdomyosarcoma and cross-reacted with cases of neuroblastoma and Ewing's tumor, although the intensity of staining was much decreased. Our results indicate that antimyosin serum is specific for childhood rhabdomyosarcoma and can be used to differentiate this from other childhood "round cell" tumors.
