Abstract
Overactivated NLRP3 inflammasome has been shown to associate with an increasing number of disease conditions. Activation of the NLRP3 inflammasome results in caspase-1-catalyzed formation of active pro-inflammatory cytokines (IL-1β and IL-18) resulting in pyroptosis. The multi-protein composition of the NLRP3 inflammasome and its sensitivity to several damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs) make this extensively studied inflammasome an attractive target to treat chronic conditions. However, none of the known NLRP3 inhibitors has been approved for clinical use. Sulfonylurea and covalent inhibitors with electrophilic warhead (Michael acceptor) are among the prominent classes of compounds explored for their NLRP3 inhibitory effects. Chalcone, a small molecule with α, β unsaturated carbonyl group (Michael acceptor), has also been studied as a promising scaffold for the development of NLRP3 inhibitors. Low molecular weight, easy to manipulate lipophilicity and cost-effectiveness have attracted many to use chalcone scaffold for drug development. In this review, we highlight chalcone derivatives with NLRP3 inflammasome inhibitory activities. Recent developments and potential new directions summarized here will, hopefully, serve as valuable perspectives for investigators including medicinal chemists and drug discovery researchers to utilize chalcone as a scaffold for developing novel NLRP3 inflammasome inhibitors.

Abstract
BACKGROUND High-risk human papilloma virus (HR HPV) infection is a major factor leading to the development of uterine cervical cancer. Data suggest that alterations in lipid metabolism are related to the pathogenesis of cervical cancer. Specifically, the uptake of exogenous fatty acids and their intracellular storage in lipid droplets enables cancer cells to survive and adapt to the changing tumor environment. MATERIALS AND METHODS We compared the immunohistochemical expression of fatty acid transport protein 4 (FATP4), and cluster of differentiation 36/fatty acid translocase (CD36/FAT) in normal cervical epithelium, low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and squamous cell carcinoma (SCC) tissues of the uterine cervix. We also investigated the clinicopathological implications of these fatty acid transporters in SCC. RESULTS Compared with that in normal cervical tissues, the expression of FATP4 was lower in LSIL (p=0.002), HSIL (p=0.006), and SCC (p=0.001). In contrast, CD36 expression was higher in SCC tissues than in normal cervical tissues (p<0.001). In normal cervical tissues, HR HPV-infected lesions exhibited a decrease in FATP4 (p<0.001) and an increase of CD36 (p=0.134), compared to those that were not infected with HR HPV. High CD36 expression was associated with a shorter recurrence-free survival (p<0.001). However, high FATP4 levels showed no significant correlation with the clinicopathological parameters of SCC. CONCLUSION Altered expression levels of FATP4 and CD36 are unique features that might be related to HR HPV infection and promote tumorigenesis and progression of cervical cancer.

Abstract
Abstract
Introduction/Objective
The Kidd blood group antigens are urea transporters found on the surface of red blood cells, renal tubular epithelial cells, and endothelial cells in the renal medulla and vasa recta. While controversial, some reports have described an association between Kidd antigen donor/recipient mismatches and kidney transplant rejection when recipients possess or form anti-Kidd alloantibodies. To date, none of these reports have described development of a thrombotic microangiopathy (TMA) in the renal graft associated with these antibodies. We describe a case of fulminant renal transplant rejection associated with TMA in a patient with anti-Jk(a) alloantibodies who received a deceased-donor kidney transplant (DDKT).
Methods/Case Report
A 64-year-old woman with end-stage renal disease secondary to AL amyloidosis caused by plasma cell neoplasm received a DDKT associated with delayed graft function. No pre- or post-transplant donor specific antibodies (DSA) were detected, the flow crossmatch testing was negative, and a pre-operative type and screen identified anti-Jk(a) alloantibodies. On post-transplant day 5, her creatinine remained elevated at 6 mg/dL (ref range: 0.4–1.3 mg/dL) with an acute drop in platelets and undetectable haptoglobin. Allograft biopsy showed a combination of TMA with some additional evidence of acute cellular rejection. Tacrolimus was stopped to rule out drug-induced TMA, and the workup showed negative Shiga toxin, normal ADAMTS13 activity, negative atypical HUS genetic testing, and negative antiphospholipid syndrome testing. Genotyping of the donor kidney was positive for the Jk(a) antigen. Eculizumab, IVIG, and a trial of 8 sessions of therapeutic plasma exchange (TPE) were administered. Her creatinine improved (1.93–2.05 mg/dL), indicating a significant antibody-mediated etiology to her delayed graft function. About one month later, her creatinine worsened, and she received another trial of TPE with IVIG and eculizumab. Despite a mild decrease in her creatinine, repeat biopsies showed acute cellular rejection, persistent TMA, and chronic allograft injury. No DSAs were ever detected. Her creatinine never recovered, and she is now dialysis-dependent.
Results (if a Case Study enter NA)
NA
Conclusion
We speculate that anti-Jk(a) antibodies interacting with a Jk(a)-positive donor kidney account for graft TMA. This case underscores the potential importance of matching Kidd antigens in kidney transplantation.

Abstract
Increased cell proliferation is a critical hallmark of cancer development and progression. The proliferation of tumor cells depends on mitotic deregulation. Here, we identified the differentially expressed genes (DEGs) in gastric cancer (GC) through RNA sequencing data and bioinformatics analysis. Subsequent functional and pathway enrichment analyses showed that the screened DEGs were enriched in the mitosis-associated pathway. Based on the analysis results, we selected two signatures (aurora kinase A [AURKA] and kinesin family member C1 [KIFC1]) to determine their clinicopathological significance. The results showed a significant positive correlation between AURKA and KIFC1 expression both at the mRNA and protein levels. AURKA expression was positively correlated with distant metastases (p = 0.032) and tumor-node-metastasis (TNM) stage (p = 0.001). Elevated KIFC1 expression was significantly associated with tumor size (p = 0.029), depth of invasion (p < 0.001), lymph node metastasis (p < 0.001), distant metastasis (p = 0.023), and TNM stage (p < 0.001). Higher AURKA (hazard ratio [HR] = 1.3, p < 0.001) and KIFC1 (HR = 1.41, p < 0.001) mRNA levels were also significantly correlated with poor overall survival. Thus, AURKA and KIFC1 could serve as potential prognostic markers and therapeutic targets for GC.

Abstract
As patients with non-muscle-invasive bladder cancer (NMIBC) show a high degree of heterogeneity in tumor recurrence or progression, many clinicians demand a detailed risk stratification. Although modified fatty acid metabolism in cancer cells is reported to reflect malignant phenotypes such as metastasis, the impact of fatty acid transporters on NMIBC has never been investigated. This study examined the clinicopathologic implications of fatty acid transporters such as fatty acid transport protein 4 (FATP4), cluster of differentiation 36/fatty acid translocase (CD36/FAT), and long chain acyl CoA synthetase 1 (ACSL1) in 286 NMIBC cases. This study revealed that FATP4, CD36, and ACSL1 were overexpressed in 123 (43.0%), 43 (15.0%), and 35 (12.2%) NMIBC cases, respectively. High FATP4 in tumor cells was associated with high grade (p = 0.004) and high stage (p = 0.039). High CD36 was related to high grade (p < 0.001), high stage (p = 0.002), and non-papillary growth type (p = 0.004). High ACSL1 showed an association with high grade (p < 0.001), high stage (p = 0.01), non-papillary growth type (p = 0.002), and metastasis (p = 0.033). High FATP4 was an independent factor predicting short overall survival (OS) (hazard ratio = 3.32; 95% confidence interval, 1.07–10.31; p = 0.038). In conclusion, upregulation of FATP4, CD36, and ACSL1 might promote the NMIBC progression and could be exploited in clinical risk stratification and targeted therapy.

Abstract
Chalcone [(E)-1,3-diphenyl-2-propene-1-one], a small molecule with α, β unsaturated carbonyl group is a precursor or component of many natural flavonoids and isoflavonoids. It is one of the privileged structures in medicinal chemistry. It possesses a wide range of biological activities encouraging many medicinal chemists to study this scaffold for its usefulness to oncology, infectious diseases, virology and neurodegenerative diseases including Alzheimer's disease (AD). Small molecular size, convenient and cost-effective synthesis, and flexibility for modifications to modulate lipophilicity suitable for blood brain barrier (BBB) permeability make chalcones a preferred candidate for their therapeutic and diagnostic potential in AD. This review summarizes and highlights the importance of chalcone and its analogs as single target small therapeutic agents, multi-target directed ligands (MTDLs) as well as molecular imaging agents for AD. The information summarized here will guide many medicinal chemist and researchers involved in drug discovery to consider chalcone as a potential scaffold for the development of anti-AD agents including theranostics.

Abstract
CYP1A2 is one of the main Cytochrome P450 enzymes in the human liver associated with the metabolism of several xenobiotics. CYP1A2 is especially involved in the metabolic activation of different procarcinogens. Therefore, the development of cancer may be inhibited by inhibiting CYP1A2 activity. Here, the inhibitory effect of HYIpro-3-1 and its derivatives on CYP1A2 activity in human liver microsomes (HLM) was studied through LC-MS/MS using a cocktail assay. Among the four compounds, HYIpro-3-1 showed the most selective and strongest inhibitory effect on CYP1A2 at IC50 values of 0.1 µM in HLMs and inhibition was confirmed using purified human CYP1A2. It was determined that inhibition is reversible because the inhibitory effect of HYIpro-3-1 is not dependent on preincubation time. HYIpro-3-1 showed a typical pattern of competitive inhibition for CYP1A2-catalyzed phenacetin O-deethylation, based on the Lineweaver-Burk plot, with a Ki value of 0.05 μM in HLMs; the secondary plot also showed a linear pattern. In our study, HYIpro-3-1 was proposed as a novel inhibitor with the capacity to selectively inhibit CYP1A activity in HLMs.

Abstract
In this study, we aimed to investigate the molecular biomarkers that are pivotal for the development and progression of gastric cancer (GC). We analyzed clinical specimens using RNA sequencing to identify the target genes. We found that the expression of HOXC6 mRNA was upregulated with the progression of cancer, which was validated by quantitative real time PCR and RNA in-situ hybridization. To compare the protein expression of HOXC6, we evaluated GC and normal gastric tissue samples using western blot analysis and immunohistochemistry. We detected significantly higher levels of HOXC6 in the GC tissues than in the normal controls at both mRNA and protein levels. The expression levels of HOXC6 mRNA in patients with advanced gastric cancer (AGC) were significantly higher than those in patients with early gastric cancer (EGC). Kaplan-Meier curves showed that high expression of HOXC6 mRNA is significantly associated with poor clinical prognosis. Our findings suggest that HOXC6 mRNA may be a novel biomarker and can be potentially valuable in predicting the prognosis of GC patients. Especially, HOXC6 mRNA in-situ hybridization may be a diagnostic tool for predicting prognosis of individual GC patients.

Abstract
The derangement of the cell cycle facilitates uncontrolled cell proliferation and acquisition of genetic alterations favorable for malignancy. However, the protein expression profiles of E2 F family cell cycle regulators in clear cell renal cell carcinoma (ccRCC) have not yet been thoroughly investigated. In this study, we aimed to examine the protein expression profiles and prognostic value of E2 F1, E2 F3, and E2 F4 in ccRCC cases. The immunohistochemical expression of E2 F1, E2 F3, and E2 F4 was quantitatively scored in 180 ccRCC tumor tissues and 79 normal kidney tissues. The prognostic implications of these E2 F members were determined. We found that ccRCC tumor cells showed higher nuclear expression of E2 F1, E2 F3 and E2 F4 than normal kidney samples. High E2 F1 and E2 F3 expression in tumor cells was associated with poor prognostic factors of ccRCC, whereas high E2 F4 correlated with beneficial prognostic factors. High expression of E2 F1 and E2 F3 in tumor cells was correlated with a poor overall and recurrence-free survival, while high E2 F4 expression did not. In conclusion, E2 F1, E2 F3 and E2 F4 may function as oncogenes during tumorigenesis of ccRCC, although they contribute to the progression of ccRCC in different ways. Additional studies are required to clarify the conflicting role of E2 F4 in the tumor evolution of ccRCC.

AIM To compare the diagnostic performance of the 2017 (v2017) and 2018 versions (v2018) of the Liver Imaging-Reporting and Data System (LI-RADS) for hepatocellular carcinoma (HCC) using gadoxetic acid-enhanced magnetic resonance imaging (Gd-EOB-MRI) and to evaluate the effect in v2018. MATERIALS AND METHODS Treatment-naive patients at high-risk for HCC who underwent Gd-EOB-MRI were included. The LI-RADS categories were assigned according to v2017 and v2018. The diagnostic performances were compared between v2017 and v2018 according to the size and combination of imaging features. RESULTS A total of 117 patients with 137 observations were identified, including 89 HCCs; 76.2% (64/84) of observations with threshold growth were re-classified as subthreshold growth when using v2018 instead of v2017. The final categories changed in nine (14%) cases. For the combination of LR-5/LR-5V, there were no significant differences in sensitivity and specificity between the two versions (sensitivity, 64% versus 58.4%; specificity, 87.5% versus 85.4%; all p>0.05). For the combination of LR-4 and LR-5/5V, the diagnostic performance of v2018 was inferior to that of v2017 when considering only major features (accuracy, 86.1% versus 80.3%, respectively; p=0.013), particularly in observations measuring 10-20 mm, but was comparable after adding the ancillary features (accuracy, 86.9% versus 86.1%, respectively; p=1.00). CONCLUSION In LI-RADS v2018, although a considerable number of observations re-classified subthreshold growth, changes in the assigned categories were insignificant; overall diagnostic performance was comparable to that of v2017, but v2018 might emphasise the value of ancillary features in combination with major features for determining the probability of HCC.

Abstract
UNLABELLED Individuals with poor knowledge of osteoporosis and lower socioeconomic status, including being single and having a lower level of annual income, are less likely to be assessed or treated for osteoporosis. Individuals with particular osteoporosis risk factors such as smokers and heavy drinkers are overlooked for diagnosis. Further study is needed to identify and address the existing barriers and to promote osteoporosis management for women with these risk factors. INTRODUCTION Despite the negative health consequences of osteoporosis and the availability of effective treatment, a pervasive and persistent prevention care gap for osteoporosis remains present throughout the world. We attempted to identify the factors affecting the willingness of patients to either undergo or avoid assessment and treatment for osteoporosis. METHODS A nationwide online survey was conducted in 926 Korean women over age 50. The survey included questions addressing three domains: (1) clinical and socio-demographic characteristics, (2) questions concerning the reasons for undergoing or avoiding osteoporosis assessment or treatment, and (3) knowledge of osteoporosis as measured using the modified Korean version of Facts on Osteoporosis Quiz. The assessed and non-assessed participants were compared in terms of their clinical and socioeconomic statuses, reasons for undergoing or avoiding osteoporosis management, and levels of knowledge of osteoporosis. RESULTS The highest-ranked reason for undergoing osteoporosis assessment was fear of osteoporotic fracture, while the highest-ranked reason for avoiding osteoporosis assessment was not feeling a need to get tested for osteoporosis. Participants who sought assessment for osteoporosis were older and more likely to be married, and had greater knowledge of osteoporosis than those who did not seek assessment. The two groups were found to be similar in terms of tobacco use and daily alcohol use. Patients who had been diagnosed with osteoporosis but either did not initiate or discontinued osteoporosis treatment within 1 year were younger and had lower levels of annual income than those who began and continued treatment. CONCLUSION Individuals with poor knowledge of osteoporosis and those of lower socioeconomic status, including those who were single and had a lower level of annual income, were less likely to be assessed and treated for osteoporosis. Individuals with particular osteoporosis risk factors such as smokers and heavy drinkers are overlooked for diagnosis. Further study is needed to identify and address the existing barriers and to promote osteoporosis management for women with these risk factors.

Abstract
Occupational exposure of workers to 1-bromopropane (1-BP) has raised concerns in industry for many years. Despite the known toxicity of this chemical, molecular events attributed to exposure to 1-BP have not been extensively studied. The aim of the present study was to examine the effects of 1-BP exposure on adduct formation with DNA and glutathione (GSH) in male Sprague-Dawley rats in an attempt to determine the early stages of toxicity. Following 6 h after either single or daily exposure to 1-BP for 3 days, N7-propyl guanine and S-propyl GSH were quantified in several organs by using liquid chromatography-mass spectrometry (LC-MS/MS). The results showed that N7-propyl guanine was maximally formed in liver followed by spleen, testes, and lung in both dose- and time-dependent manners. However, DNA adduct was not detected in cardiac tissue. In the case of S-propyl GSH, this compound was formed in the following order in various organs: liver > testes > spleen > kidney > lung > heart. In a subsequent in vitro study, formation of N7-propyl guanine initiated by 1-BP in calf thymus DNA was not markedly affected by addition of liver homogenates, which indicated that this chemical may be acting as a direct alkylating agent. In contrast, an in vitro study with free GSH demonstrated that 1-BP reduced GSH and elevated production of S-propyl GSH, and that the production of this adduct was significantly higher in the presence of active liver homogenates. Data indicated that formation of GSH adducts initiated by 1-BP might be associated with an enzyme-driven process. Although further characterization is necessary, it would appear that N7-propyl guanine and S-propyl GSH might serve as useful markers in cases of exposure assessment of 1-BP.

Abstract
Abstract
Purpose: Conditional relative survival (CRS) could provide more relevant information on the current prognosis of cancer survivors than standard 5-year relative survival (RS). This study aimed to estimate the 5-year CRS of Korean breast cancer patients.
Patients and Methods: We identified 145,083 breast cancer cases with diagnosis between 2002 and 2013 in the Korea Central Cancer Registry. The CRS was estimated for every year after diagnosis, according to sex, age, histologic types, stage, and year of diagnosis.
Results: The 5-year RS at diagnosis was 90.8% and 10-year RS was 85.7%. Five-year CRS was 91.0% and 94.3% at 1-year and 5-year after diagnosis. Women had better 5-year CRS than men after 5 years of survival (94.3% vs. 79.5%), and very young and very old patients had worse 5-year CRS after 5 years of survival than other age groups (92.2% in <40yr, 92.6% in ≥70yr vs. 95.4% in 40-49, 94.3% in 50-59, and 93.7% in 60-69, relatively). In histologic types, CRS of metaplastic carcinoma has improved from 82.0% to 95.2%, compared to CRS of lobular carcinoma (from 93.1% to 92.5%). Hardly any excess mortality (5-year CRS ≥ 95%) was seen since 7 years after diagnosis. There was hardly any excess mortality at 5 years of survival, for the patients with 40-49 years (95.4%), with localized disease (97.8%), and with metaplastic carcinoma (95.2%).
Conclusion: This study showed that CRS of breast cancer survivors in Korea has been improved, which varied by sex, age, stage, and histologic types. These CRS analysis could provide a more detailed information for survival to breast cancer survivors and clinicians.

Abstract
Abstract
BACKGROUND
Assessment of restoration of ovarian function after chemotherapy is critical with respect to the initiation of different types of endocrine treatment in young high risk breast cancer patients
METHODS
In total, 1289 women who remained premenopausal or resumed premenopausal status after chemotherapy were randomized to receive 5 years of tamoxifen or 5 years of tamoxifen plus 2 years of ovarian suppression. The patients who did not resume menstruation were followed up for 2 years with tamoxifen treatment after finishing chemotherapy. Prospectively collected consecutive post-chemotherapy hormone and menstruation data were available for 705 breast cancer patients who enrolled tamoxifen-only treatment group or did not resume menstruation during follow up. This analysis evaluated the proportion of patients with pre-menopausal FSH levels (<30 mIU/ml), E2 levels (340 pg/ml), and menstruation at any time point during treatment with tamoxifen.
RESULTS
During 5 years of tamoxifen treatment after chemotherapy for premenopausal breast cancer patients, 62% of patients resumed menstruation. Menstruation returned in 92% of patients under 35 years old but only in 31% of patients over 45 years old. Ovarian function, defined by serum FSH and E2 levels, resumed in 94% and 65% of patients, respectively, over 5 years. Most patients achieved ovarian function restoration during the first 2 years after chemotherapy, with 47.1% resuming menstruation and 86.2% and 50.3% achieving pre-menopausal FSH and E2 levels, respectively, in the first 2 years. Clinical factors related to menstruation restoration were younger age (HR = 6.38, 95% CI 1.33-3.47), 6 month hormone profile after chemotherapy (FSH<30: HR=1.67, 95% CI 1.28-2.17; E2 >40: HR=2.96, 95% CI 2.25-3.89), and anthracycline without taxane chemotherapy (HR=1.63, 95% CI 1.25-2.13).
CONCLUSIONS
During 5 years of tamoxifen treatment after chemotherapy, half of patients experienced menstruation restoration, including most very young patients under 35 years. The majority of patients experienced menstruation restoration in the first 2 years of tamoxifen treatment.

Abstract
BACKGROUND The standard diagnostic test for allergic contact dermatitis is the patch test, which can also be used to identify irritant contact dermatitis. Doubtful reactions (?+) can be often clinically relevant to individuals and can require additional tests. OBJECTIVES The purpose of this study was to examine whether autofluorescence (AF) measurements in patients with doubtful reactions are helpful in diagnosing contact dermatitis. METHODS Patients with a history of contact dermatitis were patch tested on the upper back for 48-hours of occlusion using aqueous solutions of 5% sodium lauryl sulfate. Reaction intensity was scored, and AF was measured on reactive lesions and non-lesions. Three dermatologists classified the results as positive or negative using the fluorescence photographs of patients with a doubtful reaction. RESULTS Among doubtful reactions, the R/G% values were significantly higher in the AF- based positive group than in the negative group (P = .0086). On the other hand, the heterogeneity values of R, G, and B (HR, HG, HB) were significantly lower in the AF-based positive group (P = .0026, .0046, .0004 respectively). CONCLUSIONS Measuring AF along with the clinical readings can help confirm doubtful patch test reactions.

Abstract
Abstract
BACKGROUND
Risk-reducing (RR) management decreases the risk of breast cancer and BRCA related gynecologic cancer. However, there are fewer reports on the RR management in Asia compared to Western countries.The aim of this study is to identify risk reducing management patterns with BRCA1 or BRCA2 mutation carriers.
METHODS
The study group consisted of all consecutive 1104 breast cancer, ovarian patients and their families of high-risk patients who underwent BRCA gene testing in National Cancer Center, Korea from 2008 to 2016. A total 220 BRCA mutations (19.9%) were detected with 125(11.3%) of BRCA1 gene and 95 (8.6%) of BRCA2 gene.
RESULTS
Out of 220 BRCA mutations carriers, they were consisted of 83 breast cancers, 10 ovarian cancers, 7 both cancers, and 120 unaffected carriers. Among them, 42 were men and 178 were women. About 90 % (198/ 220) had the familial history of breast, ovarian or both malignancies (113 in BRCA1 and 85 in BRCA2 mutation (p=0.821)).
All 42 men chose surveillance. Among 178 female BRCA mutation carriers, 98(55.1%) underwent risk reducing management including 18(10.1%) of chemoprevention, and 80(49.9%) had risk-reducing surgeries (RRSs) (1 case of risk-reducing mastectomy, 76 of risk reducing bilateral salphingo-oophorectomy (RRSO), and 3 of both) and 80 (54.9%) chose only intensive surveillance for both of breast and ovary cancer.
In affected carriers with breast cancer, 59 (71.1%) underwent RR management (1 case of risk reducing mastectomy, 53 of RRSO, 3 of both surgery, and 2 of chemoprevention). There was no risk reducing management in affected carrier with ovarian cancer patients. In 78 unaffected women carriers, 39(50.0%) women received RR management (23(29.5%) cases of RRSO and 16(20.5%) cases of chemoprevention). The rates of RRSs have increased annually since the 2013 year, (prior to 2013 vs. since 2013, RRSs 28.6% (6 cases/21 carriers) vs. 37.2% (74/199), p<0.01).
CONCLUSION
This study was conducted on the largest numbers of BRCA mutation carriers in Asian countries. RRSO is the more preferred management for affected carriers with breast cancer or unaffected carriers. The results might be explained by the severity of the illness and that RRSO was only reimbursed RR strategy from the Korean Government Insurance. Tailored genetic counseling and insurance policy may enhance overall levels of RR management.

Abstract
Bulimia nervosa is one of the eating disorders. Psychological manifestations of this disease, such as guilt or denial, may interfere with patient communication. The patients with bulimia nervosa are most commonly between ages of 17 and 25 years old, and often maintain normal body weight. It is not easy to screen out and diagnose bulimia nervosa patients at the emergency department. We reported two bulimia nervosa patients who visited our emergency department with abdominal distension, and one of them died of abdominal compartment syndrome. We confirmed collapse of the abdominal aorta and key arteries in enhanced abdominal computed tomography. Promptly, we performed gastrostomy for reduction of abdominal pressure, but she finally succumbed due to multiple organ failure 12 hours after the surgery.

Abstract
Nanoparticle-based drug delivery systems are designed to reach tumor sites based on their enhanced permeation and retention effects. However, a lack of interaction of these nanoparticles with cancer cells might lead to reduced uptake in the tumors, which might compromise the therapeutic efficacy of the system. Therefore, we developed bortezomib and IR-820-loaded hybrid-lipid mesoporous silica nanoparticles conjugated with the hydrophobic-binding peptide, cyclosporine A (CsA), and referred to them as CLMSN/BIR. Upon reaching the tumor site, CsA interacts hydrophobically with the cancer cell membranes to allow effective uptake of the nanoparticles. Nanoparticles ∼160 nm in size were prepared and the stability of IR-820 significantly improved. High cellular uptake of the nanoparticles was evident with pronounced apoptotic effects in PANC-1 and MIA PaCa-2 cells that were mediated by the chemotherapeutic effect of bortezomib and the photothermal and reactive oxygen species generation effects of IR-820. An in vivo biodistribution study indicated there was high accumulation in the tumor with an enhanced photothermal effect in PANC-1 xenograft mouse tumors. Furthermore, enhanced antitumor effects in PANC-1 xenograft tumors were observed with minimal toxicity induction in the organs of mice. Cumulatively, these results indicated the promising effects of CLMSN/BIR for effective chemo-phototherapy of pancreatic cancers.

Abstract
OBJECTIVE This study aimed to investigate excessive Internet use's (EIU's) association with oral health behaviors among Korean adolescents. BASIC RESEARCH DESIGN This cross-sectional study was based on the 11th Korea Youth Risk Behavior Web-based Survey (2015). PARTICIPANTS 68,043 school students aged 13-18 years (35,204 boys and 32,839 girls). Data on, 45,271 (23,354 males and 21,917 females using the Internet on weekdays) and 49,324 (27,448 males and 21,876 females using the Internet on weekends) were analyzed after excluding questionnaires with missing values. MAIN OUTCOME MEASURES The key variables were oral health behaviors (tooth-brushing frequency and tooth brushing after lunch at school, and preventive oral health behaviors), EIU (hours of Internet use on weekdays and weekends, excluding use for academic purposes). RESULTS Compared to the general groups, the odds ratio (OR) for less tooth-brushing was 4.04 (95%CI=2.990-5.459) and 3.55-fold higher (95% CI=2.703-4.659) in the high-risk groups for weekday and weekend EIU, respectively. For post-lunch tooth-brushing, compared to the general groups, the OR for less tooth-brushing was 1.7-fold higher in the high-risk groups for EIU during weekdays and weekends. The OR for no preventive behavior was significantly higher in the high-risk groups than in the potential-risk and general groups. CONCLUSIONS Policies moderating adolescents' EIU may enable appropriate oral health behaviors.

Abstract
Non-alcoholic fatty liver disease and non-alcoholic steatohepatitis are characterized by an increase in hepatic triglyceride content with infiltration of immune cells, which can cause steatohepatitis and hepatic insulin resistance. C-C chemokine receptor 7 (CCR7) is primarily expressed in immune cells, and CCR7 deficiency leads to the development of multi-organ autoimmunity, chronic renal disease and autoimmune diabetes. Here, we investigated the effect of CCR7 on hepatic steatosis in a mouse model and its underlying mechanism. Our results demonstrated that body and liver weights were higher in the CCR7−/− mice than in the wild-type (WT) mice when they were fed a high-fat diet. Further, glucose tolerance and insulin sensitivity were markedly diminished in CCR7−/− mice. The number of invariant natural killer T (iNKT) cells was reduced in the livers of the CCR7−/− mice. Moreover, liver inflammation was detected in obese CCR7−/− mice, which was ameliorated by the adoptive transfer of hepatic mononuclear cells from WT mice, but not through the transfer of hepatic mononuclear cells from CD1d−/− or interleukin-10-deficient (IL-10−/−) mice. Overall, these results suggest that CCR7+ mononuclear cells in the liver could regulate obesity-induced hepatic steatosis via induction of IL-10-expressing iNKT cells.

Abstract
Abstract
INTRODUCTION
Axillary sentinel lymph node (SLN) biopsy is a standard method for axillary nodal staging in the treatment of breast cancer. However, along with the trends to SLN performed only without additional axillary lymph node dissection, it's time to be considered omission of SLN for selective patients. We developed a prediction model to assess the negative probability of sentinel lymph node metastasis, specifically focus on the patients with clinical T1 breast cancer.
METHODS and MATERIALS
The study group consisted of 513 consecutive patients with clinical T1 breast cancer, who had undergone primary surgery between 2007 and 2012. The clinicopathologic factors and imaging modalities including breast ultrasound (US), magnetic resonance imaging (MRI), chest computed tomography (CT), and positron emission tomography (PET) were evaluated. Patients who fulfilled our inclusion criteria were randomized into experimental and validation set by 3:1 ratio. In the experimental group (n = 256), multivariate logistic regression analysis was used to analyze the association of each variable with the likelihood of SLN metastases. A prediction model was developed based on the patients in the experimental group and was validated with internal patient cohorts.
RESULTS
Of the 513 patients, 119 (23.1%) were found to have SLN metastases. In univariate analysis, presence of lymphovascular invasion (P < 0.001) and suspicious finding of preoperative image studies (US, PET, and MRI, P < 0.001) were independent positive predictors of SLN metastases. In multivariate analysis of experimental group, estrogen receptor status (P = 0.012), presence of lymphatic invasion (P < 0.001), and suspicious finding of preoperative image studies (US, PET, and MRI, P < 0.001) were each associated with involvement of SLN. A prediction model based on this analysis consists of 9 rows including 6 variables (age, estrogen receptor status, presence of lymphatic invasion, and results of preoperative US, PET or CT, MRI). The sum of assigned points for all six variables made corresponding value of negative probability of SLN metastasis. The accuracy of prediction model applied to the validation group, as measured by the area under the receiver operating curve was 0.789.
CONCLUSIONS
The prediction model developed here may be a useful tool to assess SLN involvement for clinical T1 breast cancer patients. And prospective study for additional validation of the prediction model is currently in preparation, exploring the possibility of SLN biopsy omission.

Abstract
Our aim was to compare the postoperative stability of the mandible when two different fixation methods had been used after bilateral sagittal split ramus osteotomy (BSSRO) for mandibular setback. The study included 23 patients who had two-jaw BSSRO mandibular setback at the Department of Oromaxillofacial Surgery, Korea University Guro Hospital, between January 2011 and June 2014. The first group (four-hole (control) group, n=13) comprised patients whose bony segments were fixed with conventional four-hole plates, and the second (sliding plate (experimental) group, n=10) included patients whose bone segments were fixed with sliding plates. Lateral cephalograms were taken and analysed at three time points: preoperatively (T1), and one week (T2), and 1year (T3) postoperatively. The Mann-Whitney U test was used to compare the postoperative stability of the mandible in each group. There were no significant differences between the two groups in changes in the horizontal and vertical positions of point B and pogonion postoperatively, nor were there any significant differences between them in ramal inclination and inclination of the SN plane with point B at the given time points (p=>0.05 in surgical changes in the mandible immediately after surgery and 0.397, 0.616, 0.082, 0.951, 0.901, 0.476 in postoperative changes in the mandible 1 week to 1 year after surgery). Like the conventional four-hole plate, the sliding plate can also be used to achieve stability in the fixation of mandibular bone segments after BSSRO.

Abstract
AIM The aim of this study was to assess the effects of ursodeoxycholic acid composite (URSA-S) on fatigue in patients with elevated liver function tests and/or fatty liver disease. METHODS In this multi-centre randomised double-blinded placebo-controlled trial, 168 adults who were diagnosed with fatigue based on our criteria and had elevated liver function tests (but not > 5 times the normal level) and/or fatty liver on ultrasonography, were randomised to either the placebo or URSA-S administration group. The rate of improvement of checklist individual strength (CIS) using a cut-off of 76 points at the end of the study (8 weeks), the change in fatigue scale [CIS score and visual analogue scale (VAS)] were evaluated. The adverse effects of URSA-S were also recorded. RESULTS The rate of CIS improvement at the end-point was 79.76% and 45.68% in the therapy and placebo groups, respectively (p < 0.05). The fatigue recovery rate of the CIS score and VAS were higher in the therapy (-25.44 ± 18.57, -27.84 ± 2.70) than in the placebo group (-16.59 ± 17.29, -19.46 ± 2.81) (p < 0.05). The difference in fatigue recovery rate between the therapy and placebo groups was significant after 8 weeks. When analysed separately in patients with abnormal liver function tests and fatty liver disease, the fatigue recovery rate of the CIS score and VAS at 8 weeks was higher in the therapy than in the placebo group (p < 0.05). The frequency of adverse events in the therapy group was not significantly higher than that in the placebo group. CONCLUSION URSA-S is effective for alleviating fatigue in patients with liver dysfunction and/or fatty liver. The adverse effects of URSA-S are not significant. This study is registered at https://clinicaltrials.gov/ct2/show/NCT02415777.

Abstract
Abstract
Background: Recently, chemotherapy with a GnRH agonist was reported to protect against ovarian failure. This study was aimed at determining the oncologic effect of a GnRH agonist concurrent with chemotherapy for breast cancer patients.
Patients and Methods: A total of 1189 patients aged 20 to 40 years with stage I to III breast cancer who received (neo or adjuvant) chemotherapy from five hospitals in Korea from 2002 to 2012 were reviewed. A gonadotropin releasing hormone (GnRH) agonist was given to 410 patients for ovarian protection during chemotherapy (GnRH agonist group), and 779 patients received chemotherapy without ovarian protection (Chemotherapy alone group). A matching strategy was used to create matched sets of two groups by age, stage, hormone receptor status, Her2/neu status, neo or adjuvant chemotherapy, and institute.
Results: Survival analysis using Cox regression showed that the GnRH agonist group had better distant metastatic-free survival (HR=0.65, 95%CI 0.44-0.97) outcomes but similar disease free survival (HR=0.78, 95% CI 0.57-1.08) compared with the chemotherapy alone group. The survival benefit was significant for hormone receptor positive, Her2/neu negative breast cancer on distant metastasis (HR=0.44, 95% CI 0.20-0.99) and disease free survival (HR0.47 95% CI 0.23-0.93).
Conclusion: Ovarian protection using a GnRH agonist can be safely considered for premenopausal breast cancer patients for whom chemotherapy is planned.

Abstract
Abstract
Background: Ki-67 has been increasingly used as a prognostic marker in spite of debates on the evaluation methods and inconsistent results on its clinical values. CKAP2 is a microtubule-associated protein which plays key roles in microtubule assembly and disassembly. In the present study, the clinical significance of CKAP2-positive cells was evaluated and compared with the results of Ki-67 positive cells.
Methods: A total of 579 early breast cancer patients who underwent surgery at the National Cancer Center Hospital between 2001 and 2005 were accrued. The proliferation activity was measured by CKAP2-positive cell count (CPCC) and Ki-67 labeling index (Ki-67 LI) using CKAP2 and Ki-67 antibodies, respectively, by immunohistochemcial staining on FFPE tumor tissue. The correlation of CPCC or Ki-67 LI with recurrence free survival (RFS) was analyzed. The immunofluorescent staining was performed on HeLa cells after synchronization by double thymidine block to compare the patterns between CKAP2 and Ki-67.
Results: The CPCC (median, 8 with the range of 0- 170) and Ki-67 LI (median, 10.2 with the range of 0%- 91.7%) were highly correlated (R = 0.754, P < 0.001). While CPCC was marginally significant in multivariate analysis for RFS in all cases, it was a significant variable for RFS in the subset analysis with HER2-negative luminal breast cancer patients (HR, 3.154; 95% CI, 1.154-10.693; P = 0.027). On the contrary, Ki-67 LI failed to show any correlation with RFS in all or any subgroups. In the analysis on HeLa cells, CKAP2 staining was more specific to cells in metaphase than Ki-67 staining.
Conclusions: CPCC can be an independent prognostic factor specifically in a HER2-negative luminal type of breast cancer. In addition, CPCC appears to be superior to Ki-67 LI as a survival indicator which may be related to the restricted expression pattern of CKAP2 in metaphase cells. Further study is warranted.

Abstract
Abstract
Background/purpose: The number of long-term breast cancer survivors is increasing rapidly due to the growing rates of detection, incidence and improved survival. Quality of life (QOL) of physical and psychosocial health outcomes vary across the breast cancer survivors including diagnosis at different stages of breast cancer. There is little data regarding the psychosocial health of disease-free breast cancer survivors compared with those of general population. We conducted to assess the QOL, especially psychosocial health, of disease-free female survivors over 2 year after breast cancer diagnosis compared with cancer-free control women.
Methods: We used baseline data from the health examinee cohort, a part of the Korea Genome Epidemiology Study which is a large scaled cohort study established since 2001. This cohort has collected data of past medical history, socioeconomical factors (income, education, marital status and current employment status) and health behavioral factors (smoking, drinking, physical activity, BMI, menopausal status and subjective health status) of participants while they underwent regular health examination. The disease-free breast cancer survivors were defined as those who answered that they were ≥2 years from the initial diagnosis of breast cancer without recurrence and current treatment. Among the participants female subjects without history of any type cancer were randomly selected at 1:4 ratio by 5-year age groups, educational attainment level and household income as a comparison group. We analyzed Psychosocial Well-being Index-Short Form (PWI-SF) in these two groups. Subjects with score ≤8, 9–26, and 27 were classified as the 'healthy group', 'latent stress group', and 'stress group,' respectively.
Results: Total 347 survivors of breast cancer and 1,388 matched participants without cancer history were selected for analysis. Even after being matched for education and household income status, breast cancer survivors showed better psychosocial health status and health behaviors compared with matched comparison group. The prevalence of latent stress and stress group (vs healthy group) by PWI-SF score was 88.2% in breast cancer survivors and 89.9% in the matched female controls, showing borderline significant differences (p = 0.057). The prevalence rates of ever drinkers and smokers or obese women were lower and of those who exercised ≥150 min/week were higher in breast cancer survivors (p < 0.05). The total PWI-SF score was lower in breast cancer survivors, suggesting lower level of psychosocial stress level in breast cancer survivors. After adjusting for effects of other sociodemographic variables, breast cancer survivors were less likely to be included in stress group by 36% (OR = 0.64; 95% confidence interval [CI], 0.42–0.98).
Conclusions: The disease-free breast cancer survivors with regular health examination showed better psychosocial health status compared with matched general population. The better health behaviors in cancer survivors such as less alcohol drinking, low BMI, less history of smoking and more regular exercise, which have been identified in several previous cancer survivors studies might be attributed to their better psychosocial health status.

Abstract
BACKGROUND We aimed to develop a prediction model to identify long-term survivors after developing distant metastasis from breast cancer. PATIENTS AND METHODS From the institution's database, we collected data of 547 patients who developed distant metastasis during their follow-ups. We developed a model that predicts the post-metastasis overall survival (PMOS) based on the clinicopathologic factors of the primary tumors and the characteristics of the distant metastasis. For validation, the survival data of 254 patients from four independent institutions were used. RESULTS The median duration of the PMOS was 31.0 months. The characteristics of the initial primary tumor, such as tumor stage, hormone receptor status, and Ki-67 expression level, and the characteristics of the distant metastasis presentation including the duration of disease-free interval, the site of metastasis, and the presence of metastasis-related symptoms were independent prognostic factors determining the PMOS. The association between tumor stage and the PMOS was only seen in tumors with early relapses. The PMOS score, which was developed based on the above six factors, successfully identified patients with superior survival after metastasis. The median PMOS for patients with a PMOS score of <2 and for patients with a PMOS score of >5 were 71.0 and 12 months, respectively. The clinical significance of the PMOS score was further validated using independent multicenter datasets. CONCLUSIONS We have developed a novel prediction model that can classify breast cancer patients with distant metastasis according to their survival after metastasis. Our model can be a valuable tool to identify long-term survivors who can be potential candidates for more intensive multidisciplinary approaches. Furthermore, our model can provide a more reliable survival information for both physicians and patients during their informed decision-making process.

Abstract
Leptin, a hormone mainly produced from adipose tissue, has been shown to induce proliferation of cancer cells. However, the molecular mechanisms underlying leptin-induced tumor progression have not been clearly elucidated. In the present study, we investigated the role of autophagy in leptin-induced cancer cell proliferation using human hepatoma (HepG2) and breast cancer cells (MCF-7), and tumor growth in a xenograft model. Herein, we showed that leptin treatment caused autophagy induction as assessed by increase in expression of autophagy-related genes, including beclin-1, Atg5 and LC3 II, further induction of autophagosome formation and autophagic flux. Interestingly, inhibition of autophagic process by treatment with inhibitors and LC3B gene silencing blocked leptin-induced increase in cell number and suppression of apoptosis, indicating a crucial role of autophagy in leptin-induced tumor progression. Moreover, gene silencing of p53 or FoxO3A prevented leptin-induced LC3 II protein expression, suggesting an involvement of p53/FoxO3A axis in leptin-induced autophagy activation. Leptin administration also accelerated tumor growth in BALB/c nude mice, which was found to be autophagy dependent. Taken together, our results demonstrate that leptin-induced tumor growth is mediated by autophagy induction and autophagic process would be a promising target to regulate development of cancer caused by leptin production.

Abstract
Slow-release permanganate (MnO4(-)) gel (SRP-G) is a hyper-saline KMnO4 solution that can be used for treating large, dilute, or deep plumes of chlorinated solvents in groundwater. Ideally, the SRP-G injected into aquifers will slowly gelate to form MnO4(-) gel in situ, and the gel will slowly releases MnO4(-). Objectives of this study were to develop SRP-G using colloidal silica as gelling solution, characterize its gelation and release kinetics, and delineate its dynamics in a saturated sandy media. The SRP-G exhibited a two-phase increase in viscosity: a lag phase characterized by little increase in viscosity followed by a short gelation phase. Gelation lag times of SRP-G solutions increased (from 0.5h to 13d) with decreasing KMnO4 concentrations (from 25 to 8 g L(-1)). Permanganate release from gelated SRP-G increased with increasing KMnO4 concentrations, and was characterized as asymptotic release with initial peak (0.9-2.2 mg min(-1)) followed by more attenuated release. Gelation lag times of SRP-G flowing in sands (linear velocity=2.1md(-1)) increased (1, 3, and 6h) with decreasing KMnO4 concentrations (25.0, 23.0, and 22.9 g L(-1)). Permanganate release from gelated SRP-Gs continued for up to 3d and was characterized as asymptotic release with an initial peak release (∼1.2 g min(-1)) followed by more attenuated release over 70h. Dilution of SRP-G by dispersion in porous media affects gelation and release kinetics. Increasing the silica concentration in the SRP-G may facilitate gelation and extend the duration of MnO4(-) release from emplaced SRP-G in porous media.

Abstract
This study was conducted to determine how the isolation method of the porcine preantral follicles influenced the following follicular growth in vitro. Mechanical and enzymatical isolations were used for retrieving the follicles from prepubertal porcine ovaries, and in vitro-growth of the follicles and the expression of folliculogenesis-related genes were subsequently monitored. The enzymatic retrieval with collagenase treatment returned more follicles than the mechanical retrieval, while the percentage of morphologically normal follicles was higher with mechanical retrieval than with enzymatic retrieval. After 4 days of culture, mechanically retrieved, preantral follicles yielded more follicles with normal morphology than enzymatically retrieved follicles, which resulted in improved follicular growth. The mRNA expression of FSHR, LHR Cx43, DNMT1 and FGFR2 genes was significantly higher after culture of the follicles retrieved mechanically. These results suggest that mechanical isolation is a better method of isolating porcine preantral follicles that will develop into competent oocytes in in vitro culture.

Abstract
Permanganate (MnO4(-)) is a strong oxidant that is widely used for treating chlorinated ethylenes in groundwater. This study aims to develop hyper-saline MnO4(-) solution (MnO4(-) gel; PG) that can be injected into aquifers via wells, slowly gelates over time, and slowly release MnO4(-) to flowing water. In this study, compatibility and miscibility of gels, such as chitosan, aluminosilicate, silicate, and colloidal silica gels, with MnO4(-) were tested. Of these gels, chitosan was reactive with MnO4(-). Aluminosilicates were compatible but not readily miscible with MnO4(-). Silicates and colloidal silica were both compatible and miscible with MnO4(-), and gelated with addition of KMnO4 granules. Colloidal silica has low initial viscosity (<15cP), exhibited delayed gelation characteristics with the lag times ranging from 0 to 200min. Release of MnO4(-) from the colloidal silica-based PG gel occurred in a delayed fashion, with maximum duration of 24h. These results suggested that colloidal silica can be used to create PG or delayed-gelling forms containing other oxidants which can be used for groundwater remediation.

Abstract
SUMMARY OBJECTIVE To investigate gender and age difference in impact of overweight on health-related quality of life (HRQOL) among Korean adults. METHODS Cross-sectional obesity-related quality of life (QOL) scores were measured by a Korean obesity-related QOL scale (KOQOL) from 448 Korean adults aged 20-80 years. A body mass index (BMI) was categorized with normal-weight as BMI < 23 kg/m(2), overweight as BMI ≥ 23 kg/m(2) based on the alternative cutoff points for Asians. Each gender was respectively stratified by median age, 45 years for men and 50 years for women, to examine the obesity-related QOL by age groups. RESULTS Women had a poorer obesity-related QOL compared to men (p < 0.001). In the younger age group, overweight women had a poorer obesity-related QOL compared with normal-weight women (p < 0.001), however normal-weight and overweight men showed no difference in obesity-related QOL. In the older age group, overweight men showed better QOL on the domains of work-related and psychosocial health than those for normal-weight men, but overweight women still suffered from work-related and routine life QOL. CONCLUSIONS This study showed the impact of overweight on obesity-related QOL was different for gender and age group. We should consider the results to manage weight in overweight persons.

Abstract
Abstract
Background: Recent data from ACOSOG Z0011 trial or AMAROS trial suggest that axillary lymph node dissection(ALND) may be unnecessary for patients with positive sentinel lymph node biopsy(SLNB) receiving breast conserving surgery(BCS) with irradiation. However, consensus statements and guidelines until recently recommended that patients with mastectomy and tumor positive sentinel node undergo completion ALND. In this preliminary study, we compared these patients who did not undergo ALND with the patients who received BCS with SLNB only and irradiation and we analyzed the locoregional recurrence rate to show no differences of outcomes between two groups.
Method: We identified 6,163 women with invasive breast cancer who underwent surgical resection at the National Cancer Center (Goyang,Gyeonggi-do,Korea) between January 2000 to December 2011. Clinico-pathological data obtained from prospective collecting medical database of our institution were analyzed retrospectively. The mastectomy with positive SLNB group was 47 patients and BCS with positive SLNB and irradiation group was 172 patients. The primary end point was loco-regional recurrence rate.
Result : Clinical and tumor characteristics were similar between two groups except T stage and receptor status. The mean tumor size was 5.5cm with mastectomy group and 3.5cm with BCS group. The median number of nodes removed was three. There was not a single case of locoregional recurrence in both groups. At a median follow-up of 53.5 months (last follow-up, May 2013), 5-year overall survival was 85.7% with mastectomy and 97.3% with BCS group.
Conclusion : In our study, there was no case of locoregional recurrence as above. This results lend weight to the argument that SLNB without ALND may be reasonable management for selected patients with appropriate surgery and adjuvant systemic therapy. This study can be regarded as a preliminary study with a sufficient value despite of the prognosis showed some statistical differences between two groups. It resides in the difference of initial stage of patients of two groups. We will present additional data compared with the mastectomy with axillary clearance group at the meeting.

Abstract
Abstract
BACKGROUND: Primary squamous cell carcinoma of the breast (PSCCB) is one of the rarest forms of breast cancer, accounting for less than 0.1% of all breast cancers. PSCCB can be aggressive with no typical radiologic findings on mammogram, often leading to delays in diagnoses or missed diagnoses. Previously reported cases of PSCCB have illustrated a wide range of clinical presentations, from an abnormal mammogram with no obvious breast mass to a breast abscess. In addition, due to the rarity of this disease, no clear consensus on definitive treatment or prognosis exists.
METHODS: Using a search of our pathology database, we identified females diagnosed with PSCCB at our institution from 2007-2012. Inclusion criteria included female patients over the age of 18 years old with a primary tumor consisting of >90% malignant cells of squamous origin. Likewise, exclusion criteria included squamous cell cancer that had metastasized to the breast from elsewhere or lesions that were not independent of the overlying skin or nipple. We then performed a retrospective review to evaluate patient characteristics, presentation, tumor characteristics, treatment modalities and outcomes.
RESULTS: We identified three patients who were diagnosed with PSCCB during that timeframe. Their ages ranged from 35-65 years old, with two being post-menopausal and one pre-menopausal. Of the three, two were Caucasian and one was Hispanic. All three presented after self-palpating a breast mass. The average size of the mass seen on mammogram was 2.9 cm (range of 2.4 to 3.6 cm). Histologically, all three of the cancers were moderately to poorly differentiated. In addition, they all had a negative estrogen, progesterone, and HER2 receptor status with an elevated Ki-67. One patient was diagnosed at our institution but did not proceed to surgery and was lost to follow up. For the other two patients, one chose to undergo breast conservation with partial mastectomy and sentinel lymph node biopsy followed by whole breast radiation. The second patient proceeded with a total mastectomy and sentinel lymph node biopsy without radiation. There was no evidence of regional nodal disease in either patient at time of surgery. Furthermore, neither patient received any systemic therapy. Both patients were disease free at last follow up which was 5 and 11 months respectively.
CONCLUSION: Because PSCCB is so rare, prognosis and optimal treatment are still controversial. Most of the current literature portrays PSCCB as an aggressive cancer with a poor prognosis. This often leads to multimodality therapy consisting of mastectomy with axillary nodal clearance, adjuvant chemotherapy and radiation. In addition, locoregional and distant recurrences are common despite this aggressive treatment leading to the conclusion that PSCCB is relatively radioresistant with limited activity seen when using conventional breast cancer systemic therapies. Because treatment options can be limited, more research is needed to further elucidate the biological behavior of this rare cancer as well prognostic factors that may allow us to treat a patient more conservatively.

Abstract
Abstract
Background: The downstaging of the primary tumor and the increase in breast conservation rates seems to be the only clinical benefit of Neoadjuvant systemic therapy(NST) in breast cancer treatment, given that several studies failed to demonstrate an improvement of overall survival compared with postoperative adjuvant chemotherapy. In Europe, S6 trial showed better early outcome in survival in favour of the neoadjuvant chemotherapy group compared to adjuvant chemotherapy group in premenopausal patients without significantly modifying long-term event rates. The aim of this study was to assess a potential advantage in survival by neoadjuvant as compared to adjuvant chemotherapy in young age breast cancer patients.
Methods: Between January 2001 and December 2008, 1169 consecutive patients with breast cancer aged under 40 underwent adjuvant chemotherapy before or after surgery. Prospectively collected medical records for all patients were reviewed retrospectively. For the comparison of survival between neoadjuvant versus adjuvant chemotherapy group, cinically T2 and node positive patients were retrieved. Survival curves were derived from Kaplan-Meier estimates and compared by log-rank test.
Results: Of the 1169 patients, 203(17.3%) patients were treated with neoadjuvant chemotherapy, and they were grouped as ‘NST’ and ‘non-NST’ according to initial treatment. About 47% patients in each group were clinically T2 patients. (99(47.8%) in NST group, 453(46.9%) in non-NST group) Among them, clinically T2 and node positive patients were 188, 97 patients in NST group, 91 patients in non-NST group each. The median age was 35.11±3.9 years old and HER2 amplification was observed as 23.5%, and they were not different between two groups.(p = 0.146 and 0.941 each) Significant lower hormone receptor expression rate and higher Ki-67 level were observed in NST group(p = 0.03 and <0.0001 each) Breast conservation surgery rate was also significantly different between two groups, more favorable results in NST group.(67% in NST group, 37.4% in non-NST group, p<0.0001) During median follow-up period of 61 months (range 44 to 148 months), we observed a statistically significant difference (p = 0.011) in survival in favour of the NST group. This benefit of survival was presented consistently regardless of hormone receptor expression. A similar trend was seen when the time to distant disease recurrence was evaluated (p = 0.176). And this trend was more prominent in hormone receptor negative patients, but still not statistically significant. (p = 0.144) The mean total dose of chemotherapy administered was similar in both groups. Improved survival figures in the NST group could be the result of the early initiation of systemic treatment, but the trend in favour of decreased metastases was not statistically significant.
Conclusion: A potential advantage of primary over adjuvant chemotherapy in young age breast cancer patients’ survival might be proposed by this results.

Abstract
Abstract
Introduction: Many somatic mutations, structural alterations, and gene expression changes are causally implicated in oncogenesis and tumor progression, and as a result, affect clinical outcome. Although majority of breast cancer patients have benefits from therapeutics targeting tumor biology, such as estrogen receptor and HER-2, still many patients suffer from disease recurrence and metastasis. More kind of specific target therapies are needed, especially for hormone-resistant tumor and triple-negative breast cancer.
Materials and Method: To find novel therapeutic target in breast cancer, here we examine the both whole exome and whole transcriptome of fresh-frozen primary breast cancer tissues from 120 patients whose clinical, pathological, and survival data are available. Patients with Stage IV disease or who received neoadjuvant chemotherapy were excluded. 36 patients had distant metastasis within 5 years from surgery, and 84 patients were NED at least 5 years. RNA and DNA were extracted and qualities were assessed in all samples. Exome and transcriptome sequencing were done using NGS technology (Illumina HiSeq 2000). As a control, exome sequencing was done for 93 normal DNA from matched patients. Single nucleotide variations (SNV) identified in cancer samples on exonic region, nonsynonymous SNV or stop gain/loss, whose quality ≥20, and not found in 93 normal samples were included. SNVs registered in dbSNP135_common or 1000 genome allele frequency >0.001 were excluded.Results and Discussion: We identified 11,684 putative somatic mutations in 7,373 genes. Of them, 6,547 were deleterious or damaging mutation by Provean or SIFT analysis. Mutations were found in potential drug target genes, such as PIK3CA(25), PTEN(3), AKT1(3), ALK(3), ROS1(2), FGFR4(3), FGFR3(2), ERBB2(2), and IDH1(1) etc. In a pathway analysis, mutations in insulin signaling pathway were most dominant. We hypothesized that driver gene and therapeutic target has to have recurrent mutation and gene expression at least more than average expression. We calculated expression “Volume” according to the median normalized FPKM value of individual gene's RNA-seq data. With a cut-off of 3 or more mutations in each gene, 1,116 genes were selected. After the filtering of Volume<0.3, 696 genes were selected. Finally, 55 genes were selected which are druggable or potentially druggable using drug database (DrugBank, TOCRIS, Ingenuity) and Pubmed. DriverNet analysis result was also considered for the selection. All 342 tumor suppressor genes were filtered out. Interestingly, 18 of the 55 were genes involved in metabolism (fatty acid, glucose, amino acids). 12 were kinases and 4 were involved in insulin pathway. Excluding the previously confirmed therapeutic target, PIK3CA, AKT1, and NOTCHs, and considering the patients’ clinical data, our primary candidates for hormone-resistant breast cancer were NQO2, CELSR1, GLUD2, MYH9, PSMD2, NADK, IRS2, MAP3K5, and for triple-negative breast cancer were HSPG2, PHGDH, MYLK, etc. Validation with Sanger sequencing and functional study is on-going.

Abstract
Objectives Patients with cervical cancer have lower bone mass than women without cancer, whereas women with endometrial cancer have higher bone mineral density (BMD) than control subjects, possibly due to the prevalence of high body-fat mass. The aim of this study was to compare BMD in patients with cervical cancer, endometrial cancer and controls. Methods We analyzed and compared spinal and femoral BMD in 130 patients with cervical cancer, 68 with endometrial cancer, and 140 age-matched menopausal female control subjects. We also compared serum calcium, phosphorus, total alkaline phosphatase, osteocalcin, and urinary deoxypyridinoline levels. Results Compared with the control group, T-scores for some lumbar vertebrae (L4), the femoral neck, and Ward's triangle were lower in patients with cervical cancer, whereas only L4 T-scores were significantly lower in patients with endometrial cancer. Deoxypyridinoline levels were significantly lower in women with endometrial cancer (p < 0.002) than in women with cervical cancer, but no other biochemical variables differed among groups. Conclusions Cervical cancer was associated with lower BMD, especially in femoral BMD, and may be a risk factor for secondary osteoporosis. However, endometrial cancer generally seemed to have no damaging effect on bone except at L4. A further larger follow-up study in more populations is required to clarify these findings.

Abstract
PURPOSE The purpose of this study was to determine whether chemoradiation (CCR) is efficient for improving prognosis, compared with systemic chemotherapy (SC), in patients with stage IVB cervical cancer who have distant lymphatic metastasis. MATERIALS AND METHODS Among 2,322 patients with cervical cancer between January 2000 and March 2010, 43 patients (1.9%) had stage IVB disease. After exclusion of 19 patients due to insufficient data and hematogenous metastasis, 24 patients (1%) who received CCR (n=10) or SC (n=14) were enrolled. We compared tumor response, progression-free survival (PFS) and overall survival (OS), and disease recurrence between CCR and SC. RESULTS Complete response rates were 60% and 0% after CCR and SC (p<0.01). Grade 3 or 4 leukopenia was more common in patients treated with CCR (24.4% vs. 9.1%, p=0.03), whereas grade 3 or 4 neuropenia was more frequent in those treated with SC (28.4% vs. 11.1%, p=0.03). Development of grade 3 proctitis occurred as a late radiotherapy (RT)-related toxicity in only one patient (10%) treated with CCR. In addition, squamous cell carcinoma and CCR were favorable prognostic factors for improvement of PFS (adjusted hazard ratios [HRs], 0.17 and 0.12; 95% confidence intervals [CIs], 0.04 to 0.80 and 0.03 to 0.61), and only CCR was significant for improvement of OS (adjusted HR, 0.15; 95% CI, 0.02 to 0.90). However, no differences in the rate and pattern of disease recurrence were observed between CCR and SC. CONCLUSION CCR may be more effective than SC for improving survival, and can be regarded as a feasible method with some caution regarding late RT-related toxicity for treatment of stage IVB cervical cancer with distant lymphatic metastasis.

Abstract
OBJECTIVE We investigated whether the level of vascular endothelial growth factor (VEGF) and inflammatory markers in mid-trimester amniotic fluid have predictive value for spontaneous preterm birth in singleton pregnancy. METHOD Our subjects were 72 pregnant women who were undertaken with amniocentesis from 16 to 19 weeks of gestation. 36 cases were women with preterm delivery, and other 36 cases were matched women with full-term delivery. Stored amniotic fluid was investigated after the delivery. The levels of matrix metalloproteinases-8 (MMP-8), interleukin-6 (IL-6), C-reactive protein (CRP), and VEGF were measured by enzyme-linked immunosorbent assay (ELISA) and Western blot. RESULTS The levels of MMP-8 and IL-6 in preterm group were significantly higher than control group (5.76 ± 1.53 ng/ml vs 4.89 ± 1.77 ng/ml and 170.54 ± 55.69 pg/ml vs 141.92 ± 57.21 pg/ml, respectively) (p < 0.05). In terms of VEGF, the levels were elevated in preterm group (30.76 ± 4.06 pg/ml vs 22.36 ± 7.03 pg/ml) (p < 0.05). CONCLUSION This study suggests that elevated levels of IL-6 and MMP-8 in amniotic fluid at mid-trimester are predictive of preterm delivery, and that VEGF which is representative of angiogenesis can be a new and useful predictor of preterm delivery.

Abstract
The effects of quality grade (which reflects relative marbling) on the chemical, physical and sensory properties was investigated using Korean native cattle (Hanwoo) beef. Thirty-six Hanwoo cows were slaughtered and the carcasses were graded at 24h postmortem according to the Korean carcass grading system. The quality grade 1 (high quality), grade 2 and grade 3 (low quality) were based on the marbling score of longissimus dorsi (LD) muscles. The effects of quality grade on the meat quality parameters of beef LD muscle were assessed during aging. Loin-eye area, fat thickness and yield grade were all similar for the three quality groups. Mean lean color, fat color and maturity scores did not differ among quality grade groups (P>0.05). pH, Sarcomere length, WHC, collagen content, cooking loss, shear force and MFI were not affected by quality grade groups. Drip loss for grade 1 group was significantly lower than that for grade 3 groups (P<0.05). At initial tenderness evaluation of steaks, no differences among the three grades were observed; however, with additional days of storage, grade 1 steaks had higher tenderness score than grade 3 steaks (P<0.05). Increased postmortem aging time improved tenderness attributes regardless of quality groups. No significant differences were found among the quality grade groups for flavor (P>0.05). The grade 1 group had the highest juiciness score, and grade 3 groups had the lowest score (P<0.05), but postmortem aging did not influence flavor and juiciness. The quality grades were more strongly related to juiciness than tenderness or flavor.

Abstract
BACKGROUND Colchicine, a first-line drug for the treatment of Behçet disease (BD), inhibits caspase-1 activation and inflammatory cytokine production. However, therapeutic and preventive effects are not observed in some patients with BD. OBJECTIVE To explore whether the effects of colchicine on proinflammatory cytokine expression and cell death in peripheral blood mononuclear cells (PBMCs) from patients with BD are associated with responsiveness to colchicine. METHODS Activation of caspase-1, transcription and secretion of interleukin (IL)-1β, tumour necrosis factor (TNF)-α and IL-6, and release of lactate dehydrogenase (LDH) in PBMCs isolated from healthy controls and patients with BD were analysed in the presence or absence of colchicine and upon stimulation with lipopolysaccharide (LPS) plus a caspase-1 activator. RESULTS Colchicine significantly modulated monosodium urate-induced IL-1β release, LPS-stimulated LDH release, and basal transcript levels of TNF-α and IL-6 in healthy controls and BD colchicine responders, but not in BD colchicine nonresponders. Notably, colchicine showed contrasting effects on LPS-stimulated IL-1β transcription, i.e. it increased in responders but decreased in nonresponders. Also, higher levels of TNF-α and IL-6 transcripts were observed in LPS-stimulated PBMCs from nonresponders compared with responders. CONCLUSIONS This study shows different effects of colchicine on PBMCs from patients with BD according to their responsiveness to colchicine. Predicting responsiveness to colchicine in patients with BD may, therefore, be possible by examining alterations in IL-1β transcript levels in LPS-stimulated PBMCs after colchicine treatment.
