Abstract
Background
Atherosclerosis is the main cause underlying cardiovascular disease (CVD). Docosahexaenoic acid (DHA, 22:6n-3) is a hydrophobic polyunsaturated fatty acid that exerts anti-inflammatory and antioxidant activities. However, the beneficial effects of DHA on CVD have been controversial likely due to variations in bioavailability after oral intake.
Purpose
In this study, we aim to investigate the potential inhibiting properties of liposomal DHA on atherosclerosis progression upon intravenous administration.
Methods
Four weeks old ApoE−/− and LDLr−/− mice were fed on athero-inducing high fat diet for 4 weeks and then randomly divided into two groups. The mice received either control liposomes (control group) or liposomes containing DHA (liposomal DHA treatment group) via intravenous injection, twice a week for 8 weeks while still being fed on high fat diet. At the experiment endpoint, whole aortas were collected for Oil Red O staining to quantify plaque area or for biochemical analysis. Plasma was collected for total cholesterol measurement and lipidomic analysis. Aortic roots were used for histological analysis.
Results
Upon intravenous injection, as shown by IVIS imaging, DHA-containing liposomes accumulated preferentially in the atherosclerotic plaques. Compared to control liposomes, liposomal DHA treatment reduced the atherosclerotic plaque area in both atherosclerosis animal models, with the total plaque area decreased by 35.8% in ApoE−/− mice, (p<0.001) and by 22.4% in LDLr−/− mice (p<0.05). Plaque composition analysis revealed that liposomal DHA treatment increased collagen content and reduced the number of macrophages and neutral lipid within the plaques, resulting in a lower plaque vulnerability index (1.095 for liposomal DHA treated group vs. 1.692 for control group, p<0.05). Among those plaque macrophages, as demonstrated by immunohistology, M2 (anti-inflammatory) macrophages accounted for 4.44% in liposomal DHA treated mice and 2.24% in control liposomes treated mice (p<0.05). In agreement with the histology results, higher mRNA expression levels of anti-inflammatory markers (IL-10, CD206 and CD163) and collagen type 1 were determined in aortic tissue after liposomal DHA treatment. Moreover, liposomal DHA did not change total cholesterol level in the blood but significantly lowered plasma levels of several species of triglycerides. In vitro experiment with bone marrow derived macrophages showed that liposomal DHA was able to suppress lipopolysaccharide-induced inflammatory response and oxidative stress.
Conclusions
Our findings demonstrate that incorporation of DHA in injectable liposomes is an effective way to increase the inhibitory effects of DHA on halting the progression of atherosclerosis via lowering circulating triglycerides, reducing plaque inflammation, and enhancing plaque stability. Intravenous administration of liposomal DHA may become an efficacious strategy for the treatment of atherosclerosis.

Abstract
Abstract
Background/Introduction
T wave inversion (TWI) is a potentially abnormal finding on pre-participation screening electrocardiography (ECG), as it may suggest an underlying cardiomyopathy that should be risk stratified appropriately to minimise the risk of sports-related sudden cardiac death. Existing international guidelines prescribe criteria for investigating TWI in athletes. However, it is not established if these criteria can be extrapolated to screening unselected individuals. There is also evidence recommending against investigating specific patterns of anterior TWI in certain subsets of athletes due to low diagnostic yield; whether these exemptions may apply to non-athletes is uncertain. Given the importance of physical activity for primary prevention of cardiovascular disease in the general population, more evidence to guide pre-participation ECG screening of unselected individuals is needed.
Purpose
Firstly, to determine the epidemiology of abnormal TWI in a large unselected pre-participation cohort of young males of predominantly Asian ethnicity. Secondly, to determine the diagnostic yield of an echocardiography-guided approach to investigating individuals with abnormal TWI for a cardiomyopathy.
Methods
All individuals who attended a national centre for pre-enlistment cardiac screening over 39 months from 2017 were examined. Demographic data, anthropometric data and standardised physical fitness test scores were collected. Resting 12-lead ECG was performed for all individuals. Those with abnormal TWI, defined as a negatively deflected T wave of at least 0.1 mV amplitude in two contiguous leads, were referred to tertiary centres for echocardiography.
Results
69,714 consecutive males of mean age 17.9±1.1 years were screened. 562 individuals (0.8%) displayed abnormal TWI. Better aerobic fitness, but not muscular strength, was associated with a higher prevalence of abnormal TWI in general and specifically in the anterior territory, although not beyond leads V1-V2. Aerobic fitness had no association with abnormal TWI in the inferior territory or lateral territory. Of those with abnormal TWI, 12 individuals (2.1%) were newly diagnosed with a cardiomyopathy. Significant factors associated with a cardiomyopathy diagnosis were abnormal TWI in the lateral territory, abnormal TWI in the anterior territory beyond lead V2, deeper maximum TWI depth, presence of hypertension and higher body mass index. No individual presenting with TWI restricted to solely leads V1-V2 and/or two inferior leads without abnormal TWI in other contiguous leads was diagnosed with a cardiomyopathy.
Conclusion
Investigating abnormal TWI in an unselected pre-participation cohort of young Asian males had a significant yield, particularly in individuals manifesting abnormal TWI in the lateral territory and the anterior territory beyond lead V2. The ECG finding of anterior TWI in an unselected population may not be as benign as that in athletic populations.

Abstract
Abstract
Introduction
Home blood pressure monitoring (HBPM) is a useful tool to identify hypertension and to decide whether a patient's blood pressure (BP) is controlled. The use of automatized oscillometric BP measurement devices has become increasingly popular with help of information technology and internet of things to the devices. However, applying HBPM to daily clinical practices is still challenging, because most patients with hypertension are in age groups not familiar to digital devices and internet and high BP criteria using average home BP values are often useless in outpatient clinics without easily accessible average BP calculation tools. Therefore, we developed a simple and straightforward method to interpret HBPM through counts of BP ≥135/85 mmHg.
Methods
We simulated 400 cases of HBPM using a random number generator function in statistical software. The simulated average home systolic BP (SBP) and its standard deviation (SD) were 125±15 mmHg and 12±5 mmHg and the number of HBP readings was 24 times. The simulated diastolic BP (DBP) was randomly selected to 50–75% of the SBP. The validation of the binary interpretation method was conducted using actual HBPM data from 386 subjects in a rural area of South Korea. Receiver operating characteristics curve analysis was conducted, and linear regression and logarithmic models were fitted between the numbers of home BP ≥135/85 mmHg and mean BP. Hypertension was defined with average home BP ≥135/85 mmHg.
Results
In the simulated cohort, hypertension was presented in 197 cases (49.3%). The C-index of the numbers of BP readings ≥135/85 mmHg was 0.994 (95% confidence interval [CI] 0.990–0.998), and ≥12 of 24 BP readings ≥135/85 mmHg showed a sensitivity of 95.4%, a specificity of 95.1% and an accuracy of 95.3% for the diagnosis of hypertension. In validation cohort, the numbers of home BP measurements varied from 8 to 81 times. The validation cohort similarly showed that the C-index of the ratio between the number of high BP readings (≥135/85 mmHg) to the number of BP measurements (R-NHBP/NBP) was 0.985 (95% CI, 0.976–0.994) and the best accuracy was shown at R-NHBP/NBP of ≥0.45. R-NHBP/NBP of ≥0.5 showed a sensitivity of 0.957, a specificity of 0.907 and an accuracy of 0.927. The accuracy of the R-NHBP/NBP of ≥0.5 decreased as SD and the range of SBP increased, whereas it did not change with the number of measurements (Figure 1). R-NHBP/NBP <0.2 predicted normotension and R-NHBP/NBP >0.8 predicted hypertension in 95% confidence. Mean widths of the 95 prediction intervals for the average SBP and DBP were 18.2 mmHg and 12.6 mmHg, respectively (Figure 2).
Conclusion
Counting the number of BP ≥135/85 mmHg can provide accurate assessments for the BP levels. R-NHBP/NBP of ≥0.5 is a simple and accurate marker of high BP in HBPM, and R-NHBP/NBP could be a useful tool to assess BP levels in patients practicing HBPM.

Abstract
BACKGROUND Adjuvant chemotherapy and chemoradiotherapy are some of the standards of care for gastric cancer (GC). The Adjuvant chemoRadioTherapy In Stomach Tumors (ARTIST) 2 trial compares two adjuvant chemotherapy regimens and chemoradiotherapy in patients with D2-resected, stage II or III, node-positive GC. PATIENTS AND METHODS The ARTIST 2 compared, in a 1:1:1 ratio, three adjuvant regimens: oral S-1 (40-60 mg twice daily 4 weeks on/2 weeks off) for 1 year, S-1 (2 weeks on/1 week off) plus oxaliplatin 130 mg/m2 every 3 weeks (SOX) for 6 months, and SOX plus chemoradiotherapy 45 Gy (SOXRT). Randomization was stratified according to surgery type (total or subtotal gastrectomy), pathologic stage (II or III), and Lauren histologic classification (diffuse or intestinal/mixed). The primary endpoint was disease-free survival (DFS) at 3 years; a reduction of 33% in the hazard ratio (HR) for DFS with SOX or SOXRT, when compared with S-1, was considered clinically meaningful. The trial is registered at clinicaltrials.gov (NCT0176146). RESULTS A total of 546 patients were recruited between February 2013 and January 2018 with 182, 181, and 183 patients in the S-1, SOX, and SOXRT arms, respectively. Median follow-up period was 47 months, with 178 DFS events observed. Estimated 3-year DFS rates were 64.8%, 74.3%, and 72.8% in the S-1, SOX, and SOXRT arms, respectively. HR for DFS in the control arm (S-1) was shorter than that in the SOX and SOXRT arms: S-1 versus SOX, 0.692 (P = 0.042) and S-1 versus SOXRT, 0.724 (P = 0.074). No difference in DFS was found between SOX and SOXRT (HR 0.971; P = 0.879). Adverse events were as anticipated in each arm, and were generally well-tolerated and manageable. CONCLUSIONS In patients with curatively D2-resected, stage II/III, node-positive GC, adjuvant SOX or SOXRT was effective in prolonging DFS, when compared with S-1 monotherapy. The addition of radiotherapy to SOX did not significantly reduce the rate of recurrence after D2 gastrectomy.

Abstract
Background To identify predictive markers for responders in lapatinib-treated patients and to demonstrate molecular changes during lapatinib treatment via cell-free genomics. Patients and methods We prospectively evaluated the efficacy of combining lapatinib with capecitabine and oxaliplatin as first line neoadjuvant therapy in patients with previously untreated, HER2-overexpressing advanced gastric cancer. A parallel biomarker study was conducted by simultaneously performing immunohistochemistry and next-generation sequencing (NGS) with tumor and blood samples. Results Complete response was confirmed in 7/32 patients (21.8%), 2 of whom received radical surgery with pathologic-confirmed complete response. Fifteen partial responses (46.8%) were observed, resulting in a 68.6% overall response rate. NGS of the 16 tumor specimens demonstrated that the most common co-occurring copy number alteration was CCNE1 amplification, which was present in 40% of HER2+ tumors. The relationship between CCNE1 amplification and lack of response to HER2-targeted therapy trended toward statistical significance (66.7% of non-responders versus 22.2% of responders harbored CCNE1 amplification; P = 0.08). Patients with high level ERBB2 amplification by NGS were more likely to respond to therapy, compared with patients with low level ERBB2 amplification (P = 0.02). Analysis of cfDNA showed that detectable ERBB2 copy number amplification in plasma was predictive to the response (100%, response rate) and changes in plasma-detected genomic alterations were associated with lapatinib sensitivity and/or resistance. The follow-up cfDNA genomics at disease progression demonstrated that there are emergences of other genomic aberrations such as MYC, EGFR, FGFR2 and MET amplifications. Conclusions The present study showed that HER2+ GC patients respond differently according to concomitant genomic aberrations beyond ERBB2, high ERBB2 amplification by NGS or cfDNA can be a positive predictor for patient selection, and tumor genomic alterations change significantly during targeted agent therapy.

Abstract
Background Arginine depletion is a putative target in hepatocellular carcinoma (HCC). HCC often lacks argininosuccinate synthetase, a citrulline to arginine-repleting enzyme. ADI-PEG 20 is a cloned arginine degrading enzyme-arginine deiminase-conjugated with polyethylene glycol. The goal of this study was to evaluate this agent as a potential novel therapeutic for HCC after first line systemic therapy. Methods and patients Patients with histologically proven advanced HCC and Child-Pugh up to B7 with prior systemic therapy, were randomized 2 : 1 to ADI-PEG 20 18 mg/m2 versus placebo intramuscular injection weekly. The primary end point was overall survival (OS), with 93% power to detect a 4-5.6 months increase in median OS (one-sided α = 0.025). Secondary end points included progression-free survival, safety, and arginine correlatives. Results A total of 635 patients were enrolled: median age 61, 82% male, 60% Asian, 52% hepatitis B, 26% hepatitis C, 76% stage IV, 91% Child-Pugh A, 70% progressed on sorafenib and 16% were intolerant. Median OS was 7.8 months for ADI-PEG 20 versus 7.4 for placebo (P = 0.88, HR = 1.02) and median progression-free survival 2.6 months versus 2.6 (P = 0.07, HR = 1.17). Grade 3 fatigue and decreased appetite occurred in <5% of patients. Two patients on ADI-PEG 20 had ≥grade 3 anaphylactic reaction. Death rate within 30 days of end of treatment was 15.2% on ADI-PEG 20 versus 10.4% on placebo, none related to therapy. Post hoc analyses of arginine assessment at 4, 8, 12 and 16 weeks, demonstrated a trend of improved OS for those with more prolonged arginine depletion. Conclusion ADI-PEG 20 monotherapy did not demonstrate an OS benefit in second line setting for HCC. It was well tolerated. Strategies to enhance prolonged arginine depletion and synergize the effect of ADI-PEG 20 are underway. Clinical Trial number www.clinicaltrials.gov (NCT 01287585).

Abstract
BACKGROUND Capecitabine plus oxaliplatin (XELOX) has shown modest activity and tolerable toxicity in a phase II trial for biliary tract cancers (BTCs). Meanwhile, gemcitabine plus oxaliplatin (GEMOX) has been the reference arm in recent phase II and III trials for BTCs. We aimed to investigate the efficacy of XELOX versus GEMOX as first-line therapy for advanced BCTs. PATIENTS AND METHODS In this open-label, randomized, phase III, noninferiority trial, we randomly selected patients with metastatic BCTs to receive GEMOX (gemcitabine 1000 mg/m2 on days 1 and 8, and oxaliplatin 100 mg/m2 on day 1) or XELOX (capecitabine 1000 mg/m2, twice daily, on days 1-14 and oxaliplatin 130 mg/m2 on day 1) as first-line treatment, given every 3 weeks, totaling eight cycles. The primary end point was to prove the noninferiority of XELOX to GEMOX in terms of 6-month progression-free survival (PFS) rate. RESULTS In total, 114 patients randomly received GEMOX and 108 randomly received XELOX. The median PFS was 5.3 months for the GEMOX group and 5.8 months for the XELOX group. The 6-month PFS rate was 44.5% for the GEMOX group and 46.7% for the XELOX group. The 95% confidence interval of the 6-month PFS rate difference between both groups was -12% to 16%, meeting the criteria for noninferiority of XELOX to GEMOX. There was no difference in objective response (P=0.171) and median overall survival (P=0.131) between both groups. The most common grade three to four adverse events were neutropenia and thrombocytopenia. No patient died of treatment-related causes. The XELOX group had significantly lower frequencies of hospital visits than the GEMOX group (P<0.001). CONCLUSION XELOX showed significant noninferiority to GEMOX in terms of 6-month PFS rate. Thus, XELOX could be an alternative first-line treatment of BCTs. TRIAL REGISTRATION This study was registered in ClinicalTrials.gov (number NCT01470443).

Abstract
INTRODUCTION Flow cytometry is used in the diagnosis of haematological diseases including chronic lymphoproliferative disorders. This audit aims to ascertain the real-world indications for peripheral blood (PB) flow cytometry and which of these are associated with higher diagnostic yields. METHODS All PB flow cytometry requests for chronic lymphoproliferative disorders from 1 January 2014 to 31 December 2014 were identified using the laboratory information system. Data including patient demographics, specialty of requestor, lymphocyte count and blood film report (if available), indications for tests and subsequent diagnosis were collected. RESULTS A total of 185 requests with median patient age of 60 years were analysed. The main requestor was the Haematology Unit (n = 109; 58.9%) although the diagnostic yield of their requests was not significantly better than other units combined (16.5% vs 13.2%, P = .49). Factors that significantly improved the diagnostic yield of testing were older age, the presence of atypical lymphocytes on the blood film and lymphocytosis (P < .01). Constitutional symptoms and cytopenias were not found to influence the diagnostic yield. CONCLUSION PB flow cytometry is a useful tool when used in the appropriate clinical setting. Rationalisation of testing is important to reduce the futility of testing and unnecessary health costs.

Abstract
Streptococcus constellatus is an extremely rare cause of pyogenic spondylodiscitis. Literature search yielded only one case report in an elderly 72 years old man with spontaneous T10-T11 S. constellatus spondylodiscitis. It is virtually unheard of in young teenage. We report the case of a 14 years old male teenager who presented with worsening low back pain for one year with no neurological deficit. Imaging studies were consistent with features of L4-L5 spondylodiscitis. CT guided biopsy grew a pure culture of streptococcus constellatus sensitive to penicillin and erythromycin. He showed full recovery with six weeks of intravenous antibiotics. Due to the insidious onset, this case highlight the importance of high clinical suspicion and early diagnosis, with image guided biopsy followed by treatment with appropriate intravenous antibiotics to enable full recovery without further neurological deterioration.

Abstract
Background Targeting oncogenic genomic aberrations is an established therapeutic strategy in multiple tumor types. Molecular classification has uncovered a number of novel targets, and rapamycin-insensitive companion of mTOR (RICTOR) amplification has been identified in lung cancer. Further investigation assessing the therapeutic potential of RICTOR amplification as a novel target across advanced cancers is needed. Patients and methods Tumor samples from 640 patients with metastatic solid tumors, primarily gastrointestinal and lung cancers were prospectively subjected to a next-generation sequencing (NGS) assay to identify molecular targets. Samples with NGS-detected RICTOR amplification were confirmed with FISH. A RICTOR-amplified patient-derived cell (PDC) line was generated and used to investigate the effectiveness of selective AKT, mTORC1, and mTORC1/2 inhibition. Results NGS identified 13 (2%) of 640 patients with RICTOR-amplified tumors (6 gastric, 3 NSCLC, 1 SCLC, 1 CRC, 1 sarcoma, 1 MUO). Of the 13 patients, seven patients had RICTOR protein overexpression by IHC. The prevalence of RICTOR amplification in gastric cancer by NGS was 3.8% (6/160). FISH testing confirmed amplification (RICTOR/control >2) in 5/13 (38%) of samples, including four gastric cancers and one lung cancer. Treatment of a RICTOR amplified PDC with a selective AKT (AZD5363), selective mTORC1 (everolimus), dual mTORC1/2 (AZD2014), and the multi-target kinase inhibitor pazopanib demonstrated preferential sensitivity to the mTORC1/2 inhibitor (AZD2014). Knockdown of RICTOR reversed PDC sensitivity to AZD2014, validating the importance of RICTOR amplification to the PDC line. Conclusions RICTOR amplification is a rare but therapeutically relevant genomic alteration across solid tumors. Our results support further pre-clinical and clinical investigation with AZD2014 in RICTOR amplified gastric cancer and highlights the importance of genomic profiling.

Abstract
BACKGROUND: The MAP2K1 K57T mutation is known to be a potential mechanism of primary and secondary resistance to EGFR inhibitors in metastatic colorectal cancer (CRC) and has also been reported to promote resistance to BRAF and MEK inhibitors. It is important to overcome therapeutic resistance to EGFR inhibitors to improve the treatment outcomes of metastatic CRC. METHODS: We established patient-derived tumor cells (PDCs) from metastatic lesions that newly appeared during treatment with a BRAF inhibitor (LGX-818) plus an EGFR inhibitor (cetuximab) in a patient with BRAF-mutant CRC. To investigate therapeutic options to overcome acquired resistance due to MAP2K1 mutation in BRAF-mutant CRC, we performed cell viability assays using the PDCs. RESULTS: We tested whether the PDCs were resistant to an EGFR inhibitor (cetuximab) and a BRAF inhibitor (sorafenib) as these cells were established at the time of resistance to the EGFR plus BRAF inhibitors. Moreover, the anti-tumor effect of AZD6244 (MEK inhibitor) was evaluated because PDCs harbored a MAP2K1 mutation at the time of resistance to the EGFR plus BRAF inhibitors. MTT proliferation assays showed that monotherapy with cetuximab, sorafenib, or AZD6244 did not suppress cell viability. We next tested viability of the PDCs to combination treatment with cetuximab plus AZD6244 and sorafenib plus AZD6244. Proliferation of PDCs was significantly inhibited by sorafenib and AZD6244, but not by cetuximab plus AZD6244. Investigation of the combined effect of sorafenib and AZD6244 using the calculated combination index (CI) showed synergistic effects of sorafenib and AZD6244 in combination therapy applied to PDCs with the MAP2K1 K57T mutation. CONCLUSION: Our results suggest that combination treatment with BRAF and MEK inhibitors might be a novel treatment strategy for MAP2K1 K57T-mutant CRC. This finding will be helpful to guide treatment of patients with CRC that is resistant to EGFR inhibitors.

Abstract
Cerebral venous thrombosis (CVT) is a rare venous thrombotic event. We review our local experience in the management of CVT in comparison to other venous thromboembolism (VTE) with specific focus on risk factors for thrombotic recurrence. Retrospective evaluation of consecutive CVT presentations from January 2005 to June 2015, at two major tertiary hospitals in Northeast Melbourne, Australia. This population was compared to a separate audit of 1003 consecutive patients with DVT and PE. Fifty-two patients (30 female, 22 male) with a median age of 40 (18-83) years, presented with 53 episodes of CVT. Twenty-nine episodes (55 %) were associated with an underlying risk factor, with hormonal risk factors in females being most common. The median duration of anticoagulation was 6 months with 11 receiving life-long anticoagulation. Eighty-one percent had residual thrombosis on repeat imaging, which was not associated with recurrence at the same or distant site. Nine (17 %) had CVT-related haemorrhagic transformation with two resultant CVT-related deaths (RR 22.5; p = 0.04). All three VTE recurrences occured in males with unprovoked events (RR 18.2; p = 0.05) who were subsequently diagnosed with myeloproliferative neoplasm (MPN). Compared to the non-cancer VTE population, non-cancer CVT patients were younger, had similar rate of provoked events and VTE recurrence, although with significantly higher rate of MPN diagnosis (RR 9.30 (2.29-37.76); p = 0.002) CVT is a rare thrombotic disorder. All recurrences in this audit occurred in male patients with unprovoked events and subsequent diagnosis of MPN, suggesting further evaluation for MPN may be warranted in patients with unprovoked CVT.

Abstract
There is a paucity of evidence supporting the necessity or duration of Pneumocystis jirovecii and antiviral prophylaxis as well as revaccination following autologous stem cell transplant (ASCT). A survey aimed at evaluating these policies was distributed to 34 ASCT centres across Australasia. The 26 survey respondents demonstrated significant heterogeneity in their infection prophylaxis and revaccination strategy post-transplant despite the availability of consensual guidelines.

Abstract
Background: The purpose of this randomised phase III trial was to evaluate whether the addition of simvastatin, a synthetic 3-hydroxy-3methyglutaryl coenzyme A reductase inhibitor, to XELIRI/FOLFIRI chemotherapy regimens confers a clinical benefit to patients with previously treated metastatic colorectal cancer. Methods: We undertook a double-blind, placebo-controlled phase III trial of 269 patients previously treated for metastatic colorectal cancer and enrolled in 5 centres in South Korea. Patients were randomly assigned (1 : 1) to one of the following groups: FOLFIRI/XELIRI plus simvastatin (40 mg) or FOLFIRI/XELIRI plus placebo. The FOLFIRI regimen consisted of irinotecan at 180 mg m−2 as a 90-min infusion, leucovorin at 200 mg m−2 as a 2-h infusion, and a bolus injection of 5-FU 400 mg m−2 followed by a 46-h continuous infusion of 5-FU at 2400 mg m−2. The XELIRI regimen consisted of irinotecan at 250 mg m−2 as a 90-min infusion with capecitabine 1000 mg m−2 twice daily for 14 days. The primary end point was progression-free survival (PFS). Secondary end points included response rate, duration of response, overall survival (OS), time to progression, and toxicity. Results: Between April 2010 and July 2013, 269 patients were enrolled and assigned to treatment groups (134 simvastatin, 135 placebo). The median PFS was 5.9 months (95% CI, 4.5–7.3) in the XELIRI/FOLFIRI plus simvastatin group and 7.0 months (95% CI, 5.4–8.6) in the XELIRI/FOLFIRI plus placebo group (P=0.937). No significant difference was observed between the two groups with respect to OS (median, 15.9 months (simvastatin) vs 19.9 months (placebo), P=0.826). Grade ⩾3 nausea and anorexia were noted slightly more often in patients in the simvastatin arm compared with with the placebo arm (4.5% vs 0.7%, 3.0% vs 0%, respectively). Conclusions: The addition of 40 mg simvastatin to the XELIRI/FOLFIRI regimens did not improve PFS in patients with previously treated metastatic colorectal cancer nor did it increase toxicity.

Abstract
BACKGROUND The efficacy and safety of axitinib, a potent and selective vascular endothelial growth factor receptors 1-3 inhibitor, combined with best supportive care (BSC) was evaluated in a global, randomized, placebo-controlled phase II trial in patients with locally advanced or metastatic hepatocellular carcinoma (HCC). PATIENTS AND METHODS Patients with HCC and Child-Pugh Class A who progressed on or were intolerant to one prior antiangiogenic therapy were stratified by tumour invasion (presence/absence of extrahepatic spread and/or vascular invasion) and region (Asian/non-Asian) and randomized (2:1) to axitinib/BSC (starting dose 5 mg twice-daily) or placebo/BSC. The primary end point was overall survival (OS). RESULTS The estimated hazard ratio for OS was 0.907 [95% confidence interval (CI) 0.646-1.274; one-sided stratified P = 0.287] for axitinib/BSC (n = 134) versus placebo/BSC (n = 68), with the median (95% CI) of 12.7 (10.2-14.9) versus 9.7 (5.9-11.8) months, respectively. Results of prespecified subgroup analyses in Asian versus non-Asian patients or presence versus absence of tumour invasion were consistent with the overall population. Improvements favouring axitinib/BSC (P < 0.01) were observed in secondary efficacy end point analyses [progression-free survival (PFS), time to tumour progression (TTP), and clinical benefit rate (CBR)], and were retained among Asian patients in the prespecified subgroup analyses. Overall response rate did not differ significantly between treatments and patient-reported outcomes favoured placebo/BSC. Most common all-causality adverse events with axitinib/BSC were diarrhoea (54%), hypertension (54%), and decreased appetite (47%). Baseline serum analyses identified potential new prognostic (interleukin-6, E-selectin, interleukin-8, angiopoietin-2, migration inhibitory factor, and c-MET) or predictive (E-selectin and stromal-derived factor-1) factors for survival. CONCLUSIONS Axitinib/BSC did not improve OS over placebo/BSC in the overall population or in stratification subgroups. However, axitinib/BSC resulted in significantly longer PFS and TTP and higher CBR, with acceptable toxicity in patients with advanced HCC. TRIAL REGISTRATION ClinicalTrials.gov, NCT01210495.

Abstract
The CD44+/CD24– phenotype identifies cancer stem cell (CSC) properties in canine mammary carcinoma (MC); however, the histopathological features associated with this phenotype remain to be elucidated. Here, we determined whether the CD44+/CD24– phenotype was associated with hormonal receptor (HR; estrogen receptor [ER] and/or progesterone receptor [PR]) status and/or triple (ER, PR, and human epithelial growth factor receptor 2)–negative (TN) subtype; conventional histological evaluation was also performed. We found that, as single markers, both CD44+ and CD24+ were associated with less aggressive histological types, low grade, and a non-TN subtype; both markers were associated with HR positivity. On the other hand, a CD44+/CD24– phenotype was associated with higher grade of carcinoma. Therefore, our results suggest that immunohistochemical phenotyping for CD44/CD24 is useful for the evaluation of tumor behavior as well as CSC-like properties in canine MCs.

Abstract
BACKGROUND In the AXIS trial, axitinib prolonged progression-free survival (PFS) vs sorafenib in patients with advanced renal cell carcinoma (RCC) previously treated with sunitinib or cytokines. METHODS In post hoc analyses, patients were grouped by objective response to prior therapy (yes vs no), prior therapy duration (< vs ⩾median), and tumour burden (baseline sum of the longest diameter < vs ⩾median). PFS and overall survival (OS), and safety by type and duration of prior therapy were evaluated. RESULTS Response to prior therapy did not influence outcome with second-line axitinib or sorafenib. PFS was significantly longer in axitinib-treated patients who received longer prior cytokine treatment and sorafenib-treated patients with smaller tumour burden following sunitinib. Overall survival with the second-line therapy was longer in patients who received longer duration of prior therapy, although not significant in the sunitinib-to-axitinib sequence subgroup; OS was also longer in patients with smaller tumour burden, but not significant in the cytokine-to-axitinib sequence subgroup. Safety profiles differed modestly by type and duration of prior therapy. CONCLUSIONS AXIS data suggest that longer duration of the first-line therapy generally yields better outcome with the second-line therapy and that lack of response to first-line therapy does not preclude positive clinical outcomes with a second-line vascular endothelial growth factor-targeted agent in patients with advanced RCC.

Abstract
Canine mammary tumors (CMTs) are morphologically and biologically heterogeneous, prompting several attempts to classify such tumors on the basis of their histopathological characteristics. Recently, molecular-based analysis methods borrowed from human breast cancer research have also been applied to the classification of CMTs. In this study, canine mammary neoplasms ( n = 648) occurring in Korea from 2008 to 2011 were analyzed according to the histological classification and grading system proposed by Goldschmidt et al. Furthermore, randomly selected mammary carcinomas ( n = 159) were classified according to the molecular subtype using immunohistochemical characteristics. Canine mammary neoplasia accounted for 52.6% (648/1250) of the tumors in female dogs, and 51.7% (340/648) of these were malignant. All of the carcinoma-anaplastic subtypes were grade III tumors (5/5, 100%), while most of the carcinoma-tubular subtypes (15/18, 83.3%) and carcinoma arising in a complex adenoma/mixed-tumor subtype (115/135, 85.2%) were grade I tumors. Tumor cell invasion into lymphatic vessels was most common in the comedocarcinoma, carcinoma-anaplastic, and inflammatory carcinoma subtypes. The most frequently occurring molecular subtype (70/159, 44%) was luminal A. However, the basal-like subtype was the most malignant and was frequently associated with grade III tumors and lymphatic invasion. The carcinoma-solid subtypes were also often of the basal-like subtype. Reclassification of CMTs using the newly proposed histopathological classification system and molecular subtyping could aid in determining the prognosis and the most suitable anticancer treatment for each case.

Abstract
BACKGROUND PEP02 is a novel highly stable liposomal nanocarrier formulation of irinotecan. This randomized phase II study evaluated the efficacy and safety of single agent PEP02 compared with irinotecan or docetaxel in the second-line treatment of advanced oesophago-gastric (OG) cancer. PATIENTS AND METHODS Patients with locally advanced/metastatic disease who had failed one prior chemotherapy regimen were randomly assigned to PEP02 120 mg/m(2), irinotecan 300 mg/m(2) or docetaxel (Taxotere) 75 mg/m(2) every 3 weeks. The primary end point was objective response rate (ORR). Simon's two-stage design was used and the ORR of interest was 20% (α = 0.05, type II error β = 0.10, null hypothesis of ORR was 5%). RESULTS Forty-four patients per arm received treatment, and 124 were assessable for response. The ORR statistical threshold for the first stage was reached in all arms. In the intent-to-treat (ITT) population, ORRs were 13.6% (6/44), 6.8% (3/44) and 15.9% (7/44) in the PEP02, irinotecan and docetaxel arms, respectively. The median progression-free survival (PFS) and overall survival were similar between the trial arms. Commonest grade 3-4 adverse event reported was diarrhoea in the PEP02 and irinotecan groups (27.3% versus 18.2%). CONCLUSION The ORR associated with PEP02 was comparable with docetaxel and numerically greater than that of irinotecan. PEP02 warrants further evaluation in the advanced gastric cancer setting.

Abstract
Molecular-based classification of canine mammary carcinomas (CMCs) has been a recent research focus. In human breast cancer, triple-negative and basal-like phenotypes are distinct molecular subgroups that are known for their poor prognosis, but these tumours are not yet well defined in the dog. The aim of this study was to determine whether CMCs include triple-negative and basal-like phenotypes by immunohistochemical assessment of expression of the oestrogen receptor (OR), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) and four basal markers, cytokeratin (CK) 14, CK5/6, p63 and the epidermal growth factor receptor (EGFR). In this study of 241 CMCs, 45 triple-negative tumours (OR(-), PR(-) and HER2(-)) were identified and this phenotype was associated with an unfavourable prognosis. In these tumours, the expression of CK14, CK5/6 and EGFR was related to clinicopathological parameters, while the expression of p63 was not relevant. The majority of the triple-negative tumours were of the basal-like phenotype, given that 75.6% of them expressed more than two basal markers. However, three of the basal markers were not uniformly expressed; therefore, the proportion of the basal-like phenotype was altered on the basis of the selection of the markers. Although both triple-negative and basal-like phenotypes are distinct entities in CMC, further study is needed to differentiate one from the other.

Abstract
BACKGROUND Retrospective and molecular biologic data suggest that sunitinib may be effective in patients with non-clear cell renal cell carcinoma (nccRCC). PATIENTS AND METHODS Eligibility criteria included advanced nccRCC except for collecting duct carcinoma and sarcomatoid carcinoma without identifiable renal cell carcinoma subtypes. Patients were treated with 50 mg/day oral sunitinib for 4 weeks, followed by 2 weeks of rest. The primary end point was overall response rate (RR). RESULTS Thirty-one eligible patients were enrolled. Twenty-four patients (77%) had prior nephrectomy. By Memorial Sloan-Kettering Cancer Center criteria, 8 patients (26%) had poor risk and 14 (45%) had intermediate risk. Twenty-two patients had papillary renal cell carcinoma (RCC), and three had chromophobe RCC. Eleven patients had partial response with a RR of 36% (95% confidence interval (CI) 19% to 52%) and an additional 17 patients (55%) had stable disease. Median duration of response was 12.7 months (95% CI 6.3-19.1 months), and median progression-free survival was 6.4 months (95% CI 4.2-8.6 months). At a median follow-up duration of 18.7 months (95% CI 13.7-23.7 months), 13 patients (42%) had died, resulting in an estimated median survival of 25.6 months (95% CI 8.4-42.9 months). Toxicity profiles were commensurate with prior reports. CONCLUSIONS Sunitinib has promising activity in patients with nccRCC (NCT01219751).

Abstract
BACKGROUND Docetaxel is widely used as a chemotherapeutic agent for gastric cancer treatment. A combined regimen with sunitinib demonstrated a synergistic antitumour effect in a preclinical model. The aim of this study was to evaluate the efficacy and safety of this combination in patients with unresectable or metastatic advanced gastric cancer following failure of treatment with a fluoropyrimidine and platinum combination. METHODS This open-label, phase II, randomised trial enrolled patients with unresectable or metastatic gastric cancer. Patients were assigned to either a docetaxel monotherapy arm (D only arm: 60 mg m(-2), every 3 weeks) or a combination arm (DS arm: docetaxel+sunitinib 37.5 mg every day). The primary end point of the study was time to progression and the secondary end points were overall response rate, disease control rate, overall survival, and toxicity profile. A pharmacokinetic study was also performed. RESULTS A total of 107 patients were entered into the study. The TTP was not significantly prolonged in the DS arm when compared with the D only arm (DS vs D only arm: 3.9 months (95% confidence interval (CI) 2.9-4.9) vs 2.6 months (95% CI 1.8-3.5) (P=0.206). The hazard ratio for TTP was 0.77 (95% CI 0.52-1.16). However, the objective response rate was significantly higher in the DS arm (41.1% vs 14.3%, P=0.002). Patients in the DS arm experienced stomatitis, diarrhoea, and hand-foot syndrome more frequently. CONCLUSION The addition of sunitinib to docetaxel did not significantly prolong TTP, although it significantly increased response.

Abstract
This retrospective study used abdominal computed tomography (CT) scan images to determine the optimal safe oblique angle for fluoroscopy in fluoroscope-assisted coeliac plexus block (CPB). Abdominal CT scans from 131 patients were included in the study: 42 patients with cancer of the pancreas head, 45 with cancer of the pancreas body and tail and 44 with chronic pancreatitis. The oblique angle and entry distance from the midline were measured at the T12 and L1 levels, and the safe angle range that avoided puncture of the organs was also measured. The optimal angle varied between the T12 and L1 levels, and between the right and left sides at the T12 level. There was no difference in the oblique angle between the patient groups. The optimal oblique angle for fluoroscopy was determined to be 17° for right T12, 18° for left T12, and 19° for both left and right L1.

Abstract
LBA4032 Background: Currently, there is no standard regimen for palliative chemotherapy in metastatic, unresectable biliary tract cancer (BTC). A phase II trial of erlotinib monotherapy showed a promising anti-tumor activity in BTC with tolerable toxicity. Additionally, gemcitabine + erlotinib demonstrated superior efficacy when compared to gemcitabine alone in pancreatic cancer. Hence, we conducted a phase III trial to compare between GEMOX vs GEMOX+erlotinib (Tarceva [T]) (GEMOX/T) as first-line chemotherapy in unresectable, metastatic BTC. Methods: Eligible patients were as follows: histologically confirmed adenocarcinoma of biliary tract (CCC), ampulla of vater (AOV) or gall bladder (GB); unresectable or metastatic; ECOG performance status of 0~2; adequate marrow, hepatic, renal and cardiac functions; no prior chemotherapy. The primary endpoint was progression free survival (PFS). The study regimen was gemcitabine 1,000mg/m2, oxaliplatin 100mg/m2, erlotinib 100mg qd daily q 2 weeks. Results: From February 2009 to August 2010, 268 pts were randomized, 133 patients to GEMOX arm and 135 patients to GEMOX/T arm. Patient characteristics: median age 61 yrs (range 30-82); male (63.4%); CCC (n=180, 67.2%), GB (n=82, 30.6%), and AOV (n=6, 2.2%). With a median follow-up of 13.9 months (range, 6.7 – 25.0), median PFS was 5.8 months (95% CI, 4.6 - 7.0) in GEMOX/T arm and 4.2 months (95% CI, 2.7 - 5.7) in GEMOX arm (P=0.080). In subgroup analysis (CCC, n=180), however, median PFS was significantly longer in GEMOX/T arm (5.9 months) when compared with GEMOX arm (3.0 months, P=0.049). The overall response rate was significantly higher in the GEMOX/T arm when compared with GEMOX arm. There was no significant difference in overall survival between the two arms (GEMOX/T: 9.5 months, 95% CI, 7.6 – 11.4; GEMOX: 9.5 months, 95% CI, 7.5 – 11.5; P=0.611). The EGFR mutation testing results in correlation to responsiveness to erlotinib will be presented at the meeting. Conclusions: This phase III represents the first multicenter, randomized trial to compare GEMOX vs GEMOX/T in unresectable, metastatic BTC. Although PFS was not prolonged in GEMOX/T, there was a significant benefit in terms of PFS in GEMOX/T arm for CCC patients.

Abstract
Prostate cancer is a common cancer, especially among elderly men. It is sometimes not diagnosed until it has metastasised. Disseminated intravascular coagulopathy (DIC) can be the presenting manifestation of prostate cancer, and can present with bleeding (varying from isolated epistaxis to generalised haemorrhage), intravascular thrombosis, or both. A case of recurrent epistaxis from DIC due to metastatic prostate cancer occurring in an 84-year-old Caucasian man is presented, and the pathophysiology and management of DIC in association with androgen-sensitive prostate cancer are discussed.

Abstract
3546 Background: VEGFRs and PDGFRs play key roles in the proliferation of HCC and tumor angiogenesis. Sunitinib malate (SU) is an oral, multitargeted tyrosine kinase inhibitor of VEGFRs, PDGFRs, KIT, RET and FLT3. This study reports the results of the first European/Asian, open-label, single-agent SU phase II study in pts with unresectable HCC. Methods: Key eligibility criteria include histologically confirmed measurable HCC; ECOG PS =1; Child-Pugh (CP)-A/-B; adequate organ function; and no brain metastases, ascites, or prior liver transplant. Pts receive SU at 50 mg/d for 4 wks every 6 wks (4/2 schedule). The primary endpoint is ORR by RECIST. Other assessments include safety (NCI CTCAE v3.0), PK and antitumor activity (tumor density, volumetric measurement of percent tumor necrosis [VMTN] and intratumor blood perfusion on monthly CT scan). Results: 37 pts (median 61 yrs [range 34–82]; male 92%; PS 0:1, 50%:44%; CP-A/-B, 84%/14%; 40.5% with prior local treatments) received a median of 2 cycles (range 1–7+) of SU. Grade 3–4 toxicities included thrombocytopenia (43%), neutropenia (24%), CNS symptoms (24%), asthenia (22%) and hemorrhage (14%). Grade 1–2 skin toxicity was frequently reported. Dose reductions were required in 27% of pts. Four pts developed grade 5 events including ascites, edema, bleeding, drowsiness and hepatic encephalopathy. Decreased tumor density was observed in 68% of pts and activity assessed by VMTN showed minor (<50%) and major (=50%) post-treatment tumor necrosis in 25% and 46% of pts, respectively. One confirmed PR and 39% SD (best confirmed response) have been achieved. Post-treatment tumor blood perfusion parameters (blood volume and blood flow), decreased by an average of 39% (range: 13–72%). Preliminary PK data do not suggest any differences in drug exposure between risk groups (CP-A or CP-B). Conclusions: Evidence of =50% tumor necrosis in 46% of pts receiving SU suggests outstanding antitumor activity. However, change in tumor size (RECIST) may be inappropriate as a primary endpoint to evaluate SU in patients with HCC. Initial safety findings indicate that further evaluation of SU in this pt population with improved pt selection and dose schedule modification is warranted. [Table: see text]

Abstract
BACKGROUND The aim of the study was to identify reliable predictive biological markers for treatment outcome following neoadjuvant adriamycin/docetaxel (AT) chemotherapy in locally advanced breast cancer patients. MATERIALS AND METHODS This study was a phase II study on AT neoadjuvant chemotherapy in locally advanced breast cancer patients. Patients received 50 mg/m(2) of doxorubicin intravenously (IV) over 15 min followed by docetaxel 75 mg/m(2) infused over 1 h, repeated every 3 weeks for three cycles. Surgery was performed within 3-4 weeks following the last cycle of chemotherapy. We analyzed the pre-treatment and post-treatment expression levels of ER, PgR, HER-2, Ki-67 proliferation index, and p53 and examined the correlation between the markers and clinical parameters with treatment response, overall survival and relapse-free survival following neoadjuvant treatment. RESULTS From July 2001 to September 2004, 61 patients were enrolled. The meaningful parameters adversely influencing survival were post-treatment ER(-) status (P = 0.013) and post-treatment Ki-67 index above 1.0% (P = 0.013). At the multivariate level, the post-treatment Ki-67 proliferation index < or = 1.0 was the only meaningful prognostic factor for better survival (P = 0.033). Notably, tumors with Ki-67 index < or = 1.0 were more likely to express ER with statistical significance (P = 0.002). Tumors with ER(+) and Ki-67 index < or = 1.0 showed the highest survival rate, followed by ER(+) and Ki-67 index > 1.0%, ER(-) and Ki-67 < or = 1.0%, and ER(-) and Ki-67 > 1.0% with the worst survival (P = 0.033). CONCLUSION Collectively, post-treatment ER status and Ki-67 proliferation index were prognostic of overall survival following neoadjuvant AT chemotherapy.

Abstract
BACKGROUND This study was to devise a prognostic model for metastatic gastric cancer patients undergoing first-line chemotherapy. PATIENTS AND METHODS A retrospective analysis was carried out on 1455 gastric cancer patients, who received first-line chemotherapy from September 1994 to February 2005. RESULTS At multivariate level, poor prognostic factors were no previous gastrectomy [P = 0.003; relative risk (RR), 1.191; 95% confidence interval (CI) 1.061-1.338], albumin < 3.6 g/dl (P = or <0.001; RR, 1.245; 95% CI 1.106-1.402), alkaline phosphatase > 85 U/l (P = or <0.001; RR, 1.224; 95% CI 1.092-1.371), Eastern Cooperative Oncology Group performance status of two or more (P = or <0.001; RR, 1.690; 95% CI 1.458-1.959), the presence of bone metastases (P = 0.001; RR, 1.460; 95% CI 1.616-1.836), and the presence of ascites (P = or < 0.001; RR, 1.452; 95% CI 1.295-1.628). Of 1434 patients, 489 patients (34.1%) were categorized as low-risk group (zero to one factors), 889 patients (62.0%) as intermediate-risk group (two to four factors), and 56 patients (3.9%) as high-risk group (five to six factors). Median survival durations for low, intermediate, and high-risk groups were 12.5 months, 7.0 months, and 2.7 months, respectively. CONCLUSIONS This model should facilitate the individual patient risk stratification and thus, more appropriate therapies for each metastatic gastric cancer patient.

Abstract
Irinotecan and cisplatin demonstrated promising outcomes in extensive-stage small-cell lung cancer. According to the dosage and schedule of irinotecan, efficacy and toxicity profiles showed subtle differences. This study was designed to evaluate efficacy and toxicity of 3-week schedule of irinotecan/cisplatin in patients with previously untreated extensive-stage small-cell lung cancer. The primary objective was to evaluate response rate and secondary objectives were overall survival and progression-free survival. Patients with previously untreated extensive-stage small-cell lung cancer were enrolled. Irinotecan 65 mg m-2 was administered on days 1 and 8 and cisplatin 60 mg m-2 on day 1. Treatment was repeated every 3 weeks. Seven out of 54 patients (13.0%) had complete response, and partial response was observed in 33 (61.1%). The overall response rate was 74.1% (95% CI; 62.0-82.2%). Stable disease was observed in eight (14.8%) and no progressive disease was observed. After a median follow-up duration of 28.7 months, the median overall survival and progressive-free survival were 13.6 and 6.5 months, respectively. Major grade 3/4 toxicities were neutropenia (50.0%), anorexia (42.6%), diarrhoea (29.6%), fatigue (29.6%) and vomiting (13.0%). There was one treatment-related death owing to pneumonia. Three-week schedule of irinotecan/cisplatin showed effective antitumour activity and moderate toxicities in patients with previously untreated extensive-stage small-cell lung cancer.

Abstract
BACKGROUND This nonrandomized open label phase II study evaluated the efficacy and safety of FOLFOXIRI in metastatic or recurrent gastric cancer patients. PATIENTS AND METHODS Patients with histologically proven, metastatic gastric adenocarcinoma, aged 18-70 years, performance status zero to two, no prior chemotherapy, and with signed written informed consent were eligible. Treatment consisted of irinotecan 150 mg/m2 day 1, oxaliplatin 85 mg/m2 day 1, leucovorin 100 mg/m2 day 1, and 5-fluorouracil 2000 mg/m2 as a 48-h continuous infusion starting on day 1, which was repeated every 2 weeks. RESULTS From August 2004 to August 2005, 48 patients were prospectively enrolled. The median age was 54 years (24-69). In total, 386 cycles were administered with a median of nine cycles per patient (range 1-12 cycles) and 45 of 48 patients were assessable for treatment response. An independent review of tumor responses resulted in overall response rate of 66.7% (95% confidence interval=53.4% to 80.0%) by intent-to-treat analysis with one complete response and 31 partial responses. The median survival of all patients was 14.8 months and the median time to progression was 9.6 months. Most common grade 3/4 toxic effects were neutropenia (12% of all cycles) and emesis (8% of all cycles). Grade 2 peripheral neuropathy occurred in five patients. One (2%) patient had severe tumor bleeding and five (10%) patients experienced grade 3 diarrhea. CONCLUSIONS The modified FOLFOXIRI combination chemotherapy showed a very promising preliminary antitumor activity and was generally well tolerated as a first-line treatment of patients with metastatic gastric cancer.

Abstract
4072 Background: Present study describes the first phase II study of S-1 including pharmacokinetic and pharmacogenomic evaluation for extra-Japanese Asian population with advanced gastric cancer. Methods: Chemo-naive advanced gastric cancer with measurable disease was enrolled. Initial dose of S-1 was b.i.d. at 35, then 40 mg/m2 according to devised dosing method (range, 90–160 mg/day) for 28 days every 6 weeks. Pharmacokinetic study was performed after 28-day administration at cycle 1 and 3. Microarray based CGH was performed with genomic DNA from peripheral mononuclear cells to detect the toxicity-related genetic changes. Results: When first 31 patients were enrolled, protocol was amended to conduct the study by two steps for additional patients at 40 mg/m2 without dose escalation in initial 31 patients of 35 mg/m2, because these patients showed neither significant nor cumulative toxicity. Of 62 patients enrolled, median relative dose intensity was 0.99. Overall response rate was 19.3% (95% CI, 9.2–29.5). With 558-day follow-up duration, median TTP and OS were 126 and 264 days, respectively. One-year survival rate was 33.9%. Toxicity increased with dose escalation, but there was no grade 4 toxicity. The most common significant toxicity was anemia. Pharmacokinetics parameters were similar to those of Japanese population. In microarray-CGH, we selected 18 genes with different copy numbers of 13 amplified and 5 deleted genes in patients with anemia. Conclusions: Our phase II study showed the feasibility of S-1 in gastric cancer at the dose of 35 mg/m2, and we suggested that selected 18 genes might be candidate markers for predicting anemia with S-1 treatment. No significant financial relationships to disclose.

Abstract
9552 Backgrounds: A number of pediatric sarcomas occur in adults, including Ewing’s sarcoma (EWS)/primitive neuroectodermal tumor (PNET) and rhabdomyosarcoma (RMS). However, these are rare in adult patients (pts) and differ from typical adult sarcomas in that they are generally considered as systemic disease. There is debate as to whether adults do worse than pediatric pts with the same stage of disease. This study was performed to investigate whether various clinical parameters such as tumor size, primary site, age at diagnosis and response to chemotherapy predict the outcome. Methods: 74 consecutive cases of previously untreated pts over 18 years who were diagnosed with EWS/PNET, RMS, and desmoplastic small round cell tumor (SRCT) between 1995 and 2005, were identified from the database at the Samsung Medical Center. Among them, 64 pts were reviewed retrospectively and 10 pts who were lost to follow up were excluded. All pts were treated by a multimodality therapeutic approach, including surgery, chemotherapy, and radiotherapy, based on the ongoing protocols at the time of diagnosis. Results: The median age of the patients was 28 years (range, 18 - 74 years) and the majority (62.5%) of patients was male. There were 35 (54.6%) cases of EWS/PNET, 25 (39.1%) of RMS and 4 (6.3%) of desmoplastic SRCT. 29 pts (45.3%) had metastatic disease and 42 pts (65.6%) were Intergroup RMS Study (IRS) groups III/IV at diagnosis. Median overall survival was 41.5 months (95% CI, 16.1–66.9 months) and 5 years-survival rates was 38.7% (95% CI, 26.7–50.6%) in all pts. In univariate analysis, age (p=0.015), IRS group (p=0.0007) and tumor size (p=0.044) were correlated with better survival. However, multivariate analysis showed that independent variables for better survival were age (p=0.017) and IRS group (p=0.016). In subset analysis, significant statistical correlation between age and overall survival was observed in pts with IRS group I/II. Notably, pts younger than 30 years showed favorable outcome. Conclusions: In this study, age at diagnosis and IRS group reflecting tumor burden were important prognostic factors. Therefore, it is necessary that adult pts with pediatric sarcomas should be included in pediatric protocols, whenever feasible, to provide proper management for the rare disease. No significant financial relationships to disclose.

Abstract
Control of nausea and vomiting is very important in determining patient compliance with cisplatin chemotherapy. A multicentre, randomized, single-blind study was conducted to compare the tolerability and efficacy of ramosetron with those of granisetron over 24 h following cisplatin administration to cancer patients. In eight study centres, a total of 194 adult patients were randomly assigned to receive either intravenous ramosetron 0.3 mg or intravenous granisetron 3.0 mg. The anti-emetic effect of ramosetron determined from the no-vomiting rate lasted longer, but there was no significant difference in the number of acute vomiting episodes or the severity of nausea between the two groups. In the tolerability evaluation, there were no statistically significant differences between the two groups, except for a higher incidence of dull headache in the granisetron group. Ramosetron and granisetron appear to have equivalent efficacy and tolerability profiles, but the effects of ramosetron on the prevention of acute vomiting in patients undergoing cisplatin chemotherapy were longer lasting.

Abstract
Keratocytes express MHC class I molecules constitutively, and keratocytes stimulated with IFN-gamma express MHC class II molecules. Unstimulated keratocytes constitutively express B7-1 and ICAM-1, as well as low levels of CD40 and 4-1BBL. These findings indicate that keratocytes may deliver both antigen-specific and costimulatory signals to CD4(+) and CD8(+) T cells. To demonstrate that keratocytes expressing B7-1 provide a costimulatory signal to T cells, CD4(+) or CD8(+) mouse T cells were incubated with anti-CD3 mAb and irradiated keratocytes. Enhanced proliferation of both CD4(+) and CD8(+) T cells occurred, and could be inhibited by anti-B7-1 mAb, indicating T cell costimulatory activity by B7-1 on the keratocytes. To demonstrate that keratocytes can deliver an antigen-specific signal, CD4(+) and CD8(+) T cells from herpes-infected mice were incubated with HSV-1-infected, irradiated keratocytes. The resulting T cell proliferation and production of Th1 cytokines (IL-2, IFN-gamma) indicated T cell activation by antigens presented by the infected keratocytes. These results show that keratocytes in the corneal stroma of the mouse can function as antigen-presenting cells and, thus, may play a role in immune-mediated stromal inflammation such as herpetic stromal keratitis.
