Abstract
BACKGROUND Chemotherapy in combination with anti-epidermal growth factor receptor (EGFR) antibody is considered a first-line treatment regimen for RAS wild-type and left-sided metastatic colorectal cancer (mCRC), whereas second-line treatment regimens have not yet been established. Few studies have prospectively evaluated second-line treatment with anti-vascular endothelial growth factor antibody after first-line anti-EGFR antibody therapy for RAS wild-type mCRC. PATIENTS AND METHODS This non-randomized phase II trial investigated the clinical outcomes of second-line ramucirumab (RAM) plus fluorouracil, levofolinate, and irinotecan (FOLFIRI) after first-line anti-EGFR antibody in combination with doublet or triplet regimen in patients with RAS wild-type mCRC. The primary endpoint was the 6-month progression-free survival (PFS) rate. The secondary endpoints were PFS, overall survival (OS), objective response rate (ORR), rate of early tumor shrinkage (ETS), and safety. We hypothesized a threshold 6-month PFS rate of 30% and an expected 6-month PFS rate of 45%. Treatment was considered effective if the lower limit of the 90% confidence interval (CI) of the 6-month PFS rate was >0.30. RESULTS Ninety-two patients were enrolled in the study. The primary tumor was located on the left side in 86 (95.6%) patients. Twenty (22.0%) patients had received triplet plus cetuximab as previous therapy. Six-month PFS rate was 58.2% (90% CI 49.3% to 66.2%) with a median PFS of 7.0 months (95% CI 5.7-7.6 months). Median OS was 23.6 months (95% CI 16.5-26.3 months). The ORR and ETS rate were 10.7% and 16.9%, respectively, in 83 patients with measurable lesions. The 6-month PFS rate was comparable between patients previously treated with doublet and triplet regimens; however, median PFS was longer for the doublet regimen (7.4 versus 6.4 months, P = 0.036). CONCLUSIONS Our study demonstrated prospectively that RAM plus FOLFIRI is an effective second-line treatment after anti-EGFR antibody-containing first-line therapy in RAS wild-type and left-sided mCRC. Furthermore, the results were similar for patients who were previously treated with triplet regimen.

Abstract
Cancer-associated fibroblast (CAF), an activated type of fibroblast, is a major stromal cell that contributes to tumor initiation and development in the tumor microenvironment (TME). We previously reported that fractionated radiation rather than acute radiation causes progressive damage to mitochondria and increases the generation of reactive oxygen species, playing an important role in the fibroblast activation in normal tissue injury. Activated fibroblasts then become CAF by interacting with tumor cells, promoting tumor growth in vivo. We here examined the chronic radiation effect on fibroblast activation. Acute radiation (<2.5 Gy) did not increase alpha-Smooth muscle actin, a CAF marker expression in healthy human cells, whereas chronic radiation (2.5 Gy) did. It can be concluded that the induction of fibroblast activation changes across acute radiation, fractionated radiation, and chronic radiation depending on the irradiation technique. This study highlights that radiation activates fibroblasts, playing a role in radiation-related tumor development via TME formation.

Abstract
There are numerous global ocean wave reanalysis and hindcast products currently being distributed and used across different scientific fields. However, there is not a consistent dataset that can sample across all existing products based on a standardized framework. Here, we present and describe the first coordinated multi-product ensemble of present-day global wave fields available to date. This dataset, produced through the Coordinated Ocean Wave Climate Project (COWCLIP) phase 2, includes general and extreme statistics of significant wave height (Hs), mean wave period (Tm) and mean wave direction (θm) computed across 1980–2014, at different frequency resolutions (monthly, seasonally, and annually). This coordinated global ensemble has been derived from fourteen state-of-the-science global wave products obtained from different atmospheric reanalysis forcing and downscaling methods. This data set has been processed, under a specific framework for consistency and quality, following standard Data Reference Syntax, Directory Structures and Metadata specifications. This new comprehensive dataset provides support to future broad-scale analysis of historical wave climatology and variability as well as coastal risk and vulnerability assessments across offshore and coastal engineering applications.

Abstract
Abstract
Study question
Does the direction of formation for the first cleavage plane relative to the pronuclear axis affect clinical outcome?
Summary answer
A first cleavage division perpendicular to the pronuclear axis adversely affects the rate of embryo utilization for transfer or cryopreservation and the pregnancy outcome.
What is known already
It remains unclear how the first cleavage plane is determined in human embryos. By using time-lapse monitoring, our previous study (presented in ESHRE 2019) suggested that both the axis and locations of male and female pronuclei are involved in determining the first embryonic cleavage plane. Furthermore, by using immunofluorescence analysis, it was also revealed that most analyzed zygotes showed two pericentrin signals aligned around the interface between the male and female pronuclei. Our findings suggest that the pronuclear axis strongly influences the positions of the centrosomes, which become mitotic spindle poles and define the first cleavage plane. Study design, size, duration: From January 2015 to December 2017, time-lapse imaging (EmbryoScope®) of 3397 intracytoplasmic sperm injection (ICSI) oocytes was conducted. Of those, the relationship between the pronuclear axis and the first cleavage plane was analyzed in 607 normally fertilized embryos that cleaved to two cells and were obtained in 2015. Furthermore, of 3397 ICSI oocytes, 749 transferred embryos were classified based on the first cleavage patterns relative to the pronuclear axis, and the pregnancy rate was examined.
Participants/materials, setting, methods
A straight line connecting the centers of the pronuclei was defined as the 2PN axis. Based on the direction of the first cleavage relative to the 2PN axis, embryos were classified into three groups: parallel, perpendicular and intermediate. Fresh embryos were transferred on Day 2/3 (fresh-ET). Frozen and thawed embryos were transferred on Day 2/3 or Day 5 (F/T-ET). Clinical pregnancy was defined as confirmed gestational sac in the uterine cavity.
Main results and the role of chance
Of 607 analyzed embryos, 506 produced suitable images and were assigned to one of three groups: parallel (84.4%, n = 427), perpendicular (9.7%, n = 49) and intermediate (5.9%, n = 30). Embryos that formed a cleavage furrow parallel to the 2PN axis were significantly more frequent than others (perpendicular, intermediate) (P < 0.001). The embryo utilization rate for transfer or cryopreservation was significantly lower in the perpendicular group than in the parallel group (30.7% vs. 69.3%, P < 0.01). Furthermore, of 749 transferred embryos, 504 assigned to the parallel and perpendicular groups were selected (n = 470 and n = 34, respectively), and the pregnancy outcome was analyzed. The mean maternal age was not significantly different between groups. The pregnancy rate of embryos was 24.2% (n = 45/186) from fresh-ET and 39.4% (n = 112/284) from F/T-ET in the parallel group, and 0% (n = 0/14) from fresh-ET and 15.0% (n = 3/20) from F/T-ET in the perpendicular group. Regardless of the types of embryo transfer (fresh or F/T), the pregnancy rate was significantly lower in the perpendicular group than in the parallel group (P < 0.01). In addition, one of three patients who became pregnant from the transfer of an embryo in the perpendicular group had a miscarriage.
Limitations, reasons for caution
Since only ICSI embryos were analyzed in this study, the influence of fertilization methods on subsequent development could not be investigated. Further studies including preimplantation genetic testing for aneuploidy may help determine the reasons why pregnancy rates differ between groups.
Wider implications of the findings: We suggest that the 2PN axis is essential for determining the first cleavage plane because it seems to be involved in positioning the mitotic spindle poles. The direction of the first cleavage plane relative to the 2PN axis can be an important indicator for predicting embryo development and pregnancy outcome

Abstract
Abstract
Study question
Was embryonic development affected by the degree of perivitelline space (PS) at the pronuclear stage in human zygotes?
Summary answer
Zygotes with a fully surrounding PS showed less cytoplasmic fragmentation and a higher blastocyst development rate (BDR) than zygotes with a partially surrounding PS.
What is known already
We previously used abnormally-fertilized oocytes (zygotes with three pronuclei; 3PN), donated by ART patients in our clinic who gave written consent for the research. The zona pellucida (ZP) was artificially removed from these oocytes at the pronuclear stage, termed ZP-free culture. The resultant ZP-free 3PN embryos showed less cytoplasmic fragmentation and a higher rate of good-quality embryos (GQE) compared with ZP-intact embryos. Furthermore, in our clinical setting, the rate of GQE and BDR of normally-fertilized embryos were clearly improved by ZP-free culture in patients with recurrent failure of ART treatments due to severe cytoplasmic fragmentation at the early cleavage stage.
Study design, size, duration
This study included 49 patients who gave written informed consent for our study and were treated with ART in our clinic between March and December 2020. Embryonic development was compared between zygotes with a fully surrounding PS [PS(+)] with those with a partially surrounding PS [PS(-)] at the pronuclear stage. Furthermore, the ZP of PS(-) embryos were artificially removed at the pronuclear stage, and the rate of GQE and BDR were compared with ZP-intact embryos.
Participants/materials, setting, methods
The degree of PS in 128 zygotes was confirmed by hypertonic preparation using 0.125M sucrose-containing HEPES medium. PS(+) and PS(-) embryos were both cultured as ZP-intact, and the rate of GQE was compared. Furthermore, 223 zygotes were divided into three groups: 1) PS(-)/ZP-intact, 2) PS(-)/ZP-free, and 3) PS(+)/ZP-intact, and cultured in an incubator equipped with time-lapse monitoring up to Day 7, and the rate of GQE, BDR and useable embryos were compared between each groups.
Main results and the role of chance
The degree of PS was confirmed by a hypertonic preparation (shrinkage of the ooplasm) in 128 normally-fertilized zygotes obtained from 44 cases. There were 86 PS(-) (67.2%) and 42 PS(+) (32.8%) zygotes. The mean maternal age was 35.9 in PS(-) and 40.5 in PS(+) (P < 0.01), and the rate of GQE was significantly higher in PS(+) [64.3% (27/42)] than in PS(-)[38.4% (33/86)] (P < 0.01). In addition, of 223 normally-fertilized zygotes obtained from 41 cases, there were 51 PS(-)/ZP-intact (Group 1), 132 PS(-)/ZP-free (Group 2) and 40 PS(+)/ZP-intact (Group 3) zygotes. The rate of GQE was significantly lower in Group 1 [29.4% (15/51)] compared with Group 2 [59.8% (79/132)] and Group 3 [62.5% (25/40)] (P < 0.01). BDR was also significantly lower in Group 1 [51.3% (10/39)] compared with Group 2 [75.0% (99/132)] and Group 3 [65.0% (13/20) (P < 0.01).
Limitations, reasons for caution
Although the artificial removal of ZP at the pronuclear stage (ZP-free culture) clearly increased the rate of GQE, embryonic development was not improved in all cases. It seems that this procedure is only effective in embryos with a viable ooplasm.
Wider implications of the findings: The degree of PS at the pronuclear stage affects subsequent embryonic development in human zygotes. The artificial removal of ZP at the pronuclear stage (ZP-free culture) helps to suppress fragmentation and leads to an increase in GQE and BDR, and eventually, improves pregnancy rate in cases with severe fragmentation.

Abstract
Abstract
Study question
Is it possible to culture ZP-free embryos to eliminate perivitelline threads, which are known to be involved in generating cytoplasmic fragments at the first cleavage?
Summary answer
ZP-free culturing, an innovative system that decreases the amount of cytoplasmic fragments without disrupting the blastomeres, using incubators with time-lapse imaging.
What is known already
A study in 2017 observed perivitelline threads in more than 50% of cleavage-stage human embryos using time-lapse imaging, and the rate of cytoplasmic fragmentation (at the first cleavage) was significantly decreased in embryos without perivitelline threads (P < 0.001). While it has been proposed that perivitelline threads play an important role in crosslinking the cumulus cells and oocyte during maturation, the mechanism underlying such a role remains unclear. It is also unknown whether the threads still function in mature MII oocytes.
Study design, size, duration
A prospective study was conducted using 2,852 normal (2PN/2PB) embryos from c-IVF/ICSI and 113 abnormal (3PN) embryos obtained from c-IVF between 2017 and 2019. The zona pellucida (ZP) of 71 abnormal embryos was removed at the pronuclear stage (“ZP-free”), and the rest (n = 42) were cultured as “ZP-intact”. Normal and abnormal embryos were cultured for five days in bench-top incubators (MINC, COOK) and an incubator equipped with a time-lapse imaging system.
Participants/materials, setting, methods
Embryos used in this study were donated by 412 couples who underwent c-IVF cycles in our clinic between 2017 and 2019. For ZP removal, 3PN embryos were placed in 0.125M sucrose-containing HEPES media drops to reduce the ooplasm size. Then, ooplasms were completely separated from ZPs by a laser and pipetting. Embryo development and morphology of the three groups (normal, ZP-intact and ZP-free abnormal) were compared based on the degree of cytoplasmic fragmentation.
Main results and the role of chance
The first cleavage occurred in 97.8% (n = 2,790/2,852) of 2PN/2PB, 83.3% (n = 35/42) of ZP-intact 3PN and 97.2% (n = 69/71) of ZP-free 3PN. Normal (2PN/2PB), ZP-intact and ZP-free 3PN embryos were classified into three groups based on the modified Veeck’s criteria thus: <20% fragmented compared to the total volume of cytoplasm at the first cleavage (Grade 1 and 2, Good); 20–39% fragmented (Grade 3, Fair) and ≧40% fragmented (Grade 4, Poor). Of 69 cleaved ZP-free 3PN embryos, 68.1% (n = 47) showed less than 20% fragments which was significantly higher than 2PN/2PB (43.7%, n = 1,218/2,790) and ZP-intact 3PN (45.7%, n = 16/35; P < 0.05). Furthermore, 24.6% (n = 17/69) of ZP-free 3PN embryos showed 20–39% fragments which was significantly lower than 2PN/2PB (45.9%, n = 1,281/2,790; P < 0.05). In addition, 50.7% of ZP-free 3PN embryos (n = 36) developed to the morula stage after the third cleavage, and 29.6% (n = 21) formed blastocoel and became blastocysts. Thus, removing the ZP before the first cleavage did not adversely affect embryo development and decreased the cytoplasmic fragmentation.
Limitations, reasons for caution
Due to ethical and clinical limitations, we only examined abnormally fertilized embryos in this study. Moreover, since the relationship between the perivitelline threads and cytoplasmic fragments is unclear, we plan to conduct molecular biological analysis of the perivitelline threads in further studies.
Wider implications of the findings: This study revealed that ZP is not always necessary after the pronuclear stage because ZP-free embryos studied herein developed normally and maintained cell adhesion well. This innovative culture method might provide the breakthrough needed for patients to improve embryo quality who obtain embryos with severe fragmentation caused by perivitelline threads.

Abstract
Abstract
Study question
Why do some direct-cleaved human zygotes still lead to a live birth?
Summary answer
Direct-cleaved zygotes which have undergone the 2-cell stage can lead to a live birth, while zygotes cleaved from 1-cell to ≥ 3-cell do not.
What is known already
In recent years, zygotes that develop from 2-cell to 3-cell within 5 hours after the first cleavage have been evaluated as “direct-cleaved” zygotes, because normal cleavage takes approximately 12 hours to complete. It was reported that their implantation rate was significantly lower than zygotes with normal cleavage pattern, and eliminating direct-cleaved zygotes from transfer could improve the implantation rate. However, some direct-cleaved zygotes at the first cleavage could still lead to a live birth. Few reports have examined the difference between a cleavage from 1-cell to ≥ 3-cell and 2-cell to ≥ 3-cell within 5 hours after the first cleavage.
Study design, size, duration
A retrospective study involving 2,077 cycles of IVF/ICSI between July 2012 and July 2019. A total of 5,991 normally fertilized zygotes (2PN/2PB) were included. Of those, 3,508 were evaluated as usable good/fair quality embryos on Day2/3, and the rest (n = 2,483) were evaluated as poor quality and rejected from transfer or cryopreservation after 7 days of culture. Of 3,508 usable embryos, 884 were selected based on the availability of results of live birth for this study.
Participants/materials, setting, methods
Time-lapse imaging (5 slices along Z-axis every 10 minutes) was performed in EmbryoScopeTM. Zygotes were morphokinetically analyzed in detail and classified into four groups by their cleavage patterns: Group1 (1-cell→2-cell); Group 2 (1-cell→3-cell); Group 3 (1-cell→2-cell→≥3-cell within 5 hours after the first cleavage); and Group 4 (1-cell→2-cell→≥5-cell). The proportion, mean maternal age and live birth rate of each group were examined.
Main results and the role of chance
The proportion of Groups 1-4 was 83.6% (n = 739), 3.8% (n = 34), 5.9% (n = 52), and 6.7% (n = 59), respectively. 0f 884 zygotes examined in this study, the mean maternal age was significantly higher in Group 2 and 4 than in Group 1 (P < 0.05; 37.4±4.9 in Group1, 39.1±5.2 in Group 2, 38.6±6.0 in Group 3, and 38.7±5.1 in Group 4). The rate of confirmed gestational sac was significantly lower in Group 2 and 4 than in Group 1 [P < 0.01; 36.3% (n = 268/739), 0% (n = 0/34), 25.0% (n = 13/52), and 18.6% (n = 11/59) in Groups 1-4, respectively]. Furthermore, the live birth rate was significantly higher in Group 1 than in Groups 2, 3 and 4 [P < 0.01; 28.4% (n = 210/739), 0% (n = 0/34), 13.5% (n = 7/52), and 15.3% (n = 9/59) in Groups 1-4, respectively]. Above all, while zygotes in Group 2 showed no pregnancy and live birth at all, zygotes in Group 3 showed a live birth rate of 13.5%. However, they had a significantly higher miscarriage rate (42.9%, n = 6) compared to zygotes in Group 1 (19.5%, n = 55).
Limitations, reasons for caution
It is very difficult to capture cleavage patterns by routine observations because the timings of developmental events are different between embryos. A time-lapse imaging and culturing system is essential to solve this problem, however, it cannot visualize the distribution of chromosomes, and no chromosomal analysis was conducted in this study.
Wider implications of the findings
This study revealed that zygotes previously classified as “direct-cleaved” and eliminated from transfer included viable zygotes which could lead to a live birth. Therefore, it is crucial to optimize the use of time-lapse imaging of human zygotes in order to precisely evaluate the first cleavage.

Abstract
Study question
Can a novel embryo culture method that artificially removes the ZP at the pronuclear stage yield successful pregnancy in patients with poor-quality embryos and/or blastocysts?
Summary answer
A blastocyst transfer after ZP-free culture can result in pregnancy for patients who cannot obtain good quality blastocysts from conventional culture methods.
What is known already
Perivitelline threads are been associated with the formation of cytoplasmic fragments. We had previously observed perivitelline threads in the adhesive region between the ooplasm and the ZP at the first cleavage in human embryos. We removed the ZP at the pronuclear stage in 71 abnormally fertilized oocytes (zygotes with three pronuclei), donated after conventional IVF (c-IVF), and termed them ZP-free 3PN. We found ZP-free 3PN embryos could be cultured without losing blastomere adhesions. Furthermore, the rate of good quality embryos was significantly higher in ZP-free 3PN embryos compared with ZP-intact embryos (ZP-intact 2PN/2PB and 3PN embryos; P < 0.05).
Study design, size, duration
This study was conducted in two cases selected among patients who underwent ART treatment in our clinic between 2018 and 2019. Cases were selected if they lacked good quality blastocysts in previous c-IVF/Intracytoplasmic Sperm Injection (ICSI) cycles due to massive cytoplasmic fragmentation at the first and second cleavage. We performed a clinical trial of ZP-free culture from December 2019 to March 2020.
Participants/materials, setting, methods
Two cases were selected for this trial. Normally fertilized oocytes were grouped as ZP-free or ZP-intact. For the ZP-free group, 2PN embryos were placed in 0.125M sucrose-containing HEPES to reduce ooplasm size, then ooplasms were completely separated from ZPs by a laser and pipetting. ZP-free and ZP-intact embryos were cultured with time-lapse imaging for up to seven days. Resultant blastocysts were either transferred into uterus or cryopreserved on Day5/6/7 for future embryo transfer cycles.
Main results and the role of chance
The ZP-free culture method was applied to two patients (patient A and B) with recurrent failure of ART in our clinic due to poor-quality embryos and/or difficulties in obtaining good quality blastocysts. In both cases, blastocysts were successfully obtained and cryopreserved for all ZP-free culture cycles. In patient A, one good quality ZP-free blastocyst was freshly transferred five days after oocyte retrieval, and a live male baby (2925g) was delivered at 40 weeks of gestation by caesarean section). In patient B, a frozen/thawed ZP-free blastocyst transfer was conducted, and a live female baby (3225g) was delivered at 39 weeks of gestation by vaginal delivery. This shows ZP-free culturing may help obtain viable embryos in patients for which conventional in vitro culturing methods result in embryos characterized with severe cytoplasmic fragmentation and poor quality in the early cleavage stage.
Limitations, reasons for caution
Although successful pregnancies and deliveries were confirmed in two cases, postnatal evaluations will be absolutely necessary for infants derived from ZP-free culture. In addition, the number of trial cases needs to be expanded, however careful selection of suitable patients is necessary for this novel culture method.
Wider implications of the findings: We found removing the ZP at the pronuclear stage improved embryo development and led to successful pregnancies and deliveries after blastocyst transfer. This indicates ZP-free culturing may be an effective method for decreasing cytoplasmic fragmentation caused by perivitelline threads or adhesion between the ooplasm and the zona pellucida.

Abstract
Introduction
Recent trials demonstrated favorable effects of statins on the clinical prognosis, partly through anti-inflammatory properties, in patients with coronary artery disease. However, this favorable effect has not been fully verified in patients with peripheral arterial disease (PAD). We hypothesized that statins exert different prognostic effects depending on the degrees of inflammation at the time of endovascular therapy (EVT).
Methods
This study is a subanalysis from the Toma-Code Registry that is a Japanese prospective cohort of 2,321 consecutive patients with PAD treated by endovascular therapy in hospitals from 2014 to 2016. After the exclusion of patients without information of C-reactive protein (CRP) at the time of index EVT, 2,039 patients including 1,039 statin users and 1,000 statin non-users were ultimately analyzed. The patient enrolled were divided into 4 categories depending on CRP level at the time of EVT; Low-CRP (<0.1 mg/dL), Intermediate-low-CRP (0.1–0.3 mg/dL), Intermediate-High-CRP (0.3–1.0 mg/dL), and High-CRP (>1.0 mg/dL). A composite of death, stroke, myocardial infarction, and major amputation as the primary endpoint of this study was compared between statin users and non-users in each CRP category.
Results
The composite endpoint occurred in 255 patients during the observation period. Overall, statin users had a significantly lower event rate than non-users (Log-rank test: P<0.001). However, there were no significant difference in the event rates between statin users and non-users in the Low-, and Intermediate-Low-CRP categories. Only in the Intermediate-High- and the High-CRP categories, statin users showed a significantly lower event rates than non-users (P=0.02 and P=0.008, respectively, Figures). Additionally, multivariate Cox regression analysis in the High-CRP group revealed that statin use was independently associated with the primary endpoint (adjusted hazard ratio: 0.67 [95% confidence interval: 0.45–0.99]), even after the adjustment of covariants.
Conclusion
Statins may exert a favorable prognostic effect in PAD patients with highly elevated CRP, but not in those with low to moderate CRP level.

Abstract
Background
For recanalization of coronary chronic total occlusion (CTO) lesions, subintimal guidewire tracking in both antegrade and retrograde approaches are commonly used.
Purpose
This study aimed to assess the impact of subintimal tracking on long-term clinical outcomes after recanalization of CTO lesions.
Methods
Between January 2009 and December 2016, 474 CTO lesions (434patients) were successfully recanalized in our center. After guidewire crossing in a CTO lesion, those lesions were divided into intimal tracking group (84.6%, n=401) and subintimal tracking group (15.4%, n=73) according to intravascular ultrasound (IVUS) findings. Long-term clinical outcomes including death, target lesion revascularization (TLR), target vessel revascularization (TVR) were compared between the two groups. In addition, the rate of re-occlusion after successful revascularization was also evaluated.
Results
The median follow-up period was 4.7 years (interquartile range, 2.8–6.1). There was no significant difference of the rate of cardiac death between the two groups (intimal tracking vs. subintimal tracking: 7.0% vs. 4.1%; hazard ratio, 0.61; 95% confidence interval [CI], 0.19 to 2.00; p=0.41), TLR (14.3% vs. 16.2%; hazard ratio, 1.34; 95% CI, 0.71 to 2.53; p=0.37), and TVR (17.5% vs. 20.3%; hazard ratio, 1.27; 95% CI, 0.72 to 2.23; p=0.42). However, the rate of re-occlusion was significantly higher in the subintimal tracking group than intimal tracking group at 3-years re-occlusion (4.2% vs. 14.5%; log-rank test, p=0.002, Figure). In the multivariate COX regression, subintimal guidewire tracking was an independent predictor of re-occlusion after CTO recanalization (HR: 5.40; 95% CI: 2.11–13.80; p<0.001).

Conclusions
Subintimal guidewire tracking for recanalization of coronary CTO was associated with significantly higher incidence of target lesion re-occlusion during long-term follow-up period.

Abstract
e14204 Background: Although a causal relationship for inflammation and immunity of cancer is more widely accepted today, the precise cell mechanisms mediating this relationship have not been elucidated. Accumulating evidence suggests that myeloid-derived suppressor cells (MDSC), may contribute to the negative regulation of immune responses during cancer and inflammation. IL-17 is a pro-inflammatory cytokine that is primarily secreted by T helper (Th)17 cells and we have reported that IL-17 correlates with immunosuppressive conditions in patients with cancer. Methods: PBMC (peripheral blood mononuclear cells) were harvested from 106 patients including 43 with gastric and 63 with colorectal cancer. PBMC were stimulated with PHA (phytohemagglutinin) and the production of IL-17 was measured by ELISA. MDSC were detected by flow cytometry (CD11b+,CD14-,CD33+). The levels of CRP (C-reacting protein) and NLR (neutrophil to lymphocyte ratio) were used as inflammatory markers. Results: Both of MDSC and IL-17 production were increased in patients with advanced stages, and correlated with each other, inflammatory markers and immune suppression. The patients were divided with average levels of MDSC and IL-17 production and the prognosis were analyzed with Kaplan-Meier method. The overall survival of patients with high MDSC or high IL-17 production were significantly worse than those with low MDSC or low IL-17 production, respectively, in patients with stages III and IV, although the differences were not significant in patients with stages I and II. Conclusions: Thus these inflammatory markers are closely related with systemic inflammation involving IL-17 and with immunosuppression driven by MDSC, and are effective prognostic indicators in patients with stages III and IV gastric and colorectal cancer.

Abstract
The identification of novel biomarkers is of great importance for improving the outcome of patients with non-small cell lung cancer (NSCLC). Therefore, the aim of the present study was to determine whether the serum transthyretin (TTR) level could be used as a novel prognostic biomarker for patients with NSCLC. Serum TTR levels, and nutritional and inflammatory parameters were examined prior to treatment in 42 patients with NSCLC. Candidates for independent predictors of prognostic factors were subjected to univariate and multivariate analyses using a Cox proportional hazard model. IL-12-productivity, serum retinol binding protein, albumin and transferrin levels, and lymphocyte-to-monocyte ratio were significantly lower in the patients with TTR <22 mg/dl than those in the patients with TTR ≥22 mg/dl. Patients with serum TTR levels of <22 mg/dl exhibited a poorer overall (P=0.008) and recurrence-free survival (P=0.027) when compared with those with serum TTR levels of ≥22 mg/dl. The parameters, ≥T2 and age ≥75 years were independent prognostic factors for overall survival, and TTR <22 mg/dl and ≥T2 were independent prognostic factors for recurrence-free survival. In conclusion, anthropometric measurement of serum TTR, as well as T category, can be useful for predicting the 5-year recurrence-free survival of patients with NSCLC.

Abstract
Treatment containing FOLFIRINOX was planned to be administered to a 51-year-old man with locally advanced pancreatic cancer as second-line chemotherapy and to a 66-year-old woman with recurrent pancreatic cancer as third-line chemotherapy in their treatments. Since both patients were revealed to harbor UGT1A1 polymorphisms, which were highly associated with irinotecan-induced toxicity(the former: UGT1A1 *6/*28, the latter: UGT1A1*6/*6), there was no alternative hopeful treatment other than FOLFIRINOX for them. Therefore, FOLFIRINOX was administered very carefully. Although both patients showed Grade 4 neutropenia during the initial course, it was controllable with G-CSF administration and following stepwise reduction of the irinotecan dose. Severe diarrhea and other adverse events were not observed in both cases. Since the determined regimen of FOLFIRINOX for patients with high-risk UGT1A1 polymorphisms has not been developed yet, it would be critical to accumulate and review an experience of FOLFIRINOX administration for these patients.

Abstract
The prognostic impacts of preoperative C-reactive protein (CRP) and interleukin (IL)-6 expression levels in patients with breast cancer remain controversial. A total of 55 female patients with invasive breast cancer were enrolled, and preoperative prognostic parameters including IL-6 and CRP were analyzed. Overall survival (OS) and recurrence-free survival (RFS) were estimated using the Kaplan-Meier method, and candidates' prognostic factors were examined using a Cox proportional hazard model. Using receiver operating characteristic curve analysis, IL-6 at 10.0 pg/ml and CRP at 0.12 mg/dl were determined as threshold values to predict OS and RFS, respectively. Patients with IL-6 ≥10.0 pg/ml had poorer OS compared with those with IL-6 <10.0 pg/ml (P=0.003), and patients with CRP ≥0.12 mg/dl had poorer RFS compared with those with CRP <0.12 mg/dl (P<0.001). Serum IL-6 level (hazard ratio, 13.230; 95% confidence interval, 1.285-136.214; P=0.030) and triple-negative subtype (hazard ratio, 11.739; 95% confidence interval, 1.415-97.362; P=0.023) were independent prognostic factors for OS, and CRP expression level was an independent prognostic factor for RFS in patients with breast cancer (hazard ratio, 18.571; 95% confidence interval, 2.240-153.949; P=0.007). In patients with invasive breast cancer, preoperative serum IL-6 and triple-negative subtype may be independent prognostic factors for OS, while for RFS, preoperative CRP may be a more accurate prognostic factor compared with those currently established.

Abstract
BACKGROUND Although annular pancreas concurrent with pancreaticobiliary maljunction has rarely been reported, some reports have pointed out a possibility that both anomalies have a common pathogenesis in pancreatic development. We herein report a case with pancreaticobiliary maljunction diagnosed long after surgical treatment for annular pancreas. CASE PRESENTATION A 34-year-old female, with a surgical history of duodenal obstruction due to annular pancreas in the neonatal period, was referred to our hospital for further examination of chronic pancreatitis. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed choledocholithiasis, pancreatic lithiasis, and pancreaticobiliary maljunction without biliary dilatation. Choledocholithotomy and cholecystectomy were performed, and highly elevated levels of amylase in bile from the common bile duct were found intraoperatively. CONCLUSION The present case highlights a possible association of pancreaticobiliary maljunction in a patient with annular pancreas.

Abstract
The identification of novel biomarkers for hepatocellular carcinoma (HCC) is of great importance in improving the outcome of patients with HCC. The present study aimed to determine the prognostic significance of the soluble intercellular adhesion molecule (sICAM)-1 in patients with HCC. The present study prospectively collected clinicopathological data from 36 patients with HCC who had undergone successful hepatectomy. An analysis using a receiver operating characteristic (ROC) curve was performed to determine the cut-off value for predicting prognosis. Overall survival (OS), recurrence-free survival (RFS) and potential prognostic factors were analyzed. The ROC curve analysis revealed a sICAM-1 cut-off value of 440 ng/ml. HCC patients with sICAM-1 ≥440 ng/ml exhibited a poorer OS and RFS than those with sICAM-1 <440 ng/ml (P=0.002). sICAM-1 ≥440 ng/ml (hazard ratio=3.623; 95% confidence interval: 1.145-11.458; P=0.028) and Child B (hazard ratio=1.514; 95% confidence interval: 1.066-2.150; P=0.021) were independent prognostic factors for OS, and sICAM-1 ≥440 ng/ml was an independent prognostic factor for RFS (hazard ratio=3.625; 95% confidence interval: 1.233-10.659; P=0.019). Serum sICAM-1 may be a promising predictor for the overall and recurrence-free survival of patients with HCC.

Abstract
AIMS We aimed to investigate the relationship of colorectal cancer prognosis and inflammatory parameters, including neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR), with reference to circulating myeloid-derived suppressor cells (MDSCs) in the current study. PATIENTS AND METHODS Thirty-five patients who underwent curative-intent surgery were enrolled. A receiver-operating characteristic curve (ROC) was used to assess the usefulness of candidates for prognostic factors. Recurrence-free survival (RFS) was calculated using the Kaplan-Meier method, and the candidates for prognostic factors were assessed by a Cox proportional hazard model. RESULTS ROC curve analyses determined cutoff values for NLR and LMR as 2.9 and 2.4, respectively. The percentage of MDSCs in patients with LMR ≤ 2.4 was statistically higher than in those with LMR > 2.4 (p = 0.012). The patients with LMR ≤ 2.4 exhibited a statistically lower RFS than those with LMR > 2.4 (p = 0.008). These results were also observed in patients with stage II + III disease. LMR was an independent prognostic factor of RFS in colorectal cancer patients (hazard ratio: 7.757, 95% confidence interval: 1.462-41.152, p = 0.016). CONCLUSION Lower LMR was associated with poor prognosis in colorectal cancer patients; whereas, higher circulating MDSCs were observed in patients with lower LMR.

Abstract
BACKGROUND C-reactive protein (CRP) has been reported to be associated with poorer prognosis in various malignancies. However, the relationship between CRP and differentiated thyroid carcinoma (DTC) remains to be elucidated. METHODS A total of 45 patients, including 32 patients with preoperative DTC and 13 DTC patients with metastatic disease, were included in the study. The relationships between CRP levels and clinicopathological features were retrospectively analyzed. RESULTS Analysis using a receiver operating characteristic curve revealed a preoperative CRP cutoff value of 0.155 mg/dL. Patients with preoperative CRP ≥ 0.155 mg/dL, those with T3 + T4, those with extrathyroidal invasion, or those with stage II, showed a statistically shorter recurrent-free survival than those with preoperative CRP < 0.155 mg/dL, those with T1 + T2, those without extrathyroidal invasion, or those with stage I (P = 0.001, P = 0.004, P = 0.024, and P = 0.025, respectively). Preoperative CRP ≥ 0.155 mg/dL was an independent prognostic factor for recurrent-free survival in the DTC patients (hazard ratio = 6.334, 95% confidence interval: 1.023-39.234, P = 0.037). The proportion of patients aged ≥55 y, and those with T3 + T4, was statistically higher in those with preoperative CRP ≥ 0.155 mg/dL than in those with preoperative CRP < 0.155 mg/dL (P = 0.037 and P = 0.038, respectively). CONCLUSIONS Higher preoperative CRP levels have a robust prognostic impact on recurrence-free survival in DTC patients. In addition, higher preoperative CRP levels were associated with age ≥ 55 y and T3 + T4.

Abstract
Pancreatic metastatic tumors from thyroid carcinoma are extremely rare. We report a case of an 80-year-old female with a pancreatic metastatic tumor derived from papillary thyroid carcinoma which was initially resected 158 months prior to detection of the metastatic pancreatic tumor. The patient has encountered cervical lymph-node metastasis on three occasions following the initial operation. Metastatic pancreatic lesions and cervical lymph nodes were first detected using 18-fluorodeoxyglucose positron-emission tomography/computed tomography, and she was preoperatively diagnosed using endoscopic ultrasound-guided fine-needle aspiration biopsy. A coin lesion, 10 mm in size, was detected in the left lung by chest computed tomography with no abnormal uptake in 18-fluorodeoxyglucose positron-emission tomography/computed tomography. Distal pancreatectomy and cervical lymph-node dissection were performed. Adjuvant chemotherapy with weekly paclitaxel was administered because anaplastic transformation had been detected in one of the cervical lymph nodes. The patient eventually died from multiple lung metastases 11 months after removing the metastatic pancreatic lesion. We reported a rare case of a pancreatic metastatic tumor from thyroid carcinoma, and found that 18-fluorodeoxyglucose positron-emission tomography/computed tomography and endoscopic ultrasound-guided fine-needle aspiration biopsy are useful for preoperatively diagnosing tumors.

Abstract
BACKGROUND Liver fibrosis is a risk factor for hepatectomy but cannot be determined accurately before hepatectomy because diagnostic procedures are too invasive. Magnetic resonance elastography (MRE) can determine liver stiffness (LS), a surrogate marker for assessing liver fibrosis, non-invasively. The aim of this study was to investigate whether the LS value determined by MRE is predictive of major complications after hepatectomy. METHODS This prospective study enrolled consecutive patients who underwent hepatic resection between April 2013 and August 2016. LS values were measured by imaging shear waves by MRE in the liver before hepatectomy. The primary endpoint was major complications, defined as Clavien-Dindo grade IIIa or above. Logistic regression analysis identified independent predictive factors, from which a logistic model to estimate the probability of major complications was constructed. RESULTS A total of 96 patients were included in the study. Major complications were observed in 15 patients (16 per cent). Multivariable logistic analysis confirmed that higher LS value (P = 0·021) and serum albumin level (P = 0·009) were independent predictive factors for major complications after hepatectomy. Receiver operating characteristic (ROC) analysis showed that the best LS cut-off value was 4·3 kPa for detecting major complications, comparable to liver fibrosis grade F4, with a sensitivity of 80 per cent and specificity of 82 per cent. A logistic model using the LS value and serum albumin level to estimate the probability of major complications was constructed; the area under the ROC curve for predicting major complications was 0·84. CONCLUSION The LS value determined by MRE in patients undergoing hepatectomy was an independent predictive factor for major complications.

Abstract
We hereby report a case of long-term survival of metastatic and recurrent duodenal gastrointestinal stromal tumor(GIST) treated with multimodality managements. A 59-year-old man was diagnosed with duodenal GIST and underwent surgical resection of a primary lesion of the duodenum. Since the pathological findings on mitotic rate indicated its high risk of recurrence, the systemic treatment by imatinib mesylate was given shortly after the surgery. Six months later, metastatic lesions being considered to be imatinib-resistant were observed in the remnant liver. Since there were no other drugs available for GISTs in clinic at that time, surgery of central bisegmentectomy with partial resection of the liver was performed to eliminate all metastatic lesions. However, recurrences had been repeatedly diagnosed afterward. In response to them, four more surgery for recurrent liver or peritoneal tumors, two transcatheter arterial chemoembolizations(TACE)and one radiofrequency ablation(RFA)were performed on the basis of its resectability. Sunitinib malate had been given since it was approved for imatinib-resistant GISTs in clinic. Eventually, as long as 99 months had passed since we observed the first evidence of the resistance to imatinib mesylate when he died from the GIST.

Abstract
We hereby report a case of long-term survival of the pancreatic tail cancer with a synchronous small liver metastasis. A 62- year-old male with pancreatic tail cancer was incidentally diagnosed with single tiny metastasis in the left medial section of the liver duringthe distal pancreatectomy. The lesion was also resected together with primary lesion. Since then, systemic chemotherapies such as gemcitabine(GEM)plus S-1 combination therapy, GEM alone therapy and S-1 alone therapy had been given to escape from recurrence. However, the recurrences were found in the liver at 21 months after surgery. Left hepatectomy was performed for metastatic lesions. Afterwards, proton radiation therapy was twice performed for the metastatic lesions in the liver which were unable to be removed by surgery alone. Partial resection of transverse colon was also needed to be performed for the bowel obstruction caused by recurrence on the surgical margin of the liver. Systemic chemotherapies includingS -1 therapy, FOLFIRINOX therapy and GEM plus nab-paclitaxel therapy have been continued throughout his entire treatment history after recurrence. He has been keepingin good physical condition with these multidisciplinary therapies, even though 51 months have passed since the first evidence of liver metastasis was diagnosed.

Abstract
BACKGROUND/AIM Pancreatobiliary cancer is a disease associated with a dismal prognosis and limited treatment options. The aim of the present study was to clarify the usefulness of circulating galectin-3 in pancreatobiliary cancer. PATIENTS AND METHODS We examined serum galectin-3 concentrations in 45 patients with pancreatobiliary cancer. Receiver operating characteristic curves were utilized to evaluate the accuracy of circulating galectin-3 to discriminate pancreatobiliary cancer patients from controls and predict the prognostic outcomes. RESULTS Circulating galectin-3 had diagnostic value at the cut-off level of 6.2 ng/ml, and the patients' overall survival was predictable at the cut-off level of 10.3 ng/ml. Furthermore, circulating galectin-3 ≥10.3 ng/ml was an independent prognostic marker in pancreatobiliary cancer. Regarding biliary cancer, higher galectin-3 was associated with malnutrition. On the other hand, regarding pancreatic cancer, higher galectin-3 levels were associated with higher inflammatory parameters. CONCLUSION Galectin-3 can be a useful biomarker in patients with pancreatobiliary cancer.

Abstract
Acinar cell cystadenocarcinoma is a rare malignant epithelial neoplasm of the pancreas with a diffusely cystic, gross architecture in which the cysts are lined with neoplastic epithelial cells that demonstrate evidence of pancreatic exocrine enzyme production. This is the 10th case that has been reported in the literature. A 77-year-old male complaining of left hypochondrial pain was referred to our hospital for treatment of a pancreatic tumor. A huge, honeycomb-structured tumor was detected in the pancreatic tail. Distal pancreatectomy with total resection of the residual stomach and partial resection of the transverse colon were performed. Microscopically, there were variably sized cystic lesions in the tumor. Immunohistochemical examinations revealed that tumor cells were positive for alpha 1-antichymotrypsin and alpha 1-trypsin, showing that tumor cells had features of pancreatic acinar cells. Thus, the tumor was diagnosed as acinar cell cystadenocarcinoma. Herein, we report a rare case with acinar cell cystadenocarcinoma, which is the 10th case reported in the literature based on a PubMed search. We managed to resect the tumor completely by distal pancreatectomy with total resection of the residual stomach and partial resection of the transverse colon. The patient is still alive 26 months after surgery without any recurrence after 1 year of adjuvant chemotherapy with S-1.

Abstract
Purpose/Aim: Although several prognostic factors for extrahepatic cholangiocarcinoma (EHC) have been reported, preoperative prognostic factors have yet to be established. We investigated the serum concentration of angiogenic, inflammatory, and nutritional parameters. MATERIALS AND METHODS Twenty-five patients with EHC were enrolled before starting treatment. Preoperative prognostic factors were identified using multivariate analyses. RESULTS The serum soluble intercellular adhesion molecule-1 (sICAM-1) levels were significantly higher in the patients with EHC (436.0 ± 43.2 ng/ml) than in the healthy volunteers (228.6 ± 22.0 ng/ml) (p <.001). In addition, the serum IL-6 levels were significantly higher in the patients (18.0 ± 5.6 pg/ml) than in the healthy volunteers (5.7 ± 0.8 pg/ml) (p <.05). The serum IL-6 and sICAM-1 showed a strong correlation (r = 0.559) in the patients with EHC (p <.01). The serum IL-6 (area under the curve = 0.764, p =.030, cut-off level = 11.6) and sICAM-1 (area under the curve = 0.818, p =.007, cutoff level = 322.6) were revealed to be useful as prognostic factors by the receiver operating characteristic curves. The high IL-6 group and the high sICAM-1 group showed poorer DSS than those of the respective low groups. In the multivariate analysis, IL-6 (hazard ratio: 1.050, 95% confidence interval: 1.002-1.100, p =.043) and sICAM-1 (hazard ratio: 1.009, 95% confidence interval: 1.002-1.015, p =.009) were independent prognostic factors for DSS. CONCLUSIONS IL-6 and sICAM-1 were independent preoperative prognostic factors in EHC patients, causing continuous inflammation and malnutrition in collaboration with other pro-angiogenic factors.

Abstract
Galectin-3 has been reported to be associated with the prognosis of patients with various malignancies; however, it has not yet been investigated in patients with extrahepatic cholangiocarcinoma (EHCC). Expression of galectin-3 was retrospectively examined in 58 patients with EHCC: 21 with perihilar cholangiocarcinoma and 37 with distal cholangiocarcinoma (DCC). The Cox proportional hazard model was used to identify independent prognostic factors. Intranuclear accumulation of galectin-3 (gal-3-INA) was associated with poorer overall survival (OS) in all patients (P=0.003), as well as in patients with DCC (P=0.004). Patients with gal-3-INA also exhibited a poorer disease-free survival (DFS) than those without gal-3-INA in all patients with EHCC (P<0.001), and in patients with DCC (P<0.001). Gal-3-INA was an independent prognostic factor of OS and DFS in all patients [OS: Hazard ratio (HR), 4.470; 95% confidence interval (CI), 1.759–11.357; P=0.002; and DFS: HR, 5.116; 95% CI, 2.025–12.925; P=0.001]. Gal-3-INA was also an independent prognostic factor in patients with DCC (OS: HR, 2.979; 95% CI, 1.035–8.570; P=0.043; and DFS: HR, 6.773; 95% CI, 1.558–29.439; P=0.011). In the analysis of patients with DCC, the number of patients with high galectin-3 expression (P=0.038), recurrence (P<0.001), distant metastases (P<0.001), R0 status (P=0.029) or microscopic vascular invasion (P=0.019) was significantly higher in the gal-3-INA-positive group than in the gal-3-INA-negative group. In conclusion, gal-3-INA was identified as a strong prognostic factor for OS and DFS in patients with DCC.

Abstract
Background Multiple endocrine neoplasia type 1 (MEN1) is an autosomal-dominant inherited disorder that is classically characterized by the presence of neoplastic lesions of the parathyroid glands, the anterior pituitary gland, and the pancreas. However, MEN1 with concomitant pheochromocytoma is extremely rare. Case report We report a case of MEN1 concomitant with pheochromocytoma. A 44-year-old Japanese man, who had undergone total parathyroidectomy due to primary hyperparathyroidism at the age of 18, was referred to our hospital with a complaint of a large abdominal tumor. He was diagnosed as having a giant insulinoma (maximum diameter 18 cm) in the pancreatic tail, five other non-functional neuroendocrine tumors in the pancreatic body and tail, multiple liver metastases of pancreatic neuroendocrine tumors, a pituitary prolactinoma, non-functional adrenal cortical adenomas, a pheochromocytoma in addition to a subcutaneous neurofibroma, and a cutaneous fibroma. The genetic screening revealed a deletion mutation at codons 83–84 in exon 2 of the MEN1 gene. He underwent distal pancreatectomy, splenectomy, cholecystectomy, right adrenalectomy, abdominal subcutaneous tumor excision, and cutaneous tumor biopsy for the purpose of tumor volume reduction. Extended right posterior segmentectomy with partial hepatectomy of S2, S3, and S8 was performed to resect residual tumors 9 months after the initial surgery. Although a newly formed liver metastasis was found 19 months after the hepatectomy, he is still alive 4 years and 4 months after the initial surgery. Conclusions We reported an extremely rare case of giant insulinoma and simultaneous occurrence of pheochromocytoma and adrenal cortical adenoma in the ipsilateral adrenal gland in a patient clinically and genetically diagnosed as having MEN1.

Abstract
Galectin-3, a β-galactoside-binding lectin, exhibits pleiotropic biological functions and has a role as one of the immunological modulators. However, the associations between circulating galectin-3 and immunological, inflammatory and nutritional parameters have not yet been fully elucidated. The serum concentration of galectin-3 was examined in association with interleukin-10 (IL-10), IL-12 and IL17 production, lymphocyte stimulation, neutrophil/lymphocyte ratio (NLR), white blood cell count (WBC), C-reactive protein (CRP) and rapid turnover proteins, including retinol-binding protein (RBP), prealbumin (PA) and transferrin (TF) in 50 patients with untreated colorectal cancers. Significant increases (P<0.05) were observed in the serum galectin-3 levels in patients with untreated colorectal cancer (9.6±4.5 ng/ml) compared with the normal controls (3.2±1.6 ng/ml). Higher serum galectin-3 concentrations were observed in patients with colon cancer (11.5±4.4 ng/ml) compared to in patients with rectal cancer (8.0±4.0 ng/ml) (P=0.005). The levels of circulating galectin-3 inversely correlated with the production of IL-10 (r=-0.59, P<0.001), and IL-12 (r=-0.69, P<0.001). Galectin-3 concentration also inversely correlated with the lymphocyte stimulation assay stimulation index (r=-0.42, P=0.021). However, the level of serum galectin-3 correlated with IL-17 production (r=0.67, P<0.001). Serum galectin-3 levels exhibited significant correlations with NLR (r=0.41, P=0.009), WBC (r=0.32, P=0.035), and CRP (r=0.63, P<0.001), and statistically significant inverse correlations with RBP (r=-0.45, P=0.002), PA (r=-0.46, P=0.001) and TF (r=-0.72, P<0.001). Galectin-3 may be one of the key factors in the regulation of immunological, inflammatory and nutritional conditions.

Abstract
Despite strict criteria for the observation of intraductal papillary mucinous neoplasm (IPMN), it remains difficult to distinguish invasive IPMN from non-invasive IPMN. The aim of the present study was to identify an indicator of invasive IPMN. The present study retrospectively evaluated 53 patients (28 with non-invasive and 25 with invasive IPMN) who underwent resection of IPMN, and examined the usefulness of the MIB-1 labeling index as an indicator of invasive IPMN. The MIB-1 labeling indexes in patients with invasive IPMN were significantly higher compared with those with non-invasive IPMN (P<0.001). A receiver operating characteristic curve revealed that the area under the curve was 0.822. These results suggested that a cut-off level for the MIB-1 labeling index should be set to 15.5% to distinguish invasive from non-invasive IPMN. A multivariate analysis using a logistic regression model revealed the MIB-1 labeling index (hazard ratio, 18.692; 95% confidential interval, 4.171-83.760; P<0.001) and the existence of mural nodules (hazard ratio, 6.187, 95% confidential interval, 1.039-36.861; P=0.045) were predictive factors for invasive IPMN. However, no statistically significant differences were observed between patients with a lower MIB-1 labeling index and patients with a higher MIB-1 labeling index (P=0.798). The MIB-1 labeling index must be considered as a candidate for the classification of IPMN.

Abstract
BACKGROUND FOLFIRI and FOLFOX have shown equivalent efficacy for metastatic colorectal cancer (mCRC), but their comparative effectiveness is unknown when combined with bevacizumab. PATIENTS AND METHODS WJOG4407G was a randomized, open-label, phase III trial conducted in Japan. Patients with previously untreated mCRC were randomized 1:1 to receive either FOLFIRI plus bevacizumab (FOLFIRI + Bev) or mFOLFOX6 plus bevacizumab (mFOLFOX6 + Bev), stratified by institution, adjuvant chemotherapy, and liver-limited disease. The primary end point was non-inferiority of FOLFIRI + Bev to mFOLFOX6 + Bev in progression-free survival (PFS), with an expected hazard ratio (HR) of 0.9 and non-inferiority margin of 1.25 (power 0.85, one-sided α-error 0.025). The secondary end points were response rate (RR), overall survival (OS), safety, and quality of life (QoL) during 18 months. This trial is registered to the University Hospital Medical Information Network, number UMIN000001396. RESULTS Among 402 patients enrolled from September 2008 to January 2012, 395 patients were eligible for efficacy analysis. The median PFS for FOLFIRI + Bev (n = 197) and mFOLFOX6 + Bev (n = 198) were 12.1 and 10.7 months, respectively [HR, 0.905; 95% confidence interval (CI) 0.723-1.133; P = 0.003 for non-inferiority]. The median OS for FOLFIRI + Bev and mFOLFOX6 + Bev were 31.4 and 30.1 months, respectively (HR, 0.990; 95% CI 0.785-1.249). The best overall RRs were 64% for FOLFIRI + Bev and 62% for mFOLFOX6 + Bev. The common grade 3 or higher adverse events were leukopenia (11% in FOLFIRI + Bev/5% in mFOLFOX6 + Bev), neutropenia (46%/35%), diarrhea (9%/5%), febrile neutropenia (5%/2%), peripheral neuropathy (0%/22%), and venous thromboembolism (6%/2%). The QoL assessed by FACT-C (TOI-PFC) and FACT/GOG-Ntx was favorable for FOLFIRI + Bev during 18 months. CONCLUSION FOLFIRI plus bevacizumab was non-inferior for PFS, compared with mFOLFOX6 plus bevacizumab, as the first-line systemic treatment for mCRC. CLINICAL TRIALS NUMBER UMIN000001396.

Abstract
667 Background: Cancer cachexia is a mixed and multiple factorial condition and commonly seen in patients with advanced cancer, and has long been reported that host-immune function is critically participated. Chronic inflammation plays a key role in the progress of malignant diseases and has been reported to relate with immune suppression and nutritional impairment seen in patients with advanced diseases. Methods: Peripheral blood mononuclear cells (PBMC) were collected from 18 normal healthy volunteers and 112 patients with gastrointestinal cancer. These cells were used for the detection of MDSC (myeloid-derived suppressor cells: CD11b+CD14-CD33+) by flow cytometry. PBMC was also used for the PHA-blastogenesis of lymphocytes which is a marker of cell mediated immunity (stimulation indices: SI) and for the production assay of cytokines including IFN-G, IL-6 and IL-10. Serum levels of soluble cytokine receptors including sIL-2R and sTNF-R1, and anti-inflammatory molecules such as IL-10 and IL-1 receptor antagonist (IL-1RA) were also measured. For the evaluation of nutritional status, serum concentrations of rapid turnover protein (RTP) including prealbumin, transferrin and retinol binding protein was measured. NLR (neutrophil/lymphocyte ratio) was calculated and used as a marker of chronic inflammation. Results: The circulating levels of MDSC was significantly increased in esophageal, gastric and colorectal carcinomas than in normal volunteer and significantly inversely correlated with serum concentration of RTP and with SI, and correlated with markers for inflammation. The levels of sIL-2R and sTNF-R1 were increased in patients with gastric and colorectal and inversely correlated with the levels of RTP and SI. In patients with cachexia, serum concentrations of IL-10 were increased and the production of IFN-G was decreased. Conclusions: It is suggested that suppression of cell-mediated immune function exists in patients with cancer cachexia and the immunological mechanisms of nutritional damages in these patients are even partially driven by Th2-dominant condition of CD4(+) cells and MDSC. These complicated mechanisms are also involved in inflammation-related immunological condition such as SIRS and CARS.

Abstract
Polarization holography is the superposition of differently polarized beams. Due to its ability to record the polarization states, some extraordinary optical phenomena were found in the polarization holography. For example, the recently reported null-reconstruction phenomenon in polarization volume hologram is odd for the conventional holography which only records the amplitude and phase. In this paper, we perform a thorough investigation of the null reconstruction of polarization hologram recorded by orthogonal circularly polarized waves. To explore the mechanism behind this phenomenon, an interferometry was built to measure the phase difference between the same polarized components within the reconstructed wave. The phase difference of π was secured in our experiment, indicating a destructive interfering effect, which nicely explains the extraordinary null reconstruction observed in the polarization hologram.

Abstract
OBJECTIVES FOLFIRINOX is an effective therapy for unresectable advanced pancreatic cancer. However, FOLFIRINOX has side effects of blood and gastrointestinal toxicity. Diarrhea, one of the side effects of CPT-11, sometimes becomes serious. We studied whether Hange-shashin-to could prevent diarrhea caused by CPT-11. METHODS Seven patients who were diagnosed with unresectable pancreatic cancer, either Stage Ⅳor recurrent disease, were enrolled. They took 2.5 g of Hange-shashin-to before each meal starting one day before FOLFIRINOX, and continued taking it for one week. We examined the occurrence of diarrhea by using CTCAE retrospectively. RESULTS The median age was 61 years. The median number of chemotherapy courses was 4. The frequency of diarrhea was lower, compared to the results of ACCORD11 trial and the domestic phaseⅡ clinical trials. In addition, Grade 3 or more serious diarrhea was not observed, even in the patients with genetic polymorphisms of UGT1A1. CONCLUSION The incidence of diarrhea in patients treated with Hange-shashin-to in our department was lower compared to the ACCORD11 trial and domestic phase Ⅱ clinical trials. Hange-shashin-to is useful to allay the severity of diarrhea caused by CPT-11 in FOLFIRINOX therapy.

Abstract
A 69-year-old woman was diagnosed with liver dysfunction on blood testing in a nearby clinic. Computed tomography revealed stenosis of the hilar bile duct. Accordingly, an endoscopic nasobiliary drainage tube was inserted in the left hepatic duct and she was referred to our hospital for diagnostic examinations and treatment. The endoscopic retrograde cholangiopancreatography findings revealed obstruction of the cystic duct and stenosis of the hilar bile duct due to inflammation of the cystic duct or inflammation of the clamping type by cholecystitis. Considering the possibility of malignant tumor, surgical operation was performed. Radical resection was considered impossible and we instead performed cholecystectomy and resection of a bile duct wall specimen for diagnosis. The pathological diagnosis was poorly differentiated tubular adenocarcinoma. The patient was treated with gemcitabine as systemic chemotherapy for unresectable hilar bile duct cancer. Currently, 78 months after the start of chemotherapy, the patient is alive and well, without tumor progression.

Abstract
Neurobiological and genetic mechanisms underlying increased intake of and preference for nutritive sugars over non-nutritive sweeteners are not fully understood. We examined the roles of subnuclei of the amygdala in the shift in preference for a nutritive sugar. Food-deprived mice alternately received caloric sucrose (1.0 M) on odd-numbered training days and a non-caloric artificial sweetener (2.5 mM saccharin) on even-numbered training days. During training, mice with sham lesions of the basolateral (BLA) or central (CeA) nucleus of the amygdala increased their intake of 1.0 M sucrose, but not saccharin. Trained mice with sham lesions showed a significant shift in preference toward less concentrated sucrose (0.075 M) over the saccharin in a two-bottle choice test, although the mice showed an equivalent preference for these sweeteners before training. No increased intake of or preference for sucrose before and after the alternating training was observed in non-food-deprived mice. Excitotoxic lesions centered in the BLA impaired the increase in 1.0M sucrose intake and shift in preference toward 0.075 M sucrose over saccharin. Microlesions with iontophoretic excitotoxin injections into the CeA did not block the training-dependent changes. These results suggest that food-deprived animals selectively shift their preference for a caloric sugar over a non-caloric sweetener through the alternate consumption of caloric and non-caloric sweet substances. The present data also suggest that the BLA, but not CeA, plays a role in the selective shift in sweetener preference.

Abstract
Cyclin D1 expression is precisely controlled during cell-cycle progression. However, repeated exposure to low-dose fractionated radiation (FR) abrogates cell cycle-dependent cyclin D1 degradation by constitutive activation of AKT survival signaling in normal human fibroblasts. The resulting abnormal nuclear cyclin D1 accumulation induces defects in DNA replication and resulting DNA double-strand breaks, and is associated with induction of genomic instability in low-dose irradiated cells. Here, we investigated the role of DNA damage signaling against such perturbed cell-cycle control of cyclin D1 expression. Nuclear cyclin D1 accumulation was induced within 7 days after low-dose FR (0.01 Gy or 0.05 Gy per fraction) in ATM-deficient cells (AT5BIVA), but appeared later in AT5BIVA cells harboring human ATM cDNA. Thus, ATM prevents abnormal nuclear cyclin D1 accumulation at early time points after low-dose FR. We further demonstrated that ATM-mediated downregulation of protein phosphatase 2A activity caused activation of the AKT/cyclin D1 pathway after long-term FR. Perturbation of cyclin D1 expression induced Rad51 foci that indicate homologous recombination repair (HRR) in control cells, while ATM- and NBS1-deficient cells (GM7166) failed to induce Rad51 foci after long-term low-dose FR. After 21 days of FR, NBS1- and ATM-deficient cells showed a decrease in nuclear cyclin D1-positive cells, and an increase in apoptotic cells. Similarly, inhibition of ATM with KU55933 abrogated nuclear cyclin D1 accumulation by induction of apoptosis in ATM-complemented cells exposed to low-dose FR. In conclusion, we here demonstrate that ATM is involved in controlling cyclin D1 levels after low-dose FR. DNA damage signaling mitigates the harmful effects of low-dose long-term FR by suppression of cell death induced by perturbation of cyclin D1 expression.

Abstract
An inflammatory pseudotumor (IPT) of the liver is a rare benign disorder.As its characteristics based on computer tomography and magnetic resonance imaging findings are still unclear, it is difficult to distinguish IPT from malignant diseases of the liver.Herein, we report a case of IPT of the liver concurrent with advanced gallbladder cancer, which we could not diagnose preoperatively.First, we performed lateral segmentectomy of the liver.Second, a radical operation for gallbladder cancer was performed after confirming that the hepatic tumor was IPT via intraoperative pathological diagnosis.Therefore, modalities less invasive than surgical resection should be innovated, even though surgical resection is accurate.

Abstract
BACKGROUND/AIMS Hepaticojejunostomy (HJ) has remained an important component of many surgical procedures. Biliary leaks after HJ represent a major complication carrying a high risk for prolonged hospital stay, biliary peritonitis, and the need for placing interventional drains or even conducting a re-laparotomy. The aims of this study were to define predictive factors associated with the incidence of bile leaks and to compare the results of anastomotic stenting of HJ with those obtained without stenting. METHODOLOGY A retrospective study was performed on patients who underwent HJ between January 2000 and December 2010 at Gunma University Hospital, Department of Surgery I. A bile leak was defined as a bilirubin concentration in the drains exceeding serum bilirubin or occurrence of a biloma requiring drainage. Transanastomotic techniques for HJ were compared between the stented (external diverting stent, internal stent) and non-stented groups with respect to bile leaks. RESULTS An HJ leak was demonstrated in 15 patients (12.4%); the overall surgical morbidity was 29.2%. The incidence of clinically relevant bile leaks after HJ was significantly associated with simultaneous liver resection, preoperative biliary drainage (PBD) and the placement of stents through the anastomosis. CONCLUSIONS We conclude that the routine use of a biliary stent is not justified before and after surgery. We consider that stenting is unnecessary when a full anastomosis of the bile duct to the jejuna mucosa is performed. However, when an anastomosis of the intrahepatic bile duct to the jejuna mucosa is performed, more careful method must be exercised during an anastomotic procedure.

Abstract
Background: Tropomyosin-related receptor kinase B (TrkB) promotes proliferation and invasion, relating to poor prognosis of various malignancies. We examined the role of TrkB at the invasive front of gastric cancer (GC) and its association with tumour cell dedifferentiation and tumour budding. Methods: Immunoreactive TrkB was evaluated at the tumour centre and margin using whole-tissue sections of 320 GC patients. Tumour cell dedifferentiation was defined as higher histologic grade at the tumour margin than the surface or tumour centre. Tumour budding was also scored on cytokeratin-stained sections. Results: Sixty-five patients (20%) showed higher TrkB expression at the invasive front (TrkB expression was higher at the tumour margin than tumour centre). It was significantly associated with several aggressive phenotypes in the full cohort (n=320). It showed a prognostic significance in test subgroup (n=98) and was identified as an independent prognostic factor (HR=2.09; 95% CI: 1.26–3.53) by multivariate analysis in validation subgroup (n=222). Twenty-one patients showed tumour cell dedifferentiation. In predominantly differentiated tumour, higher TrkB at the invasive front was significantly associated with tumour budding rather than tumour cell dedifferentiation. Conclusions: Assessment of immunoreactive TrkB at the invasive front by whole-tissue sections provides prognostic information for GC patients.

Abstract
BACKGROUND To extend the usefulness of laparoscopic operations, a secure and easy method for the ligation of large vessels is needed. Herein we describe a novel ligation forceps that can be used as a ligature carrier and knot pusher. METHODS A 2-0 suture thread with a knot already tied near one end is hooked in the upper jaw of a novel ligation forceps. After the lower jaw is passed under the vessel or cystic duct, the forceps is closed. When one end of the thread is withdrawn, the knot is trapped in the indentation built into the lower jaw; the ligature is then passed under the pedicle. An extracorporeal ligation can then be performed continuously by the same forceps. RESULTS The origins of large vessels were ligated safely and easily with this device during 65 laparoscopic procedures (four total colectomies, 12 colectomies, and 49 gastrectomies). Following temporary hemostasis of accidental bleeding with clamping forceps, ligation hemostasis can also be performed using this instrument. CONCLUSION This novel ligation forceps permits the secure ligation of vessels or a cystic duct without the need for another device. The proposed method is both easy and inexpensive.

Abstract
514 Background: Vascular endothelial growth factor (VEGF) reportedly plays an important role in the progression of malignant neoplasms, and have been reported to induce myeloid-derived suppressor cells (MDSC) that appears in cancer and inflammation. Methods: Blood samples were collected from 57 patients, including 8 with esophageal cancer, 20 with gastric cancer, 29 with colorectal cancer, and from 18 healthy volunteers. We measured serum concentrations of VEGF and analyzed correlations with nutritional damage, immune suppression and systemic inflammation. As markers of immune function, IL-12 production of PBMC and MDSC (CD 11b+, CD14-, CD33+) were measured. Serum concentrations of albumin and rapid turnover protein were measured as a marker of nutritional status. Results: A significant increase in serum levels was seen in patients with esophageal, gastric, and colorectal cancers compared to healthy volunteers. Levels of VEGF were inversely correlated with serum concentrations of albumin, prealbumin and retinol-binding protein. Serum concentrations of VEGF were inversely correlated with the production of interleukin (IL)-12 and correlated with MDSC. VEGF levels also correlated with neutrophil count and neutrophil/lymphocyte count, and correlated inversely with lymphocyte count. Serum VEGF levels were then divided about a cutoff of 500 pg/ml, with levels of prealbumin and retinol-binding protein significantly decreased in patients with higher VEGF levels. Stimulation index and IL-12 production were significantly decreased in the group with higher VEGF levels, and MDSC counts tended to be higher in this group. Conclusions: These results demonstrated that increased production of VEGF correlated with systemic inflammation, nutritional impairment and inhibition of cell-mediated immunity involving MDSCs. An inactivation of dendritic cells may be occurring by the activation of MDSC. Anti-VEGF therapy may be of importance in treating digestive system cancers.

Abstract
BACKGROUND AND STUDY AIMS Acute colorectal obstruction (ACO) often accompanies colorectal cancer (CRC) and requires urgent treatment, but achieving elective laparoscopy-assisted colectomy (LAC) is difficult in this setting. The aim of the current study was to assess the clinical outcomes of a transanal tube (Dennis colorectal tube [DCT]) for CRC with ACO, focusing in particular on the impact of the DCT on subsequent elective LAC. PATIENTS AND METHODS Among 1142 patients who underwent surgery for CRC between January 2007 and December 2011, 92 patients with ACO were identified retrospectively. Of these 92 patients, the DCT procedure was performed in 66 patients who fulfilled the indications for DCT, and these patients were included in the study. RESULTS All 66 patients presented with complete obstruction. Technical and clinical success rates for DCT were 93.9 % and 86.4 %, respectively. Perforation after DCT occurred in 4.5 % and the mortality rate was 1.5 %. The rate of LAC was 48.5 %, and the rate of primary stoma was 13.6 %. For curative stage II/III CRC with ACO, DCT resulted in a primary stoma rate of 13.6 %, a one-stage surgery rate of 90.9 %, a LAC rate of 50.0 %, and a 3-year survival rate of 73.1 %. For stage II/III CRC cases with clinical success by DCT, the one-stage surgery rate was 97.4 % and the LAC rate was 56.4 %. CONCLUSIONS DCT achieved a high rate of clinical success and enabled safe one-stage surgery and LAC for CRC with ACO. DCT followed by LAC is proposed as a promising non-invasive strategy for CRC with ACO.
