Abstract
Abstract
Background
Triglyceride (TG) deposit cardiomyovasculopathy (TGCV) is a novel cardiovascular disorder and was recently encoded as an orphan disease in Europe (ORPHA code: 565612). Defective intracellular lipolysis results in TG accumulation in the myocardium and coronary arteries in TGCV. The myocardial washout rate (WR) of iodine-123-β-methyl-p-iodophenylpentadecanoic acid (BMIPP) is an essential indicator to evaluate myocardial lipolysis in vivo, and decreased WR (<10%) of BMIPP is one of the essential items of diagnostic criteria for TGCV.
Purpose
To clarify clinical findings of TGCV including comorbid conditions and laboratory findings.
Methods
We enrolled 234 patients who underwent BMIPP scintigraphy between September 2015 and July 2019. The distributions of TGCV in each comorbidity, cardiac functions and laboratory findings were investigated.
Results
In total, 104 patients were diagnosed with definitive TGCV. The BMIPP WR of TGCV patients was −1.37±10.6%. TGCV patients had various comorbid conditions, including coronary artery disease (75%), diabetes mellitus (56%), and heart failure (21%). Left ventricular ejection fraction (LVEF) of TGCV patients was significantly lower than that of non-TGCV patients (38.1±18.0% vs. 43.6±18.9%, p-value=0.026). Moreover, among those who did not take lipid-lowering drugs, there was no difference in the serum TG level between TGCV and non-TGCV patients (TGCV: n=44, 127±84.6 mg/dL, non-TGCV: n=66, 133±70.7 mg/dL, p-value=0.73).
Conclusions
TGCV patients showed multiple coexistence of coronary artery disease, diabetes mellitus, or heart failure with lower LVEF. Serum TG level was not significantly different between TGCV and non-TGCV patients. Serum TG did not affect the intracellular TG accumulation in TGCV patients directly, and this result was consistent with the pathophysiological hypothesis that the TG accumulation in the myocardial cytoplasm is due to intracellular lipase dysfunction.

Abstract
PURPOSE Anastomotic leakage is a potential complication after colorectal surgery. We investigated the effects of oral antibiotics and a low-residue diet on the incidence of anastomotic leakage after left-sided colorectal surgery. METHODS Outcomes were retrospectively compared between 64 patients who underwent mechanical bowel preparation alone (group A) and 183 patients who underwent mechanical bowel preparation with addition of oral kanamycin and metronidazole (group B) on the day before left-sided colorectal surgery. After surgery, patients in group A received a normal diet containing dietary fiber and those in group B received a low-residue diet. The primary outcome was the incidence of anastomotic leakage. Secondary outcomes were rates of other postoperative complications, length of postoperative hospital stay, and laboratory data. RESULTS Anastomotic leakage, surgical site infection, and diarrhea were less common in group B than in group A (4.9% vs 18.8%, 6.6% vs 23.4%, and 25.7% vs 43.8%, respectively). Postoperative C-reactive protein levels were significantly lower in group B. The median postoperative hospital stay was significantly shorter in group B than in group A (8 days vs 9 days, P = 0.010). Adaptive double least absolute shrinkage and selection operator regression revealed that use of preoperative oral antibiotics and a postoperative low-residue diet were associated with lower incidence of anastomotic leakage (odds ratio 0.163, 95% confidence interval 0.062-0.430; P < 0.001). CONCLUSION Oral antibiotics and a low-residue diet reduced the incidence of anastomotic leakage and shortened the postoperative hospital stay by 1 day.

Abstract
BACKGROUND This study aimed to assess the safety and efficacy of carbon-ion radiotherapy (CIRT) for salvage of previously X-ray-irradiated (XRT) locally recurrent rectal cancer (LRRC). METHODS Between September 2005 and December 2017, 77 patients with LRRC were treated with CIRT re-irradiation. All the patients had received prior XRT with a median dose of 50.0 Gy (range 20-74 Gy), principally for neoadjuvant or adjuvant recurrence prophylaxis in 34 patients and for recurrence in 43 patients. The total CIRT dose of 70.4 Gy (RBE) (gray relative biologic effectiveness) was administered in 16 fixed fractions during 4 weeks (4.4 Gy [RBE] per fraction). RESULTS All the patients completed the scheduled treatment course. None of the patients received resection after CIRT. Acute grade 3 toxicities occurred for eight patients (10 %), including five grade 3 pelvic infections (2 involving pain and 1 involving neuropathy). Late grade 3 toxicities occurred for 16 patients (21 %): 13 with late grade 3 pelvic infections, 9 with gastrointestinal toxicity, 1 with skin toxicity, 2 with pain, and 4 with neuropathy. No grade 4+ toxicity was noted. The overall local control rates (infield + out-of-field recurrence) were 69 % at 3 years and 62 % at 5 years. In the planning target volume (PTV), the infield recurrence rates were 90 % and 87 % respectively. The control rates for regional recurrence were 85 % at 3 years and 81 % at 5 years. The median overall survival time was 47 months. The survival rates were 61 % at 3 years and 38 % at 5 years. CONCLUSION Carbon-ion re-irradiation of previously X-ray-irradiated locally recurrent rectal cancer appears to be safe and effective, providing good local control and survival advantage without unacceptable morbidity.

Abstract
Abstract
Background
Patients with chronic thromboembolic pulmonary hypertension (CTEPH) represent right ventricular (RV) enlargement and hypertrophy, which consequently increase the RV myocardial perfusion. Although the main energy source of myocardium is fatty acid, it remains unknown whether myocardial fatty acid metabolism is altered in loaded RV. Herein, we report a novel approach to assess the RV perfusion and fatty acid metabolism, which is called SPECT-guided planar imaging.
Purpose
To evaluate if SPECT-guided myocardial perfusion and metabolic fatty acid planar imaging reflects the severity of the pulmonary hypertension in patients with chronic thromboembolic pulmonary hypertension.
Methods
The study groups included 30 patients with CTEPH and 20 healthy controls. In these patients with CTEPH, 15 patients underwent pulmonary thromboendarterectomy (PEA). Mean pulmonary artery pressure (mPAP) by right heart catheterization was obtained in all CTEPH patients. 201Thallium (201Tl) and iodine-123-beta-methyl iodophenyl pentadecanoic acid (123I-BMIPP) planar myocardial imaging was performed in all participants. For the patients undergoing PEA, repetitive SPECT-guided 201Tl and 123I-BMIPP planar imaging was performed one year after the procedure. To assess the RV overload, the planar images were performed in left anterior oblique position, optimized to separate the RV from the left ventricular (LV) using SPECT-guided transverse imaging. We measured the total counts of 201Tl and 123I-BMIPP in both the RV and LV. Moreover, we calculated their relative counts of the RV to LV (abbreviated as HR/HL (Tl) and HR/HL (BMIPP), respectively) to determine the indices of myocardial perfusion and fatty acid metabolism, respectively.
Results
Both HR/HL (Tl) and HR/HL (BMIPP) were elevated in the CTEPH patients compared with control (0.62±0.14 vs. 0.36±0.07, p<0.01 and 0.57±0.14 vs. 0.34±0.06, p<0.01, respectively). In the CTEPH patients, average mPAP was 44.0±9.52 mmHg, which was correlated with HR/HL (Tl) (r=0.675, p<0.001) and HR/HL (BMIPP) (r=0.685, p<0.01). Furthermore, the decrease of average mPAP 1 year after PEA was positively associated with the decrease of HR/HL (Tl) (r=0.646, p<0.01) and HR/HL (BMIPP) (r=0.504, p<0.05) 1 year after PEA.
Conclusions
In patients with CTEPH, RV myocardial perfusion and fatty acid metabolism was upregulated and moderately correlated with mPAP. SPECT-guided 201Tl and 123I-BMIPP planar imaging is a novel and noninvasive imaging modality to assess the severity of PH.

Abstract
PURPOSE This randomized phase II trial compared tegafur-uracil/leucovorin (UFT/LV) plus oxaliplatin (TEGAFOX) to UFT/LV as adjuvant chemotherapy for patients with high-risk stage II/III colorectal cancer. METHODS From 2010 to April 2015, 159 patients who underwent curative resection were randomly assigned to receive TEGAFOX (85 mg/m2 oxaliplatin on days 1 and 15, 300 mg/m2/day UFT and 75 mg/day LV on days 1-28, every 35 days for five cycles) or UFT/LV. The primary study endpoint was disease-free survival. RESULTS The 3-year disease-free survival rate was 84.2% in the TEGAFOX arm, versus 62.1% for UFT/LV. The stratified hazard ratio for disease-free survival for TEGAFOX compared to UFT/LV was 0.338 (P < 0.01). The incidence of any-grade adverse events was significantly higher in the TEGAFOX arm (96.1%) than in the UFT/LV arm (76.6%; P < 0.01). The rates of any-grade neutropenia, thrombocytopenia, aspartate aminotransferase/alanine aminotransferase elevation, and peripheral sensory neuropathy were higher in the TEGAFOX group, whereas the incidence of grade ≥ 3 adverse events did not differ between the groups. CONCLUSIONS TEGAFOX is an additional adjuvant chemotherapy option for high-risk stage II/III colorectal cancer. TRIAL REGISTRATION UMIN ID: 000007696, date of registration: April 10, 2012.

Abstract
BACKGROUND AND PURPOSE Simulation computed tomography colonography(sCTC), which combines CTC and 3-dimensional vascular imaging, is popular for the surgery of colorectal cancer. We experience anomaly, called arc of Riolan(aR), rarely but its definition and details are unclear. Using sCTC, we identified aR and investigated the simulation of aR-conserving high ligation. PATIENT AND METHOD The patients were 3 cases of sigmoid colorectal cancer with aR in 369 patients who underwent sCTC before colorectal cancer surgery. We identified the running morphology of aR. And we classified Griffiths' point as presence(P)and absence(A). Narrow or mesh-shaped artery which were ischemic risk factors of intestinal tract was P groups and normal artery was A groups in the marginal artery of splenic flexure. We simulated aR-conserving lymph node dissection using sCTC. RESULT Case 1. The patient was 60-year-old man with rectal cancer, cT4aN1M0, Stage Ⅲa. The running morphology of aR was between the left branch of middle colic artery(MCA lt)and LCA. Griffiths point: P. Surgical simulation was D3 lymph node dissection with preservation of aR and high ligation of IMA. Pathological findings was pT3N1M0, Stage Ⅲa. Case 2. The patient was 65-year-old woman with sigmoid colon cancer, cT3N2M0, Stage Ⅲb. The running morphology of aR was between MCA lt and IMA. Griffiths point: P. Surgical simulation was D3 lymph node dissection with preservation of aR and high ligation of IMA. Pathological findings was pT3N2M0, Stage Ⅲb. Case 3. The patient was 75-year-old woman with sigmoid colon cancer, cT1bN0M0, Stage Ⅰ. The running morphology of aR was between first jejunal artery and IMA. Griffiths point: A. Surgical simulation was D3 lymph node dissection with preservation of aR and high ligation of IMA. Pathological findings was pT1bN0M0, Stage Ⅲb. CONCLUSION Using sCTC, we could identify the various running morphology of aR and simulate aR-conserving lymph node dissection in high ligation.

Abstract
The case was a woman in her 50s. Total pelvic resection was performed for advanced rectal cancer(cT4b[vagina]N3M0, cStage Ⅲc), after neoadjuvant chemoradiation therapy. Five months after the operation, she was unable to stand due to severe back pain. Spinal MRI revealed multiple bone metastases and lumbar fractures. In addition, dysphagia and dysarthria rapidly progressed almost simultaneously with back pain. Initially, brain metastasis was suspected, but head MRI revealed Collet-Sicard syndrome due to skull base metastasis. Irradiation to the skull base and high cervical spine, thoracolumbar spine was started. After irradiation, her back pain and cranial nerve symptoms improved. She was discharged and received palliative treatment. About a month after discharge, she was hospitalized for recurrent dysphagia and died on day 5 of hospitalization. Collet-Sicard syndrome is caused by damage to the cranial nerves Ⅸ to Ⅻ and is often caused by a tumor. Trauma, vasculitis, and internal carotid artery dissection have been reported as other causes. Symptoms such as hoarseness, dysarthria, tongue atrophy, dysphagia, and headache have been reported. Collet-Sicard syndrome due to bone metastasis of colorectal cancer were very rare, and we found only one other report. We report our case with some literature considerations.

Abstract
AIM To show the treatment outcomes of disseminated nodule resection for peritoneal metastasis of colorectal cancer and describe the details of cured cases. PATIENTS AND METHODS From January 2001 to December 2016, patients who underwent disseminated nodule resection of colorectal adenocarcinoma with no macroscopic residual tumor in our institution were retrospectively analyzed for clinicopathological factors associated with prognosis. RESULTS Forty-one cases were included in this study. The 3-year relapse-free survival was 12.5%, and the 5-year overall survival was 38.4%. In a multivariate analysis, lack of post-operative adjuvant chemotherapy and pre-operative carbohydrate antigen 19-9 over 100 IU/l were extracted as independent factors associated with short relapse-free survival, respectively. Among 41 cases, 32 were followed-up 5 years after surgery and five (15.6%) survived without relapse and were regarded as 'cured'. CONCLUSION More than a few cases of colorectal peritoneal metastasis, which is thought to be difficult to cure, were cured by resection of disseminated nodules without resorting to highly invasive treatment.

Abstract
Krüppel‐like factor 5 (KLF5) plays an oncogenic role and has diverse functions in cancer cells. However, correlation between KLF5 and clinical outcome has not been determined in patients with colorectal cancer and colorectal liver metastasis. Herein, we analyzed 65 patients with colorectal cancer who developed colorectal liver metastasis. Clinical effects were assessed through immunohistochemical analysis of primary colorectal cancer lesions and metastatic liver lesions. High expression of KLF5 in these tissues correlated with the presence of vascular invasion, elevated serum carbohydrate antigen 19‐9 levels, large diameters of metastatic liver tumors, and poor prognosis following surgery. Multivariate analyses revealed that high expression of KLF5 was an independent prognostic factor. Increased expression of KLF5 in both colorectal cancer primaries and colorectal liver metastasis was significantly associated with shorter overall survival time and time to surgical failure. Krüppel‐like factor 5 expression positively correlated with Ki‐67 and c‐Myc expression in colorectal cancer tissues. In vitro experiments with colon cancer cell lines showed that siRNA knockdown of KLF5 inhibited cell proliferation. Western blot analyses revealed that knockdown of KLF5 expression reduced cyclin D1 and c‐Myc expression. It also impaired the stem cell‐like properties of cancer cells in tumorsphere formation assays. Furthermore, anoikis assay indicated that KLF5 contributed to anoikis resistance. High KLF5 expression is associated with poor prognosis in patients with colorectal cancer and liver metastasis by promoting cell proliferation and cancer stem cell‐like properties.

Abstract
BACKGROUND Extramammary Paget's disease (EMPD) is a rare malignant skin cancer. One of the hallmarks of cancers, including EMPD, is an enhancement of aerobic glycolysis, which is also known as the Warburg effect. In the last step of glycolysis, the enzyme lactate dehydrogenase A (LDHA) catalyzes the conversion of pyruvate to lactic acid, the accumulation of which contributes to the creation of an acidic tumour microenvironment. This in turn results in immunosuppression in various types of cancers. However, the contribution of these pathways has not been well-studied in EMPD. OBJECTIVE To investigate the significance of the Warburg effect and its contribution to the tumour immune microenvironment in EMPD. METHODS The mRNA expression levels of molecules involved in glycolysis and immune-related cytokines were examined by ddPCR. The number of immune cells was assessed by immunohistochemistry (IHC). RESULTS The levels of two glycolytic enzymes, HK2 and LDHA, in tumour tissues were significantly increased compared to those in paired-normal tissues. IHC analyses revealed increased numbers of PD-L1+ , PD-1+ , CD163+ M2 macrophages, Iba1+ macrophages and Foxp3+ Tregs that were associated with high LDHA levels in EMPD. ddPCR demonstrated that multiple cytokines including IL-4, IL-6, IL-10, TGF-β and CCL-2 were upregulated and associated with high LDHA levels in EMPD. Statistical analyses showed that IL-6 mRNA expression correlated with the number of CD163+ , Iba-1+ and Foxp3+ cells. CONCLUSION The Warburg effect contributes to immunomodulation in the tumour microenvironment and further elucidation may lead to better understanding of the pathogenesis of EMPD.

Abstract
BACKGROUND Laparoscopic transverse colectomy is technically difficult. In mini-laparotomy surgery, colectomy for midtransverse colon cancer can easily be performed, but exact D2 lymph node dissection is very difficult for a variety of vessels in the transverse colon. Using 3D-CT imaging, we present a case of D2 lymph node dissection where mini-laparotomy transverse colectomy was performedby a small incision similar to that usedin laparoscopic surgery. METHOD The patient was a 60-yearoldwoman with early transverse colon cancer, which was locatedin the mid-transverse colon. Surgical treatment was plannedfor pT1b(1.5mm)andpVM1 in pathological findings after EMR. Using CT colonography(CTC), the location of the primary tumor was identified. Using simulation CTC(sCTC), composedof CTC and 3D imaging of the arteries andveins, the dominant artery was identified and D2 lymph node dissection was simulated. In addition, body surface 3D imaging and permeable surface 3D imaging of the abdominal trunk were performed. Using body surface 3D-sCTC, composedof sCTC and body surface 3D imaging, the minimum incision to enable D2 lymph node dissection was simulated. RESULT Using sCTC, it was identified that the dominant artery was the right branch of the middle colic artery(MCA Rt)andthe accompanying vein was branchedfrom the gastrocolic trunk(GCT). D2 lymph node dissection to separate the branching root of MCA Rt and the accompanying vein was simulated. Next, surgical incision was simulated using body surface 3D-sCTC. Because the branching roots of MCA Rt andGCT were locatedabout 5 cm cranial from the upper rim of the navel, a 7 cm upper abdominal midline incision was designed in addition to a 2 cm umbilical incision. Mini-laparotomy transverse colectomy with a 7 cm incision was performedin accordance with the simulation. The operation time was 2 hours and5 1 minutes, andbloodloss was due to occult bleeding. The patient was discharged 7 days after surgery without complications, and the final diagnosis was pT1bN0M0, StageⅠwith no recurrence for 4 years and2 months after surgery. The cranial incision from the upper rim of the navel has shrank about 3 cm, and the umbilical incision is not noticeable. CONCLUSION D2 lymph node dissection of minilaparotomy transverse colectomy can be a treatment option for early transverse colon cancer through using body surface 3DsCTC.

Preoperative chemoradiotherapy using S-1 combined with celecoxib for advanced lower rectal cancer: Phase I/II study. JOURNAL OF THE ANUS RECTUM AND COLON 2019; 3:43-48. [PMID: 31559366 PMCID: PMC6752131 DOI: 10.23922/jarc.2018-026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Accepted: 10/15/2018] [Indexed: 11/30/2022]
Abstract
OBJECTIVES To clarify the safety and efficacy of celecoxib combined with chemoradiotherapy using S-1 for lower rectal cancer. METHODS Twenty-one patients with pathologically proven lower rectal adenocarcinoma (cT3-T4, Tx N+, M0) were included in this study. A total dose of 45 Gy was administered in daily fractions of 1.8 Gy. Celecoxib was given orally twice daily with S-1 on the day of irradiation. The dose of celecoxib was set at 400 mg/day. In Phase I, the S-1 dose was started at 80 mg/m2/day; in Phase II, S-1 was administered in the same dose as Phase I. Patients underwent surgery six to eight weeks after completing chemoradiotherapy, followed by six months of postoperative adjuvant chemotherapy. RESULTS The S-1 recommended dose was 80 mg/m2/day. The pathological complete remission rate was 15.8%, the rate of protocol completion was 14.3%, and the rate of adverse events exceeding Grade 3 was 19.0%. Surgery was performed in 19 cases, with a sphincter-sparing rate of 31.6%. Postoperative complications exceeding Grade 3 occurred in 52.4% of cases. The three year overall survival and relapse-free survival rates were 89.3% and 67.0%, respectively. CONCLUSIONS We failed to show a synergistic or additive therapeutic effect of preoperative CRT using S-1, combined with celecoxib, for lower advanced rectal cancer beyond CRT using 5 FU or capecitabine alone. The incidence of complications, evidently involving intestinal ischemia, was relatively high. This treatment strategy is not recommended at present.

A randomized controlled, open-label early phase II trial comparing incidence of FOLFIRI.3-induced diarrhoea between Hangeshashinto and oral alkalization in Japanese patients with colorectal cancer. J Clin Pharm Ther 2019; 44:946-951. [PMID: 31407827 DOI: 10.1111/jcpt.13020] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 05/15/2019] [Accepted: 07/17/2019] [Indexed: 11/28/2022]
Abstract
WHAT IS KNOWN AND OBJECTIVE We conducted a pilot clinical trial to investigate whether Hangeshashinto (TJ-14) could be substituted for oral alkalization in patients scheduled to undergo chemotherapy by FOLFIRI.3 regimen for colorectal cancer (CRC). METHODS Patients with CRC were randomized 1:1 to a TJ-14 (7.5 g/day) group or an oral alkalization (sodium bicarbonate, 1.8 g/day; ursodeoxycholic acid, 300 mg/day) group. The primary endpoint was incident of late-onset diarrhoea. A total of 30 patients were randomized to either the TJ-14 group or the alkalization group. RESULTS AND DISCUSSION There was no statistical difference in age, concomitantly used drugs or UGT1A1 genotypes between the groups. In the alkalization group (n = 15), the frequency of grade 0/1/2 and grade 3 diarrhoea was 73% and 27%, respectively. In the TJ-14 group (n = 14), the frequency of grade 0/1/2 and grade 3 diarrhoea was 79% and 21%, respectively. Grade 4 diarrhoea was not observed in either group. There was no statistically significant difference in other adverse events or in response to FOLFIRI.3 between the groups. WHAT IS NEW AND CONCLUSION This pilot trial suggests that TJ-14 is a promising alternative treatment option to reduce FOLFIRI.3-induced late-onset diarrhoea, although additional clinical study with a larger number of patients is necessary to confirm these results.

Abstract
We experienced a young woman with congestive heart failure (CHF) caused by renovascular hypertension (RVH) and subsequent hypertensive heart disease. She underwent tumor resection and intraoperative radiation therapy because of neuroblastoma at age 2. She was diagnosed with RVH and hypertensive heart disease due to radiation-induced renal artery stenosis at age 12. Thereafter, she was hospitalized with CHF caused by uncontrolled RVH at age 19, and renal autotransplantation with extraction of left kidney was performed after the recovery of CHF. Her blood pressure has been well controlled without CHF readmission during four years of follow-up after the operation.

Abstract
BACKGROUND Callithrix jacchus, generally known as the common marmoset, has recently garnered interest as an experimental primate model for better understanding the basis of human social behavior, architecture and function. Modelling human neurological and psychological diseases in marmosets can enhance the knowledge obtained from rodent research for future pre-clinical studies. Hence, comprehensive and quantitative assessments of marmoset behaviors are crucial. However, systems for monitoring and analyzing marmoset behaviors have yet to be established. NEW METHOD In this paper, we present a novel multimodal system, MarmoDetector, for the automated 3D analysis of marmoset behavior under freely moving conditions. MarmoDetector allows the quantitative assessment of marmoset behaviors using computerised tracking analysis techniques that are based on a Kinect system equipped with video recordings, infrared images and depth analysis. RESULTS Using MarmoDetector, we assessed behavioral circadian rhythms continuously over several days in home cages. In addition, MarmoDetector detected acute, transient complex behaviors of alcohol injected marmosets. COMPARISON TO EXISTING METHOD Compared to 2D recording, MarmoDetector detects activities more precisely and is very sensitive as we could detect behavioral defects specifically induced by alcohol administration. CONCLUSION MarmoDetector facilitates the rapid and accurate analysis of marmoset behavior and will enhance research on the neural basis of brain disorders.

Abstract
Social relationships are a key determinant of social behaviour, and disruption of social behaviour is a major symptom of several psychiatric disorders. However, few studies have analysed social relationships among multiple individuals in a group or how social relationships within a group influence the behaviour of members with impaired socialisation. Here, we developed a video-analysis-based system, the Multiple-Animal Positioning System (MAPS), to automatically and separately analyse the social behaviour of multiple individuals in group housing. Using MAPS, we show that social isolation of male mice during adolescence leads to impaired social proximity in adulthood. The phenotype of these socially isolated mice was partially rescued by cohabitation with group-housed (socially-reared) mice, indicating that both individual behavioural traits and those of cagemates influence social proximity. Furthermore, we demonstrate that low reactive behaviour of other cagemates also influence individual social proximity in male mice. Nozomi Endo, Waka Ujita et al. present a video-based system for analysing social behaviour of groups of mice. They find that male mice reared in isolation have impaired social proximity in adulthood, but this is partially rescued by cohabitation with socially-reared mice.

Abstract
BACKGROUND AND PURPOSE It is reported that simulation computed tomography colonography(S-CTC), which combines CTC and 3-dimensional(3D)vascular imaging, is useful in colorectal cancer surgery. However, it is difficult to create 3D vascular images using non-contrast CT. Laparoscopic transverse colectomy is said to be technically difficult. Mini-laparotomy surgery for mid-transverse colon cancer is quite easy to perform. However, exact D2 lymph node dissection is very difficult. We present a case of D2 lymph node dissection during mini-laparotomy transverse colectomy performed using S-CTC, which involves the creation of 3D vascular images using non-contrast CT. PATIENT AND METHOD The patient was a 77-year-old man with transverse colon cancer located in the mid-transverse colon, cT2N0M0, Stage Ⅰ. He had coexisting chronic renal failure. Non-contrast CT was performed prior to surgery, and the images were processed using workstation Zaiostation2. RESULTS Both the artery and the vein created from non-contrast CT could be visualized clearly until the marginal vessels. Using noncontrast S-CTC in combination with CTC and 3D artery imaging, it was identified that the dominant artery was the left branch of the middle colic artery(MCA Lt), while the right branch of the MCA(MCA Rt)and accessory MCA(AMCA)were 10 cm or more apart. The fusion of 3D artery and vein imaging made it evident that the vein accompanying MCA Lt branched from the superior mesenteric vein. Using non-contrast S-CTC, D2 lymph node dissection, dissection of the branching root of MCA Lt and the vein at the same level was simulated. Thus, mini-laparotomy transverse colectomy was performed through a 7 cm incision, in accordance with the simulation. CONCLUSION Non-contrast S-CTC was useful for performing D2 lymph node dissection during mini-laparotomy transverse colectomy.

Abstract
A 54-year-old man receiving dialysis for diabetic nephropathy underwent surgery for sigmoid cancer. Nine months later, he was diagnosed with multiple liver metastases. He underwent 2 courses of FOLFIRI plus panitumumab(Pmab)as first-line therapy, 15courses of capecitabine plus bevacizumab(Bmab)as second-line therapy, and 27 courses of Pmab as third-line therapy. He developed various complications throughout the disease course, such as heart disease, diabetic gangrene in both legs, and abscess of liver metastasis. The tumor marker levels after each event were higher than the previous event and subsequently decreased with the resumption of chemotherapy. However, after 27 courses of Pmab, his liver and para-aortic lymph node metastases exacerbated, and he ultimately died from a poor general condition at 42 months after the initial recurrence of liver metastasis. Evidence regarding the safety and pharmacokinetics of chemotherapy in dialysis patients is insufficient at present. Herein, we report a case of metastatic colon cancer in a patient on hemodialysis along with a literature review.

Abstract
Genome medicine has been attractingmuch of attention in Japan. The combination of molecular targetingdrug s and somatic mutations has been developed for cancer treatment, which was introduced clinically with evidence by cancer type. Several cancer somatic mutations can be identified in a single test inexpensively using next-generation sequencing(NGS). Drug approval not based on organs but on cancer genome analysis has been practiced mainly in the United States, and is also being implemented in Japan. However, cancer treatment strategies using molecular targeting drugs and the associated diagnosis are limited in each type of cancer. Furthermore, the benefit of NGS, which is an improved and inexpensive technique, is still insignificant in Japan. However, the clinical biobank system was initiated in 2011 to prepare the era of cancer genome medicine in our department. The quality of biological samples was strictly controlled by the standardized sampling procedures, which can be used by the researchers accordingto their convenience. Furthermore, the cooperative research involvingcommercial corporations has been started.

Abstract
Familial adenomatous polyposis (FAP) is an inherited disorder characterized by numerous colorectal adenomatous polyps with predisposition to the development of colorectal cancer (CRC). Here, we conducted genome-wide DNA methylation analysis of FAP neoplasms, including seven cancer samples and 16 adenoma samples, using an Infinium 450K BeadArray. As controls for sporadic colorectal neoplasms and mucosae, we used Infinium 450k data from 297 CRC samples, 45 colorectal adenoma samples, and 37 normal mucosa samples with reference to The Cancer Genome Atlas and other databases. Unsupervised two-way hierarchical clustering analysis of FAP and sporadic CRC/adenoma revealed that CRC was classified into four DNA methylation epigenotypes (MEs): high-ME (HME), intermediate-ME (IME), low-ME (LME), and normal-like ME (NME). Five FAP neoplasms (two cancer and three adenoma) were clustered with IME, whereas 18 FAP neoplasms (five cancer and 13 adenoma) were clustered into NME. IME FAP neoplasms significantly correlated with KRAS mutations, similar to sporadic CRC. Within IME cases, however, aberrant DNA methylation was significantly less frequent in FAP neoplasms than sporadic neoplasms, and these unmethylated genes included WNT family genes and several types of oncogenes. In summary, FAP neoplasms were classified into at least two molecular subtypes, i.e., NME in the majority of cases showing mostly no aberrant methylation and IME in some cases accompanied by KRAS mutations but less frequent aberrant DNA methylation than sporadic neoplasms, suggesting that FAP may follow a tumorigenesis pathway different from that of sporadic CRC.

Abstract
OBJECTIVE This study aimed to use convolutional neural network (CNN), a deep learning software, to assist in cT1b diagnosis. METHODS This retrospective study used 190 colon lesion images from 41 cases of colon endoscopies performed between February 2015 and October 2016. Unenhanced colon endoscopy images (520 × 520 pixels) with white light were used. Images included 14 cTis cases with endoscopic resection and 14 cT1a and 13 cT1b cases with surgical resection. Protruding, flat, and recessed lesions were analyzed. AlexNet and Caffe were used for machine learning. Fine tuning of data to increase image numbers was performed. Oversampling for the training images was conducted to avoid impartiality in image numbers, and learning was carried out. The 3-fold cross-validation method was used. Sensitivity, specificity, accuracy, and area under the curve (AUC) values in the receiver operating characteristic curve were calculated for each group. RESULTS The results were the average of obtained values. With CNN learning, cT1b sensitivity, specificity, and accuracy were 67.5, 89.0, and 81.2%, respectively, and AUC was 0.871. CONCLUSION Quantitative diagnosis is possible using an endoscopic diagnostic support system with machine learning, without relying on the skill and experience of endoscopists. Moreover, this system could be used to objectively evaluate endoscopic diagnoses.
