Abstract
Magnification endoscopy enables in vivo evaluation of gastrointestinal mucosa. Furthermore, endocytoscopy (ECS) with ultra-high magnification enables in vivo observation of cellular atypia during routine endoscopic examination. The purpose of this study is to clarify the efficacy of ECS and endocytoscopic atypia (ECA) classification in various types of benign and malignant pathology in the esophagus. Consecutive 110 patients, who underwent ECS in our institution from March 2003 to December 2009, were included in this study. One hundred and forty-six esophageal lesions were classified according to ECA classification, and these endocytoscopic images were compared with histological images. We categorized endocytoscopic images into five categories according to size and uniformity of nuclei, number of cells and regularity of cellular arrangement. Eighty-one out of 89 ECA-1 to ECA-3 lesions (91.0%) corresponded to Vienna categories 1 to 3. Seventy-one out of 84 ECA-4 or ECA-5 lesions (91.2%) corresponded to Vienna category 4 or 5. Overall accuracy of ECS was 91.3%, providing images similar to conventional hematoxylin and eosin staining. In addition, with ECS, we can take an 'optical biopsy' even in patients with cardiovascular disease without interrupting anticoagulant therapy. A newly designed single charge-coupled device endocytoscope allows observation of target tissue noninvasibly from regular magnification to ultra-high magnification. The development of ECS has opened the door to in vivo cellular imaging, enabling endoscopic diagnosis of tissue cytological atypia during routine endoscopic examination.

Abstract
Abstract
Background: No studies have yet clarified the mechanism of acquired resistance to insulin-like growth factor-1 receptor (IGF-1R) tyrosine kinase inhibitor (TKI). Our previous study of 16 breast cancer cell lines found that only MCF-7 expressed high levels of insulin receptor substrate (IRS)-1 and was sensitive to the IGF-1R-TKI NVP-AEW541.
Material and Methods: We developed a model of acquired resistance to NVP-AEW541 by continuously exposing MCF-7 cells to NVP-AEW541, naming the model MCF-7-NR. To explore the mechanism of acquired resistance to NVP-AEW541, the effects of NVP-AEW541 on cell growth and IGF-1R signaling in MCF-7 and MCF-7-NR cells were examined.
Results: With Western blot analysis, we found that MCF-7-NR had much lower levels of IRS-1 than parental MCF-7. While phosphorylation of Akt was completely inhibited by administration of NVP-AEW541 (3 μM) in both cell lines, phosphorylation of S6K remained high only in MCF-7-NR. The notion of Akt-independent S6K phosphorylation in MCF-7-NR was further supported by the fact that cell growth and phosphorylation of S6K was affected by administration of the Akt inhibitor perifosine to a lesser degree in MCF-7-NR than in MCF-7. Further, the mTOR inhibitor everolimus inhibited phosphorylation of S6K and cell growth equally in both lines. Screening of MCF-7 and MCF-7-NR lines for phosphorylation of 42 receptor tyrosine kinases with and without 3μM NVP-AEW541 showed that Tyro3 phosphorylation remained high only in MCF-7-NR cells. Gene silencing of Tyro3 using siRNA resulted in reduced cell growth, decreased phosphorylation of phosphoinositide-dependent kinase-1 (PDK-1) and protein kinase C α/βII, reduced expression of cyclin D1 in the MCF-7-NR line, with minimal effects evident in the MCF-7 line.
Discussion: Findings from our current study support the possibility of predicting sensitivity to NVP-AEW541 by measuring IRS-1 expression, as hypothesized in our previous study. Akt-independent activation of mTOR/S6K by an as-yet-undefined mechanism appears to induce acquired resistance to NVP-AEW541, and as such mTOR inhibitors may have therapeutic value. Tyro3 upregulation and migration of control of cellular growth and cyclin D1 expression may also induce resistance to NVP-AEW541. Although the validity of these findings should be evaluated in further preclinical studies and eventually in clinical trials, our observations may lead to individualized use of NVP-AEW541 and the development of “backup drugs” against tumors that acquire resistance to NVP-AEW541.

Abstract
OBJECTIVE The aim of this study is to evaluate the influence of antenatal magnesium sulfate (MgSO(4)) treatment on the clinical responsiveness of the ductus arteriosus to indomethacin prophylaxis and on that of symptomatic patent ductus arteriosus (sPDA) to indomethacin treatment in premature neonates. STUDY DESIGN This is a retrospective study of 160 consecutively admitted neonates with a gestational age of <28 weeks (41 MgSO(4) exposed and 119 controls) who received indomethacin prophylaxis. RESULT Incidence of early closure of the ductus arteriosus was lower in the MgSO(4)-exposed neonates than in the control group (59 vs 84%, respectively; P=0.002), whereas incidence of an sPDA was higher (46 vs 24%, respectively; P=0.006). Response to indomethacin treatment was similar between the two groups. Logistic regression analysis indicated increased risk of failure of early ductus arteriosus closure following antenatal MgSO(4) treatment (odds ratio, 4.03; P=0.002). CONCLUSION In extremely preterm neonates, antenatal MgSO(4) treatment reduces clinical responsiveness of the ductus arteriosus to indomethacin prophylaxis but not that of sPDA to indomethacin treatment.

Abstract
BACKGROUND AND STUDY AIMS Carbon dioxide (CO (2)) insufflation for endoscopy has been reported to provide superior recovery and is expected to reduce the risk of serious complications, including air embolism and tension pneumothorax, whereas general anesthesia offers some advantages not found under intravenous sedation. Little is known about the effect of prolonged CO (2) insufflation into gastrointestinal tracts on arterial CO (2) tension (PaCO (2)). Here we introduce the use of general anesthesia with CO (2) insufflation for esophagogastroduodenal endoscopic submucosal dissection (ESD). PATIENTS AND METHODS A prospective observational study was conducted in a university-affiliated hospital. A total of 100 patients were scheduled for esophagogastroduodenal ESD under general anesthesia with CO (2) insufflation, using standardized anesthesia techniques and unchanged ventilatory settings. Arterial blood gas analyses were repeated at predetermined time intervals. RESULTS Of the initial 100 participants, 94 patients undergoing ESD and four patients undergoing endoscopic mucosal resection completed the study. The median procedure time was 122 minutes (range 29 - 309 minutes). The median baseline PaCO (2) of 28 mmHg increased to a median peak PaCO (2) of 39 mmHg ( P < 0.001), with marked inter-individual variability in the time courses of changes in PaCO (2). The correlation coefficient of PaCO (2) with the procedure time was low (r = 0.194; n = 577, P < 0.0001). FEV (1.0) % (forced expiratory volume in 1 second/forced vital capacity) of < 70 % and esophagoscopy vs. gastroduodenoscopy were relative enhancement factors of PaCO (2). CONCLUSION Increases of PaCO (2) during esophagogastroduodenal ESD under general anesthesia with CO (2) insufflation remained within acceptable or readily controllable ranges, and are little enhanced by prolongation of the procedure. Esophagogastroduodenal ESD can be performed safely and feasibly with this procedure.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) was developed by our group to provide a less invasive permanent treatment for esophageal achalasia. PATIENTS AND METHODS POEM was performed in 17 consecutive patients with achalasia (10 men, 7 women; mean age 41.4 years). A long submucosal tunnel was created (mean length 12.4 cm), followed by endoscopic myotomy of circular muscle bundles of a mean total length of 8.1 cm (6.1 cm in distal esophagus and 2.0 cm in cardia). Smooth passage of an endoscope through the gastroesophageal junction was confirmed at the end of the procedure. RESULTS In all cases POEM significantly reduced the dysphagia symptom score (from mean 10 to 1.3; P = 0.0003) and the resting lower esophageal sphincter (LES) pressure (from mean 52.4 mmHg to 19.9 mmHg; P = 0.0001). No serious complications related to POEM were encountered. During follow-up (mean 5 months), additional treatment or medication was necessary in only one patient (case 17) who developed reflux esophagitis (Los Angeles classification B); this was well controlled with regular intake of protein pump inhibitors (PPIs). CONCLUSIONS The short-term outcome of POEM for achalasia was excellent; further studies on long-term efficacy and on comparison of POEM with other interventional therapies are awaited.

Abstract
BACKGROUND The mechanism of resistance to human epidermal growth factor receptor 2 (HER2)-targeted agents has not been fully understood. We investigated the influence of PIK3CA mutations on sensitivity to HER2-targeted agents in naturally derived breast cancer cells. MATERIALS AND METHODS We examined the effects of Calbiochem (CL)-387,785, HER2 tyrosine kinase inhibitor, and trastuzumab on cell growth and HER2 signaling in eight breast cancer cell lines showing HER2 amplification and trastuzumab-conditioned BT474 (BT474-TR). RESULTS Four cell lines with PIK3CA mutations (E545K and H1047R) were more resistant to trastuzumab than the remaining four without mutations (mean percentage of control with 10 microg/ml trastuzumab: 58% versus 92%; P = 0.010). While PIK3CA-mutant cells were more resistant to CL-387,785 than PIK3CA-wild-type cells (mean percentage of control with 1 microM CL-387,785: 21% versus 77%; P = 0.001), CL-387,785 retained activity against BT474-TR. Growth inhibition by trastuzumab and CL-387,785 was more closely correlated with changes in phosphorylation of S6K (correlation coefficient, 0.811) than those of HER2, Akt, or ERK1/2. Growth of most HER2-amplified cells was inhibited by LY294002, regardless of PIK3CA genotype. CONCLUSIONS PIK3CA mutations are associated with resistance to HER2-targeted agents. PI3K inhibitors are potentially effective in overcoming trastuzumab resistance caused by PIK3CA mutations. S6K phosphorylation is a possibly useful pharmacodynamic marker in HER2-targeted therapy.

Abstract
Aortocameral fistula is a rare complication of aortic dissection. We herein report a case of aortic dissection after aortic valve replacement (AVR) complicated with a fistula to the left atrium. A 76-year-old man who had undergone AVR 1 year previously, was admitted to our hospital because of facial edema and chest discomfort. On auscultation, a continuous murmur was heard at the left lower sternal border. Computed tomography revealed dissecting aneurysm of the ascending aorta and a fistula to the left atrium was suspected. Transesophageal echocardiography showed the fistula between the false lumen of the aneurysm and the left atrium. Ascending aorta replacement and closure of the fistula was performed. There was dense adhesion between the aortic root and the roof of the left atrium. It seems that postoperative adhesion plays an important role in formation of aortocameral fistula.

Abstract
6021 Background: An oral fluoropyrimidine, S-1, has shown high efficacy against head and neck cancer (HNC), with a response rate of 34%. We investigated the maximum tolerated dose (MTD) of combination therapy with docetaxel, cisplatin and S-1 (TPS) in patients (pts) with locally advanced or recurrent/metastatic HNC. Methods: Eligibility criteria were histologically proven HNC, PS 0–1, age ≤75 years, adequate organ function, and no prior chemotherapy. Treatment consisted of 1-hour infusion of docetaxel at escalating doses of 50, 60 and 70 mg/m2, 2-hour infusion of cisplatin at 70 mg/m2/day on day 1, and S-1 twice daily on days 1–14 at escalating doses of 40, 60, and 80 mg/m2/day. This regimen was repeated every 3 or 4 weeks. Pts with locally advanced HNC received concurrent chemoradiotherapy after completion of 3 cycles of TPS. Results: Forty pts were enrolled, consisting of 33 males and 7 females with a median age of 50 years (range 22–74 years). Twenty-nine cases were locally advanced cancer and 11 were metastatic cancer. 116 cycles (median = 3, range 1–6) were administered in 6 dose levels. Grade 3 or 4 hematological toxicities were neutropenia (59%), febrile neutropenia (13%), and anemia (8%), whereas no grade 3 or 4 thrombocytopenia was seen. Two dose-limiting toxicities (DLTs) were observed at dose level 5 (TPS: 70/70/80 mg/m2/day every 3 weeks), namely one grade 3 infection and one grade 3 hyperbilirubinemia, establishing this as the MTD. Of 12 pts treated at dose level 6 (TPS: 70/70/60 mg/m2/day every 3 weeks), three DLTs were seen, namely one grade 3 diarrhea, one grade 3 ALT/AST and one grade 2 creatinine elevation. Of a total of 40 pts, 6 achieved a complete response and 22 a partial response according to RECIST, giving an overall response rate of 70%. Conclusions: The TPS combination was well tolerated. The recommended phase II dose was determined to be TPS at 70/70/60 mg/m2/day every 3 weeks. Antitumor activity was highly promising, and warrants further investigation. No significant financial relationships to disclose.

Abstract
OBJECTIVE We studied the clinical feature of pulmonary pleomorphic carcinoma. PATIENTS Of 1,073 patients underwent the resection of lung cancer in our hospital, 15 patients (1.4%) had primary pulmonary pleomorphic carcinoma. RESULTS All patients were male, and the age was ranged from 57 to 83, mean 70.3 years old. The mean Brinkman Index was 1,028.7. Thirteen patients underwent the lobectomy with lymph node dissection, 1 patient underwent the bilobectomy with lymph node dissection, and the wedge resection was done for the remaining one. Four patients were in stage IA, 5 were in stage IB, 2 were in stage IIB, 1 was in stage IIIA, 2 were in stage IIIB, and 1 was in stage IV. Histologically, the vascular invasion was showed in 8 of 15 patients. The recurrence was occurred on 9 patients, from 1 to 20 months after surgery. The site of recurrence was lung in 3 patients, brain in 3, and abdominal lymphnodes, subcutaneous soft tissue of shoulder, carcinomatous pleurisy was observed in one patient each. The 1-year survival was 62.5% , and the 3-year survival was 46.9%. Conclusion : The prognosis for pulmonary pleomorphic carcinoma is poor. More meticulous follow up is necessary for patients with pleomorphic carcinoma than those with common non-small cell carcinoma.
