Abstract
A clinical trial was done by the Group, Japan to evaluate the efficacy of 26,27-F6-1,25(OH)2D3 on the calcium and bone metabolism of 43 uremic patients on hemodialysis, 24 men and 19 women with a mean age of 50.9 +/- 2.1 years. The initial dose administered orally was 0.05 micrograms/day for 2 weeks. Then the dose was increased every 2 weeks by 0.05 micrograms each time until the dose of 0.3 micrograms/day was reached or until serum calcium increased. 26,27-F6(OH)2D3 increased serum calcium levels significantly at a mean dose of 0.08 +/- 0.03 micrograms/day and at 0.05 micrograms/day of dose comparison in hemodialyzed patients. It decreased the serum level of PTH significantly at a mean dose of 0.14 +/- 0.06 micrograms/day and at 0.3 micrograms/day by dose comparison. The serum level of bone Gla protein increased significantly at a mean dose of 0.18 +/- 0.07 micrograms/day and at 0.25 micrograms/day by dose comparison in the same patients. These results suggest that 26,27-F6-1,25(OH)2D3 has a higher potency in calcium mobilization than 1,25(OH)2D3 in uremic patients on hemodialysis.

Abstract
We evaluated the influence of the cancer microenvironment formed by peritoneal invasion (CMPI) on clinical findings in colon cancer patients. In addition to the association with poor prognosis, we discovered a relationship with bowel obstruction. Detailed analysis revealed that clinical findings related to bowel obstruction occurred more frequently in patients with an elevated type tumor, which had peritoneal elastic laminal elevation to the tumor surface, compared to those with non-elevated type tumors among those with elastic laminal invasion (ELI). Lateral tumor spread and increase of tumor annularity rate in ELI-positive elevated type cases suggested the morphological progression from ELI-positive non-elevated type to elevated type. In addition, α-smooth muscle actin expression was the highest in ELI-positive elevated type, and prominent expressions were found not only in the deep tumor area but also in the shallow tumor area. Furthermore, contraction assays revealed the robust contractile ability of subperitoneal fibroblasts stimulated by cancer cell-conditioned medium. Our findings suggest that CMPI spread into the luminal side of the colonic wall along with tumor progression, which caused bowel obstruction through the activation of subperitoneal fibroblasts. However, although the clinical outcome was not different between the two types, the clinical findings were affected by the spread of CMPI. We are the first to explore how the alteration of the tumor-promoting microenvironment, along with tumor progression, contributes to the development of clinical findings.

Abstract
This article evaluates the suitability of cadavers embalmed by the saturated salt solution (SSS) method for surgical skills training (SST). SST courses using cadavers have been performed to advance a surgeon's techniques without any risk to patients. One important factor for improving SST is the suitability of specimens, which depends on the embalming method. In addition, the infectious risk and cost involved in using cadavers are problems that need to be solved. Six cadavers were embalmed by 3 methods: formalin solution, Thiel solution (TS), and SSS methods. Bacterial and fungal culture tests and measurement of ranges of motion were conducted for each cadaver. Fourteen surgeons evaluated the 3 embalming methods and 9 SST instructors (7 trauma surgeons and 2 orthopedists) operated the cadavers by 21 procedures. In addition, ultrasonography, central venous catheterization, and incision with cauterization followed by autosuture stapling were performed in some cadavers. The SSS method had a sufficient antibiotic effect and produced cadavers with flexible joints and a high tissue quality suitable for SST. The surgeons evaluated the cadavers embalmed by the SSS method to be highly equal to those embalmed by the TS method. Ultrasound images were clear in the cadavers embalmed by both the methods. Central venous catheterization could be performed in a cadaver embalmed by the SSS method and then be affirmed by x-ray. Lungs and intestines could be incised with cauterization and autosuture stapling in the cadavers embalmed by TS and SSS methods. Cadavers embalmed by the SSS method are sufficiently useful for SST. This method is simple, carries a low infectious risk, and is relatively of low cost, enabling a wider use of cadavers for SST.

Abstract
BACKGROUND As an anus-preserving surgery for very low rectal cancer, intersphincteric resection (ISR), has advanced markedly over the last 20 years. We investigated long-term oncologic, functional, and quality of life (QOL) outcomes after ISR with or without partial external sphincter resection (PESR). METHODS A series of 199 patients underwent curative ISR with or without PESR between 2000 and 2008, with 49 receiving preoperative chemoradiotherapy (CRT group) and 150 undergoing surgery first (surgery group). Overall survival (OS), disease-free survival (DFS), and local relapse-free survival (LFS) rates were calculated using Kaplan-Meier methods. Functional outcomes were assessed using the Wexner incontinence score. QOL was investigated using the Short-Form 36 questionnaire (SF-36) and modified fecal incontinence quality of life (mFIQL) scale. RESULTS After a median follow-up of 78 months (range 12-164 months), estimated 7-year OS, DFS, and LFS rates were 78, 67, and 80 %, respectively. LFS was better in the CRT group than in the surgery group (p = 0.045). Patients with PESR or positive circumferential resection margins showed significantly worse survival. The median Wexner incontinence score at >5 years was 8 in the surgery group and 10 in the CRT group (p = 0.01). QOL was improved in all physical and mental subscales of the SF-36 at >5 years. Although the mFIQL showed a relatively good score in all groups at >5 years, a significant difference existed between the CRT and surgery groups (p = 0.008). CONCLUSIONS With long-term follow-up, oncologic, functional, and QOL results after ISR appear acceptable, although CRT is associated with disturbance.

Abstract
Hemidesmosomes are cell-to-matrix adhesion complexes anchoring keratinocytes to basement membranes. For the first time, we present a method to prepare a fraction from human cultured cells that are highly enriched in hemidesmosomal proteins. Using DJM-1 cells derived from human squamous cell carcinoma, accumulation of hemidesmosomes was observed when these cells were cultured for more than 10 days in a commercial serum-free medium without supplemental calcium. Electron microscopy demonstrated that numerous electron-dense adhesion structures were present along the basal cell membranes of DJM-1 cells cultured under the aforementioned conditions. After removing cellular materials using an ammonia solution, hemidesmosomal proteins and deposited extracellular matrix were collected and separated by electrophoresis. There were eight major polypeptides, which were determined to be plectin, BP230, BP180, integrin α6 and β4 subunits, and laminin-332 by immunoblotting and mass spectrometry. Therefore, we designated this preparation as a hemidesmosome-rich fraction. This fraction contained laminin-332 exclusively in its unprocessed form, which may account for the promotion of laminin deposition, and minimal amounts of Lutheran blood group protein, a nonhemidesmosomal transmembrane protein. This hemidesmosome-rich fraction would be useful not only for biological research on hemidesmosomes but also for developing a serum test for patients with blistering skin diseases.

Abstract
SUMMARY Once-weekly administration of 56.5 μg teriparatide improved cortical bone parameters and biomechanical parameters at the proximal femur by CT geometry analysis. INTRODUCTION The aim of this study was to evaluate the effects of weekly administration of teriparatide [human PTH (1-34)] on bone geometry, volumetric bone mineral density (vBMD), and parameters of bone strength at the proximal femur which were longitudinally investigated using computed tomography (CT). METHODS The subjects were a subgroup of a recent, randomly assigned, double-blind study (578 subjects) comparing the anti-fracture efficacy of a once-weekly subcutaneous injection of 56.5 μg teriparatide with placebo (TOWER trial). RESULTS Sixty-six ambulatory postmenopausal women with osteoporosis were enrolled at 15 study sites having multi-detector row CT, and included women injected with teriparatide (n = 29, 74.2 ± 5.1 years) or with placebo (n = 37, 74.8 ± 5.3 years). CT data were obtained at baseline and follow-up scans were performed at 48 and 72 weeks. The data were analyzed to obtain cross-sectional densitometric, geometric, and biomechanical parameters including the section modulus (SM) and buckling ratio (BR) of the femoral neck, inter-trochanter, and femoral shaft. We found that once-weekly teriparatide increased cortical thickness/cross-sectional area (CSA) and total area, and improved biomechanical properties (i.e., decreasing BR) at the femoral neck and shaft. Teriparatide did not change the cortical perimeter. CONCLUSIONS Our longitudinal analysis of proximal femur geometry by CT revealed that once-weekly administration of 56.5 μg teriparatide improved cortical bone parameters at the femoral neck and shaft and also improved biomechanical parameters.

Abstract
A hands-free interface has been developed to allow a single surgeon to control a locally operated forceps manipulating robot. It is based on the use of a pressure sensor sheet placed on the floor to measure temporal changes in the center of gravity of the operator's foot, in addition to the applied force. Pattern recognition was carried out during trials with endoscope specialists and students for six different types of foot movements. The specialist patterns were then used to develop an interface for controlling a robot with five degrees of freedom. Using this control interface, it was found that the robot could successfully handle a model organ during simulated surgery.

Abstract
BACKGROUND Anorectal transplantation is a method for patients who have lost their anorectal function or suffer from congenital anorectal dysfunction to recover this function, and this has been investigated in experimental animal models using pigs, dogs, and rats. In this study, we performed an examination of anorectal transplantation in human cadavers to investigate whether this procedure could be performed in patients. METHODS A 77-year-old woman cadaver 1 was used as the donor and a 98-year-old woman cadaver 2 was used as the recipient. Initially, abdominoperineal excision of the anus and rectum (the Miles' operation) was performed on the recipient. Next, an anorectal graft containing the pudendal nerve (PN), pudendal artery (PA), pudendal vein (PV), inferior mesenteric artery (IMA), and inferior mesenteric vein (IMV) was harvested from the donor. The donor graft was transplanted into the recipient by intestinal anastomosis and microneurovascular anastomoses orthotopically. RESULTS The diameters of the PN (right/left), IMA, and IMV were 2.5 mm/2.5 mm, 2.0 mm, and 1.5 mm, respectively, in cadaver 1, and 2.0 mm/2.0 mm, 2.0 mm, and 2.0 mm, respectively, in cadaver 2. The length of the PN, PA, PV, IMA, and IMV in the graft was sufficient to allow proper anastomosis. CONCLUSION This preliminary study indicated that human anorectal transplantation was possible anatomically and technically. We anticipate our study will aid in the potential future application of this procedure to human patients.

Abstract
SUMMARY Increased levels of serum undercarboxylated osteocalcin, which were associated with bone metabolism markers, correlated inversely with indices of glucose metabolism (plasma glucose, hemoglobin A1C, and glycated albumin) in hemodialysis patients with abnormalities of bone metabolism. INTRODUCTION Undercarboxylated osteocalcin (ucOC), a possible marker of bone metabolism and one of the osteoblast-specific secreted proteins, has recently been reported to be associated with glucose metabolism. We tested the hypothesis that ucOC levels are associated with indices of glucose metabolism in chronic hemodialysis patients with abnormalities of bone metabolism. METHODS Serum ucOC, bone alkaline phosphatase (BAP, a bone formation marker), and tartrate-resistant acid phosphatase-5b (TRACP-5b, a bone resorption marker) were measured in 189 maintenance hemodialysis patients (96 diabetics and 93 non-diabetics), and their relationships with glucose metabolism were examined. RESULTS ucOC correlated positively with BAP (ρ = 0.489, p < 0.0001), TRACP-5b (ρ = 0.585, p < 0.0001) and intact parathyroid hormone (iPTH; ρ = 0.621, p < 0.0001). Serum ucOC levels in the diabetic patients were lower than those of non-diabetic patients (p < 0.001), although there were no significant differences in serum BAP or TRACP-5b between diabetic and non-diabetic patients. Serum ucOC correlated negatively with plasma glucose (ρ = -0.303, p < 0.0001), hemoglobin A1C (ρ = -0.214, p < 0.01), and glycated albumin (ρ = -0.271, p < 0.001), although serum BAP or TRACP-5b did not. In multiple linear regression analysis, log [plasma glucose], log [hemoglobin A1C], and log [glycated albumin] were associated significantly with log [ucOC] after adjustment for age, gender, hemodialysis duration, and body mass index but were not associated with log [BAP], log [TRACP-5b], or log [intact PTH]. CONCLUSION Increased levels of serum ucOC, which were associated with bone metabolism markers, were inversely associated with indices of glucose metabolism in hemodialysis patients.

Abstract
BACKGROUND/AIMS Preoperative chemoradiotherapy (CRT) for rectal cancer improves local control, but can also induce severe anal dysfunction after surgery. The goal of the study was to assess the relationship of the therapeutic effect of CRT with anal function and prognosis after intersphincteric resection (ISR). METHODS The subjects were 37 patients with lower rectal cancer who underwent ISR with preoperative CRT. The rectal cancer regression grade (RCRG) was quantified based on histologic features of surgical specimens. The relationships of RCRG with anal function (assessed by questionnaire) and incontinence (Wexner score) were examined at 12 months after surgery. RESULTS The median Wexner scores at 12 months after stoma closure in RCRG1, -2, and -3 cases were 18.0, 7.5, and 4.5, respectively, and anal function differed significantly among these groups (p = 0.001). Four cases had local recurrence, but 5-year local recurrence rates did not differ significantly among the groups. The 5-year disease-free survival rates were 88.9, 50.8, and 50.0% and the 5-year overall survival rates were 100, 77.3, and 66.7% in RCRG1, -2, and -3 cases, respectively, with no significant differences among the groups. CONCLUSION Postoperative anal function is decreased when the effect of preoperative CRT is strong in patients treated with ISR.

Abstract
BACKGROUND Delayed gastric emptying (DGE) is a common complication following left-sided hepatectomy. The goal of this study was to clarify the clinical implications of an omental flap wrapping procedure that includes fixation to the cut surface of the liver to reduce the incidence of DGE after left-sided hepatectomy. METHODS The study included 50 consecutive patients who underwent left-sided hepatectomy between January 2000 and July 2011. Clinicopathologic risk factors for DGE after left-sided hepatectomy were identified using univariate and multivariate models. The incidence of DGE, digestive symptoms, and postoperative complications were compared between two groups: 25 patients treated with the omental flap wrapping and fixation procedure and 25 patients who did not receive such a flap. RESULTS A univariate analysis revealed that a lack of the omental flap, the lymph node clearance, and use of left hemihepatectomy were associated with postoperative DGE. The multivariate analysis indicated that the lack of the omental flap was the only independent significant factor associated with the DGE (odds ratio, 21.23; p = 0.0002). There was a significant difference in the incidence of DGE between the patients with (4 %) and without an omental flap (36 %). The incidence of gastric distension and the use of prokinetic drugs were also significantly lower in patients with an omental flap than in patients without the flap, and patients with an omental flap resumed a solid diet significantly earlier. CONCLUSIONS This retrospective single-center study revealed that it was possible to reduce the incidence of DGE using a procedure involving omental flap wrapping with fixation to the cut surface of the liver after left-sided hepatectomy.

Abstract
A rectoseminal vesicle fistula is a rare complication after a low anterior resection for rectal cancer, usually developing in the outpatient postoperative period with pneumaturia, fever, scrotal swelling or testicular pain. A diagnostic water-soluble contrast enema, cystography and computed tomography reveal a tract from the rectum to the seminal vesicle. Anastomotic leakage is thought to be partially responsible for the formation of such tracts. This report presents three cases of rectoseminal vesicle fistula, and the presumed course of the disease and optimal treatment options are discussed.

Abstract
Colostomy is conventionally the only treatment for anal dysfunction. Recently, a few trials of anorectal transplantation in animals have been published; however, further development of this technique is required. Moreover, it is crucial to perform this research in dogs, which resemble humans in anorectal anatomy and biology. We designed a canine anorectal transplantation model, wherein anorectal autotransplantation was performed by anastomoses of the rectum, inferior mesenteric artery (IMA) and vein, and pudendal nerves. Resting pressure in the anal canal and anal canal pressure fluctuation were measured before and after surgery. Graft pathology was examined three days after surgery. The anal blood supply was compared with that in three beagles using indocyanine green (ICG) fluorescence angiography. The anorectal graft had sufficient arterial blood supply from the IMA; however, the graft's distal end was congested and necrotized. Functional examination demonstrated reduced resting pressure and the appearance of an irregular anal canal pressure wave after surgery. ICG angiography showed that the pudendal arteries provided more blood flow than the IMA to the anal segment. This is the first canine model of preliminary anorectal autotransplantation, and it demonstrates the possibility of establishing a transplantation model in dogs using appropriate vascular anastomoses, thus contributing to the progress of anorectal transplantation.

Abstract
PURPOSE Preoperative chemoradiotherapy (CRT) for rectal cancer is administered to improve local control, but can also induce severe anal dysfunction after surgery, while preoperative chemotherapy that significantly reduces the primary lesion in rectal cancer has recently been developed. The aim of the study was to examine differences in the effects of preoperative CRT and chemotherapy on tissue degeneration of patients with colorectal cancer. METHODS The subjects were 91 patients, including 68 with rectal cancer who underwent internal sphincteric resection with (n = 47, CRT group) or without (n = 21, control group) preoperative CRT, and 23 with colorectal cancer who received preoperative FOLFOX treatment. Peripheral nerve degeneration was evaluated histopathologically using H&E-stained sections, based on karyopyknosis, disparity of the nucleus, denucleation, vacuolar or acidophilic degeneration of the cytoplasm, and adventitial neuronal changes. RESULTS The incidence of neural degeneration was significantly higher in the CRT group than in the control group and FOLFOX group. There were no differences in any items of neural degeneration between the FOLFOX and control groups. CONCLUSION CRT induced marked neural degeneration around the rectal tumor. FOLFOX treatment produced mild neural degeneration similar to that in the control group.

Abstract
SUMMARY Bone mineral density of the 1/3 distal radius, ultra-distal radius, and lumbar spine correlated significantly and negatively with serum adiponectin. There was a significant positive correlation between serum adiponectin and serum NTX. Thus, adiponectin may play a role in mineral and bone disorder in chronic kidney disease stage 5 dialysis (CKD 5D) patients. INTRODUCTION Serum adiponectin, an adipocyte-produced hormone, has been reported to correlate negatively with bone mineral density (BMD) in the general population. However, little is known about the association between adiponectin and BMD in patients with CKD. METHODS BMD of the 1/3 distal and ultra-distal radius, which are enriched with cortical and cancellous bone, respectively, and the lumbar spine was measured by dual X-ray absorptiometry in 114 Japanese male hemodialysis patients (age 61.0 ± 11.1 years; hemodialysis duration 6.6 ± 3.0 years; 43.9% diabetics). Serum total adiponectin, bone formation marker (bone alkaline phosphatase, BAP), and bone resorption marker (cross-linked N-telopeptide of type I collagen (NTX)) were measured. RESULTS The BMD of the 1/3 distal radius, ultra-distal radius, and lumbar spine correlated significantly and negatively with serum adiponectin level (r = -0.229, p = 0.014; r = -0.286, p = 0.002; r = -0.227, p = 0.013, respectively). In multiple linear regression analyses, serum adiponectin was significantly and independently associated with the BMD of the 1/3 distal radius (R(2) = 0.173, p < 0.001) and ultra-distal radius (R(2) = 0.278, p < 0.001) after adjustment of age, hemodialysis duration, body weight, %fat mass, and log [intact PTH], although it was not with the BMD of the lumbar spine. There was a significant positive correlation between serum adiponectin and serum NTX (r = 0.321, p < 0.001), although there was no significant correlation between serum adiponectin and serum BAP. CONCLUSION Increased levels of serum adiponectin were associated with decrease in BMD in male hemodialysis patients. Adiponectin may play a role in mineral and bone disorder, possibly in bone resorption, of patients with CKD 5D.

Abstract
UNLABELLED Monthly minodronate at 30 or 50 mg had similar efficacy as 1 mg daily in terms of change in bone mineral density (BMD) and bone turnover markers with similar safety profiles. This new regimen provides patients with a new option for taking minodronate. INTRODUCTION Minodronate at a daily oral dose of 1 mg has been proven to have antivertebral fracture efficacy. In the present study, the efficacy and safety of oral minodronate at monthly doses of either 30 mg or 50 mg were compared with a daily dose of 1 mg. METHODS A total of 692 patients with involutional osteoporosis were randomized to receive minodronate at either 30 or 50 mg monthly or a daily dose of 1 mg. The primary endpoint was the percent change from baseline in lumbar spine (LS) BMD at 12 months. Total hip BMD, bone turnover markers, serum calcium (Ca), and parathyroid hormone (PTH) levels were also evaluated. RESULTS Minodronate at monthly doses of 30 or 50 mg were noninferior to the 1 mg daily dose in terms of change in LS-BMD. Changes in total hip BMD were also comparable. Although a transient decrease in serum Ca and increase in PTH levels were observed in all three groups at slightly different magnitudes and time courses, changes in bone turnover markers were comparable among the different dosage groups with a similar time course. Safety profiles were also comparable. CONCLUSION Minodronate at monthly doses of 30 or 50 mg has similar efficacy to the daily 1 mg dose in terms of BMD and bone turnover markers with similar tolerability.

Abstract
BACKGROUND The purpose of the study was to evaluate the feasibility and efficacy of laparoscopic palliative resection in patients with incurable stage IV colorectal cancer. METHODS We reviewed 100 patients with incurable stage IV colorectal cancer who underwent palliative resection of the primary tumor between 2002 and 2009 at National Cancer Center Hospital East (NCCHE). Outcomes and postoperative course were compared between patients who underwent open and laparoscopic surgery. RESULTS Of the 100 patients, 22 were treated with a laparoscopic procedure and 78 underwent an open surgical procedure. There was no difference in the preoperative characteristics of the two groups. In the laparoscopic group, the mean operation time was significantly longer (177 vs. 148 min, p = 0.007) and the amount of blood loss was significantly lower (166 vs. 361 ml, p = 0.002). Postoperative complications occurred in 5 patients (22.7 %) after laparoscopic surgery and in 21 patients (26.9 %) after open surgery, with no significant difference between the two groups. Time to flatus, time to start of food intake, and hospital stay were all shorter after laparoscopic surgery (3.0 vs. 3.8 days, p = 0.003; 3.6 vs. 5.0 days, p < 0.001; and 12.0 vs. 15.0 days, p = 0.005; respectively). Significantly more patients in the laparoscopic group had >15 % lymphocytes on postoperative day 7 (p = 0.049). Overall survival rates were 73.7 and 75.5 % at 1 year after laparoscopic surgery and open surgery, respectively (p = 0.344). CONCLUSIONS A laparoscopic procedure should be considered for palliative resection of the primary tumor for incurable stage IV colorectal cancer, because the results of this study indicate that the procedure is safe and effective.

Abstract
Abstract
Background The steroidal irreversible aromatase inhibitor (AI) exemestane (E), the non-steroidal reversible AI anastrozole (A) and tamoxifen (T) are approved for the first-line treatment of the postmenopausal women with hormone receptor (HR) positive advanced breast cancer (ABC) in Japan. Although there are some studies which compare the efficacy and safety of AIs and T in the first-line disease setting, the number of studies that compare efficacy and safety of AIs is limited. We conducted this multicenter, randomized, double-blinded non-inferiority study, to evaluate the time to progression (TTP) in HR positive ABC randomized to therapy with E or A.
Methods Patients (pts) who were ≥20 years [yrs], postmenopausal, ECOG PS ≤1 and had HR positive ABC that recurred after the adjuvant therapy or metastatic disease settings were eligible and randomized (1:1) to 25 mg/day of E or to 1 mg/day of A. Data were evaluated for non-inferiority of E compared to A defined as the upper limit of a two-sided 95% confidence interval (CI) of the hazard ratio (HR) of TTP being less than or equal to 1.25. The primary endpoint was TTP assessed by the independent radiological images review committee (RIRC). Secondary endpoints included TTP by investigator, time to treatment failure, overall survival (OS), objective response rate (ORR), clinical benefit rate, and safety.
Results A total of 298 pts from 58 sites were randomized to E (n=149; mean age: 63.4 yrs) or A (n=149; mean age: 64.0 yrs). The mean BMI for the E and A arms were 23.0 kg/m2 and 23.6 kg/m2, respectively. Six pts (2 pts in E arm, 4 pts in A arm) were excluded from the full analysis set due to lack of evaluation for anti-tumor response after study medication started.
Median TTP (as per RIRC) was 13.8 months (M) vs. 11.1 M for E vs. A, respectively (HR 1.007; 95% CI: 0.771−1.317). Median TTP (Investigator) was 13.8 M vs. 13.7 M for E vs. A, respectively (HR 1.059; 95% CI: 0.816−1.374). The median OS for A treated pts was 60.1 M, OS for E was not reached (as of data cut-off: December 8, 2010). ORR for E was 43.9% (95% CI: 35.3−52.8) and 39.1% (95% CI: 30.6−18.1) for A. Other analyses, including sub-population analyses are ongoing.
The incidence of treatment related adverse events (AEs) in E arm was 71.1% (n=106) and in A arm 59.7% (n=89); the AEs were mostly grade 1 and 2 in 61.7% (n=92) and 53.7% (n=80) of pts respectively. They were expected and manageable. Treatment related SAEs were similar in both groups: 6 (4.0%) in E arm and 5 (3.4%) in A arm. The most common AEs for E were hot flushes (22.1%), arthralgias (16.8%), musculoskeletal stiffness (11.4%) and γ-GTP increased (10.1%); in A arm, hot flushes (14.8%) and arthralgia (16.8%) were observed in >10% pts.
Conclusions Although median TTP (RIRC) of E is slightly improved compared with that of A, the result of TTP did not meet the non-inferiority criteria. There were no significant differences found between E and A in ORR. Although AEs in E were numerically higher, the observed AE profiles were similar to those previously reported for E and A. This study shows that E is comparable to A in efficacy and safety.

Abstract
PURPOSE To investigate the treatment and outcomes in a series of seven cases of small bowel metastases from lung cancer. METHODS A total of 4114 patients with lung cancer were referred to this institution from 1995 to 2005. Seven (0.17%) developed symptomatic small bowel metastasis and were treated surgically. The clinical, radiological, and pathological records were reviewed. RESULTS Small bowel metastases were diagnosed from 0 to 31 months (mean 11.5 months) after the diagnosis of lung cancer. The clinical symptoms at presentation were acute peritonitis in two patients and abdominal pain in five. Small bowel metastasis was suspected on abdominal X-ray in three cases, computed tomography in two, small bowel radiography in one, and endogastroduodenoscopy in one. All patients underwent surgery and there were no perioperative deaths. Intestinal resection was performed in five cases and a bypass in two. A small bowel metastasis was found in the ileum in four patients. The mean survival period was 7.7 months after surgery. One patient lived for 22 months after bowel resection. Oral intake was possible 1 month after surgery in six cases. CONCLUSION Surgical management should be considered as palliative treatment in patients with a bowel obstruction or peritonitis caused by primary lung cancer.

Abstract
BACKGROUND Intralesional or systemic steroid administration is a promising strategy for the prevention of esophageal stricture after endoscopic therapy. The aim of this study was to evaluate the influence of steroid therapy on the process of healing of defects in the esophageal mucosa after endoscopic mucosal resection (EMR). METHODS Nine beagle dogs were divided into three equal groups: group A, intralesional injection (n = 3), group B, peroral administration (n = 3), and group C, untreated control (n = 3). In group A, triamcinolone acetonide 1 ml (10 mg) was injected directly into the exposed submucosal layer immediately after EMR, and again on postoperative day (POD) 7. In group B, dogs were administered prednisolone 0.5 mg/kg/day orally for 14 days after EMR. In group C, 1 ml normal saline was injected by the same method as that used for group A. On POD 28, histological examination was performed to evaluate epithelialization, inflammation, angiogenesis, and atrophy of the muscularis propria. RESULTS In groups A, B, and C, the mean ulcer area was 50.1, 22.7, and 7.4 mm(2), respectively. The difference between groups A and C was significant (p < 0.01). Inflammatory cells were significantly more evident in the lesions of group A than in those of group C (p < 0.05). In all groups, atrophy of the muscularis propria was evident. However, transmural destruction and fibrosis were observed only in group A. CONCLUSION It was speculated that the esophageal ulcer causes the fibrosis of the submucosa and atrophy of the muscularis propria during process of healing. Intralesional steroid injection deepened the esophageal ulcers and delayed epithelialization, whereas systemic administration did not clearly improve the lesion healing process.
