Abstract
BACKGROUND The standard treatment for anal squamous cell carcinoma is chemoradiation therapy (CRT), but there is a possibility of over-treatment for early-stage disease. cTisN0 and cT1N0 disease is currently indicated for local excision, but it is unclear whether the indication of local excision can be expanded to cT2N0 disease. METHODS 126 patients with cTis-T2N0 anal cancer treated at 47 centers in Japan between 1991 and 2015 were included. Patients were first classified into the CRT group and surgical therapy group according to the initial therapy, and the latter was further divided into local excision (LE) and radical surgery (RS) groups. We compared prognoses among the groups, and analyzed risk factors for recurrence after local excision. RESULTS The CRT group (n = 87) and surgical therapy group (n = 39) showed no difference in relapse-free survival (p = 0.29) and overall survival (p = 0.94). Relapse-free survival curves in the LE (n = 23) and RS groups (n = 16) overlapped for the initial 3 years, but the curve for the LE group went lower beyond (p = 0.33). By contrast, there was no difference in overall survival between the two groups (p = 0.98). In the LE group, the majority of recurrences distributed in locoregional areas, which could be managed by salvage treatments. Muscular invasion was associated with recurrence after local excision (hazard ratio: 22.91, p = 0.011). CONCLUSION LE may be applied to selected patients with anal cancer of cTis-T2N0 stage. Given the high risk of recurrence in cases with muscular invasion, it may be important to consider close surveillance and additional treatment in such patients.

Abstract
PURPOSE One-year mortality is important for referrals to specialist palliative care or advance care planning (ACP). This helps optimize comfort for those who cannot be cured or have a lower life expectancy. Few studies have investigated the risk factors for 1-year mortality after gastrectomy for gastric cancer (GC). METHODS A total of 1415 patients with gastric cancer (stages I-IV) who underwent gastrectomy between 2005 and 2020 were included. The patients were randomly assigned to the investigation group (n = 850) and validation group (n = 565) in a 3:2 ratio. In the investigation group, significant independent prognostic factors for predicting 1-year survival were identified. A scoring system for predicting 1-year mortality was developed which was validated in the validation group. RESULTS Multivariate analysis revealed that the following seven variables were significant independent factors for 1-year survival: age ≧78, preoperative comorbidity, total gastrectomy, postoperative complication (Clavien-Dindo classification CD ≧ 3a), stage III and IV, and R2 resection. While developing a 1-year mortality score (OMS), an age ≧78 was scored 2, preoperative comorbidity, total gastrectomy, and postoperative complication (CD ≧ 3a) were scored 1, and stage III, IV, and R2-resection were scored 2, 3, and 3, respectively. OMS 3 had a sensitivity of 91% and a specificity of 66% for predicting death within 1 year. In the validation group, OMS 5 had a sensitivity of 55% and a specificity of 93% for predicting death within 1 year. CONCLUSIONS OMS may provide important information and help surgeons select the timing of ACP in patients with GC.

Abstract
BACKGROUND During restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis-associated colorectal cancer or dysplasia, ileal pouch-anal handsewn anastomosis (IAA) is preferred to avoid the risk of cancer development in the remaining rectal mucosa. However, there is a risk of the ileal pouch not reaching the anus with this procedure. Here, we created deformable 3-dimensional (3D) models for simulation. METHOD Six patients who underwent IAA without vessel ligation and 5 patients who underwent ileal pouch-anal canal double-stapled anastomosis (IACA) because the ileal pouch did not reach the anus were studied. A 3D printer was used to create deformable 3D models from the data obtained from computed tomography scans. The positional relationship among the mesenteric arteries, pubis, and coccyx were evaluated. RESULT The distance between the superior mesenteric artery root and the tip of the ileal artery was longer in the IAA group than that in the IACA group (IAA vs IACA: 26.2 ± 2.1 cm vs 20.9 ± 1.6cm). The distance from the tip of the ileal artery to the coccyx (IAA vs IACA: 6.7 ± 1.7 cm vs 12.1 ± 2.1 cm) and the distance from the tip of the ileal artery to the lower edge of the pubis (IAA vs IACA; 8.1 ± 1.3 cm vs 12.7 ± 2.4 cm) were longer in the IACA group than those in the IAA group. CONCLUSIONS We established a method for creating 3D deformable models of patients with ileal pouch-anal anastomosis. These 3D models may be useful for preoperative simulation.

Abstract
In Western countries, the gold-standard therapeutic strategy for rectal cancer is preoperative chemoradiotherapy (CRT) following total mesorectal excision (TME), without lateral lymph node dissection (LLND). However, preoperative CRT has recently been reported to be insufficient to control lateral lymph node recurrence in cases of enlarged lateral lymph nodes before CRT, and LLND is considered necessary in such cases. We performed a literature review on aspects of pelvic anatomy associated with rectal surgery and LLND, and then combined this information with our experience and knowledge of pelvic anatomy. In this review, drawing upon research using a 3-dimensional anatomical model and actual operative views, we aimed to clarify the essential anatomy for LLND. The LLND procedure was developed in Asian countries and can now be safely performed in terms of functional preservation. Nonetheless, the longer operative time, hemorrhage, and higher complication rates with TME accompanied by LLND than with TME alone indicate that LLND is still a challenging procedure. Laparoscopic or robotic LLND has been shown to be useful and is widely performed; however, without a sufficient understanding of anatomical landmarks, misrecognition of vessels and nerves often occurs. To perform safe and accurate LLND, understanding the landmarks of LLND is essential.

Abstract
PURPOSE Despite their similar clinical characteristics, appendiceal diverticulitis (AD) and acute appendicitis (AA) are pathologically distinct. This study compared the clinical features of AD and AA and identified relevant risk factors. METHODS Patients who underwent appendectomy with a preoperative diagnosis of either AD or AA were categorized based on histopathological findings. The two groups were compared in terms of various clinical factors. RESULTS Among the 854 patients included in the study, a histopathological evaluation revealed 49 and 805 cases of AD and AA, respectively. A univariate analysis demonstrated that AD was more prevalent than AA among older, taller, and heavier males. A multivariate analysis revealed that male sex, a white blood cell (WBC) count < 13.5 × 103/μL, an eosinophil count ≥ 0.4%, and a mean corpuscular volume (MCV) ≥ 91.6 fL were significant factors differentiating AD from AA. In addition, pathological AD emerged as an independent risk factor for abscess and/or perforation. CONCLUSIONS AD was associated with an older age, robust physique, and significant risk of abscess and/or perforation despite a low WBC count. In addition to imaging modalities, the preoperative factors of male sex, a WBC count < 13.5 × 103/μL, an eosinophil count ≥ 0.4%, and a MCV ≥ 91.6 fL may be useful for distinguishing AD from AA.

Abstract
BACKGROUND Total neoadjuvant therapy (TNT) is a novel treatment strategy that is an alternative to preoperative chemoradiotherapy (CRT) for locally advanced rectal cancer (LARC). However, an optimal protocol for TNT has not yet been established. The present study will be an open-label, single-arm, single-center trial to develop a new protocol. METHODS Thirty LARC patients at high risk of distant metastasis will receive CRT consisting of long-course radiation, concurrent with tegafur/uracil, oral leucovorin, irinotecan (TEGAFIRI), followed by mFOLFOX-6 or CAPOX before undergoing surgery. DISCUSSION Since previous findings showed a high percentage of grade 3-4 adverse events with the TEGAFIRI regimen for CRT and TNT, the primary outcome of this study will be safety and feasibility. Our regimen for CRT consists of the biweekly administration of irinotecan for good patient compliance. The novel combination approach of this treatment may improve the long-term outcomes of LARC.

Abstract
Adenocarcinoma is a common histological type of ulcerative colitis-associated cancer (UCAC), whereas neuroendocrine carcinoma (NEC) is extremely rare. UCAC is generally diagnosed at an advanced stage, even with regular surveillance colonoscopy. A 41-year-old man with a 17-year history of UC began receiving surveillance colonoscopy at the age of 37 years; 2 years later, dysplasia was detected in the sigmoid colon, and he underwent colonoscopy every 3 to 6 months. Approximately 1.5 years thereafter, a flat adenocarcinoma lesion occurred in the rectum. Flat lesions with high-grade dysplasia were found in the sigmoid colon and surrounding area. The patient underwent laparoscopic total proctocolectomy and ileal pouch-anal anastomosis with ileostomy. Adenocarcinoma was diagnosed in the sigmoid colon and NEC in the rectum. One year postoperation, recurrence or metastasis was not evident. Regular surveillance colonoscopy is important in patients with long-term UC. A histological examination of UCAC might demonstrate NEC.

Abstract
A 71-year-old man was diagnosed with advanced non-small cell lung carcinoma and treated with chemotherapy developed ileocecal diverticulitis three times over the last 2 months of receiving second-line treatment. During the fourth diverticulitis event, the patient presented with fever and abdominal pain, worsening after 5 days. Abdominal computed tomography showed ascites and intra-abdominal free air, suggesting bowel perforation with acute diffuse peritonitis. We performed emergency surgery; the surgical findings showed diverticulosis with perforated diverticula in the ileocecal region. We performed ileocecal resection, an ileostomy and a mucous fistula of the ascending colon. Histopathological examinations revealed pseudodiverticula at the perforation, where the mucosa was depressed through the muscularis propria. Hence, we diagnosed perforated ileal diverticulitis. Repeated diverticulitis triggered by chemotherapy might have resulted in perforation. Small bowel diverticula are rare, but diverticulitis can occur in patients receiving chemotherapy and with cases of unexplained fever and abdominal pain.

Abstract
OBJECTIVE This study evaluated the clinical implications of sarcopenia for patients with rectal cancer according to cancer progression. SUMMARY BACKGROUND DATA The negative impact of body composition on long-term outcome has been demonstrated for various malignancies. METHODS We retrospectively reviewed 708 patients with rectal cancer who underwent curative resection at our institution between 2003 and 2020. Factors contributing to long-term outcomes and the incidence of secondary cancer (ISC) were analyzed. Psoas muscle mass index (PMI) was assessed using preoperative computed tomography. Sarcopenia was defined using the PMI cut-off values for Asian adults (6.36 cm2/m2 for males and 3.92 cm2/m2 for females). RESULTS Sarcopenia was identified in 306 patients (43.2%). Sarcopenia was associated with advanced age, low body mass index, smoking history, and advanced T-stage. Multivariate analysis showed sarcopenia was an independent poor prognostic factor for OS (HR 1.71; P = .0102) and cancer-specific survival (HR 1.64; P = .0490). Patients with sarcopenia had significantly higher mortality due to cancer-related death in stages III and IV, whereas non-rectal cancer-related death, including secondary cancer, was markedly increased in stage 0-II sarcopenic rectal patients. Five-year cumulative ISC in patients with and without sarcopenia was 11.8% and 5.9%, respectively. Multivariate analysis revealed that sarcopenia was an independent predictive factor for ISC (HR 2.05; P = .0063). CONCLUSIONS Sarcopenia helps predict survival outcomes and cause of death according to cancer stage for patients with middle/lower rectal cancer who underwent radical surgery. Furthermore, sarcopenia increased the development of secondary cancer in those patients.

Abstract
Colonic metastasis from ovarian cancer is extremely rare, with only seven reported cases. A 77-year-old woman who had previously undergone surgery for ovarian cancer was admitted to a local hospital with anal bleeding. Histopathological analysis confirmed the presence of adenocarcinoma. Colonoscopy revealed a descending colon tumor. The patient was diagnosed with Union for International Cancer Control T3N0M0 descending colon cancer or colon metastasis of the ovarian cancer. Laparoscopic left colectomy was performed; intraoperative frozen section diagnosis confirmed metastasis from ovarian cancer, and the absence of invasion to the serosal surface suggested hematogenous metastasis. This is the first case of colonic metastasis from ovarian cancer that was diagnosed using an intraoperative frozen section and laparoscopically treated.

Abstract
Total mesorectal excision (TME) for rectal cancer is often technically challenging. We aimed to develop a method for three-dimensional (3D) visualization of the TME dissection plane and to evaluate its ability to predict surgical difficulty. Sixty-six patients with lower rectal cancer who underwent robot-assisted surgery were retrospectively analyzed. A 3D TME dissection plane image for each case was reconstructed using Ziostation2. Subsequently, a novel index that reflects accessibility to the deep pelvis during TME, namely, the TME difficulty index, was defined and measured. Representative bony pelvimetry parameters and clinicopathological factors were also analyzed. The operative time for TME was used as an indicator of surgical difficulty. Univariate regression analysis revealed that sex, body mass index, mesorectal fat area, and TME difficulty index were associated with the operative time for TME, whereas bony pelvimetry parameters were not. Multivariate regression analysis found that TME difficulty index (β = - 0.398, P = 0.0025) and mesorectal fat area (β = 0.223, P = 0.045) had significant predictability for the operative time for TME. Compared with conventional bony pelvimetry parameters, the TME difficulty index and mesorectal fat area might be more useful in predicting the difficulty of rectal cancer surgery.

Abstract
An 83-year-old man visited our hospital because of difficulty swallowing. Gastroscopy revealed multiple ulcers and a reddish depression in the lesser curvature of the middle stomach. The initial biopsy showed regenerative atypia, so a gastroscopy was repeated every 3 months thereafter because of suspected malignancy. A biopsy performed 12 months after the initial gastroscopy revealed a well-differentiated adenocarcinoma. After determination of the planned oral resection line by two negative biopsies, laparoscopic distal gastrectomy was performed. The resected specimen showed a 0 - IIa + IIc lesion composed of well-to-moderately differentiated tubular adenocarcinoma, including hand-shaking-type gastric cancer. The oral resection margin was positive due to widespread mucosal extension; therefore, an additional total gastrectomy was needed. Cases of well-differentiated adenocarcinoma and its superficial extension may be difficult to diagnose via endoscopy and biopsy.

Abstract
BACKGROUND Emergency appendectomy is often performed for de Garengeot hernia. However, in some cases, there may be a chance to perform an appendix-preserving elective surgery. CASE DESCRIPTION A 76-year-old woman presented to our hospital with complaints of a right inguinal swelling, which we diagnosed as a de Garengeot hernia using computed tomography (CT). B-mode ultrasonography (US) of the mass showed an appendix 4-6 mm in diameter with a clear wall structure; color Doppler US showed pulsatile blood flow signal in the appendiceal wall. Twenty-eight days later, herniorrhaphy with transabdominal preperitoneal repair (TAPP) was performed without appendectomy. Another 70-year-old woman presented to our hospital with complaints of a painful bulge in the right inguinal region. The diagnosis of de Garengeot hernia was made using CT. B-mode US showed an appendix 5 mm in diameter with a clear wall structure. Color Doppler US showed a pulsatile blood signal in the appendiceal wall. Seven days later, herniorrhaphy with TAPP was performed without appendectomy. CONCLUSION De Garengeot hernia is often associated with appendicitis; however, an appendix-preserving elective herniorrhaphy can be performed if US and intraoperative findings do not suggest appendicitis or circulatory compromise in the appendix.

Abstract
PURPOSE This unicentric, retrospective cohort study aimed to identify the optimal cutoff values of preoperative serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) for the prognosis in patients with stage II/III colon cancer. METHODS After excluding 43 patients with CA19-9 levels < 0.2 U/mL, 588 were included. Receiver operating characteristic curves were constructed to determine the optimal cutoff values of CEA and CA 19-9 for disease relapse. RESULTS The median CEA and CA19-9 values were 3.6 (interquartile range: 2.1-7.2 ng/mL) and 14.3 (interquartile range: 8.1-30.0) U/mL, respectively. The optimal cutoff values of CEA and CA19-9 were 5.4 ng/mL and 22.4 U/mL, respectively. A multivariate analysis of relapse-free survival (RFS) showed that cancer stage, CEA, and CA19-9 were significant independent factors. The RFS of patients with stages II and III colon cancer was significantly stratified by CEA (< 5.4/ ≥ 5.4 ng/mL) and CA19-9 (< 22.4/ ≥ 22.4 U/mL). Prognostication based on the reference values (< 5.0 ng/mL for CEA and < 37.0 U/mL for CA19-9) was less significant than that based on the optimal cutoff values. Both elevated CEA and CA19-9 had no value dependency on RFS: RFS curves were similar between extremely elevated CEA (≥ 54.0 ng/ml) and intermediate CEA (5.4-54.0 ng/ml) and between extremely elevated CA19-9 (≥ 224.0 U/ml) and intermediate CA19-9 (22.4-224.0 U/ml). CONCLUSION The optimal cutoff values of preoperative CEA and CA19-9 for RFS were 5.4 ng/ml and 22.4 U/mL, respectively, in patients with stages II and III colon cancer. Further relapse risk stratification is possible using these values.

Abstract
BACKGROUND De Garengeot hernia, wherein the appendix is present within a femoral hernia, is a rare disease; therefore, the clinicopathological features remain to be clarified. This study aimed to reveal the clinicopathological characteristics of De Garengeot hernia. CASE PRESENTATION Six patients who underwent appendectomy and herniorrhaphy between 1999 and 2018 were included. The incidence of De Garengeot hernia was 3.2% among the 182 femoral hernias that required surgery during the study period. The median age of the patients was 78 years, and five patients were women. The median body mass index was 20.1. Patients frequently had fever or elevated CRP level. Preoperative diagnoses based on computed tomography were femoral (n = 3), inguinal (n = 2), and De Garengeot (n = 1) hernias. Emergency and elective surgeries were performed in four and two patients, respectively. Histopathological examination of the resected appendix showed gangrenous appendicitis (n = 3), perforated appendicitis (n = 2), and appendiceal ischemia (n = 1) in the patients. Postoperatively, one patient developed sepsis. CONCLUSIONS Preoperative diagnosis of De Garengeot hernia is often difficult, and patients frequently have severe appendicitis. Precise diagnosis is required, and emergency surgery should be considered depending on the severity of appendicitis.

Abstract
BACKGROUND Due to prognostic heterogeneity within a stage of gastric cancer (GC), identification of patients with a high risk for recurrence after resection is important. We aimed to identify the prognostic significance of preoperative serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels in patients with Stage I, II, and III GC who underwent R0 gastrectomy. METHODS A total of 794 patients were included in this study after excluding 72 patients with CA19-9 <1.0 U/mL. Receiver operating characteristic curves were drawn to assess the optimal cut-off values of CEA and CA19-9 for disease recurrence. RESULTS The optimal cut-off values of CEA and CA19-9 levels were 2.9 ng/mL and 46.3 U/mL, respectively. Multivariate analysis for relapse-free survival (RFS) showed that stage of GC, CA19-9 levels, postoperative adjuvant chemotherapy, and venous invasion were significant independent factors. The RFS and overall survival (OS) of patients with CA19-9 ≥ 46.3 U/mL were significantly lower than those with CA19-9 < 46.3 U/mL in Stage III GC. However, the RFS of GC patients with CA19-9 ≥ 463 U/mL tended to be better than those with CA19-9 levels between 46.3 and 463 U/mL. CONCLUSIONS The RFS and OS of patients with CA19-9 ≥ 46.3 U/mL were significantly lower than those with CA19-9 < 46.3 U/mL in Stage III GC. However, there was no value dependency of extremely elevated CA19-9 on RFS. Further risk stratification can be obtained by measuring preoperative serum CA19-9 in stage III GC.

Abstract
Patients with intestinal ischemia associated with acute aortic dissection often require emergent bowel resection, which results in serious complications. We present a case of successful surgical management of extensive bowel necrosis caused by acute aortic dissection. A 42-year-old man underwent emergent subtotal resection of the small intestine, right colectomy, tube gastrostomy, and transverse colostomy; however, intestinal continuity was not restored. He developed two major postoperative complications: unconsciousness due to metabolic alkalosis caused by massive discharge from the gastrostomy and jaundice due to bile salt depletion caused by disruption of the enterohepatic circulation. His serum bilirubin levels decreased after the infusion of gastric discharge through gastrostomy into the transverse colon through the colostomy; thereafter, a second operation was performed to restore gastrointestinal continuity. Overall, patients undergoing massive bowel resection without intestinal continuity require careful management of electrolytes and bile salt.

Abstract
PURPOSE Because appendiceal diverticulitis (AD) has a high risk of perforation, precise diagnosis is important for patients with suspected acute appendicitis (AA). In this study, we aimed to reveal the characteristics of computed tomography (CT) images of AD. METHODS CT images were comparatively analyzed in patients who underwent appendectomy and had histopathologically proved AD (n = 23) or AA (n = 365) to reveal specific findings of CT image for AD and determine sensitivity and specificity of CT for AD. RESULTS Univariate analysis showed that maximal diameter of the appendix in AD was significantly smaller than that in AA. Multivariate analysis showed that saccular structure of the appendix wall, cecum or ascending colon diverticulum and peri-appendiceal or -cecal fluid collection were significant independent indicators of AD. Based on that saccular structure of the appendix wall which was the most important specific finding, the sensitivity and specificity of CT for AD were 48% and 99%, respectively. CONCLUSION The saccular structure of the appendix wall, cecum or ascending colon diverticulum and peri-appendiceal or -cecal fluid collection in CT suggest AD in patients with suspected AA. The sensitivity and specificity of CT for diagnosing AD were 48% and 99%, respectively.

Abstract
Background An inguinal hernia is a common disease; however, a malignant tumor within the inguinal hernia sac is rare, and perforated colon cancer in the hernia sac is extremely rare. Case presentation A 73-year-old man presented to our hospital with high fever and painful bulging of the lower abdomen. Computed tomography showed air-containing fluid in the abdominal wall, as well as localized wall thickness of the sigmoid colon in the left groin. An emergency operation revealed a huge subcutaneous abscess and a hard mass of the sigmoid colon within an indirect inguinal hernia sac. Sigmoidectomy and hernia repair using the Marcy method were performed. Lymph node dissection was performed through a transrectal abdominal incision. Histopathological examination of the resected specimen revealed moderately differentiated adenocarcinoma invading the serosal layer with lymph node metastasis. Conclusions Incarcerated inguinal hernia with perforated colon cancer is rare; an emergent operation should accordingly be performed based on infection control, oncological principles, and secure hernia repair.

Abstract
PURPOSE Several studies have analyzed late complications associated with totally implantable venous access ports (TIVAP) implantation via the internal jugular vein (IJV); however, the reported results are inconclusive. The aim of the study is to elucidate the characteristics and risk factors of late complications associated with TIVAP implantation via the IJV. METHODS The study included 482 patients who underwent TIVAP implantation for long-term chemotherapy and/or nutritional support between April 2012 and December 2017. Most patients (95.2%) had malignant diseases. Events requiring TIVAP removal were defined as TIVAP-related complications. RESULTS The median TIVAP and global follow-ups were 319 days (IQR 152-661) and 218,971 catheter days, respectively. The 3-year cumulative TIVAP availability rate was 70%. There were 44 complications (incidence of 9.1%; 0.201 complications/1000 catheter days). Infectious, catheter-related, and port-related complications occurred in 21, 14, and 9 patients, respectively with infectious complications occurring earlier and more frequently than catheter- and port-related complications. Multivariate analysis revealed that age < 65 years and presence of non-gastrointestinal diseases were significant unfavorable factors for TIVAP-related complications. Patients with 1 and 2 of these factors had an elevated risk (2.2 and 5.4 times, respectively) compared with those without. CONCLUSIONS Among the late complications associated with TIVAP implantation via the IJV, infectious complications occur earlier and more frequently than catheter- and port-related complications. Patients with an age < 65 years and having non-gastrointestinal diseases have a significantly high risk of TIVAP-related complications.

Abstract
PURPOSE A growing body of evidence suggests that right-sided colorectal cancer (RCRC) differs from left-sided colorectal cancer (LCRC) in certain clinicopathological features. Therefore, we investigated the difference between RCRC and LCRC in a series of 899 patients. METHODS We reviewed data retrospectively, from 899 patients who underwent R0-resection for stage II and III CRC and compared the clinicopathological factors between patients with RCRC and LCRC. RESULTS The patients with RCRC tended to be older, more likely female, with a larger tumor, higher pathological T stage, and a greater proportion of their tumors were poorly differentiated adenocarcinoma, mucinous adenocarcinoma, or signet ring cell carcinoma than the patients with LCRC,. Recurrence-free survival (RFS) of the patients with RCRC tended to be higher than that of the patients with LCRC and was significantly better among patients with stage II cancer. The overall survival (OS) was similar for patients with RCRC and LCRC, irrespective of cancer stage. CONCLUSION Compared with the patients with LCRC, those with RCRC had several oncologically unfavorable factors, with better RFS in stage II and similar OS in stages II and III. These results suggest that the biological aggressiveness of RCRC is lower than that of LCRC in stage II; however, it can increase after relapse.

Abstract
Exosomes are potent players in the development of metastases and they play an important role in cancer angiogenesis and exacerbation. However, it is unclear how proteins on exosomes affect development of blood vessel networks. In this study, we focused on relationships between membrane proteins on exosomes and angiogenesis using human umbilical vein endothelial cells (HUVEC). Lung tumor cell-derived exosomes induced tube formation and growth of endothelial cells in vitro in a dose-dependent manner involving MAPK activation, but this was not seen in normal lung epithelial cells. Ephrin type-A receptor 2 (EphA2) was identified by proteomic analysis and an inhibition assays showed it is a major MAPK activator on exosomes. Thus EphA2 on exosomes participates in angiogenesis as a ligand of the ephrin signaling pathway. These results support the development of novel therapeutic strategies such as blockade of remote cancer communications through exosomes.

Abstract
Carcinoma ex pleomorphic adenoma is a rare type of cancer of the salivary gland that involves the malignant transformation of a primary or recurrent pleomorphic adenoma, which often metastasises to the lungs or bones, or both. To the best of our knowledge, however, nobody has reported a distant metastasis of this lesion to the brain without such previous metastasis. We report a case in a 64-year-old man.

Abstract
Objectives To identify blood cell markers that predict the long-term outcomes of patients with colorectal cancer. Methods Data from 892 stage II and III colorectal cancer patients who underwent R0 resection were included. We analyzed the correlations of the preoperative blood data, previously reported prognostic indices, and clinicopathologic factors with the long-term outcomes, such as relapse-free survival and overall survival, using univariate and multivariate analyses. Results Multivariate analysis showed that tumor location, stage, mean corpuscular volume, neutrophil-to-lymphocyte ratio, and lymphocyte-to- monocyte ratio were significantly correlated with relapse-free survival. A mean corpuscular volume ≥80.5 fL, neutrophil-to-lymphocyte ratio ≥5.5, and lymphocyte-to- monocyte ratio <3.4 had hazard ratios for disease relapse between 1.39 and 1.93. The cumulative scores of these three factors were aggregated into a laboratory prognostic score, with a maximum score at 6. The relapse-free survival and overall survival were well stratified by a laboratory prognostic score between 0–3 and 4–6, respectively, independent of the stage. Conclusion The mean corpuscular volume, neutrophil-to-lymphocyte ratio, and lymphocyte-to- monocyte ratio can serve as blood cell markers to predict the long-term outcomes of patients who underwent R0 resection for stage II/III colorectal cancer.

Abstract
Splenic cysts are rare and tend to have elevated tumor markers, of which carbohydrate antigen (CA) 19-9 is the most frequently elevated. Therefore, splenic cysts with elevated serum carcinoembryonic antigen (CEA) levels and without CA19-9 elevation are extremely rare. A 26-year-old woman presented with sudden upper abdominal pain while sleeping. Contrast-enhanced computed tomography (CT) showed an 85-mm simple splenic cyst in the upper pole and a moderate amount of ascites around the spleen. The serum levels of CEA, but not CA19-9, were elevated. Spontaneous rupture of a splenic cyst was diagnosed. We performed elective laparoscopic unroofing. The histological findings revealed a stratified squamous epithelium on the inner surface of the cystic wall. On immunohistochemical examination, the squamous epithelium was found to be positive for cytokeratin (CK)7, negative for calretinin, and positive for CEA. The histological diagnosis was an epidermoid cyst. Three months after the operation, the elevated serum tumor marker levels of CEA were normalized. Splenic cysts with high levels of CEA and low levels of CA19-9 are extremely rare. Laparoscopic unroofing is a useful operative procedure for ruptured splenic cysts with elevated levels of serum tumor markers.

Abstract
Nanomaterials are frequently used in microelectronics, cosmetics, and sunscreens. Platinum reagents are commonly used in disease diagnosis, cosmetics, and the food industry. Although research into the development of nanomaterialbased drug delivery systems has yielded promising results, the toxicity of these materials is not fully understood. We investigated the toxicity and drug interactions of 1- and 8-nm diameter platinum nanoparticles (nPt1 and nPt8, respectively) in mice. Acute hepato-renal toxicity of intravenously administered platinum nanoparticles was evaluated biochemically and histologically. Dose-dependent increases in serum markers of hepato-renal function (serum aminotransferases and blood urea nitrogen) were observed following administration of nPt1, whereas nPt8 had no effect, even at 20 mg/kg. Moreover, nPt1 induced interleukin (IL)-6 and IL-1β production 3 and 6 hours after administration. The effect of nPts on drug-induced toxicity was evaluated in mice injected intraperitoneally with carbon tetrachloride or cisplatin, with or without intravenous administration of platinum nanoparticles. All treatments in the absence of nanoparticles were non-lethal and resulted in moderate toxicity. However, exacerbated toxicity was observed in mice injected with carbon tetrachloride or cisplatin together with nPt1, but not in mice co-injected with nPt8. We found that nPt1 cause hepato-renal damage, and the effect is enhanced by chemical inducers of hepatotoxicity and nephrotoxicity. This is the first report demonstrating that nPt1 not only are hepatotoxic and nephrotoxic but also exacerbate drug toxicity. These findings will be useful for future nanotechnology and nanoscience research.

Abstract
Cathepsin K inhibitors are new drugs with the potential for the treatment of osteoporosis because they sustain bony remodelling better than bone resorption inhibitors such as bisphosphonates. The treatment of osteoporosis with inhibitors of bony resorption is associated with osteonecrosis of the jaw, as the deterioration in bony quality that they induce is thought to be one of its causes. The quality of bone is delineated by structural and material characteristics (which include the degree and quality of mineralisation, and depends on the content of proteoglycan and the structural integrity of the bony collagen).1,2 Animal and clinical studies have shown that cathepsin K inhibitors improve the mineral density and structural characteristics of bone, but their effect on the rest remains unknown. We therefore hypothesised that these inhibitors will affect the material characteristics of newly-formed mandibular bone. To verify our hypothesis, we used Raman microspectroscopy to examine such bone in rats that were given a cathepsin K inhibitor, and found unusual crystallinity and an increased substitution of carbonate (CO32-) in its crystal structure.

Abstract
Bone quality is defined by structural and material characteristics. Most studies on the mandible have focused on the analysis of structural characteristics, with insufficient investigation of material characteristics. This study tested whether zoledronate affects the material characteristics of newly formed mandibular bone. Thirty-six female Wistar rats were assigned to three groups: sham-ovariectomized rats (SHAM, n=12), ovariectomized rats (OVX, n=12), and ovariectomized rats treated with zoledronate (ZOL, n=12). The left side of the mandibular ramus of all rats was drilled bicortically. Twenty-eight days after surgery, all surviving rats were euthanized and all mandibles were removed. Raman microspectroscopy was performed, and five spectra per specimen of newly formed mandibular bone were analysed. Compared with OVX rats, the mineral/matrix ratio in ZOL rats was significantly increased (5.43±1.88 vs. 7.86±2.05), while crystallinity (0.055±0.002 vs. 0.050±0.002), relative proteoglycan content (0.43±0.10 vs. 0.31±0.05), and collagen structural integrity (1.16±0.21 vs. 0.72±0.06) were significantly decreased. These changes in material characteristics may explain why rats that received zoledronate exhibited peculiar biological phenomena such as bisphosphonate-related osteonecrosis of the jaw.

Abstract
AKT1 is a cytosolic serine/threonine kinase that is overexpressed in various types of cancer and has a central role in human tumorigenesis. Although it is known that AKT1 is post-translationally modified in various ways including phosphorylation and ubiquitination, methylation has not been reported so far. Here we demonstrate that the protein lysine methyltransferase SMYD3 methylates lysine 14 in the PH domain of AKT1 both in vitro and in vivo. Lysine 14-substituted AKT1 shows significantly lower levels of phosphorylation at threonine 308 than wild-type AKT1, and knockdown of SMYD3 as well as treatment with a SMYD3 inhibitor significantly attenuates this phosphorylation in cancer cells. Furthermore, substitution of lysine 14 diminishes the plasma membrane accumulation of AKT1, and cancer cells overexpressing lysine 14-substiuted AKT1 shows lower growth rate than those overexpressing wild-type AKT1. These results imply that SMYD3-mediated methylation of AKT1 at lysine 14 is essential for AKT1 activation and that SMYD3-mediated AKT1 methylation appears to be a good target for development of anti-cancer therapy.

Abstract
243 Background: We commenced a physician-led clinical trial to examine the efficacy of a combined treatment of peptide vaccine therapy for advanced pancreatic cancer that has no effective treatment. During this trial, there were inquiries from 367 cases, of which 145 cases (40%) were examined at our outpatient clinic. The purpose of this study was to examine these cases in detail and to consider the points to be noted in executing clinical trials for poor prognosis cases. Methods: We examined the timing of inquiry, medical condition, the person(s) they inquired, and other relevant information regarding the 367 subjects who made inquiries. For the 145 cases visited the outpatient clinic of our hospital, we examined their medical condition, treatment and whether or not they have participated in a clinical trial. Results: 140 of the 367 cases (38%) of inquiry were concentrated within the first two months after the start. During these two months, there was a concentration of patients who had completed standard treatments and were a few months into BSC, but were unable to participate in the clinical trial due to deterioration of their general condition. Many of the inquiries were made by family members (spouse or child) of the patients, around twice the number of inquiries made by patients themselves. Even among the 145 subjects that were examined in the outpatient clinic of our hospital, severe cases, in particular, were seen several months after the start of the study. There were many cases that required urgent hospitalization during outpatient visits or patients whose general condition rapidly deteriorated during the screening tests. 23 cases (16%) underwent the clinical trial. Conclusions: In clinical trials such as this one, which handles cases with poor prognosis, many of the subjects are in poor general condition at the inquiry stage, and most of these inquiries are concentrated immediately after the start of the study. Therefore, it is very important to deal with inquiries and make judgments during the outpatient examination on whether or not clinical trial participation is possible.

Abstract
A 62-year-old woman received chemotherapy for breast cancer with bone metastasis and malignant pleural and pericardial effusion. She was examined by imaging for progressive cognitive impairment and headache. Enhanced MRI findings showed multiple solid tumors on brain surface, and brain perfusion scintigraphy showed blood flow decrease in both parietal lobes. She was diagnosed with secondary dementia due to leptomeningeal metastases of breast cancer, and whole brain external irradiation was performed(30 Gy/15 Fr). After treatment, multiple tumors were decreased in size and her cognitive impair- ment was improved.

Abstract
A specific subtype of non-small-cell lung cancer (NSCLC) characterized with an EML4-ALK fusion gene, which drives constitutive oncogenic activation of anaplastic lymphoma kinase (ALK), shows a good clinical response to ALK inhibitors. We have reported multiple examples implying the biological significance of methylation on non-histone proteins including oncogenic kinases in human carcinogenesis. Through the process to search substrates for various methyltransferases using an in vitro methyltransferase assay, we found that a lysine methyltransferase, SET and MYND domain-containing 2 (SMYD2), could methylate lysine residues 1451, 1455, and 1610 in ALK protein. Knockdown of SMYD2 as well as treatment with a SMYD2 inhibitor in two NSCLC cell lines with an EML4-ALK gene significantly attenuated the phosphorylation levels of the EML4-ALK protein. Substitutions of each of these three lysine residues to an alanine partially or almost completely diminished in vitro methylation of ALK. In addition, we found that exogenous introduction of EML4-ALK protein with the substitution of lysine 1610 to an alanine in these two cell lines reduced the phosphorylation levels of AKT, one of the downstream oncogenic molecules in the EML4-ALK pathway, and suppressed the growth of the two cell lines. We further showed that the combination of a SMYD2 inhibitor and an ALK inhibitor additively suppressed the growth of these two NSCLC cells, compared with single-agent treatment. Our results shed light on a novel mechanism that modulates the kinase activity of the ALK fused gene product and imply that SMYD2-mediated ALK methylation might be a promising target for development of a novel class of treatment for tumors with the ALK fused gene.

Abstract
Accumulation of β-catenin in the nucleus is a hallmark of activation of the Wnt/β-catenin signaling pathway, which drives development of a large proportion of human cancers. However, the mechanism of β-catenin nuclear translocation has not been well investigated. Here we report biological significance of SMYD2-mediated lysine 133 (K133) methylation of β-catenin on its nuclear translocation. Knockdown of SMYD2 attenuates the nuclear localization of β-catenin protein in human cancer cells. Consequently, transcriptional levels of well-known Wnt-signaling molecules, cMYC and CCND1, are significantly reduced. Substitution of lysine 133 to alanine in β-catenin almost completely abolishes its nuclear localization. We also demonstrate the K133 methylation is critical for the interaction of β-catenin with FOXM1. Furthermore, after treatment with a SMYD2 inhibitor, significant reduction of nuclear β-catenin and subsequent induction of cancer cell death are observed. Accordingly, our results imply that β-catenin methylation by SMYD2 promotes its nuclear translocation and activation of Wnt signaling.

Abstract
HER2 is a receptor tyrosine kinase, which is amplified and overexpressed in a subset of human cancers including breast and gastric cancers, and is indicated in its involvement in progression of cancer. Although its specific ligand(s) has not been detected, HER2 homodimerization, which is critical for its activation, is considered to be dependent on its expression levels. Here, we demonstrate a significant role of HER2 methylation by protein lysine methyltransferase SMYD3 in HER2 homodimerization. We found that SMYD3 trimethylates HER2 protein at lysine 175. HER2 homodimerization was enhanced in the presence of SMYD3, and substitution of lysine 175 of HER2 with alanine (HER2-K175A) reduced the formation of HER2 homodimers. Furthermore, HER2-K175A revealed lower level of autophosphorylation than wild-type HER2. We also identified that knockdown of SMYD3 attenuated this autophosphorylation in breast cancer cells. Our results imply that SMYD3-mediated methylation of HER2 at Lysine 175 may regulate the formation of HER2 homodimer and subsequent autophosphorylation and suggest that the SMYD3-mediated methylation pathway seems to be a good target for development of novel anti-cancer therapy.
