抄録 A 58-year-old Japanese man visited a local clinic for the evaluation of a stomachache. He was diagnosed with intestinal obstruction. His medical history included a proctocolectomy at the age of 38 years, due to familial adenomatous polyposis (FAP). He was referred to our institution, where he underwent a computed tomography examination and endoscopy of the small intestine. The pathological diagnosis was adenocarcinoma. No invasive or metastatic lesions were observed. Therefore, partial resection of the ileum with lymphadenectomy and reconstruction of the ileostomy were performed. Pathological examination revealed that the tumor was type 2, pT3 (SS) , pN1, pPM0, pDM0, pRM0, INFb, ly1, v1, pEX0, PN0. Twenty-nine days after the surgery, the patient was diagnosed with lung metastasis and he underwent lung radiofrequency ablation. We suggest that long-term follow-up is necessary for patients after surgery for FAP, because of the risk of malignant disease developing in other organs.

抄録 An 87-year-old Japanese man underwent percutaneous cryoablation (PCA) therapy for his renal cell tumor. We displaced the colon from the tumor using hydrodissection. Computed tomography (CT) immediately after PCA was indicative of iceball extension to the colon wall, and a discontinuous enhancement of the colon wall was observed. We therefore performed an emergency surgery. On laparotomy, we observed a dark-purple area on the affected area of the colon, and the resected specimen showed focal, deep ulceration on the mucosal surface. Photomicrography revealed mucosal necrosis, submucosal hemorrhage, and necrotic foci in the muscularis propria, corresponding to the discontinuous colon wall enhancement on CT and the deep ulceration and dark-purple area on laparotomy. He recovered from surgery and was discharged without any complications.

抄録 The present single center prospective phase II clinical trial is designed to evaluate the efficacy and safety of percutaneous radiofrequency (RF) ablation for colorectal lung metastases. Patients who have colorectal lung metastases without extrapulmonary metastases are included in this study. The primary endpoint is 3-year overall survival (OS) after RF ablation. The secondary endpoints are the prevalence of adverse events within 4 weeks, local tumor progression rate, 1- and 5-year OS, cause-specific survival, and relapse-free survival. The recruitment of patients commenced in July 2014, and the enrolment of 45 patients is intended over the 3 years of study period.

抄録 The aim of this single-institution, retrospective, observational case-control study was to evaluate the safety and feasibility of laparoscopic proctocolectomy (PC) for ulcerative colitis (UC), by comparing it with a case-control series of open PC. Twenty UC patients who underwent laparoscopic PC were retrospectively compared with the open PC group of 12 patients matched for age, sex, and urgency of the operation. In the laparoscopic PC group, the operative time was significantly longer, but the amount of blood loss was significantly smaller. The open PC patients underwent an intraoperative blood transfusion significantly more often, and the serum C-reactive protein level on the first postoperative day was significantly higher in the open PC group. In the laparoscopic PC group, the rate of severe postoperative morbidities, grades 3 and 4 on the Clavien-Dindo classification, was significantly lower, and the median length of hospital stay was significantly shorter. Laparoscopic PC for patients with UC showed superior perioperative outcomes to open PC, except for longer operative time.

抄録 A case of advanced rectal cancer treated by aggressive local and systemic treatment who has survived more than 7 years from initial recurrence is presented. A 55-year-old woman was diagnosed with advanced lower rectal cancer and underwent a low anterior resection with complete removal of all regional lymph nodes and total mesorectal excision. The tumor was diagnosed as a moderately differentiated adenocarcinoma, pStage IIIB (T3, N2a, M0). Twenty-six months after the initial surgery, local recurrence in the pelvis was detected by computed tomography, and total pelvic exenteration with distal sacrectomy (TPES) was performed after systemic chemotherapy with a molecular-targeted drug. Six months after the TPES, multiple lung metastases were detected. Consequently, the patient underwent radiofrequency ablation (RFA) and chemotherapy. The disease has since been controlled for 38 months. As volume control is essential for cancer treatment, it may be important to combine appropriate local therapy with systemic therapy to metastatic or recurrent sites in order to achieve much longer disease control.

抄録 Secreted frizzled-related protein 2, (SFRP2) is a Wnt inhibitor whose promoter CpGs were recently found to be methylated at high frequency in colorectal cancers (CRCs). We hypothesized that the pattern of SFRP2 methylation may differ throughout the promoter during progressive tumorigenesis. Using combined bisulfite restriction analysis (COBRA), two methylation-sensitive regions (Regions A and B) of the SFRP2 promoter were investigated in 569 specimens of colorectal tissue:222 CRCs, 103 adenomatous polyps (APs), 208 normal colonic mucosa from CRC patients (N-Cs), and 36 normal colonic mucosa from subjects with no evidence of colorectal neoplasia at colonoscopy (N-Ns). Extensive (including both Regions A and B) and partial (either Region A or B) SFRP2 methylation levels were found in 61.7% and 24.8% of CRCs, 8.7% and 37.9% of APs, 3.9% and 39.9% of N-Cs, and 0% and 30.6% of N-Ns, respectively. Extensive methylation of the SFRP2 promoter was present primarily in CRCs, while partial methylation was common in APs. Whereas APs with the KRAS mutant showed no correlation to any pattern of SFRP2 methylation, extensive methylation of the SFRP2 promoter was significantly associated with KRAS mutant CRCs (p<.0001), suggesting that genetic alteration in the RAS-RAF pathway might precede the spread of CpG methylation through the SFRP2 promoter, which is observed in over 60% of advanced colorectal tumors.

抄録 Aberrant promoter methylation, an 'epigenetic' form of genomic instability that leads to transcriptional silencing of tumor suppressor genes, is increasingly being recognized as a crucial component in the evolution of human cancers. With our limited knowledge of the molecular basis and timing of the initiation of altered methylation events in the stepwise progression of cancers, the biggest challenge we currently face is to identify novel biomarkers and technologies for the timely screening of patients carrying such alterations. One such strategy would be to develop tests for the detection of fecal DNA methylation patterns that will improve the sensitivity of noninvasive screening tests for colorectal neoplasia, and moreover, will decrease both mortality and the incremental costs of treating colorectal cancers.
