| 1 | Metastatic bone cancer as a recurrence of early gastric cancer - characteristics and possible mechanisms显示文摘The surgical outcome of most early gastric cancer (EGC)is usually satisfactory. Some cases show bone metastasis even though the depth of cancer invasion is confined to the mucosa. The most frequent site for recurrence of EGC is the liver. Cases of EGC with bone metastasis are reviewed to clarify the clinicopathological characteristics of EGC giving rise to bone metastasis. Possible mechanisms and risk factors underlying this rare condition are proposed.Forty-six cases of bone metastasis from EGC are reviewed from published reports and meeting proceedings in Japan.This investigation suggests that risk factors for bone metastasis from EGC include depressed-type signet-ring cell carcinoma, poorly differentiated carcinoma, and/or the likely involvement of lymph node metastasis, even though the cancer is confined to the gastric mucosa. The risk factors do not include recurrence of EGC in the liver. We speculate that the mechanism of bone metastasis from EGC is via lymphatic channels and systemic circulation. Postoperative follow-up of cases should consider the development of bone metastasis from EGC. We propose the use of elevated alkaline phosphatase levels for the detection of bone metastasis and recommend bone scintigraphy in positive cases. | Michiya Kobayashi Takehiro Okabayashi Takeshi Sano Keijiro Araki | 2005 | World Journal of Gastroenterology2005，11，36： | 9 |

| 6 | Anticancer effect of linalool via cancer-specific hydroxyl radical generation in human colon cancer显示文摘AIM To investigate the anticancer mechanisms of the monoterpenoid alcohol linalool in human colon cancer cells.METHODS The cytotoxic effect of linalool on the human colon cancer cell lines and a human fibroblast cell line was examined using the WST-8 assay. The apoptosisinducing effect of linalool was measured using the terminal deoxynucleotidyl transferase d UTP nickend labeling assay and flow cytometry with Annexin V. Oxidative stress was investigated by staining for diphenyl-1-pyrenylphosphine, which is a cellular lipid peroxidation marker, and electron spin resonance spectroscopy. Sixteen SCID mice xenografted with human cancer cells were randomized into 3 groups for in vivo analysis: control and low-dose and high-dose linalool groups. The control group was administered tap water orally every 3 d. The linalool treatment groups were administered 100 or 200 μg/kg linalool solution orally for the same period. All mice were sacrificed under anesthesia 21 d after tumor inoculation, and tumors and organs were collected for immunohistochemistry using an anti-4-hydroxynonenal antibody. Tumor weights were measured and compared between groups. RESULTS Linalool induced apoptosis of cancer cells in vitro, following the cancer-specific induction of oxidative stress, which was measured based on spontaneous hydroxyl radical production and delayed lipid peroxidation. Mice in the high-dose linalool group exhibited a 55% reduction in mean xenograft tumor weight compared with mice in the control group(P < 0.05). In addition, tumor-specific lipid peroxidation was observed in the in vivo model.CONCLUSION Linalool exhibited an anticancer effect via cancerspecific oxidative stress, and this agent has potential for application in colon cancer therapy. | Kenichi Iwasaki Yun-Wen Zheng Soichiro Murata Hiromu Ito Ken Nakayama Tomohiro Kurokawa Naoki Sano Takeshi Nowatari Myra O Villareal Yumiko N Nagano Hiroko Isoda Hirofumi Matsui Nobuhiro Ohkohchi | 2016 | World Journal of Gastroenterology2016，22，44： | 5 |
| 7 | Size does not determine the grade of malignancy of early invasive colorectal cancer显示文摘AIM:To clarify the clinicopathological characteristics of small and large early invasive colorectal cancers(EI-CRCs),and to determine whether malignancy grade depends on size.METHODS:A total of 583 consecutive EI-CRCs treated by endoscopic mucosal resection or surgery at the National Cancer Center Hospital between 1980 and 2004 were enrolled in this study.Lesions were classified into two groups based on size:small(≤10mm) and large(>10mm).Clinicopathological features,incidence of lymph node metastasis(LNM) and risk factors for LNM,such as depth of invasion,lymphovascular invasion(LVI) and poorly differentiated adenocarcinoma(PDA) were analyzed in all resected specimens.RESULTS:There were 120(21%) small and 463(79%) large lesions.Histopathological analysis of the small lesion group revealed submucosal deep cancer(sm:≥1000 μm) in 90(75%) cases,LVI in 26(22%) cases,and PDA in 12(10%) cases.Similarly,the large lesion group exhibited submucosal deep cancer in 380(82%) cases,LVI in 125(27%) cases,and PDA in 79(17%) cases.The rate of LNM was 11.2% and 12.1% in the small and large lesion groups,respectively.CONCLUSION:Small EI-CRC demonstrated the same aggressiveness and malignant potential as large cancer. | Takahisa Matsuda Yutaka Saito Takahiro Fujii Toshio Uraoka Takeshi Nakajima Nozomu Kobayashi Fabian Emura Akiko Ono Tadakazu Shimoda Hiroaki Ikematsu Kuang-I Fu Yasushi Sano Takahiro Fujimori | 2009 | World Journal of Gastroenterology2009，15，22： | 4 |

| 10 | A unique case of collagenous colitis presenting as protein-losing enteropathy successfully treated with prednisolone显示文摘A 76-year-old woman with a 5-mo history of recurrent diarrhea and generalized edema was admitted to our hospital. Colonoscopy revealed edematous mucosa,and histopathological examination was compatible with collagenous colitis. Protein leakage from the colon,particularly in the ascending portion,was identified on 99mTc-human serum albumin scintigraphy. Collagenous colitis associated with protein-losing enteropathy (PLE) without small bowel disease was diagnosed. Prednisolone treatment ameliorated diarrhea and hypoproteinemia. Collagenous colitis should be included in the differential diagnosis of chronic diarrhea with hypoproteinemia for appropriate management. | Soichi Sano Keiko Yamagami Ayako Tanaka Minako Nishio Tomoyuki Nakamura Yuki Kubo Takeshi Inoue Wataru Ueda Kiyotaka Okawa Katsunobu Yoshioka | 2008 | World Journal of Gastroenterology2008，14，39： | 3 |

| 20 | Isolated ileal perforation due to cytomegalovirus reactivation during management of terbinafine hypersensitivity显示文摘We report a case of 71-year-old man who developed a hypersensitivity syndrome associated with terbinafine. He was placed on terbinafine (250 mg/d) for the treatment of tinea pedis due to diabetes mellitus. Following the treatment with terbinafine, he developed druginduced hypersensitivity syndrome (DIHS). Systemic corticosteroid led to transient improvement of his clinical manifestations. Three months after disease onset, he presented with panperitonitis due to ileal perforation, and underwent an emergency operation. The affected ileum was resected and ileostomy was performed in the terminal ileum. Cytomegalovirus (CMV)-specific IgG antibodies were significantly increased, high-titer CMV antigenemia was detected, and pathological examination of the resected ileum confirmed CMV infection. Based onthese observations, we strongly recommend that physicians monitor reactivation of the family of herpesvirus other than herpesvirus 6, to manage DIHS properly. | Soichi Sano Hiroki Ueno Keiko Yamagami Yosuke Yakushiji Yoshihiro Isaka Isao Kawasaki Masashi Takemura Takeshi Inoue Masayuki Hosoi | 2010 | World Journal of Gastroenterology2010，16，26： | 2 |
