[A case of colorectal neuroendocrine carcinoma effectively treated with bevacizumab+levofolinate+5-FU chemotherapy].

A 76-year-old woman was admitted to our hospital with diarrhea and weight loss in February 2007. A CT scan revealed a tumor in the abdominal cavity, and although a thorough investigation was conducted, no diagnosis was made. Therefore, she underwent diagnostic surgery in April 2007.

[Adverse events in patients treated with capecitabine as adjuvant chemotherapy after surgery for colorectal cancer--countermeasures against hand-foot syndrome].

Although the 2009 edition of the Guidelines for Colorectal Cancer Therapy recommend capecitabine as a standard postoperative adjuvant chemotherapy for colorectal cancer therapy, a characteristic adverse event, hand-foot syndrome, develops at a high incidence, and appropriate management is necessary to continue therapy. We investigated countermeasures against adverse events, particularly hand-foot syndrome, in patients treated with capecitabine. The subjects were 47 patients aged 64 years (27-84 years) who underwent surgery for colorectal cancer.

[Combination of hepatic arterial infusion therapy and FOLFOX for colorectal cancer with multiple unresectable liver metastases causing severe liver dysfunction].

Purpose: The purpose of this study was to evaluate the efficacy of the combination of hepatic arterial infusion therapy and FOLFOX for colorectal cancer with multiple unresectable liver metastases causing severe liver dysfunction.

Subjects And Methods: The subjects were 13 colorectal cancer patients who had undergone resection of the primary tumor, and showed multiple, unresectable liver metastases and severe liver dysfunction. They consisted of 8 men and 5 women, with a median age of 63(29-77)years.

Randomized, multicenter trial of antibiotic prophylaxis in elective colorectal surgery: single dose vs 3 doses of a second-generation cephalosporin without metronidazole and oral antibiotics.

Hypothesis: Use of prophylactic antibiotics in elective colorectal surgery is essential. Although single-dose prophylactic antibiotics are recommended, the efficacy of single-dose cephalosporin without metronidazole and oral antibiotics is not fully proven. We conducted a multicenter, randomized trial of a single dose vs 3 doses of the second-generation cephalosporin cefmetazole.

[A case of recurrent GIST of the esophagus which completely responded to imatinib mesilate].

Middle and lower esophagectomy was performed in a 68-year-old man in 1997 for the local recurrence of esophageal submucosal tumor after enucleation of the tumor. We subsequently performed partial hepatectomy for multiple liver metastases in 2001. The tumor was first diagnosed as GIST in the histological examinations of the liver metastases.

Chromosomal aberrations detected by comparative genomic hybridization predict outcome in patients with colorectal carcinoma.

To obtain comprehensive information regarding the correlation between genomic changes and clinicopathological parameters such as disease stage, metastases, and survival, we investigated genomic changes by comparative genomic hybridization (CGH) in 73 patients with colorectal cancer (CRC), and assessed the associations of such charges with clinicopathological parameters. Gains of 8q21-22, 13q21-31 and 20q12-qter and loss of 17p12-pter were detected in >50% of stage I tumors. Gain of 8q23-qter and losses of 8p12-pter and 18q12-qter were observed more frequently in stage III/IV tumors than in stage I tumors (all P<0.

Two subtypes of mucinous colorectal carcinoma characterized by laser scanning cytometry and comparative genomic hybridization.

To data, there have been no comprehensive cytogenetic studies of mucinous colorectal carcinomas (MUCs). We used comparative genomic hybridization (CGH) and laser scanning cytometry (LSC), to analyze cytogenetic changes in 21 MUCs and to compare the results with those of our previous study of 60 non-MUCs. Six of 21 MUCs were aneuploid and 15 were diploid.

Characteristics of a hepatozoonosis in lungs of Japanese black bears (Ursus thibetanus japonicus).

In a survey of pathologic agents in the wild animals of central Japan, we found a Hepatozoon sp. in the lungs of Japanese black bears in Fukui, Shiga, and Gifu Prefectures, Japan. Histopathologic examination of organs and tissues from the 18 bears inspected showed hepatozoonosis in all.
