Primary tracheal cancer is a well-known disease while metastases to the trachea from distant sites are exceedingly rare. We report a case of endotracheal metastasis from a colon cancer in a female, who underwent surgery for a sigmoid cancer with no metastases. Five years later, she was diagnosed with a solitary pulmonary metastasis and underwent a left lower lobectomy. After further two years, ...

The purpose of this investigation was to elucidate the enzymic programs of pyrimidine, carbohydrate, and purine me tabolism and the pattern of pyrimidine and purine ribonucleotides in two lines of human colon carcinoma xenografts of different growth rates. The slower-growing colon tumor line was well differentiated; the more rapidly growing line was a poorly differentiated one. The carcinoma xe...

BACKGROUND Metabolic syndrome (MetS) is composed of cardiovascular risk factors including insulin resistance, obesity, dyslipidemia, and hypertension. Most of the components of MetS have been linked to the development of neoplasm. The purpose of this study was to evaluate the relationship between individual components of MetS and colorectal adenoma. METHODS The study subjects were recruited f...

BACKGROUND There is a need for markers in colorectal cancer which will allow subclassification of stage groups into subgroups with high versus low risk of recurrent disease. AIMS To develop monoclonal antibodies that recognise antigens or immature crypt base cells, on the assumption that in a neoplasm undifferentiated but not the terminally differentiated cells will be responsible for tumour ...

BACKGROUND The relationship between type 1 diabetes mellitus (T1DM) and cancer incidence remains unclear. We sought to assess the all-cause and site-specific cancer incidence in patients with T1DM. METHODS A retrospective cohort study design was employed, in which 14 619 patients with T1DM were retrieved from Taiwan's National Health Insurance medical claims between 2000 and 2007. The study s...

In this study, a case of an ingested toothpick partially migrating from the sigmoid colon, causing massive lower gastrointestinal bleeding due to arterial-colic fistula, and stricture of the left ureter is presented. A 70-year-old male was admitted to the emergency department after having feces mixed with fresh and coagulated blood for the past two days. Computed tomography and retrograde urete...

Endoscopic ultrasound-guided cyst drainage is increasingly performed in the treatment of pancreatic pseudocysts and walled-off pancreatic necrosis. We have experienced three cases of colonic fistula after endoscopic ultrasound-guided cyst drainage. Case #1 was a patient with walled-off pancreatic necrosis, in which a fistula into the transverse colon occurred as a late complication of endoscopi...

A 72-year-old woman with advanced ascending colon cancer and an intraductal papillary mucinous neoplasm (IPMN) of the pancreatic head was treated by right hemicolectomy (RHC) and pylorus-preserving pancreaticoduodenectomy (PpPD). Adjuvant chemotherapy was not administered. Multimodal examinations at 5 months after surgery detected a solitary metastatic liver tumor derived from cancer of the asc...
