A 79-year-old Hispanic man was admitted to the intensive care unit with symptomatic iron-deficiency anemia and watery diarrhea. Radiological images revealed diffuse colonic wall thickening, a soft-tissue fullness in the ascending colon, and multiple mesenteric lymphadenopathies. Colonoscopy showed multiple aphthous ulcers throughout the colon and a large deep ulcer with irregular raised borders...

Clinically evident metastases of carcinomas to the thyroid gland are rare, particularly from a colorectal primary tumor. We present a case of colonic adenocarcinoma metastatic to the thyroid gland with histopathologic and immunohistochemical findings. A 68-year-old woman with a history of Dukes' stage B colon carcinoma presented a mass in the thyroid gland. The tumor was confirmed to be metasta...

BACKGROUND Increased cellular iron exposure is associated with colorectal cancer (CRC) risk. Hepcidin, a liver peptide hormone, acts as the primary regulator of systemic iron status by blocking iron release from enterocytes into plasma. Concentrations are decreased during low iron status and increased during inflammation. The role of hepcidin and the factors influencing its regulation in CRC re...

Correlation in mortality data between breast cancer and colonic cancer, and increased incidence of colonic cancer in women with breast cancer suggest common factors in their etiology. Similarly protective effect of increasing parity from colonic cancer, and relatively better prognosis in women may imply a common role for sex steroid hormones. In this study clinicopathologic parameters as well a...

Two monoclonal antibodies, YPan1 and YPan2, were produced from spleen cells of mice immunized against a human pancreatic cancer cell line, Capan-2, which also reacted with eight other human pancreatic carcinoma cell lines and with sections of cancerous human pancreas tissue. Reactivity was also found with colonic and stomach carcinoma tissues. Whereas YPan1 reacted strongly with normal pancreat...

Malignant ovarian tumors may represent either primary ovarian cancers or metastatic lesions (from patients with demonstrated primary cancers at other body sites) whose distinction may be difficult using clinical, surgical, and pathological criteria. Monoclonal antibody (MAb) COL-4, reactive with carcinoembryonic antigen, has previously been shown to react preferentially with adenocarcinomas of ...

Colorectal cancer (CRC) is the second highest cause of cancer-related deaths. A successful strategy to improve chemopreventive efficacies is by down-regulating tumor polyamines and enhancing NK cell activities. Colonic carcinogenesis was induced by azoxymethane (AOM) in male F344 rats. Eight weeks after AOM treatment, animals were fed diets containing Rosuvastatin and difluromethylornithine (DF...
