Accordingly, three factors — intermittent bleeding or small bleeding, intraintestinal degeneration of human hemoglobin and inappropriate sampling — were likely the major reasons for a negative result on immunochemical fecal occult blood testing. Of these factors, intermittent bleeding has been identified as the major possible cause of a negative result of fecal occult blood testing […]

Randomized, controlled trials have shown that fecal occult blood screening for colorectal cancer using patient-collected stool is associated with reduced mortality from colorectal cancer. Some physicians perform fecal occult blood tests on stool obtained during the digital rectal examination in general practice; however, the clinical impact of this practice is controversial. Best quality drugs are […]

Dukes stage: Eighteen (60.0%) cases of cancer in the positive group and 12 (40.0%) cases in the negative group were classified as Dukes A, suggesting that the frequency of Dukes A cancer was highest in both groups. There was no significant difference in the combined frequency of cases classified as Dukes B and C between […]

Tumour site: In the group who tested positive for fecal occult blood, the lesion sites were the rectum in 20 patients (80.0%), the left side of the colon (sigmoid colon and descending colon) in 15 patients (48.4%) and the right side of the colon (transverse colon, ascending colon and cecum) in four patients (50.0%). In […]

Of 9952 subjects who participated in the medical checkup for colorectal cancer, 5830 were male and 4122 were female. The average age of the subjects was 53.6 years (male 54.8 years, female 51.4 years). The results of an immunochemical fecal occult blood test were positive in 786 subjects (7.9%; 95% CI 7.4% to 8.4%; male […]

Subjects for the cross-sectional study were selected from participants in an annual employee medical checkup from April 1, 1990 to March 31, 1999. The two hospitals for the medical checkups were located in central Nagano Prefecture. Physicians from the department of endoscopy of each hospital carried out both colonoscopy and immunochemical fecal occult blood testing […]

When testing stool for fecal occult blood to detect colorectal cancer, stool is collected by two methods: by testing stool specimens obtained as part of routine screening, and by testing stool specimens obtained during the digital rectal examination as part of the physical examination or for screening purposes. However, the appropriate evaluation of a positive […]

Important limitations of this study include the aggregation of the data on hospital costs using per diem rates. To be more meaningful, it would be necessary to analyze the intensity of care provided during the hospital stay, perhaps by considering the operations performed, the duration of operations, the number of intensive care days, the diagnostic […]

Using separation dates to define the relevant hospital admissions may have led to some bias in the results. At the time of diagnosis, using hospital admissions with separation days at or after the date of diagnosis should have captured all relevant activity at the beginning of the three-year time period. This was confirmed by the […]

A complete model estimating the direct costs of CRC care would include costs of diagnosis; initial treatment (in or out of hospital) including surgery; chemotherapy and radiotherapy; adjuvant therapy in the form of chemotherapy to prevent recurrence in patients who are thought to be cured by their initial treatment; and palliative treatment both in hospital […]
