Abstract
We evaluated in 214 patients with primary colorectal cancer the prognostic value of the preoperative serum levels of CEA and CA195. For CEA these levels were above the cutoff of 6 ng/ml in 31.3% of patients, whereas for CA195 they were higher than 12 U/ml in 35.9% of patients. The simultaneous use of both antigens increased the sensitivity to 49%, which was significantly higher than that of CEA (p<0.001) and CA195 (p<0.01) taken singly. The mean preoperative CEA levels were significantly (p<0.001) correlated with Dukes’ stage only, while there was a significant correlation between preoperative serum levels of CA195 and Dukes’ stage (p<0.001), grade of differentiation (p<0.01) and tumor location (p<0.05). The results indicated that high preoperative serum levels of CEA and CA195 were associated with a shorter overall survival (p<0.0001). In addition, separate Cox multivariate analysis showed that preoperative CA195 was, after Dukes’ stage, the strongest factor to predict overall survival (p<0.0001).

Abstract
BACKGROUND This study intended to investigate whether residence in areas polluted by heavy industry, waste incineration, a high density of traffic and housing or intensive use of pesticides, could contribute to the high incidence of cancer observed in Flanders. METHODS Subjects were 1583 residents aged 50-65 from 9 areas with different types of pollution. Cadmium, lead, p,p'-DDE, hexachlorobenzene, PCBs and dioxin-like activity (Calux test) were measured in blood, and cadmium, t,t'-muconic acid and 1-hydroxypyrene in urine. Effect biomarkers were prostate specific antigen, carcinoembryonic antigen and p53 protein serum levels, number of micronuclei per 1000 binucleated peripheral blood cells, DNA damage (comet assay) in peripheral blood cells and 8-hydroxy-deoxyguanosine in urine. Confounding factors were taken into account. RESULTS Overall significant differences between areas were found for carcinoembryonic antigen, micronuclei, 8-hydroxy-deoxyguanosine and DNA damage. Compared to a rural area with mainly fruit production, effect biomarkers were often significantly elevated around waste incinerators, in the cities of Antwerp and Ghent, in industrial areas and also in other rural areas. Within an industrial area DNA strand break levels were almost three times higher close to industrial installations than 5 kilometres upwind of the main industrial installations (p < 0.0001). Positive exposure-effect relationships were found for carcinoembryonic antigen (urinary cadmium, t,t'-muconic acid, 1-hydroxypyrene and blood lead), micronuclei (PCB118), DNA damage (PCB118) and 8-hydroxy-deoxyguanosine (t,t'-muconic acid, 1-hydroxypyrene). Also, we found significant associations between values of PSA above the p90 and higher values of urinary cadmium, between values of p53 above the p90 and higher serum levels of p,p'-DDE, hexachlorobenzene and marker PCBs (PCB 138, 153 and 180) and between serum levels of p,p'-DDE above the p90 and higher serum values of carcinoembryonic antigen. Significant associations were also found between effect biomarkers and occupational or lifestyle parameters. CONCLUSION Levels of internal exposure, and residence near waste incinerators, in cities, or close to important industries, but not in areas with intensive use of pesticides, showed positive correlations with biomarkers associated with carcinogenesis and thus probably contribute to risk of cancer. In some rural areas, the levels of these biomarkers were not lower than in the rest of Flanders.

Abstract
BACKGROUND Up to now, there is still no ideal tumor marker in early diagnosis and effective monitoring, especially for surgical resection of colorectal cancer (CRC). The aim of the present study was to evaluate the application of urinary normal and modified nucleosides in diagnosis and surgery monitoring of CRC. METHODS Between October 2002 and July 2003, 52 consecutive patients with pathological confirmed CRC were enrolled. Spontaneous urine samples were collected 1 day before surgery and on day 8 postoperatively, and 14 urinary nucleosides were determined by reverse-phase high-performance liquid chromatography (RP-HPLC). Another 62 healthy people were also studied as control. The clinical routine tumor markers, serum carcinoembryonic antigen (CEA), carbohydrate antigen (CA)199, CA125, and alpha-fetoprotein (AFP) of CRC patients, were correspondingly evaluated by electrochemiluminescent immunoassay. RESULTS The levels of 11 out of 14 of the determined urinary nucleosides in the CRC group were much higher than those of normal controls. Through the principal component analysis of these 14 nucleosides, 76.9% of CRC patients were correctly classified. The sensitivity of this analysis was much higher than that of CEA (38.5%), CA199 (40.4%), CA125 (15.4%), and AFP (17.3%; P < 0.01). Receiver operating characteristic (ROC) curve analysis of 1-methylguanosine (m1G) and pseudouridine (Pseu) showed good sensitivity-specificity profiles of the diagnosis of CRC. The elevated levels of the nine nucleosides significantly decreased after curative resection of 40 CRC cases. The data also showed that the preoperative levels of some nucleosides were positively related with tumor size and Dukes staging of CRC. CONCLUSION The evaluation of normal and modified urinary nucleosides might become novel tumor markers, which will be facilitated in the clinical setting and helpful in the diagnosis, management and follow up of CRC. Pseu and m1G may be more promising for clinical use and be worthy of further studies in the near future.
