Circulating p53 Antibody in Patients with Colorectal Cancer

The presence of serum anti-p53 antibody has been reported to be associated with survival of patients with breast cancer, ovarian cancer, and hepatocellular carcinoma. To clarify prognostic significance of p53 antibody in colorectal cancer, serum p53 antibody was measured in patients with colorectal cancer. The 89 patients included 71 with colorectal cancer and 18 with colon polyp. An enzyme-linked immunosorbent assay was used to detect p53 antibodies in serum. Clinicopathological parameters such as age, sex, degree of differentiation of cancer, location of tumor, liver metastasis, stage classification, Dukes classification, CEA, CA19-9, and immunostaining of p53 and anti-p53 antibody were evaluated as prognostic factors of colorectal cancer. p53 antibody was positive in 18 of 71 (25%) with colorectal cancer, whereas it was positive in only 1 of 18 (6%) with colon polyp. The patients with p53 antibody had higher CEA and CA19-9 levels, higher positive rates of p53 protein expression in cancer cells, and higher liver metastasis rates. The p53 antibody positivity at stage classification I–IIIb/Dukes classification A–C was significantly lower than that at stage classification IV/Dukes classification D. Overall survival in colorectal cancer patients with p53 antibody was significantly shorter than in those without p53 antibody. A Cox regression analysis showed that liver metastasis, stage classification, Dukes classification, CA19-9, and p53 antibody were significant prognostic factors in colorectal cancer. Serum anti-p53 antibody could serve as one of the prognostic factors in patients with colorectal cancer.     

结直肠癌患者根治术前血清CEA和CA19-9表达水平对预后的预测价值

目的探讨结直肠癌患者根治术前CEA、CA19-9水平对预后的预测价值。 方法回顾性分析复旦大学附属肿瘤医院2003年12月至2007年1月间491例接受根治性切除的Ⅱ、Ⅲ期结直肠癌患者临床资料,包括患者术前血清CEA和CA19-9水平、临床病理资料及预后情况。利用单变量和多变量分析患者年龄、性别、肿瘤部位、肿瘤分化、TNM分期、肿瘤侵犯深度及淋巴结转移个数与预后的关系。 结果患者术前血清CEA和CA19-9水平、TNM分期、淋巴结转移数、肿瘤侵犯深度、肿瘤的分化都与预后相关。在多变量分析中,CEA和CA19-9水平、TNM分期、肿瘤分化是总生存的独立预测因素,CA19-9水平、TNM分期、肿瘤分化是无病生存的独立预测因素。 结论术前血清CA19-9与CEA水平均对结直肠癌患者的预后有预测价值。CA19-9水平应该作为常规的术前检查指标,对CEA检测结果有补充作用。

Value of serum carbohydrate antigen 19-9 for predicting extrahepatic metastasis in patients with liver metastasis from colorectal carcinoma

BACKGROUND/AIMS: Serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are frequently elevated in patients with colorectal carcinoma. However, the predictive utility of these two markers has not been fully investigated in patients with liver metastasis. METHODOLOGY: We retrospectively analyzed data obtained from 90 hepatectomy or non-hepatectomy patients with liver metastases from colorectal carcinoma. We examined correlation between serum levels of CEA and CA19-9 and other clinicopathologic factors and performed univariate and multivariate analyses to determine the impact of these tumor markers on extrahepatic metastasis after admission to our hospital. RESULTS: CEA elevation correlated to advanced age (> or = 60 years), and CA19-9 elevation correlated with the site (colon) of primary tumor. Univariate analysis showed that treatment without hepatectomy, > or = 4 hepatic tumors, and CA19-9 elevation had been an adverse effect on extrahepatic disease-free survival time after admission. Multivariate analysis showed that CA19-9 elevation (risk ratio, 1.84) and treatment without hepatectomy (risk ratio, 1.62) had a significant effect on extrahepatic disease-free time. CONCLUSIONS: In patients with colorectal liver metastasis, elevation of serum CA19-9 is a risk factor for extrahepatic metastasis, and CEA appears to be useless for predicting extrahepatic metastasis in these patients.     

结直肠癌患者血清中血管内皮生长因子和一氧化氮表达水平及其临床意义

Serum Carcinoembryonic Antigen in Relation to Survival,DNA Ploidy Pattern,and Recurrent Disease in 406 Colorectal Carcinoma Patients

Serum carcinoembryonic antigen (CEA) levels in relation to survival, flow cytometric DNA ploidy pattern, Dukes stage, and recurrent disease was prospectively evaluated in 406 patients with colorectal carcinoma. In 246 patients (61%) the carcinomas were DNA aneuploid. Increased preoperative CEA levels (>5 μg/l) were found in 151 of 363 evaluable patients (42%). Dukes stage-B patients with preoperative CEA elevation showed significantly poorer prognosis than those with normal CEA values (p = 0.001). A weak but significant correlation was found between preoperative CEA level and Dukes stage (Kendall's α = 0.25, p < 0.01). Of 50 evaluable patients with clinical recurrence and postoperative normal or normalized CEA levels, 28 (56%) had a rise in CEA before or at the time of clinical recurrence. The sensitivity of the CEA test for primary and for recurrent disease was not significantly different in the DNA aneuploid and the DNA near-diploid groups.     

The use of tumor markers as predictors of prognosis in gastric cancer

BACKGROUND/AIMS: The aim of this study was to evaluate the prognostic significance of serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA19-9) levels in patients with gastric cancer. METHODOLOGY: During the period January 2000 and January 2003, 36 patients operated for primary gastric cancer, at Sisli Etfal Training and Research Hospital, Department of General Surgery, were analyzed. Serum CEA and CA19-9 levels were determined preoperatively and the correlation between the elevated levels of tumor markers and several clinicopathological features, and survival were evaluated. RESULTS: Elevated serum CEA and CA19-9 levels were determined in 10 of 35 patients (28.6%), and 9 of 31 patients (29%), respectively, and both markers were elevated in 3 of 31 patients (9.6%). Elevated levels of CEA correlated with depth of invasion (p=0.018) and pathological stage (p=0.029); elevated levels of CA19-9 correlated with lymph node metastasis (p=0.026); and elevated levels of both markers correlated well with lymph node metastasis (p=0.031). The survival of patients with normal CEA levels was significantly better than those with elevated levels (p=0.0072). CONCLUSIONS: Preoperative serum CEA and CA19-9 levels may add useful information in patients with gastric carcinoma, and CEA level is a predictor of prognosis.
