Increase in both CEA and CA19-9 in sera is an independent prognostic indicator in colorectal carcinoma

BACKGROUND AND OBJECTIVES: Carcinoembryonic antigen (CEA) and carbohydrate antigen (CA19-9) are well known to be the most common tumor markers of colorectal carcinomas. However, the significance of increase in these markers to predict the prognosis of the patients remains a problem for debate. METHODS: One hundred three patients with colorectal carcinoma, who had been treated by resection and reconstruction of digestive tracts were studied. Correlation of preoperative serum value of CEA and CA19-9 with clinicopathologic features including prognosis of the patients was investigated. RESULTS: Preoperative elevation of both of the two markers proved to be an independent prognostic indicator, however, an elevation of only one of the two markers did not obtain a prognostic significance. CONCLUSIONS: Combined data of preoperative increase in CEA and CA19-9 in sera can provide a powerful and useful information to predict prognosis of patients with colorectal carcinoma.

Selecting surgical candidates with locally advanced pancreatic cancer: a review for modern pancreatology

Pancreatic cancer (PC) is likely to become the second leading cause of malignancy-associated mortality within the next 10 years and surgery remains the best hope for cure. The introduction of effective neoadjuvant treatment (NAT) has increased the resection rate of PC in the era of contemporary pancreatology. This review summarizes the surgical selection criteria for locally advanced PC (LAPC), by focusing on the commonly used predictors for resectability and better overall survival outcome. Based on the currently available evidence, the role of change in carbohydrate antigen 19-9 (CA 19-9) and patient’s tumor response to NAT are critical in surgical candidacy selection. Although, consensus on surgical candidacy selection for LAPC still needs to be made, several data have shown that surgery provides the most optimistic chance of cure for PC. Surgery is, therefore, recommended whenever the benefits of pancreatectomy outweigh surgical complications, and the chance of local or distant metastases in the postoperative setting is low. This review also provided our insight for and experience in selecting surgical candidates by focusing on optimizing the overall survival of LAPC patients. Nevertheless, a collaborative approach to formulating standardized criteria for surgical candidate selection and treatment guidelines for LAPC is a common goal that pancreatologists worldwide should focus on.

Diagnostic value of preoperative serum carcinoembryonic antigen and carbohydrate antigen 19-9 in colorectal cancer

Background

Since the first introduction of tumour markers, their usefulness for diagnosis has been a challenging question. The aim of the present prospective study was to investigate, in colorectal cancer patients, the relationship between preoperative tumour marker concentrations and various clinical variables.

Methods

The study prospectively enrolled 131 consecutive patients with a confirmed diagnosis of colorectal carcinoma and 131 age- and sex-matched control subjects with no malignancy. The relationships of the tumour markers carcinoembryonic antigen (cea) and carbohydrate antigen (ca) 19-9 with disease stage, tumour differentiation (grade), mucus production, liver function tests, T stage, N stage, M stage were investigated.

Results

Serum concentrations of cea were significantly higher in the patient group than in the control group (p = 0.001); they were also significantly higher in stage iii (p = 0.018) and iv disease (p = 0.001) than in stage i. Serum concentrations of cea were significantly elevated in the presence of spread to lymph nodes (p = 0.005) in the patient group. Levels of both tumour markers were significantly elevated in the presence of distant metastasis in the patient group (p = 0.005 for cea; p = 0.004 for ca 19-9).

Conclusions

Preoperative levels of cea and ca 19-9 might provide an estimate of lymph node invasion and distant metastasis in colorectal cancer patients.     

Pancreatoduodenal carcinoma: a clinicopathologic study of 304 patients and immunohistochemical observation for CEA and CA19-9

A total of 304 patients with pancreatoduodenal carcinoma were studied clinicopathologically and immunohistochemically in order to clarify features of carcinoma of four different sites of origin; carcinoma of the ampulla of Vater (Am), the distal common bile duct (DCBD), the head of the pancreas (PH), and the extra-ampullary duodenum (Du). The mean greatest diameter of 87 PH was 3.5 cm compared with 2.7 cm of 149 Am and 2.7 cm of DCBD. Histopathologically, 40% of Am were papillary adenocarcinoma, while about half of DCBD, PH and Du were tubular adenocarcinoma. PH invaded lymphatic (85%), vascular (62%), and perineural (95%) spaces and metastasized lymph nodes (72%) more frequently than Am (77%, 35%, 24%, 50%), DCBD (47%, 61%, 65%, 45%), and Du (76%, 29%, 35%, 65%), respectively. More than 50% of PH invaded the resected margins, whereas in only 2% of Am, the surgical margins were affected by malignant cells. Immunohistochemically, PH was more frequently positive for both carcinoembryonic antigen (CEA) (98%) and carbohydrate antigen (CA) 19-9 (91%) than Am (83%, 62%), DCBD (94%, 58%), and Du (56%, 11%), respectively. The stromal staining type of CEA and CA 19-9 was more frequently seen in PH (27%, 44%) than in Am (9%, 31%), DCBD (11%, 8%) and Du (0%, 0%), showing a more dedifferentiated nature of PH. The cumulative 3-year survival rate of 87 patients with PH (15%) was worse than that of 149 with Am (42%, P less than 0.001), of 51 with DCBD (25%) and of 17 with Du (58%, P less than 0.001). The survival curve of 87 with PH was worse than that of 51 with DCBD, of 149 with Am (P less than 0.001) and of 17 with Du (P less than 0.001). Cox regression analysis, using eleven profound prognostic variables, revealed that venous invasion, perineural infiltration, surgical margin, and histopathologic type were profound prognostic factors. Pancreatic carcinoma has a more dedifferentiated histopathologic nature, showing a more aggressive growth and fares worse than Am, DCBD, and Du.
