The present prospective single-center study investigated the prognostic role of novel serum biomarkers in advanced pancreatic cancer (PC). Patients (pts) with locally advanced or metastatic PC treated with first-line palliative chemotherapy were included. Among others, the serum markers CYFRA 21-1, haptoglobin, serum-amyloid A (SAA), and 25-OH vitamin D3 were determined at baseline and categorized by pre-defined cut-offs [median values (MV), upper limits of normal (ULN), lower limits of normal (LLN), or the natural logarithm (ln)] and correlated with overall survival (OS). Among the 59 pts included, pre-treatment CYFRA 21-1 levels showed a strong correlation with OS independent of the applied cut-off (MV 4.9 ng/ml-14.2 vs. 4.2 months, HR 0.18, p = 0.001; ULN 3.3 ng/ml-14.2 vs. 4.4 months, HR 0.28, p = 0.003; [ln] CYFRA 21-1-HR 0.77, p = 0.013). Lower values of haptoglobin were additionally associated with an improvement in OS (categorized by LLN of 2.05 g/l-10.4 vs. 5.5 months, HR 0.46, p = 0.023; [ln] haptoglobin-HR 0.51, p = 0.036). Pts with baseline SAA values below the MV of 22 mg/l also had a prolonged OS (10.4 vs. 5.0 months, HR 0.47, p = 0.036). For 25-OH vitamin D3 levels, no significant correlation with OS was found. In multivariate analyses, pre-treatment CYFRA 21-1 levels (categorized by MV-HR 0.15, p = 0.032) as well as [ln] haptoglobin (HR 0.30, p = 0.006) retained their independent prognostic significance for OS. CYFRA 21-1, haptoglobin, and SAA might provide useful prognostic information in advanced PC. An external multicenter validation of these results is necessary. [ABSTRACT FROM AUTHOR]

Several independent serum biomarkers have been proposed as prognostic and/or predictive markers for colorectal cancer (CRC). To this date, carcinoembryonic antigen (CEA) remains the only recommended serological CRC biomarker. The present retrospective analysis investigates the prognostic value of several serum markers. A total of 256 patients with rectal cancer underwent surgery for curative intent in a university cancer center between January 1988 and June 2007. Preoperative serum was retrospectively analyzed for albumin, alkaline phosphatase (aP), beta-human chorionic gonadotropin, bilirubin, CA 125, cancer antigen 19-9, cancer antigen 72-4 (CA 72-4), CEA, CRP, CYFRA 21-1, ferritin, gamma-glutamyl transpeptidase, glutamate oxaloacetate transanunase, glutamate pyruvate transaminase, hemoglobin, haptoglobin, interleukin-6, interleukin-8, creatinine, lactate-dehydrogenase, serum amyloid A (SAA), and 25-hydroxyvitamin D. Cancer-specific survival (CSS) and disease-free survival (DFS) were estimated. Median follow-up time was 8.4 years. Overall 3- and 5-year CSS was 88.6 and 78.9 %, respectively. DFS rates were 72.8 % (3 years) and 67.5 % (5 years). Univariate analysis of CSS indicated aP, CA 72-4, CEA, and SAA as prognostic factors, while aP, CEA, and SAA were also prognostic with regard to DFS. Multivariate analysis confirmed SAA together with T and N stage as prognostic factors. According to UICC stage, CEA and SAA add prognostic value in stages II and III with regard to DFS and CSS, respectively. The combined use of CEA and SAA is able to identify patients with favorable and poor prognosis. In addition to tumor baseline parameters, routine analysis of SAA together with CEA provided markedly improved prognostic value on CSS and DFS in resected rectal cancer. [ABSTRACT FROM AUTHOR]

Background: The objective of this retrospective study was to assess the survival of patients after resection of hepatic and pulmonary colorectal metastases to identify predictors of long-term survival. Methods: Patients receiving chemotherapy alone were compared to patients receiving surgery and chemotherapy in a matched-pair analysis with the following criteria: UICC stage, grading, and date of initial primary tumor occurrence. Results: A total of 30 patients with liver and lung metastases of colorectal carcinoma underwent resection. In 20 cases, complete resection was achieved (median survival, 67 months). Incomplete resection and preoperatively elevated carcinoembryonic antigen (CEA) levels are independent risk factors for reduced survival. Patients developing pulmonary metastases prior to hepatic metastases had the worst prognosis. Surgical resection significantly increased survival compared to chemotherapy alone in matched-pair analysis (65 vs. 30 months, p = 0.03). Conclusions: Incomplete resection and elevated CEA levels are predictors of poor outcome. Matched-paired analysis confirmed that surgical resection in combination with chemotherapy appears to be superior to chemotherapy alone. [ABSTRACT FROM AUTHOR]
