Pentraxin-3, endothelin-1, some biochemical parameters and hematology in bovine respiratory disease complex.

Abstract. Background: Infectious bovine respiratory disease complex (BRDC) is one of the world's major livestock problems. Aims: The study aimed to determine the diagnostic importance of pentraxin-3, endothelin-1, clinical biochemistry, and hematological parameters in infectious BRDC. Methods: Animals in this study were Simmental breed, 1-7 years old, untreated, and healthy and BRDC cattle (40 cattle with BRDC in the disease group, and 10 healthy cattle in the control group). Clinical findings such as general posture, respiratory rate per minute, rectal temperature, heart rate per minute, and mental posture of the diseased cattle were recorded. Blood samples were taken from the jugular vein only once from all cattle. Complete blood count from blood samples was measured in an automatic complete blood count device, biochemical parameters in an autoanalyzer, and pentraxin-3 and endothelin-1 were measured by ELISA method. Results: Rectal temperature, respiratory and pulse rates per minute, total leukocyte count, gamma-glutamyl transferase, urea, total bilirubin, lactate dehydrogenase, creatine kinase, pentraxin-3 and endothelin-1 concentrations were found to be statistically higher in BRDC group than those in the control group (P<0.001). Conclusion: Pentraxin-3 and endothelin-1 levels were statistically significantly higher in the BRDC group compared to the control group. As a result, pentraxin-3 and endothelin-1 were found to be diagnostically important in cattle diagnosed with BRDC.

Low risk stage I endometrial carcinoma: prognostic factors and outcomes.

OBJECTIVES: The aim of the study is to evaluate clinical features of patients with low-risk stage I endometrium cancer, who received adjuvant therapy or followed with observation only and to analyse the effects of known prognostic factors in this group of patients. MATERIALS AND METHODS: A total of 246 patients (median age: 53, range: 31-77) with low-risk stage I endometrial cancer, who were just followed postoperatively (156 patients) or received adjuvant radiotherapy (90 patients) between 1996 and 2007 were reviewed retrospectively. RESULTS: Local recurrence was detected in four patients, distant metastasis occurred in seven patients, and two patients had both local recurrence and distant metastasis. The 83.3% of recurrences were on the vaginal stump. Five- and ten-year local control (LC) and overall survival (OS) rates are 97.6%, 97.6% and 96.4%, 93.5% in the observation and adjuvant therapy groups, respectively, whereas distant control rates are 96.7% and 96.3%. In multivariate analysis, only age and lymphovascular invasion (LVI) were found to affect OS and disease-free survival (DFS). CONCLUSIONS: LC and OS rates are high in the low-risk group of patients; however, current adjuvant therapies did not improve the outcomes. Age over 60 years and the presence of LVI have negative effects on outcomes in this group of patients.

Postoperative chemoradiation in patients with localized gastric adenocarcinoma: single center experience.

BACKGROUND: 5-Fluorouracil (FU)-based chemotherapy (CT) and concurrent 45 Gy radiotherapy (RT) is one of the standard postoperative approaches currently used in gastric carcinoma. The high toxicity rates of this treatment leads to interruption of treatment in the majority of patients. In our study, we investigated the rates of toxicity and treatment discontinuation observed during postoperative FU-based chemoradiotherapy (CRT); retrospectively evaluated the effect of CRT and the other prognostic factors on local and distant control and survival. PATIENTS AND METHODS: A total of 160 patients consisting of 97 total and 63 subtotal gastrectomy receiving postoperative CRT, have been studied retrospectively. RESULTS: Patients who had to discontinue the treatment for a median of 6 (range, 3-13) days experienced toxicity during treatment at a rate of 43%. During the 21 (range, 4-68) months of follow-up local recurrences were observed in 8 (5%) patients and distant recurrences were observed in 41 (25.6%) patients. While the 1-3 year overall survival (OS) rates were 75% and 42%, 13-year disease-free survival (DFS) rates were 63% and 42%, respectively. In the univariate analysis for OS and DFS demonstrated statistical significance for below those 60 years of age, D1-D2 dissection type, negative surgical margin, early treatment beginning, the absence of invasion, and early stage disease. D1D2 dissection type, early treatment beginning, age below 60 years and early stage disease significantly improve OS and DFS in multivariate analysis. CONCLUSIONS: Survival is worse in patients older than 60 years, had late treatment beginning, advanced stage and D0 dissection.

A retrospective comparison of concurrent 5-fluorouracil or oral UFT in postoperative chemoradiation for gastric adenocarcinoma.

PURPOSE: 5-fluoro-uracil (FU) is a common agent in postoperative chemoradiation in gastric adenocarcinoma. However, FU is not well tolerated in a significant proportion of patients. UFT, a fixed combination of the oral FU prodrug tegafur with uracil, is one of the agents used instead of FU in such cases. We retrospectively compared the toxicity, local and distant control and survival rates with FU or oral UFT during concurrent radiotherapy to assess the role of UFT instead of FU. PATIENTS AND METHODS: We conducted a retrospective analysis of survival, disease control and toxicity data in 52 patients treated with postoperative chemoradiation following total or subtotal gastrectomy for gastric adenocarcinoma with either FU or UFT between January 2003 and December 2004. RESULTS: Median follow-up was 20 months (range: 3-59), median survival time was 23 (+/-6.08) months and 1-3 years overall survival (OS) rates were 64.9-39% for all patients. Compared with the UFT regimen, the incidence of treatment interruption was greater with FU (p=0.023), but no significant differences were seen in local control (p=0.40), distant recurrences (p=0.83) and survival rates (p=0.8657) among patients. CONCLUSION: Concurrent UFT with radiotherapy seems to be a more tolerable and an equally effective regimen in the postoperative treatment of gastric adenocarcinoma when compared to FU.
