Utility of tumor markers in determining resectability of pancreatic cancer.
HYPOTHESIS Despite advances in preoperative radiologic imaging, a significant fraction of potentially resectable pancreatic cancers are found to be unresectable at laparotomy. We tested the hypothesis that preoperative serum levels of CA19-9 (cancer antigen) and carcinoembryonic antigen will identify patients with unresectable pancreatic cancer despite radiologic staging demonstrating resectabl...

15 صفحه اولThe Predictive Value of Abdominal Ultrasonography Compared to CT Scan for the Evaluation of Pediatric Lymphoma
Background: Given the children's susceptibility to the harmful radiation of computerized tomography (CT) scans, ultrasonography can be a good alternative in staging pediatric lymphoma. The present study aimed to assess the predictive value of abdominal ultrasonography compared to CT scan in children with lymphoma. Materials and Methods: Fifty-two children with confirmed lymphoma were included ...
متن کاملDiagnostic value of CT perfusion imaging for parotid neoplasms.
OBJECTIVES To assess the value of CT perfusion imaging in the differentiation of different histological categorization of benign tumours from malignant tumours in patients with parotid neoplasms. METHODS CT perfusion was successfully performed in 62 patients with parotid neoplasms whose diagnoses were confirmed by surgery or biopsy. The software generated a tissue time-density curve (TDC) and...
متن کاملPredictive factors of resectability and postoperative outcome for pancreatic cancer
Pancreatic cancer still remains a challenge for surgeons. The goal of surgery is to ensure oncological R0 resection as positive resection margin is associated with poor prognosis. The purpose of this study is to determine the utility of age, ASA score, bilirubin and albumin value, CA 19-9 and imaging modalities for predicting the resectability in pancreatic cancer. This retrospective study cons...
