ThTP4.13 Discrepancy between preoperative MRI staging and post-operative histopathology staging in rectal cancer patients who had primary surgery. A retrospective study at a District General Hospital

Preoperative staging of rectal cancer.

Detailed preoperative staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require preoperative therapy for tumour regression. This information can be used to instigate neoadjuvant therapy in those patients with poor prognostic features prior to disturbing the tumour bed and potentially disseminating disease. The design of trials incorporating MR...

Correlation of Preoperative HE-4 and CA125 with Ovarian Cancer Staging in Ahvaz Imam Khomeni Hospital

  Background: Given that ovarian cancer symptoms are nonspecific and that appropriate surgical staging and pathological grading are important for the best treatment and prognosis of patients, this study aimed to determine the correlation of preoperative serum levels of CA125 and He4 with staging and grading. Materials and Methods: This cross-sectional study recruited 29 patients with epithelial...

Preoperative imaging staging of rectal cancer.

Carcinomas of the rectum are associated with a significant local and distant recurrence rate. Not all patients are appropriate candidates for preoperative radiation therapy. Preoperative identification of those most likely to benefit from neoadjuvant therapy is important. There is no general consensus on the role of endorectal ultrasonography, computed tomography (CT), and magnetic resonance im...

Staging of Laryngeal and Hypopharyngeal Cancer: Computed Tomography versus Histopathology

Introduction: Computed tomography (CT) imaging is the choice of investigation for evaluation of extent of tumor under the mucosa, locally and regionally. This study was undertaken to assess the accuracy of preoperative CT imaging in the staging of carcinoma of the larynx and hypopharynx.   Materials and Methods: In this retrospective study, all cases who were clinically (c) staged T3–T4 and w...
