Summary
Computed tomography (CT) accurately stages esophageal carcinoma, assessing tumor invasion and lymph node involvement. This imaging technique improves surgical planning and reduces the need for diagnostic thoracotomy.
Area of Science:
- Oncology
- Radiology
- Surgical Oncology
Background:
- Esophageal carcinoma staging is crucial for treatment planning.
- Accurate preoperative assessment of tumor extent and lymph node status is essential.
Purpose of the Study:
- To evaluate the accuracy of computed tomography (CT) in staging esophageal carcinoma.
- To compare CT findings with surgical and pathological results.
- To assess the role of CT in determining local tumor resectability and guiding therapeutic strategy.
Main Methods:
- Prospective study of 83 patients with esophageal carcinoma.
- Computed tomography (CT) examination.
- Comparison of CT data with intraoperative, postmortem, and microscopical findings in 74 patients.
Main Results:
- CT T staging accuracy was 88% compared to surgery/autopsy and 82% to microscopy.
- Sensitivity, specificity, and accuracy for detecting infiltration of surrounding structures were 87%, 91%, and 89%, respectively.
- CT detected lymph node metastases in 68% of affected patients and provided detailed tumor information, including distant metastases.
Conclusions:
- Computed tomography (CT) is a highly accurate tool for staging esophageal carcinoma.
- CT findings correlate well with surgical and pathological data, aiding in the assessment of local tumor resectability.
- CT enables more precise surgical and therapeutic planning, potentially minimizing the need for diagnostic thoracotomy.
