Esophageal carcinoma: CT findings

Area of Science:

• Oncology
• Radiology
• Surgical Oncology

Background:

• Esophageal cancer staging is critical for treatment planning.
• Transhiatal blunt esophagectomy is a surgical option for esophageal cancer.
• Accurate preoperative staging impacts surgical decision-making.

Purpose of the Study:

• To evaluate the accuracy of preoperative computed tomography (CT) in staging esophageal cancer.
• To determine the role of CT in assessing resectability for transhiatal blunt esophagectomy.

Main Methods:

• Retrospective review of preoperative CT scans from 33 esophageal cancer patients.
• Comparison of CT staging with surgical and pathological findings (TNM classification).
• Assessment of CT accuracy in evaluating tumor invasion (aortic, tracheobronchial) and metastases.

Main Results:

• Only 13 out of 33 tumors were accurately staged using CT based on the TNM classification.
• CT demonstrated low accuracy in evaluating aortic invasion, limiting its use in assessing resectability.
• Few patients presented with tracheobronchial invasion, aortic invasion, or hepatic metastases.

Conclusions:

• Preoperative CT staging has limited accuracy for esophageal cancer patients undergoing transhiatal blunt esophagectomy.
• CT's utility in assessing resectability is compromised by its inaccuracy in detecting critical invasive features.
• Further advancements in imaging are needed for precise preoperative staging and surgical planning in esophageal cancer.
