CORRELATION BETWEEN PREOPERATIVE COMPUTED TOMOGRAPHY AND POSTOPERATIVE PATHOLOGICAL MEASUREMENTS OF TUMOR LENGTH IN CASES OF CARCINOMA ESOPHAGUS
Keywords:
Computed tomography, esophageal cancer, tumor lengthAbstract
Objective: To compare the result of preoperative computed tomography (CT) and postoperative pathological
measurements of tumor length in cases of carcinoma esophagus.
Material and Methods: Computed tomography thorax and upper abdomen with oral and intravenous contrast was
done of biopsy proven 100 cases of carcinoma esophagus. The patients were then referred to Cardiothoracic
Surgery Unit, PGMI, Lady Reading Hospital for esophagectomy. Tumor lengths measured on preoperative computed
tomography and on the post-operative resection specimens were recorded.
Results: Out of 100 patients, 65 were male and 35 were female. Age ranged from 18 to 82 years with a mean age of
59.9 years. Middle and lower third tumors were present in 50 cases each. On CT scan the esophageal tumor length
ranged from 1 cm to 13 cm with a mean length of 4.96 cm, whereas pathological measurements of esophageal tumor
length ranged from 1cm to 12 cm with a mean length of 4.72 cm. There was a significant linear correlation between
CT and pathology measurements of esophageal tumor lengths.
Conclusion: CT assessments generally overestimate macroscopic esophageal tumor length and should not be the
only modality used for management decisions.
