ABSTRACT

At the Cancer Hospital, the incidence of rectal cancer has increased, with computed tomography the method of choice for diagnosis and staging which, added to magnetic resonance of pelvis, has improved diagnosis of rectal cancer, raising sensitivity to up to 86% of cases.
The primary objective of this review is description and analysis of findings from thoracic and abdominopelvic computed tomography and magnetic resonance of pelvis, and staging and prognostic factors, in addition to determining incidence by age and gender for this pathology in our hospital unit
Material and Methods: Images were analyzed from 26 cases of patients with diagnosis of rectal adenocarcinoma, with a Siemens 64 detector CT scanner and Phillips 3 T resonator, and the data was stored in a PACS (Picture Archiving and Communications System) system for statistical analysis.
Results: Of the 26 cases of rectal cancer, males were the predominant gender with 65%, 38% in an age range of 51-60 years. Sixty-nine percent of rectal tumors were located in the lower rectum. In 73% of the patients it was determined that it was unviable to preserve the sphincter, the circumferential margin of resection in 85% was compromised, the maximum extramural tumor depth was greater than 5 mm in 96% of cases. Ninety-six percent presented concentric growth, with compromise of mesorectal fat in 100%. Adenopathies in iliac chains were identified in 7 patients, retroperitoneal adenopathies in 1 patient, and perirectal nodules in 24 patients. Fifty percent presented contiguous metastasis and 8% distant metastasis.
