Introduction Preoperative staging of rectal cancer is considered essential to select patients adequately for different therapeutic regimes. The aim of the present study was to evaluate the accuracy of endorectal ultrasonography in preoperative staging of rectal cancer. MATERIALS AND METHODS Fifty rectal cancer patients (31 men, 19 women) underwent endorectal ultrasonography with a 7.5-MHz probe. Thirty-eight of these patients had preoperative chemoradiation and in these patients examination was done before and after the radiotherapy treatment. The results of examinations were compared with the histological findings of the resected specimens. RESULTS Histopathology showed 4 stage T0, 3 stage T1, 12 stage T2, 30 stage T3, and one stage T4 tumor. Nodal metastases were seen in 17 patients. The overall accuracy of endorectal ultrasonography for determining the depth of invasion (T stage) was 66% (33/50). The accuracy rate of T1 was 100% (1/1), T2 was 45% (9/20), T3 was 79% (22/28), and T4 was 100% (1/1). Overstaging was 18% (9/50) and understaging 16% (8/50). In staging lymph node metastasis, the overall accuracy rate was 70% (18/25) with 18% (9/50) overstaged and 12% (6/50) understaged. With regard to nodal involvement, sensitivity was 65% and specificity 73%. Regarding penetration of the rectal wall (stages T1 and T2 vs stages T3 and T4 / Dukes' classification A versus B), endorectal sonography showed sensitivity, specificity, and accuracy of 74%, 68%, and 72%, respectively. CONCLUSION Endorectal ultrasonography is a valuable diagnostic modality for rectal cancer staging. It is fast, safe, accurate, well tolerated by the patient and cheap procedure and therefore should be used as a diagnostic modality of the first choice in rectal cancer staging although one must take into consideration possible limitations in cases of preoperative chemoradiation.

Rectal Cancer Staging

Preoperative staging represents a crucial point for the management, type of surgery, and candidacy for neoadjuvant therapy in patient with rectal cancer. The most recent clinical guidelines in oncology recommend an accurate preoperative evaluation in order to address early and advanced tumors to different therapeutic options. In particular, potential pitfalls may occur in the assessment of T3 tumors, which represents the most common stage at diagnosis. The depth of tumor invasion is known to be an important prognostic factor in rectal carcinoma; as a consequence, the T3 imaging classification has a substantial importance for treatment strategy and patient survival. However, the differentiation between tumor invasion of perirectal fat and mesorectal desmoplastic reactions remains a main goal for radiologists. Magnetic resonance imaging (MRI) is actually considered as the best imaging modality for rectal cancer staging. Although the endorectal ultrasound (ERUS) is the preferred staging method for early tumors, it could also be useful in identifying perirectal fat invasion. Moreover, the addiction of diffusion weighted imaging (DWI) improves the diagnostic performance of MRI in rectal cancer staging by adding functional information about rectal tumor and adjacent mesorectal tissues. This study investigated the diagnostic performance of conventional MRI alone, in combination with the DWI technique and ERUS in order to assess the best diagnostic imaging combination for rectal cancer staging.

Locoregional Staging

Abstract In the last 20 years, endorectal ultrasound (ERUS) has been one of the main diagnostic methods for locoregional staging of rectal cancer. ERUS is accurate modality for evaluating local invasion of rectal carcinoma into the rectal wall layers (T category). Adding the three-dimensional modality (3-D) increases the capabilities of this diagnostic tool in rectal cancer patients. We review the literature and report our experience in preoperative 3-D ERUS in rectal cancer staging. In the group of 71 patients, the staging of preoperative 3-D endorectal ultrasonography was compared with the postoperative morphologic examination. Three-dimensional ERUS preoperative staging was confirmed with morphologic evaluation in 66 out of 71 cases (92.9%). The detection sensitivities of rectal cancer with 3-D ERUS were as follows: T1, 92.8%; T2, 93.1%; T3, 91.6%; and T4, 100.0%; with specificity values of T1, 98.2%; T2, 95.4%; T3, 97.8%; and T4, 98.5%. Three-dimensional ERUS correctly categorized patients with T1, 97.1%; T2, 94.3%; T3, 95.7%; and T4, 98.5%. The percentage of total overstaged cases was 2.75% and that of understaged cases was 6.87%. The metastatic status of the lymph nodes was determined with a sensitivity of 79.1% (19 of 24), specificity of 91.4% (43 of 47), and diagnostic accuracy of 87.3% (62 of 71). In our experience, 3-D ERUS has the potential to become the diagnostic modality of choice for the preoperative staging of rectal cancer.

Endorectal ultrasonography is valuable method for accurate local staging of rectal cancer. Precise evaluation of tumor stage is essential for optimal therapy planning in patients with rectal cancer. Furthermore, it has great influence on the resectability and the risk of recurrence following resection. Endorectal ultrasonography has become the most common diagnostic tool for locally staging rectal cancer due to its advantages over magnetic resonance imaging (MRI) and computer tomography (CT). Among these diagnostic modalities ERUS has been known to be most accurate. Moreover, endorectal ultrasonography is inexpensive and quick diagnostic procedure associated with minimal discomfort to the patient. However, the use of CT, MRI, and more recently magnetic resonance imaging with endorectal coil often remains necessary. These modalities may be useful supplements in patients with suspected T4 lesion, when endorectal ultrasonography is technically unsuccessful and in cases of diagnostic dilemma. Major improvements in diagnostic and staging of rectal cancer have led to stage-oriented surgery, planning of therapy individually for each patient, reduce of local recurrences, and better overall survival. This article reviews the current use of endorectal ultrasonography in preoperative staging of rectal cancer as the most practical and accurate diagnostic modality for preoperative locoregional staging of rectal cancer at this time.

Endorectal ultrasonography has become important part of preoperative staging of rectal cancer, providing adequate information for clinical decision- making in many cases. However, with the currently available ultrasonographic equipment and techniques, a good deal of relevant information may remain hidden. The advent of high-resolution three-dimensional endoluminal ultrasound, constructed from a synthesis of standard two-dimensional cross-sectional images, and of "Volume Render Mode," a technique to analyze information inside a threedimensional volume, promises to improve the accuracy of rectal cancer staging. The anatomic structures in the pelvis, the axial and longitudinal extension of the tumor, the presence of slight or massive submucosal invasion in early rectal cancer may be imaged in greater detail. This additional information will bring an improvement for both planning and conduct of surgical procedures.
