Rectal Polyps and Early Rectal Cancer Assessment by Three-Dimensional Endorectal Ultrasonography

e14149 Background: Local contact radiotherapy for early rectal cancer is an accepted treatment in most centers but still controversial in some centres. However, the old Philips machine is obsolete and many centers are unable to continue treating patients using this technique. A new RT 50 Papillon machine is now commercially available and there is a new hope for elderly patients and others who whish to avoid major surgery or permanent stoma. Methods: Although contact radiotherapy has been in clinical use for the past 80 years it is still not regarded as standard treatment in many centers around the world. This is due to the fact that there were no large randomized trials to prove its efficacy against standard surgical treatment. ICONE group has launched CONTEM trials, which are observational trials that combine Contact RT with TEMS for various stages of malignant rectal polyps. Results: ICONE group meets annually and organized courses for contact radiotherapy. So far, 10 centers in Europe have now been trained. We hope to start the CONTEM trials later this year. The data from these trials will be collected centrally in Nice and updated annually. The results will be published later. Conclusions: At present approximately 30-50% of patients with early (T1N0) low rectal cancer (<6cm) are being over treated with APR. Revival of contact radiotherapy allows multimodality treatment for selected patients to avoid major surgery and permanent stoma. We hope the CONTEM trials will provide some evidence in this approach for suitable patients with early rectal cancer. [Table: see text]

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.
