Short-course versus long-course neoadjuvant radiotherapy for lower rectal cancer: a systematic review.
OBJECTIVE To analyse the efficacy of short-course (SCRT) versus long-course radiotherapy/chemoradiation (LCRT) as a neoadjuvant modality for the management of lower rectal cancer (LRC). METHODS A systematic review of the literature was undertaken. Selected trials were analysed to generate a summative outcome. RESULTS Seven trials on the efficacy of SCRT versus LCRT as a neoadjuvant modality...
متن کاملPatterns of Pelvic Radiotherapy in Patients with Stage II/III Rectal Cancer
High-level evidence supports adjuvant radiotherapy for rectal cancer. We examined the influence of sociodemographic factors on patterns of adjuvant radiotherapy for resected Stage II/III rectal cancer. Methods. Patients undergoing surgical resection for stage II/III rectal cancer were identified in SEER registry. Results. A total of 21,683 patients were identified. Majority of patients were mal...
متن کاملDosimetric Comparative Study of 3 Different Postoperative Radiotherapy Techniques (3D-CRT, IMRT, and RapidArc) for II–III Stage Rectal Cancer
Postoperative radiotherapy is critical for reducing local relapse for advanced rectal carcinoma but has many side effects. Our study compared the dose distribution of target volumes, protection of normal organs at risk (OAR), and monitor unit (MU) for 3 radiotherapy techniques (3-dimensional conformal radiation therapy [3D-CRT], intensity-modulated radiation therapy [IMRT], and RapidArc (Varian...
متن کاملRadiotherapy for rectal cancer: Short course versus long course – When and how
Prior to the introduction of improved surgical techniques such as total mesorectal excision, local recurrence rates after resection were unacceptably high with surgery alone. Phase III trials were designed to determine the benefit of the addition of radiotherapy to radical surgery, and these have reported significant reductions in local recurrence. Two different strategies were evaluated in the...
متن کاملRadiation therapy in stage II and III rectal cancer.
Over the past 25 years, significant advances have been made in the management of patients with rectal cancer. Phase III studies have shown the efficacy of postoperative radiation therapy and chemotherapy in improving local control and survival of patients with resected stage II and III disease.
