Remodelling of Extracellular Matrix in Rectal Cancer and Preoperative Radiotherapy
BACKGROUND Preoperative radiotherapy reduces local recurrence due to rectal cancer, but increases postoperative morbidity. The aim of this thesis was to study the impact of radiotherapy on extracellular matrix (ECM) remodelling enzymes and growth factors after radiotherapy and also their possible use as surrogate markers for complications. A secondary aim was to explore the use of these enzymes...
متن کاملPreoperative UFT and calcium folinate and radiotherapy in rectal cancer.
Protracted infusions of 5-fluorouracil (5-FU) combined with pelvic radiotherapy have been associated with improved survival and decreased local and distant metastases in the adjuvant therapy of rectal cancer. However, this method of 5-FU infusion requires the inconvenience and expense of central venous line placement and care, infusion pumps, and treatment of catheter-related complications. We ...
متن کاملImproved survival with preoperative radiotherapy in resectable rectal cancer.
BACKGROUND Adjuvant radiotherapy for rectal cancer has been extensively studied, but no trial has unequivocally demonstrated improved overall survival with radiotherapy, despite a reduction in the rate of local recurrence. METHODS Between March 1987 and February 1990, we randomly assigned 1168 patients younger than 80 years of age who had resectable rectal cancer to undergo preoperative irrad...
متن کاملCost-effectiveness of preoperative radiotherapy in rectal cancer: results from the Swedish Rectal Cancer Trial.
PURPOSE The Swedish Rectal Cancer Trial (SRCT) demonstrated that a short-term regimen of high-dose fractionated preoperative radiotherapy (5 x 5 Gy) reduced the local recurrence rates and improved overall survival. This has had an impact on the primary treatment of rectal cancer. The current study investigated the cost-effectiveness of the new combined approach. METHODS AND MATERIALS After an...
متن کاملAn Update on Preoperative Radiotherapy for Locally Advanced Rectal Cancer
Even in patients undergoing an optimal surgical technique (e.g., total mesorectal excision), radiotherapy provides a significant benefit in the local control of rectal cancer. Compared with postoperative treatment, chemoradiotherapy given preoperatively has been shown to decrease local recurrence rates and toxicity. Additionally, preoperative chemoradiotherapy permits the early identification o...
