1. Estudo comparativo dos achados mamográficos após radioterapia intra-operatória com feixe de elétrons (IORT) e radioterapia externa (RT) em pacientes com câncer de mama em estádio inicial submetidas a tratamento conservador / Mammography findings following IORT or RT for breast cancer treatment
O tratamento conservador do câncer de mama é hoje uma realidade em pacientes com estádio inicial da doença. Estudos randomizados demonstraram a importância da radioterapia após a cirurgia conservadora do câncer de mama. A radioterapia externa (RT) envolve 5 a 6 semanas de radioterapia com uma dose total de 50Gy, e um reforço de 10Gy no leito cirúrgi

2. Monte Carlo simulation as an auxiliary tool for electron beam quality specification for intra-operative radiotherapy
Intra-operative radiotherapy (IORT) using electron beams has demonstrated to be a good alternative as part of the breast-conserving surgery. Besides, as the computer processing capacity has been increasing along the years, it has become a potential auxiliary tool in radiotherapy treatment planning. In this work these streams are merged together: simulations

3. Intraoperative radiation therapy following pancreaticoduodenectomy.
OBJECTIVE: To determine the morbidity and mortality of pancreaticoduodenectomy followed by electron-beam intraoperative radiation therapy (EB-IORT). SUMMARY BACKGROUND DATA: Local recurrence following pancreaticoduodenectomy occurs in 50% to 90% of patients who undergo a potentially curative surgical resection for adenocarcinoma of the pancreatic head. To im

4. Intraoperative electron beam irradiation for patients with unresectable pancreatic carcinoma.
Since 1978 we have used electron beam intraoperative radiation therapy (IORT) to deliver higher radiation doses to pancreatic tumors than are possible with external beam techniques while minimizing the dose to the surrounding normal tissues. Twenty-nine patients with localized, unresectable, pancreatic carcinoma were treated by electron beam IORT in combinat

5. Pancreatic resection combined with intraoperative radiation therapy for pancreatic cancer.
OBJECTIVE: The objective of the study was to analyze a single center's experience in the treatment of pancreatic carcinoma with a combination of pancreatic resection and intraoperative radiation therapy (IORT). SUMMARY BACKGROUND DATA: Pancreatic cancer is the most lethal form of gastrointestinal malignancy. Historically, it carries a 20% 1-year survival and

6. Analysis of failure after curative irradiation of extrahepatic bile duct carcinoma.
Thirty-four patients with subtotally resected or unresectable carcinoma of the extrahepatic bile ducts received radiation therapy; a minimum of 45 Gy (external beam) to the tumor and regional lymph nodes +/- 5-fluorouracil (5-FU). Seventeen patients received an external beam boost of 5 to 15 Gy to the tumor, and a specialized boost was used in the remaining

8. Preoperative infusional chemoradiation, selective intraoperative radiation, and resection for locally advanced pelvic recurrence of colorectal adenocarcinoma.
OBJECTIVE: The results of preoperative infusional chemoradiation, resection, and selective intraoperative radiation (IORT) boost in 43 previously nonirradiated patients with locally advanced pelvic recurrence of colorectal adenocarcinoma are described. SUMMARY BACKGROUND DATA: After surgery alone 10% to 30% of patients with carcinoma of the distal colon and
