Pancreatic adenocarcinoma is the second most common gastrointestinal malignancy and the fourth leading cause of cancer mortality in the United States [1]. Both local and systemic therapies are integral in the treatment of pancreatic cancer. Aggressive local treatment leads to improved local control which can translate into improved overall survival [2]. For patients with locally advanced pancre...
Intraoperative radiation therapy in breast cancer (IORT) delivers a concentrated dose of radiation therapy to a tumor bed during surgery. IORT offers some of the following advantages with typically fewer complications like; maximum effect, sparing healthy tissues and organs, to help the patients finish treatment and get back to their normal activities. The goal of IORT is to improve local tumor...
Background and purpose: Among different cancers, breast cancer has a high prevalence among women and radiotherapy is used as a treatment modality in which radio sensitizers are used to increase its efficiency. Nanoparticles are such sensitizers that enhance the efficiency of radiotherapy via creation of free radicals and induction of oxidative stress. This study aimed at evaluating the synergis...
PURPOSE To analyze the outcomes of patients from a single institution treated with surgery and orthovoltage intraoperative radiotherapy (IORT) for pancreatic adenocarcinoma. METHODS We retrospectively reviewed 23 consecutive patients from 1990-2001 treated with IORT to 23 discrete sites with median and mean follow up of 6.5 and 21 months, respectively. Most tumors were located in the head of ...
HYPOTHESIS Despite aggressive approaches, locoregional tumor control and survival rates for patients with cancer of the pancreatic head remain disappointing. In the present study, we address whether intraoperative and adjuvant radiotherapy may improve the prognosis for these patients. DESIGN A retrospective study. SETTING University hospital. PATIENTS From February 1985 to December 1995, ...
