We investigated whether intraoperative radiotherapy (IORT) during curative surgery for esophageal carcinoma is useful or not. The cases of 117 patients diagnosed with thoracoabdominal esophageal carcinoma who underwent curative surgery between 1986 and 2007 were reviewed: 72 patients received IORT (IORT group) and 45 did not (non-IORT group). Upper abdominal lymphadenectomy was performed in 115...

Intraoperative radiotherapy (IORT) consists of an accelerated, single-dose, partial breast irradiation, performed immediately after breast conservative surgery. In the present study, we report the results of our feasibility protocol study using IORT between 2005 and 2009. We analyzed the data from a single-center, open, non-randomized, prospective pilot study including patients who underwent br...

Intraoperative radiotherapy (IORT) involves the administration of therapeutic radiation to malignancies during surgical procedures. IORT permits high dose delivery to tumors with the simultaneous reduction of radiation exposure to normal tissues, which may be directly shielded or operatively mobilized from the treatment volume. IORT has been investigated in various intra-abdominal malignancies,...

High-dose-rate intraoperative radiation therapy (HDR-IORT) has historically provided effective local control (LC) for patients with unresectable and recurrent tumors. However, IORT is limited to only a few specialized institutions and it can be difficult to initiate an HDR-IORT program. Herein, we provide a brief overview on how to initiate and implement an HDR-IORT program for a selected group...

Purpose Intraoperative radiation therapy (IORT), delivered by intraoperative electron beam (IOERT) or high-dose-rate brachytherapy (HDR-IORT), may reduce the local recurrence rate in patients with locally advanced and recurrent rectal cancer (LARC LRRC, respectively). The aim of this study was to compare oncological outcomes between both IORT modalities LARC LRRC who underwent a microscopic irr...

Background/aim: Intraoperative radiation therapy (IORT) may pose a risk for wound complications. All technical aspects of IORT regarding early wound complications were evaluated. Materials and methods: Ninety-three consecutive patients operated on with the same surgical technique and given (study group) or not given (control group) IORT were included. Wound complications were evaluated in two g...

The advent of mobile LINACs for use in intraoperative radiation therapy (IORT) promises to make IORT more accessible than before and easier to deliver to patients undergoing surgery. Although mobile IORT systems have been available since 1999, few treatment centers currently use them. Here, we present the case of a typical patient undergoing IORT for retroperitoneal sarcoma to show how easy the...

Intraoperative radiotherapy (IORT) for early stage breast cancer is a technique for partial breast irradiation. There are several technologies in clinical use to perform breast IORT. Regardless of technique, IORT generally refers to the delivery of a single dose of radiation to the periphery of the tumor bed in the immediate intraoperative time frame, although some protocols have performed IORT...

PURPOSE Although intraoperative radiotherapy (IORT) is known to be a method that can reduce local recurrence in locally advanced colorectal cancer, it is not widely used. The aim of this study was to report our experience with IORT for locally advanced rectal cancer. METHODS From 1991 to 1994, nine patients with locally advanced rectal cancer received IORT. External beam radiotherapy was give...

The use of intraoperative radiation therapy (IORT) is increasing with the development of new devices for patient treatment that allow irradiation without the need to move the patient from the surgical table. At the moment, ionizing radiation in the course of IORT is supported most often by the use of mobile devices that produce electrons, kilo voltage X-rays, and electronic brachytherapy and th...
