BACKGROUND In conservative breast surgery, the achievement of a satisfactory cosmetic result could be challenging; oncoplastic techniques may be helpful in many cases. A comparative analysis was performed among 3 groups of patients undergoing oncoplastic techniques plus external radiation therapy or intraoperative radiotherapy (IORT) and breast conservative surgery plus external radiation thera...

Background: Intraoperative radiation therapy (IORT) is a novel approach to breast cancer (BC) treatment. Objectives: In this study, we compared the cellular and molecular effects of IORT-treated post-lumpectomy wound fluid (seroma) at point IOeRT versus IOxRT on BC cell line. Methods: Immortalized human lines: MCF-7, MDA-MB-231, MCF10 were incubated with seroma from 3 groups patients (as pilot ...

BACKGROUND To date, there are no reports of intraoperative radiotherapy (IORT) use with long-term follow up as a method of accelerated partial breast irradiation (APBI) in Asian countries. We initiated a prospective phase I/II clinical trial of IORT in Japan in 2007, and herein, we report the 5-year follow-up results. MATERIALS AND METHODS The following inclusion criteria were used for enroll...

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...

BACKGROUND The Montpellier cancer institute phase II trial started in 2004 and evaluated the feasibility of intraoperative radiotherapy (IORT) technique given as a sole radiation treatment for patients with an excellent prognostic and very low recurrence risk. METHODS Forty-two patients were included between 2004 and 2007. Inclusion criteria were patients ≥ 65 years old, T0-T1, N0, ductal inv...

Intraoperative radiotherapy (IORT) refers to the delivery of a single radiation dose to a limited volume of tissue during a surgical procedure. A literature review was performed to analyze the role of IORT in gynaecological and genito-urinary cancer including endometrial, cervical, renal, bladder and prostate cancers.Literature search was performed by Pubmed and Scopus, using the words "intrao...

In patients with low-risk breast cancer, intraoperative radiotherapy (IORT) during breast-conserving surgery is a novel and convenient treatment option for delivering a single high dose of irradiation directly to the tumour bed. However, edema and fibrosis can develop after surgery and radiotherapy, which can subsequently impair quality of life. TGF- β is a strong inducer of the extracellular m...

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,...

RATIONALE AND OBJECTIVES To analyse the programme activity and clinical innovation and/or technology developed over a period of 17 years with regard to the introduction and the use of intraoperative radiotherapy (IORT) as a therapeutic component in a medical-surgical multidisciplinary cancer hospital. MATERIAL AND METHODS To standardise and record this procedure, the Radiation Oncology servic...

Two large randomised controlled trials of intraoperative radiotherapy (IORT) in breast-conserving surgery (TARGIT-A and ELIOT) have been published 14 years after their launch. Neither the TARGIT-A trial nor the ELIOT trial results have changed the current clinical practice for the use of IORT. The in-breast local recurrence rate (LRR) after IORT met the pre-specified non-inferiority margins in ...
