[Intraoperative radiotherapy (IORT) at the Graz University Clinics: results of a pilot study on non-small cell lung carcinoma].
A pilot study was undertaken during which 15 patients with non-small cell pulmonary carcinomas were exposed to an intraoperative irradiation; twelve out of them were submitted to an additional percutaneous photon therapy. The criteria used to select these patients were functional inoperability, exclusion of remote metastases, and a Karnofsky index greater than 70. Central and peripheral tumors of the stages T1-3, N0-2 were included into the study after histological confirmation of the diagnosis. The local regression rate of the primary tumor can be assessed quite well despite the short follow-up time of 4.5 to 16 months (10 months on an average) which does not yet allow to make a conclusion as to a prolongation of the disease-free survival time. Already two months after the end of external irradiation, a complete remission (CR) was seen in three patients (25%), a partial remission (PR) in seven patients (67%), and a minor remission (MR) in one patient. In the course of further follow-up, the number of complete remissions increased to six (50%). We are encouraged by the small morbidity and a therapeutic response higher than average to continue with this therapy method in patients who, for the time being, are still selected according to strict criteria.
