[Peroperative radiotherapy. Initial experience at the Red Cross Hospital].

Intra operative radiation therapy is a new look at an old idea (Rich). In relation with the first experience at the Croix-Rousse Hospital with orthovoltage, a review of technical choices, surgical problems, and biological questions is presented. The analysis of literature about accumulated clinical results suggest that local control in recurrence, residual, or inoperable tumor can be obtained by combined surgery IOR, and external beam irradiation.
