title: [The use of electrons in oncologic radiotherapy: our experience].
abstract: The authors describe the interaction of electrons with tissues, the characteristics of depth isodose curves with sharp dose fall-off. These characteristics reduce the utilization of electron therapy only for tumors situated some 5 cm depth below the skin surface and with regular surface. The authors report their experience from 1978 in the treatment of vulvar carcinoma, chest-wall recurrences from breast carcinoma, and cutaneous lymphomas. All these neoplastic diseases were treated with electron beam of adequate energy. Initially betatron was used, successively a linear accelerator (Siemens) about for two years. Results obtained in the treatment of vulvar carcinoma are reported. Two and five years disease free survival rates was respectively 33% and 19% (it is remarked the importance of prophylactic treatment on inguinal lymphnodes). Local control observed in 44 patients with cutaneous lymphomas was 85% until three years; a greater number of recurrences was observed in centrocytic-centroblastic lymphomas. Moreover, local control of breast recurrences was 65% with 5 years survival rate of 22% (34% in patients with only one skin recurrence). Only 22% of the further local failures appear within the treatment field while 78% appear out of field.
