SANTINI B, Alejandro et al. RADIOTERAPIA LUMBOAÓRTICA EN PACIENTES CON CÁNCER DE CUELLO UTERINO: EXPERIENCIA DEL INSTITUTO NACIONAL DEL CÁNCER. Rev. chil. obstet. ginecol. [online]. 2010, vol.75, n.1, pp.9-16. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262010000100003.

Background: Uterine cancer is still a prevalent disease in Chile. Is common to treat patients with tumors in stages IIB and IIIB where the risk of pelvic and paraortic limph node involvement is very high. Its treatment is radio-chemotherapy. Objective: To present a retrospective analysis of patients that suffered cervix-uterine cancer who were treated with radiotherapy including the aortic-lumbar area. Methods: From the revision of patients who were treated of cervix-uterine cancer between the years 1995 and 2007, 39 were treated including aortic-lumbar chains. Evolution and toxicity were analyzed. Two radiotherapy techniques were used. The first one, during the nineties, included two parallel previous and later and opposed fields, and a second technique, currently used, where pelvis and paraortic are radiated at the same time through four lateral (AP-PA) fields. Results: The dosimeter analysis of both techniques shows that there is a higher volume of radiated normal tissue with the two fields techniques, mainly in the small bowel. On the other hand, the toxicity was significantly different being today's technique less toxic and showing low gastrointestinal side effects, despite receiving a simultaneous radio-chemotherapy (55% vs 0%). Conclusion: The paraortic radiotherapy treatment has an acceptable level of tolerance even under simultaneous radio-chemotherapy. Given the results of this study, we see the need for undergoing a new research project in order to evaluate if the aortic-lumbar radiotherapy may reduce the risk of relapse and increase in survival rate.
