[Postoperative treatment of malignant tumors of the parotid gland: radiotherapy, concomitant chemotherapy and radiation therapy?].

The low incidence, the wide histological spectrum and the natural, sometimes slow, evolution of malignant parotid gland tumours do not allow to easily establish the impact of their treatments. At present, clinical data come from retrospective cohort analysis, whereas randomized phase II-III trials are confidential. Moreover conclusions from these studies are controversial. We present here the therapeutic highlights of parotid cancers: surgery, with the particular concern of facial nerve preservation; and adjuvant treatment essentially based on radiotherapy. This review focused on adjuvant care explores the indications and the technical aspects of radiation, as well as the role of concurrent chemotherapy.
