title: [Results of photon therapy of malignant tumors of the parotid gland].
abstract: Between 1971 and 1982 86 patients have been treated because of a malignant tumor of the parotid gland. 64 patients have been irradiated after complete (n = 49) or incomplete (n = 15) first resection. 12/64 (19%) relapsed locally. The loco-regional tumor control rate five and ten years after postoperative radiotherapy is 72%, 85% after complete resection, and 22% after incomplete resection (p less than 0.01). Tumor size and nodal disease are of prognostic value. Disease-free survival in patients without lymph nodes is 53%, with lymph node metastases 31% after five years (p less than 0.05). Small tumors (T1, 2) have a better local control rate compared to locally advanced tumors (five years: 83% vs. 53%, p less than 0.05). No difference was found neither for the total dose nor the histology of the tumor. Distant metastases became apparent after median eleven months.
