[Retrospective appreciation of results of treatment and early and late radiologic mucositis and other postradiological complications in patients with parotid gland cancer irradiated postoperatively].
We describe results and complications of combined (surgery and radiotherapy) treatment of parotid gland cancer. 86 patients, 31 women and 55 men, have been treated between the years 1984-1997 in Cancer Center--Institute in Warsaw. Mean age of patients was 56.6 years and ranged from 15 to 84 years. Surgical treatment was microscopically radical in 16 patients, macroscopically radical in 59 patients and debulking was performed on 11 patients. 5-year overall survival has been estimated as 58.2%. Distant metastases were observed in 23.3% of patients, local recurrences were observed in 12.8% of patients. Late serious postirradiation skin reaction (grade IV EORTC) was observed 6 months after completion of radiotherapy in 1 patient, and symptoms subsided completely during next 18 months. Late mucosal postirradiation complications (grade I and II EORTC) after 6 to 8 months after radiotherapy were described in 22.9% of patients and after 24-26 months in 15.9% of patients. There were no serious--grade III and IV EORTC--mucosal complications. Observed xerostomia was minimal due to compensation of saliva production by contralateral major salivary glands and did not worsen patients quality of life. Early middle ear postradiological inflammation occurred in 18.6% of patients, late reaction in the middle ear (6 to 8 months after completion of radiotherapy) was observed in 19% of all patients. In the group of 57 patients who survived 2 years after radiotherapy 1 developed temporo-mandibular joint fibrosis. Late postradiological changes in petrosal bone were detected in 2 patients (1 in Rtg imaging and 1 in CT imaging)-they were painful and primarily suspected as recurrence. None of the patients had clinically overt temporal lobe complications. Our patients survival results were a little worse than reported in the literature. Observed tolerance of combined treatment was very good.
