Abstract

Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3 T1, 16 T2, 32 T3, and 22 4. Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but three patients received 50–60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation was not routinely given. Clinically involved nodes were treated with definitive radiotherapy (five patients) or combined treatment (one patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 % The overall local control rate was 78 %. Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without elective neck treatment was 38% for squamous and undifferentiated carcinoma, and only 5% for adenoid cystic carcinomas. Therefore, our current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T1 lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis.

      In our study, 59 patients (all with SCC, 37% of whom had unresectable disease) were treated with particle therapy alone; the 5-year OS, PFS, and LC rates were 41.6%, 34.7%, and 50.4%, respectively. These results are comparable with those in previous studies (Table 5) (5, 6, 8-17). In a study by Hoppe et al (11) of 85 patients (49% with SCC) treated with surgery followed by photon therapy, the 5-year OS and LC rates were 67% and 62%, respectively.
