Analysis of Long-term Results of Our Combination Therapy for Squamous Cell Cancer of the Maxillary Sinus.

Seventy-four patients between 1971 and 1982 in Period I and 32 patients between 1982 and 1987 in Period II with maxillary sinus squamous cell cancer were treated by combination therapy consisting of preoperative LINAC X-ray irradiation with 5-flourouracil intra-arterial chemotherapy followed by maxillectomy and primary reconstruction. In Period II, 21 patients received preoperative cisplatinum (CPPP) microcapsule chemoembolization and pepleomycin (PEP) i.m. and/or postoperative CDDP i.v. with PEP i.m. in addition to the combination therapy administered in Period I depending on systemic conditions, tumor stage and histopathological type. Five and 10-year crude survival rates were 68.9% and 55.4%, respectively, for Period I and 71.9% and 56.3% for Period II, with no significant difference between the two trials. In 21 selected patients in Period II, who had additional chemotherapy with preoperative CDDP chemoembolization and/or postoperative i.v. infusion of CDDP with pepleomycin i.m., 5 and 10-year survival rates were 85.7% and 61.9%, respectively.
