Summary

Twenty-four patients with maxillary squamous cell carcinoma were treated with 50 μg of phytohemagglutinin (PHA), saturated into pieces of gelatin sponge, and applied to the maxillary sinus which was in advance surgically exposed via the peroral route. Treatment was combined with cobalt 60 irradiation at 4,000 rads (200 rads×20 doses over a one month period) and concurrent arterial infusion of 5-fluorouracil (5-FU) with a total dosage of 5,000 mg (250 mg× 20 doses). After 20 treatments with phytohemagglutinin, gross examination showed that tumors were no longer apparent in 83.3% of the cases treated with PHA vs. 52.6% in the control group without PHA. On histological examination, 66.6% in the PHA group showed no signs of tumors vs. 15.8% in the control group. Microscopically, the disappearance of the tumors was frequently observed in tumor of T2 more than that of T3 in extent of primary tumor. No side effects were observed nor was there a significant difference between the control group and the PHA group in the 3-year crude survival rate (control group: 68.4%; PHA group: 62.5%)

Zusammenfassung

Behandlung von 24 Patienten mit einem Plattenepithelkarzinom der Kieferhöhle mit 50 μg Phytohaemagglutinin (PHA). Das Präparat wurde mittels Gelita in die peroral eröffnete Kieferhöhle eingebracht und die Therapie mit einer Telekobaltbestrahlung von 4000 rad (20×200 rad über einen Monat) sowie arteriellen Infusionen von 5-Fluorouracil (5-FU), 20×250 mg, kombiniert. Nach 20 Behandlungen mit PHA war der Tumor in 83,3% der Fälle verschwunden, während er bei den Patienten ohne PHA-Therapie nur in 62,6% nicht mehr nachzuweisen war. Bei der histologischen Untersuchung fand sich in der PHA-Gruppe in 66,6% kein Tumor mehr, bei der Gruppe ohne PHA dagegen nur in 15,8%. Nebenwirkungen wurden nicht beobachtet. In der 3 Jahre-Überlebensrate bestand zwischen beiden Gruppen kein signifikanter Unterschied.
