“…There have been many reports on the role of surgical excision alone or followed by adjuvant radiotherapy (Abbas et al, 1981;Coe et al, 1981;Dewar & Duncan, 1985;Markhede et al, 1982;Ueda et al, 1988). A poor survival in patients with unresectable tumours, irrespective of further treatment has been shown by Suit et al (1985) and Gerner et al (1975). Various methods of surgical treatment seem to relate to different rates of local recurrence (Markhede et al, 1982;Shieber et al, 1961;Shiu et al, 1975); this may be simply a reflection of the inadequacy of surgical excision (Abbas et al, 1981;Bell et al, 1989;Collin et al, 1987;Mandard et al, 1989).…”
