CA. OF THE OROPHARYNX INCIDENCE OF OCCULT NODES Base of Tongue 50-60% Tonsil & Tonsillar Fossa 50-60% Soft Palate 20-30% Anterior Pillar 10-15%
Oropharyngeal CA:Treatment Volume (Nathu et al. Univ of Florida, 2000) • 1983-1985; N=114; T2-4 SCC Tonsil Tonsil, BOT BOT, Soft Palate • Definitive RT+/- brachy; 12 pts had induction chemo • Dose ranged from 50.4 50 4 to 81.6 81 6 Gy / 1.2 1 2 Gy BID +/- +/ 10 10- 15 Gy of brachy boost; 16 pts had QD RT with median dose of 70 Gy • All had pretx CT scan to determine volume and subsequently q y underwent CT tx planning p g • Multivariate analysis showed that local control rate correlated with T-stage but did not correlate with tumor volume within a given T-stage
