However, in the two cisplatin-based concurrent chemoradiation studies (RTOG 0129 and 0522), the elderly patients experienced significantly more grade 3–5 thrombocytopenia ( p = 0.02), anemia ( p = 0.03), nephrotoxicity ( p = 0.01), and ototoxicity (borderline significant; p = 0.06) than the younger patients, whereas surprisingly, severe mucositis occurred significantly less frequently in the elderly patients ( p = 0.04).
