N2 - Treatment of Nasopharyngeal Carcinoma (NPC) has been based on the Intergroup 0999 trial with chemoradiation (CRT) and consolidation chemotherapy (CT). While effective, toxicities are significant. As a result, many oncologists use induction chemotherapy (IC) followed by CRT, citing better tolerance with anecdotally no worse outcome. We reviewed 95 NPC patients treated between 2005 and 2015 at MDACC with IC followed by CRT. Median age was 49 years. Fifty-seven were T3/T4 and 62 were N2-3. The most common IC regimen was a platinum-taxane doublet (N = 72). 83 patients completed IC. Grade 3–4 toxicities with IC occurred in 10 patients. There were 15 primary site complete responses (CR), 68 partial responses (PR),6 stable disease (SD), and 2 progressed. There were 10 nodal CR, 73 PR, 4 SD, and 3 progressed. 92 patients received RT, 74 with CRT. At completion of treatment, there were 81 CR and 8 PR patients. Post radiation toxicities included mucositis and skin rash (37), oto- toxicity (25), PEG placement (12), and osteonecrosis (2). Three-year progression free survival (PFS) and distant metastasis free survival (DMFS) were 77.3% and 78%. CRT for advanced NPC is standard, but IC remains controversial. Early trials failed to show a benefit but used older chemotherapy and pre-intensity modulated radiation therapy (IMRT) methods. Modern trials with platinum-taxane regimens and IMRT have shown reasonable PFS and OS results with acceptable toxicity. This retrospective review of IC followed by CRT showed acceptable toxicity and good response and survival outcomes. This approach has, for many oncologists, become a standard.
