- The addition of induction chemotherapy (IC) to concurrent chemoradiotherapy (CCRT) is associated with similar survival outcomes to CCRT alone in patients with stage II nasopharyngeal carcinoma (NPC).
Why this matters
- A previous study using a smaller sample size had shown negative effects on survival with IC, but in this study the treatment regimen is not significantly associated with survival.
- 5-year DFS was 85.1% and 5-year OS was 93.2%.
- CCRT with IC was associated with a lower 5-year DFS (80.6% vs 88.5%) rate compared with CCRT alone, although this difference was not significant in multivariate analysis (HR, 1.047; P=.057).
- CCRT with IC was associated with similar 5-year OS compared with CCRT alone (90.5% vs 95.0%; P=.375).
- Adding IC to CCRT was associated with higher incidence of grade 3/4 hematological toxic effects (23.6% vs 6.4%; P<.001 grade liver dysfunction vs p and kidney compared with ccrt alone.>
- 445 patients with stage II NPC, 195 treated with IC and CCRT and 250 treated with CCRT alone, were analyzed.
