BACKGROUND: To compare the survival outcomes and acute toxicities of concurrent
chemoradiotherapy (CCRT), induction chemotherapy (IC) plus radiotherapy (RT), and
IC plus CCRT in patients with locoregionally advanced nasopharyngeal carcinoma
(NPC) treated using intensity-modulated radiotherapy (IMRT). METHODS: Patients
with stage III-IVB NPC who were treated with IMRT between 2009 and 2012 at a
single institution were retrospectively reviewed. The induction regimens included
PF (cisplatin and fluorouracil) and TP (docetaxel and cisplatin) every 3 weeks
for 2-3 cycles; the concurrent regimen was cisplatin every three weeks for 2-3
cycles. A propensity score matching method was used to match patients from each
group in a 1:1:1 ratio. RESULTS: In total, 147 eligible patients were
propensity-matched, with 49 patients in each treatment group. The median
follow-up duration was 38.5 months (range, 4.5 - 56 months). The 3-year
disease-free survival, overall survival, distant metastasis-free survival, and
locoregional relapse-free survival rates were 82.1%, 92.8%, 87%, and 90.4% in the
CCRT group; 86.3%, 91.0%, 91.6%, and 94.4% in the IC plus RT group; and 87.8%,
95.8%, 93.8%, and 93.9% in the IC plus CCRT group, respectively. No statistically
significant survival differences were observed between the three treatment groups
in either univariate or multivariate analyses. The incidence of grade 3-4 acute
toxicities was similar among groups. CONCLUSIONS: This study suggests that CCRT,
IC plus RT, and IC plus CCRT are similarly efficacious treatment strategies for
patients with locoregionally advanced NPC treated using IMRT; however, long-term,
large-scale randomized trials are required to confirm these findings.
