چکیده

BACKGROUND We aimed to compare the long-term survival outcomes and acute toxicity of cisplatin administered weekly versus every three weeks concurrently with intensity-modulated radiotherapy (IMRT) in patients with nasopharyngeal carcinoma (NPC). METHODS This was a retrospective review of 154 patients with histologically proven, non-disseminated NPC who were treated using IMRT between January 2003 and December 2007. Seventy-three patients (47.4%) received 5-7 weeks of 30-40 mg/m2 cisplatin weekly; 81 patients (52.6%) received two or three cycles of 80 mg/m2 cisplatin every three weeks. IMRT was delivered at 68 Gy/30 fractions to the nasopharyngeal gross target volume and 60-66 Gy to the involved neck area. RESULTS The clinical characteristics and treatment factors of the two groups were well-balanced. The median follow-up was 74 months (range, 6-123 months), and the 5-year overall survival, disease-free survival, locoregional relapse-free survival, and distant metastasis-free survival rates were 85.2% vs. 78.9% (P = 0.318), 71.6% vs. 71.0% (P = 0.847), 93.5% vs. 92.6% (P = 0.904), and 80.9% vs. 80.1% (P = 0.925) for the group treated every three weeks and weekly, respectively. Subgroup analyses indicated no significant differences in the survival rates of the two groups among patients with early- or advanced-stage disease. The incidence of acute toxicities was similar between groups. CONCLUSION IMRT with concurrent cisplatin administered weekly or every three weeks leads to similar long-term survival outcomes and acute toxicity in NPC regardless of whether patients have early- or advanced-stage disease.

Addition of 5-fluorouracil to first-line induction chemotherapy with docetaxel and cisplatin before concurrent chemoradiotherapy does not improve survival in locoregionally advanced nasopharyngeal carcinoma

Although a multicenter, randomized study indicated that induction chemotherapy (IC) with docetaxel/cisplatin/fluorouracil (TPF) before concurrent chemoradiotherapy (CCRT) improves survival outcomes, it remains unclear whether TPF is the best IC regimen for treating locoregionally advanced nasopharyngeal carcinoma (NPC). Our aim was to compare the efficacy and toxicities of TPF vs. docetaxel/cis...
