Concurrent chemoradiotherapy with carboplatin followed by carboplatin and 5-fluorouracil in locally advanced nasopharyngeal carcinoma.

BACKGROUND: This study aimed to evaluate acute major toxicities, the response rate, 3-year overall survival and progression-free survival rate of locally advanced nasopharyngeal carcinoma patients on concurrent carboplatin chemoradiotherapy followed by carboplatin and 5-fluorouracil.

METHODS: A prospective study of fifty patients diagnosed with locally advanced nasopharyngeal carcinoma received conventional radiation therapy with a total dose of 6600-7000 cGy in 6-7 weeks and concurrent chemotherapy of three cycles of carboplatin during radiotherapy, followed by adjuvant chemotherapy using carboplatin plus 5-fluorouracil for two cycles.

RESULTS: Weight loss and mucositis were the two most common acute major grades 3-4 toxicities (42%). Myelosuppression occurred subsequently, including leukopenia (30%), neutropenia (20%), anemia (12%), and thrombocytopenia (6%). Only 8% of patients developed grades 3-4 nausea and vomiting. No patients had renal and electrolyte abnormalities. Regarding the response evaluation, 100% of patients achieved an objective response rate of the primary tumor (92% complete response, and 8% partial response). Similarly, all patients also achieved an objective response rate of the neck node (64% complete response and 36% partial response). The 3-year overall survival rate and progression-free survival rate were 89.7% and 72.7%, respectively.

CONCLUSIONS: Concurrent chemoradiotherapy with carboplatin followed by carboplatin and 5- fluorouracil could be considered as an alternative regimen for locally advanced nasopharyngeal carcinoma patients pertaining to a good overall response rate, 3-year overall survival and progression-free survival rate with good tolerability.
