Does concurrent chemoradiotherapy preceded by chemotherapy improve survival in locally advanced nasopharyngeal cancer patients? Experience from Ghana.

Abstract

Background: To find out how chemotherapy given prior to concurrent chemoradiotherapy compares with concurrent chemoradiation alone in the treatment of locally advanced nasopharyngeal cancer.

Methods: Patient charts were examined and found to have submitted to one of two regimes as follows: Neoadjuvant chemotherapy consisting of Cisplatin and 5-fluorouracil followed by concurrent chemoradiotherapy with cisplatin (group1), or concurrent cisplatin based chemoradiotherapy only (group 2). Radiation treatment dose of 70Gy in 35 fractions was given in each group.

Results: Forty-seven patients were evaluated with 68% male. Stage 4 disease comprised 83%, WHO type 3 was the commonest histologic type (53.2%). Median follow up period was 20 months (4-129). The 3-year overall survival for group 1 was 52.1%, and for group 2:65.7% (p = 0.47). The 3-year disease free survival for group 1 was 61.4, and 81.4% for group 2 (p = 0.03).

Conclusion: The study revealed that concurrent chemoradiation alone yields better disease free survival compared to chemotherapy given prior to it. There is however no difference in overall survival between the two regimes.
