Background: The majority of patients with head and neck cancer are treated with concurrent chemoradiotherapy. However, toxicity is substantial so that alternate schedules of cisplatin have been tried to overcome this problem. No formal comparison, however, has been reported between alternate schedules and reference regimen.
Patients and methods: Fifty-five eligible patients treated with concurrent chemoradiotherapy were retrospectively analyzed. The patients treated with weekly cisplatin were defined as group A, while the patients treated with standard regimen were defined as group B. Basic demographics and clinical characteristics', overall survival rate, locoregional or systemic relapse rates, and time to local/systemic relapse were recorded.
Results: One, two, and three-year probability of survival in groups A and B were 75% to 65% after one year, 63% to 56%after two, and 63% to 52% after three, respectively. Although time to local and systemic relapse was higher in group B as compared to group A, a statistical analysis was failed to show any significant difference. Furthermore, there was no significant difference between groups with respect to major toxicity.
Conclusion: In patients with head and neck cancer, concurrent chemoradiotherapy with weekly cisplatin might be as effective as concurrent chemoradiotherapy with bolus cisplatin.
