Table 3. Infection rate head and neck cancer patients treated with different treatment modality.
Variables | Infection event | Infection rate | P-value* |
With cetuximab (n = 158) | 0.581 | ||
Surgery+Chemotherapy+Radiotherapy (n = 76) | 14 | 18.4 | |
Chemotherapy/Chemotherapy+Radiotherapy (n = 82) | 18 | 22.0 | |
Without cetuximab (n = 925) | 0.261 | ||
Surgery+Chemotherapy+Radiotherapy(n = 486) | 54 | 11.1 | |
Chemotherapy/Chemotherapy+Radiotherapy(n = 439) | 39 | 8.9 |
P value of Pearson’s chi-square test between the cetuximab group v.s without cetuximab group is <0.001.
