Table 3. Response to Trastuzumab-based therapy according to BiotHER status.
Response | BiotHER pos. | Rate (%)a | BiotHER neg. | Rate (%) |
---|---|---|---|---|
CR+PR | 24 | 89b | 16 | 59 |
CR | 2 | 7 | 4 | 15 |
PR | 22 | 81 | 12 | 44 |
SD | 2 | 7 | 9 | 33 |
PD | 1 | 4 | 2 | 7 |
Because of rounding, the sum of percentages is not always=100.
Fisher's exact test for the difference in the rate of responders (CR+PR), P=0.03.
CR=complete remission; PR=partial remission; SD=stable disease ; PD=progressive disease.
