Notas del editor
To summarise the efficacy data, the combination of first-line Herceptin ® plus docetaxel improved overall response rate, time to disease progression and median overall survival with statistical significance compared with docetaxel alone. Additionally, duration of response more than doubled from 5.1 to 11.4 months when Herceptin ® was added to docetaxel.
Median overall survival increased from 22.1 months in the docetaxel-alone arm to 30.5 months (p=0.0062) in the combination arm. This is a statistically significant difference and means that patients in the Herceptin ® plus docetaxel arm survived on average 8.4 months longer than those in the docetaxel-alone arm. This difference is seen despite the fact that approximately 48% of patients in the docetaxel arm crossed over to receive Herceptin ® at disease progression, which reduces the difference in survival seen between the two arms.
This is a reminder of the design IDMC have not so far suggested that detailed results of the 2 year arm should be released although we know that as for the 1 year arm, there ar significantly less events than in the Observation arm Following the ASCO 2005 results a protocol amendment was made to allow patients in the Observation arm to switch to Trastuzumab, irrespective of how long they had been in the trial since randomisation
DFS analysis with a median FU of 2 yrs, analysed by ITT- Continues to show a highly significant benefit for trastuzumab with a HR of 0.64 and an absolute DFS gain of 6.3% at 3 yrs Note the y axis goes from 0 to 100
The Overall S by ITT, which showed only a non-significant trend last year, now shows- a highly significant OS benefit for trastuzumab with a HR of 0.66 and a p of 0.0115 The absolute 3yr gain is 2.7%
