From RCJ11,

The CTC test was taken 1 week after she began weekly Herceptin & Abraxane infusions. The test showed NO ctc's. She will be given another test 4 weeks after beginning treatment & I will report results.

Can anyone explain this CTC test result so quickly after beginning new treatment when PET scan 1 week earlier showed significant progression? Is the test unreliable or unable to pick-up certain kinds of circulating cells? Please reply with any experiences having similar results or possible explanations.

Thanks
