What do they mean by "for a time?" I just the cancer wasn't cured. Too bad.
The original cancer (with given marker) that the reengineered T cells ( immune cells )were designed to kill, the T cells did a fabulous job of eliminating them. In 8 months that cancer had vanished. But then the cancer reappeared without the marker and the T cells could no longer identify them as a target so they grew. Their next approach will be to target multiple markers on the tumor so if one target drops the T cells will continue to fire away at the tumor using other targets. The significance of this trial is that it established proof concept that reengineered immune cells work not just against blood cancers (aka liquid cancers) but against solid tumors as well. That is yuuuge.
