I presume some kind of animal testing?&lt;p&gt;Seems pretty immoral to give someone a wildcard treatment and not back it up with something known to work. Not disparaging this treatment but given we don&amp;#x27;t know if it works yet (and how aggressive cancer can be) it seems totally fair to administer it alongside chemo.</text><parent_chain></parent_chain></comment><story><title>Two Infants Treated with Universal Immune Cells Have Their Cancer Vanish</title><url>https://www.technologyreview.com/s/603502/two-infants-treated-with-universal-immune-cells-have-their-cancer-vanish/</url></story>

As a point of interest, this type of engineered T-cell treatment has its roots in research at the Weizmann Institute in Tel Aviv.  They demonstrated the use of CARs modified T-cells in curing leukemic disease in rats and mice several years ago.&lt;p&gt;Their research was expanded to human trials at Univ. of Penn. where 27 of 29 patients with incurable leukemia and most of whom had a prognosis of death within a few months went into remission and showed no sign of the disease.&lt;p&gt;This modality may work with other forms of cancer; engineered T-cells that can enter every capillary in the body could potentially wipe out entire colonies of cancer cells.  The potential is enormous, as are the challenges; cancers can be very difficult to differentiate from healthy tissue.&lt;p&gt;[1]&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.timesofisrael.com&amp;#x2F;breakthrough-cancer-cure-has-deep-israeli-roots&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.timesofisrael.com&amp;#x2F;breakthrough-cancer-cure-has-de...&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Two Infants Treated with Universal Immune Cells Have Their Cancer Vanish</title><url>https://www.technologyreview.com/s/603502/two-infants-treated-with-universal-immune-cells-have-their-cancer-vanish/</url></story>
