The squamous cell carcinoma needs to be removed surgically. Depending on the extent of metastasis, perhaps arming the Listeria with the "Rhenium-188, a radionuclide that kills cells by releasing DNA-damaging radiation and has shown promising results in a handful of early stage trials against a variety of cancers. Sure enough, regular injections of Rhenium-188-labeled L. monocytogenes decreased metastases by 90 percent over saline-injected mice."
If this option was available, then I would consider it along with the SURGERY. ADXS is really losing out..and you guys will certainly be picking up the tab here.
