Evidence for viral infection in cancer patients: correlation with viral dose. Onyx-015 replication postinfection was measured on day 4 indirectly as described in the legend (Panel A). SCH58500 rAd.p53 gene expression was measured using RT-PCR on biopsies obtained at laparotomy 2–7 days post-HAI (Panel B). The dose at which biological activity was reproducibly seen was similar in the two trials.
