Abstract
The production of prostaglandin E ex vivo was studied in samples of 31 squamous cell carcinomas of the head and neck (SCCHN) and 12 adenocarcinomas of gastrointestinal tract (ACGI). As a control, the PGE production was measured in 22 samples of noninvolved mucosa in patients with SCCHN and 12 samples of gastrointestinal mucosas. The mean PGE production by SCCHN was significantly higher than in normal mucosa. Furthermore, the PGE production by tumors which recurred or spread to regional lymph node within 18 months after surgery was higher than in tumors which did not recur within that interval. Also, production of PGE by noninvolved mucosa was significantly higher in patients in which tumor recurred after surgery than in patients which were tumor free. On the other hand, the mean production of PGE by ACGI was not different from that of normal mucosa. These data show that determination of PGE production might have prognostic significance in SCCHN.
