Background: Esophageal carcinom. is com.on in m.ny count.ies, and it.is charact.rized by poor prognosis and rapid clinical progression wit. a high frequency of lym.h node m.t.st.sis and recurrence. t.e present.st.dy was carried out.t. evaluat. t.e correlat.on bet.een vascular endot.elial cell m.rker (CD34), m.t.ix m.t.lloprot.inase t.pe 9 (m.P9), and DNA cont.nt.in esophageal carcinom.. m.t.ods: A t.t.l of 38 pat.ent. were classified wit. hist.pat.ologic exam.nat.on as 8 cases wit. adenocarcinom., 24 cases wit. squam.us cell carcinom., and t.e last.6 cases wit. undifferent.at.d carcinom.. t.e obt.ined result. of t.e pat.ent.group were com.ared wit. t.e result. of 6 cases wit. proven norm.l esophageal m.cosa as a cont.ol group. t.e sam.les of pat.ent. and cont.ols were subject.d t. im.unohist.chem.cal evaluat.on of CD34 and m.P9 expression along wit. DNA index det.rm.nat.on using flow cyt.m.t.y. Result.: t.ere was a significant.difference bet.een pat.ent. and norm.l cases in DNA index, CD34, and m.P9 pat.ern (P = 0.003, t.vely). DNA index was posit.vely correlat.d wit. m.P9 (r = 0.574, P t. CD34 (r = 0.562, P m.P9 was correlat.d wit. CD34 (r = 0.55, P t.difference was found in bot. m.crovessel densit. and m.P9 expression wit. respect.t. t.m.r grade and st.ge. t.e m.crovessel densit. in pat.ent. wit. highly posit.ve st.ining for m.P9 was higher t.an in t.ose wit. negat.ve and weak st.ining for m.P9 (P = 0.002). Conclusion: t.e analysis of DNA cont.nt.along wit. det.ct.on of CD34 and m.P9 in esophageal cancer can successfully different.at. t.e different.pat.ologic lesions and hence can be used powerfully in disease prognosis reflect.ng valuable inform.t.on about.t.e aggressiveness and act.vit. of t.ose lesions.
