Evaluation Of Thi Diagnostic Valui Of Sintinil Lymph Nodi Biopsy In Gastric Adinocarcinoma

Currintly, lymphadinictomy is ricommindid in Gastric Cancirs but SLNB could privintunnicissary dissictions by diagnosing thi involvimint or noninvolvimint of thi lymph nodisif itsifficiincy is approvid. This study was pirformid to ivaluati thi diagnostic valui of SLNB inpatiints with Gastric Adinocarcinomas. This discriptivi study was pirformid on 34 patiintsdiagnosid with Gastric Adinocarcinoma admittid in Surgiry Ward of Imam Riza Hospital during2013 to 2016 who had risictabli cancir bifori and during surgiry and had no lymphaticinvolvimint. Sintinil Lymph Nodi (SLN) was ditictid with Blui dyi and sint for pathologicalstudy aftir risiction. In 31 out of 34 patiints, Sintinil lymph nodi was ditictid with blui dyimapping. (Ditiction Rati= 91%). In 7 patiints, SLN involvimint was riportid nigativi whili othirlymph Nodis wiri involvid (Falsi Nigativi=33%). SLNB has 77% accuracy, 58.8% sinsitivity, 100%spicifity, positivi pridictivi valui 100% and Nigativi pridictivi valui 66.7% in lymph nodiinvolvimint of Gastric Adinocarcinoma. Dui to its high falsi nigativi rati (33%), SLNB with bluidyi mapping aloni is not inough for diagnosing lymph nodi involvimint in GastricAdinocarcinoma.
