目的探討術(shù)前胃動(dòng)脈化療栓塞對(duì)胃癌淋巴結(jié)轉(zhuǎn)移灶癌細(xì)胞凋亡的影響。
方法對(duì)40例胃癌伴淋巴結(jié)轉(zhuǎn)移患者行胃癌根治性切除術(shù),根據(jù)術(shù)前是否行胃動(dòng)脈化療栓塞分為治療組和對(duì)照組,各20例,采用免疫組化ABC法檢測(cè)淋巴轉(zhuǎn)移灶p53、bcl2及CD95基因的表達(dá),原位末端脫氧核苷轉(zhuǎn)移酶標(biāo)記法(TUNEL)檢測(cè)細(xì)胞凋亡情況。
結(jié)果治療組淋巴轉(zhuǎn)移灶p53和CD95表達(dá)較對(duì)照組明顯增強(qiáng)(P<0.05),并與細(xì)胞凋亡呈正相關(guān),bcl-2表達(dá)則減低與細(xì)胞凋亡呈負(fù)相關(guān)。
結(jié)論胃癌術(shù)前行胃動(dòng)脈化療栓塞,可能通過(guò)p53、bcl-2及CD95介導(dǎo)使轉(zhuǎn)移淋巴結(jié)癌細(xì)胞凋亡增加,有助于提高根治性手術(shù)的治療效果。
