The present case‐control study aimed to investigate the role of interaction of glutathione‐s‐transferase (GST) genotypes with environmental risk factors in determining susceptibility to head and neck squamous cell carcinoma (HNSCC) involving 1,250 cases and equal number of healthy controls. An increase in the risk of HNSCC and its subsites (larynx, pharynx, and oral cavity) was observed among the cases with null genotypes of GSTM1 (odds ratio [OR] = 1.87) or GSTT1 (OR = 1.39) while reduced risk (OR = 0.81) was observed the cases with variant genotype of GSTP1. Tobacco use in the form of smoking or chewing interacted multiplicatively with GSTM1 or GSTT1 to increase the risk several folds (3–10 folds) in HNSCC and its subsites. Alcohol use also increased the risk (2–3 folds) to HNSCC and its subsites in cases with null or variant genotypes of GSTs, though this risk was of lesser magnitude when compared to the tobacco users. A synergistic effect of both, tobacco smoking and alcohol drinking, led to several folds (25‐folds) increased risk to HNSCC among the cases with null genotype of GSTM1 and GSTT1 when compared to nonsmokers and nondrinkers with wild genotype of GSTM1 and GSTT1 in controls. Furthermore, cases with variant genotypes of GSTP1 (Val/Val) showed superior treatment response with improved survival rate and lower risk of death when compared to the patients with wild type genotype (Ile/Ile). The data suggest that though polymorphism in GSTs may be a modest risk factor for determining HNSCC risk, gene‐environment interactions significantly modify the susceptibility to HNSCC by several folds.

谷胱甘肽-S-转移酶基因型与环境危险因素的相互作用,以确定头颈癌的易感性以及治疗反应和生存结果。

本病例对照研究旨在调查谷胱甘肽-s-转移酶(GST)基因型与环境危险因素的相互作用在确定对1,250例头颈鳞状细胞癌(HNSCC)的易感性中的作用,并包括相同数量的健康对照。在基因型为GSTM1(比值比[OR] = 1.87)或GSTT1(OR = 1.39)为无效的基因型病例中,观察到HNSCC及其子部位(喉,咽和口腔)的风险增加。 = 0.81)观察到具有GSTP1基因型变异的病例。吸烟或咀嚼形式的烟草使用与GSTM1或GSTT1相互作用,从而使HNSCC及其亚场所的患病风险增加数倍(3-10倍)。如果GST的基因型无效或变异,则饮酒还会增加HNSCC及其亚部位的风险(2-3倍),尽管与烟草使用者相比,这种风险的程度较小。与非吸烟者和非饮酒者具有野生型GSTM1和GSTT1的基因型相比,吸烟和饮酒的协同作用导致GSTM1和GSTT1基因型无效的病例中HNSCC风险增加了几倍(25倍) 。此外,与野生型基因型(Ile / Ile)的患者相比,具有GSTP1基因型(Val / Val)的患者表现出更好的治疗反应,具有更高的生存率和更低的死亡风险。数据表明,尽管GST中的多态性可能是确定HNSCC风险的适度风险因素,但基因-环境相互作用显着改变了对HNSCC的易感性。与非吸烟者和非饮酒者具有野生型GSTM1和GSTT1的基因型相比,吸烟和饮酒的协同作用导致GSTM1和GSTT1基因型无效的病例中HNSCC风险增加了几倍(25倍) 。此外,与野生型基因型(Ile / Ile)的患者相比,具有GSTP1基因型(Val / Val)的患者表现出更好的治疗反应,具有更高的生存率和更低的死亡风险。数据表明,尽管GST中的多态性可能是确定HNSCC风险的适度风险因素,但基因-环境相互作用显着改变了对HNSCC的易感性。与非吸烟者和非饮酒者具有野生型GSTM1和GSTT1的基因型相比,吸烟和饮酒的协同作用导致GSTM1和GSTT1基因型无效的病例中HNSCC风险增加了几倍(25倍) 。此外,与野生型基因型(Ile / Ile)的患者相比,具有GSTP1基因型(Val / Val)的患者表现出更好的治疗反应,具有更高的生存率和更低的死亡风险。数据表明,尽管GST中的多态性可能是确定HNSCC风险的适度风险因素,但基因-环境相互作用显着改变了对HNSCC的易感性。与对照组中具有GSTM1和GSTT1野生型的非吸烟者和非饮酒者相比,GSTM1和GSTT1基因型无效的病例导致HNSCC风险增加了几倍(25倍)。此外,与野生型基因型(Ile / Ile)的患者相比,具有GSTP1基因型(Val / Val)的患者表现出更好的治疗反应,具有更高的生存率和更低的死亡风险。数据表明,尽管GST中的多态性可能是确定HNSCC风险的适度风险因素,但基因-环境相互作用显着改变了对HNSCC的易感性。与对照组中具有GSTM1和GSTT1野生型的非吸烟者和非饮酒者相比,GSTM1和GSTT1基因型无效的病例导致HNSCC风险增加了几倍(25倍)。此外,与野生型基因型(Ile / Ile)的患者相比,具有GSTP1基因型(Val / Val)的患者表现出更好的治疗反应,具有更高的生存率和更低的死亡风险。数据表明,尽管GST中的多态性可能是确定HNSCC风险的适度风险因素,但基因-环境相互作用显着改变了对HNSCC的易感性。与野生型基因型(Ile / Ile)的患者相比,具有GSTP1基因型(Val / Val)的患者表现出更好的治疗反应,生存率提高,死亡风险降低。数据表明,尽管GST中的多态性可能是确定HNSCC风险的适度风险因素,但基因-环境相互作用显着改变了对HNSCC的易感性。与野生型基因型(Ile / Ile)的患者相比,具有GSTP1基因型(Val / Val)的患者表现出更好的治疗反应,生存率提高,死亡风险降低。数据表明,尽管GST中的多态性可能是确定HNSCC风险的适度风险因素,但基因-环境相互作用显着改变了对HNSCC的易感性。
