To determine plasma levels of homocysteine, folate, and vitamin B12 in patients with laryngeal cancer and a control group.
Analysis of homocysteine, folate, and vitamin B12 levels in 25 consecutive untreated patients with laryngeal carcinoma and 80 healthy control participants. The study and control groups were subdivided into smokers, ex-smokers, and nonsmokers, as well as drinkers and nondrinkers.
The AxSYM system was used to measure total homocysteine levels, and the ARCHITECT system (both Abbott-Diagnostics Division) was used to measure folate and vitamin B12 levels.
Homocysteine, folate, and vitamin B12 levels.
The mean (SD) level of total homocysteine in patients with laryngeal carcinoma was 2.84 (1.62) mg/L vs 0.99 (0.24) mg/L in the control group (P <.001). The mean (SD) folate plasma level was 4.3 (2.2) ng/mL vs 7.9 (2.4) ng/mL (P <.001).
Metabolic alterations in homocysteine, folate, and vitamin B12 levels, especially hypofolatemia, could be associated with laryngeal cancer. Lengthier follow-up studies and larger groups of patients will help determine the real role of these metabolic alterations.
测定喉癌患者及对照组血浆中同型半胱氨酸、叶酸和维生素B12的水平。
分析25例未经治疗的连续性喉癌患者及80名健康对照者的同型半胱氨酸、叶酸和维生素B12水平。研究组和对照组又进一步细分为吸烟者、既往吸烟者和非吸烟者,以及饮酒者和不饮酒者。
采用AxSYM系统测定总同型半胱氨酸水平,采用ARCHITECT系统(均为雅培诊断部)测定叶酸和维生素B12水平。
同型半胱氨酸、叶酸和维生素B12水平。
喉癌患者总同型半胱氨酸的平均(标准差)水平为2.84(1.62)mg/L,而对照组为0.99(0.24)mg/L(P<0.001)。血浆叶酸平均(标准差)水平为4.3(2.2)ng/mL,对照组为7.9(2.4)ng/mL(P<0.001)。
同型半胱氨酸、叶酸和维生素B12水平的代谢改变,尤其是低叶酸血症,可能与喉癌有关。更长时间的随访研究和更大规模的患者群体将有助于确定这些代谢改变的真正作用。
