“…Следует отметить, что большое количество потенциальных факторов риска развития злокачественных новообразований, сложность взаимодействий средовых факторов и генетической предрасположенности, возможность ассоциированного действия комбинаций факторов риска диктуют необходимость крайне аккуратного отношения к положению о потенциальных рисках, связанных с применением витаминов группы В. Убедительных свидетельств стимуляции процессов онкогенеза при их применении на сегодняшний день не получено. Напротив, имеются многочисленные свидетельства того, что применение указанных витаминов может уменьшать риск развития рака молочной железы, желудка [52]. Более того, имеются данные о целесообразности и безопасности применения витаминов группы В, в том числе витамина В 12 , у пациентов, нуждающихся в коррекции их дефицита после резекции желудка, проведенной химиотерапии, некоторых других состояниях, связанных с онкологическими заболеваниями.…”

Serum Homocysteine and Vitamin B12 as Biomarkers for Haematological Toxicity in Lung Adenocarcinoma Treated With Pemetrexed

et al. 2019

Background Serum homocysteine (Hcy) and vitamin B12 (VitB12) were investigated as serological markers for the prediction of pemetrexed induced haematological toxicity in patients with adenocarcinoma of the lung. Material and Methods A total of 35 lung adenocarcinoma patients who received pemetrexed chemotherapy as first-line treatment were included in the present study. The patients received pemetrexed 500 mg/m2 once every three weeks until disease progression. Serum Hcy and VitB12 levels were analysed prior to chemotherapy. Haematological toxicities (leucopenia, neutropenia and thrombocytopenia) were graded for each cycle of chemotherapy. Serum Hcy and VitB12 concentrations were compared between grades 0-1 and 2-4 haematological toxicity groups. Results A total of 151 chemotherapy cycles were administered to 35 lung adenocarcinoma patients. However, the serum Hcy and VitB12 concentration were only examined and recorded in 61 out of the 151 chemotherapy cycles. For the 61 cycles, grade 2-4 leucopenia, neutropenia and thrombocytopenia were observed in 21, 20 and 10 cases, respectively. Serum Hcy levels were 14.91±4.67 μg/ml, 15.50±4.35 μg/ml and 16.04±4.90 μg/ml for grade 2-4 leucopenia, neutropenia and thrombocytopenia, respectively, which were significantly higher than those of grade 0-1 groups (p<0.05). However, serum VitB12 were not statistically different between grade 0-1 and 2-4 haematological toxicity groups (p>0.05). The area under the ROC curve (AUC) were 0.73 (0.58-0.88), 0.80 (0.66-0.94), 0.75 (0.57-0.93) for serum Hcy and 0.65 (0.50-0.79), 0.64 (0.49-0.78), 0.68 (0.49-0.87) for serum VitB12 as predictive biomarkers of grade 2-4 leucopenia, neutropenia and thrombocytopenia, respectively. Conclusion Pre-chemotherapy serum Hcy appeared to correlate with haematological toxicity and may be a useful biomarker for predicting severity of pemetrexed induced haematological toxicity.
