Исследования, направленные на оценку их роли в процессах развития рака различны, а оценка исходного уровня витаминов актуальна при планировании противоопухолевой терапии.</p><sec><title>Цель исследования</title><p>Цель исследования. Определить состояние исходного уровня витаминов группы В и гомоцистеина перед проведением химиотерапии у пациентов разного онкологического профиля.</p><p>Материалы и методы исследования. Определён уровень витаминов В1, В6, В9, активной формы В12* и гомоцистеина всвежезамороженной плазме методом иммуноферментного анализа (ИФА) с использованием тест-систем у 66 пациентов с верифицированными злокачественными новообразованиями ЗНО) до химиотерапии. В исследование включено 66 пациентов: женщины n=40 и мужчин n=26, с ЗНО: раком желудка n=12, колоректальным раком n=21, раком легких n=11, раком органов малого таза n=22.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. По результатам исследования повышение уровня холотранскобаламина (Холо-ТК) и снижение гомоцистеина в сравнении с референтными значениями наблюдалось в 100% случаев. Значимое различие обнаружено только для В1: достоверные различия между пациентами с колоректальным раком и с раком малого таза (у последних среднее значение уровней В1 было выше в 2.4 раза при p = 0.0425). По результатам корреляционного анализы определена слабая связь между В12 и В9. При сравнении уровня витамина В12 и гомоцистеина у пациентов после оперативного лечения и без него не было выявлено достоверных различий.</p></sec><sec><title>Заключение</title><p>Заключение. Повышение уровня Холо-ТК и снижение уровня гомоцистеина методом ИФА характерно для всех разновидностей солидного рака, не зависит от пола, возраста, стадии и предшествующего оперативного вмешательства. Относительное снижение витамина В1 характерно для колоректального рака.</p></sec></abstract><trans-abstract xml:lang="en"><p>Recently, the role of vitamin imbalance in carcinogenesis has been actively discussed.

According to the results of correlation analysis, a weak correlation between B12 and B9 was determined.

Increased Holo-TC levels and decreased homocysteine levels by ELISA are characteristic of all varieties of solid cancer, independent of sex, age, stage and previous surgical intervention.
