Одновременно изучали иммунофенотип лимфоцитов периферической крови (включая κ/λ-соотношение легких цепей Ig), выраженность абсолютного лимфоцитоза и клинические проявления болезни. У 11 из 15 больных отмечен клональный характер изменений концентраций СЛЦ. При этом у 7 установлен κ-тип клона (κ/λ &gt; 1,65), у 4 – λ-тип клона (κ/λ &lt; 0,26). Клональность по СЛЦ совпадала с изотипом легких цепей Ig клональных В-лимфоцитов, установленным при иммунофенотипическом исследовании. У остальных 4 больных не выявлено клонального характера концентраций СЛЦ, хотя была обнаружена рестрикция по λ-типу легкой цепи на мембране клональных В-лимфоцитов и наличие абсолютного лимфоцитоза в анализах крови. У 10 больных концентрацию СЛЦ изучали до и после проведения 6 курсов RFC-терапии. В этой группе у 6 больных был обнаружен опухолевый клон СЛЦ. После лечения у 4 пациентов получено снижение концентрации опухолевых легких цепей в среднем на 63,1%, нормализация κ/λ-соотношения на В-лимфоцитах, что совпадало с отсутствием абсолютного лимфоцитоза. У 2 больных не было отмечено снижения концентрации опухолевых СЛЦ, хотя нормализовалось κ/λ-сооотношение на мембране В-лимфоцитов, отсутствовал абсолютный лимфоцитоз, что сопровождалось клиническим улучшением. У 4 больных концентрация СЛЦ сыворотки крови до и после лечения колебалась в пределах нормальных значений. Таким образом, у 73,7% больных в ходе исследования был отмечен клональный характер изменений концентраций СЛЦ. Данный критерий можно рассматривать как интегральный показатель массы опухоли и фактор эффективности терапии.</p></abstract><trans-abstract xml:lang="en"><p>Presence of Serum-Free Immunoglobulin Light Chains (sFLC) was analyzed for 15 patients with newly diagnosed Chronic Lymphocytic Leukemia (CLL). All patients were also characterized by peripheral blood lymphocytes’ immunotype (including κ/λ), presence of absolute lymphocytosis and clinical data. Of the 15 patients 11 had elevated concentrations of monoclonal sFLC: 7 patients had elevated κ sFLC (κ/λ ratio &gt; 1,65); 4 patients had elevated λ sFLC (κ/λ ratio &lt; 0,26). The type of elevated clone for sFLC was the same as the isotype of clonal lymphocytosis. The remaining 4 of 15 patients did not have elevated concentrations of sFLC whereas clonal lymphocytosis (λ type for all 4 patients) and absolute lymphocytosis were observed. 10 of 15 patients received 6 courses of RFC-therapy. For those patients sFLC concentration was measured before and after the therapy. In 6 of 10 patients tumor clone of sFLC was detected. After RFCtherapy, 4 of those patients demonstrated a reduction in concentrations of elevated sFLC on average for 63,1% and a normal κ/λ ratio that corresponded with the absence of clonal and absolute lymphosytosis. The remaining 2 patients did not have a decrease in sFLC concentrations and had abnormal κ/λ ratio, however, tumor clone lymphocytes and absolute lymphocytosis were not detected, that was presented with better overall clinical outcome. In 4 out of 10 patients that demonstrated no initial elevation in clonal sFLC, measured sFLC concentrations varied within the normal range. Conclusions: 73,7% of CLL patients in our study showed elevated concentrations of clonal sFLC. Serum-Free Light Chains concentration could serve as an integral criterion for evaluation of tumor mass and therapy effectiveness.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>свободные легкие цепи</kwd><kwd>хроническим лимфолейкоз</kwd><kwd>RFC-терапия</kwd><kwd>эффективность лечения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Serum-Free Light Chains</kwd><kwd>Chronic Lymphocytic Leukemia</kwd><kwd>RFC-therapy</kwd><kwd>therapy effectiveness</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Martin W., Abraham R., Shanafelt T., Clark R.J., Bone N., Geyer S.M., et al.
