慢性淋巴细胞白血病(简称慢淋),是西方国家较常见的一种白血病。约占白血病的20～30％。亚洲地区则少见。在日本约占白血病的2.6％。国内大组白血病分析中约占1.1％。因此,报告者甚少。随着近年来免疫生物学和对淋巴细胞研究的进展,对本病的认识不断深入。由于本病的临床表现和病程变异较大,多数起病慢,约1/4的病人开始可完全症状没有,常易漏诊或误诊。 Chronic lymphocytic leukemia (referred to as CLL), is a more common Western Western leukemia. About 20 to 30% of leukemia. Asia is rare. About 2.6% of leukemia in Japan. Domestic large group of leukemia analysis accounted for about 1.1%. As a result, there are very few reporters. With the progress of immunobiology and lymphocyte research in recent years, the understanding of this disease continues to deepen. Due to the clinical manifestations of the disease and course of variation is large, most of the slow onset, about 1/4 of the patients can start without symptoms, often misdiagnosis or misdiagnosis.
