恶性肿瘤细胞一般都有染色体异常,胃癌也不例外;然而胃癌细胞均须经过手术或活检才能获得,故在诊断中其应用受到一定限制。为了开展对肿瘤患者外周血T 淋巴细胞染色体的研究,探讨其变化对临床诊断和预后的意义,首先,我们对53例胃癌患者的 T 淋巴细胞染色体进行了调查。 Malignant tumor cells generally have chromosomal abnormalities, and gastric cancer is no exception. However, gastric cancer cells must be obtained through surgery or biopsy, so its application in the diagnosis is limited. In order to carry out studies on the chromosomes of peripheral blood T lymphocytes from patients with cancer, and to explore the significance of the changes in clinical diagnosis and prognosis. First, we investigated the chromosomes of T lymphocytes in 53 patients with gastric cancer.
