免疫细胞学方法可以检出多种肿瘤弥散至骨髓的肿瘤细胞，在胃肠道癌肿病人的腹腔灌洗液中找出分离的肿瘤细胞，后者当与病人的生存密切相关。作者取84例胃癌和109例结肠直肠癌病人并检定其骨髓和腹腔内的分离细胞（26例未取得骨髓标本，22例因粘连而未能行腹腔灌洗）。8mL骨髓 The immunocytology method can detect tumor cells that spread to many bone marrows and find isolated tumor cells in the peritoneal lavage fluid of patients with gastrointestinal cancer. The latter is closely related to the survival of patients. The authors took 84 cases of gastric cancer and 109 cases of colorectal cancer patients and identified their bone marrow and intra-abdominal isolated cells (26 cases did not obtain bone marrow specimens, 22 cases due to adhesion and can not be peritoneal lavage). 8mL bone marrow
