ABSTRACT Great advances in screening have lowered the death rate from cervical cancer in the advanced countries. The major advances in cervical cancer screening include the Papanicolaou (Pap) test and liquid-based cytology (LBC). In this study, we aimed to use cell remnants from LBC specimens from uterine cervix and endometrium, aspirates from breast and thyroid tumors, and liquid samples (ascites, pleural effusion, and urine). Cell blocks made from cell remnants of LBC specimens were immunohistochemically or immunocytochemically stained for several biomarkers including certain tumor markers such together with hematoxylin and eosin staining for accurate diagnosis of malignancies in different samples. The findings from the cell blocks stained with these biomarkers combined with those from Pap stain led to easily diagnosis of the presence or absence of malignancies. Our findings suggest the utility of LBC and cell blocks from cell remnants in cytologic diagnosis in certain specimens.
