The objective was to find an association between abnormal glycosylation, represented by Tn and STn antigens on mucin (MUC) proteins, in primary tumor specimens with lymph node metastasis or recurrence of cervical cancer patients. Prospectively collected specimens were obtained from the NRG Oncology/GOG clinical trial GOG 0221 patients with previously untreated stage IB-IVA primary cervical cancer, who underwent surgical resection and removal of associated para-aortic and pelvic lymph nodes. Immunohistochemical staining for mucin 1 and 4 (MUC1 and MUC4) proteins and surface glycoproteins Tn and Sialyl Tn were performed on sections cut from formalin-fixed, paraffin-embedded specimen blocks. Loss vs no loss, of immunohistochemical stain upon neuraminidase treatment was used to verify STn vs Tn positivity, respectively, in patient specimens and in colon tissue from wild-type and T-synthase knockout transgenic mice, which served as STn positive versus STn negative controls, respectively. H-scores of staining intensity and percentage of cells stained was performed by experienced gynecologic pathologists. An experienced gynecologic pathologist also selected photographed regions of interest associated with these cases. The photomicrographs presented in this data set highlight the spectrum of morphologic expression and variability in glycoprotein expression in primary tumors and cancer-positive lymph node specimens. Findings may prove useful in furthering the understanding of cervical cancer glycoproteins, creation of artificial intelligence immunohistochemical scoring systems, and the development of targeted drug therapy.
