Rectal gland samples were histologically processed with hematoxylin/eosin and special Masson's Trichrome stain. Three main regions were identified: the capsule, secretory parenchyma and central duct.

The duct to which the organ's secretory tubules open, at the center of the rectal gland, presents a lumen lined with stratified epithelium, containing acidophilic intraepithelial and mucous cells.

This study evaluated the clinical efficacy of OncoTherad (MRB-CFI-1) nanoimmunotherapy in patients with BCG-unresponsive NMIBC and investigated correlations between therapeutic outcomes and histopathological and molecular findings. In this retrospective cross-sectional study, 20 patients with BCG-unresponsive NMIBC were treated with OncoTherad (MRB-CFI-1) across two clinical centers. Bladder tissue samples were collected before and after treatment, and immunohistochemical analyses were performed to assess the expression of SERBP1, HABP4, CD44, and Ki-67. Primary endpoints included pathological complete response (pCR), recurrence-free survival (RFS), and duration of response (DoR), which were analyzed in relation to immunohistochemical biomarker findings. Our results demonstrated that high Ki-67 proliferative index and elevated immunoreactivity for CD44 and SERBP1 were associated with shorter RFS. Treatment with OncoTherad (MRB-CFI-1) significantly reduced (p < 0.05) the immunoreactivity of SERBP1 and CD44, which was accompanied by a marked decrease in Ki-67 proliferative index, indicating effective suppression of tumor activity.
