E-cadherin expressions on bladder and its association with cancer progressivity: a retrospective cohort study

Research output: Contribution to journalArticlepeer-review

Abstract

Background: Bladder cancer is characterized by high recurrence and progressivity. E-cadherin serves as one of the most important molecules involved in the epithelial cells’ cell-to-cell adherence, suggested to inhibit tumor cell progression. This study aims to investigate the association between the E-cadherin expressions with bladder cancer progressiveness in 3 years. Methods: This study was a retrospective cohort study involving bladder cancer patients in Cipto Mangunkusumo Hospital, Jakarta. Diagnosis of bladder cancers was confirmed by histopathological and immunohistochemistry examination between 2011 and 2018, with both grading and staging determined by uropathologists and uro-oncologists. E-cadherin was examined through immunohistochemistry examination at the time of diagnosis. Data on demography, muscle invasion, clinical staging, grade, metastasis, multifocality, and recurrence were obtained from medical records and pathology reports. The association of E-cadherin expression to muscle invasion and non-muscle invasion bladder cancer was evaluated and statistically analyzed. Patients’ survival data were followed up by phone. Results: Forty bladder cancer patients with a mean age of 60.05 ± 10.3 years were included. Most subjects had high E-cadherin expression (85%), muscle invasion (65%), high grade (65%), no metastasis (87.5%), multifocality (65%), and no recurrence (62.5%). Lower expression of E-cadherin was associated with the higher clinical stage (p < 0.02) and metastasis (p < 0.001). Patients with low E-cadherin expression showed worse cumulative survival than the high one (mean 32 months vs. 25 months, p = 0.13). Conclusions: Low level of E-cadherin was associated with the higher risk of muscle invasion, clinical staging, histological grade, and risk of metastasis. Meanwhile, patients with the high level of E-cadherin showed a better three-year survival rate.
