OBJECTIVE: The current study evaluated the expression of WW domain-containing oxidoreductase (WWOX), its association with clinicopathological features and with p53, Ki-67 (cell proliferation) and CD31 (angiogenesis) expression in patients with invasive cervical squamous cell carcinoma (ICSCC). To the best of our knowledge, no other study has evaluated this association. METHODS: Women with IB stage-ICSCC (n = 20) and women with uterine leiomyoma (n = 20) were prospectively evaluated. Patients with ICSCC were submitted to type B-C1 radical hysterectomy and pelvic lymphadenectomy. Patients in the control group underwent vaginal hysterectomy. Tissue samples were stained with hematoxylin and eosin for histological evaluation and protein expression was detected by immunohistochemistry studies. RESULTS: The WWOX expression was significantly lower in the tumor compared with the expression in the benign cervix (p = 0.019). The WWOX expression was inversely associated with the CD31 expression in the tumor samples (p = 0.018). There was no association between the WWOX expression with the p53 expression (p = 0.464) or the Ki-67 expression (p = 0.360) in the samples of invasive carcinoma of the cervix. There was no association between the WWOX expression and tumor size (p = 0.156), grade of differentiation (p = 0.914), presence of lymphatic vascular invasion (p = 0.155), parametrium involvement (p = 0.421) or pelvic lymph node metastasis (p = 0.310) in ICSCC tissue samples. CONCLUSION: The results suggested that WWOX may be involved in ICSCC carcinogenesis, and this marker was associated with tumor angiogenesis. Thieme Revinter Publicações Ltda Rio de Janeiro, Brazil.
