PURPOSE: to evaluate the association between p53 and Ki-67 expression in the tumor and clinicopathological features in patients with carcinoma of the cervix. METHODS: samples were taken from the tumor of 36 patients with stage IB (FIGO) cervical carcinoma submitted to radical hysterectomy. Tissue samples were taken from the tumor, fixed in formalin and embedded in paraffin. The specimens were analyzed by histopathology (hematoxylin and eosin) and immunohistochemically evaluated using monoclonal antibodies for p53 and Ki-67. Data were analyzed statistically by the chi2 test to evaluate eventual differences between the groups. RESULTS: the age of the patients ranged from 27 to 73 years (48.7±10.4 years). Clinical stage (FIGO) was IB1 in 27 cases (75%) and IB2 in 9 cases (25%). A positive tumoral expression of the p53 protein was found in half of the cases. In relation to the Ki-67 expression, a high cell proliferation index was shown in 73.3% of the cases. There was no association between tumoral p53 and Ki-67 expression with age (p=0.091 and 0.900), clinical stage (p=0.054 and 0.667), histological classification (p=0.674 and 0.674), grade of differentiation (p=0.070 and 0.282), presence of lymphatic vascular space invasion (p=0.248 and 0.667), parametrial involvement (p=0.729 and 0.763) and pelvic lymph node metastasis (p=0.729 and 0.636, respectively). CONCLUSIONS: tumoral expression of p53 and Ki-67 was not associated with the clinicopathological features in patients with stage IB carcinoma of the cervix.

OBJECTIVE: to evaluate the incidence of non-gynecological surgical procedures used in the treatment of ovarian cancer, as well to describe their complications. METHODS: eighty-two patients with ages from 22 to 89 (mean = 54.1 ± 15.1 years), submitted to laparotomy for surgical treatment of ovarian cancer from February 1999 to October 2003 were retrospectively evaluated. This study included only patients with epithelial ovary carcinoma. The patients were divided into 2 groups, patients submitted exclusively to gynecological procedures and patients submitted to non-gynecological procedures. Statistical analysis was made with the Student's t-test or the chi-square test. RESULTS: 5 patients (6.1%) were in stage (FIGO) I, 18 (21.9%) in stage II, 40 (48.8%) in stage III, and 19 (23.2%) in stage IV. Non-gynecological procedures were done in 35 cases (42.7%), including: 17 colostomies, 16 enterectomies, 8 peritonectomies, 7 colectomies, 5 partial diaphragm resections, 4 partial cystectomies, 4 splenectomies, 2 ileostomies, and 1 hepatectomy. All patients submitted to non-gynecological procedures were included in stages III and IV. This group of patients underwent longer-lasting surgeries (5.3 ± 1.4 versus 3.1 + 0,0 h; p < 0.001). There was no significant difference between these two groups regarding hemotransfusion requirement (42,2 versus 40%; p = 0.512) and hospitalization time (11.5 ± 7.2 versus 10 ± 9.9 days; p = 0.454). Patients submitted to non-gynecological surgeries developed higher rates of postoperative complications (37 versus 17.1%; p = 0.042), and two of them (2.4%) died. CONCLUSION: non-gynecological surgical procedures are frequently used in the treatment of patients with ovarian cancer. These procedures are associated with a longer-lasting surgery and higher rates of postoperative complications.

PURPOSE: to evaluate the results of the use of bovine pericardium in the pubovaginal sling procedure for treatment of stress urinary incontinence. METHODS: a prospective analysis of five patients who underwent pubovaginal sling with the use of bovine pericardium strip for stress urinary incontinence in the "Hospital das Clínicas of UFMG" from October/2001 to December/2001. The mean age was 48.2±11.5 years (33 to 69 years). RESULTS: the mean surgical time was 45±35.3 min and the mean hospital stay was 36±12.4 h (24 to 48 h). Complications in the periperative or immediate postoperative period did not occur. All patients initially presented satisfactory results with normal voiding and without stress incontinence. Postoperative complications occurred in the 5 patients (100%), with dehiscence of the vaginal wound and total expulsion of the strip in 2 patients (40%) and partial expulsion in 3 patients (60%). All patients presented stress urinary incontinence and were submitted to a new sling procedure using the rectus fascia. The patients then progressed without complications and with improvement of urinary continence in 4 patients (80%). CONCLUSIONS: pubovaginal sling with the use of bovine pericardium was associated with high rates of complications. Therefore, its use is not recommended in the treatment of stress urinary incontinence.
