PURPOSE: to evaluate the diagnostic procedures used in women with Pap smear result of atypical glandular cells. PATIENTS AND METHODS: a prospective study with 159 women with atypical glandular cells was carried out between January and December 2000. All women were submitted to a new colpocytology and to colposcopy. Directed biopsy was performed in 50 cases, endocervical curettage in 21 and conization in 75. The performance of the diagnostic procedures was described by estimating the sensitivity, specificity, predictive values and likelihood ratio, considering histological results as gold standard. RESULTS: the histological evaluation showed 51 intraepithelial squamous lesions, 29 low grade and 22 high grade. Five women presented in situ adenocarcinoma and six patients presented invasive neoplasias. Colpocytology alone showed sensitivity and specificity of 88.5 and 39%, respectively, and colposcopy alone, 74 and 42%. The association of colpocytology with colposcopy increased the sensitivity to 98.4%, with a significantly lower specificity of 10%. Endocervical curettage showed low sensitivity (25%). CONCLUSION: the presence of atypical glandular cells on colpocytology was associated with preinvasive and invasive cervical lesions in 62.2% of the cases with histological evaluation. Repeating colpocytology and performing colposcopy allowed to select the women who needed histological evaluation. Conization was an adequate procedure when examination continued to show morphologic alterations.

The purpose of the present study was to evaluate some epidemiological, clinical and pathological characteristics of the different grades of vulvar intraepithelial neoplasia (VIN), and its relation with the presence of human papillomavirus (HPV). The charts of 46 women with VIN, examined from 1986 through 1997, were reviewed. For statistical analysis the chi² with yates correction when appropriate, and Fisher's exact tests were used. Regarding the grade of VIN, six women presented VIN 1, six others had VIN 2 and the remaining 34 presented VIN 3. All women presented similar characteristics such as age, menstrual status and age at first sexual intercourse. Women with more than one lifetime sexual partner had a tendency to show more VIN 3 (p = 0.090). Cigarette smoking was significantly associated with the severity of the vulvar lesion (p = 0.031). HPV was significantly more frequent in women younger than 35 years of age (p = 0.005) and in women with multiple lesions (p = 0.089). Although the number of lesions were not related to the severity of VIN (p = 0.703), lesions with extensions greater than 2 cm were significantly associated with VIN 3 (p = 0.009). The treatment of choice for VIN 3 was surgery, including local resection and simple vulvectomy. Eight women relapsed, and only one had VIN 2. We concluded that among women with VIN, cigarette smoking and more than one lifetime sexual partner were associated with high-grade lesions. HPV was more frequent among patients younger than 35 years of age presenting multiple lesions. Women with VIN 3 presented lesions bigger than 2 cm and a high relapse rate, despite the type of treatment applied.

The purpose of the present study was to compare postoperative complications and recurrence rates in 132 women with invasive vulvar carcinoma treated by radical vulvectomy and bilateral groin lymphadenectomy performed with one or three incisions. It was a nonrandomized retrospective clinical study, including 65 women operated using a single incision and 67 with three incisions, between 1986 and 1996. Fischer's, chi-square, Student's t tests followed by logistic regression were used for statistical analysis as well as survival curves by the Kaplan-Meyer method, compared using Wilcoxon test, followed by Cox regression, with the statistical significance limit of 5%. The groups were similar regarding age, smoking, presence of other diseases, histologic type and grade. Pathologic stage III was significantly more frequent in the single incision group, while free lymph nodes were more frequent in the three-incision group. The patients treated with triple incision showed statistically less frequent immediate complications (76% vs 92%, p<0.05), less dehiscence (72% vs 92%, p<0.01), and shorter mean hospital stay (19.4 days vs 38.7 days, p<0.001) and secondary procedures were less necessary (76% vs 94%, p<0.01). Seven postoperative deaths were observed: five with single incision and two with triple incision. Recurrence rate was statistically lower in patients treated with triple incision (19% vs 35%, p<0.01) and with negative lymph nodes (6% vs 15%, p<0.01). After Cox regression, only positive lymph nodes had negative influence on disease-free survival. We concluded that vulvectomy using three incisions shows less complications than single incision, without compromising therapeutic efficacy, independently of the stage of the disease.
