Vaginal intraepithelial neoplasia: risk factors for persistence, recurrence, and invasion and its management.

OBJECTIVE: Our purpose was to profile patients with vaginal intraepithelial neoplasia, evaluate the response to treatment and define risk factors for persistence and progression. STUDY DESIGN: We reviewed records and histopathology slides of 94 patients with vaginal intraepithelial neoplasia diagnosed from 1977 to 1986. For 74 patients with follow-up, we evaluated risk factors by univariate and multivariate analyses. RESULTS: Sixty-four of 94 patients (68%) had prior or concurrent anogenital squamous neoplasia, including 21 with invasive and 43 with intraepithelial. Twenty-three had prior radiotherapy, 10 had anogenital neoplastic syndrome, and 11 were immunosuppressed. In 52 of 74 treated patients (70%), vaginal intraepithelial neoplasia went into remission after a single treatment. In 18 patients (70%) vaginal intraepithelial neoplasia went into remission after a single treatment. In 18 patients (24%) recurrent vaginal intraepithelial neoplasia went into remission after chemosurgery, upper vaginectomy, or other treatments; in 4 (5%) it progressed to invasion. Significant multivariate risk factors for persistence or progression were multifocal lesions and anogenital neoplastic syndrome but not vaginal intraepithelial neoplasia grade, associated cervical neoplasia, or immunosuppression. CONCLUSIONS: Although most vaginal intraepithelial neoplasia goes into remission after treatment, 5% of cases may progress from occult foci to invasion in spite of close follow-up.

Multiple recurrences of cervical intraepithelial neoplasia in women with the human immunodeficiency virus.

OBJECTIVE: To evaluate the long-term outcomes after treatment of cervical intraepithelial neoplasia (CIN) in women infected with the human immunodeficiency virus (HIV). METHODS: Human immunodeficiency virus-infected and HIV-negative women treated for CIN by ablation or excision were followed-up prospectively by cytology and colposcopy for periods of up to 73 months. RESULTS: Among 127 HIV-infected CIN patients, 62% developed recurrent CIN by 36 months after treatment, compared with 18% of the 193 HIV-negative CIN patients. Recurrence rates reached 87% in 41 HIV-infected women with CD4 counts less than 200 cells/mm3. Progression to higher-grade neoplasia, including one invasive cancer, occurred by 36 months in 25% of HIV-infected and 2% of HIV-negative women. After adjusting for age, CIN severity, and treatment type, predictors of recurrence included HIV infection (rate ratio 4.4), and, in HIV-positive women, low CD4 count (rate ratio 2.2). In patients treated by excision, predictors of recurrence included HIV infection (rate ratio 2.0) and residual CIN after treatment (rate ratio 2.7). After a second treatment,a second CIN recurrence developed in 14 of 33 HIV-infected and in one of 17 HIV-negative women. After a third treatment, three of six HIV-infected women developed a third recurrence. With long-term follow-up, 45% of treated HIV-infected CIN patients had chronic condylomatous changes in the cervix compared with 5% of HIV-negative women. CONCLUSION: In HIV-infected women, CIN may recur despite multiple treatments, and chronic condylomatous changes are common. Innovative therapies for controlling CIN in HIV-infected women are needed.

Variations in human placental 11 beta-dehydrogenase and 11-oxoreductase activities of 11 beta-hydroxysteroid dehydrogenase enzyme during pregnancy.

Human placental 11 beta-hydroxysteroid dehydrogenase enzyme has an important role in controlling glucocorticoids reaching the fetus. Excess glucocorticoids impair fetal growth. Recent investigations show that the placenta is rich in NAD- and NADP-dependent 11 beta-hydroxysteroid dehydrogenase activity. Elucidation of the activities of both these isoforms is necessary to understand placental glucocorticoid metabolism. Hence we determined both NAD- and NADP-dependent 11 beta-hydroxysteroid dehydrogenase activities throughout pregnancy. 11 beta-dehydrogenase (oxidative) and 11-oxoreductase (reductive) activities of 11 beta-hydroxysteroid dehydrogenase were determined in 16 first-trimester (9-12 weeks) and 14 second-trimester (13-22 weeks) and 17 term (38-42 weeks) placentae. Both NAD- and NADP-dependent activities increased with pregnancy. The second-trimester NAD-dependent activity was higher than the first-trimester activity (p = 0.02). At term this activity was higher than during the second (p = 0.05) and first (p = 0.0002) trimesters. A similar increase was obtained with NADP isoform except that the difference between first and second trimesters was not significantly different at p = 0.05. The NADH-dependent 11-oxoreductase activity was also detected throughout the pregnancy. However, the activity at term was significantly higher than during the second (p = 0.005) and first (p = 0.001) trimesters. This increase may result in a concomitant increase of cortisol reaching fetus, thus helping fetal lung maturation.

Characteristics of cervical intraepithelial neoplasia in women infected with the human immunodeficiency virus.

OBJECTIVE: Our purpose was to compare characteristics of cervical intraepithelial neoplasia in relation to human immunodeficiency virus infection among women referred to a public hospital colposcopy clinic with Papanicolaou smears showing cervical intraepithelial neoplasia. STUDY DESIGN: An evaluation of cervical intraepithelial neoplasia severity, lesion size, and vulvovaginal lesions with respect to human immunodeficiency virus status was performed. RESULTS: (1) Human immunodeficiency virus prevalence in 482 women with cytologic characteristics of cervical intraepithelial neoplasia was 13%. (2) In human immunodeficiency virus-infected patients, Papanicolaou smears were less adequate for evaluation and correlated less well with histologic findings than in uninfected patients (p < 0.05). (3) Human immunodeficiency virus-infected patients (n = 47) had more advanced cervical intraepithelial neoplasia, larger cervical lesions, and more associated vulvovaginal lesions than human immunodeficiency virus-negative patients (n = 161). In human immunodeficiency virus-positive women, the severity of cervical intraepithelial neoplasia was not associated with age, whereas in human immunodeficiency virus-negative women, increasing severity was significantly associated with increasing age. CONCLUSION: High rates of human immunodeficiency virus infection in inner-city colposcopy services and high-grade, extensive cervical lesions in infected women warrant special attention.

Adenomyosis.

The clinical diagnosis of adenomyosis is elusive but should be suspected in women who complain of abnormal uterine bleeding or dysmenorrhea and have a regular but enlarged uterus. The use of newer diagnostic imaging modalities and recent research on myometrial biopsies should enable the clinician to arrive at a definite preoperative diagnosis and offer the patient treatment tailored to her needs.

Pap smear histories in a medical clinic: accuracy of patients' self-reports.

Women using the medical clinic of a public hospital were interviewed about their Pap smear histories to assess the accuracy of self-reported smears and to identify groups in need of further screening. Interview data from 263 women were compared with cytology files and hospital records. In spite of considerable agreement between patient report and record, patients reported significantly more recent smears than were documented. Accuracy of recall was not dependent on age or birthplace, but on the length of time since the last smear. About half the women had been screened within the past two years, whereas one tenth had never been screened. Women aged 65 years or older had fewer recent smears than younger women, while foreign born women were more likely never to have had a Pap smear than were United States born women. We conclude that self-reported information is useful in assessing Pap smear histories, but the screening rates that result should be treated as high estimates. Significant opportunities for screening exist in ambulatory care sites in low-income communities.

Predictive value of computerized tomography in the presurgical evaluation of primary carcinoma of the cervix.

To determine the predictive value of abdominal-pelvic CT scan in assessing pelvic and paraaortic node metastases in untreated cervical carcinoma, the preoperative CT scans of 61 patients were compared with the gross and microscopic surgical findings. Although 75% of enlarged pelvic nodes on CT contained metastases, and 97% of patients with negative pelvic nodes had negative CT scans (specificity = 97%), histologically positive pelvic nodes were often missed on CT scan (sensitivity = 25%). For paraaortic nodes the CT scan had a specificity of 100% and a sensitivity of 67%. No paraaortic nodes were enlarged in stages I-IIA (0/51). CT scans are recommended for routine evaluation of paraaortic nodes in stages II-IV, but are not warranted in pretreatment evaluation of the pelvic nodes in stage I.
