The Cardiff Cervical Cytology Study: prevalence of cytological grades and initial histological findings.

Among 45 266 women in the Cardiff Cervical Cytology Survey the peak prevalence of suspicious or positive smears was 11.2/1000 at age 45-50 years and of dyskaryosis 10.2/1000 at age 25-29. A suspicious or positive cytological picture at prevalence testing was associated with occult or clinical invasion in 24% of cases, and only 4% of patients with suspicious or positive smears were normal histologically. When dyskaryosis was detected in the prevalence test 20% had carcinoma in situ or microinvasion and 3% had occult or clinically invasive carcinoma. One hundred and twenty-nine (51%) women with dyskaryotic smears did not have a biopsy initially (that is, within two years of the prevalence test), but they were followed up at regular intervals. Subsequently 15 of the 129 gave smears consistently dyskaryotic or worse cytologically and were subjected to biopsy. Of these, two showed dysplasia, 12 carcinoma in situ, and one clinically invasive carcinoma. These findings emphasise the need for repeat cytological or histological examination in any woman with evidence of dyskaryosis in a cervical smear.     

Colposcopy in a family planning clinic: a future model?

The first year''s experience of a satellite colposcopy clinic in the Glasgow Family Planning Centre was analysed. Establishment of the clinic was supervised by an experienced member of the colposcopy team at the department of gynaecology, Western Infirmary, Glasgow, who trained one of the family planning centre''s staff. Close links were thus maintained with the hospital clinic to which patients were referred for treatment. The policy at the new colposcopy clinic was to study prospectively all women in the hospital catchment area whose cervical smears were reported as abnormal. In 58 of 162 such patients there was at least moderate dyskaryosis and the cytologist''s recommendation had been referral for colposcopy. In 104 cases the changes were either atypia alone or mild dyskaryosis and a repeat smear was recommended within three to 12 months; 18 of these patients had grade II or III cervical intraepithelial neoplasia on biopsy, and relying on repeat smears would have resulted in an 11.7% false negative rate. If an atypical cytological picture is to be an indication for colposcopy clinics attached to family planning centres may have an important role, given satisfactory training and close links with central specialist colposcopy clinics.     

Evaluation of p16INK4a in cervical lesion of premenopausal and postmenopausal women

Pap smears of postmenopausal women are often misdiagnosed because of the difficulty in distinguishing atrophic epithelial cells groups only by morphological criteria. In this study we investigated the diagnostic application of immunocytochemical staining of p16INK4a on conventional Pap smear. A total of 137 cervical specimens were enrolled in this study, of which 77 and 60 cervical smears were taken from premenopausal and postmenopausal women, respectively. Two cervical smears were taken simultaneously in 68 women, one for conventional cytology and the other for immunostaining. Additional 69 cervical smears were taken from the archive, decolorized and then used for immunostaining. In premenopausal women 1 out of 14 (7.1%) with negative cytology, 7 out of 24 (29.2%) with low grade squamous intra-epithelial lesion (LSIL), all 35 (100%) with high grade squamous intraepithelial lesion (HSIL) and all 4 (100%) with squamous cell carcinoma (confirmed by histopathology) had positive staining to p16INK4a. In postmenopausal women p16INK4a positivity was observed in 4 out of 7 (57.1%) cases of LSIL, 12 out of 14 (85.7%) cases of HSIL and all 4 out of 5 (80%) different cases of carcinoma (1 cervical adenosquamous carcinoma and 3 cervical squamous cell carcinoma in situ confirmed by histopathology), but none of 34 smears with normal cytology. Twenty smears with normal cytology chosen for the negative control in this study were from the group of postmenopausal women and were as expected negative for p16INK4a immunostaining. In the group of postmenopausal women, 16 out of 60 (26.7%) cases the cytological diagnosis was established on the basis of pl6lNK4a immunostaining as being HSIL. From our preliminary study on a limited number of samples, we can however conclude that pl6INK4a immunostaining is a very useful tool for cytological diagnosis enabling to distinguish HSIL from normal, reactive or inflammatory changes.     

The Irrigation Smear—A New Cytodiagnostic Technique for the Detection of Cancer of the Uterine Cervix

Using the Davis cytopipette, cytologic smears were prepared from 2014 patients; 1367 of these specimens were obtained by the patients themselves. The series included 57 cases of carcinoma or atypia of the cervix, and 50 (88%) of these cases were found to have abnormal cells in the irrigation smear.Cytopipette samples were obtained by a nurse from 647 Eskimos, but cell preservation in this group was not satisfactory because of a delay of several weeks in preparing the smears. Accurate results depend also on specific training of the personnel reading the smears because fewer cells may be present in these smears than in cervical scrape smears.The irrigation smear is recommended as a reasonably accurate method of screening women for cancer of the cervix if they are not being examined regularly by the cervical scrape method. Hospital admissions of females may be a fruitful source of such cases.     

Adherence to recommendations for early repeat cervical smear tests.

OBJECTIVE--To assess adherence to recommendations for an early repeat cervical smear test in women with reports of cytological abnormalities, and to evaluate the impact of reminder letters to medical practitioners when such smear tests are overdue. DESIGN--Observational study. SETTING--Cytology (gynaecological) service for Victoria, Australia. SUBJECTS--Two groups of women who had abnormal cervical smears during 1985. Women in group A had some evidence of an important dysplasia and were advised to have a repeat smear in three months'' time whereas women in group B had a less serious abnormality and were advised to have a repeat smear test in six months'' time. In all, 971 of the 1036 women in group A and 1401 of the 1464 women in group B were eligible to have a repeat smear analysed by the service. INTERVENTION--If a repeat smear had not been received within three months of the recommended date a reminder letter generated by the service''s computer was sent to the medical practitioner who had taken the smear. END POINT--Thirty six months after the report on the abnormal smear was issued. MEASUREMENTS AND MAIN RESULTS--In all, 870 (90%) of the women in group A and 1154 (82%) of the women in group B had a repeat smear test. The mean time to a repeat test was 3.0 months (95% confidence interval 0.5 to 16.4) in group A and 6.0 months (1.2 to 30.3) in group B. The reminder letter to the practitioner potentially increased the rate of return for a repeat smear test by 18% in group A and 24% in group B. Adherence to the recommendation for a repeat test increased with increasing age. CONCLUSIONS--Achieving high rates of follow up smear tests and appropriate management in women with cytological abnormalities is critical to the impact of a screening programme for cervical cancer. The reminder system used in this study was not labour intensive or expensive and provided a fail safe mechanism for ensuring that reports of abnormal smears were not overlooked.     

Review of cervical smears from 76 women with invasive cervical cancer: cytological findings and medicolegal implications

OBJECTIVE: To review cervical smears from 76 women which were taken prior to the diagnosis of invasive cervical cancer and to determine the appropriateness of the cytology reports issued on the smears. METHODS: Cervical smears, clinical records, cervical smear history and cytology reports from 76 women with invasive cervical cancer were reviewed. After microscopic review of the cervical smears, the cases were divided into two groups: Group 1 comprised 50 women who were found to have had at least one false-negative (F/N) smear report prior to the diagnosis of invasive cervical cancer. Group 2 comprised 26 women for whom no evidence of F/N reporting was found. RESULTS: A total of 209 cervical smears from the 50 women in group 1 were available for review (range 2-12 smears per woman); 100 of the 209 smears were considered to have been reported appropriately. Ninety-seven smears which had been reported originally as negative or inadequate were found, on review, to contain numerous severely dyskaryotic cells and were reclassified as F/N smears. All of the 50 women had at least one F/N smear and 29 had two or more. Twelve smears from eight women contained only a few (<200 severely dyskaryotic cells). Forty women developed invasive squamous carcinoma and 10 developed invasive adenocarcinoma. The stage at diagnosis ranged from 1A to stage 4. Seventy-one smears from the 24 women in group 2 were available for review (range 1-15 smears per woman). In two cases included in group 2, no smears were provided for review as the smears had been lost or mislaid. Review of the 71 smears confirmed the accuracy of the original cytological classification of the smear. Nineteen women were diagnosed with squamous cancer, two microinvasive cancer, one glassy cell, two adenocarcinomas, and one with adenosquamous carcinoma. One women was found to have an embryonal rhabdomyosarcoma of the corpus uteri involving the cervix. DISCUSSION/CONCLUSION: The medicolegal implications are discussed in the light of the above findings. Evidence of breach of duty of care was presented in all 50 cases in group I although causation was not established in every case. There was no evidence of failure of duty of care in terms of the standard of the cervical cytology reports issued or standard of clinical management in 17 of the 26 cases in group 2. However, in seven of the 26 cases in group 2, clinical management of the case was substandard due to failure to investigate symptoms of irregular bleeding regardless of a negative cytology report (two cases), failure to act upon a suspicious smear report or consecutive inadequate smear reports (two cases), failure of follow-up after treatment of CIN3 (two cases) and histological misdiagnosis (one case).     

Long term follow up of women with borderline cervical smear test results: effects of age and viral infection on progression to high grade dyskaryosis.

OBJECTIVE--To follow up and assess the significance of borderline change in cervical smears. DESIGN--Retrospective study of women undergoing routine cervical cytological screening in 1981. SETTING--Avon Cervical Screening Programme, covering 250,000 women in Bristol and Weston super Mare. SUBJECTS--437 women showing borderline cervical changes in 1981 and 437 age matched controls with normal results in 1981. MAIN OUTCOME MEASURES--Cytological progression to high grade dyskaryosis (cervical intraepithelial neoplasia grade III or invasive carcinoma). RESULTS--During follow up ranging from 13 to 106 months 98 of the 437 women (22.4%) with borderline cytological changes on routine cervical cytology screening had a subsequent smear test showing high grade dyskaryosis compared with three of the 437 women (0.9%) in the control group. The risk of progression was greater in women aged 20 to 39 than in those aged 40 and over. Human papillomavirus infection had initially been diagnosed cytologically in 101 of the 437 (23%) women with borderline results. Significantly fewer of these women developed high grade dyskaryosis (13/98 (13%) v 88/339 (26%), p less than 0.05). CONCLUSIONS--Women with borderline smear test results are at increased risk of developing high grade dyskaryosis, particularly if the borderline changes occur without cytological features of human papillomavirus infection. Progression occurs within three years in 50% of cases, although a linearly increasing risk was sustained over the nine years of follow up and was greatest in women aged 20 to 39. Careful follow up of these women is indicated.     

Outcome of three consecutive inadequate cervical smears

A retrospective audit of women with three consecutive inadequate cervical smears during 1998-99 was conducted at Birmingham Heartlands Hospital. The commonest reasons were obscured by polymorphs (34.5%) and sparse cellularity (28.9%). Seventy-three per cent (73%) were followed up at colposcopy and 22.1% had histological assessment; 15.9% of women had an abnormality detected, 10.6% with abnormal histology and 5.3% with a cytological abnormality only. Cytological abnormalities were seen in 11.1% of the screening population. This study did not identify a cytological criterion to differentiate those that would or would not have an abnormality on follow-up. It is suggested that all women with three consecutive inadequate smears should have adequate follow-up, although this may place increased demands on colposcopy services.     

Outcome analysis of 4 years' follow-up of patients referred for colposcopy with one smear showing mild dyskaryosis

Objective: To assess the 4‐year outcome of patients after one smear showing mild dyskaryosis with respect to smear regression rate, prevalence of cervical intraepithelial neoplasia (CIN) and the effect of age. Methods: Retrospective analysis of patients diagnosed with initial mildly dyskaryotic smear during the year 2000 with a follow‐up period of 48 months. These women had not had any previous abnormal smears. Settings: Cytopathology Department and Colposcopy Unit, King’s College Hospital, London, UK. Results: We identified 524 patients of whom 375 patients with complete follow‐up data are included. The age range was 19–67 years with a median of 29 years. There were 207 patients aged 35 years or less (55%). At 6 months, 258 smears were performed and 47.8% of them were negative (95% CI: 41.6–54.0%). The total number of negative follow‐up smears in the first year was 198 out of a total of 397 smears performed (50%). This proportion has significantly increased between 1 and 4 years’ follow‐up to 67.5% (RR: 1.24; 95% CI: 1.14–1.35). Over the 4‐year period, 791 smears were performed and 477 were negative (60.3%; 95% CI: 56.9–63.7%). Of the 477 negative smears there were only 61 smears (12.8%; 95% CI: 10–16%), in 54 patients (14%; 95% CI: 11–18%) that reverted back to low‐grade cytological abnormality. In only one case the repeat smear showed high‐grade abnormality after initial negative follow‐up; however, on biopsy, histology showed CIN I. Out of the 375 patients, 70 required treatment with excisional biopsy (19%; 95% CI: 15.0–22.9%). Histology confirmed high‐grade CIN in only 41 cases giving a prevalence of 11% (95% CI: 8.1–14.5%). There were no cases of microinvasive or invasive cancer detected. Age (≤35 years versus >35 years) did not significantly affect either cytological or histological outcome. Conclusion: Sixty per cent of follow‐up smears after initial mild dyskaryosis subsequently became negative; of them 87.2% remained negative over the 4 year follow‐up. Treatment was only required in 19% of patients, with 11% prevalence of high‐grade CIN. Age did not affect the outcome. These results are reassuring and indicate that colposcopic referral may not be necessary after only one mildly dyskaryotic smear.     

Loop diathermy excision of the cervical transformation zone in patients with abnormal cervical smears.

OBJECTIVE--To determine the efficacy and morbidity of fine loop diathermy excision of the cervical transformation zone as applied to the management of outpatients with abnormal cervical smears. DESIGN--Prospective programme trial with six month follow up. SETTING--Two hospital based colposcopy clinics. PATIENTS--616 Patients aged 16-60 with abnormal cervical smears. INTERVENTIONS--After colposcopic and cytological assessment excision of the cervical transformation zone by fine loop diathermy under local anaesthesia in the outpatient department. MAIN OUTCOME MEASURES--Time to complete the treatment, immediate morbidity in terms of discomfort and bleeding, and cytological and colposcopic findings at six months. RESULTS--Treatment was completed in a mean of 3.47 minutes (SD 1.99). Immediate morbidity was minimal, and histological specimens were adequate in over 90% of cases. Almost two thirds of patients were treated at their first visit to the clinic. 58 Patients (9.4%) failed to attend for follow up at six months and one had had a hysterectomy. Of the 557 patients who attended for colposcopic and cytological follow up at six months, 506 (91%) were normal cytologically and 19 (3.4%) had histologically confirmed persistence of cervical intraepithelial neoplasia. The overall confirmed failure rate of the technique was 4.4%. CONCLUSION--Loop diathermy excision is an effective treatment with low morbidity and is an appropriate modality for patients with abnormal cervical smears.     

Invasive cancer of the cervix in women with mild dyskaryosis followed up cytologically.

Mildly dyskaryotic smears are common, and women with such results are often followed up with further cervical smear tests. An important consideration in evaluating this practice would be the annual incidence of invasive cervical cancer. A reanalysis of five previous studies of the cytological follow up of women with mildly abnormal smear test results was undertaken to calculate this incidence. The annual incidence of invasive cancer in these women ranged from 0 to 420 per 100,000 women years. The large studies providing the most precise estimates had annual rates of 143 to 420 per 100,000 women years. This is 16 to 47 times greater than in women aged 15-34 years in England and Wales. The average rate was 208 per 100,000 women years. Women with mild dyskaryosis are at high risk of developing invasive cervical cancer despite cytological follow up. A full appraisal of the costs and benefits of colposcopy in this situation is urgently required.     

Comparison of Monoclonal Antibodies Aua1 and Ber Ep4 With Anti-Cea For Detecting Carcinoma Cells In Serous Effusions and Distinguishing Them From Mesothelial Cells

Commercially available monoclonal antibodies AUA1, BER EP4 and carcinoembryonic antigen (CEA) were applied to cell blocks from 95 serous effusions. AUA1 and BER EP4 were reactive with 89% of effusions known to contain carcinoma cells, and anti-CEA with 71%. They also reacted with cells in two effusions from patients with malignant disease which were regarded as negative on conventional cytological examination of Papanicolaou-stained smears. They were negative in all but one of the benign effusions. Using all three antibodies, 95% of effusions containing carcinoma cells were detected. Use of these antibodies could improve the cytological diagnosis of serous effusions.     

Cervical intraepithelial neoplasia grade III (CIN III) and invasive cervical carcinoma: the yawning gap revisited and the treatment of risk

In a 3-year study of the population of Southampton and south-west Hampshire there were 10 times as many cases of CIN III compared with invasive squamous carcinoma (700 compared with 70). The peak incidence of CIN III per 1000 screened women years was in those aged 25-29 years, which was 20 years earlier than the peak incidence of invasive cervical cancer per 1000 women years at risk. Ninety percent of CIN III was diagnosed in women under 50 years. There were 14 cases of cervical glandular intraepithelial neoplasia grade III (CGIN III), three coexisting with CIN III, all in women aged under 50 years: the gap between intraepithelial and invasive lesions was not seen for glandular neoplasia. Although referral was for at least moderate dyskaryosis in 86.8% of women with CIN III or CGIN III, most had been screened previously, either having had mild abnormalities requiring repeat cytology (39.8%) or negative cytology (34.5%). Only 12 women aged > or = 50 years had previous negative cytology: 21.4% compared with 35.6% of women aged < 50 years (P = 0.034). The results of this study suggest that the best opportunity for preventing invasive squamous cell carcinoma lies in screening women aged 20-39 years when the incidence of CIN III in the screened population is highest and before the peak incidence of invasive disease. The results also indicate the importance of repeated screening and follow up of minor cytological abnormalities in the detection of CIN III. The benefit of screening must be regarded as a treatment of risk, since it is almost certain that a high proportion of CIN III regresses or persists unchanged.

Neuroendocrine ductal carcinoma in situ of the breast: cytological features in 32 cases Objective: The purpose of this study was to clarify the cytological features of neuroendocrine ductal carcinoma in situ (NE‐DCIS) of the breast. Methods: We analysed the cytopathological findings in 22 fine needle aspiration (FNA) smears and 17 nipple discharge smears obtained from 32 Japanese patients with NE‐DCIS. Results: The background of the FNA smears was clear (59%), mucoid (23%), haemorrhagic (14%) or necrotic (5%). Most of the FNA smears (95%) showed high cellularity. Characteristically, NE‐DCIS cells were loosely arranged in three‐dimensional solid clusters or singly dispersed. Well‐developed vascular cores with or without malignant cells were occasionally recognized. The tumour cells were polygonal or spindle‐shaped with a fine granular, abundant cytoplasm. Nuclei with finely granular chromatin were round or oval and often eccentrically located (plasmacytoid appearance). Mitotic figures were infrequent. Nuclear grade was estimated to be low in 86%. Most nipple discharge smears had fairly low cellularity with poorly preserved cell clusters in a markedly haemorrhagic background, although two (12%) were extremely cellular with cytological characteristics similar to those of the FNA smears. Pre‐operative cytological malignant diagnoses were made in 42% of FNA smears and 0% of nipple discharge smears. Immunohistochemistry for neuroendocrine markers (chromogranin A and synaptophysin) confirmed the neuroendocrine nature of this tumour in adequate cytological specimens. Conclusions: NE‐DCIS has distinctive cytological features and can therefore be diagnosed as a neuroendocrine tumour in most FNAs and some nipple discharge smears by cytological examination employing immunohistochemical techniques. We emphasize that a breast lesion with these features may be in situ and not invasive, and also that there is a risk of under‐diagnosis.     

Screening for cervical cancer: a new scope for general practitioners? Results of the first year of colposcopy in general practice.

A survey was carried out over one year of all the women who attended a colposcopy clinic in a general practice. During the year 1254 women underwent cytological screening in the practice and 197 of these underwent colposcopy. Of 79 women with abnormal smears that suggested cervical intraepithelial neoplasia, 62 (79%) were confirmed by biopsy to have cervical premalignancy. In addition, the remaining 118 women with normal or inflammatory smears underwent colposcopy either because of their history or because they requested the investigation. A general underestimate of cervical intraepithelial neoplasia when cytology alone was used was discovered. Seven out of 28 women with inflammatory smears were found to have important cervical premalignancy. Mildly dyskaryotic smears led to a falsely reassuring estimate of the degree of severity of cervical lesions. Seven out of 13 patients who underwent colposcopy because they were thought to be at high risk of neoplasia because of a history of genital warts, unexplained recurrent cystitis, heroin abuse, or immunosuppression had cervical intraepithelial neoplasia proved at biopsy. This report shows that both in screening for and in the follow up of known cervical disease a normal smear cannot guarantee normal pathology. Diagnostic colposcopy is a valuable complementary investigation that could be carried out in a general practice.     

Is Screening for Cancer Worth While? Results from a Well-woman Clinic for Cancer Detection

1,768 women were screened for breast and cervical cancer in the year May 1968 to April 1969. Clinical examination followed the completion of a simple questionary. Investigations included thermography and mammography of the breast and cytology of the cervical and vaginal smears. Breast cancer was detected in 15 patients (0·85% or 8·5 per 1,000) and none was aware of any abnormality though 13 of the tumours were clinically palpable. Carcinoma in situ of the cervix was found in a further eight (0·45% or 4·5 per 1,000).     

Pollen grains in human cytology

This paper reports on pollen analyses carried out in the course of a ten-year investigation, on many thousands of cytological smears coming from various organs and systems of the human body, and prepared for diagnostic purposes. The frequency and the significance of the pollen records vary according to the specific cytological field taken into account. In the urinary sediment smears, nipple secretions, and needle aspirations the polliniferous smears are very few, and the pollen number per smear is low (max 14 pollen grains, belonging always or mostly to anemophilous species). In these cases, the pollen records evidence the airborne contamination during medical procedures, the same happens with most of cervico-vaginal smears. In some cervico-vaginal smears, the high frequency of pollen grains belonging to pharmaceutical taxa suggests that lavages with vegetable components were used by the patients before undergoing the test. In nasal, bronchial and conjunctival cytology greater amounts of polliniferous slides were recorded (in bronchial/nasal cytology also a higher number of pollen grains per smears, up to 114–428 respectively) and pollen spectra reflected the vegetational environment of the patients' living sites. In these cases, most pollen grains are thought to be really present on mucosae when the samples were taken. In these cytological fields pollen analysis may be useful for diagnostic purposes, above all in case of allergic pathology to detect the pollen grains causing the disease.     

Screening for cervical intraepithelial neoplasia in north east Scotland shows fall in incidence and mortality from invasive cancer with concomitant rise in preinvasive disease.

OBJECTIVE--To assess the effect of screening for cervical intraepithelial neoplasia on the incidence of and mortality from invasive squamous cell carcinoma of cervix in north east Scotland and to discover why cases of invasive cancer still occur. DESIGN--(a) Analysis of data on cases of cervical intraepithelial neoplasia obtained from the cytology data bank; (b) analysis of data on 612 women presenting with invasive squamous cancer during 1968-91, obtained from cancer registry and hospital records; (c) analysis of death rates obtained from the registrar general''s (Scotland) annual reports, the Information Services Division of the Home and Health Department (Scotland), and local records for 1974-91; (d) case-control studies on 282 cases of invasive cancer and 108 deaths which occurred in 1982-91. Cases were matched with two controls both for age and for having a negative smear test result at the time of presentation of the case. SETTING--North east Scotland (Grampian region, Orkney, and Shetland). SUBJECTS--Women (n = 306,608) who had had cervical smear tests between 1960 and 1991. RESULTS--There had been a substantial increase in cases of cervical intraepithelial neoplasia grade III since 1982. The incidence of invasive cancer has fallen since the start of screening in 1960, the fall occurring mainly in the well screened age group 40-69 years. There was a rise in women aged under 40 and over 70. Women with invasive disease seen between 1982 and 1991 mostly presented at stage I. Of these, half were unscreened, one third were poorly screened, 11% were found in retrospect to have had abnormal cells, 3% had recurrence of disease after treatment for cervical intraepithelial neoplasia grade III, and 3% were lost to follow up. Death rates had fallen, most noticeably in women aged 45-64, who had had the opportunity to be screened and rescreened. There was a disturbing rise in deaths among women under 45. Most deaths (65%) occurred in unscreened women. Case-control studies showed that the longer the time and absence of a smear test before presentation the higher was the risk of invasive cancer and of death. CONCLUSIONS--Screening has been effective in reducing the incidence of and mortality from cervical cancer in north east Scotland. Most cases and deaths occurred in unscreened women or in those who had had few smears at long intervals. An increase in cases of cervical intraepithelial neoplasia grade III in women screened for the first time occurred during 1982-91.     

Management of Women With A Cervical Smear Showing A Mild Degree of Dyskaryosis: A Review of Policy

Three hundred and thirty-seven women who presented for the first time with a cervical smear showing a mild degree of dyskaryosis were followed for a minimum period of 3 years and 9 months. Of the 305 women with complete cytological and histological records, 178 were biopsied and 127 remained on cytological follow up. In the biopsied group one case of microinvasive squamous cell carcinoma was diagnosed within 1 year of the patient's first abnormal smear. A further 24% showed cervical intraepithelial neoplasia (CIN) I, 17% showed CIN II and 29% showed CIN III. The overall regression rate for the group of 305 women was 34%. Our results indicate that cytological surveillance is acceptable provided that biopsy is advised when dyskaryosis persists. No major modifications to laboratory policy are indicated and in approximately 34% of cases an unnecessary hospital referral would be avoided.     

High Uptake of HIV Testing in Pregnant Women in Ontario,Canada

In 1999, Ontario implemented a policy to offer HIV counseling and testing to all pregnant women and undertook measures to increase HIV testing. We evaluated the effectiveness of the new policy by examining HIV test uptake, the number of HIV-infected women identified and, in 2002, the HIV rate in women not tested during prenatal care. We analyzed test uptake among women receiving prenatal care from 1999 to 2010. We examined HIV test uptake and HIV rate by year, age and health region. In an anonymous, unlinked study, we determined the HIV rate in pregnant women not tested. Prenatal HIV test uptake in Ontario increased dramatically, from 33% in the first quarter of 1999 to 96% in 2010. Test uptake was highest in younger women but increased in all age groups. All health regions improved and experienced similar test uptake in recent years. The HIV rate among pregnant women tested in 2010 was 0.13/1,000; in Toronto, the rate was 0.28 per 1,000. In the 2002 unlinked study, the HIV rate was 0.62/1,000 among women not tested in pregnancy compared to 0.31/1,000 among tested women. HIV incidence among women who tested more than once was 0.05/1,000 person-years. In response to the new policy in Ontario, prenatal HIV testing uptake improved dramatically among women in all age groups and health regions. A reminder to physicians who had not ordered a prenatal HIV test appeared to be very effective. In 2002, the HIV rate in women who were not tested was twice that of tested women: though 77% of pregnant women had been tested, only 63% of HIV-infected women were tested. HIV testing uptake was estimated at 98% in 2010.
