Role of HPV in the Prediction of Persistence/Recurrence After Treatment for Cervical Precancer.

OBJECTIVES: (1) To determine the role of human papillomavirus (HPV) testing after excisional treatment of cervical precancer. (2) To determine clinical factors associated with persistence of cervical precancer post-treatment. METHODS: A retrospective chart review was conducted including patients who had a loop electrosurgical excision procedure (LEEP) for cervical precancer (cervical intraepithelial neoplasia 3/adenocarcinoma in situ/high-grade squamous intraepithelial lesions [HSIL]). All patients treated between 2016 and 2018 at a tertiary centre colposcopy unit were included. Persistence/recurrence of disease was defined as high-grade cytology or histology identified during the time of follow-up. Univariate and multivariate regression models were performed to identify factors associated with persistence/recurrence and HPV positivity at exit testing. RESULTS: A total of 284 patients were included. The median follow-up time was 19 months. Of the LEEP specimens, 90.8% (n = 258) demonstrated HSIL and 3.9% (n = 11) had adenocarcinoma in situ. 28.5% (n = 81) of the LEEP specimens had positive margins. In follow-up, 72.9% had negative cytology, 17.6% had atypical squamous cells of undetermined significance/low-grade SIL, 1.8% had atypical squamous cells, HSIL cannot be excluded/low-grade SIL-H, and 6.7% had HSIL. At the final follow-up, 27.8% (n = 79) were HPV+. Overall rate of persistence/recurrence was 11.3% (n = 32); median time to persistence/recurrence was 6.5 months. Multivariate regression models demonstrated that follow-up HPV positivity (OR = 22.0) and positive margins (OR = 3.7) were significantly associated with persistence/recurrence. Similarly, in univariate regression models, positive margins were significant (OR = 2.2) for predicting HPV positivity in exit testing. CONCLUSIONS: Persistence/recurrence of precancer can occur due to incomplete treatment of lesions by local excision and by the persistence of HPV infection. Surveillance strategies for women treated for cervical precancer require a risk-based approach and should rely on HPV testing.

A National Survey of Canadian Physicians on HPV: Knowledge, Barriers, and Preventive Practices.

OBJECTIVE: Physicians are the sole prescribers of the human papillomavirus (HPV) vaccine for adults in Canada. This survey of Canadian physicians aimed to explore knowledge, barriers, and preventive practices regarding HPV vaccination. METHOD: A survey of general practitioners (GPs) (n = 337) and obstetrician/gynaecologists (OB/GYNs) (n = 81) was conducted in May and June 2016 using an online panel. Demographic data and information pertaining to HPV knowledge, attitudes, and vaccination practices were collected by using a 22-item questionnaire. RESULTS: A total of 83% of GPs recommended or administered HPV vaccine to adults. Among physicians, 99% to 100% strongly agreed that vaccination is an important aspect of disease prevention. Physicians were rarely concerned about vaccine safety (5%-11%). Cost was seen as the number one barrier by 92% to 95% of physicians. Physicians rated consumers' understanding of HPV to be low (11%-14%, very good; and 49%-56%, somewhat good knowledge). Among physicians, 60% to 66% of said they routinely discussed HPV vaccination with patients. Female physicians demonstrated greater knowledge of HPV than their male counterparts. CONCLUSION: GPs and obstetrician/gynaecologists routinely recommend and administer the HPV vaccine to patients. The majority of physicians showed high levels of knowledge regarding HPV vaccine and associated cancers; however, perceived barriers of cost may limit recommendations for vaccination, particularly among older women or men.

A National Survey of Canadian Adults on HPV: Knowledge, Attitudes, and Barriers to the HPV Vaccine.

OBJECTIVE: Identifying human papillomavirus (HPV) vaccination motivators and barriers among adults could lead to new approaches to improve HPV vaccination rates in non-pediatric populations. This Canadian survey aimed to assess current knowledge of, attitudes towards, and barriers to the HPV vaccine among the general public. METHODS: An online panel was used to survey HPV unvaccinated women (n = 802) and vaccinated women (n = 250) 18 to 45 years old, as well as 18- to 26-year-old men (n = 200), in May and June 2016. A 16-item questionnaire collected data on sociodemographic factors, health-seeking behaviours, knowledge of HPV infection and its consequences, and the HPV vaccine. Data were stratified by sex and by vaccination status among women. RESULTS: The majority of individuals somewhat or strongly agreed that vaccination is an important aspect of disease prevention (vaccinated women, 93%; unvaccinated women, 85%; and men, 59%). However, a high proportion of patients were concerned about vaccine safety (vaccinated women, 26%; unvaccinated women, 40%; and men, 36%). Moreover, 58% to 61% of participants were generally cautious about taking any vaccine. The number one reported barrier to vaccination was not having a recommendation from a doctor (38%). Cost was seen as a barrier by only 18% to 20% of participants. CONCLUSION: Canadian participants show a broad diversity in HPV knowledge and regarding barriers to vaccination. The youngest populations (vaccinated women and men) showed higher levels of knowledge regarding HPV.

Betwixt and Between Well and Sick in Cervical Precancer: Canadian Women's Experiences of Recurring HPV Infections and HPV Vaccination.

Background This research fuses the experiences of a precancer diagnosis with the decision-making surrounding a vaccine that can protect against human papillomavirus strains that women may not have been exposed to. The interviewee cohort is of note as half the women were in their 30s and 40s and 75% were over the age of 26. These groupings are often overlooked in media discourses and narrative research surrounding human papillomavirus and the human papillomavirus vaccine. Purpose Womens' diagnoses and treatment experiences, including colposcopies, biopsies, and Loop Electrosurgical Excision Procedures, are chronicled to highlight a liminal, precancerous state-one in which they are not deemed healthy, but nor have they been diagnosed with cancer. These are emotion-filled experiences that are ridden with anxiety and fear, but also ones that are structured with self-care strategies to contain human papillomavirus infections and the risk of cervical cancer. Methods Twenty women who attended Sunnybrook Health Sciences Centre's human papillomavirus vaccination clinic were interviewed and their narratives were documented and analyzed to determine their experiences surrounding human papillomavirus infections and precancer as well as their motivations for human papillomavirus vaccination. Results The decision to undergo human papillomavirus vaccination was a self-care strategy that accompanied treatment procedures and was a means to reduce cervical cancer risk. While encouraged with the human papillomavirus vaccine's potential to curb cervical cancer, they had a tempered view of the vaccine and its effectiveness in their cases, given their medical histories. Conclusions The research provides an in-depth accounting of an often overlooked grouping in human papillomavirus and human papillomavirus vaccination research and media discourse which, generally, focuses upon middle-school-aged girls and university-/college-aged women. In addition, the research provides recommendations for practice for cervical precancer diagnoses going forward.

Complementary and hormonal therapy for vasomotor symptom relief: a conservative clinical approach.

Vasomotor symptoms are the most common menopausal symptom experienced by women and the leading reason menopausal women seek health care advice. The recent shift towards a more conservative use of hormone therapy (HT) during menopause has prompted the need for treatment regimens to be individualized according to symptom severity. Our objective was to develop a new algorithm that enables practitioners to customize treatment regimens according to symptom severity. In order to develop a comprehensive treatment algorithm, we conducted a literature review and considered the findings from recently published treatment guidelines from around the world. We also evaluated the results of systematic reviews investigating the efficacy and safety of complementary and alternative medicines. We found a growing trend away from prescription HT in women with mild to moderate symptoms and an increasing trend toward lifestyle modification and the use of complementary and alternative medicines. On the basis of these findings, we have developed an algorithm that accounts for symptom severity. The algorithm presented here provides treatment options based on symptom severity and a comprehensive approach for integrating lifestyle modifications and complementary therapies with prescription treatment regimens.

The use of oral misoprostol as a cervical ripening agent in operative hysteroscopy: a double-blind, placebo-controlled trial.

OBJECTIVE: The purpose of this study was to assess the effectiveness of oral misoprostol as a cervical ripening agent when used in operative hysteroscopy. STUDY DESIGN: This was a double-blind, placebo-controlled trial. Any patient undergoing an operative hysteroscopy (with a 9-mm to 10-mm hysteroscope) was considered eligible for the trial. Patients were randomly allocated, by means of computer-generated numbers, to receive either placebo or 400 microg of misoprostol 12 and 24 hours before surgery. The primary outcome measure in this study was the ease of cervical dilatation as measured by the largest-number Hegar dilator that could be inserted into the cervix without resistance. A subjective assessment of the ease of dilatation was also recorded on a Likert scale. Other demographic data including age, menopausal status, parity, and use of gonadotropin-releasing hormone (GnRH) analogues were also recorded. Adverse effects experienced and any other adverse outcomes were also recorded for each group. Logistic regression analysis was used to compare the two groups. RESULTS: Two hundred four patients were recruited into the study. There were no differences between the two groups in demographic variables. The misoprostol group demonstrated an increased ease of cervical dilatation (odds ratio [OR] 2.6; CI 1.28-5.29; P =.008). This was also demonstrated in the subgroup of patients who were menopausal or who had been pretreated with a gonadotropin-releasing hormone analog (OR 2.49; CI 1.11-5.58; P =.026), as well as in those who were premenopausal (OR 2.15; CI 1.04 4.45; P =.04). There were no differences between the two groups in the time required for dilatation (P =.08) or ease of dilatation (P =.12). Adverse effects were greater in the treatment group: diarrhea (28% vs 4%; P <.001), cramps (27% vs 1%; P <.0001), and bleeding (26% vs 1.3%; P <.001). CONCLUSIONS: Misoprostol demonstrates a benefit over placebo in the ease of cervical dilatation in premenopausal and postmenopausal women and in those pretreated with a gonadotropin-releasing hormone analog. Adverse effects were more common in the treatment group but did not preclude the patients from taking the medication.
