Summary Endometrial cancer is one of the gynaecological cancers that carries good overall prognosis because it is often detected at early stages of disease. The International Federation of Gynecology ...and Obstetrics replaced clinical staging with surgical staging in 1988 and updated the system in 2009. Controversies remain regarding the recommended screening protocol for women with a high risk of endometrial cancer, the role and benefit of retroperitoneal lymph-node dissection, the necessity of ovarian resection, the benefit and type of adjuvant radiation therapy, and the safety of hormone-replacement therapy after treatment. This article reviews the available evidence for optimum management of endometrial cancer and how management strategies can be applied in Asian countries with different levels of health-care resource availability and economic development. An overview of the literature for endometrial-cancer screening, diagnosis, and management is discussed. Consensus statements are formulated on the basis of basic, limited, enhanced, and maximum health-care resource availability, using the framework provided by the Breast Health Global Initiative.
Quadrivalent human papillomavirus (HPV) vaccine has been shown to provide protection from HPV 6/11/16/18-related cervical, vaginal, and vulvar disease through 3 years. We provide an update on the ...efficacy of the quadrivalent HPV vaccine against high-grade cervical, vaginal, and vulvar lesions based on end-of-study data from three clinical trials. Additionally, we stratify vaccine efficacy by several baseline characteristics, including age, smoking status, and Papanicolaou (Pap) test results. A total of 18,174 females ages 16 to 26 years were randomized and allocated into one of three clinical trials (protocols 007, 013, and 015). Vaccine or placebo was given at baseline, month 2, and month 6. Pap testing was conducted at regular intervals. Cervical and anogenital swabs were collected for HPV DNA testing. Examination for the presence of vulvar and vaginal lesions was also done. Endpoints included high-grade cervical, vulvar, or vaginal lesions (CIN 2/3, VIN 2/3, or VaIN 2/3). Mean follow-up time was 42 months post dose 1. Vaccine efficacy against HPV 6/11/16/18-related high-grade cervical lesions in the per-protocol and intention-to-treat populations was 98.2% 95% confidence interval (95% CI), 93.3-99.8 and 51.5% (95% CI, 40.6-60.6), respectively. Vaccine efficacy against HPV 6/11/16/18-related high-grade vulvar and vaginal lesions in the per-protocol and intention-to-treat populations was 100.0% (95% CI, 82.6-100.0) and 79.0% (95% CI, 56.4-91.0), respectively. Efficacy in the intention-to-treat population tended to be lower in older women, women with more partners, and women with abnormal Pap test results. The efficacy of quadrivalent HPV vaccine against high-grade cervical and external anogenital neoplasia remains high through 42 months post vaccination.
Background. A quadrivalent (types 6, 11, 16, and 18) human papillomavirus (HPV) L1 virus-like-particle (VLP) vaccine has been shown to be 95%–100% effective in preventing cervical and genital disease ...related to HPV-6, -11, -16, and -18 in 16–26-year-old women naive for HPV vaccine types. Because most women in the general population are sexually active, some will have already been infected with ⩾1 HPV vaccine types at the time vaccination is offered. Here, we assessed whether such infected women are protected against disease caused by the remaining HPV vaccine types. Methods. Two randomized, placebo-controlled trials of the quadrivalent (types 6, 11, 16, and 18) HPV vaccine enrolled 17,622 women without consideration of baseline HPV status. Among women infected with 1–3 HPV vaccine types at enrollment, efficacy against genital disease related to the HPV vaccine type or types for which subjects were naive was assessed. Results. Vaccination was 100% effective (95% confidence interval CI, 79%–100%) in preventing incident cervical intraepithelial neoplasia 2 or 3 or cervical adenocarcinoma in situ caused by the HPV type or types for which the women were negative at enrollment. Efficacy for preventing vulvar or vaginal HPV-related lesions was 94% (95% CI, 81%–99%). Conclusions. Among women positive for 1–3 HPV vaccine types before vaccination, the quadrivalent HPV vaccine protected against neoplasia caused by the remaining types. These results support vaccination of the general population without prescreening.
Independent, prospective, multicenter, hospital-based cross-sectional studies were conducted across 5 countries in Asia, namely, Malaysia, Vietnam, Singapore, South Korea, and the Philippines. The ...objectives of these studies were to evaluate the prevalence of human papillomavirus (HPV) types (high risk and others including coinfections) in women with invasive cervical cancer (ICC) and high-grade precancerous lesions.
Women older than 21 years with a histologic diagnosis of ICC and cervical intraepithelial neoplasia CIN 2 or 3 and adenocarcinoma in situ (AIS) were enrolled. Cervical specimens were reviewed by histopathologists to confirm the presence of ICC or CIN 2/3/AIS lesion and tested with short PCR fragment 10-DNA enzyme immunoassay-line probe assay for 14 oncogenic HPV types and 11 non-oncogenic HPV types. The prevalence of HPV 16, HPV 18, and other high-risk HPV types in ICC including squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (ADC/ASC) and CIN 2/3/AIS was estimated.
In the 5 Asian countries, diagnosis of ICC was confirmed in 500 women SCC (n = 392) and ADC/ASC (n = 108), and CIN 2/3/AIS, in 411 women. Human papillomavirus DNA was detected in 93.8% to 97.0% (84.5% for the Philippines) of confirmed ICC cases 94.0%-98.7% of SCC; 87.0%-94.3% (50.0% for the Philippines) of ADC/ASC and in 93.7% to 100.0% of CIN 2/3/AIS. The most common types observed among ICC cases were HPV 16 (36.8%-61.3%), HPV 18 (12.9%-35.4%), HPV 52 (5.4%-10.3%), and HPV 45 (1.5%-17.2%), whereas among CIN 2/3/AIS cases, HPV 16 (29.7%-46.6%) was the most commonly observed type followed by HPV 52 (17.0%-66.7%) and HPV 58 (8.6%-16.0%).
This article presents the data on the HPV prevalence, HPV type distribution, and their role in cervical carcinogenesis in 5 Asian countries. These data are of relevance to public health authorities for evaluating the existing and future cervical cancer prevention strategies including HPV-DNA testing-based screening and HPV vaccination in these Asian populations.
In the quadrivalent (types 6/11/16/18) HPV vaccine (GARDASIL/SILGARD) clinical program, 73% of women aged 16-26 were naïve to all vaccine HPV types. In these women, prophylactic administration of the ...vaccine was highly effective in preventing HPV 6/11/16/18-related cervical disease. Of the remaining women, 15% of had evidence of past infection with one or more vaccine HPV types (seropositive and DNA negative) at the time of enrollment. Here we present an analysis in this group of women to determine the efficacy of the HPV 6/11/16/18 vaccine against new cervical and external anogenital disease related to the same vaccine HPV type which had previously been cleared. Vaccine tolerability in this previously infected population was also assessed.
18,174 women were enrolled into 3 clinical studies. The data presented comprise a subset of these subjects (n = 2,617) who were HPV seropositive and DNA negative at enrollment (for >or=1 vaccine type). In each study, subjects were randomized in a 1:1 ratio to receive HPV 6/11/16/18 vaccine or placebo at day 1, month 2 and month 6 (without knowledge of baseline HPV status). Procedures performed for efficacy data evaluation included detailed genital examination, Pap testing, and collection of cervicovaginal and external genital specimens. Analyses of efficacy were carried out in a population stratified by HPV serology and HPV DNA status at enrollment.
Subjects were followed for an average of 40 months. Seven subjects in the placebo group developed cervical disease, and eight subjects developed external genital disease related to a vaccine HPV type they had previously encountered. No subject receiving HPV 6/11/16/18 vaccine developed disease to a vaccine HPV type to which they were seropositive and DNA negative at enrolment.
These results suggest that natural HPV infection-elicited antibodies may not provide complete protection over time, however the immune response to the HPV 6/11/16/18 vaccine appears to prevent reinfection or reactivation of disease with vaccine HPV types. Vaccine-related adverse experiences were higher among subjects receiving vaccine, mostly due to increased injection site adverse experiences.
To review our experience with secondary cytoreductive surgery for recurrent epithelial ovarian cancer with regard to its feasibility, morbidity, mortality, patient selection, and survival.
Forty-six ...patients who underwent secondary cytoreductive surgery at the Royal Hospital for Women, Sydney, between July 1988 and October 1996 were retrospectively reviewed. The mean age at surgery was 50.3 years, and the median disease-free interval was 26 months. Eighty-nine percent of patients had a disease-free interval of at least 12 months. Twenty-five patients (54%) had localized disease at the time of surgery. Univariate survival outcomes were analyzed using the log rank test, and survival curves were calculated using the method of Kaplan-Meier.
Two patients (4%) were inoperable and 19 patients (41%) were cytoreduced to no macroscopic disease. There was one postoperative death (2%), and four patients (8.7%) had significant postoperative morbidity. With a median follow-up of 88 months, the overall median survival was 22.5 months. Patients with a disease-free interval of less than 12 months after their initial treatment had a median survival of 6 months, compared with 11 months if the disease-free interval was 12-24 months and 39 months for those with a disease-free interval of 24 months or more (P =.001, log rank). Patients who had any residual disease had a median survival of 11 months, whereas those with no residual disease had a median survival of 38 months (P =.002, log rank).
For carefully selected patients with recurrent epithelial ovarian cancer: 1) complete surgical resection is feasible more commonly than with primary cytoreduction, 2) serious morbidity and mortality are acceptable, and 3) significant survival benefit accrues when a) all macroscopic disease can be resected, or b) the disease-free interval is 24 months or more.
Background
Vulvar defects result chiefly from oncologic resection of vulvar tumors. Reconstruction of vulvar defects restores form and function for the purpose of coitus, micturition, and defecation. ...Many surgical options exist for vulvar reconstruction. The purpose of this article is to present our experience with vulvar reconstruction.
Methods
From 2007 to 2013, 43 women presented to us with vulvar defects for reconstruction. Their mean age at the time of reconstruction was 61.1 years. The most common cause of vulvar defect was from resection of vulvar carcinoma and extramammary Paget's disease of the vulva. Method s of reconstruction ranged from primary closure to skin grafting to the use of pedicled flaps.
Results
The main complications were that of long term hypertrophic and/or unaesthetic scarring of the donor site in 4 patients. Twenty-two patients (51%) were able to resume sexual intercourse. There were no complications of flap loss, wound dehiscence, and urethral stenosis.
Conclusions
We present a subunit algorithmic approach to vulvar reconstruction based on defect location within the vulva, dimension of the defect, and patient age and comorbidity. The gracilis and gluteal fold flaps are particularly versatile and aesthetically suited for reconstruction of a variety of vulvar defects. From an aesthetic viewpoint the gluteal fold flap was superior because of the well-concealed donor scar. We advocate the routine use of these 2 flaps for vulvar reconstruction.
The traditional approach for the treatment of endometrial cancer by laparotomy is increasingly being replaced by laparoscopic surgery. The advantages of laparoscopy have been well-documented. ...Laparoscopy avoids the morbidity of a laparotomy, overcomes the limitations of vaginal hysterectomy, provides adequate pathological information for an accurate surgical staging and expedites the postoperative recovery of patients. This paper reports the outcome of a series of 50 consecutive cases of laparoscopic hysterectomy and pelvic lymphadenectomy for endometrial cancers that were performed by the author. The objective is to review the perioperative, postoperative experience and survival outcomes of patients with endometrial cancer managed by laparoscopic surgery performed by a single surgeon.
The records of 50 consecutive patients with endometrial cancers from October 1995 to October 2007 treated by laparoscopic pelvic lymphadenectomy and laparoscopic hysterectomy (total and assisted) were retrospectively reviewed. Data on patients' attributes, endometrial cancers, surgical procedures, surgical complications and morbidity, perioperative experience, length of hospital stays and clinical outcome were analysed.
Laparoscopic surgery was successful in all 50 patients and is clearly an option for the treatment of early endometrial cancer.
Careful patient selection and surgical competency are instrumental in ensuring successful treatment.
Abstract Little is known of men's knowledge of cervical cancer and its links with human papillomavirus (HPV), or of their attitudes and beliefs about HPV vaccination. This is despite men's sexual ...behaviour contributing to HPV transmission and their potential role in deciding whether their children are vaccinated against HPV. To address this, a comprehensive survey was conducted in Singapore where plans are underway for an HPV vaccination program. A representative sample of 930 Singaporean men was found to have moderate knowledge of cervical cancer but poor knowledge and awareness of HPV. Although these men showed strong support for HPV vaccination, overall findings highlight the importance of including men in education campaigns that aim to decrease the incidence of cervical and other HPV-related cancers and to increase the uptake of HPV vaccination.
Multiple barriers impede the transformation of evidence-based research into implementation of cervical cancer screening in ASEAN countries. This review is the first of its kind to show the disease ...burden of cervical cancer, progress till date to implement screening and corresponding challenges, and propose tailored solutions to promote cervical cancer prevention in ASEAN. In 2020, approximately 69 000 cervical cancer cases and 38 000 deaths happened in ASEAN, and more than 44% and 63% increases on new cases and deaths are expected in 2040. Only four countries have initiated population-based cervical cancer screening programs, but the participation rate is less than 50% in some countries and even lower than 10% in Myanmar and Indonesia. Inequity and unavailability in service delivery, lack of knowledge and awareness, limited follow-up and treatment capacity, and funding sustainability affect successful scale-up of cervical cancer screening most in ASEAN. Implementing HPV detection-based primary screening, appropriate management of screen-positives, enhancing health education, integrating health services can accelerate reduction of cervical cancer burden in ASEAN. Achieving high screening coverage and high treatment compliance will help ASEAN countries remain aligned to cervical cancer elimination strategies.
•Cervical cancer burden is high and rapidly increasing in ASEAN, hence need for comprehensive screening.•Four countries have initiated population-based cervical cancer screening programs but screening coverage remains low.•Service delivery, knowledge, awareness, follow-up, treatment, and funding sustainability affect scale-up of screening in ASEAN.•Implementing self-sampling, HPV test primary screening, screen-and-treat and health education, integrating health services can promote cervical cancer screening and control in ASEAN.
