ABSTRACT

Since the human papillomavirus (HPV) vaccine guidelines were developed by the Korean Society of Gynecologic Oncology (KSGO) in 2011, 2016, and 2019, several recent studies on the efficacy and safety of HPV vaccines in middle-aged women and men have been reported. Furthermore, there has been an ongoing debate regarding the efficacy of the HPV vaccine in women with prior HPV infection or who have undergone conization for cervical intraepithelial neoplasia (CIN). We searched and reviewed studies on the efficacy and safety of the HPV vaccine in middle-aged women and men and the efficacy of the HPV vaccine in patients infected with HPV and those who underwent conization for CIN. The KSGO updated their guidelines based on the results of the studies included in this review.

ABSTRACT

There have been ongoing social discussions on revision of the abortion law since the Constitutional Court ruled it nonconformity to the constitution on April 11, 2019. Thus, Korean Society of Obstetrics and Gynecology, Korean Society of Maternal Fetal Medicine, Korean College of Obstetricians and Gynecologists, and Korean Association of Obstetricians and Gynecologists organized 'special committee for abortion law' to support social discussion on the revision of the abortion law, and they prepared official opinions of obstetrics for medical issues including doctors' right to refuse abortion. In the future, the committee will continue to adapt to changes of medical environment especially after the revision of the abortion law by collecting its members' feedbacks.

ABSTRACT

In 2016, 9-valent human papillomavirus (HPV) vaccine has been newly introduced in Korea, thus the need to develop recommendations for the vaccine has raised. Until we decide to develop a guideline, no further studies on the bi-valent or quadri-valent HPV vaccine have been announced. We searched and reviewed the literatures focused on the efficacy of 9-valent HPV vaccine, the ideal age of 3-dose schedule vaccination, the efficacy of 9-valent HPV vaccine in middle-aged women, the efficacy of the 2-dose schedule vaccination, the safety of 9-valent HPV vaccine, the possibility of additional 9-valent HPV vaccination, and cross-vaccination of 9-valent HPV vaccine. So, Korean Society of Gynecologic Oncology (KSGO) developed a guideline only for 9-valent HPV vaccine.

ABSTRACT

Although cisplatin is one of the most effective antitumor drugs for ovarian cancer, the emergence of chemoresistance to cisplatin in over 80% of initially responsive patients is a major barrier to successful therapy. The precise mechanisms underlying the development of cisplatin resistance are not fully understood, but alteration of DNA methylation associated with aberrant gene silencing may play a role. To identify epigenetically regulated genes directly associated with ovarian cancer cisplatin resistance, we compared the expression and methylation profiles of cisplatin-sensitive and -resistant human ovarian cancer cell lines. We identified α-Nacetylgalactosaminidase (NAGA) as one of the key candidate genes for cisplatin drug response. Interestingly, in cisplatin-resistant cell lines, NAGA was significantly downregulated and hypermethylated at a promoter CpG site at position +251 relative to the transcriptional start site. Low NAGA expression in cisplatin-resistant cell lines was restored by treatment with a DNA demethylation agent, indicating transcriptional silencing by hyper-DNA methylation. Furthermore, overexpression of NAGA in cisplatin-resistant lines induced cytotoxicity in response to cisplatin, whereas depletion of NAGA expression increased cisplatin chemoresistance, suggesting an essential role of NAGA in sensitizing ovarian cells to cisplatin. These findings indicate that NAGA acts as a cisplatin sensitizer and its gene silencing by hypermethylation confers resistance to cisplatin in ovarian cancer. Therefore, we suggest NAGA may be a promising potential therapeutic target for improvement of sensitivity to cisplatin in ovarian cancer.

ABSTRACT

OBJECTIVES: The increase in the obesity rate in adult males in Korea is higher than countries in the Organization for Economic Co-operation and Development and other Asian countries. We examined the trends and prevalence of major risk factors for cardiovascular disease by evaluating the weight status amongst adults from 2007 to 2015. METHODS: The study included 37,402 adults, who participated in the Korea National Health and Nutrition Examination Survey. The prevalence trends of cardiovascular disease risk factors were estimated for each body mass index group. RESULTS: From 2007 to 2015, significant increases in the prevalence of hypertension, diabetes, and hypercholesterolemia were observed in normal weight adults (0.03 percentage point (%p), 0.06%p, and 0.13%p, respectively). Amongst the overweight and obese adults, a significant increase in the prevalence of hypercholesterolemia was observed, During this period, the prevalence of smoking decreased amongst obese adults and no significant changes in drinking habits and physical activity were noted across all body mass index groups. CONCLUSION: The prevalence of obesity in Korean adults is increasing, and it is necessary to implement interventions to prevent further weight gain and obesity-associated cardiovascular disease.

ABSTRACT

PURPOSE: 14-3-3ζ regulates cell signaling, cell cycle progression, and apoptosis, and its overexpression is associated with disease recurrence and poor clinical outcomes in some solid tumors. However, its clinicopathological role in ovarian cancer is unknown. Our goal was to investigate whether 14-3-3ζ is associated with ovarian cancer prognosis. MATERIALS AND METHODS: We examined 14-3-3ζ expression by immunohistochemistry in ovarian cancer tissues obtained from 88 ovarian cancer patients. The examined tissues were of various histologies and stages. 14-3-3ζ expression was also analyzed by western blot in seven ovarian cancer cell lines and a primary ovary epithelial cell line. Cell viability was measured using an MTS-based assay following cisplatin treatment. RESULTS: Among the ovarian cancer samples, 53.4% (47/88) showed high 14-3-3ζ expression, and 14-3-3ζ overexpression was positively correlated with more advanced pathologic stages and grades. 14-3-3ζ overexpression was also significantly associated with poor disease-free survival (DFS) and overall survival (OS) of ovarian cancer patients. Median DFS and OS were 1088 and 3905 days, respectively, in the high 14-3-3ζ expression group, but not reached in the low 14-3-3ζ expression group (p=0.004 and p=0.033, log-rank test, respectively). Downregulating 14-3-3ζ by RNA interference in ovarian cancer cells led to enhanced sensitivity to cisplatin-induced cell death. CONCLUSION: 14-3-3ζ overexpression might be a potential prognostic biomarker for ovarian cancer, and the inhibition of 14-3-3ζ could be a therapeutic option that enhances the antitumor activity of cisplatin.

ABSTRACT

OBJECTIVE: This prospective randomized controlled pilot study aimed to find whether gelatin-thrombin matrix used as a tissue sealant (FloSeal) can prevent the occurrence of pelvic lymphocele in patients with gynecologic cancer who has undergone pelvic lymphadenectomy. METHODS: Each patient, who undergo a laparotomic pelvic lymph node dissection on both sides, was randomly assigned for FloSeal application on 1 side of the pelvis. The other side of the pelvis without any product application being the control side. The amount of lymph drainage at each side of the pelvis was measured for 3 days, and computed tomography scans were obtained 7 days and 6 months after surgery for detection of pelvic lymphocele. RESULTS: Among 37 cases, the median amount of lymph drainage was significantly decreased in the hemi-pelvis treated with FloSeal compared to the control hemi-pelvis (p=0.025). The occurrence of lymphocele was considerably reduced in treated hemi-pelvis (8/37, 21.6%) compared with control hemi-pelvis (12/37, 32.4%) after 7 post-operative days (p=0.219), and more decreased in the treated hemi-pelvis (5/37, 13.5%) compared with control hemi-pelvis (9/37, 24.3%) after postoperative 6 months (p=0.344). CONCLUSION: The application of FloSeal as a tissue sealant in lymph nodes resected tissues can reduce the incidence of pelvic lymphocele in gynecologic cancer patients. A large randomized controlled study could confirm these preliminary results.

ABSTRACT

Clinical practice guidelines for gynecologic cancers have been developed by many organizations. Although these guidelines have much in common in terms of the practice of standard of care for uterine corpus cancer, practice guidelines that reflect the characteristics of patients and healthcare and insurance systems are needed for each country. The Korean Society of Gynecologic Oncology (KSGO) published the first edition of practice guidelines for gynecologic cancer treatment in late 2006; the second edition was released in July 2010 as an evidence-based recommendation. The Guidelines Revision Committee was established in 2015 and decided to produce the third edition of the guidelines as an advanced form based on evidence-based medicine, considering up-to-date clinical trials and abundant qualified Korean data. These guidelines cover screening, surgery, adjuvant treatment, and advanced and recurrent disease with respect to endometrial carcinoma and uterine sarcoma. The committee members and many gynecologic oncologists derived key questions from the discussion, and a number of relevant scientific literatures were reviewed in advance. Recommendations for each specific question were developed by the consensus conference, and they are summarized here, together with other details. The objective of these practice guidelines is to establish standard policies on issues in clinical areas related to the management of uterine corpus cancer based on the findings in published papers to date and the consensus of experts as a KSGO Consensus Statement.

ABSTRACT

PURPOSE: Ovarian cancer (OC) is the most fatal of gynecological malignancies with a high rate of recurrence. We aimed to evaluate the expression of solute carrier family 6, member 12 (SLC6A12) and methylation of its promoter CpG sites in a xenograft mouse model of metastatic OC, and to investigate the regulatory mechanisms that promote aggressive properties during OC progression. MATERIALS AND METHODS: Expression of SLC6A12 mRNA was determined by reverse-transcription quantitative polymerase chain reaction (RT-qPCR), and DNA methylation status of its promoter CpGs was detected by quantitative methylation-specific PCR. The metastatic potential of SLC6A12 was evaluated by in vitro migration/invasion transwell assays. Gene expression and DNA methylation of SLC6A12 and clinical outcomes were further investigated from publicly available databases from curatedOvarianData and The Cancer Genome Atlas. RESULTS: SLC6A12 expression was 8.1–14.0-fold upregulated and its DNA methylation of promoter CpG sites was 41–62% decreased in tumor metastases. After treatment with DNA methyltransferase inhibitor and/or histone deacetylase inhibitor, the expression of SLC6A12 was profoundly enhanced (~8.0-fold), strongly supporting DNA methylation-dependent epigenetic regulation of SLC6A12. Overexpression of SLC6A12 led to increased migration and invasion of ovarian carcinoma cells in vitro, approximately 2.0-fold and 3.3-fold, respectively. The meta-analysis showed that high expression of SLC6A12 was significantly associated with poor overall survival [hazard ratio (HR)=1.07, p value=0.016] and that low DNA methylation levels of SLC6A12 at specific promoter CpG site negatively affected patient survival. CONCLUSION: Our findings provide novel evidence for the biological and clinical significance of SLC6A12 as a metastasis-promoting gene.

ABSTRACT

Metastasis is a major cause of therapeutic failure in ovarian cancer. To elucidate molecular mechanisms of ovarian cancer metastasis, we previously established a metastatic xenograft mouse model using human ovarian carcinoma SK-OV-3 cells. Using gene expression profiling, we found that γ-aminobutyric acid (GABA)A receptor π subunit (GABRP) expression was upregulated (>4-fold) in metastatic tissues from our xenograft mice compared with SK-OV-3 cells. Importantly, GABRP knockdown diminished the migration and invasion of SK-OV-3 cells, and reduced extracellular signal-regulated kinase (ERK) activation while overexpression of GABRP exhibited significantly increased cell migration, invasion and ERK activation. Moreover, treatment with the mitogen-activated protein kinase (MAPK)/ERK kinase (MEK) inhibitor U0126 similarly suppressed the migration and invasion of SK-OV-3 cells, implying that GABRP promotes these cellular behaviors by activating the MAPK/ERK pathway. Using genome-wide DNA methylation profiling, we identified hypomethylated CpG sites in the GABRP promoter in metastatic tissues from the xenograft mice compared with SK-OV-3 cells. Treatment with a DNA methyltransferase inhibitor demonstrated that methylation at −963 bp from the GABRP transcription start site (−963 CpG site) was critical for the epigenetic regulation of GABRP. Finally, we analyzed human ovarian cancer patient samples and showed DNA hypomethylation at the GABRP −963 CpG site in advanced stage, but not early-stage, primary tumors compared with their paired normal tissues. These findings suggest that GABRP enhances the aggressive phenotype of ovarian cancer cells, and that the DNA methylation status of the GABRP −963 CpG site may be useful for predicting the metastatic potential in ovarian cancer patients.

ABSTRACT

PURPOSE: The purpose of this study is to evaluate the treatment outcomes of adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam radiotherapy (EBRT) following surgery for patients with stage I endometrial carcinoma. MATERIALS AND METHODS: The subjects were 43 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer who underwent adjuvant radiotherapy following surgery between March 2000 and April 2014. Of these, 25 received postoperative VB alone, while 18 received postoperative EBRT to the whole pelvis; 3 of these were treated with EBRT plus VB. The median EBRT dose was 50.0 Gy (45.0–50.4 Gy) and the VB dose was 24 Gy in 6 fractions. Tumor dose was prescribed at a depth of 5 mm from the cylinder surface and delivered twice per week. RESULTS: The median follow-up period for all patients was 57 months (range, 9 to 188 months). Five-year disease-free survival (DFS) and overall survival (OS) for all patients were 92.5% and 95.3%, respectively. Adjuvant radiotherapy was performed according to risk factors and stage IB, grade 3 and lymphovascular invasion were observed more frequently in the EBRT group. Five-year DFS for EBRT and VB alone were 88.1% and 96.0%, respectively (p = 0.42), and 5-year OS for EBRT and VB alone were 94.4% and 96%, respectively (p = 0.38). There was no locoregional recurrence in any patient. Two patients who received EBRT and 1 patient who received VB alone developed distant metastatic disease. Two patients who received EBRT had severe complications, one each of grade 3 gastrointestinal complication and pelvic bone insufficiency fracture. CONCLUSION: Adjuvant radiotherapy achieved high DFS and OS with acceptable toxicity in stage I endometrial cancer. VB (with a lower dose per fraction) may be a viable option for selected patients with early-stage endometrial cancer following surgery.

ABSTRACT

Ovarian cancer is the most lethal gynecologic cancer. Countless efforts have been made to improve the survival of ovarian cancer patients by clinicians as well as basic researchers so far. As a result of those extensive translational researches some of promising molecular targets and its proper therapies are introduced into practice for treating intractable ovarian cancer, which includes anti-angiogenic therapy, tyrosine kinase inhibitor, and other modulators of cancer-related signaling pathways. Current trend of translational researches in ovarian cancer treatment are mainly focused on discovering companion diagnostics which can categorize the subgroup of patient having specific biomarker that may serve as a target of new treatment because the consequent outcome of new therapy varies depending on the molecular profile of each patient. It is important for clinician to consider each ovarian cancer patients to have a possible therapeutic target and to examine the tissue biopsies with available companion diagnostics. In addition more interest and endeavor should be given to the clinical trials to apply the result of up-to-date translational researches.

ABSTRACT

BACKGROUND: The purpose of this study is to evaluate the outcomes of clinical education program for nurses in regional public hospital, utilizing the Kirkpatrick's model. METHODS: Kirkpatrik's 4-level model was applied to this study. Trainees were asked to fill out questionnaires in the middle and at the end of the program. Also administrators of excellent trainees were asked to fill out the questionnaires regarding nursing management performance after 1-2 months from the end of the training course. RESULTS: All trainees had positive reactions to the clinical education program. Not only the results of individual level (satisfaction and achievement scores, academic achievement scores, practical application rate, and educational transition factors) but also the scores of organization level (nursing management performance scores) are improved. CONCLUSION: By showing a correlation between the effectiveness factors we need to verify the relationship between these factors in a future study. In addition, development of quantitative and qualitative performance indicators are needed. To establish a long-term education system, it is required to applying the excellent trainee's successful experiences.

ABSTRACT

Vaginal intraepithelial neoplasia III, is a relatively rare disease. Consequently standard treatments for this disease were not established until recently. Although several convenient methods, such as laser ablation, 5-fluorouracil topical injection, and radiation therapy, have been applied for treating these lesions, surgical treatments, including vaginectomy, have not yet been attempted, as they would likely be accompanied by technical difficulties and various complications. Herein, we report a case of refractory vaginal intraepithelial neoplasia III in the vaginal vault that was successfully treated with a total vaginectomy.

ABSTRACT

After human papillomavirus (HPV) vaccine guidelines published by Korean Society of Gynecologic Oncology (KSGO) in 2011, new studies have been published, leading to additional data regarding efficacy, safety, number of vaccination rounds, and ideal age of vaccine administration. We searched and reviewed the literatures focused on the efficacy of 2-dose schedule vaccination, the efficacy of 3-dose schedule vaccination in middle-aged women, the ideal age of 3-dose schedule vaccination, the safety of HPV preventive vaccine, and the ability of cross-protection of each HPV preventive vaccine. The KSGO has revised the previous guideline based on the results of the above studies.

ABSTRACT

OBJECTIVE: Decreased adiponectin and increased leptin plasma concentrations are believed to be associated with the occurrence and progression of cancers such as endometrial cancer and breast cancer. The aim of this study was to explore the association of plasma adiponectin and leptin levels with the development and progression of ovarian cancer. METHODS: For patients with ovarian cancer and the control group, adiponectin and leptin levels were measured; anthropometric data were obtained during a chart review. Statistical comparisons between groups were analyzed using the Student's t-test; correlations were confirmed using the Pearson correlation. RESULTS: The mean adiponectin and leptin concentrations in patients with ovarian cancer were lower than those of the control group (8.25 vs. 11.44 µg/mL, respectively; P=0.026) (7.09 vs. 15.4 ng/mL, respectively; P=0.001). However, there was no significant difference in adiponectin and leptin levels between early-stage (I/II) and advanced-stage (III/IV) disease (P=0.078). CONCLUSION: Compared with other gynecological cancers, the level of adiponectin and leptin were decreased in ovarian cancer that may have some diagnostic value; additional study to elucidate the function of these two hormones in the development of ovarian carcinogenesis is necessitated.

ABSTRACT

PURPOSE: To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. MATERIALS AND METHODS: Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. RESULTS: The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. CONCLUSION: PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.
