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

Purpose@#The objective of this study was to define the learning curve required to attain satisfactory oncologic outcomes of cervical cancer patients who were undergoing open or minimally invasive surgery for radical hysterectomy, and to analyze the correlation between the learning curve and tumor size. @*Materials and Methods@#Cervical cancer patients (stage IA-IIA) who underwent open radical hysterectomy (n=280) or minimal invasive radical hysterectomy (n=282) were retrospectively reviewed. The learning curve was evaluated using cumulative sum of 5-year recurrence rates. Survival outcomes were analyzed based on the operation period (“learning period,” P1 vs. “skilled period,” P2), operation mode, and tumor size. @*Results@#The 5-year disease-free and overall survival rates between open and minimally invasive groups were 91.8% and 89.0% (p=0.098) and 96.1% and 97.2% (p=0.944), respectively. The number of surgeries for learning period was 30 and 60 in open and minimally invasive group, respectively. P2 had better 5-year disease-free survival than P1 after adjusting for risk factors (hazard ratio, 0.392; 95% confidence interval, 0.210 to 0.734; p=0.003). All patients with tumors < 2 cm had similar 5-year disease-free survival regardless of operation mode or learning curve. Minimally invasive group presented lower survival rates than open group when tumors ≥ 2 cm in P2. Preoperative conization improved disease-free survival in patients with tumors ≥ 2 cm, especially in minimally invasive group. @*Conclusion@#Minimally invasive radical hysterectomy required more cases than open group to achieve acceptable 5-year disease-free survival. When tumors ≥ 2 cm, the surgeon’s proficiency affected survival outcomes in both groups.

ABSTRACT

Objectives@#This study compared serum anti-Mullerian hormone (AMH) levels in endometriotic cysts (ECs) with those in non-ECs and analyzed changes thereof after single-port laparoscopic (SPL) ovarian cyst enucleation using vasopressin injection. @*Methods@#In total, 180 patients (EC group, n = 112; non-EC group, n = 68) who underwent SPL ovarian cyst enucleation were retrospectively reviewed. Their AMH levels were checked preoperatively, on postoperative day 10 (POD10), and on postoperative month 3 (POM3). Changes in AMH levels were analyzed according to tumor type and vasopressin use. @*Results@#The median initial and postoperative serum AMH levels in the EC group were significantly lower than those in the nonEC group (preoperation: 2.0 vs 3.8 ng/mL, P < 0.001; POD10: 1.0 vs 3.2 ng/mL, P < 0.001; POM3: 1.2 vs 3.6 ng/mL, P < 0.001). The postoperative decrease in AMH levels was higher in the EC group than the non-EC group on POD10 (0.8 vs 0.5 ng/mL, P = 0.011) but not on POM3 (0.7 vs 0.5 ng/mL, P = 0.164). Vasopressin injection during EC enucleation had no significant effect on the decrease in AMH levels on POD10 (vasopressin group vs non-vasopressin group: 1.0 vs 0.8 ng/mL, P = 0.253) and POM3 (vasopressin group vs nonvasopressin group: 1.4 vs 1.1 ng/mL, P = 0.242). @*Conclusions@#AMH levels were lower at baseline and had higher decreasing rates after SPL surgery in the EC group relative to the nonEC group. Vasopressin injection might not protect the ovary from the postoperative decrease in AMH levels.

ABSTRACT

PURPOSE: We evaluated whether adding bevacizumab to current platinum-based chemotherapy could improve clinical outcomes without affecting safety.MATERIALS AND METHODS: We retrospectively reviewed medical records of patients with pathologically confirmed ovarian cancer who received neoadjuvant chemotherapy (NAC) at Yonsei Cancer Hospital. We divided the patients into groups based on the use of bevacizumab for NAC (CP group: carboplatin+paclitaxel vs. BCP group: bevacizumab+carboplatin+paclitaxel) and compared patient characteristics, responses to NAC, and surgical and survival outcomes between the two groups. Overall, 88 patients in the CP group and 16 patients in the BCP group received NAC. The primary endpoint was survival outcomes. Complete resection rate after interval debulking surgery (IDS), cancer antigen 125 (CA-125) normalization after NAC, and chemotherapy response score were secondary endpoints.RESULTS: After NAC treatment, all patients underwent IDS. There were no significant differences in adverse events during NAC or postoperative complications between the two groups (p=0.293 and p=0.485, respectively). There were also no significant differences in CA-125 normalization after NAC (42.0% vs. 43.8%, p=0.899) or complete resection rate after IDS (47.7% vs. 56.3%, p=0.530). However, although the BCP group did not show longer overall survival (OS) (log-rank p=0.854), they had significantly longer progression-free survival (PFS) than the CP group (log-rank p=0.048).CONCLUSION: Bevacizumab-containing NAC might be safe and provide longer PFS than chemotherapy alone in patients with advanced ovarian cancer. However, further study is necessary to investigate the impact of bevacizumab-containing NAC on OS.

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness and safety of the combination of pegylated liposomal doxorubicin with carboplatin (CD) compared with those of carboplatin and paclitaxel (CP) for platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer in a real-world setting in Korea.@*METHODS@#We enrolled relevant patients from 9 institutions. All patients received CD or CP as the second- or third-line chemotherapy in routine clinical practice during 2013–2018. The primary endpoints were progression-free survival (PFS) and toxicity. The secondary endpoint included the objective response rate (ORR).@*RESULTS@#Overall, 432 patients (224 and 208 in the CD and CP groups, respectively) were included. With a median follow-up of 18.9 months, the median PFS was not different between the groups (12.7 vs. 13.6 months; hazard ratio, 1.161; 95% confidence interval, 0.923–1.460; p=0.202). The ORR was 74.6% and 80.1% in the CD and CP group, respectively (p=0.556). Age and surgery at relapse were independent prognostic factors. More patients in the CD group significantly experienced a grade 3 to 4 hematologic toxicity and hand-foot syndrome (13.8% vs. 6.3%), whereas grade 2 or more alopecia (6.2% vs. 36.1%), peripheral neuropathy (4.4% vs. 11.4%), and allergic/hypersensitivity reaction (0.4% vs. 8.5%) developed more often in the CP group.@*CONCLUSIONS@#The safety and effectiveness of chemotherapy with CD in a real-world setting were consistent with the results from a randomized controlled study. The different toxicity profiles between the 2 chemotherapy (CD and CP) regimens should be considered in the clinical practice.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03562533

ABSTRACT

OBJECTIVE@#To compare the efficacy and toxicity of dose-dense weekly paclitaxel and 3-weekly carboplatin (ddPC) as neoadjuvant chemotherapy (NAC) with the standard 3-weekly regimen.@*METHODS@#A retrospective study of patients diagnosed with stage IIIc and IV ovarian cancer who received at least one cycle of NAC followed by interval debulking surgery between August 2015 and January 2018 was conducted. Patient characteristics, clinical and pathological response to NAC, surgical and survival outcome, and adverse event were compared.@*RESULTS@#A total of 23 patients in the ddPC group and 50 patients in the standard group received a median of 3 cycles of NAC. Rate of grade ≥3 neutropenia was significantly higher in the ddPC group than the standard (82.6% vs. 22.0%, p<0.001). Patients in the ddPC group underwent dose-reduction more frequently (34.8% vs. 4.00%, p=0.001). Normalization of cancer antigen-125 post-NAC occurred more frequently in the ddPC group (73.9% vs. 46.0%, p=0.030). No residual disease rate (43.5% vs. 60.0%, p=0.188) and chemotherapy response score of 3 (34.8% vs. 26.0%, p=0.441) were not statistically different between two groups. There was no statistical difference in progression free survival (PFS) at 2 years (36.3% vs. 28.4%, p=0.454). Cox proportional hazard model showed that ddPC was not a significant determinant of PFS (p=0.816).@*CONCLUSION@#There was no difference between both regimens in terms of NAC response and survival outcomes. However, ddPC group showed higher hematologic toxicity requiring dose reduction.

ABSTRACT

Malakoplakia is a rare granulomatous, inflammatory disease generally manifesting as ulcers of the urogenital tract, especially in the bladder, but it can occur in any part of the body. Because of its varied clinical presentations, malakoplakia is considered for differential diagnosis upon suspicion. The final diagnosis is confirmed by the presence of Michaelis-Gutmann bodies. We report a case of pelvic malakoplakia accompanied by left lower quadrant pain that was misdiagnosed as endometrial cancer with pelvic mass based on imaging studies. The patient underwent dilatation and curettage, and the pathology report revealed no malignancy. Because of persistent pain and septic shock, she underwent a debulking operation to remove the mass. Histopathologic examination revealed malakoplakia. For postoperative management, she received broad-spectrum antibiotics, but abdominal pelvic computerized tomography performed on postoperative day 9 revealed pelvic mass recurrence. To the best of our knowledge, this is the only rare case report of pelvic malakoplakia mimicking endometrial cancer.

ABSTRACT

Purpose@#The aim of this study was to evaluate the ability of sequential 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) after one cycle of neoadjuvant chemotherapy (NAC) to predict chemotherapy response before interval debulking surgery (IDS) in advanced-stage ovarian cancer patients. @*Materials and Methods@#Forty consecutive patients underwent 18F-FDG-PET/CT at baseline and after one cycle of NAC. Metabolic responses were assessed by quantitative decrease in the maximum standardized uptake value (SUVmax) with PET/CT. Decreases in SUVmax were compared with cancer antigen 125 (CA-125) level before IDS, response rate by Response Evaluation Criteria in Solid Tumors criteria before IDS, residual tumor at IDS, and I chemotherapy response score (CRS) at IDS. @*Results@#A 40% cut-off for the decrease in SUVmax provided the best performance to predict CRS 3 (compete or near-complete pathologic response), with sensitivity, specificity, and accuracy of 81.8%, 72.4%, and 72.4%, respectively. According to this 40% cut-off, there were 17 (42.5%) metabolic responders (≥ 40%) and 23 (57.5%) metabolic non-responders (< 40%). Metabolic responders had higher rate of CRS 3 (52.9% vs. 8.7%, p=0.003), CA-125 normalization (< 35 U/mL) before IDS (76.5% vs. 39.1%, p=0.019), and no residual tumor at IDS (70.6% vs. 31.8%, p=0.025) compared with metabolic non-responders. There were significant associations with progression-free survival (p=0.021) between metabolic responders and non-responders, but not overall survival (p=0.335). @*Conclusion@#Early assessment with 18F-FDG-PET/CT after one cycle of NAC can be useful to predic response to chemotherapy before IDS in patients with advanced-stage ovarian cancer.

ABSTRACT

BACKGROUND: A single-arm phase II study of neoadjuvant chemotherapy plus durvalumab and tremelimumab in the treatment of advanced-stage ovarian cancer has begun in Korea. We hypothesized that adding durvalumab (anti-programmed death-ligand 1 antibody) and tremelimumab (anti-cytotoxic T-lymphocyte-associated protein 4 antibody) to chemotherapy in treating this cancer can increase progression-free survival (PFS) with minimal effects on safety. METHODS: During treatment, serial biopsies will be performed on pre-treatment, at interval debulking surgery and progression to identify immune biomarkers and changes in the tumor microenvironment. Patients with histologically confirmed stage IIIC/IV epithelial ovarian cancer are offered durvalumab, tremelimumab plus chemotherapy for neoadjuvant chemotherapy and durvalumab plus chemotherapy for adjuvant chemotherapy. Twenty-four patients will be included from four Korean institutions within 1 year. The primary endpoint is a 12-month PFS rate. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03899610

ABSTRACT

On the basis of emerging data and the current understanding of minimally invasive surgery (MIS) for radical hysterectomy (RH) in women with cervical cancer, the Korean Society of Gynecologic Oncology, Korean Society of Obstetrics and Gynecology, and Korean Society of Gynecologic Endoscopy and Minimally Invasive Surgery support the following recommendations: • According to the recently published phase III Laparoscopic Approach to Cervical Cancer (LACC) trial—a prospective randomized clinical trial—disease-free survival and overall survival rates of MIS RH are significantly lower than those of open RH. • Gynecologic oncologists should be aware of the emerging data on MIS RH for early-stage cervical cancer. • The results of the LACC trial, together with institutional data, should be discussed with patients before choosing MIS RH. • MIS RH should be performed for optimal candidates according to the current practice guidelines by gynecologic oncologists who are skilled at performing MIS.

ABSTRACT

PURPOSE: Recurrence and chemoresistance (CR) are the leading causes of death in patients with high-grade serous carcinoma (HGSC) of the ovary. The aim of this study was to identify genetic changes associated with CR mechanisms using a patient-derived xenograft (PDX) mouse model and genetic sequencing. MATERIALS AND METHODS: To generate a CR HGSC PDX tumor, mice bearing subcutaneously implanted HGSC PDX tumors were treated with paclitaxel and carboplatin. We compared gene expression and mutations between chemosensitive (CS) and CR PDX tumors with whole exome and RNA sequencing and selected candidate genes. Correlations between candidate gene expression and clinicopathological variables were explored using the Cancer Genome Atlas (TCGA) database and the Human Protein Atlas (THPA). RESULTS: Three CR and four CS HGSC PDX tumor models were successfully established. RNA sequencing analysis of the PDX tumors revealed that 146 genes were significantly up-regulated and 54 genes down-regulated in the CR group compared with the CS group. Whole exome sequencing analysis showed 39 mutation sites were identified which only occurred in CR group. Differential expression of SAP25,HLA-DPA1, AKT3, and PIK3R5 genes and mutation of TMEM205 and POLR2A may have important functions in the progression of ovarian cancer chemoresistance. According to TCGA data analysis, patients with high HLA-DPA1 expression were more resistant to initial chemotherapy (p=0.030; odds ratio, 1.845). CONCLUSION: We successfully established CR ovarian cancer PDX mouse models. PDX-based genetic profiling study could be used to select some candidate genes that could be targeted to overcome chemoresistance of ovarian cancer.

ABSTRACT

PURPOSE: Identification of lymph node (LN) metastasis in non-small cell lung cancer (NSCLC) is critical for disease staging and selection of therapeutic modalities. Sometimes it is not possible to obtain LN core tissue by endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA), resulting in low diagnostic yield. MATERIALS AND METHODS: In this study, 138 specimens were collected from 108 patients who underwent EBUS-TBNA under the suspicion of LN metastasis of NSCLC. Diagnostic yields of anti-CD45 and anti-methionyl-tRNA synthetase (MRS), immunofluorescent (IF) staining on cytology specimens were compared with those of conventional cytology and positron emission tomography-computed tomography (PET-CT). RESULTS: MRS was strongly expressed in NSCLC cells metastasized to LNs, but weakly expressed in cells at the periphery of the LN germinal center. The majority of cells were CD20 positive, although a few cells were either CD3 or CD14 positive, indicating that CD45 staining is required for discrimination of non-malignant LN constituent cells from NSCLC cells. When the diagnostic efficacy of MRS/CD45 IF staining was evaluated using 138 LN cellular aspirates from 108 patients through EBUS-TBNA, the sensitivity was 76.7% and specificity was 90.8%, whereas those of conventional cytology test were 71.8% and 100.0%, respectively. Combining the results of conventional cytology testing and those of PET-CT showed a sensitivity and specificity of 71.6% and 100%, and the addition of MRS/CD45 dual IF data to this combination increased sensitivity and specificity to 85.1% and 97.8%, respectively. CONCLUSION: MRS/CD45 dual IF staining showed good diagnostic performance and may be a good tool complementing conventional cytology test for determining LN metastasis of NSCLC.

ABSTRACT

PURPOSE: Few efforts have been made to integrate a next generation sequencing (NGS) panel into standard clinical treatment of ovarian cancer. The aim of this study was to investigate the clinical utility of NGS and to identify clinically impactful information beyond targetable alterations. MATERIALS AND METHODS: We conducted a retrospective review of 84 patients with ovarian cancer who underwent NGS between March 1, 2017, and July 31, 2018, at the Yonsei Cancer Hospital. We extracted DNA from formalin-fixed, paraffin-embedded tissue samples of ovarian cancer. The TruSight Tumor 170 gene panel was used to prepare libraries, and the MiSeq instrument was used for NGS. RESULTS: Of the 84 patients, 55 (65.1%) had high-grade serous carcinomas. Seventy-three (86.7%) patients underwent NGS at the time of diagnosis, and 11 (13.3%) underwent NGS upon relapse. The most common genetic alterations were in TP53 (64%), PIK3CA (15%), and BRCA1/2 (13%), arising as single nucleotide variants and indels. MYC amplification (27%) was the most common copy number variation and fusion. Fifty-seven (67.9%) patients had more than one actionable alteration other than TP53. Seven (8.3%) cases received matched-target therapy based on the following sequencing results: BRCA1 or 2 mutation, poly ADP ribose polymerase inhibitor (n=5); PIK3CA mutation, AKT inhibitor (n=1); and MLH1 mutation, PD-1 inhibitor (n=1). Fifty-three (63.0%) patients had a possibility of treatment change, and 8 (9.5%) patients received genetic counseling. CONCLUSION: Implementation of NGS may help in identifying patients who might benefit from targeted treatment therapies and genetic counseling.

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

OBJECTIVE: To evaluate the efficacy of combined oral medroxyprogesterone acetate (MPA)/levonorgestrel-intrauterine system (LNG-IUS) treatment and to compare the diagnostic accuracy of endometrial aspiration biopsy with dilatation & curettage (D&C) in young women with early-stage endometrial cancer (EC) who wished to preserve their fertility. METHODS: A prospective phase II multicenter study was conducted from January 2012 to January 2017. Patients with grade 1 endometrioid adenocarcinoma confined to the endometrium were treated with combined oral MPA (500 mg/day)/LNG-IUS. At 3 and 6 months of treatment, the histologic change of the endometrial tissue was assessed. The regression rate at 6 months treatment and the consistency of the histologic results between the aspiration biopsy and the D&C were evaluated. RESULTS: Forty-four patients were enrolled. Nine voluntarily withdrew and 35 patients completed the protocol treatment. The complete regression (CR) rate at 6 months was 37.1% (13/35). Partial response was shown in 25.7% of cases (9/35). There were no cases of progressive disease and no treatment-related complications. A comparison of the pathologic results from aspiration biopsy and D&C was carried out for 33 cases. Fifteen cases were diagnosed as “EC” by D&C. Among these, only 8 were diagnosed with EC from aspiration biopsy, yielding a diagnostic concordance of 53.3% (ĸ=0.55). CONCLUSION: Combined oral MPA/LNG-IUS treatment for EC showed 37.1% of CR rate at 6 months. Considering the short treatment periods, CR rate may be much higher if the treatment continued to 9 or 12 months. So, this treatment is still a viable treatment option for young women of early-stage EC. Endometrial aspiration biopsy with the LNG-IUS in place is less accurate than D&C for follow-up evaluation of patients undergoing this treatment.

ABSTRACT

OBJECTIVES: We conducted a protocol-based cohort study to evaluate the outcomes of interval debulking surgery (IDS) followed by paclitaxel-based hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of advanced-stage ovarian cancer. METHODS: From October 2015 to May 2018, 65 patients with stages IIIC–IV ovarian cancer were treated according to the study protocol. HIPEC was performed with paclitaxel (175 mg/m2) for 90 minutes, only in cases of optimal cytoreduction. RESULTS: Of 65 patients, 40 (61.5%) patients underwent neoadjuvant chemotherapy (NAC), 34 (52.3%) patients had a high tumor burden with a Fagotti score ≥8 at diagnostic laparoscopy, and 6 (9.2%) had definite stage IV metastasis and/or poor performance status before NAC. Twenty-seven (41.5%) patients underwent IDS followed by HIPEC. The mean duration of IDS with HIPEC was 543.8 (range, 277.0–915.0) minutes. Grade III/IV perioperative complications occurred in 7.4% (n=2)/3.7% (n=1) of patients and no cases of mortality were reported within 30 days postoperatively. The median progression-free survival was 21.3 months, and the median overall survival was not reached for those who received HIPEC. CONCLUSIONS: According to our study protocol, IDS followed by paclitaxel-based HIPEC as a first-line treatment appears to be feasible and safe for the treatment of advanced-stage ovarian cancer. Further evaluations of this procedure are required to assess its survival benefits.
