1.  Impact of body mass index on the prognosis of Korean women with endometrioid adenocarcinoma of the uterus: A cohort study 
Obstetrics & Gynecology Science  2014;57(2):115-120.
Objective
To analyze how pretreatment body mass index relates to known endometrial cancer prognostic factors and how it impacts the disease-free survival and cause-specific survival of Korean women with endometrial cancer.
Methods
The patients were divided into the non-obese (<25 kg/m2) and obese groups (≥25 kg/m2) according to their pretreatment body mass index. The 25 kg/m2 body mass index cut-off was based on the World Health Organization criteria for Asian people. The two groups were compared in terms of their clinicopathological characteristics and survival outcomes.
Results
A total of 213 consecutive patients with endometrioid adenocarcinoma of the uterus met the eligibility criteria of this study and were included in the analysis. Of these patients, 105 patients had a body mass index less than 25 kg/m2 (non-obese group) and 108 patients had a body mass index equal to or more than 25 kg/m2 (obese group). The two groups did not differ in terms of age, menopause, parity, height, FIGO (International Federation of Obstetrics and Gynecology) stage, tumor grade, tumor size, myometrial invasion, lymphovascular space invasion, cytology, and lymph node metastasis. Body mass index was not a significant factor for disease-free and cause-specific survival in univariate analysis, and after adjusting for all prognostic factors that were significant in univariate analysis, it did not associate significantly with disease-free and cause-specific survival.
Conclusion
In Korean women with endometrioid adenocarcinoma of the uterus, a high pretreatment body mass index did not associate with other prognostic factors and had little impact on the disease-free survival and cause-specific survival of these women.

2.  Reproductive outcomes after laparoscopic radical trachelectomy for early-stage cervical cancer 
Objective
The objective of this study was to estimate the reproductive outcome of young women with early-stage cervical cancer who underwent fertility-sparing laparoscopic radical trachelectomy (LRT).
Methods
We performed a retrospective review of the medical records of patients with early-stage cervical cancer who underwent LRT. Clinicopathological data were obtained from patient medical records, and reproductive outcome data were obtained from patient medical records and telephone interviews.
Results
Fifty-five patients who underwent successful LRT were included in this study. The median age of patients was 32 years (range, 22 to 40 years), and the median follow-up time after LRT was 37 months (range, 3 to 105 months). Menstruation resumed in all patients after LRT, with fifty patients (90.9%) and five patients (9.1%) reporting regular and irregular menstruation, respectively. Six patients (10.9%) presented with cervical stenosis, which was manifested by regular but decreased menstrual flow and newly-developed dysmenorrhea. These patients underwent cervical cannulation and dilatation. Eighteen patients (32.7%) attempted to conceive, with six out of 18 patients receiving fertility treatments. Fourteen pregnancies (i.e., four missed abortions, six preterm births and four full-term births) occurred in 10 patients after LRT. Nine out of 10 patients gave birth to 10 healthy babies. The pregnancy rate after LRT was 55.6% (10/18). The spontaneous abortion rate and live birth rate were 28.6% (4/14) and 71.4% (10/14), respectively. The preterm birth rate was 60% (6/10).
Conclusion
Pregnancy and live birth rates after LRT were promising; however, the preterm birth rate was relatively high. Cervical stenosis also occurred in a small percentage of patients.

3.  Combination therapy of renal cell carcinoma or breast cancer patients with dendritic cell vaccine and IL-2: results from a phase I/II trial 
Background
Ten cancer patients (Six renal cell carcinoma and four breast cancer patients) were treated in a phase I/II study with a vaccine composed of autologous dendritic cells (DCs) and IL-2 to evaluate the DC vaccine-related toxicity and antigen-specific immune alteration.
Methods
Cancer patients were treated twice with autologous CD34+ hematopoietic stem cell-derived, GM-CSF/IFN-γ-differentiated DCs pulsed with autologous tumor lysate and KLH, by 4-week interval. Following each subcutaneous injection of therapeutic DCs, low-dose (200 MIU) IL-2 was introduced for 14 consecutive days as an immune adjuvant. To determine the DC vaccine-induced immunological alterations, the KLH-specific lymphocyte proliferation, number of IFN-γ secreting T cells (ELISPOT assay), NK activity and the cytokine modulation were measured.
Results
Cultured-DCs expressing HLA-DR, CD11c, CD83, and B7.1/B7.2 produced IL-12p70. After vaccination, the patients tolerated it. Clinical response was observed in one RCC patient as stable disease. However DC-vaccine related antigen-specific immune responses including peripheral blood lymphocyte proliferation and the number of IFN-r secreting cells were induced in six patients without clear correlation with clinical responses. Also NK activity was induced significantly in six patients after vaccination. DC vaccine-related decrease of TGF-β level or increase of IL-12p70 level and decline of CD4+CD25+ T cells were observed in three patients. However only in the RCC patient whose disease stabilized, combination of stimulatory as well as inhibitory immune alterations including induction of IFN-γ secreting T cell with reduction of CD4+ CD25+ T cell were correlated with clinical responses.
Conclusion
Data indicated that DC vaccine combined with IL-2 is well tolerated without major side effects. DC vaccine induced the specific immunity against introduced antigen. Combinatorial alterations of immunological parameters indicating antigen-specific immune induction along with reduction of inhibitory immunity were correlated with clinical responses in DC vaccine treated patients.

5.  Proliferation of CD4+CD25high+Foxp3+ regulatory T lymphocytes in ex vivo expanded ascitic fluid from primary and recurrent ovarian carcinoma 
Objective
Regulatory T lymphocytes evoke the immune tolerance by suppressing and inactivating cytotoxic T lymphocytes. The objective of this study was to compare the proportion of regulatory T lymphocytes, precisely defined as CD4+CD25high+Foxp3+ T lymphocytes, in primary and recurrent ovarian carcinoma before and after ex vivo expansion of ascites with interleukin-2 (IL-2).
Methods
Ascitic fluid samples were obtained from 26 patients with ovarian carcinoma. Lymphocytes were isolated from ascites and cell markers were analyzed by flow cytometry using anti-CD3/CD4/CD8/CD16/CD56/CD25 and anti-Foxp3 antibodies. Lymphocytes were incubated for 2 to 3 weeks and expanded ex vivo by IL-2 stimulation and their phenotypes were analyzed by flow cytometry.
Results
Following ex vivo expansion, ascitic fluid lymphocytes increased by a greater extent in the recurrent group than in the primary group. The proportion of ex vivo-expanded lymphocytes changed as follows; CD4+ T lymphocytes increased, CD8+ T lymphocytes decreased, and the proportion of CD3-CD16+56+ NK cells was unchanged. The proportion of CD4+CD25high+Foxp3+ regulatory T lymphocytes in CD4+ T lymphocytes increased after ex vivo expansion in both groups, but to a greater degree in the recurrent group.
Conclusion
This study showed that regulatory T lymphocytes, neither cytotoxic T lymphocytes nor NK cells, were extensively increased after ex vivo expansion, especially in recurrent ovarian carcinoma. These results may provide information that helps to guide the future development of adoptive immunotherapy against ovarian carcinoma.

6.  Pure Basaloid Squamous Cell Carcinoma of the Uterine Cervix: A Case Report 
Journal of Korean Medical Science  2009;24(3):542-545.
Basaloid squamous cell carcinoma of the uterine cervix is an extremely rare malignancy of the female genital tract with a poorer clinical outcome than squamous cell carcinoma of the uterine cervix. We report a case of pure basaloid squamous cell carcinoma of the uterine cervix. A 70-yr-old woman with vaginal bleeding was referred to our institute. A basaloid squamous cell carcinoma of the uterine cervix, of International Federation of Gynecology and Obstetrics (FIGO) stage Ib1, was diagnosed by a loop electrosurgical excision procedure cone biopsy. A radical hysterectomy was performed, along with bilateral salpingo-oophorectomy, pelvic lymph node dissection, and para-aortic lymph node sampling. Pathologic findings were consistent with a basaloid squamous cell carcinoma confined to the cervix without an extracervical tumor. No further treatment was administered and there was no clinical evidence of recurrence during the 12 months of follow-up. Follow-up for the patient is ongoing. Although basaloid squamous cell carcinoma of the uterine cervix is thought to behave aggressively, accumulation of data on these rare tumors is necessary to determine whether their behavior differs significantly from that of conventional cervical squamous cell carcinoma of similar clinical stage. These data would be useful for defining the best diagnosis and treatment for these rare tumors.

7.  Cost–utility analysis for platinum-sensitive recurrent ovarian cancer therapy in South Korea: results of the polyethylene glycolated liposomal doxorubicin/carboplatin sequencing model 
Objective
We performed a cost–utility analysis to assess the cost-effectiveness of a chemotherapy sequence including a combination of polyethylene glycolated liposomal doxorubicin (PLD)/carboplatin versus paclitaxel/carboplatin as a second-line treatment in women with platinum-sensitive ovarian cancer.
Methods
A Markov model was constructed with a 10-year time horizon. The treatment sequence consisted of first- to sixth-line chemotherapies and best supportive care (BSC) before death. Cycle length, a time interval for efficacy evaluation of chemotherapy, was 9 weeks. The model consisted of four health states: responsive, progressive, clinical remission, and death. At any given time, a patient may have remained on a current therapy or made a transition to the next therapy or death. Median time to progressions and overall survivals data were obtained through a systematic literature review and were pooled using a meta-analytical approach. If unavailable, this was elicited from an expert panel (eg, BSC). These outcomes were converted to transition probabilities using an appropriate formula. Direct costs included drug-acquisition costs for chemotherapies, premedication, adverse-event treatment and monitoring, efficacy evaluation, BSC, drug administration, and follow-up tests during remission. Indirect costs were transportation expenses. Utilities were also derived from the literature. Costs and utilities were discounted at an annual rate of 5% per cycle.
Results
PLD/carboplatin combination as the second line in the sequence is more effective and costly than paclitaxel/carboplatin combination, showing an additional US$21,658 per quality-adjusted life years. This result was robust in a deterministic sensitivity analysis except when median time to progression of second-line therapies and administration cost of PLD/carboplatin per administration cycle were varied. The probability of cost-effectiveness for PLD/carboplatin combination was 49.4% at a willingness to pay $20,000.
Conclusion
A PLD/carboplatin combination is an economically valuable option as second-line chemotherapy for the treatment of platinum-sensitive ovarian cancer in South Korea.

8.  Cytological Evaluation and REBA HPV-ID HPV Testing of Newly Developed Liquid-Based Cytology, EASYPREP: Comparison with SurePath 
Korean Journal of Pathology  2013;47(3):265-274.
Background
The objective of this study was to evaluate a newly-developed EASYPREP liquid-based cytology method in cervicovaginal specimens and compare it with SurePath.
Methods
Cervicovaginal specimens were prospectively collected from 1,000 patients with EASYPREP and SurePath. The specimens were first collected by brushing for SurePath and second for EASYPREP. The specimens of both methods were diagnosed according to the Bethesda System. Additionally, we performed to REBA HPV-ID genotyping and sequencing analysis for human papillomavirus (HPV) on 249 specimens.
Results
EASYPREP and SurePath showed even distribution of cells and were equal in cellularity and staining quality. The diagnostic agreement between the two methods was 96.5%. Based on the standard of SurePath, the sensitivity, specificity, positive predictive value, and negative predictive value of EASYPREP were 90.7%, 99.2%, 94.8%, and 98.5%, respectively. The positivity of REBA HPV-ID was 49.4% and 95.1% in normal and abnormal cytological samples, respectively. The result of REBA HPV-ID had high concordance with sequencing analysis.
Conclusions
EASYPREP provided comparable results to SurePath in the diagnosis and staining quality of cytology examinations and in HPV testing with REBA HPV-ID. EASYPREP could be another LBC method choice for the cervicovaginal specimens. Additionally, REBA HPV-ID may be a useful method for HPV genotyping.

9.  Comparison of outcomes between radical hysterectomy followed by tailored adjuvant therapy versus primary chemoradiation therapy in IB2 and IIA2 cervical cancer 
Journal of Gynecologic Oncology  2012;23(4):226-234.
Objective
To compare survival outcomes and treatment-related morbidities between radical hysterectomy (RH) and primary chemoradiation therapy (CRT) in patients with bulky early-stage cervical cancer.
Methods
We selected 215 patients with stage IB2 and IIA2 cervical cancer (tumor diameter > 4 cm on magnetic resonance imaging) who underwent RH followed by tailored adjuvant therapy (n=147) or primary CRT (n=68) at two tertiary referral centers between 2001 and 2010.
Results
About twenty nine percent of patients were cured by RH alone and these patients experienced the best survival outcomes with the lowest morbidity rates. After the median follow-up times of 40 months, 27 RH (18.4%) and 20 CRT (29.4%) patients had recurrence (p=0.068) and 23 (15.6%) and 17 (25%) patients died of disease (p=0.101). The 5-year progression-free survival were 77% and 66% (p=0.047), and the 5-year overall survival were 78% and 67% (p=0.048) after RH and primary CRT, respectively. In multivariate analysis, patients who received primary CRT was at higher risk for tumor recurrence (odds ratio [OR], 2.26; 95% confidence interval [CI], 1.24 to 4.14; p=0.008) and death (OR, 3.02; 95% CI, 1.53 to 5.98; p=0.001) than those who received RH. Grade 3-4, early (17% vs. 30.9%, p=0.021) and late (1.4% vs. 8.8%, p=0.007) complications were significantly less frequent after RH than primary CRT.
Conclusion
Thirty percent of patients were cured by RH alone. A treatment outcome was better in this retrospective study in terms of morbidity and survival. Randomized trials are needed to confirm this result.

10.  Proteasome Inhibition Induces α-Synuclein SUMOylation and Aggregate Formation 
Journal of the neurological sciences  2011;307(1-2):157-161.
Parkinson's disease (PD) and Dementia with Lewy bodies (DLB) are characterized pathologically by intraneuronal inclusions called Lewy bodies (LBs) and Lewy neurites. A major component of these inclusions is the protein α-synuclein, which is natively unfolded but forms oligomers and insoluble fibrillar aggregates under pathological conditions. Although α-synuclein is known to undergo several posttranslational modifications, the contribution of SUMOylation to α-synuclein aggregation and the pathogenesis of α-synucleinopathies have not been elucidated. Here, we provide evidence that aggregates and inclusions formed as a result of impaired proteasome activity contain SUMOylated α-synuclein. Additionally, SUMO1 is present in the halo of LBs colocalizing with α-synuclein in the brains of PD and DLB patients. Interestingly, SUMOylation does not affect the ubiquitination of α-synuclein. These findings suggest that proteasomal dysfunction results in the accumulation of SUMOylated α-synuclein and subsequently its aggregation, pointing to the contribution of this posttranslational modification to the pathogenesis of inclusion formation in α-synucleinopathies.

11.  Epidemiological characteristics of ovarian cancer in Korea 
Journal of Gynecologic Oncology  2010;21(4):241-247.
Objective
This study was conducted to examine recent trends in ovarian cancer incidence and mortality and secular trends in demographic factors in Korea.
Methods
With the data from Korea Central Cancer Registry, International Agency for Research on Cancer, Korean Death Registry, and World Health Organization's Statistical Information System, we calculated age-standardized incidence and mortality rates for ovarian cancer. Also we estimated future incidence of ovarian and cervical cancer using linear regression model. To assess the demographic trend, data from national surveys in Korea or results from published papers were searched.
Results
Ovarian cancer incidence rate was similar to that in women worldwide but lower than those in Western countries, and the trend has been increased steadily. Ovarian cancer-related mortality rates have been increasing in Korea, even though those in western and some Asian countries, such as China, have been decreasing. Age-specific incidence rate and mortality rate showed steep increases with advancing age. The incidence rate of ovarian cancer was estimated to surpass that of uterine cervix cancer in 2015. Korea showed rapid changes in nutritional, reproductive, and anthropometric factors.
Conclusion
These recent trends in ovarian cancer incidence and mortality may be partly attributed to gradual westernizing of life styles and to changes in socio-demographic behavior factors. In particular, the increasing trend in ovarian cancer mortality in Korea may be attributed to a real rise in mortality as well as, in part, a decline in misclassification bias related to an increase in the proportion of deaths confirmed by physician diagnosis.

12.  Hexamethylmelamine as Consolidation Treatment for Patients with Advanced Epithelial Ovarian Cancer in Complete Response after First-Line Chemotherapy 
Journal of Korean Medical Science  2009;24(4):679-683.
The aim of this study was to assess the efficacy of consolidation therapy with hexamethylmelamine (HMM) in patients with advanced epithelial ovarian cancer (EOC). Patients treated at our hospital between January 1997 and November 2006 and in documented clinical complete response from advanced ovarian cancer following front-line platinum-based therapy were retrospectively analyzed. The patients treated with HMM were compared to the patients of matched counterpart without consolidation therapy. Of 102 patients enrolled, 49 were treated with HMM and 53 received no consolidation treatment. For patients with HMM and observed patients, the mean age were 54.6 and 55.6 yr; the distribution of stage was similar (P=0.977); the optimal surgery was performed in 36 (73.5%) and 44 (83%) (P=0.336); the recurrence rate were 27 (55.1%) and 33 (62.3%) (P=0.463); and the median progression-free survival were 38 months and 21 months for patients with HMM and observed patients (P=0.235). No treatment-related adverse events were reported during the follow-up period. Although this study failed to show the significant survival benefit of consolidation therapy with HMM in patients with advanced EOC, we consider that our study can contribute data to investigate the effectiveness of consolidation therapy in epithelial ovarian cancer.

13.  Efficacy of taxane and platinum-based chemotherapy guided by extreme drug resistance assay in patients with epithelial ovarian cancer 
Journal of Gynecologic Oncology  2009;20(2):96-100.
Objective
To evaluate the efficacy of taxane and platinum-based chemotherapy guided by extreme drug resistance assay (EDRA) in patients with epithelial ovarian cancer.
Methods
Thirty-nine patients were enrolled, who were diagnosed as epithelial ovarian cancer, tubal cancer or primary peritoneal carcinoma and received both debulking surgery and EDRA in Asan Medical Center between August 2004 and August 2006. Another thirty-nine patients were enrolled, who did not receive EDRA as control. Paclitaxel 175 mg/m2 and carboplatin AUC 5 were administered as primary combination chemotherapy to both EDRA group and the control group. In the EDRA group, paclitaxel was replaced by docetaxel 75 mg/m2 if a patient showed extreme drug resistance (EDR) to paclitaxel and not to docetaxel. Carboplatin was replaced by cisplatin 75 mg/m2 if a patient showed EDR to carboplatin and not to cisplatin. If only one drug showed low drug resistance (LDR), it was allowed to add another drug which showed LDR such as gemcitabine 1,000 mg/m2. CT scan was performed every three cycles and CA-125 was checked at each cycle.
Results
There was no significant difference in overall response rate between EDRA group and the control group (84.5% vs. 71.8%, p=0.107). However, 93.8% of patients in EDRA group did not show EDR to at least one drug and its response rate was significantly higher than that of the control group (93.3% vs. 71.8%, p=0.023).
Conclusion
we could choose a combination of taxane and platinum which did not show EDR and could obtain a good response in the patients with ovarian cancer.

14.  Mutational Analysis of KRAS, BRAF, and TP53 Genes of Ovarian Serous Carcinomas in Korean Women 
Yonsei Medical Journal  2009;50(2):266-272.
Purpose
To assess the prevalence of KRAS, BRAF, and TP53 mutations in cases of low-grade and high-grade serous carcinomas and to evaluate the clinical outcomes of these morphologically distinct carcinomas.
Materials and Methods
Patients with primary invasive serous carcinomas were classified according to the universal grading system. Grade 2 serous tumors were excluded. A total of 100 patients were included for clinical evaluation. Thirty-seven patients, including 20 with low-grade and 17 with high-grade carcinomas, were selected for mutational analysis.
Results
The low-grade carcinoma group was characterized by young age and premenopausal period compared with the high-grade carcinoma group, but there were no statistically significant differences in stage, metastasis of lymph node and residual disease. There were no statistically significant differences in survival rates, however, the low-grade carcinoma group showed a trend for improved progression-free survival compared with the high-grade carcinoma group of early stage (p = 0.064). Mutations in KRAS and BRAF were found in 6 (30%) and 2 (10%) patients in the low-grade carcinoma group, respectively, however, they were not found in the high-grade carcinoma group. KRAS and BRAF mutations were mutually exclusive, and both mutations were observed in 40% (8/20). The frequency of TP53 mutations in low-grade and high-grade carcinoma groups were found in 20% (4/20) and 70.6% (12/17), respectively (p = 0.009).
Conclusion
Low-grade serous carcinoma shows mutation pattern different from that with high-grade carcinoma. As there were no significant differences in stage distribution and survival, especially in advanced stage, we suggest that more studies are needed to segregate these patients into distinct disease entities.

15.  Comparative study of neoadjuvant chemotherapy before radical hysterectomy and radical surgery alone in stage IB2-IIA bulky cervical cancer 
Objective
To compare the efficacy of neoadjuvant chemotherapy with paclitaxel plus platinum followed by radical hysterectomy with radical surgery alone in patients with stage IB2-IIA bulky cervical cancer.
Methods
From November 1999 to September 2007, stage IB2-IIA cervical cancers with tumor diameter >4 cm, as measured by MRI, were managed with two cycles of preoperative paclitaxel and platinum. As a control group, we selected 35 patients treated with radical surgery alone.
Results
There were no significant between group differences in age, tumor size, FIGO stage, level of SCC Ag, histopathologic type and grade. Operating time, estimated blood loss, the number of lymph nodes yielded and the rate of complications were similar in the two groups. In surgical specimens, lymph-vascular space invasion (LVSI), nodal metastasis and parametrial involvement did not differ significantly between the two groups. In the neoadjuvant group, pathologic tumor size was significantly smaller and fewer patients had deep cervical invasion. Radiotherapy, alone and in the form of concurrent chemoradiation, was administered to more patients treated with radical surgery alone (82.9% vs. 52.9%, p=0.006). No recurrence was observed in patients who could avoid adjuvant radiotherapy owing to improved risk factors after neoadjuvant chemotherapy. There were no significant differences in 5-year disease free and overall survival.
Conclusion
As neoadjuvant chemotherapy would improve pathologic prognostic factors, adjuvant radiotherapy can be avoided, without worsening the prognosis, in patients with locally advanced bulky cervical cancer. Neoadjuvant chemotherapy would be improving the quality of life after radical hysterectomy in patients with bulky cervical cancer.

16.  Stage IIIC epithelial ovarian cancer classified solely by lymph node metastasis has a more favorable prognosis than other types of stage IIIC epithelial ovarian cancer 
Journal of Gynecologic Oncology  2008;19(4):223-228.
Objective
To verify whether it can be justified to classify patients to stage IIIC epithelial ovarian cancer based on nodal involvement only.
Methods
This study included all consecutive patients with stage IIIC epithelial ovarian cancer who underwent upfront cytoreductive surgery according to the FIGO guideline followed by platinum based chemotherapy from September 1989 to September 2006 at Asan Medical Center.
Results
During the study period, a total of 272 patients met the inclusion criteria. Optimal cytoreduction was achieved in 213 patients, and complete cytoreduction was achieved in 85 patients. Median follow-up time was 37 months (range, 6-181 months). The 5-year disease free survival (DFS) and overall survival (OS) rate of all patients were 23% and 57%, respectively. Forty-one patients were allocated to stage IIIC by positive nodes only. Patients with stage IIIC disease due to positive nodes only had significantly longer DFS and OS compared to other stage IIIC patients (p<0.001 and p<0.001). The DFS and OS of these patients was significantly better than those of other stage IIIC patients who achieved complete or optimal cytoreduction (p<0.001 and p<0.001). The outcome was even better than that of stage IIIA and IIIB patients (p<0.05 and p<0.05).
Conclusion
Patients with stage IIIC epithelial ovarian cancer due to positive nodes only had a more favorable prognosis compared to other stage IIIC patients. Therefore, reevaluation of the current FIGO staging system for stage IIIC epithelial ovarian cancer is required.
