Objective@#To investigate the health-related quality of life (HRQOL) related to hyperthermic intraperitoneal chemotherapy (HIPEC) following primary or interval cytoreductive surgery for primary ovarian cancer. @*Methods@#Between 2010 and 2016, a total of 184 patients were randomly assigned to receive cytoreductive surgery with HIPEC (n=92) or without HIPEC (n=92). Quality of life (QOL) assessment was evaluated at baseline (before surgery); on postoperative day 7; after the 3rd and 6th cycle of adjuvant chemotherapy; and at 3, 6, 9, and 12 months after randomization. Patient-reported QOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) core questionnaire (EORTC-QLQ-C30), ovarian cancer questionnaire modules (QLQ-OV28), and the MD Anderson Symptoms Inventory (MDASI). @*Results@#Of the 184 patients enrolled, 165 (83/92 in the HIPEC group and 82/92 in the control group) participated in the baseline QOL assessment. There were no statistically significant differences in functional scales and symptom scales in QLQ-C30; symptom scales, including gastrointestinal symptoms QLQ-OV28; and severity and impact score in MDASI between the 2 treatment groups until 12 months after randomization. @*Conclusion@#HIPEC with cytoreductive surgery showed no statistically significant difference in HRQOL outcomes. Thus, implementation of HIPEC during either primary or interval cytoreductive surgery does not impair HRQOL.
RÉSUMÉ
Background@#The optimal treatment of BRCA wild-type patients with platinum-sensitive recurrent ovarian cancer remains unknown. Recently, there is an increase in the evidence to support the role of the combination of a poly(adenosine diphosphate-ribose) polymerase inhibitor, anti-angiogenic agents, and immunotherapy as maintenance therapy in BRCA wild-type patients with platinum-sensitive recurrence. We hypothesized that adding pembrolizumab and bevacizumab to olaparib maintenance can increase progression-free survival (PFS) in BRCA wild-type patients with platinum-sensitive recurrent ovarian cancer. @*Methods@#BRCA wild-type patients who received two previous courses of platinum-containing therapy, achieved complete or partial response to last treatment, and the treatment-free interval is >6 months after the penultimate platinum-based chemotherapy offered olaparib maintenance with pembrolizumab and bevacizumab. Forty-four patients will be included from 4 sites across Singapore and Korea. The primary endpoint of the study is 6-month PFS rate.

Purpose@#Distal radius fractures in youth are treated conservatively in most cases, but there are some cases of redisplacement in the follow-up period after cast immobilization, even after complete reduction. This study examined the risk factors of redisplacement in reduced unstable distal radius fractures. @*Materials and Methods@#From February 2011 to June 2018, 44 unstable distal radius fractures were managed with a closed reduction and cast immobilization. The patients were aged between 6 and 14 years. The cases of redisplacement were analyzed with the fracture characteristics (fracture obliquity, fracture level ratio, ulnar fracture combined), cast qualities (gap index, cast index, 3 point index, and radius-2nd metacarpal angle) and host factors (age, sex). @*Results@#The mean angulation in the union was 9.2° (0°–32.8°). In the categorical grouping 29 cases were within 10° angulation, and 15 cases were more than 10°. No significant differences in the factors of the cast indices or host factors were noted. The meaningful factor was the fracture level calculated by the relative width of the fracture site divided by the sum of width of diaphysis and epiphysis (p=0.001) and combined ulnar fracture (p=0.019). @*Conclusion@#Unstable distal radius fractures should be treated with more stubborn guidelines lest the fracture loses its anatomical alignment. In particular, in patients with less remodeling power, operative treatment would secure a better result if the fracture occurs in a more proximal location.

Purpose@#The BRCA1 or BRCA2 gene is transmitted in an autosomal dominant fashion, and genetic testing of first-degree relatives of patients with family-specific mutation (FSM) is recommended. This study examined factors affecting the uptake of FSM testing among relatives of patients with peritoneal, ovarian, or fallopian tube (POFT) cancer with confirmed BRCA1 or BRCA2 germline mutation. @*Materials and Methods@#Data from medical charts of 392 eligible patients and their relatives who had undergone outpatient genetic counseling/testing were retrospectively reviewed. Clinical factors were compared between family members who had and had not undergone genetic counseling/testing. @*Results@#The uptake of FSM testing was 30.5% (129/423) among first-degree living relatives and 53.5% (69/129) within the overall family unit. The average time from genetic testing of the proband to the first FSM test within a family was 168 days (range, 23 to 681 days). Having a living father (33.8% vs. 13.3%, p=0.007) and daughter (79.4% vs. 60.3%, p=0.019) increased the uptake of FSM testing. FSM testing was more likely among female than among male relatives of cancer patients (40.9% vs. 17.6%, p < 0.001). @*Conclusion@#Approximately one-third of first-degree relatives of patients with a POFT cancer with BRCA1 or BRCA2 mutation underwent FSM testing. Having a living father or daughter was a factor affecting the uptake of FSM testing, which was higher among female than among male relatives of the proband. This discrepancy might be due to a misconception that the BRCA gene is associated with women rather than with men.
RÉSUMÉ
Purpose@#Salvage second-line chemotherapy is usually recommended for patients with advanced epithelial ovarian cancer (AEOC) who develop progressive disease (PD) after neoadjuvant chemotherapy (NAC). Herein, we investigated the role of cytoreductive surgery (CRS) for such patients. @*Materials and Methods@#We retrospectively reviewed the medical records of 36 patients with AEOC who developed PD after receiving NAC at two tertiary academic centers with different treatment strategies between 2001 and 2016. Patients who developed PD after NAC were consistently treated with CRS at one hospital (group A; n=13) and second-line chemotherapy at another (group B;n=23). The clinical characteristics and treatment outcomes were compared between the groups. @*Results@#Overall survival (OS) was longer in group A than in group B (19.4 months vs. 7.9 months; p=0.011). High-grade serous histology was associated with longer OS than non-high-grade serous types. In group A, optimal surgery resection (<1 cm) was achieved after CRS in 6 patients (46%). Multivariate analysis showed that the treatment option was the only independent predictive factor for OS (hazard ratio, 2.30; 95% confidence interval, 1.02–5.17; p=0.044). @*Conclusion@#CRS may result in a survival benefit even in patients with AEOC who develop PD after NAC.

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

RÉSUMÉ
Purpose@#High rate of false-positive tests is a major obstacle to use human papillomavirus (HPV) detectionas a diagnostic tool for high-grade squamous intraepithelial lesions or cervical cancer(HSIL+). We investigated whether type-specific viral load or physical state of HPV 16, 18,and 58 are useful biomarkers for HSIL+. @*Materials and Methods@#Type-specific viral loads of E6 and E2 genes in cervical cells from 240, 83, and 79 HPV 16–,18–, and 58–infected women, respectively, were determined using real-time polymerasechain reaction. Viral loads were normalized to cellular DNA (copy/cell). Total and integratedviral loads and physical state were compared between HSIL+ and controls, and diagnosticvalue was determined using receiver operating characteristic analysis. @*Results@#Viral loads of HPV 16, 18, and 58 were significantly different in lesions in the same pathologicgrade. High type-specific total viral loads were significantly associated with HSIL+ (oddsratio [OR], 14.065, 39.472, and 7.103 for HPV 16, 18, and 58, respectively). High integratedviral load was related to HSIL+ in women with HPV 16 (OR, 8.242), and integrated statewas associated with HSIL+ in women with HPV 18 (OR, 9.443). Type-specific total viral loadwas significantly associated with HSIL+ (area under curve, 0.914, 0.937, and 0.971 forHPV 16, 18, and 58, respectively), indicating an excellent performance in detecting HSIL+. @*Conclusion@#Type-specific total viral load may be a powerful diagnostic marker for HSIL+ in HPV 16–,18–, and 58–infected HSIL+ lesions. If demonstrated in all other high-risk HPV types, thismethod can lead to a paradigm shift in the strategy of equivocal cytologic abnormalities.
RÉSUMÉ
PURPOSE: The purpose of this study was to investigate decision patterns to reduce the risks of BRCArelated breast and gynecologic cancers in carriers of BRCA pathogenic variants. We found a change in risk-reducing (RR) management patterns after December 2012, when the National Health Insurance System (NHIS) of Korea began to pay for BRCA testing and riskreducing salpingo-oophorectomy (RRSO) in pathogenic-variant carriers. MATERIALS AND METHODS: The study group consisted of 992 patients, including 705 with breast cancer (BC), 23 with ovarian cancer (OC), 10 with both, and 254 relatives of high-risk patients who underwent BRCA testing at the National Cancer Center of Korea from January 2008 to December 2016.We analyzed patterns of and factors in RR management. RESULTS: Of the 992 patients, 220 (22.2%) were carriers of BRCA pathogenic variants. About 92.3% (203/220) had a family history of BC and/or OC,which significantly differed between BRCA1 and BRCA2 carriers (p < 0.001). All 41 male carriers chose surveillance. Of the 179 female carriers, 59 of the 83 carriers (71.1%) with BC and the 39 of 79 unaffected carriers (49.4%) underwent RR management. None of the carriers affected with OC underwent RR management. Of the management types, RRSO had the highest rate (42.5%) of patient choice. The rate of RR surgery was significantly higher after 2013 than before 2013 (46.3% [74/160] vs. 31.6% [6/19], p < 0.001). CONCLUSION: RRSO was the preferred management for carriers of BRCA pathogenic variants. The most important factors in treatment choice were NHIS reimbursement and/or the severity of illness.

PURPOSE: The purpose of this study was to develop Korean versions of the National Comprehensive Cancer Network/Functional Assessment of Cancer Therapy (NCCN-FACT) Ovarian Symptom Index-18 (NFOSI-18) and FACT/Gynecologic Oncology Group (FACT-GOG) Neurotoxicity 4-item (NTX-4), evaluating their reliability and reproducibility. MATERIALS AND METHODS: In converting NFOSI-18 and NTX-4, the following steps were performed: forward translation, backward translation, expert review, pretest of preliminary format, and finalization of Korean versions (K-NFOSI-18 and K-NTX-4). Patients were enrolled from six institutions where each had completed chemotherapy for ovarian, tubal, or peritoneal cancer at least 1 month earlier. In addition to demographics obtained by questionnaire, all subjects were assessed via K-NFOSI-18, K-NTX-4, and a Korean version of the EuroQoL-5 Dimension. Internal structural validity and reliability were evaluated using item internal consistency, item discriminant validity, and Cronbach's α. To evaluate test-retest reliability, K-NFOSI-18 and K-NTX-4 were readministered after 7-21 days, and intraclass correlation coefficients (ICCs) were calculated. RESULTS: Of the 250 women enrolled during the 3-month recruitment period, 13 withdrew or did not respond, leaving 237 (94.8%) for the analyses. Mean patient age was 54.3±10.8 years. Re-testing was performed in 190 patients (80.2%). The total K-NFOSI-18 and K-NTX-4 scores were 49 (range, 20 to 72) and 9 (range, 0 to 16), respectively, with high reliability (Cronbach's α=0.84 and 0.89, respectively) and reproducibility (ICC=0.77 and 0.84, respectively) achieved in retesting. CONCLUSION: Both NFOSI-18 and NTX-4 were successfully developed in Korean with minimal modification. Each Korean version showed high internal consistency and reproducibility.

OBJECTIVE: To compare the survival outcomes of adjuvant radiotherapy and chemotherapy in women with uterine-confined endometrial cancer with uterine papillary serous carcinoma (UPSC) or clear cell carcinoma (CCC). METHODS: Medical records of 80 women who underwent surgical staging for endometrial cancer were retrospectively reviewed. Stage I UPSC and CCC were pathologically confirmed after surgery. Survival outcomes were compared between the adjuvant radiotherapy and chemotherapy groups. RESULTS: Fifty-four (67.5%) and 26 (32.5%) women had UPSC and CCC, respectively. Adjuvant therapy was administered to 59/80 (73.8%) women (25 radiotherapy and 34 chemotherapy). High preoperative serum cancer antigen-125 level (25.1±20.2 vs. 11.5±6.5 IU/mL, p 0.999) and overall survival (77.5% vs. 87.8%, p=0.373) rates were similar between the groups. Neither radiotherapy (hazard ratio [HR]=1.810; 95% confidence interval [CI]=0.297–11.027; p=0.520) nor chemotherapy (HR=1.638; 95% CI=0.288–9.321; p=0.578) after surgery was independently associated with disease recurrence. CONCLUSION: Our findings showed similar survival outcomes for adjuvant radiotherapy and chemotherapy in stage I UPSC and CCC of the endometrium. Further large study with analysis stratified by MI or LVSI is required.

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

PURPOSE: Recently, there has been increasing number of trampoline injuries at our pediatric orthopedic clinic and emergency room. Therefore, this study is to analyze the prevalence of the trampoline injuries with emergency room surveillance. MATERIALS AND METHODS: Between September 2015 and February 2017, all patients under the age of 15 years, who visited emergency room of a teaching hospital with trauma and referred to the department of orthopedic surgery, was included; the cause of trauma was analyzed. The severity of injury was also evaluated and compared according to the cause of injury. RESULTS: There were a total of 1,807 patients under the age of 15 years who visited our emergency room during the study period. There were a total of 71 trampoline injuries (3.9%). There were 28 patients below the age of 5 years, and among them, 14 minor injury were recorded; 43 patients were over the age of 5 years and with 4 minor, 20 moderate, and 19 severe injuries. In the age between 5 and 15 years, the prevalence of mild injury was lower in trampoline injury compared with those of other sports injuries (9.3% vs. 34.0%) and the prevalence of severe injury was higher in trampoline injury (44.2% vs. 26.3%) (p=0.002). CONCLUSION: Our findings indicate that the incidence of trampoline injury was lower than other country, but it was more severe than injuries from other sports. With increasing incidence of trampoline injuries, parents should be more mindful that trampolines are not safe and stricter supervision may be necessary.

BACKGROUND: The purpose of this study was to assess the relevance of preoperative magnetic resonance imaging (MRI) evaluation by occupation ratio (OR) at maximum diameter of supraspinatus muscle. METHODS: Patients from the Inje University Sanggye Paik Hospital who received rotator cuff repair and underwent pre- and postoperative MRI were selected as subjects of this study. On T1-weighted MRIs, OR of fat and muscle at Y-shaped view, OR at a location on supraspinatus muscle where its diameter was maximum on coronal view, and pre- and postoperative Goutallier Classification and changes in the tangent sign were measured. Statistical significance of postoperative OR was assessed regarding time from symptom onset to surgery, size of rotator cuff tear, preoperative OR, and the difference between ORs measured at maximum diameter of supraspinatus muscle and Y-shaped view. RESULTS: Preoperative OR at Y-shaped view was 52.28 ± 8.57 (32.5–65.3). Preoperative OR difference between maximum diameter and Y-shaped view was 13.76 ± 10.51 (2.38–42.04), and Pearson correlation coefficient was 0.604 (p=0.001). Postoperative OR at Y-shaped view was 63.77 ± 9.35 (37.3–76.1). Pearson correlation coefficient of pre- and postoperative Goutallier Classification was −0.579 (p=0.002) and Pearson correlation coefficient of the postoperative difference between ORs measured at maximum diameter of supraspinatus muscle and Y-shaped view was −0.386 (p=0.047). CONCLUSIONS: Fatty degeneration of supraspinatus muscle in rotator cuff tear patients should be evaluated not only in the conventional Y-shaped view, but also at location of maximum diameter of supraspinatus muscle to establish patients' therapeutic plan.

BACKGROUND: This study retrospectively investigated outcomes following dental implantation in patients with special needs who required general anesthesia to enable treatment. METHODS: Patients underwent implant treatment under general anesthesia at the Clinic for the Disabled in Seoul National University Dental Hospital between January 2004 and June 2017. The study analyzed medical records and radiographs. Implant survival rates were calculated by applying criteria for success or failure. RESULTS: Of 19 patients in the study, 8 were males and 11 were females, with a mean age of 32.9 years. The patients included 11 with mental retardation, 3 with autism, 2 with cerebral palsy, 2 with schizophrenia, and 1 with a brain disorder; 2 patients also had seizure disorders. All were incapable of oral self-care due to serious cognitive impairment and could not cooperate with normal dental treatment. A total of 27 rounds of general anesthesia and 1 round of intravenous sedation were performed for implant surgery. Implant placement was performed in 3 patients whose prosthesis records could not be found, while 3 other patients had less than 1 year of follow-up after prosthetic treatment. When the criteria for implant success or failure were applied in 13 remaining patients, 3 implant failures occurred in 59 total treatments. The cumulative survival rate of implants over an average of 43.3 months (15-116 months) was 94.9%. CONCLUSIONS: For patients with severe cognitive impairment who are incapable of oral self-care, implant treatment under general anesthesia showed a favorable prognosis.

OBJECTIVE: The Gynecologic Cancer Lymphedema Questionnaire (GCLQ) was designed to identify gynecologic cancer patients with lower limb lymphedema (LLL). The questionnaire consists of 20 items distributed over 7 symptom clusters. The present study aimed to develop an abridged form of the GCLQ for simpler screening and more effective follow-up of LLL. METHODS: Data that had been collected for the development and validation of the Korean version of the GCLQ (GCLQ-K) were used in this study. Receiver-operating characteristic (ROC) curves were drawn according to the individual items of the GCLQ-K. Based on discrimination ability, the candidate items were selected in each symptom cluster. After combining the items, the best model was identified and named GCLQ-7. The area under the ROC curve (AUC) was compared between the GCLQ-7 and the original GCLQ-K. RESULTS: In total, 11 candidate items were selected from the original GCLQ-K. Among the models made with the candidate items, GCLQ-7, the best model, was constructed with 7 items as follows: 1) limited knee movement, 2) general swelling, 3) redness, 4) firmness/tightness, 5) groin swelling, 6) heaviness, and 7) aching. This model exhibited an AUC of 0.945 (95% confidence interval [CI], 0.900–0.991), which is comparable with that of the original GCLQ-K (AUC, 0.867; 95% CI, 0.779–0.956). The best cutoff value was 2 points, at which the sensitivity and specificity were 97.0% and 76.5%, respectively. CONCLUSION: The newly developed short version model, GCLQ-7, showed acceptable discrimination ability as compared with the original GCLQ-K.

Calcifying cystic odontogenic tumor (CCOT) is defined as an odontogenic cyst-like benign neoplasm that characteristically contains several ghost cells, ameloblastoma-like epithelium, and occasional calcification. Ghost cell odontogenic carcinoma (GCOC), a malignant form of CCOT, is an exceptionally rare malignant tumor. In this report, we present a case of a 53-year-old man whose chief complaint was a solitary mass on the right mandible area. The mass was completely removed through an extraoral surgical approach and reconstructive surgery was performed in two phases.

OBJECTIVE: To investigate the survival outcomes in patients with bulky stage IIIC and IV ovarian cancer, treated by primary debulking surgery (PDS) and selective use of neoadjuvant chemotherapy (NAC) according to institutional criteria. METHODS: Medical records for advanced ovarian cancer patients who were treated at National Cancer Center (NCC) between December 2000 and March 2009 were retrospectively reviewed in the comprehensive cancer center. Bulky stage IIIC and IV ovarian cancer cases were included. Current NCC indication for NAC is determined based on patients' performance status and/or computerized tomography (CT) findings indicating difficult cytoreduction. After NAC, all traces of regressed metastatic ovarian cancer, potentially including chemotherapy-resistant cancer cells, were surgically removed. RESULTS: Of the 279 patients with bulky stage IIIC and IV, 143 (51%) underwent PDS and 136 (49%) received NAC. No gross residual and residual tumor measuring ≤1 cm was achieved in 66% and 96% of the PDS group and 79% and 96% of the NAC group, respectively. The median progression-free survival (PFS) and overall survival (OS) time were 20 months and not reached, but might be estimated more than 70 months in the PDS group and 15 and 70 months in the NAC group, respectively. CONCLUSION: Extensive cytoreductive surgery to minimize residual tumor and selective use of NAC based on the institutional criteria could result in improved survival outcomes. Until further studies can be done to define the selection criteria for NAC after surgery, institutional criteria for NAC should consider the ability of the surgeon and institutional capacity.

OBJECTIVE: To evaluate the clinical and pathologic factors associated with survival in patients with neuroendocrine cervical carcinoma (NECC). METHODS: The records of 61 patients with NECC diagnosed between 2000 and 2014 at Seoul National University Hospital and the National Cancer Center were retrospectively reviewed. Kaplan-Meier and Cox regression methods were used for analyses. RESULTS: Of the 61 patients, 67.2% were diagnosed at early stage (I to IIA) with a median age of 49 years. Of those, 78% underwent surgery and 75.6% received postoperative adjuvant treatment. For patients diagnosed at advanced stage, 60.0% received chemotherapy only and 25.0% received concurrent chemoradiation therapy. In the univariate analysis, advanced stage (77 vs. 40 months, P=0.013), tumor size ≥2 cm (133 vs. 47 months, P=0.002) and mixed tumor (101 vs. 34 months, P=0.004) were shown to be poor prognostic factors. In the multivariate analysis, tumor stage, tumor size and tumor homology were shown to be independent prognostic factors for overall survival. Of the total, 39.3% of the patients experienced recurrence, and 54.1% of the patients had metastasis. Of the patients diagnosed at early stage, 51.2% experienced recurrence. CONCLUSION: Tumor stage, tumor size and tumor homology were found to be independent prognostic factors in patients with NECC. Even in patients diagnosed at early stage, recurrence and distant metastasis were frequently observed.
