ABSTRACT
Purpose@#This study aimed to investigate the impact of BRCA1/2 mutational status on survival outcomes in patients with platinum-sensitive relapsed (PSR) epithelial ovarian cancer (EOC). @*Materials and Methods@#We retrospectively identified patients who received secondary treatment for PSR EOC at our institution between January 2007 and June 2021 and who underwent BRCA1/2 gene testing by either germline or somatic methods. The association between BRCA1/2 mutational status and survival outcomes was evaluated. Both secondary cytoreductive surgery (CRS) and maintenance therapy were stratified considering real-world clinical practice. @*Results@#Of 262 patients, 91 (34.7%) and 171 (65.3%) were assigned to BRCA1/2 mutation and wild-type groups, respectively. The two groups had similar proportions of patients undergoing secondary CRS (26.4% vs. 32.7%, p=0.286) and maintenance therapy (54.9% vs. 46.2%, p=0.178). Overall, no differences in progression-free survival (PFS; median, 19.7 vs. 15.1 months, p=0.120) and overall survival (OS; p=0.400) were observed between the two groups. In multivariate analyses, BRCA1/2 mutational status was not associated with PFS (adjusted hazard ratio, 0.816; 95% confidence interval, 0.596 to 1.119; p=0.207). BRCA1/2 mutational status did not affect PFS among patients who underwent secondary CRS (n=80) and among those who did not (n=182) (p=0.074 and p=0.222, respectively). PFS did not differ in the BRCA1/2 mutational status among the patients who received bevacizumab maintenance (n=90, p=0.992). @*Conclusion@#In this real-world evidence study, BRCA1/2 mutational status itself was not associated with PFS and OS in PSR EOC, which was consistent with whether secondary CRS or not and with bevacizumab maintenance.
ABSTRACT
Purpose@#This study aimed to compare treatment outcomes and toxicity profile between imaged-guided brachytherapy (IGBT) versus conventional brachytherapy (CBT) performed by the same practitioner during the same time period. @*Materials and Methods@#Medical records of 104 eligible patients who underwent brachytherapy for locally advanced cervical cancer were retrospectively reviewed. Fifty patients (48.1%) underwent IGBT, and 54 (51.9%) patients underwent CBT. All patients underwent concurrent chemoradiation with cisplatin. High-dose-rate intracavitary brachytherapy with dose prescription of 25-30 Gy in 4-6 fractions was performed for all patients. Late lower gastrointestinal (GI) and urinary toxicities occurred more than 3 months after the end of brachytherapy were included for comparative and dosimetric analyses. @*Results@#The median follow-up period was 18.33 months (range, 3.25 to 38.43 months). There were no differences in oncologic outcomes between the two groups. The IGBT group had lower rate of actuarial grade ≥ 3 toxicity than the CBT group (2-year, 4.5% vs. 25.7%; p=0.030). Cumulative equieffective D2cc of sigmoid colon was significantly correlated with grade ≥ 2 lower GI toxicity (p=0.033), while equieffective D2cc of rectum (p=0.055) and bladder (p=0.069) showed marginal significance with corresponding grade ≥ 2 toxicities in the IGBT group. Half of grade ≥ 3 lower GI toxicities impacted GI tract above the rectum. Optimal thresholds of cumulative D2cc of sigmoid colon and rectum were 69.7 Gy and 70.8 Gy, respectively, for grade ≥ 2 lower GI toxicity. @*Conclusion@#IGBT showed superior toxicity profile to CBT. Evaluating the dose to the GI tract above rectum by IGBT might prevent some toxicities.
ABSTRACT
Purpose@#To determine whether the prognostic impact of lymph node ratio (LNR), defined as the ratio between the number of positive lymph nodes and removed lymph nodes, differs between open and minimally invasive surgical approaches for radical hysterectomy (RH) in node-positive, early-stage cervical cancer. @*Materials and Methods@#We retrospectively identified 2009 International Federation of Gynecology and Obstetrics stage IB1-IIA2 patients who underwent primary type C RH between 2010 and 2018. Among them, only those with pathologically proven lymph node metastases who received adjuvant radiation therapy were included. The prognostic significance of LNR was investigated according to open surgery and minimally invasive surgery (MIS). @*Results@#In total, 55 patients were included. The median LNR (%) was 9.524 (range, 2.083–62.500). Based on receiver operating characteristic curve analysis, the cut-off value for LNR (%) was determined as 8.831. Overall, patients with high LNR (≥8.831%;n=29) showed worse disease-free survival (DFS) than those with low LNR (<8.831%, n=26) (p=0.027), whereas no difference in overall survival was observed. Multivariate analyses adjusting for clinicopathologic factors revealed that DFS was adversely affected by both MIS [adjusted hazard ratio (HR), 8.132; p=0.038] and high LNR (adjusted HR, 10.837; p=0.045). In a subgroup of open surgery cases, LNR was not associated with disease recurrence. However, in a subgroup of MIS cases, high LNR was identified as an independent poor prognostic factor for DFS (adjusted HR, 14.578; p=0.034). @*Conclusion@#In patients with node-positive, early-stage cervical cancer, high LNR was associated with a significantly higher disease recurrence rate. This relationship was further consolidated among patients who received MIS RH.
ABSTRACT
Purpose@#This study aimed to present a single institutional experience with BRCA1/2 gene tests and the effects of pathogenic mutations in epithelial peritoneal, ovarian, and fallopian tube cancer (POFTC) on survival outcomes. @*Materials and Methods@#We identified patients with epithelial POFTCs who underwent BRCA1/2 gene testing by either germline or somatic methods between March 2007 and March 2020. Based on the BRCA1/2 test results, patients were divided into BRCA mutation and wild-type groups, followed by comparisons of clinicopathologic characteristics and survival outcomes after primary treatment. @*Results@#The annual number of POFTC patients who received BRCA1/2 gene tests increased gradually. In total, 511 patients were included and BRCA1/2 mutations were observed in 143 (28.0%). Among 57 patients who received both germline and somatic tests, three (5.3%) showed discordant results from the two tests. Overall, no differences in progression-free survival (PFS; p=0.467) and overall survival (p=0.641) were observed between the BRCA mutation and wild-type groups; however, multivariate analyses identified BRCA1/2 mutation as an independent favorable prognostic factor for PFS (adjusted hazard ratio [aHR], 0.765; 95% confidence interval [CI], 0.593 to 0.987; p=0.040). In 389 patients with International Federation of Gynecology and Obstetrics stage III-IV, different results were shown depending on primary treatment strategy: while BRCA1/2 mutation significantly improved PFS in the subgroup of neoadjuvant chemotherapy (aHR, 0.619; 95% CI, 0.385 to 0.995; p=0.048), it did not affect patient PFS in the subgroup of primary debulking surgery (aHR, 0.759; 95% CI, 0.530 to 1.089; p=0.135). @*Conclusion@#BRCA1/2 mutations are frequently observed in patients with epithelial POFTCs, and such patients showed better PFS than did those harboring wild-type BRCA1/2.

PURPOSE: The purpose of this study was to examine the effect of laughter therapy on depression, anxiety, fatigue, and quality of sleep in gastrointestinal cancer survivors. METHODS: This study was a randomized controlled trial. We compared the effect of laughter therapy with usual care only in post chemotherapy gastrointestinal patients. Outcomes included changes in depression and anxiety (according to the Hospital Anxiety and Depression Scale), fatigue (according to the Fatigue Severity Scale), and quality of sleep (according to the Verran & Synder-Halpern Sleep Scale). Data was collected July 2015 through January 2016. Seventy nine participants who agreed to participate in this study were randomized to either the experimental group (n=40) or the control group (n=39). Therapy included eight sessions (60 minutes each, once weekly). Data were analyzed using the Windows SPSS 22.0 program. RESULTS: Laughter therapy was effective in reducing fatigue (p=.019) and increasing satisfaction of sleep (p=.030). There were no differences between the groups after therapy for depression (p=.129) and anxiety (p=.200). CONCLUSION: Results of this study indicate that laughter therapy may be an effective nursing intervention for improving the health status of gastrointestinal cancer survivors after chemotherapy.

PURPOSE: Discovery of models predicting the exact prognosis of epithelial ovarian cancer (EOC) is necessary as the first step of implementation of individualized treatment. This study aimed to develop nomograms predicting treatment response and prognosis in EOC. MATERIALS AND METHODS: We comprehensively reviewed medical records of 866 patients diagnosed with and treated for EOC at two tertiary institutional hospitals between 2007 and 2016. Patients’ clinico-pathologic characteristics, details of primary treatment, intra-operative surgical findings, and survival outcomes were collected. To construct predictive nomograms for platinum sensitivity, 3-year progression-free survival (PFS), and 5-year overall survival (OS), we performed stepwise variable selection by measuring the area under the receiver operating characteristic curve (AUC) with leave-one-out cross-validation. For model validation, 10-fold cross-validation was applied. RESULTS: The median length of observation was 42.4 months (interquartile range, 25.7 to 69.9 months), during which 441 patients (50.9%) experienced disease recurrence. The median value of PFS was 32.6 months and 3-year PFS rate was 47.8% while 5-year OS rate was 68.4%. The AUCs of the newly developed nomograms predicting platinum sensitivity, 3-year PFS, and 5-year OS were 0.758, 0.841, and 0.805, respectively. We also developed predictive nomograms confined to the patients who underwent primary debulking surgery. The AUCs for platinum sensitivity, 3-year PFS, and 5-year OS were 0.713, 0.839, and 0.803, respectively. CONCLUSION: We successfully developed nomograms predicting treatment response and prognosis of patients with EOC. These nomograms are expected to be useful in clinical practice and designing clinical trials.

OBJECTIVE: Uterine leiomyosarcoma (LMS) is a rare and aggressive disease with poor outcome. Due to its rarity and conflict of data, investigation on finding prognostic factor is challenging. The aim of the study was to investigate the prognostic significance of preoperative ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) in uterine LMS. METHODS: This was a retrospective observational cohort study in 3 tertiary referral hospitals. We retrospectively evaluated data from patients with pathologically proven uterine LMS who underwent preoperative ¹⁸F-FDG PET/CT scans at 3 institutions. The prognostic implication of PET/CT parameters and other clinico-pathological parameters on disease-free survival (DFS) and overall survival (OS) was evaluated. RESULTS: Clinico-patholgical data were reviewed for 19 eligible patients. In the group overall, median DFS and OS were 12 and 20 months, respectively. As for the recurrence, large tumor size, and high tumor maximum standardized uptake value (SUVmax) were demonstrated as risk factors of recurrence. As for the OS, high tumor SUVmax was demonstrated as the unique risk factor. There were significant differences in tumor size, mitotic count, SUVmax, and DFS between patients with and without recurrence. Also, there were significant differences in tumor size, SUVmax, DFS, and OS between 2 subgroups stratified by cut-off SUVmax. CONCLUSION: SUVmax at preoperative ¹⁸F-FDG PET/CT was associated with worse outcome in patients with uterine LMS. In the preoperative setting, SUVmax can be a valuable non-invasive prognostic marker. Additionally, SUVmax can help identify highly aggressive uterine LMS and may help in adjusting standard treatment toward an individualized, risk-adapted treatment.

Clinical practice guidelines for gynecologic cancers have been developed by academic society from several countries. Each guideline reflected their own insurance system and unique medical environment, based on the published evidence. 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 develop the third edition of the guidelines in an advanced format based on evidence-based medicine, embracing up-to-date clinical trials and qualified Korean data. These guidelines cover strategies for diagnosis and treatment of primary and recurrent cervical cancer. The committee members and many gynecologic oncologists derived key questions through discussions, and a number of relevant scientific literature were reviewed in advance. Recommendations for each specific question were developed by the consensus conference, and they are summarized here, along with the details. The objective of these practice guidelines is to establish standard policies on issues in clinical practice related to the management in cervical cancer based on the results in published papers to date and the consensus of experts as a KSGO Consensus Statement.

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.

PURPOSE: We compared the predictive and prognostic values of leukocyte differential counts, systemic inflammatory (SIR) markers and cancer antigen 125 (CA-125) levels, and identified the most useful marker in patients with ovarian clear cell carcinoma (OCCC). MATERIALS AND METHODS: The study included 109 patients with OCCC who did not have any inflammatory conditions except endometriosis, and underwent primary debulking surgery between 1997 and 2012. Leukocyte differential counts (neutrophil, lymphocyte, monocyte, eosinophil, basophil, and platelet), SIR markers including neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), and platelet to lymphocyte ratio (PLR), and CA-125 levels were estimated to select potential markers for clinical outcomes. RESULTS: Among potential markers (neutrophil, monocyte, platelet, NLR, MLR, PLR, and CA-125 levels) selected by stepwise comparison, CA-125 levels were best at predicting advanced stage disease, suboptimal debulking and platinum-resistance (cut-off values, > or = 46.5, > or = 11.45, and > or = 66.4 U/mL; accuracies, 69.4%, 78.7%, and 68.5%) while PLR > or = 205.4 predicted non-complete response (CR; accuracy, 71.6%) most accurately. Moreover, PLR < 205.4 was an independent factor for the reduced risk of non-CR (adjusted odds ratio, 0.17; 95% confidence interval [CI], 0.04 to 0.69), and NLR < 2.8 was a favorable factor for improved progression-free survival (PFS; adjusted hazard ratio, 0.49; 95% CI, 0.25 to 0.99) despite lack of a marker for overall survival among the potential markers. CONCLUSION: CA-125 levels may be the most useful marker for predicting advanced-stage disease. Suboptimal debulking and platinum-resistance, and PLR and NLR may be most effective to predict non-CR and PFS in patients with OCCC.

OBJECTIVE: We investigated the prognostic value of intratumoral [18F]fluorodeoxyglucose (FDG) uptake heterogeneity (IFH) derived from positron emission tomography/computed tomography (PET/CT) in patients with cervical cancer. METHODS: Patients with uterine cervical cancer of the International Federation of Obstetrics and Gynecology (FIGO) stage IB to IIA were imaged with [18F]FDG PET/CT before radical surgery. PET/CT parameters such as maximum and average standardized uptake values (SUV(max) and SUV(avg)), metabolic tumor volume (MTV), total lesion glycolysis (TLG), and IFH were assessed. Regression analyses were used to identify clinicopathological and imaging variables associated with progression-free survival (PFS). RESULTS: We retrospectively reviewed clinical data of 85 eligible patients. Median PFS was 32 months (range, 6 to 83 months), with recurrence observed in 14 patients (16.5%). IFH at an SUV of 2.0 was correlated with primary tumor size (p<0.001), SUV(tumor) (p<0.001), MTV(tumor) (p<0.001), TLG(tumor) (p<0.001), depth of cervical invasion (p<0.001), and negatively correlated with age (p=0.036). Tumor recurrence was significantly associated with TLG(tumor) (p<0.001), MTV(tumor) (p=0.001), SUV(LN) (p=0.004), IFH (p=0.005), SUV(tumor) (p=0.015), and FIGO stage (p=0.015). Multivariate analysis identified that IFH (p=0.028; hazard ratio, 756.997; 95% CI, 2.047 to 279,923.191) was the only independent risk factor for recurrence. The Kaplan-Meier survival graphs showed that PFS significantly differed in groups categorized based on IFH (p=0.013, log-rank test). CONCLUSION: Preoperative IFH was significantly associated with cervical cancer recurrence. [18F]FDG based heterogeneity may be a useful and potential predicator of patient recurrence before treatment.

OBJECTIVE: To evaluate the cost-effectiveness of nodal staging surgery before chemoradiotherapy (CRT) for locally advanced cervical cancer in the era of positron emission tomography/computed tomography (PET/CT). METHODS: A modified Markov model was constructed to evaluate the cost-effectiveness of para-aortic staging surgery before definite CRT when no uptake is recorded in the para-aortic lymph nodes (PALN) on PET/CT. Survival and complication rates were estimated based on the published literature. Cost data were obtained from the Korean Health Insurance Review and Assessment Service. Strategies were compared using an incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed, including estimates for the performance of PET/CT, postoperative complication rate, and varying survival rates according to the radiation field. RESULTS: We compared two strategies: strategy 1, pelvic CRT for all patients; and strategy 2, nodal staging surgery followed by extended-field CRT when PALN metastasis was found and pelvic CRT otherwise. The ICER for strategy 2 compared to strategy 1 was $19,505 per quality-adjusted life year (QALY). Under deterministic sensitivity analyses, the model was relatively sensitive to survival reduction in patients who undergo pelvic CRT alone despite having occult PALN metastasis. A probabilistic sensitivity analysis demonstrated the robustness of the case results, with a 91% probability of cost-effectiveness at the willingness-to-pay thresholds of $60,000/QALY. CONCLUSION: Nodal staging surgery before definite CRT may be cost-effective when PET/CT imaging shows no evidence of PALN metastasis. Prospective trials are warranted to transfer these results to guidelines.

The consensus guideline development committee of Korean Society of Gynecologic Oncology was reconvened in March 2012. The committee consisted of 36 experts representing 12 university hospitals and professional organizations. The objective of this committee was to develop standardized guidelines for cervical cancer screening tests for Korean women and to distribute these guidelines to every clinician, eventually improving the quality of medical care. Since the establishment of the consensus guideline development committee, evidence-based guidelines have either been developed de novo considering specific Korean situations or by adaptation of preexisting consensus guidelines from other countries. Recommendations for cervical cancer screening tests, management of atypical squamous and glandular cells, and management of low-grade and high-grade squamous intraepithelial lesions were developed. Additionally, recommendations for human papillomavirus DNA testing and recommendations for adolescent and pregnant women with abnormal cervical screening test results were also included.

PURPOSE: The purpose of this study is to evaluate the efficacy and toxicity of oxaliplatin, leucovorin, and 5-fluorouracil (FOLFOX-4) chemotherapy in heavily pretreated patients with recurrent epithelial ovarian cancer (EOC). MATERIALS AND METHODS: Clinical data were reviewed in 28 patients who received FOLFOX-4 as more than the second-line chemotherapy, consisting of 85 mg/m2 of oxaliplatin as a 2-hour infusion, 200 mg/m2 of leucovorin as a 2-hour infusion, and bolus 400 mg/m2 on day 1, followed by a 22-hour infusion of 600 mg/m2 of 5-fluorouracil for two consecutive days every three weeks. In addition, its efficacy and toxicity were compared with those reported in in three previous relevant studies. RESULTS: A total of 128 cycles of FOLFOX-4 were administered with the median number of five cycles (range, 1 to 10 cycles). In nine patients with measurable disease, complete response (CR) and partial response (PR) were observed in 0 (0%) and two (22.2%) patients, whereas in 19 patients with non-measurable disease, CR and PR were observed in 0 (0%) and five (26.3%) patients. Among all patients, grade 3 anemia, neutropenia, and thrombocytopenia were observed in two (7.1%), three (10.7%), and one (3.6%) patient, and grade 3 fatigue, nausea and vomiting, and peripheral neuropathy were observed in one (3.6%), two (7.1%), and three (10.7%) patients. In addition, median values of time to progressive disease and chemotherapy-specific survival were three months (range, 0 to 10 months) and nine months (range, 4 to 24 months). CONCLUSION: FOLFOX-4 is feasible as salvage chemotherapy with acceptable toxicity for heavily pretreated patients with recurrent EOC.

PURPOSE: The purpose of this study was to determine whether chemoradiation (CCR) is efficient for improving prognosis, compared with systemic chemotherapy (SC), in patients with stage IVB cervical cancer who have distant lymphatic metastasis. MATERIALS AND METHODS: Among 2,322 patients with cervical cancer between January 2000 and March 2010, 43 patients (1.9%) had stage IVB disease. After exclusion of 19 patients due to insufficient data and hematogenous metastasis, 24 patients (1%) who received CCR (n=10) or SC (n=14) were enrolled. We compared tumor response, progression-free survival (PFS) and overall survival (OS), and disease recurrence between CCR and SC. RESULTS: Complete response rates were 60% and 0% after CCR and SC (p<0.01). Grade 3 or 4 leukopenia was more common in patients treated with CCR (24.4% vs. 9.1%, p=0.03), whereas grade 3 or 4 neuropenia was more frequent in those treated with SC (28.4% vs. 11.1%, p=0.03). Development of grade 3 proctitis occurred as a late radiotherapy (RT)-related toxicity in only one patient (10%) treated with CCR. In addition, squamous cell carcinoma and CCR were favorable prognostic factors for improvement of PFS (adjusted hazard ratios [HRs], 0.17 and 0.12; 95% confidence intervals [CIs], 0.04 to 0.80 and 0.03 to 0.61), and only CCR was significant for improvement of OS (adjusted HR, 0.15; 95% CI, 0.02 to 0.90). However, no differences in the rate and pattern of disease recurrence were observed between CCR and SC. CONCLUSION: CCR may be more effective than SC for improving survival, and can be regarded as a feasible method with some caution regarding late RT-related toxicity for treatment of stage IVB cervical cancer with distant lymphatic metastasis.

OBJECTIVE: To evaluate the improvement in prognosis prediction with reassignment of International Federation of Gynecology and Obstetrics (FIGO) stages for ovarian carcinoma. METHODS: This was a retrospective study of patients with epithelial ovarian, fallopian tube, and primary peritoneal cancers. Sub-staging criteria used in stage reassignment were defined as follows: surgical spillage (IC1), capsule rupture before surgery or tumor on the surface (IC2), and positive cytology results (IC3); microscopic (IIB1) and macroscopic (IIB2) pelvic spread; microscopic extrapelvic spread (IIIA1) and retroperitoneal lymph node (LN) metastasis without extrapelvic spread (IIIA2); and supraclavicular LN metastasis (IVA) and other distant metastasis (IVB). Survival outcomes associated with the current and reassigned stages were compared. RESULTS: Overall, 870 patients were eligible for analysis. The median follow-up period was 45 months (range, 0 to 263 months). The 5-year overall survival rates (5YSRs) according to the current staging were 93.5% (IA), 82.5% (IC), 75.0% (IIB), 74.5% (IIC), 57.5% (IIIA), 54.0% (IIIB), 38.5% (IIIC), and 33.0% (IV). The 5YSRs of patients with IC1, IC2, and IC3 after sub-staging were 92.0%, 85.0%, and 71.0%, respectively (p=0.004). Patients who were reassigned to stage IIIA2 had a better 5YSR than those with extrapelvic tumors >2 cm (66.3% vs. 35.8%; p=0.005). Additionally, patients with newly assigned stage IVA disease had a significantly better 5YSR than those with stage IVB disease (52.0% vs. 28.0%; p=0.015). CONCLUSION: The modified FIGO staging for ovarian carcinoma appears superior to the current staging for discriminating survival outcomes of patients with surgical spillage, retroperitoneal LN metastasis without extrapelvic peritoneal involvement, or distant metastasis to supraclavicular LNs.

OBJECTIVE: To determine whether [18F]FDG uptake on PET/CT imaging before surgical staging has prognostic significance in patients with epithelial ovarian cancer (EOC). METHODS: Patients with EOC were imaged with integrated PET/CT before surgical staging. Hypermetabolic lesions were measured as the standardized uptake value (SUV) in primary and metastatic tumors. SUV distribution was divided into two regions at the level of umbilicus, and the impact of the ratio between above and below umbilicus (SUVlocation ratio) on progression-free survival (PFS) was examined using Cox proportional hazards regression. RESULTS: Between January 2004 and December 2009, 55 patients with EOC underwent preoperative PET/CT. The median duration of PFS was 11 months (range, 3 to 43 months), and twenty (36.4%) patients experienced recurrence. In univariate analysis, high SUVlocation ratio (p=0.002; hazard ratio [HR], 1.974; 95% confidence interval [CI], 1.286 to 3.031) was significantly associated with recurrence. Malignant mixed mullerian tumor compared with endometrioid histology was also shown to have significance. In multivariate analysis, high SUVlocation ratio (p=0.005; HR, 2.418; 95% CI, 1.1315 to 4.447) and histology (serous, mucinous, and malignant mixed mullerian tumor compared with endometrioid type) were significantly associated with recurrence. Patients were categorized into two groups according to SUVlocation ratio ( or =0.3934), and the Kaplan-Meier survival graph showed a significant difference in PFS between the groups (p=0.0021; HR, 9.47, log-rank test).

A 35-year-old woman was determined to have an ovarian cyst and underwent a right ovarian cystectomy at 10 weeks of gestation. A histopathological examination revealed follicular carcinoma arising in a teratoma. No evidence of metastasis was found after delivery. She underwent a total thyroidectomy, followed by radioactive iodine (RAI) therapy. However, her serum thyroglobulin level increased to 1,437 ng/ml (normal range: 0-52 ng/ml) after 10 months. Radioiodine scintigraphy and abdominal computed tomography revealed liver metastasis and peritoneal seeding. She underwent debulking surgery of the liver, right salpinx, and peritoneal seeding nodules. A pathological examination showed metastatic follicular carcinoma with focal poorly differentiated features. Adjuvant RAI therapy was restarted, and her serum thyroglobulin levels returned to normal. In conclusion, metastatic lesions were successfully treated with a combination of debulking surgery and RAI therapy. Close medical follow-up monitoring serum thyroglobulin levels is mandatory in such patients.
