RESUMO
OBJECTIVE: Females with low-risk endometrial cancer typically have low lymph node metastasis risk and promising prognosis without lymphadenectomy. However, the impact of grade 3 endometrial cancer on nodal involvement, recurrence, and prognosis within this specific subgroup remains unclear. Therefore, in this study, we aimed to investigate the prognosis, patterns of metastasis, and recurrence in a subgroup of females with grade 3 early-stage low-risk endometrioid endometrial cancer. METHODS: We identified patients from the endometrial cancer cohorts of seven institutional hospitals. The study included patients who underwent hysterectomy between January 2013 and December 2021 with preoperative endometrioid histological type, less than half myometrial invasion, no tumor spread outside the corpus on imaging, normal CA-125 level, and histological grade 3. The clinicopathological characteristics and survival outcomes of the patients were collected. Recurrence-free survival was estimated using the Kaplan-Meier method and compared using the log rank test. RESULTS: Overall, 36 patients were included in this analysis. Of the 33 patients who underwent lymphadenectomy, 1 (1/33, 3.0 %) had lymph node metastasis and 27 (75.0 %) received adjuvant therapy. At a median follow-up of 58 months, three females (8 %) had recurrence and all cases involved lymph nodes. The 5-year recurrence-free survival was 88.7 %. No significant difference was observed in the recurrence-free survival between females who did and did not undergo lymphadenectomy (p = 0.554). CONCLUSION: Females diagnosed with low-risk grade 3 endometrial cancer typically have favorable prognosis. However, lymph node metastasis and recurrence risks still exist, with all recorded instances of recurrence involving lymph nodes.
RESUMO
OBJECTIVE: To identify the effects of subcutaneous drain insertion on wound dehiscence and infection in patients who underwent gynecological midline laparotomy. METHODS: This analysis identified the secondary endpoints of the KGOG 4001 study, a prospective, multicenter, non-blind, randomized controlled trial. Patients scheduled to undergo midline laparotomy for gynecological diseases and, with body mass index<35 kg/m2, were randomized (1:1) to treatment (with subcutaneous drain) and control (without subcutaneous drain) groups from February 2021 to December 2021. We compared the incidence rate of wound dehiscence 4 weeks post-surgery and the cumulative incidence rate of wound dehiscence and infection up to 4 weeks post-surgery between the two groups. RESULTS: Of 174 patients randomized to the treatment (n = 84) and control (n = 90) groups, 12 were excluded owing to loss to follow-up; finally, 162 patients (treatment, n = 79; control, n = 83) were included in intention-to-treat analysis. The frequency of cancer surgery (79.7 % vs. 77.1 %, p = 0.683), mean surgery time (227.7 vs. 226.7 min, p = 0.960), and mean wound length (24.2 vs. 24.3 cm, p = 0.933) were comparable between two groups. No significant differences were observed in the incidence rate of wound dehiscence 4 weeks post-surgery (1.3 % vs. 2.4 %, p > 0.999), cumulative incidence rate of wound dehiscence (8.9 % vs. 6.0 %, p = 0.491), and cumulative incidence rate of wound infection (1.3 % vs. 0.0 %, p = 0.488) up to 4 weeks post-surgery between the two groups. CONCLUSION: Subcutaneous drain insertion is not associated with a significant improvement in the incidence of wound dehiscence and infection in patients who undergo gynecological midline laparotomy.

RESUMO
BACKGROUND: Bulky or multiple lymph node (LN) metastases are associated with poor prognosis in cervical cancer, and the size or number of LN metastases is not yet reflected in the staging system and therapeutic strategy. Although the therapeutic effects of surgical resection of bulky LNs before standard treatment have been reported in several retrospective studies, well-planned randomized clinical studies are lacking. Therefore, the aim of the Korean Gynecologic Oncology Group (KGOG) 1047/DEBULK trial is to investigate whether the debulking surgery of bulky or multiple LNs prior to concurrent chemoradiation therapy (CCRT) improves the survival rate of patients with cervical cancer IIICr diagnosed by imaging tests. METHODS: The KGOG 1047/DEBULK trial is a phase III, multicenter, randomized clinical trial involving patients with bulky or multiple LN metastases in cervical cancer IIICr. This study will include patients with a short-axis diameter of a pelvic or para-aortic LN ≥2 cm or ≥3 LNs with a short-axis diameter ≥1 cm and for whom CCRT is planned. The treatment arms will be randomly allocated in a 1:1 ratio to either receive CCRT (control arm) or undergo surgical debulking of bulky or multiple LNs before CCRT (experimental arm). CCRT consists of extended-field external beam radiotherapy/pelvic radiotherapy, brachytherapy and LN boost, and weekly chemotherapy with cisplatin (40 mg/m²), 4-6 times administered intravenously. The primary endpoint will be 3-year progression-free survival rate. The secondary endpoints will be 3-year overall survival rate, treatment-related complications, and accuracy of radiological diagnosis of bulky or multiple LNs. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05421650; Clinical Research Information Service Identifier: KCT0007137.
RESUMO
OBJECTIVE: The optimal adjuvant treatment for patients with locally advanced endometrial cancer (EC) remains debatable. We comparatively analyzed recurrence patterns and survival outcomes in patients with stage III-IVA EC treated with adjuvant chemotherapy (CT) exclusively or combined with radiotherapy (CRT). METHODS: We retrospectively analyzed 184 patients treated for stage III-IVA EC at 2 tertiary institutions between 2010 and 2021. All patients underwent standard primary surgery and received either CT alone (n = 89) or CRT (n = 95) as an adjuvant treatment. We compared the failure patterns, recurrence-free survival (RFS), and overall survival (OS) between the CT and CRT groups. RESULTS: The median follow-up period was 54.8 months. Most patients underwent pelvic (94.6%) or para-aortic (75.5%) lymphadenectomies. The 5-year RFS was 69.2% with CRT versus 56.3% with CT (P = 0.038), and 5-year OS was 86.1% versus 78.9% (P = 0.357). Pelvic and para-aortic recurrence rates were significantly higher in the CT group (pelvic: 29.2%; para-aortic: 20.2%) than in the CRT group (pelvic: 10.5%; para-aortic: 6.3%). The CRT group showed a higher rate of distant recurrence (CRT, 23.2% vs. CT, 14.6%) however, the 5-year cumulative incidence of distant recurrence was not significantly different between the two groups (CRT, 28% vs. CT, 35%). CONCLUSIONS: This study highlights the potential benefits of adjuvant CRT in patients with stage III-IVA EC. The incorporation of molecular classification is necessary to derive optimal personalized adjuvant treatment strategies for this patient population.

We evaluated the clinical outcomes of using type 1 collagen gel after therapeutic resectoscopy; overall, 150 women aged > 20 who planned to undergo therapeutic resectoscopy were enrolled. The patients were randomly assigned to either of the anti-adhesive treatment groups: the type 1 collagen gel (Collabarrier®) (study group; N = 75) or the sodium hyaluronate and sodium carboxymethylcellulose gel group (control group; N = 75) after resectoscopy. One month after applying anti-adhesive materials, postoperative intrauterine adhesions were evaluated using second-look hysteroscopy; the incidence rate of postoperative intrauterine adhesions examined through second-look hysteroscopy showed no significant differences between the groups. There were no statistical differences between the frequency and mean scores of the type and intensity of adhesions in both groups. Finally, no significant differences in adverse events, serious adverse events, adverse device effects, and serious adverse device effects were noted between the two groups; type 1 collagen gel can be effectively and safely used in intrauterine surgery to minimize postoperative adhesions, thereby eventually decreasing the prevalence of infertility, secondary amenorrhea, and recurrent pregnancy loss in reproductive women.
RESUMO
AIM: Loop electrosurgical excisional procedure (LEEP) is a major treatment method for cervical precancerous lesions. However, recurrence rates were estimated to be 15%, and the risk is increased if a surgical margin is involved by dysplastic cells. This study aimed to identify the risk factors for recurrence of cervical precancerous lesions in patients with positive margins. METHODS: We retrospectively reviewed medical records of patients who underwent LEEP between 2012 and 2014 and had a positive surgical margin. Clinicopathologic factors were collected, including age, parity, menopausal status, smoking, human papilloma virus infection, results of cytology/biopsy/LEEP, and specimen size and volume. RESULTS: A total of 117 patients with positive margins were included, and 26 (22.2%) patients had recurrence. According to a multivariate analysis, the recurrence rates were significantly higher in parous women (adjusted hazard ratio [HR], 2.92; 95% confidence interval [CI], 1.00-8.49), but positive margins at the exocervix (adjusted HR, 0.39; 95% CI, 0.17-0.91) and volume ≥4000 mm3 (adjusted HR, 0.36; 95% CI, 0.16-0.82) showed negative correlation. CONCLUSIONS: The risk of recurrence for cervical precancerous lesions increased in patients with a history of previous delivery, positive margin at the endocervix, and specimen volume of LEEP <4000 mm3 . These results could help gynecologists determine optimal treatment options for patients with positive margins.

The sociomedical environment is changing. In the traditional physician-patient relationship, the physician was authoritative and the patient was obedient. The contractual relationship featured patient consent to the physician's decision. Today, the physician must explain fully the planned medical treatment, and any alternative, to the patient, who has the right to choose her treatment after considering the benefits and side-effects. The Korean Society of Gynecologic Oncology (KSGO) thus decided to standardize the surgical consent forms to meet the legal requirements of modern medicine, improve patient understanding of the surgical details, and protect medical staff from legal disputes. To determine the format and content, subcommittees for each cancer type collected and reviewed all relevant articles and the current consent forms of domestic medical institutions. After several meetings, 16 basic items to be included for each type of gynecologic cancer were selected. Also, to help patients understand the surgical details, figures were included. The revised forms were legally reviewed in terms of the appropriateness of the format and content. We also developed English versions to provide adequate information for foreign patients. We hope that these efforts will promote trust between patients and physicians, and contribute to effective treatment by laying a foundation of mutual respect.

RESUMO
AIM: The aim of this study was to identify subsets of patients diagnosed with nonatypical endometrial hyperplasia (NAEH) by endometrial biopsy who had high risk for occult atypical endometrial hyperplasia (AEH) or endometrial cancer (EC). METHODS: We retrospectively reviewed the medical records of 281 patients who underwent hysterectomy within 6 months after a diagnosis of NAEH. We collected data on age, body mass index, menopausal status, tamoxifen use, previous history of NAEH, details of endometrial biopsy (location, curettage vs. pipelle sampling), NAEH subtype (simple vs. complex), interval between endometrial biopsy and hysterectomy, indication of hysterectomy and the presence of occult AEH or EC in hysterectomy specimen. Associations between variables and occult AEH or EC were analyzed. Risk of occult AEH or EC in subsets were calculated and visualized using a heatmap. RESULTS: Among 281 patients, 34 (12.1%) and 9 (3.2%) had occult AEH and EC in hysterectomy specimens, respectively. Using univariate analysis, we found age, menopausal status and subtype were associated with occult AEH or EC. Using multivariate analysis, older age (odds ratio = 1.09, P < 0.01) and complex subtype (odds ratio = 3.34, P < 0.01) were independent risk factors. Patients at an age ≥ 51 years with complex NAEH had about 50% risk of occult AEH or EC. CONCLUSION: Women at an age ≥ 51 years with complex NAEH had high risk for occult AEH or EC and surgical treatment can be considered for these patients.
RESUMO
For patients with recurrent ovarian cancer, the goals of chemotherapy include palliation of disease-related symptoms with minimum treatment-related side effects. However, there is currently a paucity of data regarding the initiation of palliative chemotherapy. This study aimed to compare the differences in survival rates and toxicities between patients with recurrent ovarian cancer who started palliative chemotherapy immediately versus those who received delayed chemotherapy. Through a retrospective chart review, patients who received more than three lines of chemotherapy were included. Based on the timing of third-line chemotherapy initiation, the patients were divided into two groups: delayed (DTG) and immediate (ITG) treatment groups. The chi-square test or Fisher's exact tests, and t-test or Mann-Whitney U test were used for comparing variables, as appropriate. The Kaplan-Meier method was used for survival analysis. P-value of <0.05 was considered significant. Although there was no statistically significant difference, the total number of regimens and cycles was lower in the DTG than in the ITG. No differences in toxicities and survival rates were observed between the two groups. Overall, survival and toxicity did not differ significantly between the two groups. In a palliative care setting, our findings suggest that delaying the treatment had no adverse effect on survival. Despite the lack of evidence of a survival benefit with aggressive treatment, patients chose to continue chemotherapy. Because recurrent ovarian cancer is a complex condition, patients require sufficient explanation and time to fully understand the costs and benefits related to aggressive chemotherapy.

BACKGROUND: This study assessed the effects of gonadotropin-releasing hormone agonists (GnRHa) on the prevention of chemotherapy-induced ovarian insufficiency among young patients with malignant ovarian germ cell tumour (MOGCT) receiving chemotherapy. METHODS: This multicentre, retrospective study was conducted at 15 sites affiliated with the Korean Gynecologic Oncology Group and enrolled 354 patients between January 1995 and September 2018. Among them, 227 patients were included in this study and divided into two groups according to the use of GnRHa during chemotherapy (GnRHa versus no GnRHa groups). The primary objective was to compare the rates of menstrual resumption between the two groups. We also assessed the clinical determinants affecting menstrual resumption among the study groups. RESULTS: There were no significant differences between the GnRHa (n = 63) and no GnRHa (n = 164) groups regarding age at diagnosis, parity, ethnicity, age at menarche, body mass index, International Federation of Gynecology and Obstetrics stage, mode of surgery and surgery type. The rate of menstrual resumption after chemotherapy was 100% (63 of 63) in the GnRHa group and 90.9% (149 of 164) in the no GnRHa group (p = 0.013). The mean periods from last chemotherapy to menstrual resumption were 7.4 and 7.3 months in the GnRHa and no GnRHa groups, respectively. GnRHa co-administration during chemotherapy reduced the likelihood of amenorrhoea after chemotherapy, although statistical significance was not confirmed in the univariate analysis (odds ratio: 0.276; 95% confidence interval, 0.004-1.317; p = 0.077). CONCLUSION: Temporary ovarian suppression with GnRHa during chemotherapy does not significantly increase the chances of menstrual resumption in young patients with MOGCT.

PURPOSE: To evaluate the effectiveness of bevacizumab with single-agent chemotherapy for platinum-resistant ovarian cancer in a real-world setting. PATIENTS AND METHODS: We enrolled recurrent platinum-resistant ovarian cancer patients from 27 institutions. All had received bevacizumab with single-agent chemotherapy (weekly paclitaxel, pegylated liposomal doxorubicin (PLD), topotecan) between 2015 and 2017 for second- or third-line chemotherapy in routine clinical practice. The primary endpoint was progression-free survival (PFS) and safety. Secondary endpoints included the objective response rate (ORR), PFS2, overall survival, duration of chemotherapy, and reasons for discontinuing chemotherapy. RESULTS: Of 391 patients, 259 (66.2%) received bevacizumab with PLD, 94 (24.0%) with topotecan, and 38 (9.7%) with weekly paclitaxel. The median PFS was 6.1â¯months with all forms of bevacizumab-containing therapy. Although the cohort with weekly paclitaxel had a better PFS than the PLD cohort (Pâ¯=â¯0.028), this finding was not found in patients with a previous platinum-free interval of less than three months. The median duration of therapy was five cycles (range, one to 20â¯cycles), and 29 patients (7.4%) discontinued treatment because of adverse events from bevacizumab-containing regimens. The PLD cohort had fewer gradeâ¯≥â¯3 adverse events than the other regimens (PLD, 35.8%; weekly paclitaxel, 52.6%; topotecan, 51.1%; Pâ¯=â¯0.012), especially events of hematologic toxicities. CONCLUSION: In Korean ovarian cancer patients, the safety and effectiveness of chemotherapy with bevacizumab in a real-world setting was consistent with the results from a randomized controlled study. The effectiveness and toxicity profiles varied among the chemotherapy regimens, and this finding should be considered in practice. CLINICAL TRIALS REGISTRATION: NCT03367182.

OBJECTIVE: Gynecologic oncologists are uncertain about the safety of tibolone application in cervical adenocarcinoma (AC) patients. This study examined the possible adverse effects of tibolone on the survival of cervical AC patients. METHODS: Medical records of 70 cervical AC patients with International Federation of Gynecology and Obstetrics stages IA to IB were reviewed. A bilateral salpingo-oophorectomy was performed in all patients, and survival outcomes between tibolone users (n=38) and non-users (n=32) were compared. RESULTS: A comparison of the tibolone users with non-users revealed similar clinicopathological variables. Progression-free survival (P=0.34) and overall survival (P=0.22) were similar in the users and non-users. The risks of progression (hazard ratio [HR], 1.71; 95% confidence interval [CI], 0.46-6.37; P=0.43) and death (HR, 1.59; 95% CI, 0.06-45.66; P=0.79) were also similar in both groups. CONCLUSION: Tibolone has no adverse effect on the survival of cervical AC patients and can be administered safely to this population. These findings may be helpful in improving the quality of life of cervical AC patients.
RESUMO
OBJECTIVE: To determine whether drospirenone/estradiol (DRSP/E2) has an adverse effect on clinical outcomes in surgically staged International Federation of Gynecology and Obstetrics (FIGO) stage I/II endometrial cancer (EC) patients. METHODS: In a retrospective case-controlled study, 58 women with EC who had received DRSP/E2 postoperatively were compared with 116 women who had not. And, oncologic safety of postoperative hormone therapy with DRSP/E2 in EC survivors were compared between the 2 groups after propensity score matching using a logistic regression model. RESULTS: The median ages were 47.7 years and 53.6 years for the study and the control groups, respectively (p<0.001). The study group had similar parity (p=0.71), lower body mass index (p=0.03) and more premenopausal women (p<0.001) than the control group. The stages were completely matched. The grades (p=0.42), lymphovascular space invasion (p=0.23), preoperative cancer antigen 125 (CA 125) level (p=0.89), and hormone receptor status (p=0.07) were similar in both groups. The median tumor diameter was statistically larger in the study group than in the control group (p<0.001). Both group received similar adjuvant therapy (p=0.80). In the propensity matching, only hormone receptor status was significantly different (p=0.03). In the univariate analysis, only stage was significantly associated with disease-free survival (DFS) and there was no variable associated with overall survival (OS). And, there was no significant factor identified in multivariate analysis. The difference in the DFS (p=0.63) and in the OS (p=0.32) was not significant. The same results were obtained after propensity score matching. CONCLUSION: Postoperative hormone therapy with DRSP/E2 in EC survivors did not increase recurrence or the death rate.

OBJECTIVE: To estimate the effect of adjuvant chemotherapy (AC) on the prognosis in cervical cancer patients with intermediate- or high-risk factors after radical hysterectomy (RH) compared to that for adjuvant radiotherapy (AR). METHODS: The Embase and MEDLINE databases and the Cochrane Library were searched for published studies comparing cervical cancer patients who received AC with those who received AR after RH. The endpoints were patient oncologic outcome. Random-effects meta-analytical models were used to calculate the pooled estimates of the effect of AC on mortality/recurrence. RESULTS: Two randomized trials and eleven observational studies (AC, 942 patients; AR, 1,721 patients) met our search criteria. There were no significant differences in mortality and any recurrence between two groups. The results for distant recurrence favored the AC group (pooled odds ratio: 0.69; 95% confidence interval: 0.54-0.88; p=0.03). In subgroup analyses (for study design, histology, indication for adjuvant treatment, AR type, AC type, and lymph node metastasis), there was no significant increase in mortality and recurrence for AC compared with that for AR. CONCLUSION: Compared to AR, AC showed similar survival outcomes in cervical cancer patients undergoing RH and also appeared to reduce the risk of distant recurrence.

OBJECTIVE: This study aims to analyze the published literatures on the effect of less radical fertility-preserving procedures, such as conization or simple trachelectomy, on oncological outcomes in IA1 cervical cancer patients with lymphovascular space invasion (LVSI) through a systematic-review. METHODS: The EMBASE and MEDLINE databases and Cochrane Library were searched for published studies reporting the oncological outcomes of conization/simple trachelectomy in these patients, through April 2017. The endpoints were recurrence and mortality rates. Data were presented as per the Meta-analysis Of Observational Studies in Epidemiology checklist. Practice guidelines were generated via the Grading of Recommendation, Assessment, Development and Evaluation system. RESULTS: From 6,755 records, 94 full-texts articles were reviewed for eligibility, and five studies were included in this systematic review. All included studies were nonrandomized studies: two case-control studies comparing conization (n = 14) with hysterectomy (n = 24), and the other three were interrupted time series including conization (n = 20) and simple vaginal trachelectomy (n = 59). During the median follow-up duration of 43 months, no recurrence was reported in both conization and simple trachelectomy groups in IA1 patients with LVSI. From three studies reporting the fertility outcomes, the rates of pregnancy, live birth, preterm delivery, and second-trimester miscarriage were 73% (35/48), 64% (32/50), 10% (5/48), and 6% (3/48), respectively. CONCLUSION: Results suggest that simple trachelectomy or conization could be performed for IA1 cervical cancer patients with LVSI who want to preserve fertility, although these results are only based on a small number of nonrandomized studies (recommendation grade 2 = weak; evidence level D = very low). Further randomized trials with long-term study period are needed to address this issue.

OBJECTIVE: To detect the possible clinicopathologic factors associated with parametrial involvement in patients with stage IB1 cervical cancer and to identify a cohort of patients who may benefit from less radical surgery. METHODS: We retrospectively reviewed 120 patients who underwent radical hysterectomy and pelvic lymphadenectomy as treatment for stage IB1 cervical cancer. RESULTS: Overall, 18 (15.0%) patients had parametrial tumor involvement. Tumor size larger than 2 cm, invasion depth greater than 1 cm, presence of lymphovascular space involvement (LVSI), corpus involvement, and positive lymph nodes were statistically associated with parametrial involvement. Multivariate analysis for other factors showed invasion depth >1 cm (P=0.029), and corpus involvement (P=0.022) were significantly associated with parametrial involvement. A subgroup with tumor size smaller than 2 cm showed no parametrial involvement, regardless of invasion depth or presence of LVSI. CONCLUSION: Tumor size smaller than 2 cm showed no parametrial involvement, regardless of invasion depth or presence of LVSI. Invasion depth >1 cm and corpus involvement were significantly associated with parametrial involvement in multivariate analysis. These finding may suggest that tumor size may a strong predictor of parametrial involvement in International Federation of Gynecology and Obstetrics stage IB1 cervical cancer, which can be used to select a subgroup population for less radical surgery.
RESUMO
OBJECTIVE: To evaluate the oncologic outcomes of adjuvant chemotherapy (CT) alone after radical surgery. METHODS: We retrospectively reviewed the medical records of patients who underwent type C radical hysterectomy and pelvic lymphadenectomy with or without paraaortic lymphadenectomy for stage IB-IIA cervical cancer from March 2006 to December 2014 at 2 academic medical centers in Korea. Adjuvant CT alone for patients who met the Sedlis criteria or had lymph node (LN) involvement. Chemotherapeutic regimens consisted of either platinum alone or platinum-based combination. RESULTS: A total of 101 consecutive patients were included in the analysis. The median age was 46.0 years (range, 23-73). Seventy-four patients (73.3%) were clinically staged as IB1; 23 and 4 patients as IB2 and IIA, respectively. The median number of retrieved pelvic and paraaortic LNs (PALNs) were 55.0 (range, 16-101) and 10.0 (range, 2-30), respectively. LN involvement was observed in 25 patients (24.8%). After the median follow-up of 65 months, 14 patients (13.9%) developed disease recurrence. In all patients, the estimated 3-year disease-free survival (DFS) rate and 5-year overall survival (OS) rate were 90.7% and 90.6%, respectively. In patients who met the Sedlis criteria, the 3-year DFS and 5-year OS rates were 94.6% and 90.6%, respectively. Patients with LN metastasis showed a 3-year DFS rate of 79.4% and a 5-year OS rate of 90.6%. CONCLUSION: Adjuvant CT alone could be reasonable option for patients with surgical-pathologic risk factors after radical surgery in stage IB-IIA cervical cancer.
