RESUMO
PURPOSE: This study investigated the clinicopathological features and surgical procedures of adnexal masses with abdominal pain in pediatric and adolescent patients. Our objective was to better define the clinical presentation of adnexal torsion and to distinguish characteristics of those with torsion and those with an alternate diagnosis. METHODS: Retrospective cohort study of 212 pediatric and adolescent patients was performed who admitted for abdominal pain and presenting with an adnexal mass between March 2012 to December 2019.Medical records were reviewed for age at operation, including presentation of symptoms and signs; the levels of tumor markers; imaging examinations; pathologic findings; the size of masses; treatment; and outcome. Data management and descriptive analyses were performed using SPSS 26.0. RESULTS: The median age of the patients was 14.5 ± 3.6 years at the operation. 126 (59.4%, 126/212) patients presented with an abrupt onset of abdominal pain. A total of 82.1% (174/212) of the participants underwent adnexal conservative surgery. 179 (84.5%, 179/212) patients underwent laparoscopic surgery with an average tumor size of 7.7 ± 3.4 cm, while 33 patients ( 15.6%, 33/212) underwent laparotomy. Rupture of mass and ectopic pregnancy accounted for 7.5% (16/212) and 0.9%(2/212), respectively. Torsion was responsible for 36.8% (78/212) of all patients. Among the patients with torsion, the symptom of nausea and vomiting was more common among girls without torsion (P < 0.0001). 88.5% of the girls with torsion had acute onset of abdominal pain, while 92.3% had persistent pain that could not be relieved or occurred repeatedly, which significantly higher than that in the patients without torsion (P < 0.001). 69.2% of patients with torsion had fixed pain sites, compared with 42.2% in patients without torsion (P < 0.001). 88.5% of girls with torsion had an ovarian cyst/mass ≥ 5 cm, compared with 75.0% in girls without torsion (P = 0.038). 66.7% of girls underwent ovary-preserving surgery, compared with 92.2% in patients without torsion. The most common pathologic types were mature teratoma and simple cyst, accounting for 29.4% and 25.6%, respectively. The multivariate analyses confirmed that mass size greater than 5 cm (OR 4.134, 95% CI: 1.349-12.669,P = 0.013), acute onset pain (OR 24.150,95%CI: 8.398-69.444,P = 0.000), persistent or recurrent pain (OR 15.911,95%CI: 6.164-41.075,P = 0.000) were significantly associated with increased risk of torsion. CONCLUSIONS: Torsion which is a relatively rare event in the pediatric population was not an uncommon condition and responsible for more than one third of all pediatric and adolescent patients presented with adnexal masses and abdominal pain. Pain assessment in children and adolescents is important to distinguish characteristics of those with torsion and those with an alternate diagnosis.Thus, pediatric and adolescent patients particularly with a pelvic mass size greater than 5 cm, acute onset pain, persistent or recurrent pain have a benign cause and not missing the devastating condition that needs emergent attention. Thus, a strategy of earlier and liberal use of Diagnostic Laparoscopy (DL) may improve ovarian salvage.

OBJECTIVE: This study aimed to reveal the urinary and serum metabolic pattern of endometrial cancer (EC) and establish diagnostic models to identify EC from controls, high-risk from low-risk EC, and type II from type I EC. METHOD: This study included 146 EC patients (comprising 79 low-risk and 67 high-risk patients, including 124 type I and 22 type II) and 59 controls. The serum and urine samples were analyzed using ultraperformance liquid chromatography mass spectrometry. Analysis was used to elucidate the distinct metabolites and altered metabolic pathways. Receiver operating characteristic (ROC) analyses were employed to discover and validate the potential biomarker models. RESULTS: Serum and urine metabolomes displayed significant differences between EC and controls, with metabolites related to amino acid and nicotinamide metabolisms. The serum and urine panels distinguished these two groups with Area Under the Curve (AUC) of 0.821 and 0.902, respectively. The panel consisting of serum and urine metabolites demonstrated the best predictive ability (AUC = 0.953 and 0.976 in discovering and validation group). In comparing high-risk and low risk EC, differential metabolites were enriched in purine and glutamine metabolism. The AUC values for serum and urine panels were 0.818, and 0.843, respectively. The combined panel exhibited better predictive accuracy (0.881 in discovering group and 0.936 in external validation). In the comparison between type I and type II group, altered folic acid metabolism was identified. The serum, urine and combined panels discriminated these two groups with the AUC of 0.829, 0.913 and 0.922, respectively. CONCLUSION: The combined urine and serum metabolome effectively revealed the metabolic patterns in EC patients, offering valuable diagnostic models for EC diagnosis and classification.

BACKGROUND: Falls pose a significant health risk in older adults, with stair descent falls carrying particularly severe consequences. Reduced balance control and limb support due to aging-related physiological and neuromuscular decline are critical components in increased falling risk in older adults. Understanding the age-associated abnormalities in balance control and limb support strategies during sudden forward and downward body shift could reveal potential biomechanical deficits responsible for increased falling risks in older adults. This study investigates balance regulatory responses following first-time exposure to compelled forward and downward body shift in young and older adults. METHODS: Thirteen healthy old and thirteen healthy young adults participated in this study. Participants stood on two adjacent perturbation platforms in modified tandem stance. The leading limb support surface dropped 3 in. vertically at an unknown time. The anterior margin of stability and center of mass velocity, peak vertical ground reaction forces, and leading limb ankle and knee joint angular displacement, torque, and power during the initial response phase were compared between age groups. FINDINGS: Compared to young adults, older adults showed higher center of mass velocity, lower margin of stability, peak vertical ground reaction force, peak ankle and knee joint power, and peak knee joint torque during the initial response phase. INTERPRETATIONS: The abnormalities potentially identified in our study, particularly in dynamic stability regulation, limb support force generation, and shock absorption may affect the ability to arrest the body's forward and downward motion. These deficits may contribute to an increased risk of forward falls in aging.

After stroke, deficits in paretic single limb stance (SLS) are commonly observed and affect walking performance. During SLS, the hip abductor musculature is critical in providing vertical support and regulating balance. Although disrupted paretic hip abduction torque production has been identified in individuals post-stroke, interpretation of previous results is limited due to the discrepancies in weight-bearing conditions. Using a novel perturbation-based assessment that could induce SLS by removing the support surface underneath one limb, we aim to investigate whether deficits in hip abduction torque production, vertical body support, and balance regulation remain detectable during SLS when controlling for weight-bearing, and whether these measures are associated with gait performance. Our results showed that during the perturbation-induced SLS, individuals post-stroke had lower hip abduction torque, less vertical stiffness, and increased frontal plane angular impulse at the paretic limb compared to the non-paretic limb, while no differences were found between the paretic limb and healthy controls. In addition, vertical stiffness during perturbation-induced SLS was positively correlated with single support duration during gait at the paretic limb and predicted self-selected and fast walking speeds in individuals post-stroke. The findings indicate that reduced paretic hip abduction torque during SLS likely affects vertical support and balance control. Enhancing SLS hip abduction torque production could be an important rehabilitation target to improve walking function for individuals post-stroke.

BACKGROUND: Falls are major health concerns in older adults. Sit-to-stand transfer is an important functional movement that can predict falling risk in older adults. Aging-associated declines in neuromechanical control of movement may negatively impact sit-to-stand performance. This systematic review aims to summarize differences in neuromechanical characteristics of younger vs. older adults that likely affect balance regulation during sit-to-stand. METHODS: Five databases (Academic search complete, MEDLINE, APA PsycInfo, Pubmed, and SPORTDiscus) were systematically searched from January 1985 through March 2023. Three reviewers assessed the quality of methodology, study design, results, and risk of bias using the Appraisal tool for Cross-Sectional Studies. Studies reported neuromuscular and biomechanical characteristics during sit-to-stand in young versus older adults were included. FINDINGS: Seventeen studies (343 older and 225 younger adults) were included. Compared to younger adults, older adults showed slower sit-to-stand time, higher trunk flexion, postural sway, agonist-antagonist muscle co-activation of the ankle and knee muscles, and lower ankle dorsiflexion torque. Lower magnitude and rate of vertical ground reaction force development and lower vertical momentum during rising were observed with aging during fast-speed sit-to-stand. There was heterogeneity among studies on sit-to-stand speed, foot position, use of arms, and seat height adjustability. INTERPRETATIONS: Higher trunk angular displacement and velocity accompanied by higher anterior momentum, likely to compensate for knee extensor muscle weaknesses, may lead to higher postural sway upon standing and therefore require higher knee and ankle muscle co-activation to maintain balance stability. Thus, additional attention to trunk control strategies is needed during clinical evaluations.

During SLS, the hip abductor musculature is critical in providing vertical support and regulating balance. Although disrupted paretic hip abduction torque production has been identified in individuals post-stroke, interpretation of previous results is limited due to the discrepancies in weight-bearing conditions. Objective: To investigate whether deficits in hip abduction torque production, vertical body support, and balance regulation remain during SLS when controlling for weight-bearing using a perturbation-based assessment, and whether these measures are associated with gait performance. Methods: We compared hip abduction torque, vertical stiffness, and frontal plane angular impulse between individuals post-stroke and healthy controls when SLS was induced by removing the support surface underneath one limb. We also tested for correlations between vertical stiffness and angular impulse during perturbation-induced SLS and gait parameters during overground walking. Results: During the perturbation-induced SLS, lower hip abduction torque, less vertical stiffness, and increased frontal plane angular impulse were observed at the paretic limb compared to the non-paretic limb, while no differences were found between the paretic limb and healthy controls. Vertical stiffness during perturbation-induced SLS was positively correlated with single support duration during gait at the paretic limb and predicted self-selected and fast walking speeds in individuals post-stroke. Conclusions: Reduced paretic hip abduction torque during SLS likely affects vertical support and balance control. Enhancing SLS hip abduction torque production could be an important rehabilitation target to improve walking function for individuals post-stroke.
RESUMO
BACKGROUND: Ovarian cancer is the most lethal gynaecological malignancy. Damage specific DNA-binding protein 1 (DDB1) functions in nucleotide-excision repair and has been reported to be involved in cancer development. In this study, we aimed to determine the expression levels of DDB1 and their association with the clinical outcomes of patients with ovarian cancer. METHODS: Tissue arrays were performed on 54 epithelial ovarian cancer (EOC) samples. Immunohistochemistry was performed to determine DDB1 expression. DDB1 expression levels among different EOC subtypes were analysed via one-way analysis of variance using SPSS Statistics 19.0. Correlation between DDB1 expression and chemotherapy course/progression-free survival (PFS) of patients was determined via Kaplan-Meier survival analysis using GraphPad Prism 5. Moreover, knockdown of DDB1 in ovarian cancer cells ES2 and OVCAR3 was used to preliminarily validate the role of DDB1. RESULTS: DDB1 was detected in the cytoplasm, especially in the nucleus, of all subtypes of EOC. However, DDB1 expression levels were significantly different between clear cell carcinoma and low-grade serous carcinoma (P = 0.022) and clear cell carcinoma and endometrioid cancer (P = 0.016). In addition, DDB1 expression was not significantly correlated with chemotherapy course (P = 0.433) or PFS (P = 0.566). High expression levels of DDB1 were correlated with significantly worse overall survival (P = 0.017) in patients with EOC. In addition, DDB1 knockdown in ovarian cancer cells decreased their proliferation in vitro. CONCLUSION: Our results revealed that DDB1 expression is heterogeneous in ovarian cancer, suggesting its use as a potential biomarker for poor survival in ovarian cancer.

BACKGROUND: To evaluate the oncological outcomes and the impact of clinicopathological factors on endometrial clear cell carcinoma (ECCC) outcomes. METHODS: Medical records of patients with primary ECCC treated at our center between 1985 and December 2020 were reviewed. Overall survival (OS) and progression-free survival (PFS) were the endpoints. The Kaplan-Meier method and Cox regression analysis were used. RESULTS: In total, 156 patients were included, of whom 59% and 41% had early- and advanced-stage ECCC, respectively. The median age of onset was 61 years, and 80.8% of the patients were postmenopausal. Ninety-two (59%) and 64 (41%) patients had pure ECCC and mixed endometrial carcinoma with clear cell carcinoma (CCC) components, respectively. Mixed pathological components, elevated cancer antigen 125 levels, positive lymphovascular space invasion, deep myometrial invasion, and malignant peritoneal washing cytology (PWC) were more frequently observed in the advanced stage. Thirty-nine patients (25%) experienced relapse and 32 patients (20.5%) died. The 5-year PFS and OS rates for the entire cohort were 72.6% and 79%, respectively. Multivariate analysis showed that advanced-stage disease and positive PWC significantly decreased PFS, while advanced-stage disease and older age (> 61 years) significantly decreased OS. CONCLUSIONS: ECCC is a rare and aggressive type II endometrial carcinoma that is common in older women and patients with advanced-stage disease. Positive PWC was associated with decreased PFS, although its presence did not influence the stage. Positive PWC, and advanced stage and older age were independent negative prognostic factors.

Objective: This study aimed to summarize the clinical features, treatment modalities, therapeutic effects, menstruation and fertility outcomes, and prognosis of extragonadal yolk sac tumors (YSTs) of the female genital tract. Methods: We reviewed 32 cases of extragonadal YSTs in the genital tract treated between 1983 and 2021. The medical records, including clinical characteristics, histopathology, treatments, chemo-reduced adverse events, and outcomes on long-term follow-up, were collected. Results: Among the 32 cases, 30 were vaginal YSTs and two were uterine YSTs (endometrial and cervical). Thirty patients (30/32, 93.8%) were <4 years. Abnormal vaginal bleeding (n = 31) and elevated serum alpha-fetoprotein level (n = 32) were the most common presentations. Vaginohysteroscopy and/or pediatric rhinoscopy were used for diagnosis in 17 pediatric patients and evaluation of chemotherapeutic efficacy in 21 pediatric patients. All the patients received combination chemotherapy. Bleomycin/etoposide/cisplatin (BEP) was chosen with prior consideration in 28 cases; 21 patients were treated with BEP alone. Yellow or grayish-yellow tissue with irregular shape was found in 66.7% of the cases during repeat examinations. Five patients underwent surgeries during repeat examinations and follow-ups, and no evidence of malignancy was noted in them. Thirty-one patients achieved complete remission. During a median follow-up of 63 months (2.4-240.3 months), two patients experienced recurrence, three died, and 29 remained disease-free. One patient recovered menstruation and five had undergone menarche. Conclusion: BEP chemotherapy can serve as a preferred treatment modality for vaginal and uterine YSTs. Vaginohysteroscopy and pediatric rhinoscopy can be used for diagnosis and evaluation of chemotherapeutic efficacy in pediatric patients. YSTs possibly appear as yellow or grayish-yellow after chemotherapy.
RESUMO
Decreased loading of the paretic lower limb and impaired weight transfer between limbs negatively impact balance control and forward progression during gait in individuals post-stroke. However, the biomechanical and neuromuscular control mechanisms underlying such impaired limb loading remain unclear, partly due to their tendency of avoiding bearing weight on the paretic limb during voluntary movement. Thus, an approach that forces individuals to more fully and rapidly load the paretic limb has been developed. The primary purpose of this study was to compare the neuromechanical responses at the ankle and knee during externally induced limb loading in people with chronic stroke versus able-bodied controls, and determine whether energy absorption capacity, measured during induced limb loading of the paretic limb, was associated with walking characteristics in individuals post-stroke. Results revealed reduced rate of energy absorption and dorsiflexion velocity at the ankle joint during induced limb loading in both the paretic and non-paretic side in individuals post-stroke compared to healthy controls. The co-contraction index was higher in the paretic ankle and knee joints compared to the non-paretic side. In addition, the rate of energy absorption at the paretic ankle joint during the induced limb loading was positively correlated with maximum walking speed and negatively correlated with double limb support duration. These findings demonstrated that deficits in ankle dorsiflexion velocity may limit the mechanical energy absorption capacity of the joint and thereby affect the lower limb loading process during gait following stroke.

OBJECTIVE: To evaluate the efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined with a levonorgestrel-releasing intrauterine device (LNG-IUD) or aromatase inhibitor (letrozole) in women with endometrial carcinoma or atypical endometrial hyperplasia who wished to preserve fertility. METHODS: Patients at the Department of Obstetrics and Gynecology, Peking Union Medical College Hospital between January 2013 and December 2020 were retrospectively reviewed. A total of 179 patients who were unsuitable to undergo treatment with high-dose oral progestin, including those with progestin allergies, body mass index ≥30 kg/m2, liver and/or renal dysfunction, hypercoagulable state, and thrombosis were included. Patient data were retrieved from medical records and a prospectively maintained database that represented the standard protocol was followed for all patients. Clinical characteristics, treatment outcomes, adverse events, and reproductive outcomes were collected and analyzed. Logistic regression models were constructed to determine the associations between complete remission, recurrence, and fertility. RESULTS: Overall, 169 patients (94.4%) achieved complete remission; 58 (96.7%) had atypical endometrial hyperplasia and 111 (93.3%) had endometrial carcinoma. The complete remission rates for the GnRHa plus LNG-IUD and GnRHa plus letrozole groups were 93.5% and 95.8%, respectively. The median time to complete remission was 6 (range 3-18) months: 4 (range 3-10) months for atypical endometrial hyperplasia and 8 (range 3-18) months for endometrial carcinoma. After a median follow-up of 27.5 (range 3-92) months, 41 (24.3%) women developed recurrence, with a median recurrence time of 17 (range 6-77) months. Of the patients with complete remission, 134 patients desired to conceive and 42 (32.3%) became pregnant, 24 (17.9%) were successfully delivered, 5 (3.7%) were still pregnant, while 13 miscarried. CONCLUSION: GnRHa combined treatment provides favorable oncological and reproductive outcomes. Larger multi-institutional studies are required to confirm these preliminary findings.

OBJECTIVES: The aim of the study was to explore the rate of upstaging after complete surgical staging among patients with apparent FIGO stage I ovarian mucinous carcinoma. METHODS: Ovarian mucinous carcinoma patients with surgical treatment at the Peking Union Medical College Hospital between October 2020 and January 1994 were retrospectively reviewed. RESULTS: In total, 163 patients were included in this study. Surgical restaging was performed in 89 patients after initial incomplete surgical staging, and one-step complete surgical staging was performed in 74 patients. Among these initially incompletely staged patients, residual tumors were found in 16 patients (16/89, 17.9%). Among the 19 patients with apparent FIGO stage IA, no patient was found to have residual tumors after incomplete staging surgery, according to the final pathology result of restaging surgery. Ovarian cystectomy (OR=4.932, 95% CI= 1.347-18.058, P=0.016) was an independent risk factor for residual tumors after incomplete staging surgery. Among all 163 patients, upstaging occurred in 15 patients (15/163, 9.2%). Among 44 apparent FIGO stage IA patients, no patient was upstaged to FIGO II-IVB. Moreover, both a history of ovarian mucinous tumor (OR=4.745, 95% CI= 1.132-19.886, P=0.033) and bilateral ovary involvement (OR=9.739, 95% CI= 2.016-47.056, P=0.005) were independent risk factors for upstaging to FIGO stage II-IVB. CONCLUSIONS: For patients with apparent FIGO stage IA disease, the possibility of residual tumors and upstaging is relatively low. For patients with cystectomy, bilateral mucinous carcinomas, or a history of ovarian mucinous tumors, complete staging surgery maintains greater significance.

Background: Fertility-sparing surgery (FSS) has been widely used for patients with early-stage mucinous ovarian carcinoma (MOC). However, there is limited evidence regarding the reproductive outcomes as well as the impact of growth pattern on oncological outcomes after FSS. This study aims to evaluate the oncological and reproductive outcomes of patients with stage I primary MOC after FSS. Methods: This retrospective study enrolled 159 women with histologically confirmed unilateral stage I MOC treated at Peking Union Medical College Hospital between 1997 and 2019. Sixty-seven cases were pathologically reviewed for the growth pattern. Seventy-eight patients had FSS, defined as conservation of the uterus and at least part of one ovary, while 81 underwent radical surgery (RS). Oncofertility outcomes were compared between the groups and clinicopathological factors associated with disease-free survival (DFS) were analyzed by univariate and multivariate analyses. Patients in the FSS group were contacted to collect data on reproductive outcomes. Results: Eighteen patients developed recurrent disease during a median follow-up of 69 months, including 12 in the FSS and six in the RS group. There was one death each in the FSS and RS groups. There was no significant difference in DFS between the groups. CA125 >35 U/ml, stage IC, and incomplete staging were correlated with worse DFS according to multivariate analysis (P=0.001; 0.020 (stage IC) and 0.004 (incomplete staging) respectively). There was no significant difference in DFS between patients with stage IA and stage IC1 in the FSS group, while DFS was poorer in patients with stage IC2/3 than stage IA (P=0.028). In addition, DFS was significantly poorer in patients who underwent unilateral salpingo-oophorectomy (USO) compared with those receiving USO plus staging surgery (P=0.015). There was a tendency towards poorer DFS in the infiltrative tumors compared with the expansile tumors (P=0.056). Of 23 patients who attempted to conceive, 21 (91.3%) achieved 27 pregnancies, including 26 spontaneous pregnancies and one following assisted reproductive technology. Twenty patients gave birth to 24 healthy babies, including 21 full-term and three premature births. The live-birth rate was 88.9%. Conclusions: FSS is a suitable option for young women with unilateral stage I expansile MOC, with acceptable oncological outcomes and meaningful pregnancy rates. Re-staging should be proposed in patients who undergo incomplete staging surgery.
RESUMO
Objective To investigate the clinical characteristics of preadolescent and adolescent female patients with ovarian mass combined with dysplasia of secondary sexual characteristics. Methods This study retrospectively analyzed 18 cases of ovarian mass combined with dysplasia of secondary sexual characteristics aged 0-19 years admitted to Peking Union Medical College Hospital from January 2012 to November 2019.By analyzing the clinical manifestations,surgical methods,postoperative pathology,therapies and prognosis of the cases,we summarized the diagnosis and treatment ideas. Results Among the 18 cases,7(7/18,38.9%)developed secondary sex signs before puberty,including 5 cases showing precocity(including 2 cases of juvenile granulosa cell tumor,1 case of gonadoblastoma,1 case of ovarian follicular cyst,and 1 case of 46,XY simple gonadal dysplasia combined with dysgerminoma)and 2 cases presenting masculine manifestations(1 case of steroid cell tumor and 1 case of sclerosing stromal tumor).The rest 11(11/18,61.1%)cases showed abnormal development of secondary sexual characteristics during puberty,including 8 cases with masculine manifestations or abnormal menstruation after menarche(7 cases with sex cord stromal cell tumor and 1 case with cystic granulosa cell tumor),2 cases with primary amenorrhea(1 case with androgen insensitivity syndrome combined with testicular sertoli cell tumor and 1 case with endometriosis cyst combined with reproductive tract malformation),and 1 case diagnosed as 46,XX gonadal dysplasia with serous cystadenoma and no secondary sexual development during puberty. Conclusions Sex hormone levels should be actively tested in the case of prepubertal secondary sexual characteristics appearing early,pubertal secondary sexual characteristics being abnormal(underdevelopment),and/or menstrual abnormalities.Imaging examination should be performed to exclude ovarian organic lesions,and chromosome karyotype analysis should be performed if necessary.The diagnosis of ovarian mass in preadolescent and adolescent females with related symptoms should first be alerted to cord stromal cell tumor.It is recommended to rule out the possibility of combined reproductive tract malformation in the adolescent patients with primary amenorrhea.Chromosome examination should be conducted to rule out the possibility of gonadal dysplasia in the adolescent patients with primary amenorrhea and/or no development of secondary sexual characteristics.

OBJECTIVE: To evaluate the efficacy and prognosis of fertility-sparing treatment on endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) patients with BMI ≥ 30 kg/m2. METHODS: A total of 102 EC or AEH patients with obesity who received fertility-preserving therapy in the Department of Obstetrics and Gynecology, Peking Union Medical College Hospital were included in our study. All patients were followed up regularly. Clinical characteristics, treatment outcomes, adverse events, and reproductive outcomes were collected and analyzed. RESULTS: A total of 88 (86.3%) patients achieved complete response (CR), 92.5% in AEH and 82.3% in EC, with 6 months (3-12 months) median CR time. High remission rates were found in patients who received gonadotropin-releasing hormone agonist (GnRHa)-based regimen, were younger than 35 years old, and lost more than 10% of their weight. Fifteen (17.0%) women had developed recurrence with a median recurrence time of 26 (8-52) months. Patients who received GnRHa regimen, lost more than 10% weight, received maintenance therapy, or conceived during the follow-up period had a low probability of recurrence. Of the patients with CR, 57 women attempted to get pregnant and 16 (28.1%) patients became pregnant, 7 (12.3%) of them successfully delivered and 4 (7.0%) were in pregnancy, while 5 (8.8%) of them miscarried. CONCLUSION: For obese patients with EC and AEH, fertility-preserving treatment can still achieve a promising response. Weight loss of more than 10% has a positive influence on response, recurrence, as well as pregnancy rates. GnRHa could be an option for obese women due to less effect on weight gain compared to progestin therapy.
RESUMO
STUDY OBJECTIVE: The objective of the study was to analyze the oncological outcomes and prognostic factors in patients with early-stage juvenile granulosa cell tumor (JGCT) who underwent fertility-sparing surgery. DESIGN, SETTING, AND PARTICIPANTS: All patients with early-stage JGCT who underwent fertility-sparing surgery between January 1995 and December 2017 were reviewed retrospectively. INTERVENTIONS: None. MAIN OUTCOME MEASURES: The risk factors for recurrence and death in patients with early-stage JGCT were identified. RESULTS: Thirty-five patients were eligible for the current study. The median age was 17 years (range: 4-30 years), and 10 patients were premenarchal. Nine patients were International Federation of Obstetrics and Gynecology stage IA, and 26 were stage IC. Eight subjects underwent complete staging, whereas 28 had no staging at their initial surgery. In those without initial staging, 3 patients who received initial unilateral salpingo-oophorectomy (USO) and 6 with initial cystectomy underwent secondary surgery for staging or USO with staging, respectively. At the time of the secondary staging operation, 1 of the subjects (treated with USO at initial surgery) was found to be stage III and was excluded from this study. Therefore, 8 patients underwent secondary staging surgery performed by laparoscopic surgery, and none of them suffered recurrence during follow-up. Fourteen of the 16 patients with complete staging surgery underwent lymphadenectomy, and none of them had lymph node metastasis. Thirty-one patients received adjuvant chemotherapy after surgery. Eight patients had disease recurrence after a median follow-up time of 51 months (range: 6-229 months), with a median time to recurrence of 4.5 months (range: 2-52 months). Six patients died of their disease. The 5-year disease-free and overall survival rates were 74.8% and 84.3%, respectively. Univariate analysis showed that incomplete staging surgery was associated with increased risk of recurrence (P = 0.029). Adjuvant chemotherapy was not associated with disease-free survival. Four patients had a total of 6 pregnancies, resulting in 6 live births. CONCLUSION: Complete surgical staging is recommended for early-stage JGCT, but lymph node dissection can be omitted. Laparoscopic restaging surgery is feasible for patients with incomplete staging at initial surgery. However, the prognosis of patients with relapsed JGCT remains poor.

BACKGROUND: Cervical tumors usually have an irregular morphology. It is often difficult to estimate tumor size or volume based on a diameter measurement from a two-dimensional magnetic resonance imaging slice. This study aimed to explore the use of magnetic resonance imaging-based three-dimensional reconstruction in cervical cancer. METHODS: We retrospectively created a three-dimensional reconstruction based on the pre-treatment magnetic resonance imaging data of 54 cervical cancer patients at a single center to evaluate tumor size and extent of invasion, as well as to review cervical cancer staging and treatment. The tissues and organs were automatically outlined by the three-dimensional application, based on the signal intensity difference of magnetic resonance imaging data. RESULTS: The maximum tumor diameters calculated using the magnetic resonance imaging-based three-dimensional reconstruction were larger than those calculated from the direct magnetic resonance imaging findings or gynecological examinations. Initial underestimation of the maximum tumor diameter led to under-staging in up to 29.6% of patients. The magnetic resonance imaging-based three-dimensional reconstruction revealed that upstaging was warranted based on lymph node metastasis (3.7% of patients) and invasion of the vaginal fornix (1.9% of patients). Lymph node metastasis was associated with a significantly larger tumor volume (P<0.05). A volume cut-off value ≥18.6 mL provided 60% sensitivity, 96.7% specificity, 75% positive predictive value and 93.5% negative predictive value for predicting high-risk patients (P<0.05). CONCLUSIONS: Magnetic resonance imaging-based three-dimensional reconstruction is a new approach that could potentially measure cervical cancer more accurately.
RESUMO
OBJECTIVE: To evaluate the efficacy and prognosis of fertility-sparing re-treatment on patients with recurrent endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) who wish to preserve their uterus after complete remission (CR) for primary conservative therapy. METHODS: We performed a retrospective study on recurrent EC or AEH patients who received fertility-sparing re-treatment after achieving CR. Data regarding clinicopathological factors, adverse events, treatment efficacy, tumor prognosis, and reproductive outcome were analyzed. RESULTS: Of the 98 recurrent patients with a median disease-free interval period of 19 (3-96) months, 18 patients decided to receive hysterectomy directly, and 80 patients received fertility-preserving re-treatment. Seventy-one (88.6%) cases achieved CR, 96.0% in AEH and 75.8% in EC patients, with the 6 (3-16) months' median CR time. Seven (8.8%) patients failed to achieve CR and then underwent the hysterectomy: one partial response (PR), four stable disease (SD), and two progressive disease (PD). Forty-nine women attempted to get pregnant after CR, 13 (26.5%) became pregnant, seven (14.3%) successfully delivered, and six (12.2%) miscarried. During the follow-up period, 22 (31.0%) women had developed a second relapse with the median recurrence time of 12 (4-90) months, and 10 patients decided to receive the third round of fertility-sparing treatment. Seven (70.0%) patients, 33.3% in EC and 85.7% in AEH, achieved CR again. Hysterectomy was performed in two (20.0%) patients due to SD. After the third-round treatment, six women had the desire to conceive but no one became pregnant successfully. CONCLUSION: For patients with recurrent EC and AEH after primary conservative treatment, fertility-preserving re-treatment can still achieve a promising response, and patients have possibilities of completing childbirth.
RESUMO
BACKGROUND: Though considerable efforts have been made to improve the treatment of epithelial ovarian cancer (EOC), the prognosis of patients has remained poor. Identifying differentially expressed genes (DEGs) involved in EOC progression and exploiting them as novel biomarkers or therapeutic targets is of great value. METHODS: Overlapping DEGs were screened out from three independent gene expression omnibus (GEO) datasets and were subjected to Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analyses. The protein-protein interactions (PPI) network of DEGs was constructed based on the STRING database. The expression of hub genes was validated in GEPIA and GEO. The relationship of hub genes expression with tumor stage and overall survival and progression-free survival of EOC patients was investigated using the cancer genome atlas data. RESULTS: A total of 306 DEGs were identified, including 265 up-regulated and 41 down-regulated. Through PPI network analysis, the top 20 genes were screened out, among which 4 hub genes, which were not researched in depth so far, were selected after literature retrieval, including CDC45, CDCA5, KIF4A, ESPL1. The four genes were up-regulated in EOC tissues compared with normal tissues, but their expression decreased gradually with the continuous progression of EOC. Survival curves illustrated that patients with a lower level of CDCA5 and ESPL1 had better overall survival and progression-free survival statistically. CONCLUSION: Two hub genes, CDCA5 and ESPL1, identified as probably playing tumor-promotive roles, have great potential to be utilized as novel therapeutic targets for EOC treatment.

We evaluated the relationship between the minimum tumor-free margin, tumor volume, and adverse pathological risk factors in early cervical cancer and explored the predictive value of these parameters for different types of risk patients to guide individualized therapeutic strategies. Patients who received the initial treatment of radical operation of cervical cancer and their postoperative pathological reports in our hospital from July 1, 2017, to June 30, 2019, were reviewed. Their minimum tumor-free margin and tumor volume were measured on preoperative magnetic resonance imaging. Student's t-test and the receiver operating characteristic curve analysis were used for data analysis. A total of 240 patients were included. Adverse pathological risk factors were as follows: deep cervical infiltration, 95 (39.6%) cases; lymph vascular space invasion, 91 (37.9%); lymph node metastasis, 20 (8.3%); parametrial infiltration, 8 (3.3%); tumor diameter ≥4 cm, 7 (2.9%); and positive surgical margin, 1 (0.4%). According to the adverse pathological factors, there were 20 (8.3%) high-risk patients, 50 (20.8%) medium-risk patients, and 170 (70.8%) low-risk patients. The ranges of the minimum tumor-free margin and tumor volume were 0.01-13.5 mm and 105-27,990 mm3, respectively. The minimum tumor-free margin with lymph node metastasis was significantly smaller than that without (P <0.05). The tumor volume with parametrial infiltration, deep cervical infiltration, or lymph vascular space invasion was significantly greater than that without (P < 0.05). The tumor volume was significantly different among low-, medium-, and high-risk patients (P <0.05). Tumor volume was of predictive value for high-risk patients (P < 0.05). With 3,505 mm3 as the cutoff value, the sensitivity and specificity for the prediction of high-risk patients were 88.9% and 84.8%, respectively. Tumor volume can be used as a great predictor of high-risk patients (cutoff value, 3,505 mm3), which could be an indication of initial chemoradiotherapy for early cervical cancer.
