East Asian Gynecologic Oncology Trial Group (EAGOT): founding history and future perspective / 부인종양

Racial and regional differences exist in morbidity, histology, drug response, toxicity, and prognosis of gynecologic cancer. However, most large-scale phase III studies have been conducted in Western countries, and these data on Asians, who account for more than half of the world’s population, are limited. To build a global clinical trial network in Asia, four clinical trial groups with high expertise and international competitiveness in East Asia, namely the Japanese Gynecologic Oncology Group in Japan, the Korean Gynecologic Oncology Group in Korea, the Taiwanese Gynecologic Oncology Group in Taiwan, and the Chinese Gynecologic Cancer Society in the People’s Republic of China, established a new group called the East Asia Gynecologic Oncology Trial Group (EAGOT) on November 19, 2021. It includes four committees: the Cervical Cancer Committee, Uterine Corpus Cancer Committee, Ovarian Cancer Committee, and Translational Research Committee. The purpose of EAGOT is to conduct international clinical trials in an effort to provide the best treatments for Asian women affected by gynecologic cancer. Discussions on new collaborative clinical trials have already begun. The first Annual EAGOT Meeting was held on May 25-27, 2023 in Niigata, Japan. EAGOT, the largest healthcare/investigational innovation network in Asia in the area of gynecologic cancers, will become a platform for establishing standards of care and lead to guidelines for Asian women suffering from gynecologic cancer. The harmonization of regulatory/investigator-initiated clinical trials, simultaneous approval of unapproved drugs in the four countries under a common protocol, and expansion of indications will improve the prognosis of gynecologic cancers in Asia in the near future.

Real-world outcomes of niraparib treatment in patients with ovarian cancer: the first observational multicenter study in China / 부인종양

Objective@#The objective of this study was to present the real-world patients’ portrait, and the results of niraparib treatment in China. @*Methods@#This study included 142 patients treated with niraparib from 8 hospitals in China between December 2018 and September 2021. Patients’ characteristics were summarized. The efficacy and safety in first-line maintenance (1L-M), platinum-sensitive recurrence maintenance (PSR-M), and treatment for ovarian cancer were evaluated. Survival outcomes and the factors influencing progression-free survival (PFS) were estimated. @*Results@#The 93 patients received Niraparib as 1L-M, 31 as PSR-M and 18 as salvage. BRCA status was wild type or unknown in 87.3% of patients. With a median follow-up time of 8.7 months, the median PFS (mPFS) for 1L-M has not yet been reached, and the mPFS for PSR-M and salvage therapy was 10.5 and 5.7 months, respectively. Responses to last chemotherapy and cancer antigen 125 value before taking niraparib were 2 important factors affecting PFS among 1L and PSR patients. The 12.7% (18/142) of patients experienced grade ≥3 hematologic adverse events and 23.2% experienced dose adjustment. It was noteworthy that when the interval of chemotherapy and niraparib <21 days, the incidence of grade ≥3 adverse events increased significantly (p=0.0355). @*Conclusion@#Generally, niraparib was effective and well tolerated, which was consistent with the results of prospective trials. However, in real world, it was more inclined to use niraparib in late-line treatment without genetic testing.

Effect and Molecular Mechanism of MFG-E8 on Sensitivity of Ovarian Cancer SKOV3 Cells to Cisplatin / 肿瘤防治研究

Objective To investigate the effect of silencing MFG-E8 gene on the sensitivity of SKOV3 cells to anticancer drugs and related mechanisms. Methods SKOV3 cells were transfected with MFG-E8 siRNA (Msi) and NC siRNA (Csi), respectively and the efficiency of transfection was confirmed by Western blot. The sensitivity of SKOV3 cells to cisplatin was observed by CCK-8 assay after transfection. The mRNA expression of ABCB1 and ABCC1 were detected by qRT-PCR. Effect of silencing MFG-E8 on the expression of ETM-related protein was detected by qRT-PCR and Western blot. Results MFG-E8 siRNA could effectively silence the expression of MFG-E8 protein. With the increasing drug concentration, the proliferation inhibition rate of each group also increased, and the cell proliferation inhibition rate of MFG-E8 siRNA group increased significantly (P < 0.01). Compared with NC siRNA group, downregulation of MFG-E8 expression led to decreased SKOV3 cell proliferation at 48h or 72h after 3 μg/ml cisplatin treat ment (P < 0.05). qRT-PCR results showed that the mRNA expression of ABCB1 and ABCC1 in Msi group were significantly lower than those in Csi group. qRT-PCR and Western blot results showed that silencing MFG-E8 gene down-regulated the mRNA and protein expression of N-Cadherin, Vimentin and Snail and up-regulated the expression of E-Cadherin. Conclusion Silencing the MFG-E8 gene can increase the sensitivity of SKOV3 cells against anti-tumor drugs and down-regulate the mRNA expression of ABCB1 and ABCC1, which may be related to the inhibition of EMT progression.

Preoperative interview mode with Child Life in the management of preschool children′s anxiety / 中国实用护理杂志

Objective:To explore the effect of preoperative visit with Child Life mode in the management of preschool children′s anxiety.Methods:A total of 80 cases of children of pre-school age who were operated from September 2018 to February 2019 were selected by cluster sampling method. The children from September to November 2018 who were given the traditional mode of preoperative visit were set as the control group. Children from December 2018 to February 2019 who were given preoperative visit with Child Life mode were set as the experimental group. The Modified Yale Perioperative Anxiety Scale (m-YPAS) scores, Induction Compliance Checklist (ICC) scores and Pediatric Anesthesia Emergence Delirium (PAED) scores were compared between the two groups at 4 different perioperative time points (6 hours after admission, waiting for surgery, induction of anesthesia, and 6 hours after surgery).Results:Totally three patients were suspended from the study due to surgery. A total of 77 children were studied, 38 in the experimental group and 39 in the control group. The score of m-YPAS in the experimental group was significantly lower than that of the control group(17.57±16.64 vs. 42.04±27.46, t value was 3.85, P<0.01) while waiting for surgery. The score of m-YPAS in the experimental group was significantly lower than control group (31.64±27.95 vs. 62.22±25.13, t value was 4.26, P<0.01) at the anesthesia induction. Compare with the control group, the score of m-YPAS in the experimental group showed no significant difference at both time of 6 hours after admission (18.19±17.83 vs.19.85±17.92, t value was 0.87, P>0.05) and 6 hours after surgery(35.61±15.70 vs. 41.81±17.97, t value was 1.37, P>0.05). Compare with the control group the score of ICC in the experimental group was significantly decreased (1.40±1.39 vs. 3.78±2.60, t value was 4.88, P<0.01) at the anesthesia induction. The score of PEAD in the experimental group and control group, there was no significant difference between the two groups (7.18±2.45 vs. 7.85±3.05, t value was 0.91, P>0.05). Conclusions:Compared with the traditional preoperative visit mode, the preoperative visit mode of Child Life can effectively relieve the anxiety of preschool children undergoing general anesthesia surgery while they are waiting for surgery and during anesthesia induction, and can improve the degree of cooperation during anesthesia induction.

Nuclear Factor I/A Controls A-fiber Nociceptor Development / 神经科学通报·英文版

Noxious mechanical information is transmitted through molecularly distinct nociceptors, with pinprick-evoked sharp sensitivity via A-fiber nociceptors marked by developmental expression of the neuropeptide Y receptor 2 (Npy2r) and von Frey filament-evoked punctate pressure information via unmyelinated C fiber nociceptors marked by MrgprD. However, the molecular programs controlling their development are only beginning to be understood. Here we demonstrate that Npy2r-expressing sensory neurons are in fact divided into two groups, based on transient or persistent Npy2r expression. Npy2r-transient neurons are myelinated, likely including A-fiber nociceptors, whereas Npy2r-persistent ones belong to unmyelinated pruriceptors that co-express Nppb. We then showed that the transcription factors NFIA and Runx1 are necessary for the development of Npy2r-transient A-fiber nociceptors and MrgprD C-fiber nociceptors, respectively. Behaviorally, mice with conditional knockout of Nfia, but not Runx1 showed a marked attenuation of pinprick-evoked nocifensive responses. Our studies therefore identify a transcription factor controlling the development of myelinated nociceptors.

IL6 Receptor Facilitates Adipogenesis Differentiation of Human Mesenchymal Stem Cells through Activating P38 Pathway

Background and Objectives@#Mesenchymal stem cells (MSCs) have the multipotent capacity to differentiate into multiple tissue lineages as well as to self-renew, which is the main origin of adipocytes. IL6/IL6R pathway exerts a significant role in tissue regeneration and cell differentiation. Whereas, the underlying mechanism between IL6/IL6R pathway and MSCs adipogenesis differentiation remains elusive. @*Methods@#MSCs from healthy donors were cultured in adipogenesis differentiation medium for 0∼14 days, during which their adipogenesis differentiation degree was evaluated by Oil Red O staining. The expression of IL6R was detected in MSCs during adipogenesis differentiation. Knockdown and overexpression of IL6R were respectively performed using siRNA and lentivirus to investigate its effect on MSCs adipogenesis differentiation. The adipogenesis marker genes expression and MAPK pathway activation were detected by Western blotting. The role of P38 pathway in the adipogenesis differentiation of MSCs was determined using the specific inhibitor SB203580. @*Results@#The expression of IL6 and IL6R increased during adipogenesis differentiation in MSCs, which were positively correlated with Oil Red O quantification result. Knockdown and overexpression experiments demonstrated a positive correlation between the expressions of IL6R and MSCs adipogenesis differentiation, accompanied by same trend of P38 phosphorylation. Besides, the specific P38 inhibitor SB203580 markedly inhibited the adipogenesis differentiation potential of MSCs. @*Conclusions@#This study reveals IL6R facilitates the adiogenesis differentiation of MSCs via activating P38 pathway.

Role of ovarian tumor stem-like cells sorted from human epithelial ovarian cancer SKOV3 cells in vasculogenic mimicry formation / 南方医科大学学报

OBJECTIVE@#To isolate tumor stem-like cells from human epithelial ovarian cancer SKOV3 cells and explore their role in the formation of vascularization mimicry (VM).@*METHODS@#SKOV3 cells were passaged to the 7th generation by suspension culture in serum-free medium, and the percentages of CD133- and CD117-positive cells in the 1st, 3rd, 5th and 7th generations were analyzed using flow cytometry. The proliferative activity of the cells sorted from the 7th generation SKOV3 cells was assessed with colony formation assay. A three-dimensional cell culture model was established to compare the ability of VM formation between the sorted cells and the parental SKOV3 cells. The expression levels of matrix metalloproteinases-2 (MMP-2) and MMP-9 in the two groups were detected using real-time PCR and Western blotting.@*RESULTS@#Some SKOV3 cells formed typical cell spheres with suspension growth in serum-free medium and were passaged to the 7th generation. Flow cytometry revealed that the percentage of CD133-positive cells increased with cell passaging. The cloning efficiency of the sorted cells was significantly higher than that of the parental SKOV3 cells (50.33% 5.33%, < 0.001). The VM formation ability of the sorted cells was stronger than that of the parental SKOV3 cells in the three-dimensional cell culture system. RT-PCR and Western blotting showed that the expression levels of MMP-2 and MMP-9 were significantly higher in the 7th passage cells than in the parental cells ( < 0.05).@*CONCLUSIONS@#The sorted cells from SKOV3 cells cultured in serum-free medium exhibit biological properties of tumor stem cells with strong VM formation ability, suggesting their role in VM formation.

A triage strategy in advanced ovarian cancer management based on multiple predictive models for R0 resection: a prospective cohort study / 부인종양

OBJECTIVE: To present the surgical outcomes of advanced epithelial ovarian cancer (AEOC) since the implementation of a personalized approach and to validate multiple predictive models for R0 resection. METHODS: Personalized strategies included: 1) Non-invasive model: preoperative clinico-radiological assessment according to Suidan criteria with a predictive score for all individuals. Patients with a score 0–2 were recommended for primary debulking surgery (PDS, group A), or otherwise were counseled on the choices of PDS, neoadjuvant chemotherapy (NAC, group B) or staging laparoscopy (S-LPS). 2) Minimally invasive model: S-LPS with a predictive index value (PIV) according to Fagotti. Individuals with a PIV < 8 underwent PDS (group C) or otherwise received NAC (group D). Intraoperative assessment (with Eisenkop, peritoneal cancer index [PCI], and Aletti scores) and surgical results were prospectively collected. RESULTS: Between September 2015 and August 2017, 161 pathologically confirmed epithelial ovarian cancer patients were included. A total of 52 (32.3%) patients had a predictive score of 0–2, and 109 (67.7%) patients had a score ≥ 3. Among these individuals, 41 (25.5%) patients received S-LPS. Finally, 110 (68.3%) patients underwent PDS (A+C), and 51 (31.7%) patients received NAC (B+D). The R0 resection rates in PDS and NAC patients were 56.4% and 60.8%, respectively. The area under the curve (AUC) of Suidan criteria was 0.548 for group (A+C). The AUC of Fagotti score was 0.702 for group C. The AUC of Eisenkop, PCI, and Aletti scores were 0.808, 0.797, and 0.524, respectively. CONCLUSION: The Suidan criteria were not effective in these AEOC patients. S-LPS was helpful in decision-making for PDS and should be endorsed in the future.

Prognostic value of programmed death-ligand 1 (PD-L1) expression in ovarian clear cell carcinoma / 부인종양

OBJECTIVE: Programmed death-ligand 1 (PD-L1) was expressed in various tumors and antibodies targeting its receptor programmed cell death-1 (PD-1) are emerging cancer therapeutics. This study was designed to evaluate the expression of PD-L1 and its correlation with clinicopathologic features and clinical outcomes in ovarian clear cell carcinoma (OCCC). METHODS: The PD-L1 expression was measured by tissue-microarray-based immunohistochemistry from 122 eligible patients diagnosed with OCCC. The associations of clinicopathologic features with progression-free survival (PFS) and overall survival (OS) were analyzed by Kaplan-Meier method and multivariate analysis was further performed by Cox regression model. RESULTS: Overall, high PD-L1 expression (PD-L1(high)) was observed in 44.7% (55/123) of OCCC patients, and was strongly associated with advanced stages (p=0.020), positive ascitic fluid (p=0.016), platinum-resistant (PR) disease (p=0.045), and recurrence (p=0.038). Moreover, patients with PD-L1(high) were associated with poorer OS (hazard ratio [HR]=2.877; p=0.001) and PFS (HR=1.843; p=0.021) than those with low PD-L1 expression (PD-L1(low)). In subgroup analysis, PD-L1(high) patients experienced a poorer PFS (HR=1.926; p=0.044) and OS (HR=2.492; p=0.021) than PD-L1(low) cases among advanced stages (III–IV), but this difference was not observed in stage I–II patients. Meanwhile, PD-L1(high) was associated with poorer prognosis than PD-L1(low) in PR patients (OS, HR=2.253; p=0.037; PFS, HR=1.448; p=0.233). Multivariate analysis revealed that PD-L1(high) and advanced stages (III–IV) were adverse independent prognosticators for both PFS (HR(PD-L1)=2.0; p(PD-L1)=0.038; HR(stage)=10.2; p(stage)<0.001) and OS (HR(PD-L1)=3.0; p(PD-L1)=0.011; HR(stage)=14.3; p(stage)<0.001). CONCLUSION: PD-L1(high) might serve as a risk factor for PFS and OS in patients with OCCC. It is possible that immunotherapy targeting PD-L1 pathway could be used in OCCC.

Elevated TRAF4 expression impaired LPS-induced autophagy in mesenchymal stem cells from ankylosing spondylitis patients

Ankylosing spondylitis (AS) is a type of autoimmune disease that predominantly affects the spine and sacroiliac joints. However, the pathogenesis of AS remains unclear. Some evidence indicates that infection with bacteria, especially Gram-negative bacteria, may have an important role in the onset and progression of AS. Recently, many studies have demonstrated that mesenchymal stem cells (MSCs) dysfunction may contribute to the pathogenesis of many rheumatic diseases. We previously demonstrated that MSCs from AS patients exhibited markedly enhanced osteogenic differentiation capacity in vitro under non-inflammatory conditions. However, the properties of MSCs from AS patients in an inflammatory environment have never been explored. Lipopolysaccharide (LPS), a proinflammatory substance derived from the outer membrane of Gram-negative bacteria, can alter the status and function of MSCs. However, whether MSCs from AS patients exhibit abnormal responses to LPS stimulation has not been reported. Autophagy is a lysosome-mediated catabolic process that participates in many physiological and pathological processes. The link between autophagy and AS remains largely unknown. The level of autophagy in ASMSCs after LPS stimulation remains to be addressed. In this study, we demonstrated that although the basal level of autophagy did not differ between MSCs from healthy donors (HDMSCs) and ASMSCs, LPS-induced autophagy was weaker in ASMSCs than in HDMSCs. Specifically, increased TRAF4 expression in ASMSCs impaired LPS-induced autophagy, potentially by inhibiting the phosphorylation of Beclin-1. These data may provide further insight into ASMSC dysfunction and the precise mechanism underlying the pathogenesis of AS.

Clinicopathological characteristics, treatment and outcomes in uterine carcinosarcoma and grade 3 endometrial cancer patients: a comparative study / 부인종양

OBJECTIVE: Uterine carcinosarcoma (UCS) shared the same staging system with endometrial carcinoma in the International Federation of Gynecology and Obstetrics 2009. The aim of the present study was to compare the clinicopathological and prognostic characteristics between UCS and grade 3 endometrioid endometrial carcinoma (G3EC). METHODS: A retrospective analysis of 60 UCS and 115 G3EC patients with initial treatment at the Department of Gynecology in the Fudan University Shanghai Cancer Center between February 2006 and August 2013. Chi-square analysis was used to compare differences between variables. Prognostic factors were determined using univariate/multivariate analysis, and the survival rates were assessed using the Kaplan-Meier method. The Cox regression model was used to assess the independent prognostic factor. RESULTS: UCS had significantly worse overall survival (OS) compared with G3EC. Carcinosarcoma subtype was an independent factor (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.0 to 5.8; p=0.039), stratified based on stage. Compared with G3EC, UCS patients had a greater incidence of ascites fluid (55.0% vs. 15.7%, p<0.001) and adnexal involvement (20.0% vs. 8.7%, p=0.048) and larger median tumor volume (4.6 cm vs. 4.0 cm, p=0.046). Subgroup analysis of the prognostic factors revealed that UCS patients exhibited worse OS than G3EC patients in such specific subgroups as patients at younger ages, with postmenopausal status, without ascites fluid, with early stage diseases, without vagina invasion, without lymph node metastases and receiving adjuvant chemo/radiotherapy. Adjuvant radiotherapy with chemotherapy was predictive of better survival in UCS patients compared with chemotherapy or radiotherapy alone (5-year OS, 71.0% vs. 35.8%, p=0.028). Multivariate Cox regression revealed that tumor mesenchymal component (HR, 4.6; 95% CI, 1.4 to 15.8; p=0.014) was an independent prognostic factor for UCS, whereas advanced stages (HR, 5.9; 95% CI, 1.0 to 33.9; p=0.046) and ascites fluid (HR, 5.1; 95% CI, 1.1 to 22.7; p=0.032) were independently correlated with poor prognosis for G3EC patients. CONCLUSION: The distinctions in both clinicopathological and prognostic characteristics between UCS and G3EC suggest that this subtype should be treated separately from high-risk epithelial endometrial carcinoma.

Advances in diagnosis and treatment of metastatic cervical cancer / 부인종양

Cervical cancer is one of the most common cancers in women worldwide. The outcome of patients with metastatic cervical cancer is poor. We reviewed the relevant literature concerning the treatment and diagnosis of metastatic cervical cancer. There are two types of metastasis related to different treatments and survival rates: hematogenous metastasis and lymphatic metastasis. Patients with hematogenous metastasis have a higher risk of death than those with lymphatic metastasis. In terms of diagnosis, fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) and PET-computed tomography are effective tools for the evaluation of distant metastasis. Concurrent chemoradiotherapy and subsequent chemotherapy are well-tolerated and efficient for lymphatic metastasis. As for lung metastasis, chemotherapy and/or surgery are valuable treatments for resistant, recurrent metastatic cervical cancer and chemoradiotherapy may be the optimal choice for stage IVB cervical cancer. Chemotherapy and bone irradiation are promising for bone metastasis. A better survival is achieved with multimodal therapy. Craniotomy or stereotactic radiosurgery is an optimal choice combined with radiotherapy for solitary brain metastases. Chemotherapy and palliative brain radiation may be considered for multiple brain metastases and other organ metastases.
