[PMID: 38791891 PMCID: PMC11120355 DOI: 10.3390/cancers16101812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 04/30/2024] [Accepted: 05/04/2024] [Indexed: 05/26/2024] Open
Abstract
Ovarian cancer (OC) is an umbrella term for cancerous malignancies affecting the ovaries, yet treatment options for all subtypes are predominantly derived from high-grade serous ovarian cancer, the largest subgroup. The concept of "functional precision medicine" involves gaining personalized insights on therapy choice, based on direct exposure of patient tissues to drugs. This especially holds promise for rare subtypes like low-grade serous ovarian cancer (LGSOC). This study aims to establish an in vivo model for LGSOC using zebrafish embryos, comparing treatment responses previously observed in mouse PDX models, cell lines and 3D tumor models. To address this goal, a well-characterized patient-derived LGSOC cell line with the KRAS mutation c.35 G>T (p.(Gly12Val)) was used. Fluorescently labeled tumor cells were injected into the perivitelline space of 2 days' post-fertilization zebrafish embryos. At 1 day post-injection, xenografts were assessed for tumor size, followed by random allocation into treatment groups with trametinib, luminespib and trametinib + luminespib. Subsequently, xenografts were euthanized and analyzed for apoptosis and proliferation by confocal microscopy. Tumor cells formed compact tumor masses (n = 84) in vivo, with clear Ki67 staining, indicating proliferation. Zebrafish xenografts exhibited sensitivity to trametinib and luminespib, individually or combined, within a two-week period, establishing them as a rapid and complementary tool to existing in vitro and in vivo models for evaluating targeted therapies in LGSOC.

Abstract
OBJECTIVE To investigate the use and outcomes of adjuvant chemotherapy for patients with advanced-stage low-grade serous ovarian carcinoma following primary cytoreductive surgery. METHODS Patients diagnosed between 2010 and 2015 with International Federation of Gynecology and Obstetrics stage II-IV low-grade serous ovarian carcinoma who underwent primary debulking surgery with known residual disease status and had at least 1 month of follow-up were identified in the National Cancer Database. Adjuvant chemotherapy was defined as receipt of chemotherapy within 6 months of surgery. Overall survival was evaluated using the Kaplan-Meier method and compared with the log-rank test. A Cox model was constructed to control for a priori-selected confounders. A systematic review of the literature was also performed. RESULTS In total, 618 patients with stage II-IV low-grade serous ovarian carcinoma who underwent primary cytoreductive surgery were identified; 501 (81.1%) patients received adjuvant chemotherapy, while 117 (18.9%) patients did not. The median follow-up of the present cohort was 47.97 months. There was no difference in overall survival between patients who did and did not receive adjuvant chemotherapy (p=0.78; 4-year overall survival rates were 77.5% and 76.1%, respectively). After controlling for patient age, medical co-morbidities, disease stage, and residual disease status, administration of adjuvant chemotherapy was not associated with better overall survival (HR=0.87, 95% CI 0.55 to 1.38). Based on data from three retrospective studies, omission of adjuvant chemotherapy following cytoreductive surgery was not associated with worse progression-free survival benefit (HR=1.25, 95% CI 0.80 to 1.95) for patients with stage III-V low-grade serous ovarian carcinoma. CONCLUSIONS Adjuvant chemotherapy may not be associated with an overall survival benefit for patients with advanced-stage low-grade serous ovarian carcinoma following primary cytoreductive surgery.

Abstract
Functional properties caused by TP53 mutations are involved in cancer development and progression. Although most of the mutations lose normal p53 functions, some of them, gain-of-function (GOF) mutations, exhibiting novel oncogenic functions. No reports have analyzed the impact of TP53 mutations on the gene expression profile of the p53 signaling pathway across cancer types. This study is a cross-cancer type analysis of the effects of TP53 mutations on gene expression. A hierarchical cluster analysis of the expression profile of the p53 signaling pathway classified 21 cancer types into two clusters (A1 and A2). Changes in the expression of cell cycle-related genes and MKI67 by TP53 mutations were greater in cluster A1 than in cluster A2. There was no distinct difference in the effects between GOF and non-GOF mutations on the gene expression profile of the p53 signaling pathway.

Abstract
OBJECTIVE To investigate the mechanism of alanine aminotransferase 1 (ALT1) in the progression of HCC, the differentially expressed proteins (DEPs) in the ALT1 interaction network were identified by targeted proteomic analysis. METHODS Wound healing and transwell assays were conducted to assess the effect of ALT1 on cellular migration and invasion. Cell Counting Kit-8 (CCK-8), colony formation, and flow cytometry assays were performed to identify alterations in proliferation and apoptosis. After coimmunoprecipitation processing, mass spectrometry with iso-baric tags for relative and absolute quantitation was utilized to explore the protein interactions in ALT1 knockdown HepG2 cells. RESULTS The results showed that ALT1 knockdown inhibits the migration, invasion, proliferation of HepG2 cells, and promotes apoptosis. A total of 116 DEPs were identified and the bioinformatics analysis suggested that the ALT1-interacting proteins were primarily associated with cellular and metabolic processes. Knockdown of ALT1 in HepG2 cells reduced the expression of Ki67 and epithelial cell adhesion molecule (EP-CAM), while the expression of apoptosis-stimulating protein 2 of p53 (ASPP2) was increased significantly. Suppression of the ALT1 and EP-CAM expression contributed to alterations in epithelial-mesenchymal transition (EMT) -associated markers and matrix metalloproteinases (MMPs). Additionally, inhibition of ALT1 and Ki67 also decreased the expression of apoptosis and proliferation factors. Furthermore, inhibition of ALT1 and ASPP2 also changed the expression of P53, which may be the signaling pathway by which ALT regulates these biological behaviors. CONCLUSIONS This study indicated that the ALT1 protein interaction network is associated with the biological behaviors of HepG2 cells via the p53 signaling pathway.

Abstract
Background. GPNMB is a newly discovered tumour-promoting factor that may promote tumour cell progression by activating the PI3K/AKT pathway by EGFR. However, there are insufficient studies about GPNMB in ESCC. This study investigated the relationship between GPNMB and EGFR/PI3K pathway genes in ESCC. Methods. The expression levels of GPNMB, EGFR, p-PI3K, and Ki-67 were examined using immunohistochemistry. Statistical analysis was done by SPSS 22.0 and R. Results. GPNMB mRNA expression is higher in ESCC compared with paracancerous tissues. The expression of EGFR, PIK3CA, PIK3CB, and AKT1 was increased in GPNMB upregulated samples. GPNMB expression was positively correlated with EGFR, p-PI3K, and Ki-67 expression. GPNMB was expressed higher in the AJCC III stage, lymph node metastasis, and moderately poorly differentiated patients. EGFR was higher expressed in patients with vascular invasion; p-PI3K expression in Kazak was higher than that in Han; Ki-67 expression was higher in
. Patients with high expression of GPNMB, p-PI3K, and Ki-67 had worse OS. p-PI3K, Ki-67, nerve invasion, and lymphatic metastasis were independent risk factors, and postoperative adjuvant therapy was a protective factor in ESCC. Conclusion. As a tumour-promoting factor, GPNMB is expected to be a potential target for ESCC.

Abstract
BackgroundAdjuvant chemotherapy has been shown to produce a favorable prognosis for patients with resectable mucosal melanoma (MM), resulting in the need for stratification to optimally select patients to benefit from adjuvant therapy. This study analyzed Ki67 as a potential stratification index for adjuvant chemotherapy in resectable MM.MethodsPatients with resected MM who received subsequent adjuvant therapy in Beijing Cancer Hospital between 2010 and 2018 were retrospectively enrolled and analyzed. Relapse-free survival (RFS) and melanoma-specific survival (MSS) curves were used to perform the survival comparisons across different subgroups.ResultsFrom Jan 2010 to Dec 2018, 1106 MM patients were screened from a database of 4706 patients and 175 of these patients were finally enrolled. A total of 100 patients received temozolomide (TMZ)-based adjuvant chemotherapy and 75 patients received high-dose interferon-α2b (HDI) adjuvant therapy. Compared with HDI, patients who received TMZ-based adjuvant chemotherapy had significantly superior RFS (21.0 vs. 9.6 months, P = 0.002). For patients with low Ki67 expression (<30%), the two regimens showed no significant difference for impact on RFS (33.9 vs. 22.7 months, P = 0.329). However, for patients with high Ki67 expression (≥30%), TMZ-based adjuvant chemotherapy achieved favorable RFS compared with HDI (18.0 vs. 6.7 months, P < 0.001) and tended to improve MSS compared to HDI (41.4 vs. 25.1 months, P = 0.067).ConclusionCompared with HDI, adjuvant chemotherapy may be more relevant for patients with Ki67 ≥ 30%. Ki67 may serve as a potential index to distinguish populations benefiting from adjuvant chemotherapy in resectable MM, and may provide a basis for stratification in the selection of adjuvant regimens.

Low-Grade Serous Carcinoma of the Ovary: The Current Status. Diagnostics (Basel) 2022; 12:diagnostics12020458. [PMID: 35204549 PMCID: PMC8871133 DOI: 10.3390/diagnostics12020458] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Revised: 01/30/2022] [Accepted: 02/04/2022] [Indexed: 11/16/2022] Open
Abstract
Low-grade serous carcinoma (LGSC) of the ovary is a rare histological subtype of epithelial ovarian carcinoma. It has distinct clinical behavior and a specific molecular profile. Compared with high-grade serous carcinoma, this tumor presents at a younger age, has an indolent course, and is associated with prolonged survival. LGSC can arise de novo or originate following a serous borderline tumor (SBT). Pathological differentiation between LGSC and other ovarian carcinoma histological subtypes is fundamental. Several factors might influence the overall outcome, such as the age at diagnosis, current smoking, elevated body mass index, mutational status, hormonal receptors’ expression, and Ki-67 proliferation index. Surgery is the main treatment option in LGSC, and efforts must be maximized to achieve a microscopic residual in metastatic disease. Despite being relatively chemo-resistant, adjuvant platinum-based chemotherapy remains the standard of care in LGSC. Hormonal maintenance therapy after adjuvant chemotherapy results in improved outcomes. Treatment options for disease recurrence include secondary cytoreductive surgery, chemotherapy, hormonal therapy, targeted therapy, and clinical trials. Advancements in genomic studies and targeted therapies are expected to change the treatment landscape in LGSC.

J Obstet Gynaecol Res 2021; 47:3979-3989. [PMID: 34396646 DOI: 10.1111/jog.14981] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 07/14/2021] [Accepted: 07/30/2021] [Indexed: 11/27/2022]
Abstract
AIM The purpose of this study was to investigate whether the Ki67 values were associated with survival for predicting prognosis in patients with advanced ovarian cancer receiving neoadjuvant chemotherapy (NACT). METHODS Among 17 patients treated with NACT, 13 patients were available for tissue samples from matched pre- and post-therapy tissues. Ki67 scores were transformed to a logarithmic scale for the statistical analyses. The optimal cutoff values of the log-phase Ki67 were assessed by receiver operating characteristic (ROC) analysis. Kaplan-Meier analysis, the log-rank test, and Cox regression analysis were carried out to analyze survival. RESULTS The Ki67-decrease and post-NACT Ki67 were the independent factors associated with relapse-free survival (RFS) (p < 0.001 and p = 0.003). No association was observed on overall survival. The optimal cutoff values for the Ki67-decrease and the post-NACT Ki67 were 6.67% and 5.46 based on ROC where the area under ROC curves (AUC) were 1.00 (p < 0.001) with the 100% sensitivity and specificity. The median RFS was 537 days in patients showing Ki67-decrease >6.66% or post-NACT Ki67 level <5.46, while it was 224 days in those with Ki67 decrease ≤6.66% or post-NACT Ki67 level ≥5.46 (p = 0.001). CONCLUSIONS The Ki67-decrease and the lower post-NACT Ki67 are independent factors associated with favorable RFS, indicating that they could be precise biomarker candidates for prognosis in NACT-administered patients with advanced ovarian cancer.

[PMID: 33393626 PMCID: PMC8112845 DOI: 10.1042/bsr20203334] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 11/08/2020] [Accepted: 11/16/2020] [Indexed: 02/07/2023] Open
Abstract
The prognostic value of Ki-67 in nasopharyngeal carcinoma (NPC) was controversial according to previous studies. We aimed to clarify the association between K-67 expression and survival in NPC through meta-analysis. We conducted a meta-analysis to explore the potential prognostic effect of Ki-67 on overall survival (OS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and local recurrence-free survival (LRFS) in NPC. A total of 13 studies comprising 1314 NPC patients were included. High Ki-67 expression was associated with poor OS (hazard ratio [HR]= 2.70, 95% confidence interval [CI]= 1.97-3.71, P<0.001), DFS (HR = 1.93, 95% CI = 1.49-2.50, P<0.001), and LRFS (HR = 1.86, 95% CI = 1.11-3.12, P=0.019). However, there was no significant association between Ki-67 and DMFS (HR = 1.37, 95% CI = 0.78-2.38, P=0.270). Furthermore, the prognostic role of Ki-67 was maintained throughout different sample sizes, analyses of HR, and study designs for OS and DFS in various subgroups. Elevated Ki-67 expression is a reliable prognostic factor for poorer survival outcomes in NPC.

Curcumin Nanoparticle Enhances the Anticancer Effect of Cisplatin by Inhibiting PI3K/AKT and JAK/STAT3 Pathway in Rat Ovarian Carcinoma Induced by DMBA. Front Pharmacol 2021; 11:603235.

Abstract
Cisplatin has been used for decades for the treatment of ovarian cancer. However, despite its potent anticancer effect, cisplatin's efficacy as a single agent was inadequate in patients with advanced stage. Curcumin has been shown to sensitize cisplatin activity in several cancer models. However, the low bioavailability of curcumin has limited its anticancer potential. Hence, nano-formulation of curcumin was developed to increase its therapeutic efficacy in ovarian cancer. The objective of this study was to investigate the mechanism of curcumin nanoparticles given in combination with cisplatin in rat ovarian carcinoma induced by dimethylbenz(a)anthracene (DMBA). The administration of cisplatin and nanocurcumin resulted in a significant reduction in ovarian tumor volume and weight. Furthermore, there were reduction in expressions of Ki67, TGF-β, PI3K, and Akt phosphorylation. Co-treatment of cisplatin and nanocurcumin also reduced JAK expression, STAT3 phosphorylation, and reduced IL-6 concentrations. Altogether, nanocurcumin, given as a co-treatment with cisplatin has therapeutic potential in ovarian cancer models by inhibiting proliferation through downregulation of PI3K/Akt and JAK/STAT3 signaling pathways.

Lymphovascular space invasion and Ki67 as predictors of lymph node metastasis in primary low grade serous ovarian cancer. Int J Gynecol Cancer 2020; 31:98-103. [PMID: 33127866 DOI: 10.1136/ijgc-2020-001950] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 10/12/2020] [Accepted: 10/15/2020] [Indexed: 12/24/2022] Open
Abstract
OBJECTIVE Low grade serous ovarian cancers characterize a unique clinical pattern and likely less frequent incidence of lymphatic metastasis. The expression level of Ki67 is associated with differences in prognosis and therapy outcome. However, its expression in combination with lymphovascular space invasion has not been evaluated in the prediction of lymphatic metastasis. METHODS Patients with low grade serous ovarian cancer were identified in an institutional database. Patients with primary low grade serous ovarian cancer diagnosed and/or treated at our center between September 2000 and December 2018 were identified. Receiver operator characteristics curve analysis was performed to find the cut-off values of per cent Ki67 to discriminate patients with lymph node metastasis. The association between the presence of lymphovascular space invasion and lymph node involvement was analyzed. RESULTS A total of 109 patients with primary low grade serous ovarian cancer were identified in our institution's database. Of these, 72 (66.1%) patients underwent primary surgery with pelvic and para-aortic lymph node dissection. Complete data for Ki67 expression and lymphovascular space invasion were obtained for 61 (84.7%) of these patients. Among them, 37 (60.7%) patients had lymph node metastasis. The presence of lymphovascular space invasion was associated with an increased risk of lymph node metastases (odds ratio (OR)=12.78, 95% confidence interval (CI) 3.15 to 51.81; p<0.001). In multivariate analysis including age >65 years, peritoneal carcinomatosis, and ascites>500 mL, lymphovascular space invasion remained a significant risk factor for lymphatic metastases (OR=35.11, 95% CI 2.38 to 517.69; p=0.010). Ki67 ≥6% was associated with a higher risk of lymphovascular space invasion (OR=3.67, 95% CI 1.26 to 10.64; p=0.017). No significant correlation between Ki67 expression level and nodal metastases was found (OR=2.19, 95% CI 0.76 to 6.26; p=0.14). Neither presence of lymphovascular space invasion or nodal metastases was associated with a statistically poorer prognosis. CONCLUSIONS We showed an association between lymphovascular space invasion, Ki67 expression, and risk of lymph node metastasis in primary low grade ovarian cancer. Further prospective trials evaluating lymphovascular space invasion and Ki-67 as predictors of lymph node metastasis are needed.

Role of delayed interval debulking for persistent residual disease after more than 5 cycles of chemotherapy for primary advanced ovarian cancer. An international multicenter study. Gynecol Oncol 2020; 159:434-441. [PMID: 32919778 DOI: 10.1016/j.ygyno.2020.08.028] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Accepted: 08/23/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Standard of care in patients with advanced ovarian cancer (AOC) is upfront surgery followed by chemotherapy. Neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS) is an alternative in selected patients. Most data exist with IDS following 3-4 cycles chemotherapy, however, some patients experience a delay of IDS. So far, the impact of a "delayed" interval debulking surgery (DID) is poorly defined. METHODS We analyzed data from eight international gynecology-oncology referral centers. Patients were included if they had newly diagnosed AOC and were prone to DID (minimum 5 cycles of NACT) between 2011 and 2017. RESULTS 308 patients underwent DID. 89.6% had a high-grade serous ovarian cancer. The median number of pre-op NACT was 6 cycles (range 5-9) and 6.1% of patients received additionally bevacizumab. The majority of patients had stage-IV disease (51.3%). Median duration of surgery was 210 min (range 34-561), the median surgical complexity score was 4 (range 1-16). Complete resection was achieved in 60.1%. The median number of post-op chemotherapy cycles was 2 (range 0-5). The rate of severe complications (Clavien-Dindo£3°) was 9.7% and 30 days post-op mortality was 0.3%. The median PFS and OS in patients with complete resection was 19.5 and 49.2 months compared to 14.8 and 33.0 months in patients with incomplete resection (p = 0.001), respectively. We did not observe any survival benefit for patients with cytoreduction to small residuals (1-10 mm) compared to residual disease >1 cm. CONCLUSION Our data may suggest that offering surgery to patients with persistent disease after 5+ cycles could be associated with favorable outcome if a complete resection is achieved. Patients who had residual disease postoperatively may experience rather peri-operative treatment burden than any benefit from DID.
