Mounting studies have shown that the oncoproteins E6 and E7 encoded by the human papillomavirus (HPV) genome are essential in HPV-induced cervical cancer (CC). Ca 2+ binding protein 1 (CABP1), a downstream target of HPV18-positive HeLa cells that interferes with E6/E7 expression, was identified through screening the GEO Database (GSE6926). It was confirmed to be down-regulated in CC through TCGA prediction and in vitro detection. Subsequent in vitro experiments revealed that knocking down E6/E7 inhibited cell proliferation, migration, and invasion, whereas knocking down CABP1 promoted these processes. Simultaneously knocking down CABP1 reversed these effects. Additionally, the results were validated in vivo. Previous studies have indicated that CABP1 can regulate Ca 2+ channels, influencing Ca 2+ influx and tumor progression. In this study, it was observed that knocking down CABP1 enhanced Ca 2+ inflow, as demonstrated by flow cytometry and confocal microscopy. Knocking down E6/E7 inhibited these processes, whereas simultaneously knocking down E6/E7 and CABP1 restored the inhibitory effect of knocking down E6/E7 on Ca 2+ inflow. To further elucidate that E6/E7 promotes CC progression by inhibiting CABP1 expression and activating Ca 2+ influx, BAPTA/AM treatment was administered during CABP1 knockdown. It was discovered that Ca 2+ chelation could reverse the effect of CABP1 knockdown on CC cells. In conclusion, our results offer a novel target for the diagnosis and treatment of HPV-induced CC., (© 2024 International Union of Biochemistry and Molecular Biology, Inc.)

Plain language summary: Biomarkers may offer unforeseen insights into clinical diagnosis, as well as the likely course and outcome of a condition. In this paper, the focus is on the use of biological molecules found in body fluids or tissues for diagnosis and prediction of outcome in ovarian cancer patients. In cancer care, biomarkers are being used to develop personalised treatment plans for patients based on the unique characteristics of their tumour. This tailoring of care can be used to pursue specific targets identified by biomarkers, or treat the patient according to specific tumour characteristics. Surgery is one of the core treatments for ovarian cancer, whether it is offered in primary surgery or following chemotherapy in delayed surgery. Biomarkers already exist to guide the treatment of tumours with chemotherapy, but very little research has determined the value of biomarkers in tailoring surgical care for ovarian cancer. Such research is required to identify new biomarkers and assess their effectiveness in a clinical setting as well as to help identify specific tumour types to guide surgery. Biomarkers could help to determine the success of removing the disease surgically, or help to identify tumour deposits that persist after chemotherapy. All of these aspects would improve current practice. This Scientific Impact Paper highlights research that may pave the way towards bespoke surgery according to the biological characteristics of a tumour and aid gynaecological oncologists to provide surgical treatment according to individual need, rather than a blanket approach for all.

Aim: Antenatal suspicion of placenta accreta spectrum (PAS) currently relies on ultrasonographic findings, color doppler, and MRI, which have rendered it operator and expertise‐dependent. No serum markers for PAS have been integrated into clinical practice yet. The aim of this meta‐analysis was to identify potential serum markers for PAS by investigating third‐trimester serum levels of vascular endothelial growth factor (VEFG), placental growth factor (PIGF), and soluble Fms‐like tyrosine kinase‐1 (sFlt‐1) among PAS‐cases and controls. Methods: PubMed, Scopus, EBSCO, Web of Science, and CNKI databases were systematically searched for relevant articles. Random‐effects model was applied to calculate the overall standardized mean difference (SMD) for each marker. Subgroup analysis and meta‐regression were performed to assess for potential covariates. Results: Eight studies involving 366 PAS‐cases and 518 controls were included. Third trimester sFlt‐1 levels were significantly lower in PAS‐cases when compared to controls (SMD = −7.76, 95%CI = −10.42 to −5.10). This was, to a certain extent, consistent among studies though they differed in their extent of significance. Levels of VEGF (SMD = 1.59, 95%CI = −0.07 to 3.25) and PlGF (SMD = −0.49, 95%CI = −1.66 to 0.67) were not significantly different between PAS cases and controls, in which studies demonstrated conflicting results. Conclusions: Third trimester sFlt‐1 levels may be useful to predict PAS. Nonetheless, further studies are recommended to better understand conflicting results before adopting either VEGF or PlGF.

Aim: We devised a simplified nerve‐sparing radical hysterectomy that is simpler than commonly used procedures. Methods: We retrospectively examined 16 cases of classical non‐nerve‐sparing radical hysterectomy (non‐nerve‐sparing group) and 16 cases of simplified nerve‐sparing radical hysterectomy (nerve‐sparing group) performed between 2019 and 2020. We examined and compared the duration of surgery, blood loss, perioperative complications, postoperative urinary function (presence or absence of urinary sensation, number of days with residual urine measurement, and frequency and duration of oral sustained release urapidil capsules and self‐catheterization), and short‐term prognosis between the two groups. Results: Compared to conventional non‐nerve‐sparing radical hysterectomy, the duration of surgery for nerve‐sparing radical hysterectomy was significantly shorter (407 [339–555] min vs. 212 [180–356] min; p < 0.001), and blood loss was significantly less. Compared to the nerve‐sparing group, the non‐nerve‐sparing group had more cases of oral urapidil use and a higher frequency of clean intermittent catheterization. Clean intermittent catheterization was required in two cases in the nerve‐sparing group; however, it was withdrawn at 180 and 240 days. Conversely, clean intermittent catheterization was still required in three cases in the non‐nerve‐sparing group. There were no statistically significant differences in progression‐free survival and overall survival between the two groups. Conclusion: The simple nerve‐sparing radical hysterectomy resulted in shorter duration of surgery and less blood loss as well as in a clear improvement in the postoperative urinary status and short‐term prognosis. This technique simplifies nerve‐sparing radical hysterectomy, which is commonly thought to be complicated, making it easier to understand. [ABSTRACT FROM AUTHOR]

Aim: Gynecological sarcomas (GS) are rare malignant tumors arising in the female genital organs. Due to the low incidence and diverse histology, information on the epidemiology of these tumors is sparse. We aimed to investigate the incidence rates of GS in Iran that in our knowledge is the first report from Eastern Mediterranean Region. Methods: In this retrospective study, all malignant tumors with a sarcoma morphology arising in the female genital organs diagnosed between 2009 and 2014 were extracted from the Iran National Cancer Registry dataset. All the cancer cases were categorized according to ICD‐O‐3 morphologic and topographic codes. Age‐standardized incidence rates, age‐specific incidence rates, morphologic and geographic distribution of all cases were analyzed and compared with other parts of the world. Results: A total of 1174 cases were diagnosed over the period 2009–2014. The overall age‐standardized incidence rate for all sites combined was 6.13 per million females. Analysis of trends in incidence did not show a significant change over time according to annual average percent change analysis (P‐value = 0.300). The most common anatomical site was the uterus, accounting for 77% of all cases. The mean (±SD) age at diagnosis, irrespective of tumor site, was 52.3 (±15) years. In terms of morphology, leiomyosarcoma was the most frequently observed subtype, constituting 34% of all GS. Also, the highest ASIR was observed in women aged 60–64 years. Conclusion: Based on the findings, GS are relatively rare tumors that occur more in old women. The results of this study provide a comprehensive picture of GS incidence patterns in Iran for more investigation. [ABSTRACT FROM AUTHOR]

Ovarian cancer is one of the most challenging diseases in gynecologic oncology. The presentation of frequent recurrences requires the establishment and further development of therapy standards for this patient group. Surgery is crucial in the therapy of patients with primary ovarian cancer, and the postoperative residual tumor mass is the most relevant clinical prognostic factor. The surgical management of recurrent disease is still subject to an emotional international discussion. Only a few prospective clinical trials focused on the effects of surgery in relapsed ovarian cancer have been published. The available data show improvements in the prognosis due to complete cytoreduction in the setting of recurrence. However, the selection of eligible patients is the essential issue. Therefore, the establishment of reliable predictive factors for complete tumor resection as well as a definition of the group of patients who might profit from this approach remains a field for research. Further randomized trials designed to develop and incorporate operative standards for recurrent ovarian cancer should follow. [ABSTRACT FROM AUTHOR]

Of all the gynecologic tumors, ovarian cancer (OC) is known to be the deadliest. Advanced‐stages of OC are linked with high morbidity and low survival rates despite the immense amount of research in the field. Shortage of promising screening tools for early‐stage detection is one of the major challenges linked with the poor survival rate for patients with OC. In OC, therapeutic management is used with multidisciplinary approaches that includes debulking surgery, chemotherapy, and (rarely) radiotherapy. Recently, there is an increasing interest in using immunomodulation for treating OC. Relapse rates are high in this malignancy and averages around every 2‐years. Further treatments after the relapse are more intense, increasing the toxicity, resistance to chemotherapy drugs, and financial burden to patients with poor quality‐of‐life. A procedure that has been studied to help reduce the morbidity rate involves pre‐sensitizing cancer cells with standard therapy in order to produce optimal results with minimum dosage. Utilizing such an approach, platinum‐based agents are effective due to their increased response to platinum‐based chemotherapy in relapsed cases. These chemo‐drugs also help address the issue of drug resistance. After conducting an extensive search with available literature and the resources for clinical trials, information is precisely documented on current research, biomarkers, options for treatment and clinical trials. Several schemes for enhancing the therapeutic responses for OC are discussed systematically in this review with an attempt in summarizing the recent developments in this exciting field of translational/clinical research.

Introduction: The aim was to evaluate surgical treatment of newly diagnosed uterine cancer in a Swedish population.Material and Methods: Data in the GynOp registry from 2008 to 2014 were analyzed.Results: In total, 3443 cases were included: 430 (12%) were robotic-assisted laparoscopic, 272 (8%) laparoscopic, and 2741 (80%) abdominal operations. There was an increasing trend in minimally invasive surgery from 2008 to 2014 (41%). Women with lymph nodes removed in the robotic-assisted laparoscopic group experienced less blood loss (mean 105 vs. 377 mL), shorter length of hospital stay (2.4 vs. 4.1 days), and fewer days to normal activities of daily living (6.5 vs. 12.7 days) (all p < 0.001) compared with the abdominal group, but operating time did not differ. Similar results were found in women with no lymph node removal and in women with body mass index ≥35. Major complications during hospital stay, reoperations, and time to work were less in both minimally invasive groups. More lymph nodes were retrieved in the abdominal (mean 34.4) than in the robotic-assisted laparoscopic (mean 26.0) group, but the number of women with lymph node metastases did not differ, totaling 211/960 (21.9%; 95% CI 19.4-24.7%). Isolated para-aortic lymph node metastases were found in 3.9% (95% CI 2.4-5.6%) of women.Conclusions: Minimally invasive surgery in uterine cancer patients reduces days to normal activities of daily living, number of days to return to work, length of hospital stay, and blood loss in patients without and with lymph node dissection and in obese patients.
