Objective To understand the latest research developments of the formation mechanism of psammoma body in human tumors and related issues. Methods Related domestic and foreign literatures were widely referred, analyzed, and reviewed. Results Psammoma body is unique pathological calcification in some tumors, which is arranged in concentric, laminar circles microscopically. Psammoma body is commonly seen in thyroid papillary carcinoma, meningiomas, ovarian serous papillary carcinoma, and so on. Conclusions Although arranged in concentric, laminar circles microscopically in tumor, the formation process of psammoma body is not entirely the same in different tumors. A comprehensive and objective understanding of psammoma body would be useful in cancer diagnosis and treatment.

The mortality rate of ovarian cancer is the highest among female reproductive tract malignancies. Although most patients have undergone recurrent treatments such as surgery, chemotherapy, and targeted therapy, the recurrence rate is still high. The exploration of scholars in this field has never stopped. In recent years, remarkable achievements have been made in the medical treatment of ovarian cancer. The research of poly adenosinediphosphate-ribose polymerase, immunotherapy (immunocheckpoint inhibitor monotherapy, immune checkpoint inhibitor combined with other drugs) and anti-angiogenic drugs have provided new methods for the treatment of this disease, and throughout the whole process of ovarian cancer treatment. This paper summarizes this, and aims to provide a reference for the clinical treatment of ovarian cancer.
Objective To estimate the diagnostic value of mesothelin in ovarian cancer. Methods PubMed, The Cochrane Library, CBM, CNKI and WanFang Data databases were searched from inception to October 2016 to collect relevant diagnostic accuracy studies of mesothelin in ovarian cancer. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Statistical analysis was performed using Meta-Disc 1.4, Stata 12.0 and RevMan 5.2 softwares. The pooled sensitivity, specificity and diagnostic odds ratio were calculated, the summary receiver operating characteristic curve (SROC) was drawn and the area under the curve (AUC) was calculated. Results Seventeen studies involving 2 052 patients were included. The pooled sensitivity, specificity, DOR were 0.63 (95%CI 0.60 to 0.67), 0.92 (95%CI 0.90 to 0.93) and 26.62 (95%CI 14.96 to 47.38), respectively. The AUC and Q index were 0.915 1 and 0.847 8, respectively. Conclusion The current evidence indicates that mesothelin has high specificity and low sensitivity, which can’t be used alone as a biomarker for the detection of ovarian cancer, but should be combined with other biomarkers.
Objective To analyze the reason of tumor treatment-related premature ovarian failure, and to review the progress of ovarian functional reconstruction. Methods The l iterature about the effects of radiotherapy and chemotherapy on ovarian function and reconstruct ovarian function was reviewed, analysed and summarized. Results Radiotherapy and chemotherapy can both affect ovarian function. The ovarian function reconstruction included fresh ovarian transplantation and ovarian cryopreservation and transplantation. Frequent ovarian cryopreservation was procedure slow-freezing protocols and vitrification protocols. Some laboratory and animal models of ovarian function reconstruction have come to gratifying results. Conclusion Ovarian function reconstruction has a potential cl inical value and provides a promising future.
ObjectiveTo systematically review the effect of laparoscopy versus laparotomy for borderline ovarian tumors (BOTs) on postoperative recurrence. MethodsWe searched PubMed, The Cochrane Library (Issue 11, 2015), EMbase, Web of Science, CNKI, WanFang Data and CBM databases from inception to Nov. 2015, to collect relevant clinical studies comparing laparoscopy and laparotomy for BOTs. Two reviewer independently screened literature, extracted data and assessed the risk of bias of include studies by using NOS scale. Then, meta-analysis was performed by using RevMan 5.3 software. ResultsNineteen cohort studies were included. The scores of NOS scale showed that 10 studies were < 7 points, while the other 9 studies were≥7 points. The results of meta-analysis showed that: the recurrence rate of tumor (OR=1.75, 95%CI 1.05 to 2.91, P=0.03) in the laparoscopy group was higher than that in the laparotomy group, but no significant differences were found in further subgroup analysis according to type of operations (conservative surgery: OR=1.22, 95%CI 0.71 to 2.08, P=0.47; non-conservative surgery: OR=4.38, 95% CI 0.85 to 22.68, P=0.08). The diameter of tumor in the laparoscopy group was significant smaller than that in the laparotomy group (MD=-6.88, 95% CI-8.15 to-5.61, P < 0.000 01), and the rate of rupture of tumor in the laparoscopy group was significant higher than that in the laparotomy group (OR=3.99, 95% CI 2.54 to 6.26, P < 0.000 01). ConclusionCurrent evidence shows, compared with laparotomy, laparoscopy has similar effect on postoperative recurrence and smaller diameter of tumor, but laparoscopy could increase the rate of rupture of tumor. Due to the limited quality and sample size of included studies, more high quality and large sample size studies are need to prove the above conclusion.
Objective To explore the status of women’s quality of life and analyze risk factors related diminished ovarian reserve (DOR). Methods We applied the method of convenient sampling to investigate 61 patients with DOR (DOR group) and 60 women with normal ovarian reserve function (control group) who visited a reproductive centre of a Triple-A hospital from February to May 2013, using a questionnaire which included basic information table, Menopausal Quality of Life Scale (MENQOL) and SF-36 Health Survey for quality of life, and Kupperman Index Scale (KI) for the degree of clinical symptoms. Then, statistical analysis was performed using SPSS 17.0 software. Results Compared with the control group (43.60±16.82), the level of women’s quality of life in the DOR group (73.42±24.15) was significantly lower (Plt;0.01), while the degree of clinical symptoms was significantly higher (Plt;0.01). There were positive associations between quality of life and degree of clinical symptoms. The risk factors related to DOR were various such as age, weight, quality of sleep, menstrual disorders, number of abortion, age of the first pregnancy, gynecologic surgery, economic income, education, family relationship, unsatisfactory sexual life, and psychological factors. Conclusion In order to improve women’s quality of life, effective treatment should be conducted to relieve clinical symptoms of women with DOR. Good life style, harmonious family relationship, healthy mind and avoiding the risk factors, which could effectively help the prevention and treatment of the disease.

Objective To systematically review the diagnostic value of 18F-FDG PET/CT in recurrent epithelial ovarian cancer after treatment. Methods The PubMed, EMbase, Cochrane Library, Web of Science, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to collect diagnostic tests of 18F-FDG PET/CT for epithelial ovarian cancer from inception to February 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Meta-Disc 1.4 and Stata 15.0 software. Results A total of 15 studies involving 792 patients were included in this study. The results of meta-analysis showed that the sensitivity, specificity, and area under the curve of 18F-FDG PET/CT in the diagnosis of recurrent epithelial ovarian cancer were 0.88 (95%CI 0.85 to 0.90), 0.80 (95%CI 0.75 to 0.85) and 0.91, respectively. The results of the subgroup analysis showed that the sensitivity of the prospective studies was the same as that of the retrospective studies, but the specificity of the prospective studies was higher than that of the retrospective studies. The diagnostic sensitivity and specificity of 18F-FDG PET/CT in recurrent epithelial ovarian cancer were higher in Asian studies than in European/North American studies. Conclusion 18F-FDG PET/CT has high diagnostic value in recurrent epithelial ovarian cancer. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
