OBJECTIVES:
To evaluate the performance of a multi-constraint representation learning classification model for identifying ovarian cancer with missing laboratory indicators.
METHODS:
Tabular data with missing laboratory indicators were collected from 393 patients with ovarian cancer and 1951 control patients. The missing ovarian cancer laboratory indicator features were projected to the latent space to obtain a classification model using the representational learning classification model based on discriminative learning and mutual information coupled with feature projection significance score consistency and missing location estimation. The proposed constraint term was ablated experimentally to assess the feasibility and validity of the constraint term by accuracy, area under the ROC curve (AUC), sensitivity, and specificity. Cross-validation methods and accuracy, AUC, sensitivity and specificity were also used to evaluate the discriminative performance of this classification model in comparison with other interpolation methods for processing of the missing data.
RESULTS:
The results of the ablation experiments showed good compatibility among the constraints, and each constraint had good robustness. The cross-validation experiment showed that for identification of ovarian cancer with missing laboratory indicators, the AUC, accuracy, sensitivity and specificity of the proposed multi-constraints representation-based learning classification model was 0.915, 0.888, 0.774, and 0.910, respectively, and its AUC and sensitivity were superior to those of other interpolation methods.
CONCLUSIONS
The proposed model has excellent discriminatory ability with better performance than other missing data interpolation methods for identification of ovarian cancer with missing laboratory indicators.

Primary female genital system lymphoma(PFGSL)is a rare subtype of extranodal lymphoma and patients commonly present in the department of gynecology.At present,there is a lack of uniform standards for the treatment of PFGSL.Although the classification of lymphoid neoplasmas was updated by the World Health Organization classification of haematolymphoid tumors in 2016,PFGSL was still not elaborated in sufficient detail.Most cases of PFGSL are non-Hodgkin lymphoma,involving the ovary and cervix.In some cases,involvement of uterine corpus,vagina,and vulva is reported.In this article,we report two cases of non-Hodgkin lymphoma in the female genital system,one from the uterus and the other from the ovary.By presenting the diagnosis and treatment of the two cases and reviewing the literature,we aim to provide a reference for clinicians in recognizing and treating rare cases.

Objective To assess the value of the MRI-based ovarian-adnexal reporting and data system (O-RADS MRI) for the diagnosis of adnexal masses. Methods A total of 407 patients who underwent dynamic contrast enhancement (DCE)-MRI and pathological examination (gold standard) at the Department of Radiology,Central Hospital of Wuhan between May 2017 and December 2022 were enrolled in this study.Two radiologists performed the O-RADS MRI scoring of adnexal masses according to MRI features and calculated the malignancy rate of adnexal masses by O-RADS MRI score,enhancement type,and mass type.Moreover,receiver operating characteristic curves were established to further evaluate the diagnostic values of O-RADS MRI score,enhancement type,and mass type for adnexal masses. Results A total of 502 adnexal masses were identified in the 407 patients enrolled in this study,including 364 benign masses and 138 malignant masses (including junctional masses).Radiologist 1 reported the malignancy rates of 0,0,5.4%,80.0%,and 89.7% and radiologist 2 reported the malignancy rates of 0,0,5.8%,86.2%,and 83.0% for the adnexal masses with the O-RADS MRI scores of 1-5,respectively.With O-RADS MRI ≥4 indicating malignant masses,the sensitivity,specificity,accuracy,positive predictive value,negative predictive value,false negative rate,and false positive rate were 94.2%,93.6%,93.8%,84.9%,97.7%,2.3%,and 15.1% for radiologist 1 and 93.4%,93.6%,93.6%,85.4%,97.4%,3.6%,and 14.6% for radiologist 2,respectively.The malignancy rates of the adnexal masses presenting no enhancement,cystic wall enhancement,type Ⅰ curve,type Ⅱ curve,and type Ⅲ curve were 0,1.3%,5.7%,81.2%,and 89.0% as reported by radiologist 1 and 0,1.2%,11.3%,87.6%,and 80.0% as reported by radiologist 2,respectively.The malignancy rates of the adnexal masses that were cystic lesions,cystic segregated lesions,solid lesions,cystic solid lesions,and cystic solid segregated lesions were 0,7.1%,38.7%,79.1%,and 89.8% as reported by radiologist 1 and 0,8.1%,37.8%,72.4%,and 89.6% as reported by radiologist 2,respectively.With type Ⅱ and type Ⅲ curves as the criteria for malignancy,the sensitivity of radiologists 1 and 2 was lower for cystic segregated lesions,both at 50.0%.For the masses containing solid components,radiologists 1 and 2 demonstrated low specificity,which was 57.7% and 56.5%,respectively.False-positive masses contained solid components and were mostly fibroadenomas or adnexal leiomyomas,while false-negative masses were mostly junctional cystadenomas with no or few solid components. Conclusions The O-RADS MRI risk stratification has a high diagnostic value for adnexal masses.Further evaluation and refinement are needed to reduce the false-positive rate.

Objective: To investigate the cytomorphological and immunocytochemical features of tumor cells in the ascites of ovarian plasmacytoma (SOC). Methods: Specimens of serous cavity effusions were collected from 61 tumor patients admitted to the Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2015 to July 2021, including ascites from 32 SOC, 10 gastrointestinal adenocarcinomas, 5 pancreatic ductal adenocarcinomas, 6 lung adenocarcinomas, 4 benign mesothelial hyperplasia and 1 malignant mesothelioma patients, pleural effusions from 2 malignant mesothelioma patients and pericardial effusion from 1 malignant mesothelioma. Serous cavity effusion samples of all patients were collected, conventional smears were made through centrifugation, and cell paraffin blocks were made through centrifugation of remaining effusion samples. Conventional HE staining and immunocytochemical staining were applied to observe and summarize cytomorphological characteristics and immunocytochemical characteristics. The levels of serum tumor markers carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) were detected. Results: Of the 32 SOC patients, 5 had low-grade serous ovarian carcinoma (LGSOC) and 27 had high-grade serous ovarian carcinoma (HGSOC). 29 (90.6%) SOC patients had elevated serum CA125, but the difference was not statistically significant between them and patients with non-ovarian primary lesions included in the study (P>0.05); The serum CEA was positive in 9 patients with gastrointestinal adenocarcinoma and 5 patients with lung adenocarcinoma, and the positive rate was higher than that in SOC patients (P<0.001); The serum CA19-9 was positive in 5 patients with gastrointestinal adenocarcinoma and 5 patients with pancreatic ductal adenocarcinoma, and the positive rate was higher than that in SOC patients (P<0.05). The serum CA125, CEA and CA19-9 were within the normal range in 4 patients with benign mesothelial hyperplasia. LGSOC tumor cells were less heterogeneous and aggregated into small clusters or papillary pattern, and psammoma bodies could be observed in some LGSOC cases. The background cells were fewer and lymphocytes were predominant; the papillary structure was more obvious after making cell wax blocks. HGSOC tumor cells were highly heterogeneous, with significantly enlarged nuclei and varying sizes, which could be more than 3-fold different, and nucleoli and nuclear schizophrenia could be observed in some cases; tumor cells were mostly clustered into nested clusters, papillae and prune shapes; there were more background cells, mainly histiocytes. Immunocytochemical staining showed that AE1/AE3, CK7, PAX-8, CA125, and WT1 were diffusely positively expressed in 32 SOC cases. P53 was focally positive in all 5 LGSOCs, diffusely positive in 23 HGSOCs, and negative in the other 4 HGSOCs. Most of adenocarcinomas of the gastrointestinal tract and lung had a history of surgery, and tumor cells of pancreatic ductal adenocarcinoma tend to form small cell nests. Immunocytochemistry can assist in the differential diagnosis of mesothelial-derived lesions with characteristic "open window" phenomenon. Conclusion: Combining the clinical manifestations of the patient, the morphological characteristics of the cells in the smear and cell block of the ascites can provide important clues for the diagnosis of SOC, and the immunocytochemical tests can further improve the accuracy of the diagnosis.

OBJECTIVES:
International Ovarian Tumor Analysis (IOTA) working group proposed a logistic regression (IOTA LR2) model. It is served as a risk prediction model for benign and malignant adnexal tumors. This study aims to compare the diagnostic efficiency between the IOTA LR2 model and doctors' subjective assessment on diagnosing benign and malignant adnexal mass.
METHODS:
The ultrasonographic images of 616 adnexal masses were retrospectively analyzed by the senior doctors' group and the junior doctors' group using the IOTA LR2 model and subjective assessment. The postoperative pathological diagnosis was used as the gold standard to compare the diagnostic efficiency of the 2 methods.
RESULTS:
The area under the curves of subjective assessment and IOTA LR2 model for diagnosing malignant adnexal masses were 0.86 and 0.90 for the senior doctors' group and 0.79 and 0.88 for the junior doctors' group, respectively. The sensitivity and specificity of subjective assessment for diagnosing the malignant adnexal masses were 81.0% and 91.3% for the senior doctors' group and 70.1% and 88.7% for the junior doctors' group, respectively. The sensitivity and specificity of the IOTA LR2 model for diagnosing the malignant adnexal masses were 79.6% and 88.1% for the senior doctors' group, and 79.6% and 81.7% for the junior doctors' group, respectively.There were no significant difference in the sensitivities between the senior doctors' group and junior doctors' group using the IOTA LR2 model and the senior doctors' group using subjective assessment (both P>0.05).
CONCLUSIONS
The diagnostic efficiency of the IOTA LR2 model is equal to the senior doctors' experiences. This model can help junior doctors to reduce the missed diagnosis of malignant adnexal masses.

Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than in the ovarian thecoma-fibroma (OTF) and healthy control groups (all P < 0.05). However, the serum HE4 levels were lower in the MS group than in the OC group (P < 0.001). A routine blood test showed that the absolute counts and percentages of lymphocytes were significantly lower in the MS group than in the OTF and control groups (all P < 0.05). However, these variables were higher in the MS group than in the OC group (both P < 0.05). The neutrophil-to-lymphocyte ratio (NLR) was also significantly lower, whereas the lymphocyte-to-monocyte ratio was higher in the MS group than in the OC group (both P < 0.05). The NLR, platelet-to-lymphocyte ratio, and systemic immune index were significantly higher in the MS group than in the OTF and control groups (all P < 0.05). The hypoxia-inducible factor-1 mRNA levels were also significantly higher, whereas the glucose transporter 1, lactate dehydrogenase, and enolase 1 mRNA levels were lower in peripheral CD4

ovarian cancer treated with NACT from 7/1/15–12/1/17. Fisher exact and Wilcoxon rank-sum tests were used to compare clinical characteristics by surgical status. The Kaplan-Meier method was used to estimate survival outcomes. Log-rank test and Cox proportional hazards model were applied to assess the relationship of covariates to outcome, and time-dependent covariates were applied to variables collected after diagnosis.RESULTS: Of 224 women who received NACT, 162 (72%) underwent IDS and 62 (28%) did not undergo surgery. The non-surgical group was older (p<0.001), had higher Charlson comorbidity index (CCI; p<0.001), lower albumin levels (p=0.007), lower Karnofsky performance scores (p<0.001), and were more likely to have dose reductions in NACT (p<0.001). Reasons for no surgery included poor response to NACT (39%), death (15%), comorbidities (24%), patient preference (16%), and loss to follow-up (6%). The no surgery group had significantly worse overall survival (OS) than the surgery group (hazard ratio=3.34; 95% confidence interval=1.66–6.72; p<0.001), after adjustment for age, CCI, and dose reductions.CONCLUSIONS: A significant proportion of women treated with NACT do not undergo IDS, and these women are older, frailer, and have worse OS. More studies are needed to find optimal therapies to maximize outcomes in this high-risk, elderly population.]]>

ovarian cancer (EOC), both in primary and recurrent disease. Our aim was to identify criteria to select elderly patients who can safely benefit from bevacizumab addition.METHODS: This is a case-control study on patients with primary or recurrent EOC who received platinum-based chemotherapy plus bevacizumab, between January 2015 and December 2016. Patient characteristics, treatment details and adverse events were reviewed and analyzed in 2 settings: younger (<65 years, group 1) and elderly (≥65 years, group 2). A binary logistic model was applied to correlate clinical variables and severe (grade ≥3) toxicity risk.RESULTS: Overall, 283 patients with EOC were included, with 72 (25.4%) older patients compared with 211 (74.6%) younger women. Bevacizumab had been administered to 234 patients (82.7%) as first-line treatment and in 49 (17.3%) with recurrent disease. At diagnosis, elderly patients presented with at least one comorbidity and were taking at least 1 medication in 84.7% and 80.6% of the cases respectively, compared with correspondingly 47.4% and 37.4% in group 1 (p<0.001). Nonetheless, the occurrence of serious (grade ≥3) adverse events did not increase among the older group. Creatinine serum levels >1.1 g/dL, estimated glomerular filtration rate (eGFR) ≤60 mL/min, ≥3 comorbidities were independently associated with a higher severe toxicity.CONCLUSIONS: Elderly patients with EOC can safely be treated with bevacizumab; factors other than age, as higher creatinine serum levels, eGFR and number of comorbidities should be considered to better estimate bevacizumab-related toxicity risk.]]>

OBJECTIVE: Patients with endometriosis are at increased risk of ovarian cancer. It has been suggested that atypical endometriosis is a precursor lesion of endometriosis-associated ovarian cancer (EAOC). The aim of this study is to evaluate if cytologic (cellular) atypia and architectural atypia (hyperplasia), histologic findings described as atypical endometriosis, play a different role in patients with EAOC. METHODS: A prospective study was conducted between January 2014 and April 2017 at our institution with patients undergoing surgery with a histologic diagnosis of endometriosis, ovarian cancer, or EAOC. The prevalence and immunohistologic study (Ki-67, BAF250a, COX-2) of cases of cellular and architectural atypia in endometriosis were analyzed. RESULTS: Two hundred and sixty-six patients were included: the diagnosis was endometriosis alone in 159 cases, ovarian cancer in 81, and EAOC in 26. Atypical endometriosis was reported in 23 cases (12.43%), 39.13% of them found in patients with EAOC. Endometriosis with cellular atypia was found mainly in patients without neoplasm (71.4%), and endometriosis with architectural atypia was seen in patients with ovarian cancer (88.9%) (p=0.009). Ki-67 was significantly higher in endometriosis patients with architectural atypia than those with cellular atypia. CONCLUSION: The diagnosis of endometriosis with architectural atypia is important because it may be a precursor lesion of ovarian cancer; therefore, pathologists finding endometriosis should carefully examine the surgical specimen to identify any patients with hyperplasia-type endometriosis, as they may be at higher risk of developing EAOC.
