The prognostic impact of preoperative CA19-9 on resectable cholangiocarcinoma: a comprehensive systematic review and meta-analysis

BackgroundThis study aimed to determine the prognostic survival impact of preoperative carbohydrate CA19-9 levels in resectable cholangiocarcinoma.MethodsPubMed, Web of Science, Cochrane, and Embase databases were searched for articles published through April 28, 2023. The relationship between preoperative serum carbohydrate antigen 19-9 and the prognosis of patients with resectable cholangiocarcinoma was analyzed. Heterogeneity between studies was assessed by means of the I2 statistic. We also performed subgroup analyses based on anatomical site of the tumor, geographic region, time of occurrence, and different levels of CA19-9. A random effects model was performed to express effect sizes as Hazard Ratio (HR) with 95% confidence intervals (CIs).ResultsA total of 60 original studies were eligible for inclusion, with a total of 15,031 patients with all sites, including 9014 males. The overall Hazard Ratio for all studies was 1.90 (95% CI 1.74–2.07, p < 0.001, Z = 14.59). Publication bias was suggested by the Begg’s test (p = 0.014 < 0.05), and the overall HR was 1.66 (95% CI 1.53–1.80, p < 0.001, Z = 12.027) after the trim-and-filling method. Subgroup analyses showed that intrahepatic cholangiocarcinoma (HR = 2.00, 95% CI 1.79–2.23), extrahepatic cholangiocarcinoma (HR = 1.65, 95% CI 1.49–1.82), hilar cholangiocarcinoma (HR = 1. 82, 95% CI 1.60–2.07), and distal cholangiocarcinoma (HR = 1.66, 95% CI 1.27–2.15) were predicted to be linked with prognosis. Elevated CA19-9 levels were associated with an increased risk of death.ConclusionsThis meta-analysis showed that elevated CA19-9 levels were correlated with a poor prognosis in cholangiocarcinoma. In future, more distal and hilar cholangiocarcinoma should be included in statistical studies to improve the accuracy of our conclusions.

Bayesan Model to Predict R Status After Neoadjuvant Therapy in Pancreatic Cancer.

To build a Bayesian approach-based model to predict the success of surgical exploration post-neoadjuvant treatment. Pancreatic cancer (PDAC) is best treated with radical surgery and chemotherapy, offering the greatest chance of survival. Surgery after neoadjuvant treatment (NAT) is indicated in the absence of progression, knowing the limits in accurately predicting resectability with traditional radiology. R Status being a pathological parameter, it can be assessed only after surgery. Patients successfully resected for histologically confirmed PDAC after NAT for BR and LA disease were included, with attention to the predictors of R status from the existing literature. The Bayesian logistic regression model was estimated for predicting the R1 status. The area under curve (AUC) of the average posterior probability of R1 was calculated and results were reported considering the 95% posterior credible intervals for the odds ratios, along with the probability of direction. The final model demonstrated a commendable AUC value of 0.72, indicating good performance. The likelihood of positive margins was associated with older age, higher ASA score, the presence of venous and/or arterial involvement at preoperative radiology, tumor location within the pancreatic body, a lack of tumor size reduction post-NAT, and the persistence of an elevated Ca19.9 value. A Bayesian approach using only preoperative items is firstly used with good performance to predict R Status in pancreatic cancer patients who underwent resection after neoadjuvant therapy.

Unveiling the prognostic role of blood inflammatory indexes in a retrospective cohort of patients undergoing liver resection for intrahepatic cholangiocarcinoma.

Systemic inflammation is relevant in intrahepatic cholangiocarcinoma (iCCA), but controversial results exist on the prognostic role of inflammatory indexes and their correlation with tumor microenvironment (TME). We aimed to explore the biological and prognostic values of these indexes. A retrospective cohort study involving iCCA patients who underwent hepatic resection between 2010-2021 was conducted. The neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and clinic-pathological factors were recorded. Immune-cell subpopulations, isolated from surgical specimens, were analyzed by flow cytometry. NLR and LMR cut-offs were calculated by X-Tile software. Linear regression, Kaplan-Meier, and Cox regression analyses were conducted. A total of 101 iCCA patients were considered. NLR ≥3.83 and LMR <2.28 correlated with worse survival. Patients were divided into groups: 67 (66.3%) in the low-risk and 34 (33.7%) in the high-risk (having at least one worse prognostic ratio). The 5-year overall survival was 49.8% and 18.9% for low- and high-risk groups, respectively (P=0.003). An elevated CA19.9 in the high-risk group gives 2.148 HR (95%CI:1.060-4.349) of mortality and 2.182 HR (95%CI:1.206-3.948) of disease recurrence. Flow cytometry analysis of 20 surgical specimens highlighted that NLR was associated with tumor-derived NLR (P=0.026) and LMR with tumor-infiltrating lymphocytes (P=0.002). In a subset of five high-risk vs five low-risk patients, T-cell evaluation showed a higher prevalence of CD4+ compared to CD8+ cells in the high-risk group (78.5% vs. 21.5%, P<0.0001). Conversely, low-risk patients demonstrated a noteworthy infiltration of CD8+ cells compared to the high-risk group (21.5% vs. 48.7%, P=0.037). The combination of blood inflammatory indexes determined two survival-risk profiles. The correlation between the blood scores and the iCCA microenvironment suggests a link between immune-cell infiltration and the risk group. These findings open the possibility of patient stratification with the chance to identify subgroups suitable for dedicated follow-up and targeted immuno-chemotherapy protocols.

Prognostic factors for intraductal papillary neoplasm of the bile duct following surgical resection: a systematic review and meta-analysis.

Intraductal papillary neoplasm of the bile duct (IPNB) is a biliary neoplasm characterized by intraductal papillary growth and varying degrees of malignant transformation. This study aimed to identify effective prognostic factors (PFs) for predicting the prognosis of IPNB after surgical resection, addressing the gap in the higher level evidence. We systematically searched databases from their inception to October 10, 2023. Data on 12 predetermined PFs were collected and subjected to a meta-analysis. Forest plots were used to summarize the findings. Fifteen studies with a total of 2311 patients were included. Among the PFs examined, extrahepatic tumor location (HR, 2.97; 95% CI 1.68-5.23), subclassification type 2 (HR, 2.62; 95% CI 1.45-4.76), R1 resection (HR, 2.47; 95% CI 1.73-3.51), elevated CA19-9 level (HR, 3.25; 95% CI 1.91-5.54), tumor multiplicity (HR, 2.65; 95% CI 1.40-5.02), and adjacent organ invasion (HR, 3.17; 95% CI 2.01-5.00) were associated with a poorer prognosis. Additionally, the combined HR values indicated that lymph node metastasis and poor tumor differentiation were linked to a worse prognosis, although both exhibited significant heterogeneity. Our study offers valuable insights for enhancing postoperative prognostication and treatment decision-making for IPNB patients with IPNB. These findings warrant further validation in future prospective studies.

Diagnostic Value of Osteopontin, Lymphocyte-to-Monocyte Ratio, and CA-125 in Ovarian Carcinoma Suspect

Osteopontin (OPN) is an important protein in cancer development and progressivity. Lymphocyte-to-Monocyte Ratio (LMR) as a systemic immunity and inflammatory indicator could be an ideal predictor biomarker because of its method’s simplicity and availability. Elevated CA-125 and OPN as well as decreased LMR were reported as signs of ovarian malignancy. Limited studies about OPN and LMR as diagnostic biomarkers, as well as various specificity and sensitivity of CA-125 intrigued the researcher to prove OPN, LMR, and CA-125 as diagnostic biomarkers for ovarian carcinoma. This study aimed to measure the diagnostic value of OPN, LMR, and CA-125 levels against histopathology results for ovarian carcinoma diagnosis. Eighty patients involved with suspected ovarian carcinoma who were referred to Dr. Kariadi Hospital, Semarang. Osteopontin and CA-125 levels were measured using ELISA, and LMR was calculated from absolute lymphocyte and monocyte counts using an automated hematology analyzer. The receiver operating characteristics curve was used to determine the cut-off and 2x2 table. The cut-off values for OPN, LMR, and CA-125 were 124 ng/mL, 3.7 and 45.4 U/mL, respectively. The sensitivity for OPN, LMR, and CA-125 was 67.24%, 62.07% and 60.34%. Specificity for OPN, LMR, and CA-125 were 68.18%, 54.55% and 59.09%. Osteopontin is the best parameter for determining the diagnosis of ovarian carcinoma but it is still not sufficient because OPN cut-off was still within the normal reference value.

The umblicus says it all

Abstract Introduction/Objective Umbilical nodules can be divided into benign and malignant. Malignant lesions of the umbilicus are very rare. They can arise from primary tumors or secondary to abdominal and pelvic malignancies. Literature review suggests that these umbilical lesions can present as primary tumor in 38% of the cases, endometriosis in 32%, and metastatic lesions in 30%. Umbilical metastasis is one of the main characteristic signs of extensive neoplastic disease and is known as Sister Mary Joseph’s nodule (SMJN). It is a very rare finding and the incidence of SMJN is 1- 3% in people diagnosed with intra-abdominal or pelvic malignancies. Methods/Case Report A 31-year-old male with no past medical history presented to the emergency room with 3 months history of umbilical nodule and 60 pounds weight loss. He experienced early satiety, abdominal pain, nausea and generalized fatigue. CT abdomen showed hepatomegaly with numerous hypoattenuating lesions throughout the liver with peripheral enhancement, and hypoattenuating mass within the pancreatic tail and body measuring approximately 2.1 x 5.8 cm that appears contiguous with hilar splenic lesion. CT chest showed multiple pulmonary metastases with prominent precarinal and subcarinal lymph nodes. Serologic tests revealed elevated Alpha fetoprotein, ALP, ALT, and CA19-9. Patient underwent umbilical nodule core biopsy and right liver core biopsy. Microscopic evaluation of the specimens revealed pancreatic acinic cell carcinoma with two different morphological variants. Umbilical nodule with glandular pattern and liver lesion with trabecular pattern. Immunohistochemical stains were performed with tumor cells positive for CK 7, Trypsin and BCL-10 and negative for Glypican 3, CK 20, AFP and CD56. The prognosis is poor, with an average survival time of about 19 months. After the diagnosis patient underwent chemotherapy. Results (if a Case Study enter NA) NA Conclusion Umbilical nodules can be diagnosed with careful clinical and histopathological evaluation. The prognosis of patients presenting with SMJN is generally poor as it is a sign of advanced malignancy. Sometimes it may be the first and only sign of an internal neoplasm. Therefore, this is an important differential diagnosis to consider.

Clinicopathological Characteristics of Small Cell Carcinoma of the Ovary, Hypercalcemic Type – a case Series

Abstract Introduction/Objective Small cell carcinoma of the ovary hypercalcemic type (SCCOHT) is a rare (&amp;lt;0.01%) and aggressive ovarian tumor primarily affecting young women (median of approximately 24 years), characterized by rapid growth, early metastasis, and association with hypercalcemia in two-thirds of cases. The diagnosis of SCCOHT is challenging due to its rarity and lack of specific clinical symptoms or biomarkers. Our study aims to delineate the clinicopathologic characteristics of SCCOHT based on our case series and add to the existing knowledge. Methods/Case Report A retrospective review of University of Pennsylvania Health system pathology database was conducted from 2012 to 2024. Our study identified four patients diagnosed with SCCOHT. Clinical information and histopathologic characteristics were reviewed. Results (if a Case Study enter NA) Among the four patients identified, the median age was 24 years, with a median tumor size of 14.5 cm, and all patients presented with weight loss, abdomen bloating, and elevated CA125 levels. Notably, two patients exhibited hypercalcemia, while one initially presented with normal calcium levels but developed hypercalcemia during disease recurrence. One patient maintained normal calcium levels throughout. Surgical intervention involved bilateral salpingo-oophorectomy in all cases, with pathological staging revealing two patients at pT1a, one at pT1c, and one at pT3c. Histopathological analysis consistently revealed similar morphology, including solid and cystic necrotic neoplasms with diffuse growth or nests/cords of undifferentiated small cells, which displaying vesicular chromatin and prominent nucleoli. Immunohistochemical staining demonstrated loss of BRG1 (SMARCA4) expression in two patients and diffuse positivity for WT1 in all patietns, while negative for cytokeratin, germ cell markers, and melanocytic markers. Genetic test revealed SMARCA4 mutation (p.E 717*, c.3169-1G&amp;gt;A) in one patient. Conclusion Small cell carcinoma of the ovary, hypercalcemic type, presents a diagnostic and therapeutic challenge due to its rarity and aggressive nature. Adequate treatment options are currently limited, highlighting the critical need for further research and development of targeted therapies in SCCOHT. Testing for mutations in the SMARCA4 gene is essential for accurate diagnosis of SCCOHT and may uncover new avenues for treatment and management strategies.

Sex-specific association between carbohydrate antigen 19–9 and incident type 2 diabetes

Carbohydrate antigen 19–9 (CA19-9) levels are associated with glycemic control, insulin resistance, and chronic complications in patients with type 2 diabetes (T2D). Women generally show higher CA19-9 levels despite a greater T2D prevalence in men. We evaluated the sex-specific longitudinal associations between CA19-9 levels and T2D incidence. Korean adults (n = 329,380) without previous cancer or T2D were categorized into four groups based on their CA19-9 levels. The study end point was the development of incident T2D during follow-up. Cox proportional hazards models were used to estimate hazard ratios (HR) according to CA19-9 levels. During a median follow-up of 6.1 years (3.3–9.3 years), the incidence rates of T2D were 9.9 per 1,000 person-years in men and 3.6 per 1,000 person-years in women. In the time-dependent analysis, adjusted HRs (95% confidence intervals) for incident T2D comparing CA19-9 levels of 10.0–19.9, 20.0–29.9, and ≥ 30 U/mL to the reference (< 10 U/mL) were 1.08 (1.04–1.13), 1.18 (1.07–1.30), and 1.64 (1.35–1.99), respectively, among men. However, this association was not observed in women. The association between CA19-9 category and incident T2D significantly differed by sex (Pinteraction = 0.006). Among young and middle-aged Korean adults, elevated CA19-9 levels were significantly associated with increased risk of type 2 diabetes in men but not in women. Elevated CA19-9 levels in men could be a useful marker for identifying individuals at high risk of developing T2D. Evaluation approaches for individuals with elevated CA19-9 levels should be sex-specific.

Poor Prognostic Factors in Long-Term Survivors of Resected Pancreatic Ductal Adenocarcinoma: An International, Multicenter Cohort Study.

To measure the rate of LTS in resected PDAC and determine the association between predictors of OS and LTS. Long-term survival (>5y, LTS) remains rare in pancreatic ductal adenocarcinoma (PDAC). Multiple predictors of overall survival (OS) are known but their association with LTS remains unclear. An international, multicenter retrospective study was conducted. Included were patients from 2012-2019 with resected PDAC. Excluded were those with metastases at diagnosis or resection, R2 resections, and 90-day mortality. Predictors of OS were identified using multivariable Cox regression and their prevalence in patients with LTS assessed. LTS was calculated by excluding patients with shorter follow-up and predictors of LTS were identified using multivariable logistic regression. 3,003 patients were included (27.4% received neoadjuvant chemotherapy). Elevated baseline CA19-9, high tumor grade, nodal disease, and perineural and lymphovascular invasion were negative independent predictors of OS, while receipt of adjuvant chemotherapy predicted improved OS (all P<0.05). LTS was observed in 220/2,436 patients (9.0%), of whom 198 (90%) harbored poor prognostic factors: elevated baseline CA19-9 (58.1%), poor tumor differentiation (51.0%), nodal disease (46.8%), and perineural invasion (76.0%). Of those without any of these four features, 50.0% achieved LTS as compared to 21.3%, 13.3%, 5.2%, and 3.5% in those with 1, 2, 3, or 4 features. This bi-national cohort demonstrates a true LTS rate of 9.0% in resected PDAC. Clinicians should remain aware that presence of poor prognostic factors does not preclude LTS.

Gall Bladder Perforation: An Unusual Cause of Elevated CA19-9 Levels

Gall Bladder Perforation: An Unusual Cause of Elevated CA19-9 Levels

Endoscopic Ultrasound in the Management of Intraductal Papillary and Mucinous Pancreatic Tumors: What is the Specificity?

Background: Pancreatic cysts, often symptomless, are more frequently detected with advanced imaging. Intraductal papillary mucinous neoplasms (IPMN) are the most common type, categorized into main-duct (MD-IPMN), branch-duct (BD-IPMN), and mixed forms, each with different risks of malignancy. Endoscopic ultrasound (EUS) aids precise diagnosis through detailed imaging and cyst fluid analysis, guiding personalized treatment and monitoring based on the patient's risk of malignancy. Method: This study was conducted at the EFD-HGE Unit of Ibn Sina Hospital in Rabat, from September 2015 to May 2024, were included all patients diagnosed with intraductal papillary mucinous neoplasms (IPMN) on imaging (MRI or CT scan). Epidemiological, clinical, biological and endoscopic ultrasound data were collected from EUS registries. Results: Out of 696 biliopancreatic EUS conducted, 44 patients were selected, representing a prevalence of 6.32%. The average age was 60.2 years (range 29-82 years), with a notable female predominance (M: 16, F: 28) (Sex Ratio = 0.57). The circumstances of discovery were incidental in 18 cases (40.9%), epigastric pain in 14 cases (31.8%), acute pancreatitis in 5 cases (11.4%), jaundice in 3 cases (6.8%), and abdominal pain in 4 cases (9.1%).biologically, cholestasis was observed in 10 cases (22.7%), elevated cytolytic enzymes in 5 cases (11.3%), and elevated Ca19-9 in 4 cases (9.1%).Endoscopic ultrasound provided details on tumor location, number, and size: predominantly in the pancreatic head in 21 cases (47.7%), body in 12 cases (27.2%), tail in 7 cases (15.9%), and multifocal in 4 cases (9.1%), with an average tumor size of 22.5 mm (range 19-57 mm). In 84.1% of cases (n = 37), there was communication solely with the main pancreatic duct (MPD), while in 15.9% (n = 7), there was communication with both the main pancreatic duct and secondary ducts, with Wirsung duct dilation in 15 cases (34%). Fine needle biopsy was performed in 23 cases (52%). ............

Ovarian-adnexal reporting and data system ultrasound evaluation and pathological characteristics of ovarian collision tumor.

Collision tumor are neoplasms, including two histologically distinct tumors that coexist in the same mass without histological admixture. The incidence of collision tumor is low and is rare clinically. To investigate ultrasound images and application of ovarian-adnexal reporting and data system (O-RADS) to evaluate the risk and pathological characteristics of ovarian collision tumor. This study retrospectively analyzed 17 cases of ovarian collision tumor diagnosed pathologically from January 2020 to December 2023. All clinical features, ultrasound images and histopathological features were collected and analyzed. The O-RADS score was used for classification. The O-RADS score was determined by two senior doctors in the gynecological ultrasound group. Lesions with O-RADS score of 1-3 were classified as benign tumors, and lesions with O-RADS score of 4 or 5 were classified as malignant tumors. There were 17 collision tumors detected in 16 of 6274 patients who underwent gynecological surgery. The average age of 17 women with ovarian collision tumor was 36.7 years (range 20-68 years), in whom, one occurred bilaterally and the rest occurred unilaterally. The average tumor diameter was 10 cm, of which three were 2-5 cm, 11 were 5-10 cm, and three were > 10 cm. Five (29.4%) tumors with O-RADS score 3 were endometriotic cysts with fibroma/serous cystadenoma, and unilocular or multilocular cysts contained a small number of parenchymal components. Eleven (64.7%) tumors had an O-RADS score of 4, including two in category 4A, six in category 4B, and three in category 4C; all of which were multilocular cystic tumors with solid components or multiple papillary components. One (5.9%) tumor had an O-RADS score of 5. This case was a solid mass, and a small amount of pelvic effusion was detected under ultrasound. The pathology was high-grade serous cystic cancer combined with cystic mature teratoma. There were nine (52.9%) tumors with elevated serum carbohydrate antigen (CA)125 and two (11.8%) with elevated serum CA19-9. Histological and pathological results showed that epithelial-cell-derived tumors combined with other tumors were the most common, which was different from previous results. The ultrasound images of ovarian collision tumor have certain specificity, but diagnosis by preoperative ultrasound is difficult. The combination of epithelial and mesenchymal cell tumors is one of the most common types of ovarian collision tumor. The O-RADS score of ovarian collision tumor is mostly ≥ 4, which can sensitively detect malignant tumors.

A nomogram predicting distant metastasis risk for gastric cancer patients with preoperative anemia: a multicenter retrospective study

BackgroundAnemia represents a well-established risk factor for patients diagnosed with gastric cancer, and is often associated with an unfavorable prognosis. In this context, the timely prediction of distant metastasis risk in patients with anemic gastric cancer assumes paramount importance.MethodsInformation of gastric cancer patients complicated with preoperative anemia in the First Affiliated Hospital of Sun Yat-sen University was collected. The cohort from the First Affiliated Hospital of Guangxi Medical University was used as an external validation set. A Nomogram was established based on the risk factors screened by univariate and multivariate logistic regression analyses.ResultsA total of 848 gastric cancer patients with preoperative anemia were enrolled. Pyloric obstruction, carcinoma antigen 125, T stage, N stage, tumor size, and preoperative weight loss were independent predictors of distant metastasis in gastric cancer patients with anemia (p < 0.05), based on which a nomogram was constructed. The accuracy, reliability and clinical value of the nomogram were evaluated by concordance index, receiver operating characteristic curve, decision curve analysis, calibration curve and showed good stability and clinical predictive value.ConclusionsPreoperative anemic gastric cancer patients, complicated with pyloric obstruction, elevated CA125, advanced T and N stage, larger tumor size, and preoperative weight loss, should be paid more attention to distant metastasis.

A striking elevation of CA19-9 after preoperative therapy negates prognostic benefit from radical surgery in resectable and borderline resectable pancreatic cancer

Identifying patients who can be spared nonbeneficial surgery is crucial, as pancreatic cancer surgery is highly invasive, with substantial negative effects on quality of life. The study objective was to investigate a useful indicator of patients who do not gain prognostic benefit from radical surgery after neoadjuvant therapy for resectable and borderline resectable pancreatic cancer. We compared factors among 609 patients with resectable or borderline resectable pancreatic cancer receiving neoadjuvant therapy during 2005-2019. Patients were divided into a poor-prognosis group (no surgery or postresection recurrence within a year) and a good-prognosis group (no recurrence or recurrence >1year after resection). Patients who experience a recurrence within a year of resection (poor-prognosis group) did no better than patients who received neoadjuvant therapy and progressed but never made it to surgery. The value of carbohydrate antigen 19-9 after neoadjuvant therapy was the most significant indicator to predict the poor prognosis group and the elevation of carbohydrate antigen 19-9 (>200 U/mL) identified only poor prognosis group with high specificity of 96.6%. The overall survival of patients with more than 200 of carbohydrate antigen 19-9 after neoadjuvant therapy was significantly very poor and their 2-year survival rate was only 41.4%. A striking elevation of carbohydrate antigen 19-9 after neoadjuvant therapy for resectable or borderline resectable pancreatic cancer is a good indicator of poor prognosis. Patients with carbohydrate antigen 19-9 >200 U/mL after neoadjuvant therapy should not undergo radical surgery.

An international multi-institutional validation of T1 sub-staging of intraductal papillary mucinous neoplasm-derived pancreatic cancer.

Intraductal papillary mucinous neoplasm (IPMN)-derived pancreatic ductal adenocarcinoma (PDAC) is resected at smaller sizes compared with its biologically distinct counterpart, pancreatic intraepithelial neoplasia (PanIN)-derived PDAC. Thus, experts proposed T1 sub-staging for IPMN-derived PDAC. However, this has never been validated. Consecutive upfront surgery patients with IPMN-derived PDAC from 5 international high-volume centers were classified by the proposed T1 sub-staging classification (T1a ≤0.5, T1b >0.5 and ≤1.0, and T1c >1.0 and ≤2.0 cm) using the invasive component size. Kaplan-Meier and log-rank tests were used to compare overall survival (OS). A multivariable Cox regression was used to determine hazard ratios (HRs) with confidence intervals (95% CIs). Among 747 patients, 69 (9.2%), 50 (6.7%), 99 (13.0%), and 531 patients (71.1%), comprised the T1a, T1b, T1c, and T2-4 subgroups, respectively. Increasing T-stage was associated with elevated CA19-9, poorer grade, nodal positivity, R1 margin, and tubular subtype. Median OS for T1a, T1b, T1c, and T2-4 were 159.0 (95% CI = 126.0 to NR), 128.8 (98.3 to NR), 77.6 (48.3 to 108.2), and 31.4 (27.5 to 37.7) months, respectively (P < .001). OS decreased with increasing T-stage for all pairwise comparisons (all P < .05). After risk adjustment, older than age 65, elevated CA19-9, T1b [HR = 2.55 (1.22 to 5.32)], T1c [HR = 3.04 (1.60 to 5.76)], and T2-4 [HR = 3.41 (1.89 to 6.17)] compared with T1a, nodal positivity, R1 margin, and no adjuvant chemotherapy were associated with worse OS. Disease recurrence was more common in T2-4 tumors (56.4%) compared with T1a (18.2%), T1b (23.9%), and T1c (36.1%, P < .001). T1 sub-staging of IPMN-derived PDAC is valid and has significant prognostic value. Advancing T1 sub-stage is associated with worse histopathology, survival, and recurrence. T1 sub-staging is recommended for future guidelines.

Ultrasonography Findings in Ovarian Hemangiomas: Report of Three Cases and Review of the Literature.

Ovarian hemangioma is a rare ovarian tumor. The imaging manifestations were rarely mentioned in previous literatures.One of the patients came to hospital with the complaints of an elevation of CA125. Another two patients found a mass in adnexa area accidentally. The oophorectomy procedures were performed and the pathological results of ovarian hemangioma were concluded. We summarized the ultrasound features of three cases retrospectively, of which could provide more information before operation to guide a management direction.A well-defined, regular-shape solid mass in ovary could be considered the possibility of hemangioma, especially when a richly vascularized tumor with prominent blood flow is detected on color Doppler sonography.

Comparison of Recurrence and Survival Between Patients With Pathological Stage I Epithelial Ovarian Cancer After Laparoscopic or Laparotomic Surgery: Retrospective Analysis of a Propensity-Matched Cohort

ObjectiveTo compare oncologic outcomes after laparoscopic or laparotomic surgery to treat epithelial ovarian carcinoma in FIGO Stage I. DesignRetrospective cohort study. SettingGynecological cancer ward in a tertiary hospital. ParticipantsA total of 85 patients with FIGO Stage I epithelial ovarian carcinoma who underwent laparoscopic staging surgery and 206 who underwent laparotomic staging surgery at West China Second Hospital, Sichuan University (Chengdu, China) between January 1, 2013 and December 31, 2019. InterventionsLaparoscopic surgery or laparotomic staging surgery. ResultsBefore propensity score-based matching, the laparotomy group showed higher prevalence of preoperative elevated CA125 level (48.5% vs 35.3%, p = .045) and tumors >15 cm (27.2% vs 5.9%, p <.001). Multivariate analysis associated higher body mass index with better overall survival (adjusted HR 0.83, 95% CI 0.70–0.99, p = .043). Among propensity score-matched patients (82 per group) who were matched to each other according to propensity scoring based on age, body mass index, CA125 level, largest tumor diameter, FIGO stage, history of abdominal surgery, and American Society of Anesthesiologists grade, the rate of progression-free survival at 5 years was similar between the laparoscopy group (87.1%, 95% CI 79.3–95.7%) and the laparotomy group (90.9%, 95% CI 84.7–97.6%, p = .524), as was the rate of overall survival at 5 years (93.9%, 95% CI 88.0–100.0% vs 94.7%, 95% CI 89.8–99.9%, p = .900). Regardless of whether patients were matched, the two groups showed similar rates of recurrence of 9–11% during follow-up lasting a median of 54.9 months. ConclusionsRates of recurrence and survival may be similar between laparoscopy or laparotomy to treat Stage I epithelial ovarian cancer. Since laparoscopy is associated with less bleeding and faster recovery, it may be a safe, effective alternative to laparotomy for appropriate patients.

Tubo-Ovarian Abscess with Highly Elevated CA125 Level is Misdiagnosed as Ovarian Cancer: A Case Report

Tubo-Ovarian Abscess with Highly Elevated CA125 Level is Misdiagnosed as Ovarian Cancer: A Case Report

Uterine tumors resembling ovarian sex cord tumors: A retrospective analysis of 7 cases from a single institution.

To investigate the clinicopathological features, diagnosis, surgical treatment and prognosis of uterine tumors similar to ovarian sex cord tumors (UTROSCT). The clinical data, surgical approach, histopathological, and immunohistochemical features of 7 cases of UTROSCTs were retrospectively reviewed and followed up. All 4 patients were premenopausal women. The most common clinical presentation was menorrhagia (n = 4) followed by postmenopausal lower abdominal mass (n = 2) and postmenopausal bleeding (n = 1). Gynecological ultrasonography suggested uterine fibroids in 4 cases, adenomyosis with uterine fibroids in 2 cases, and an intrauterine mass in 1 case. Pelvic MRI was performed preoperatively in only 2 cases, and both indicated uterine fibroid degeneration, including 1 patient with suspected malignancy. Preoperative serum tumor markers were measured in 6 patients, and only 1 patient had elevated CA125 levels, up to 158 U/mL. Total hysterectomy with bilateral adnexectomy or salpingectomy was the most common treatment pattern (n = 6). The tumors were located within the myometrium (n = 4), submucosa (n = 1), and isthmus to external cervical os (n = 1), with a range of 2 to 12 (mean = 8) cm. Edema and degeneration were observed in 2 cases, and necrosis in 1 case. Postoperative follow-up ranged from 31 to 82 (mean = 43) months. Unfortunately, 1 patient died at 54 months of follow-up without undergoing hysterectomy. The remaining 6 cases showed no tumor recurrence or metastasis after surgery. Histological examination revealed a tumor composed of epithelioid tumor-like cells arranged in cords, trabeculae, and nests. All 7 tumors showed expression of 2 sex cord differentiation markers. Furthermore, all tumors expressed the smooth muscle marker, while epithelial marker CK (4/7). endometrial stromal marker CD10(0/7). The Ki-67 proliferation index was found to be <5% (5/7). The option of total hysterectomy may be considered for women who do not have any fertility requirements. However, for young women who desire to maintain their reproductive capacity, surgery to preserve the uterus may be an alternative, although it necessitates careful postoperative monitoring. In terms of follow-up monitoring, MRI is more suitable than ultrasound. The diagnosis of UTROSCT heavily relies on histopathological examination and immunohistochemical analysis.
