Preoperative prediction of occult lymph node metastasis in patients with non-small cell lung cancer: a simple and widely applicable model.

Lymph node metastasis (LNM) is one of the most common pathways of metastasis in non-small cell lung cancer (NSCLC). Preoperative assessment of occult lymph node metastasis (OLNM) in NSCLC patients is beneficial for selecting appropriate treatment plans and improving patient prognosis. A total of 370 NSCLC patients were included in the study. Univariate and multivariate logistic regression analysis were used to screen potential risk factors for OLNM in preoperative NSCLC patients. And establish a nomogram for OLNM in NSCLC patients before surgery. Receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the established nomogram. Both univariate and multivariate logistic regression analyses suggested that multiple tumors, ERBB2 missense mutation, CA125 levels, CA153 levels, tumor site, tumor length, and serum ferritin are potential risk factors for OLNM in NSCLC patients. The constructed nomogram was evaluated, and the consistency index (C-index) and area under the ROC curve of the model were both 0.846. The calibration curve showed that the predicted values of the model had a high degree of fit with the actual observed values, and DCA suggested that the above indicators had good utility. The personalized scoring prediction model constructed based on multiple tumors, ERBB2 miss mutation, CA125 levels, CA153 levels, tumor site, tumor length, and serum ferritin can screen NSCLC patients who may have OLNM.

Synchronous primary ovarian tumours in postmenopausal women: A rare case report and literature review

The reported incidence of synchronous primary cancers of genital tract is 1-2%, among this synchronous primary ovarian tumour is rarest. Herein, a postmenopausal woman, who had previously undergone abdominal hysterectomy, presented with vague lower abdominal pain persisting for six months. A computed tomography scan confirmed the presence of an 8.1 x 8.2 cm cyst on her right ovary. Despite her CA125 levels being normal, she was scheduled for laparoscopic cystectomy. During the surgery, the left ovary was found to be enlarged, prompting bilateral salpingo-oophorectomy. Histological analysis revealed a serous cystadenoma in the left ovary and a mucinous cystadenoma in the right ovary.Most reported synchronous ovarian tumors are malignant, with only a few cases of benign synchronous ovarian tumors documented in the literature. Early diagnosis and reporting of such cases are crucial for improving our understanding of synchronous ovarian neoplasms, which can impact management strategies and help prevent complications.

Promising biomarker panel to monitor therapeutic efficacy of neoadjuvant chemotherapy in pancreatic cancer patients.

Neoadjuvant chemotherapy (NAC) can provide improved survival outcomes in pancreatic ductal adenocarcinoma (PDAC) patients who respond to treatment, but currently available biomarkers cannot reliably predict NAC response. This study aimed to determine the potential of a previously identified diagnostic and prognostic biomarker panel (i.e. Ca-125, S100A2, S100A4, Mesothelin and Ca19-9) for the monitoring of NAC-response in PDAC patients. This single-centre, retrospective study, utilised serum from NAC treated PDAC patients to determine the levels of biomarkers by Enzyme-Linked Immunosorbent Assay (ELISA). The percentage of the tumour bed occupied by viable carcinoma (PVC) was used to divide patients into good (PVC < 50%) and poor (PVC ≥ 50%) NAC-responders. Statistical analysis was performed to measure the ability of individual biomarkers and a biomarker panel in NAC treatment response and patient survival. Serum specimens from a total of 108 PDAC patients were assessed. Ca-125, Ca19-9 and S100A2 showed a significant positive correlation with PVC. Ca-125 demonstrated a superior ability to monitor NAC treatment response (Area under receiver operating curve (AUC): .6954) compared to the more widely used clinical biomarker, Ca19-9 (AUC: .6291). A panel of Ca-125 and Ca19-9 showed good ability to monitor NAC response in PDAC patients (AUC: .7349). Patients with high levels of both Ca-125 and Ca19-9 were shown to have the poorest overall survival (median overall survival: 17 vs. 30 months). A serum biomarker panel of Ca-125 and Ca19-9 could be used for effective clinical management of PDAC patients undergoing NAC treatment.

A Case of Porcelain Gallbladder Showing High Levels of CA19-9

The Role of HE4 in the Follow-Up of Advanced Ovarian, Fallopian Tube, and Primary Peritoneal Cancer—CEEGOG OX-01 Study

Background: Ovarian, fallopian tube, and primary peritoneal cancers often share clinical characteristics and are typically diagnosed at advanced stages due to nonspecific symptoms. The utility of tumor markers, particularly CA125 and HE4, in the diagnosis and follow-up of these cancers remains an area of active investigation. Objectives: The CEEGOG (Central and Eastern European Gynecologic Oncology Group) OX-01 study aimed to evaluate HE4’s role alongside CA125 in follow-up for advanced-stage ovarian, fallopian tube, and primary peritoneal cancers. It assessed the potential for detecting recurrence using marker elevation and imaging methods, examining the necessity of dynamic monitoring and current cut-off values’ accuracy for early relapse detection. Methods: In this multicenter prospective cohort study, 117 eligible patients with Stage III–IV cancers were included. Patients had elevated CA125 or HE4 at diagnosis and achieved complete remission after first-line treatment. HE4 and CA125 levels were monitored every 3–4 months in the first two years and every six months thereafter. CT scans were performed if markers exceeded set thresholds or increased by over 20%. Results: During a median follow-up of 13.7 months, 73% of patients relapsed. Median HE4 levels were significantly higher in relapsed patients. A 10 IU/mL increase from baseline in CA125 had a sensitivity of 83% and specificity of 93%, while a 15 pmol/L increase in HE4 had a sensitivity of 74% and specificity of 92% for predicting relapse up to three months before CT scan detection. Conclusions: The study found that dynamic changes in HE4 and CA125 levels, rather than predefined cut-off values, are crucial for early relapse detection. These markers may offer a significant lead time over imaging, potentially enabling earlier intervention. Further research is needed to validate these findings.

Neoadjuvant Treatment with Changes in Chemotherapy Regimens According to Carbohydrate Antigen 19-9 Level for Resectable/Borderline Resectable Pancreatic Ductal Adenocarcinoma.

The response of carbohydrate antigen (CA) 19-9 to neoadjuvant therapy (NAT) for pancreatic ductal adenocarcinoma (PDAC) may contribute to outcomes. This study aimed to investigate the effect of changes in NAT regimens based on CA19-9 level. This single-center retrospective study included patients with resectable/borderline resectable (R/BR)-PDAC undergoing NAT from 2008 to 2022. A CA19-9 level lower than 150 IU/mL after NAT was the criterion for resection. If the level did not decrease, the chemotherapy regimen was changed to satisfy the criterion. The patient cohort was divided into group A (satisfied criterion without changing chemotherapy), group B (did not receive chemotherapy change, could not satisfy the criterion), group C (received chemotherapy change, satisfied the criterion), and group D (received chemotherapy change, could not satisfy the criterion). The study cohort included 283 patients. After first-line chemotherapy, 112 (39.6%) patients did not satisfy the criterion (groups B [n = 64], C [n = 32], and D [n = 16]). Of the 283 patients, 48 (17%) received a chemotherapy change (groups C and D). The patients in groups C and D showed significantly better overall survival (OS, 35.9 months) than the group B patients (25.7 months) (P = 0.035). The OS of the group C patients (63.8 months) was similar to the OS of the group A patients (n = 171: 56.3 months; P = 0.430). Multivariate analysis of the patients in groups B, C, and D identified chemotherapy change as an independent prognostic factor for OS and progression-free survival. Changing the chemotherapy targeting the CA19-9 level can improve the outcome of R/BR-PDAC patients with poor biologic response to first-line NAT.

Lipid levels and insulin resistance markers in gastric cancer patients: diagnostic and prognostic significance.

Gastric cancer (GC) is a highly heterogeneous and aggressive malignant tumor that seriously affects the life safety of people all over the world. Its early manifestations are subtle. The present study aimed to investigate the clinical significance of serum lipid profiles, insulin resistance markers including the triglyceride-glucose (TyG) index and the atherosclerotic index (AI), in GC patients. A retrospective analysis encompassed 215 GC patients and 827 healthy individuals. The study results show that the total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein levels, and the TyG index of GC patients were significantly lower than those of the control group before and after propensity score matching analysis. In the GC group, the levels of CEA, CA199, CA125, and CA724 tumor markers were higher than those in the healthy control group. Patients in advanced stages exhibited lower serum levels of serum lipids and TyG index compared to those in early stages. ROC analysis revealed that the TyG index, CA125, and CA199 combination yielded the highest positive prediction rate for GC at 98.6%. TyG index is significantly associated with the risk of adverse reactions after chemotherapy (OR = 1.104, 95% CI 1.028-1.186, P < 0.01). Multiple tumor markers and the TyG index combined detection showed correlations with five adverse reactions caused by chemotherapy (r < 0.6, P < 0.05). Preoperative lipid profiles in the serum show a strong correlation with patients diagnosed with GC. Evaluating a combination of various serum lipids and cancer markers significantly improves diagnostic precision for GC and the ability to predict chemotherapy side effects.

A Case of CUP with Malignant Pleural Effusion: Overcoming Diagnostic and Therapeutic Hurdles with Chemotherapy

Introduction: Cancers of unknown primary (CUPs) present a diagnostic challenge as their origin is unidentified at diagnosis. Massive pleural effusion (MPE), indicative of lung metastasis in CUP, categorizes the condition into an unfavorable subset with a poor prognosis. Patients in this subset may exhibit a lower response to specific therapies. Case Presentation: A 62-year-old woman presented with cough, severe dyspnea, and MPE in the left lung. Thoracocentesis was performed, extracting 1,200 mL of hemorrhagic fluid, followed by the placement of an indwelling pleural catheter. The cytological examination of the pleural effusion indicated an adenocarcinoma, with immunohistochemistry revealing positive CK7 and negative CK20, Napsin A, and TTF-1. Additionally, elevated levels of Ca-125 (1,605 U/mL) and Ca 15-3 (242 U/mL) raised suspicion of gynecological malignancy. Thorax and abdominal CT scans, breast and thyroid ultrasounds showed no signs of malignancy, leading to the diagnosis of CUP. The patient’s performance status according to the Eastern Cooperative Oncology Group (ECOG) score was 4. Initial carboplatin 5 AUC and paclitaxel 175 mg/m2 administration resulted in improvement in performance status with ECOG score of 1, alleviation of dyspnea, reduction in pleural effusion 1 week after chemotherapy, with minimal effusion observed at 3 weeks, and Ca-125 levels decreased to 33.6 U/mL thereafter. Discussion: Empiric chemotherapy using carboplatin and paclitaxel is a feasible option for managing CUP with MPE mimicking gynecological malignancies with elevated Ca-125 and Ca 15-3 markers; initiating chemotherapy in poor performance status patients is beneficial with proper clinical judgment.

Longitudinal and time-to-event modeling for the survival of advanced pancreatic ductal adenocarcinoma patients.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers especially at advanced stage. In order to analyze the dynamics of potential prognostic biomarkers and further quantify their relationships with the overall survival (OS) of advanced PDAC patients, we herein developed a parametric time-to-event (TTE) model integrated with longitudinal submodels. Data from 104 patients receiving standard chemotherapies were retrospectively collected for model development, and other 54 patients were enrolled as external validation. The longitudinal submodels were developed with the time-course data of sum of longest diameters (SLD) of tumors, serum albumin (ALB) and body weight (BW) using nonlinear mixed effect models. The model-derived metrics including model parameters and individual predictions at different time points were further analyzed in the TTE model, together with other baseline information of patients. A linear growth-exponential shrinkage model was employed to describe the dynamics of SLD, while logistic models were used to fit the relationship of time prior to death with ALB and BW. The TTE model estimated the ALB and BW changes at the 9th week after chemotherapies as well as the baseline CA19-9 level that showed most significant impact on the OS, and the model-based simulations could provide individual survival rate predictions for patients with different prognostic factors. This study quantitatively demonstrates the importance of physical status and baseline disease for the OS of advanced PDAC patients, and highlights that timely nutrition support would be helpful to improve the prognosis.

Exploring the Diagnostic Challenges of Pseudotumoral Peritoneal Tuberculosis That Mimics Advanced Ovarian Cancer in Women: The Role of Laparoscopy in a Case Study

This case involves a 63-year-old multiparous woman with no significant medical history and no known exposure to tuberculosis. She presented with chronic abdominal pain and weight loss, anorexia, and subjective fevers. During the clinical examination, the patient was found to have ascites, bilateral pleural effusion, fever, and a general deterioration in her condition. Blood tests revealed normochromic normocytic anemia. The C-reactive protein was elevated, and the erythrocyte sedimentation rate was accelerated. Ferritin levels were raised. Her blood sugar, hepatic and renal functions were normals. The electrolyte panel showed no abnormalities. Serologies for hepatitis B, C, and HIV were negative, and the immunological profile was normal. The ascitic tap yielded a citrine-yellow fluid, and the cytochemical analysis indicated that the ascites were exudative. Analysis of the ascitic fluid revealed that the DNA test for Mycobacterium tuberculosis was negative, but the adenosine deaminase (ADA) level was elevated. Additionally, the CA125 level was significantly elevated, exceeding 600 UI/ml. A pelvic ultrasound identified a cystic pelvic mass with thick septations but without any solid tissue component, measuring 92x69 mm. The complementary CT (Computed Tomography) scan revealed enlarged ovaries, heterogeneous on the left, associated with a moderately abundant peritoneal effusion. The laparoscopic exploration revealed inflammatory peritoneal nodules, parietal adhesions, and serous ascites. Anatomopathology confirmed peritoneal tuberculosis. The peritoneal form, particularly in its pseudotumoral manifestation, can mimic ovarian cancer. Definitive diagnosis often requires invasive procedures.

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.

Development of an intraductal papillary mucinous neoplasm malignancy prediction scoring system.

Despite the presence of various guidelines, diagnosing malignant intraductal papillary mucinous neoplasm (IPMN) continues to pose challenges. Furthermore, although endoscopic ultrasonography (EUS) offers high-resolution images, it has not yet recognized as the primary tool for malignancy diagnosis. The study objective was to develop a simplified and user-friendly scoring system to improve the diagnostic accuracy of malignant IPMNs. Additionally, the utility of EUS and its effect on diagnostic accuracy were assessed. We retrospectively collected the clinical data on 160 cases of resected IPMN at Tokyo Medical and Dental University Hospital from January 2008 to December 2022. We examined clinical features, computed tomography (CT) and magnetic resonance imaging (MRI) findings, and EUS results if available. We then calculated the odds ratio of malignancy for these factors and developed an IPMN malignancy prediction (IMAP) scoring system. There were 89 (55.6%) cases of benign IPMNs and 71 (44.4%) of malignant IPMNs. Eight clinical and imaging findings, including age, diabetes mellitus status, jaundice, CA19-9 level, enhancing mural nodules ≥5mm, thickened wall, and main duct dilatation, were significantly associated with malignancy. The IMAP score was calculated by assigning 0 to 2 points to these factors based on the odds ratio. The area under the receiver operating characteristic curve for the IMAP score was 0.78 [95% confidence interval (CI): 0.71-0.85] based on CT/MRI alone and improved to 0.81 (95% CI: 0.74-0.87) when EUS was added. When the total exceeds 5 points, the positive predictive value becomes 100% (95% CI: 95.9-100). In conclusion, the IMAP scoring system has demonstrated promise as a clinically useful tool, offering both simplicity and sufficient accuracy. It holds potential as an important decision criterion for determining the treatment approach for IPMN. Additionally, EUS contributes to enhancing the diagnostic accuracy of the IMAP scoring system, thereby enabling more precise decision-making.

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.

Duodenal Adenocarcinoma Arising from Brunner’s Glands, A Rare Case Report

Abstract Introduction/Objective Malignancies arising from the Brunner’s glands in duodenum are exceedingly rare with very few cases reported in the literature. Here, we reported a case of duodenal adenocarcinoma of Brunner’s gland origin that obstructed duodenum and extended to involve the pancreatic head. Methods/Case Report A 48-year-old woman came to the Emergency Department of our hospital with epigastric and right upper quadrant abdominal pain. CT imaging demonstrated a heterogeneously enhancing 8.4 x 5.4 x 6 cm mass involving the duodenal lumen, wall, and pancreatic head. An endoscopic ultrasound showed a large fungating, infiltrative, and ulcerative mass in the second portion of the duodenum distal to the ampulla but not involving it. The pancreatic and common bile ducts were uninvolved. Her endoscopic ultrasound biopsy was positive for adenocarcinoma. CA19-9 levels were normal. The patient received chemotherapy with subsequent Whipple procedure. Gross examination revealed an exophytic, tan-white mass with the epicenter in the duodenal wall obstructing the duodenal lumen and extending to involve the pancreatic head inferiorly. The mass was predominantly solid with a few small mucus cysts. Light microscopy demonstrated moderately differentiated adenocarcinoma with prominent necrosis and inflammation. There are intestinal-type, gastric-type and indeterminate types of epithelia in the carcinoma. There are areas in the duodenal wall where a continuous transition from benign Brunner’s glands to dysplastic glands and then to adenocarcinoma is present. Neither adenoma in the overlying duodenal mucosa nor abnormalities in the pancreatic parenchyma is observed. Immunohistochemical stains showed that the neoplastic cells are positive for CAM 5.2, AE1/AE3, and CK7, while only patchy positivity with CK20 and CDX2. Taken together, a diagnosis of duodenal adenocarcinoma arising from Brunner’s glands was rendered. Results (if a Case Study enter NA) N/A Conclusion More cases are needed in order to establish standard treatment guidelines and determine prognostic factors.

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.

Nomograms predicting benefit after immunotherapy in oral bifidobacteria supplementation ICC patients: a retrospective study

PurposeThe objective of this study was to develop nomograms for predicting outcomes following immunotherapy in patients diagnosed with intrahepatic cholangiocarcinoma (ICC).Patients and methodsA retrospective analysis was conducted on data from 75 ICC patients who received immunotherapy at Jinling Hospital and Drum Hospital. The discriminative power, accuracy, and clinical applicability of the nomograms were assessed using the concordance index (C-index), calibration curve, and decision curve analysis (DCA). The predictive performance of the nomograms for overall survival (OS) and progression-free survival (PFS) was evaluated using the area under the receiver operating characteristic (ROC) curve. Kaplan-Meier curves were also generated for validation purposes.ResultsMultivariable analysis identified independent prognostic factors for OS, including CA19-9 levels, portal vein tumor thrombus (PVTT) grade, bifidobacteria administration, and surgery. The C-index of the nomogram for OS prediction was 0.722 (95% confidence interval [CI]: 0.661–0.783). Independent prognostic factors for PFS included CA19-9 levels, albumin, and bilirubin, with a C-index of 0.678 (95% CI: 0.612–0.743) for the nomogram predicting PFS. Calibration curves demonstrated strong concordance between predicted and observed outcomes, while DCA and Kaplan-Meier curves further supported the clinical utility of the nomogram.ConclusionThe nomogram developed in this study demonstrated favorable performance in predicting the prognosis of ICC patients undergoing immunotherapy. Additionally, our findings, for the first time, identified probiotics as a potential prognostic marker for immunotherapy. This prognostic model has the potential to enhance patient selection for immunotherapy and improve clinical decision-making.

Distal Pancreatectomy with and without Celiac Axis Resection for Adenocarcinoma: A Comparison in the Era of Neoadjuvant Therapy.

Distal pancreatectomy with celiac axis resection (DP-CAR) has been used for selected patients with pancreatic cancer infiltrating the celiac axis. We compared the short- and long-term outcomes between DP-CAR and distal pancreatectomy alone (DP) in patients receiving neoadjuvant therapy. Patients undergoing DP-CAR from 2013 to 2022 were retrospectively reviewed. Clinicopathologic features, post-operative morbidity, and survival outcomes were compared with patients undergoing DP after neoadjuvant chemotherapy. Twenty-two DP-CAR and thirty-four DP patients who underwent neoadjuvant chemotherapy were identified. There were no differences in comorbidities or CA19-9 levels. OR time was longer for DP-CAR (304 vs. 240 min, p = 0.007), but there was no difference in the transfusion rate (22.7% vs. 14.7%). Vascular reconstruction was more common in DP-CAR (18.2% vs. 0% arterial, p = 0.05; 40.9% vs. 12.5% venous, p = 0.04). There was no difference in morbidity or mortality between the two groups. Although there was a trend towards larger tumors in DP-CAR (5.1 cm vs. 3.8 cm, p = 0.057), the overall survival from the initiation of treatment (32 vs. 28 months, p = 0.43) and surgery (30 vs. 24 months, p = 0.43) were similar. DP-CAR is associated with similar survival and morbidity compared to DP patients requiring neoadjuvant chemotherapy and should be pursued in appropriately selected patients.

Development and validation of an early recurrence predictive model for intrahepatic cholangiocarcinoma based on a systematic review and meta-analysis of 17 cohorts

BackgroundIntrahepatic cholangiocarcinoma (ICC) is a rare malignant tumor with a high incidence of recurrence after surgery. This study aims to identify the early recurrence (ER) risk factors in ICC and develop an ER predictive model for ICC. MethodA computerized search was performed in Embase, Web of Science, Cochrane Library, and PubMed to identify studies focusing on the risk factors associated with ER in ICC. Based on the results of the meta-analysis, an ER predictive model was developed and validated using an external cohort of patients diagnosed with ICC through postoperative pathological examinations who received curative-intent surgery at West China Hospital of Sichuan University. ResultsA total of 4,534 ICC patients from 17 studies were included in the meta-analysis. The results indicated that gender, preoperative serum level of CA199, CEA, tumor size, tumor number, differentiation, macrovascular invasion, microvascular invasion, perineural invasion, lymph node metastasis, and AJCC T stage were ER risk factors for ICC. All risk factors were scored according to their weightings, and a risk predictive model was established. The area under the curve of the validation cohort was 0.902, indicating high predictive accuracy. Additionally, the calibration curve demonstrated that the predicted ER rate aligned well with the actual ER rate in the validation cohort. ConclusionThe predictive model accurately assesses the risk of ER in ICC patients undergoing surgical resection, providing valuable prognostic insights and guiding the tailoring of individualized treatment strategies to improve patient outcomes.

New definition of borderline resectable colorectal liver metastasis based on prognostic outcomes.

Although surgical resection is the curative treatment for colorectal liver metastases (CRLM), the efficacy of neoadjuvant chemotherapy (NAC) has been discussed due to recent remarkable advances in chemotherapy. The definition of borderline resectable (BR) is most important, where neoadjuvant chemotherapy should be administered. This study aimed to examine a new definition of BR CRLM based on the results of the treatment outcomes. This study included 127 patients who underwent liver resection for CRLM after exclusion of conversion cases between April 2010 and December 2023. Upfront resection was performed for synchronous and single liver metastasis or metachronous liver metastases. NAC was administered for multiple synchronous liver metastases. In order to find a new definition of BR, we examined the prognostic factors obtained from the treatment outcomes. CA19-9 level > 37.0 was the only prognostic factor in the upfront group [hazard ratio (HR) 2.386, 95% CI, 1.583-4.769; p = 0.049]. in the NAC group, a maximum tumor diameter ˃3 cm (HR 2.248, 95% CI 1.038-4,867, p = 0.040), CA19-9 level > 37.0 (HR 2.239, 95% CI 1.044-4.800, p = 0.038), and a right-sided primary tumor in the colon (HR 2.770, 95% CI 1.284-5.988, p = 0.009) were identified as significant prognostic factors. In cases of CRLM, patients with CA19-9 levels > 37.0, or CA19-9 level with < 37.0 but with a primary tumor in the right colon or a maximum tumor diameter of > 3cm can be defined as BR CRLM and should be treated with NAC.
