432 Background: Guidelines recommend pancreatic protocol CT scan (CT) for staging vascular involvement in patients with pancreatic cancer (PC). While endoscopic ultrasound (EUS) has been demonstrated to be effective in venous staging of PC, its role when combined with CT is poorly defined. We evaluated the utility of EUS in addition to CT in staging PC. We hypothesized that EUS complements CT in identifying SMV/PV tumor involvement as measured by the requirement for vein resection. Methods: We reviewed our database of patients with borderline resectable PC who went to surgery with curative intent. Inclusion criteria were pre-operative staging with CT scan, EUS, PET scan, and CA 19-9 levels, as well as completion of neoadjuvant chemotherapy and radiation. Results: We identified 62 patients with 74% of tumors in the pancreatic head. 97% of resections were R0. The average age was 65 ± 9 years; 60% were male. Patients were classified as borderline resectable by EUS alone in 29%, CT alone in 23%, and both modalities in 48% of patients, respectively. 34 patients required vein resection; EUS identified 88% of these patients pre-operatively while CT identified 68%. EUS identified 11 patients who required vein resection that CT did not identify while CT identified 4 patients that EUS did not identify. EUS had higher sensitivity and specificity than CT in identifying patients requiring venous resection (Table). On multivariate logistic regression analysis, EUS was predictive of vein resection (P < 0.02) but CT scan findings, PET scan findings, tumor size, and CA19-9 values were not predictive (each P > 0.1). In margin negative resected patients, median survival was longer when both CT and EUS identified borderline status compared to only 1 modality (43 vs 23 months, P < 0.05). Conclusions: EUS complemented CT in identifying patients with borderline resectable PC requiring vein resection- 29% of patients were identified with EUS alone. This observation supports the use of EUS in addition to CT scan for the vascular staging of patients with PC. [Table: see text]

Background: pancreatic cancer is one of the most lethal malignancies and a leading cause of cancer-related death worldwide. The only chance to improve the long-term outcomes of patients with pancreatic cancer is surgery with radical intent. Methods: in the present paper, we aim to describe a case series of 9 patients submitted to radical surgery for borderline resectable pancreatic cancer. Results: in all cases, negative resection margins were achieved. The types of venous resection consisted of tangential portal vein resection in four cases, circumferential portal vein resection with direct reanastomosis in one case and circumferential resection with graft placement in another four cases; postoperatively, one patient developed a vascular surgery-related complication consisting of graft thrombosis and thus necessitated prolonged anticoagulant therapy. Conclusions: extended venous resections can be a safe and efficient way to maximize the benefits of radical surgery in locally advanced, borderline resectable pancreatic cancer.

Extension of pancreatic adenocarcinoma into adjacent vasculature often necessitates resection of the portal vein (PV) and or superior mesenteric vein (SMV) during pancreaticoduodenectomy (PD). Our study describes the surgical technique and results of PV/SMV resection in pancreatic adenocarcinoma patients. Between January 2008 and October 2013, 252 patients underwent PD for pancreatic malignancy. A total of 42 PV/SMV resections were performed (28 men, 14 women). Patients were categorized into 2 groups according to the degree of invasion into the portal vein wall: Group A (n = 16), extended compression of the portal vein wall by the surrounding carcinoma without true invasion, and Group B (n = 26), true invasion including intramural and transmural invasion. Morbidity of the 42 patients was 35%; there was no operative mortality, and overall 1-, 3-, and 5-year survival rates were 60%, 21%, and 12%, respectively. No differences in tumor size, margin positivity, nodal positivity, or survival rates were observed between groups. Resection of the PV/SMV is safe and does not increase morbidity or mortality. Tumor involvement of the PV/SMV is not associated with histopathologic signs that are predictive of a poor prognosis. The “artery first” approach should be considered as a means to facilitate safe venous resection and reconstruction.

Borderline Resectable Pancreatic Cancer

494 Background: The management of borderline resectable pancreatic cancer (BRPC) remains unsettled and the predictors of outcome are uncertain. We evaluated the role of neoadjuvant therapy (nRx) and outcomes in patients with BRPC. Methods: We conducted a retrospective cohort study of consecutive patients with BRPC who received nRx and were followed at the Cleveland Clinic. A histopathologic diagnosis of pancreatic carcinoma was required. Tumor anatomy was assessed by contrast-enhanced cross-sectional imaging (CT or MRI), and BRPC was defined as a tumor-vessel wall interface involving one or more of: celiac artery, superior mesenteric artery, common hepatic artery, main portal vein, superior mesenteric vein; making margin-negative resection unlikely. Baseline laparoscopy was performed to rule out occult metastatic disease. Chemotherapy (CT), radiation (RT), surgery details, and pathologic and survival outcomes were evaluated. Hazard ratios (HR) with 95% confidence intervals (CI) and 2-sided p-values are presented. Results: The study population comprised 79 patients from 2009 to 2014. Median age was 64 years; 52% were male; 85% were Caucasian. Pancreatic head/neck were the primary site in 81%; body/tail in 19%. Vascular involvement included arterial in 32 (41%), and venous in 65 (82%) patients. nRx included RT in all patients; 77 (97%) received CT; gemcitabine (n = 50, 63%) was the most common agent. After CT/RT, 36 (46%) patients had unresectable/inoperable disease: 29 (37%) for anatomic reasons, 4 (5%) for physiologic reasons, and 3 (4%) for both. Surgical resection was performed in 43 (54%) patients; 38 (88%) had negative margins; 30 (70%) had negative nodes; 32 (74%) received adjuvant CT. There were no statistically significant predictors of resection. After median follow-up of 27 mths, there have been 45 deaths (57%); median overall survival (mOS) is 23.5 mths (95% CI: 16-28 mths). Only cancer resection was associated with survival (mOS, resected: not reached; mOS, not resected: 12.8 mths; HR: 0.30, 95% CI: 0.16-0.56, p = 0.0002). Conclusions: Surgical resection, if feasible, of BRPC is associated with improved OS. Strategies to improve the odds of resection should be evaluated in prospective studies.

Introduction: The purpose of this paper is to study the type, the clinical presentation, and the best diagnostic methods for pleural solitary fibrous tumors (PSFTs), as well as to evaluate which is the most appropriate treatment, especially as PSFTs represent a rare occurrence in the thoracic pathology. Material and Method: A retrospective study was conducted on a group of 45 patients submitted to surgery between January 2015 and December 2019. In most cases, the diagnosis was established through imaging studies—thoracic computed tomography (CT) scan with or without contrast—but also using magnetic resonance imaging (MRI) or positron emission tomography (PET) scans when data from CT scans were scarce. All patients were submitted to surgery with curative intent. Results: Most patients included in this study were asymptomatic, with this pathology being more common in patients over 60 years of age, and more common in women. The occurrence of malignant PSFT in our study was 17.77% (8 cases). All cases were submitted to surgery with curative intent, with a single case developing further recurrence. In order to achieve complete resection en bloc resection of the tumor with the chest wall, resection was performed in two cases, while lower lobectomy, pneumectomy, and hemidiaphragm resection, respectively, were needed in each case. Postoperative mortality was null. Conclusion: Thoracic CT scan remains the most important imagistic investigation in diagnosing. MRI is superior to thoracic CT, especially in cases that involved the larger blood vessels within the thorax, spinal column, or diaphragm. Complete surgical resection is the gold standard in treatment of PSFT, and the prognosis in benign cases is very good.

Background: Pancreatic cancer is one of the most aggressive neoplastic processes. Inspite of progress in the diagnosis and treatment of malignancies, the resectability and survival rates for pancreatic cancer are very poor. This study aims to determine the accuracy of computerised tomography in assessing the resectability of carcinoma pancreas.Methods: 66 patients with carcinoma pancreas, who were judged fit for surgery were studied. All cases had undergone preoperative contrast enhanced triphasic computed tomography (CT) for assessing the resectability. Radiological data was compared with per operative findings for assessments regarding vascular invasion and resectability.Results: Of the 66 cases, resectability reported by CT was 59 (89.4%). The rest of 7 (10.6%) cases were reported as unresectable. Per operatively vascular involvement was found in 14 (21.2%) cases and with no vascular invasion in 52 (78.8%) cases. All the unresectable cases reported in CT (7 cases) turned out to be unresectable. Out of 59 cases reported as resectable, 43 (65.2%) cases under went Whipples procedure, while rest of the 23 (34.8%) cases underwent palliative procedures. Out of these 23 cases, 14 (21.2%) cases were unresectable due to vascular involvement.Conclusions: The study has shown that CT does assess the operability in carcinoma pancreas, assessing mainly unresectability though less effective in assessing resectability. The role of endoscopic ultrasound and laparoscopic ultrasound in aiding CT in further assessment of resectable and borderline resectable cases are to be considered for further research.
