Early diagnosis of pancreatic cancer (PC) can improve patients’ prognosis. We aimed to investigate the utility of endoscopic ultrasonography (EUS) for the early diagnosis of PC. This study included 64 patients with PC at an early stage treated at Onomichi General Hospital between January 2007 and January 2020. Diagnostic procedures included contrast computed tomography (CT), magnetic resonance cholangiopancreatography, EUS fine-needle aspiration, and endoscopic retrograde cholangiopancreatography (ERCP) for pancreatic juice cytology. The mean age was 71.3 years. In all, 32 patients were stage 0, and 32 were stage I. As for image findings, the main pancreatic duct (MPD) stenosis was detected in several cases, although CT and MRCP seldom detected tumors. EUS had a high detection rate for stage 0 tumor lesions. The median observation period was 3.9 years. In cases with stage 0, the 1 year and 5 year survival rates were 100% and 78.9%, respectively. In cases with stage I, the 1 year and 5 year survival rates were 96.4% and 66.7%, respectively. EUS has the highest sensitivity among all imaging modalities for detecting small pancreatic tumors. Cases with MPD dilation or stenosis, especially with tumors that cannot be identified on CT and MRI, should have EUS performed. In some cases, EUS was not able to detect any tumor lesions, and ERCP-based pancreatic juice cytology should be useful for pathological diagnosis.

Pancreatic cancer has the poorest prognosis among all cancers, and early diagnosis is essential for improving the prognosis. Along with radiologic modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), endoscopic modalities play an important role in the diagnosis of pancreatic cancer. This review evaluates the roles of two of those modalities, endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP), in the diagnosis of pancreatic cancer. EUS can detect pancreatic cancer with higher sensitivity and has excellent sensitivity for the diagnosis of small pancreatic cancer that cannot be detected by other imaging modalities. EUS may be useful for the surveillance of pancreatic cancer in high-risk individuals. Contrast-enhanced EUS and EUS elastography are also useful for differentiating solid pancreatic tumors. In addition, EUS-guided fine needle aspiration shows excellent sensitivity and specificity, even for small pancreatic cancer, and is an essential examination method for the definitive pathological diagnosis and treatment decision strategy. On the other hand, ERCP is invasive and performed less frequently for the purpose of diagnosing pancreatic cancer. However, ERCP is essential in cases that require evaluation of pancreatic duct stricture that may be early pancreatic cancer or those that require differentiation from focal autoimmune pancreatitis.

ObjectiveThe aim of the study was to investigate whether omentectomy (OMT) is necessary in the operation for apparently early stage malignant ovarian germ cell tumors (MOGCTs).Methods and MaterialsSearching medical records database of Sun Yat-sen University Cancer Center from January 1, 1966, to November 30, 2015, patients with MOGCTs were identified and their age, year of diagnosis, tumor grade, histologic subtype, International Federation of Gynecology and Obstetrics stage, nodal findings, gross observation of omentum, and performance of OMT were assessed. Overall survivals of patients with or without OMT were compared using Kaplan-Meier survival curves.ResultsA total of 223 MOGCT cases with clinically early stage (stage I and II) disease and with the 3 common histological subtypes of MOGCT were obtained, which include yolk sac tumor (YST), dysgerminoma (DSG), and immature teratoma (IMT). There were 192 stage I cases and 31 stage II cases. Fifty-four patients were diagnosed with YST, 61 with DSG, and 108 with IMT. Omentectomy was performed as part of the initial surgery in 74.0% patients (165/223) and was omitted in 26.0% patients (58/223). Chemotherapy was administered in 88.3% (197/223) of all patients. The median follow-up was 82.0 months. The 10-year overall survival rates of the patients with and without OMT were 90.5% and 98.1%, respectively (P = 0.156). Regarding different stages or histological subtypes, the 10-year survival rates of the 2 groups were 92.0% versus 97.9% (P = 0.324, stage I), 83.2% versus 100% (P = 0.351, stage II), 89.2% versus 100% (P = 0.303, YST), 94.1% versus 100% (P = 0.470, DSG), and 89.4% versus 96.0% (P = 0.405, IMT), respectively.ConclusionsIn conclusion, OMT in patients with clinically early stage MOGCT may not improve patient survival and may be omitted.

This study aimed to assess whether contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS), compared to multidetector-row computed tomography (MDCT) and magnetic resonance imaging (MRI), is useful for early diagnosis of small pancreatic cancer (PC). Between March 2010 and June 2018, all three imaging modalities and surgery were performed for patients with a pancreatic solid lesion measuring ≤20 mm; diagnostic ability was compared among modalities. Fifty-one of 60 patients were diagnosed with PC (PC size in 41 patients: 11–20 mm; 10 patients: ≤10 mm). The sensitivity, specificity, and accuracy of CH-EUS, MDCT, and MRI for PC (11–20 mm) detection were 95%/83%/94%, 78%/83%/79%, and 73%/33%/68%, respectively. The diagnostic ability of CH-EUS was significantly superior compared with MDCT and MRI (p = 0.002 and p = 0.007, respectively). The sensitivity, specificity, and accuracy of CH-EUS, MDCT, and MRI for PC (≤10 mm) detection were 70%/100%/77%, 20%/100%/38%, and 50%/100%/62%, respectively. The diagnostic ability of CH-EUS tended to be superior to that of MDCT (p = 0.025). The sensitivity of MDCT for PC (≤10 mm) detection was significantly lower than that for PC (11–20 mm) detection (20% vs. 78%; p = 0.001). CH-EUS, compared to MDCT and MRI, is useful for diagnosing small PCs.

The Impact

e15052 Background: Pancreatic resection is the only known curative option for pancreatic adenocarcinoma. Resection has been previously reported to be underutilized in patients with early stage disease. To develop a better understanding of this issue and control for treatment selection factors, we examined the relationship between geographic area resection rates and survival in patients with stage I/II pancreatic cancer. Methods: We queried Surveillance, Epidemiology, and End Results (SEER) data for patients with stage I/II cancer of the pancreatic head diagnosed from 2004-2009. We excluded patients with less than 3mo survival. Resection rates were calculated within Health Service Areas (HSAs) across all 18 SEER regions. Resection rate was defined as the number of patients who had an operation divided by the total number diagnosed with early stage pancreatic cancer. Multivariate Cox regression was used to estimate the overall survival effect of HSA rates while controlling for age, gender, marital status, poverty level, education, and AJCC stage. Results: 8,323 patients with stage I (n=1,454) and stage II (n=6,869) disease were analyzed. Pancreatectomy was performed in 476 patients (32.7%) with stage I disease and 3,846 (56.0%) with stage II disease. HSA resection rates were arranged into five groups (quintiles) which ranged from 42.7 to 65.7% (Table). Across the quintiles, median overall survival increased from 11 to 14 months, suggesting a positive association with resection rate. Multivariate analysis revealed that for every 10.00% increase in resection rate, the risk of overall death decreased by 5.26% (p<0.001). Conclusions: Patients with early stage pancreatic cancer who live in areas with higher resection rates have longer average survival times. Because geography should not influence treatment response, we conclude that efforts to raise resection rates should increase survival times in patients for whom there is uncertainty about the risk/benefits of resection.

Ct Finding

Pancreatic invasive ductal adenocarcinoma (PDAC) has a poor prognosis, and the detection of PDAC during the early stage is thought to improve prognosis. In this study, we retrospectively investigated pancreatic morphological abnormalities that lead to the early diagnosis of PDAC with computed tomography (CT) imaging. In total, 41 out of 308 patients diagnosed with pancreatic cancer between 2011 and 2017 in our institution were enrolled. As a control group for the group with pancreatic cancer, 4277 patients without pancreato-biliary diseases were enrolled. We retrospectively reviewed and analyzed the clinical data including patient characteristics, the clinical course and preoperative CT imaging with pancreatic morphological features. Out of 41 patients, 24 patients (58.5%) showed local K-shaped constriction of the pancreatic parenchyma “K-sign” on preoperative CT images. Eight patients (19.5%) showed localized fatty change. Out of 4277 control patients, seven patients (0.16%) showed K-sign. “K-sign” may be used for the early diagnosis of PDAC by CT imaging.
