    Abstract

    Background. Pancreatic adenocarcinoma is an aggressive cancer with a poor prognosis and increasing global incidence. Early diagnosis is challenging, as it is often detected at advanced stages. Imaging, particularly contrast-enhanced Multispiral Computed Tomography, plays a crucial role in diagnosing, assessing resectability, and monitoring treatment response. This study aimed to analyze Pancreatic adenocarcinoma characteristics, including tumor location, metastasis, resectability, and postoperative outcomes, using Multispiral Computed Tomography. Methods A retrospective review of 216 Pancreatic adenocarcinoma cases from 20222024 was conducted. All patients underwent bolus contrast-enhanced Multispiral Computed Tomography, and diagnoses were confirmed by histology. Key patient parameters analyzed included age, gender, tumor location, metastases, and surgical outcomes. Results The group comprised 50.9% women and 49.1% men. The majority of tumors were located in the pancreas head (72.2%), followed by the body (13.9%), tail (3.7%), and multiple sites (10.2%) (p<0.05). Metastases were observed in 50% of patients, with the liver being the most common site (p<0.05). Radical surgery was performed in 41 patients (19%), while 66 patients (30.5%) underwent palliative procedures. The mean life expectancy among deceased patients was without surgery 110 days, after radical resections 247 days, after palliative interventions 118 days. Conclusion Pancreatic adenocarcinoma remains a highly fatal disease, particularly at advanced stages. Metastasis significantly worsens prognosis, reducing survival rates. Tumor location influences prognosis, with body and tail tumors having better outcomes. Surgery improves survival, and early diagnosis is critical. Contrast-enhanced Computed Tomography is essential for evaluating pancreatic tumors but should be complemented with other diagnostic methods for enhanced accuracy.

    Abstract

    : the aim of this study is to analyze the current advances of CT perfusion in the diagnosis of liver disease. Liver fibrosis is a characteristic feature of chronic liver disease and is confirmed by liver biopsy, which is an invasive method. Morphologic parameters of cirrhosis are evaluated by conventional imaging techniques such as ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI). Additional studies of new imaging modalities are needed for earlier diagnosis, surveillance and accurate treatment, CT perfusion has several advantages by examining the arterial and venous blood flow of the liver, which gives a more complete picture of early functional changes in the liver. Despite the advantages of this method, the results of postprocessing in different stages of fibrosis and etiology of its development are not fully understood.

    Abstract

    Background. The sensitivity and specificity of multislice computed tomography is of great importance in the detection of gastric and esophageal cancer, and also expands the possibilities of preoperative staging using computed tomography.

    Materials and methods. A retrospective study at the A.N. Syzganov National Scientific Center of Surgery from 2022 to 2024, included 121 patients: 48 females (39.6%), 73 males (60.3%), with an average age of 60 years. Sensitivity, specificity were calculated to assess diagnostic accuracy. Esophageal and gastric cancer staging via computed tomography was done using the TNM classification and compared with esophagogastroduodenoscopy, pathohistological examination results.

    Results. The sensitivity of computed tomography was 96.49%, the specificity was 85.71%. Esophagogastroduodenoscopy showed a sensitivity of 79.75%, specificity of 95.24%.

    Conclusion. Computed tomography is highly informative, sensitive in detecting esophageal and gastric cancer, with superior diagnostic accuracy compared to esophagogastroduodenoscopy. Given the detection of esophageal and gastric cancer at T2 and T3 stages, along with the presence of distant metastases in some patients, implementing protocols for early diagnosis is advisable.

  • PANCREATIC CANCER DIAGNOSIS OVERCOMING BIAS AND ERRORS (CASE SERIES) (Issue № 2, 2024)

    Abstract

    Diagnosing malignant pancreatic neoplasms presents a challenging task fraught with the possibility of diagnostic errors due to similarities with other pathologies such as pancreatitis, neuroendocrine tumors, and cystic formations. The key diagnostic method is contrast-enhanced multi-detector computed tomography, yet even this method has certain limitations that may affect diagnostic accuracy.Through the analysis of clinical cases, typical errors accompanied by visual characteristics that can be misleading in differential diagnosis have been identified. Hypodensity and tissue structure alterations, changes in ducts, or mass effect may be common features of both cancer and pancreatitis. Comparing visual signs with the clinical picture and employing additional methods aids in reaching a more precise diagnosis.It is important to note that rare pathologies such as serous oligocystic adenoma and intraductal papillary mucinous neoplasm may also pose additional challenges for accurate diagnosis due to their unusual characteristics on computed tomography scans.The conclusions of the study underscore the importance of a multimodal approach to diagnosing malignant pancreatic neoplasms, including the use of various imaging methods to ensure an accurate diagnosis and the selection of the most appropriate treatment strategy
