(A Clinicopathological Aspects of Resectable Pancreatic Neoplasm)

Aim Pancreatic cancer is one of the deadliest malignant neoplasms. As with many malignant neoplasms, survival rates depend on the histopathological type of cancer, its stage, tumor size, and treatment. In this study, we aimed to classify pancreatic cancer according to clinicopathological features and histological subtypes. Material and method The data of all adult patients diagnosed and treated for pancreatic neoplasm in our clinic were collected retrospectively from the hospital's computerized database and medical files. Patients were categorized according to their clinicopathological features. Chi-square test and Fisher's exact test were used for between-group comparisons, and t-test was used for independent samples for quantitative data. Data were expressed as mean ± SD for continuous variables and numbers and percentages for categorical variables. A value of p<0.05 was considered significant. Results The mean age of the patients was 60.5 years, 70.8% were male. There were five types of tumors defined histopathologically, and the most common diagnosis was adenocarcinoma (76.9%). The most common localization of the tumor was head and neck (44.4%). Whipple surgery was performed predominantly in 69.2% of patients, and distal pancreatectomy in 29.0%. Postoperative complications were observed in more than one third (34%) of the patients. The main complications were pancreatic cyst (16.3%). In the survival analysis performed with the Kaplan-Meier test, median survival of 30.5 months, and overall survival (OS) at 1.2 and 5 years were 67.8%, 40.5%, and 16.6%, respectively. Discussion However, survival analysis results were optimistic compared to population-based studies as all patients had resectable tumors.
