ABSTRACT
INTRODUCTION: Pancreatic adenocarcinoma (PAC) is diagnosed generally in patients older than 60 years old of age. It is rarely diagnosed in young adults. There is a dearth of data in younger population of patients with pancreatic ductal adenocarcinoma regarding epidemiology, prognosis, and outcome. The aim of our study of young PAC patients was to characterize the clinical features of this distinct young population who were treated in the National Institute of Oncology of Rabat. We selected the age of 45 years and under as the cutoff point in defining our patient population of interest. MATERIALS AND METHODS: A retrospective analysis of patients referred to the national institute of oncology of Rabat with PAC, who were ≤45 years at the date of histological diagnosis, between January 2005 and February 2010, was performed. Epidemiological, clinical, and pathological staging and therapeutic and follow-up data were extracted. RESULTS: The study included 32 cases of PAC. Male:female ratio was 2:1. It represents 17% of the entire population (N = 176) of PAC referred to the National Institute of Oncology over the time of study period. Mean age was 44-years-old (range: 28-45). Age range distribution was 1, 5, and 26 patients in age subgroups 20-29, 30-39, 40-45 years, respectively. Four patients (12.5%) had a smoking history and two patients (6%) had diabetes. None of the patients had a positive familial history of PAC or chronic pancreatitis. Tumor was located in head of pancreas in 75%, body in 12.5 %, and tail in 12,5%. Six patients (18.7%) had localized resectable disease and underwent resection with curative intent. Seven (21.8%) presented with locally advanced, inoperable disease. Two of them received only concurrent chemoradiation. Nineteen patients (59.3%) presented as AJCC Stage IV. Four (12.5%) of the six patients with resected tumors underwent adjuvant chemoradiation. Median overall survival was 50% at median follow-up of 6.8 months. CONCLUSION: This is the first reported study in our patient population of young patients with PAC. The data suggested that patients with younger age seem to have the same poor prognosis as the typical (older) patient population with PAC. No risk factors have been identified. However, this study is retrospective and more larger studies are needed in this young population.
