Background: Pancreatic adenocarcinoma (PA) is largely incurable, although recent progress has been made in the safety of surgery for PA and in adjuvant and palliative chemotherapy. The purpose of this study was to describe the management of PA in Ontario, Canada.
Methods:The Pathology Information Management System (PIMS), which uses electronic pathology reporting (E-path), was used to rapidly identify and recruit patients based on a pathologic diagnosis of PA between 2003 and 2006. Patients were mailed questionnaires for additional data.
Results:The patient participation rate was 26% (351 of 1325). Nonresponders were more likely to be older than 70 years (43% v. 28%, p < 0.001) and to have received treatment in nonacademic centres (53% v. 34%, p < 0.001). Fifty-four percent of responders underwent a potentially curative operation, and most (77%) were 70 years or younger (p = 0.03). Completed resections were documented in 83% of patients who underwent exploratory surgery with curative intent; 17% of patients had unresectable and/or metastatic disease at laparotomy. Of the completed resections, 24% were performed in nonacademic centres with a 32% positive margin rate; 76% were performed in academic centres with a 29% positive margin rate (p = 0.84). Resections with curative intent were less frequently aborted in academic centres (10% v. 33%, p < 0.001). Of the patients who responded to our questionnaire, 43% received chemotherapy and 7% participated in clinical trials.
Conclusion:Despite using PIMS and E-path, the response rate for this study was low (< 30%). Nonresponders were older and more commonly treated in nonacademic centres. Patients undergoing surgery in academic centres had higher resection rates. The rate of adjuvant and palliative chemotherapy was stage-dependent and low.Contexte : L'adénocarcinome du pancréas (AP) est en grande partie incurable, même si on a réalisé récemment des progrès au niveau de la sécurité de l'intervention chirurgicale contre l'AP et au niveau de la chimiothérapie d'appoint et palliative. Cette étude visait à décrire la prise en charge de l'AP en Ontario, au Canada. Résultats : Le taux de participation des patients a atteint 26 % (351 sur 1325). Les non-répondants étaient plus susceptibles d'avoir plus de 70 ans (43 % c. 28 %, p < 0,001) et d'avoir été traités dans des centres non universitaires (53 % c. 34 %, p < 0,001). Cinquante-quatre pour cent des répondants ont subi une intervention curative et la plupart (77 %) avaient 70 ans ou moins (p = 0,03). Les résections complétées ont été documentées chez 83 % des patients qui ont subi une intervention chirurgicale exploratoire à but curatif; 17 % des patients avaient une maladie irréséca-ble ou à métastases au moment de la laparotomie. Sur le total des résections complétées, 24 % ont été pratiquées dans des centres non universitaires et il y avait marge positive dans 32 % des cas, et 76 % ont été effectuées dans les centres universitaires et il y avait marge positive dans 29 % des cas (p = 0,84). Les résections à but curatif ont...
