Improvement in Treatment and Outcome of Pancreatic Ductal Adenocarcinoma in North China.
Summary of "Improvement in Treatment and Outcome of Pancreatic Ductal Adenocarcinoma in North China."
The incidence of pancreatic cancer has increased in China in the last decade, though efforts have been made in early detection and multimodality treatment. The aim of this study is to describe the decade-based development in early diagnosis and treatment modalities, as well as outcome for patients with pancreatic ductal adenocarcinoma (PDAC) in a high-volume facility.
All the PDAC patients underwent surgery between 1991 and 2009 and were selected from the database of TianJin Cancer Institute and Hospital. Decade-based changes in early diagnosis, treatment modalities, and outcome of the patients were retrospectively analyzed.
Of the 565 patients with PDAC, patients in this decade (n = 460) had better overall survival than those in the last decade (n = 105), median survival was 10 months and 3 months, respectively. Patients in this decade had significantly improved in (P < 0.001) 2-year (14.7%) and 5-year survival rates (3.5%) as compared to those in the last decade (6.7% and 3.4%, respectively). Patients with metastasis at diagnosis in the last decade and this decade were 54% and 26% (P < 0.001), respectively. More patients in this decade had underwent R0/R1 resection (33% vs 20%, P = 0.010), chemotherapy (37% vs 12%, P < 0.001), and radical resection (34% vs 21%, P = 0.014) than those in the last decade.
Patients operated on for PDAC in this decade had a better outcome than those in the last decade. Early detection, improved resection margin, and development in multimodality treatment contribute to this improvement.

Medical and Biotech [MESH] Definitions
Carcinoma that arises from the PANCREATIC DUCTS. It accounts for the majority of cancers derived from the PANCREAS.
A true cyst of the PANCREAS, distinguished from the much more common PANCREATIC PSEUDOCYST by possessing a lining of mucous EPITHELIUM. Pancreatic cysts are categorized as congenital, retention, neoplastic, parasitic, enterogenous, or dermoid. Congenital cysts occur more frequently as solitary cysts but may be multiple. Retention cysts are gross enlargements of PANCREATIC DUCTS secondary to ductal obstruction. (From Bockus Gastroenterology, 4th ed, p4145)
A precursor of noradrenaline that is used in the treatment of parkinsonism. The racemic form (DL-threo-3,4-dihydroxyphenylserine) has also been used, and has been investigated in the treatment of orthostatic hypotension. There is a deficit of noradrenaline as well as of dopamine in Parkinson's disease and it has been proposed that this underlies the sudden transient freezing seen usually in advanced disease. Administration of DL-threo-3,4-dihydroxyphenylserine has been claimed to result in an improvement in this phenomenon but controlled studies have failed to demonstrate improvement.
