Seven cases of cystic neoplasms of the pancreas (5 cystadenomata and 2 cystadenocarcinomata) are reported. While cystadenomata were localized in the tail of pancreas, cystadenocarcinomata were localized in the head. Only one case was asymptomatic and evidenced in the course of other type of surgery. Preoperative diagnosis of cystadenoma was assessed only in(More)
We analyzed the pattern of failure and clinicopathologic factors influencing the disease-free survival of 78 patients who died after macroscopic curative resection for pancreatic cancer. Local recurrence was a component of failure in 56 patients (71.8%) and hepatic recurrence in 48 (61.5%), both accounting for 97% of the total recurrence rate. About 95% of(More)
BACKGROUND Carcinoma arising from the body and tail of the pancreas is less frequent than pancreatic head cancer, and its prognosis is known to be worse. This aggressive behavior is reported by few large clinical studies. STUDY DESIGN We retrospectively reviewed our 24 years experience on adenocarcinoma of the body and tail of the pancreas and analyzed(More)
OBJECTIVES Serous cystic neoplasm (SCN) is a cystic neoplasm of the pancreas whose natural history is poorly known. The purpose of the study was to attempt to describe the natural history of SCN, including the specific mortality. DESIGN Retrospective multinational study including SCN diagnosed between 1990 and 2014. RESULTS 2622 patients were included.(More)
BACKGROUND When enucleation is too risky because of possible damage of the main pancreatic duct, benign tumors located in the neck or body of the pancreas are usually removed by a left (spleno)-pancreatectomy or by a pancreatoduodenectomy. But standard pancreatic resection results in an important loss of normal pancreatic parenchyma and may cause impairment(More)
The aim of this study was to discover whether MCP-1/CCL2, a CC chemokine able to attract macrophages, is expressed in human pancreatic cancer and how it modulates cancer progression. All primary tumors were tested, and 6 of 14 pancreatic cancer cell lines were constitutively secreted CCL2. Analysis of the regulation demonstrated that the expression of CCL2(More)
A retrospective study was performed of 113 patients who underwent surgical resection of carcinoma of the pancreas from 1970 to 1992. The postoperative mortality rate was 15 per cent (5 per cent in the last 11 years). The actuarial 5-year survival rate was 12 per cent. Survival was significantly influenced by age (P = 0.03), vascular resection (P = 0.02),(More)
The differential diagnosis between benign and malignant pancreatic cystic lesions may be very difficult. We recently found that F-18-.uorodeoxyglucose positron emission tomography (18-FDG PET) was useful for the preoperative work-up of pancreatic cystic lesions. This study was undertaken to confirm these results. From February 2000 to July 2003, 50 patients(More)
OBJECTIVE To assess the reliability of 18-fluorodeoxyglucose positron emission tomography (18-FDG PET) in distinguishing benign from malignant cystic lesions of the pancreas. SUMMARY BACKGROUND DATA The preoperative differential diagnosis of cystic lesions of the pancreas remains difficult: the most important point is to identify malignant or premalignant(More)
Solid-pseudopapillary tumor (SPT) is a rare neoplasm of the pancreas that usually occurs in young females. It is generally considered a low-grade malignant tumor that can remain asymptomatic for several years. The occurrence of infiltrating varieties of SPT is around 10%-15%. Between 1986 and 2006, 282 cystic tumors of the pancreas were observed. Among them(More)
