A systematic review was performed in December 2009 by consulting PubMed MEDLINE for publications and matching the "pancreatic mucinous cystic neoplasm", "pancreatic mucinous cystic tumour", "pancreatic mucinous cystic mass", "pancreatic cyst", and "pancreatic cystic neoplasm" to identify English language articles describing the diagnosis and treatment of the mucinous cystic neoplasm of the pancreas. In total, 16 322 references ranging from January 1969 to December 2009 were analysed and 77 articles were identified. No articles published before 1996 were selected because MCNs were not previously considered to be a completely autonomous disease. Definition, epidemiology, anatomopathological findings, clinical presentation, preoperative evaluation, treatment and prognosis were reviewed. MCNs are pancreatic mucinproducing cysts with a distinctive ovarian-type stroma localized in the body-tail of the gland and occurring in middle-aged females. The majority of MCNs are slow growing and asymptomatic. The prevalence of invasive carcinoma varies between 6% and 55%. Preoperative diagnosis depends on a combination of clinical features, tumor markers, computed tomography (CT), magnetic resonance imaging, endoscopic ultrasound with cyst fluid analysis, and positron emission tomography-CT. Surgery is indicated for all MCNs.展开更多

Methods In this retrospective study, all 12 cases which were diagnosed with suspected prenatal CC,4M over the period in the hospital were analyzed. Information on diagnosis time, types and progression of the lesions during pregnancy, the additional abnormalities, and the outcome of pregnancies were recorded.Results The positive rate of ultrasonic detection of CCAM was about 1.01‰ （1/11 124） before 28 gestation weeks. There were 1 case of type Ⅰ （8%）, 2 cases of type Ⅱ （17%） and 9 cases of type Ⅲ （75%）. Nine pregnancies were terminated and 2 cases were confirmed by pathology. Three neonates were alive and without any symptom now. Conclusions Type Ⅲ is the major type. Ultrasound examination during 20-28 weeks and following up, prenatal consultation, chromosome examination offetus, delivery with a pediatrician standing by, and all suspected neonates being investigated are recommended.展开更多
