Cystic pancreatic neuroendocrine tumors: Is preoperative diagnosis possible?

Pancreatic neuroendocrine tumors rarely undergo cystic degeneration leading to a radiologic appearance, which is often interpreted as a pancreatic mucinous cystadenoma or pseudocyst. We reviewed our experience with 38 neuroendocrine tumors, four of which were cystic, and 24 other cystic pancreatic tumors (mucinous cystadenoma [n = 5], cystadenocarcinoma [n = 6], serous cystadenoma [n = 3], solid/cystic papillary neoplasm [n = 3], intraductal papillary mucinous tumor [n = 6], and mucinous adenocarcinoma [n = 1]) managed operatively between 1990 and 2000. This review was undertaken to identify clinical and pathologic features useful for preoperative diagnosis of cystic neuroendocrine tumors. Two of the four patients with cystic neuroendocrine tumors presented with abdominal pain, one patient was asymptomatic, and one patient had hypoglycemia. Three of the four cystic neuroendocrine tumors were identified by CT scan, and none were biopsied preoperatively. Preoperative diagnoses included mucinous cystadenoma in two patients (n = 2), pancreatic cystic neoplasm in one patient, (n = 1) and insulinoma in one patient (n = 1). All four cystic neuroendocrine tumors were benign and were completely resected (distal pancreatectomy [n = 2], enucleation [n = 2]). Cystic neuroendocrine tumors are difficult to diagnose preoperatively because the majority of these tumors are nonfunctional, and CT does not differentiate these tumors from other cystic neoplasms. Cystic neuroendocrine tumors represent a subgroup of pancreatic cystic and neuroendocrine tumors with malignant potential. Their high resectability rate further supports the role of surgical exploration and resection in the treatment of pancreatic cystic neoplasms.

Presentation and management of cystic neoplasms of the pancreas

Pancreatic cystic neoplasms are uncommon, but it is important to differentiate them from pseudocysts and ductal adenocarcinoma. A retrospective review was performed to determine distinguishing characteristics and optimal treatment. In 51 patients operated on between 1981 and 1994 at a referral center, the following cystic neoplasms were found: 20 serous cystadenomas, 10 mucinous cystadenomas, 11 mucinous cystadenocarcinomas, five cases of mucinous ducal ectasia, and five papillary cystic neoplasms. Both mucinous ductal ectasia and papillary cystic neoplasms had distinguishing features when compared to other cystic neoplasms. Mucinous ductal ectasia was seen only in men, presented with typical symptoms, and had distinctive features on endoscopic retrograde cholangiopancreatography. Papillary cystic neoplasms occurred in young women (mean age 31 years) and were larger (mean 10.3 cm). Mucinous tumors were always symptomatic, whereas 55% of serous tumors were asymptomatic (P <0.001). The overall rate of resectability was 80%, and there was one operative death (2 %). Intraoperative biopsy was diagnostic in 18 (78%) of 23 cases. An actuarial 5-year survival of 52% was found for resected mucinous cystadenocysticneoplasms. In conclusion, papillary cystic neoplasms and mucinous ductal ectasia have distinct characteristics that differentiate them from other types of pancreatic cystic tumors. Serous cystadenoma should be considered in asymptomatic patients and these patients should be closely observed. Symptomatic neoplasms should be resected with long-term survival expected for malignant forms.

Cystic pancreatic neoplasms: Enucleate or resect?

Asymptomatic cystic pancreatic neoplasms are being detected by abdominal imaging with increasing frequency. Enucleation of small cystic neoplasms can be performed without recurrence but has been associated with a higher incidence of pancreatic fistula. Thus the procedure has been modified to include intraoperative ultrasound imaging and closure of the pancreatic defect. This analysis was performed to determine whether these modifications have improved operative outcome. Thirty patients with mucinous cystic neoplasms (n = 16), serous cystadenomas (n = 10), and cystic islet cell tumors (n = 4) were studied. Enucleation was performed in 11 patients (7 with mucinous cystic neoplasms, 2 with serous cystadenomas and 2 with islet cell tumors), whereas 19 underwent resection of cystic tumors (pancreatoduodenectomy in 8 and distal pancreatectomy in 11). The mean groups did not differ with regard to age (57 years), gender (73% female), presentation (63% incidental), or site (43% head, neck, or uncinate). Patients undergoing enucleation had smaller tumors (2.2 vs. 4.7 cm, P < 0.01) that were less likely to be in the tail (9% vs. 42%). Operative time was significantly shorter in the enucleation group (199 vs. 298 minutes, P < 0.01). Blood loss also was significantly reduced in the enucleation group (114 vs. 450 ml, P < 0.001). Pancreatic fistula rates (27% vs. 26%) and length of hospital stay (12.6 vs. 15.7 days) were similar in the two groupsz. Enucleation of benign cystic pancreatic neoplasms reduces operative time and blood loss without increasing postoperative complications or length of stay. Therefore enucleation should be the standard operation for small benign cystic neoplasms in the uncinate, head, neck, and body of the pancreas.

Mucin-producing pancreatic tumors: A study of nuclear DNA content by flow cytometry

Nuclear DNA content in eight surgically resected mucin-producing pancreatic tumors (MPPT) consisting of two mucinous intraductal adenocarcinomas (MIDAC), two mucinous intraductal adenomas (MIDA), one mucinous cystadenocarcinoma (MCAC), and three mucinous cystadenomas (MCA) were measured by flow cytometry using paraffin-embedded tissue samples. The technique of Shutte was used for the preparation of paraffin-embedded tissue into single dissociated nuclei, while the method of Vindelov was used for staining the isolated nuclei with propidium iodine. Clinicopathologically, the four patients with MIDAC or MIDA were all male and had cystic lesions with a dilated pancreatic duct at the head of the pancreas, while the four patients with MCAC or MCA were all females and had cystic tumors at either the body or tail of the pancreas. All eight patients with MPPT had no metastasis to the regional lymph nodes and were all still alive without recurrence. In an analysis of nuclear DNA content, seven of eight patients had DNA diploid tumors while one patient with a MIDAC perforating the duodenum and choledochus had a DNA aneuploid tumor. Thus, these findings suggest that DNA diploid patterns in MPPT might be associated with a favorable prognosis in MPPT although some patients whose MPPT invaded the surrounding organs might have DNA aneuploid tumors.     

Cystic neoplasms of the pancreas – cystadenomas and cystadenocarcinomas

Introduction: Among the rare cystic pancreatic tumors, serous and mucinous cystadenoma and mucinous cystadenocarcinoma are most often diagnosed. Case: We report on a total of 21 patients with cystic neoplasms who underwent surgery, 11 of whom had mucinous cystadenocarcinoma. Of the 10 remaining patients, serous and mucinous cystadenoma were diagnosed in two groups of five. A common feature of all cystic neoplasms is slow growth, leading to clinical symptoms at an advanced stage, with tumors frequently becoming enormous. Results: In approximately half of the cases, diagnosis was possible by means of ultrasound, computed tomography and, in three instances, by preoperative percutaneous aspiration. Differential diagnosis of pseudocysts proved to be most difficult. Conclusion: Given the low operative risk, resection should always be performed in instances where findings cannot be clearly identified. Moreover, compared with ductal pancreatic carcinomas, the prognosis of a cystadenocarcinoma after early resection is extremely favorable, so that postponing resection might reduce the patient's prospects of being cured.

Non-neoplastic cystic and cystic-like lesions of the pancreas: may mimic pancreatic cystic neoplasms

BACKGROUND: Cystic lesions of the pancreas consist of a broad range of pathological entities. With the exception of the pancreatic pseudocyst, these are usually caused by pancreatic cystic neoplasms. Non-neoplastic pancreatic cystic and cystic-like lesions are extremely rare. In the present article, the surgical experience with these unusual entities over a 14-year period is reported. METHODS: Between 1991 and 2004, all patients who underwent surgical exploration for a cystic lesion of the pancreas were retrospectively reviewed. Patients with a pancreatic pseudocyst were excluded. There were 106 patients of whom 8 (7.5%) had a final pathological diagnosis consistent with a non-neoplastic pancreatic cystic or cystic-like lesion, including 3 patients with a benign epithelial cyst, 2 with a pancreatic abscess (one tuberculous and one foreign body), 2 with mucous retention cysts and 1 with a mucinous non-neoplastic cyst. These eight patients are the focus of this study. RESULTS: There were six female and two male patients with a median age of 61.5 years (range, 41-71 years). All the patients were of Asian origin including seven Chinese and one Indian. Four of the patients were asymptomatic and their pancreatic cysts were discovered incidentally on radiological imaging for other indications. All the patients underwent preoperative radiological investigations, including ultrasonography, computed tomography or magnetic resonance imaging, which showed a cystic lesion of the pancreas. Three patients, all of whom were symptomatic, were diagnosed preoperatively with a malignant cystic neoplasm on the basis of radiological imaging. Two patients were eventually found to have a pancreatic abscess, one tuberculous and the other, secondary to foreign body perforation. The third patient was found on final histology to have chronic pancreatitis with retention cysts. The remaining five patients had a preoperative diagnosis of an indeterminate cyst; on pathological examination, they were found to have a benign epithelial (congenital) cyst (n = 3), retention cyst (n = 1) and mucinous non-neoplastic cyst (n = 1). At a median follow up of 20 months (range, 3-34 months), none of the patients had any evidence of recurrent disease. CONCLUSION: Non-neoplastic cystic and cystic-like lesions of the pancreas are rare causes of pancreatic cystic lesions that are generally benign and do not require surgery when asymptomatic. However, despite advances in diagnostic investigations such as endoscopic ultrasound with fluid aspirate and magnetic resonance imaging, the preoperative diagnosis remains unreliable. Hence, the challenge for all clinicians is to recognize these lesions preoperatively and to avoid 'unnecessary' surgery.     

F-18-fluorodeoxyglucose positron emission tomography in differentiating malignant from benign pancreatic cysts: A prospective study

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 with a pancreatic cystic lesion were prospectively investigated with 18-FDG PET in addition to helical computed tomography (CT) and, in some instances, magnetic resonance imaging (MRI). The validation of diagnosis was based on pathologic findings after surgery (n = 31), percutaneous biopsy (n = 4), and according to follow-up in 15 patients. The 18-FDG PET was analyzed visually and semiquantitatively using the standard uptake value (SUV). The accuracy of FDG PET and CT was determined for preoperative diagnosis of malignant cystic lesions. Seventeen patients had malignant cystic lesions. Sixteen (94%) showed increased 18-FDG uptake (SUV >2.5), including two patients with carcinoma in situ. Eleven patients (65%) were correctly identified as having malignancy by CT. Thirty-three patients had benign tumors: two patients showed increased 18-FDG uptake, and four patients showed CT findings of malignancy. Sensitivity, specificity, positive and negative predictive value, and accuracy of 18-FDG PET and CT in detecting malignant tumors were 94%, 94%, 89%, 97%, and 94% and 65%, 88%, 73%, 83%, and 80%, respectively. 18-FDG PET is accurate in identifying malignant pancreatic cystic lesions and should be used in combination with CT in the preoperative evaluation of patients with pancreatic cystic lesions. A negative result with 18-FDG PET may avoid unnecessary operation in asymptomatic or high-risk patients.
