Abstract
Several solid lesions can be found within the pancreas mainly arising from the exocrine and endocrine pancreatic tissue. Among all pancreatic malignancies, the most common subtype is pancreatic ductal adenocarcinoma (PDAC), to a point that pancreatic cancer and PDAC are used interchangeably. But, in addition to PDAC, and to the other most common and well-known solid lesions, either related to benign conditions, such as pancreatitis, or not so benign, such as pancreatic neuroendocrine neoplasms (pNENs), there are solid pancreatic lesions considered rare due to their low incidence. These lesions may originate from a cell line with a differentiation other than exocrine/endocrine, such as from the nerve sheath as for pancreatic schwannoma or from mesenchymal cells as for solitary fibrous tumour. These rare solid pancreatic lesions may show a behaviour that ranges in a benign to highly aggressive malignant spectrum. This review includes cases of an intrapancreatic accessory spleen, pancreatic tuberculosis, solid serous cystadenoma, solid pseudopapillary tumour, pancreatic schwannoma, purely intraductal neuroendocrine tumour, pancreatic fibrous solitary tumour, acinar cell carcinoma, undifferentiated carcinoma with osteoclastic-like giant cells, adenosquamous carcinoma, colloid carcinoma of the pancreas, primary leiomyosarcoma of the pancreas, primary and secondary pancreatic lymphoma and metastases within the pancreas. Therefore, it is important to determine the correct diagnosis to ensure optimal patient management. Because of their rarity, their existence is less well known and, when depicted, in most cases incidentally, the correct diagnosis remains challenging. However, there are some typical imaging features present on cross-sectional imaging modalities that, taken into account with the clinical and biological context, contribute substantially to achieve the correct diagnosis.

Abstract
BACKGROUND As a malignant tumor, pancreatic cancer has an extremely low overall 5-year survival rate. Pancreatic adenosquamous carcinoma (PASC), a rare pancreatic malignancy, owns clinical presentation similar to pancreatic ductal adenocarcinoma (PDAC), which is the most prevalent pancreatic cancer subtype. PASC is generally defined as a pancreatic tumor consisting mainly of adenocarcinoma tissue and squamous carcinoma tissue. Compared with PDAC, PASC has a higher metastatic potential and worse prognosis, and lacks of effective treatment options to date. However, the pathogenesis and treatment of PASC are not yet clear and are accompanied with difficulties. CONCLUSION The present paper systematically summarizes the possible pathogenesis, diagnosis methods, and further suggests potential new treatment directions through reviewing research results of PASC, including the clinical manifestations, pathological manifestation, the original hypothesis of squamous carcinoma and the potential regulatory mechanism. In short, the present paper provides a systematic review of the research progress and new ideas for the development mechanism and treatment of PASC.

Abstract
Pancreatic adenosquamous carcinoma (PASC) is a rare pathological subtype of pancreatic cancer (PC), with a worse prognosis than pancreatic ductal adenocarcinoma (PDAC). Due to its rarity, our knowledge of PASC and its biological characteristics are limited. In this review, we provide an overview of the histogenesis, genetic features, diagnosis, treatment, and prognosis of PASC, as well as pancreatic squamous cell carcinoma (PSCC). The information provided here may help to clarify our understanding of PASC and provide useful avenues for further research on this disease.

Abstract
INTRODUCTION Adenosquamous carcinoma of the pancreas (ASCP) is a rare subtype of pancreatic adenocarcinoma. The aim of this study was to investigate the characteristics and outcomes of ASCP in comparison to pancreatic ductal adenocarcinoma (PDAC). MATERIALS AND METHODS All patients with ASCP treated between December 2001 and December 2017 were identified from a prospective database. Clinicopathological and follow-up data were analyzed. A nested case-control-study with matched-pair analysis was performed to compare overall survival of ASCP and PDAC. RESULTS Of 4009 patients undergoing surgery for pancreatic adenocarcinoma 91 patients had ASCP. Compared to PDAC ASCP were larger (4.0 vs. 3.2 cm; p < 0.0001), more frequently involved lymph nodes (88% vs. 78%; p = 0.0216), more frequently showed poor differentiation (G3: 79% vs. 36%; p < 0.0001) and more frequently were located in the pancreatic tail (19% vs. 10%; p = 0.0179). Overall median post-resection-survival was shorter in ASCP (10.8 vs. 20.5 months in PDAC; p = 0.0085), but 5-year survival rates were comparable (18.2% vs. 17.5%). After matching for the unevenly distributed prognostic factors survival after resection of ASCP and PDAC was comparable (p = 0.8301). Localization in the head or several parts of the pancreas, high CA 19-9 levels, and M1 disease were independent predictors of survival in patients with ASCP. CONCLUSION ASCP is more aggressive with poorer differentiation and higher rates of lymph node metastases compared to PDAC. In spite of a shorter median survival, 5-year survival rates after surgical resection of about 18% can be expected in ASCP and support resection as part of a multimodal therapy as the treatment of choice in this rare cancer.

Abstract
BACKGROUND A paucity of data exists regarding the natural history and outcome measures of adenosquamous carcinoma of the pancreas (ASCP), a histology distinct from pancreatic adenocarcinoma (PDAC). The aim of this study is to characterize the clinicopathological features of ASCP in a large cohort of patients comparing outcome measures of surgically resected patients to PDAC. METHODS We identified patients diagnosed with ASCP or PDAC from the National Cancer Database from 2004 to 2012. Patient demographics, tumor characteristics, treatment regimens, and overall survival were analyzed between the groups. RESULTS We identified 207 073 patients: 205 328 (99%) in the PDAC group and 1745 (1%) in the ASCP group. ASCP tumors were larger, located more frequently in a body/tail location (36% vs 24%, P < 0.001), undifferentiated/anaplastic histology (41% vs 17%, P < 0.001), and early stage presentation, (39% vs 32%, P < 0.001). There was no significant difference in OS when comparing all patients with PDAC and ASCP (6.2 months and 5.7 months, P = 0.601). In surgical patients ASCP histology was associated with worse OS (14.8 months vs 20.5 months, P < 0.001) but had lower nodal involvement (55% vs 61%, P < 0.001). ASCP histology was independently associated with worse OS, after adjusting for tumor characteristics, treatment, and patient demographics. In patients with only resected ASCP histology, negative lymph node status, R0 surgical resection, and receipt of chemotherapy was independently associated with improved overall survival following surgical resection. CONCLUSION Although patients with ASCP and PDAC tumors have similar survival when non-surgical and surgical patients are combined, ASCP is associated with worse survival in stage I/II resected patients.

Abstract
When 150 years ago Armand Trousseau proposed that some thrombotic events might be the first sign of concealed visceral malignancies, these findings seemed to be just of anecdotal interest. Since then, however, we have learned that adenocarcinomas, including pancreatic cancers could be associated with a wide spectrum of paraneoplastic syndromes. They may precede the detection of the tumor, may occur simultaneously or may develop during its progression. Due to various hematologic, endocrine, cutaneous, articular, neuromuscular, renal or even psychiatric syndromes, their correct interpretation is intriguing, and because their early signs are not necessarily recognized first by oncologists, the paraneoplastic syndromes pose a diagnostic challenge. Unfortunately, we cannot generalize about their mechanisms, because the molecular backgrounds are far-reaching. In most of the cases, the pancreatic cancer cells release various factors into the bloodstream triggering the coagulation cascade. These patients frequently present with venous thromboembolism, and sometimes they are resistant to anticoagulation. The simultaneous thrombotic and bleeding evens do reflect the abnormal hemostasis. In other instances autoantibodies are formed against cutaneous, renal, neuromuscular or nervous tissues, but the mechanism of some syndromes remains unclear. Clinicians should be aware that pancreatic carcinoma may be associated with not just the Trousseau-syndrome.

Abstract
Adenosquamous carcinoma of the pancreas (ASCP) is a rare entity. Like adenocarcinoma of the pancreas, overall survival is poor. Characteristics of ASCP include central tumor necrosis, along with osteoclasts and hypercalcemia. Various theories exist as to why this histological subtype exists, as normal pancreas tissue has no benign squamous epithelium. Due to the rarity of this disease, limited molecular analysis has been performed, and those reports indicate unique molecular features of ASCP. In this paper, we characterize 23 patients diagnosed with ASCP through molecular profiling using immunohistochemistry staining, fluorescent in situ hybridization, chromogenic in situ hybridization, and gene sequencing, Additionally, we provide a comprehensive literature review of what is known to date of ASCP. Molecular characterization revealed overexpression in MRP1 (80%), MGMT (79%), TOP2A (75), RRM1 (42%), TOPO1 (42%), PTEN (45%), CMET (40%), and C-KIT (10%) among others. One hundred percent of samples tested were positive for KRAS mutations. This analysis shows heretofore unsuspected leads to be considered for treatments of this rare type of exocrine pancreas cancer. Molecular profiling may be appropriate to provide maximum information regarding the patient’s tumor. Further work should be pursued to better characterize this disease.

Abstract
BACKGROUND AND OBJECTIVE There is a relative scarcity of reports to evaluate the associations between serum calcium level and the prognosis in patients with pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to determine whether serum calcium level is a significant predictor for survival in PDAC patients. METHODS This is a retrospective cohort study. The clinicopathological characteristics, preoperative serum calcium levels and the survival data of 114 patients who underwent surgery for PDAC between January 1, 2009 and January 31, 2012 were collected. The associations between serum calcium level and overall survival were evaluated using the multivariate Cox proportional hazards model. RESULTS The median age of the patients was 60 years, and 64 (56.1%) of them were male. Eighty-one cases (71.1%) were dead at the last follow up. Forty-four patients (38.6%) died within the first year after surgery. The receiver operating characteristics (ROC) curve indicated a significant result for serum calcium level in predicting one-year death after surgery [area under the curve (AUC), 0.629; 95% CI 0.527-0.730, P=0.021]. In multivariate analysis, higher serum calcium levels [hazard ratio (HR), 1.922; P=0.036], diabetes (HR, 1.820; P=0.017), histologically poorly-differentiated tumor (HR, 3.342; P=0.001) and vessel invasion (HR, 1.729; P=0.023) were independent predictors of poor prognosis. Similarly, the albumin-adjusted albumin level was also an independent prognostic factor. CONCLUSIONS The higher serum calcium level is associated with poor prognosis in patients with resectable PDAC and the level of serum calcium can predict death within one year after surgery.

Abstract
BACKGROUND Pancreatic adenosquamous carcinoma has historically been characterized as having a more aggressive clinical course than ductal adenocarcinoma. The natural history of this disease, however, is essentially unknown. METHODS We evaluated the clinical characteristics of all patients with pancreatic adenosquamous carcinoma recorded in the California Cancer Registry 2000-2007 and compared them to those of patients with ductal adenocarcinoma. RESULTS Ninety-five patients with pancreatic adenosquamous carcinoma and 14,746 patients with ductal adenocarcinoma were identified. Demographics were similar between subtypes (p > 0.05). Disease stage at presentation was also similar; over 50% of each diagnostic group presented with metastatic disease (p = 0.62). Surgical resection was more common among patients with locoregional adenosquamous carcinoma than adenocarcinoma (p = 0.0004), but rates of adjuvant therapy administration were similar (p > 0.05). The cohorts' median overall survival durations were similar in a Cox proportional hazards model (p = 0.45); overall survival was also similar when only patients with resected disease were considered (p = 0.65). Early stage, resection and receipt of radiation or chemotherapy were favorable independent prognostic factors among patients with adenosquamous carcinoma. The median overall survival duration of patients with resected adenosquamous carcinoma was 12 months (95% CI, 8-52). CONCLUSIONS Adenosquamous carcinoma has a natural history similar to that of ductal adenocarcinoma when treated with prevalent clinical patterns of care.

Abstract
Among exocrine pancreatic tumors, adenosquamous carcinoma (ASC) is a rare, aggressive subtype with a worse prognosis and a higher potential for metastases compared to its more conventional glandular counterpart, adenocarcinoma. The disease distribution shows an approximately 1:1 male/female ratio and a median survival of circa five months. Although such features as central necrosis and hypervascularity are suggestive of pancreatic ASC, more research is necessary to identify other, more specific markers for this tumor subtype. Humoral hypercalcemia of malignancy has also been described with ASC of the pancreas, likely as a result of PTHrP production by the squamous component of the tumor. Similar to the therapeutics of pancreatic adenocarcinoma, adjuvant chemotherapy or chemoradiotherapy is currently indicated for resectable ASC of the pancreas, while gemcitabine or gemcitabine combinations are used for a more advanced disease. Both pathologic and molecular features of pancreatic ASC characterize it as a distinct subtype of pancreatic cancer. As a result, its molecular and genetic makeup could be exploited for both diagnostic and therapeutic quests in the future.

Abstract
PURPOSE Adenosquamous pancreatic cancer represents 0.9-4.4% of exocrine pancreatic neoplasms and is generally thought to be associated with a worse prognosis than the more common ductal adenocarcinoma. The aim of the current study is to describe the outcome of patients with adenosquamous pancreatic cancer in our institution who were managed in a multidisciplinary environment. METHODS In a retrospective analysis between February 1990 and February 2010, we identified from our database of 890 pancreatic lesions resected for malignancy six cases (0.67%) of adenosquamous cancer. We assessed the demographics, clinical and radiological features, surgical approach, histological details and follow-up data. RESULTS All patients underwent pylorus-preserving pancreatoduodenectomy. Two patients, one male and one female, died in the preoperative period due to sepsis and myocardial infarction, respectively. The remaining four patients received adjuvant chemotherapy. One male patient died with local recurrence after 13 months; however, one female and two male patients are still alive with Karnofsky status of 80-90% at 15, 14 and 39 months after the operation, respectively. CONCLUSIONS The prognosis of adenosquamous pancreatic cancer remains very poor, apparently worse than ductal pancreatic cancer. Nevertheless, our report and the review of literature seem to show that "curative" surgical resection associated with adjuvant treatment may offer the best results with a similar survival rate than ductal pancreatic cancer.
