胰头部胰腺实性假乳头状瘤的手术治疗

目的 评价胰头部胰腺实性假乳头状瘤(SPTs)的手术方法及其疗效.方法 总结1999年1月-2009年6月收治的24例胰头部SPTs病例,手术分为肿瘤剜除组(12例)及行胰十二指肠切除或保留幽门胰十二指肠切除术(PD/HPPD)组(12例),回顾性对比分析研究两组的一般资料、手术治疗、术后并发症及预后情况.结果 两组的年龄及肿瘤大小无差异;剜除组手术时间及术中出血量明显少于PD组(P<0.05,P<0.01);剜除组术后并发症略多于PD组,但二者之间无显著性差异.PD/HPPD组明显恶性1例,局部浸润性生长1例.除1例恶性者术后1年复发外,其余患者目前无肿瘤复发.结论 对包膜完整、无明显恶性表现的胰头部SPTs,宜尽量行肿瘤剜除手术治疗.对怀疑恶变的胰头部SPTs,应行标准的胰十二指肠切除术或扩大的胰十二指肠切除术.     

胰腺实性-假乳头状瘤4例报告

对4例胰腺实性假乳头状瘤（SPT）的临床病理资料进行回顾性分析。 4例中3例为女性,年龄15～63（平均23）岁。2例以腹部肿块就诊;1例体检时偶然发现胰腺肿物;1例以腰背部隐痛为主诉入院。肿瘤位于胰头部2例,胰颈体部1例,胰体部1例。肿瘤直径4.5～8.0（平均7）㎝,均有包膜,囊实相间。镜检示,肿瘤由假乳头和囊实区混合组成,瘤细胞围绕纤维血管轴心形成特征性假乳头结构。免疫组化检查,4例Vim,AT阳性,2例NSE阳性。均行手术切除,术后随访0.5~4年,均无复发。提示SPT好发于青少年女性,有独特的临床病理表现,免疫组化提示SPT可能起源于胰腺多潜能干细胞。应视为低度恶性肿瘤。切除率高,预后好。

胰腺实性假乳头状瘤的诊治(附4例)

Objective To discuss the management of solid-pseudopapillary tumor of the pancreas. Methods Four patients of solid-pseudopapillary tumor of the pancreas (SPT) were diagnosed by pathology. One patient was underwent magnetic resonance and two enhanced computer tomography scan. The mass was located in tuberculum (1 case), neck (1 case), and body-tail (2 cases) of pancreases respectively. Four cases were underwent duodenopancreatectomy, local resection of mass, resection of body-tail of pancreases respectively. The maximal diameter of tumor ranged from 5 cm to 16cm, averaged 10.3cm. The blood regular test and biochemistry were normal, and the tumor markers including AFP,CA19-9,CA125,CEA also were normal. The specimens were examined by pathology and immunohistochemistry. Results Four cases all were diagnosed solid-pseudopapillary tumor of the pancreas by pathology. At histologic analysis, the tumor was composed of uniform polygonal cells with moderate to abundant amphophilic cytoplasm and arranged in solid nests with areas of degeneration characterized by separation of the cells into pseudopapillary aggregates with intervening accumulation of mucopolysaccharide rich ground substance. The expressions of Vimentin, α-ACT, α-AAT were positive, and CgA negative. Four cases were followed up for six months and norecurred. Conclusions SPT of pancreases was a kind of tumor of low potential malignancy, and the magnetic resonance and computer tomography were often to be used. The effective therapy was thoroughly resection, and the prognosis in most patients is excellent.

Renal cell carcinoma with concomitant solid pseudopapillary tumor of the pancreas: A case report

INTRODUCTIONSolid pseudopapillary tumor (SPT) of pancreas is an unusual low-grade malignant epithelial tumor that usually occurs in young women and can be treated with surgical resection. Renal cell carcinoma (RCC) is the most common solid lesion of the kidney and primarily a disease of the elderly patient.PRESENTATION OF CASEIn this article we present a case of RCC with concomitant SPT of the pancreas who was treated successfully with a radical nephrectomy and distal pancreatectomy.DISCUSSIONRCC with concomitant SPT may associated in β-catenin gene mutation. But no prior reports have described RCC with concomitant SPT of the pancreas in the same patient.CONCLUSIONTo the best of our knowledge, this is the first report of RCC with concomitant SPT of the pancreas in the same patient.     

胰腺实性-假乳头状瘤22例诊疗体会

目的：探讨胰腺实性-假乳头状瘤（solid pseudopapillary tumor of the pancreas,SPTP）的临床表现特点和治疗方法。方法：回顾性分析2004年1月—2010年11月山东省立医院收治的22例经手术治疗,且术后病理证实为SPTP的患者的临床资料。结果：患者包括21例女性及1例男性,平均年龄为23.4岁。首诊原因多为查体发现胰腺包块而无明显临床症状,另可伴有腹痛、腹胀。影像学检查均提示胰腺或腹腔内边界清楚的实性或囊实性占位病变,CT强化扫描示肿瘤实性部分呈轻、中度强化,囊性部分无明显改变。手术方式包括局部肿瘤切除术8例,胰腺节段切除术2例,胰体尾联合脾脏切除术6例,胰尾部肿瘤切除合并保留脾脏4例,保留十二指肠胰头切除1例,1例发生肝脏转移者行肿瘤局部切除联合肝脏转移瘤切除。术中发现肿瘤分界清楚。除1例发生肝转移外,余患者肿瘤未发现周围器官、血管明显浸润。术后随访无复发及转移。结论：SPTP是一种低度恶性肿瘤,手术是首选治疗方法,尽量首选肿瘤局部切除术,以减少手术创伤。

Liver transplantation for multiple liver metastases from solid pseudopapillary tumor of the pancreas

Solid pseudopapillary tumor (SPT) of the pancreas usually shows a benign clinical course. However, sometimes, distant metastasis may occur. Even in such case, the prognosis is good only if metastatic lesions are resected completely. We report the case of a 14-year-old girl with SPT of the pancreas and unresectable synchronous liver metastasis who underwent successful living donor liver transplantation. For 2 years, she has been disease free. This is the first report on transplantation to relieve liver metastasis of SPT.     

Solid pseudopapillary tumor of the pancreas: a case series of 26 consecutive patients

Objective

Solid pseudopapillary tumor (SPT) of the pancreas, which predominantly affects young women, is a relatively indolent entity with favorable prognosis. The aim of this study is to describe the clinicopathologic features and surgical management of this disease in our institution.

Methods

A retrospective study of clinical data from 26 consecutive patients with SPT managed in a tertiary academic center between January 2002 and December 2007 was performed. Clinicopathologic factors were compared between benign and malignant cases to determine what features of the tumor could suggest malignant potential.

Results

The 26 cases included 22 female and 4 male patients, and the average age was 32.3 years (range 15 to 64). Clinical symptoms were nonspecific and included upper abdominal pain or discomfort, abdominal distention, and back pain. The neoplasm was localized in the pancreatic head/neck in 14 patients and in the body/tail in 12 patients. The median diameter of these lesions was 6.25 cm (range 2 to 15). All of the tumors-including 8 pancreaticoduodenectomies, 10 distal pancreatectomies, 6 local resections, 1 total pancreatectomy, and 1 central pancreatectomy-were resected successfully. No patient received chemotherapy or radiotherapy after surgery. All of the patients except 1 were alive at a median follow-up of 32.5 months (range 3 to 69). One of the 2 patients with malignant SPT, in whom Ki-67 immunoreactivity was >25%, developed local recurrence with liver metastasis 4 months and died 6 months after surgery. There were no significant associations between clinicopathologic factors and malignancy.

Conclusions

SPT is a rare neoplasm with low malignant potential. Characteristic computed axial tomography and magnetic resonance imaging scans combined with age and sex profile should be sufficient for the decision to operate. Patients with malignant SPT should have careful follow-up. The high proliferative index assessed by immunohistochemical staining for Ki-67 may predict poor outcome of malignant SPT.
