Metástasis pancreática metacrónica de carcinoma renal / Metachronous pancreatic metastasis from renal cell carcinoma

RESUMEN Las metástasis pancreáticas por carcinoma renal de células claras son excepcionales; en general, se presentan como tumores asintomáticos de diagnóstico incidental. Caso clínico: hombre de 61 años, nefrectomizado hace 10 años; durante el seguimiento se detecta una masa pancreática distal de 3 cm, hipervascular. Se realiza pancreatectomía corporocaudal laparoscópica, confirmándose la presencia de una metástasis de carcinoma renal. Las metástasis pancreáticas del carcinoma renal suelen apare cer en forma asintomática y metacrónica. La resección quirúrgica logra buenos resultados oncológicos y debe intentarse siempre que sea posible. En este caso destacamos que se pudo realizar una exéresis radical mediante abordaje mínimamente invasivo.

ABSTRACT Pancreatic metastases from clear cell renal carcinoma are very rare, and generally present as incidental asymptomatic tumors. Case report: a 61-year-old male patient with a history of nephrectomy 10 years before presented a 3-cm hypervascular mass in the distal pancreas during follow-up. A laparoscopic distal pancreatectomy was performed, confirming the presence of metastasis from a renal cell carci noma. Pancreatic metastases from renal cell carcinoma are usually metachronous and asymptomatic. Surgical resection is associated with favorable oncological results and, if possible, should be attempted. In our case, a successful oncological resection could be performed through a minimally invasive ap proach.

The clinicopathologic features and prognostic analysis of pancreatic metastasis from clear cell renal cell carcinoma / 中华肿瘤杂志

Objective@#To investigate the clinicopathologic features and prognosis of the patients who had clear cell renal cell carcinoma (CCRCC) with metastasis to the pancreas.@*Methods@#From Jan, 2000 to Dec, 2018, 18 patients with clear cell renal cell carcinoma (CCRCC) and had pathologically diagnosed metastasis to the pancreas were enrolled at Peking Union Medical College Hospital. The clinical and pathological data were retrospectively analyzed.@*Results@#11 out of 18 patients were male, and the other 7 were female. The average age of onset of CCRCC was 51.4 years. 8 cases (44.4%) occurred in the left kidney, and the other 10 cases (55.6%) with right kidney tumor. Three patients had synchronous pancreatic metastasis, and the other 15 patients had metachronous pancreatic metastasis. The median time from CCRCC onset to pancreas metastasis was 156 months. The main complaints of pancreas metastasis were abdominal pain, jaundice, gastrointestinal bleeding, nausea, weakness, loss of weight and so on. Seven patients (38.9%) had single lesion of pancreas, while 11 patients (66.1%) had multiple lesions of pancreas. Nine patients (50%) had other organs metastasis besides pancreatic metastasis at the same time. Five patients underwent pancreatic metastasis resection, while 15 patients received oral tyrosine kinase inhibitor(TKI). The mean follow-up was 171.7 months(1~361.5 months) and 5 patients died. The median overall survival (mOS) was 122 months, and the 5 year-survival rate was 81.4%. In univariate analysis, synchronous metastasis to the pancreas, relapse after 10 years, Memorial Sloan Kettering Cancer Center prognostic index, International Metastatic Renal Cell Carcinoma Database Consortium index were all significant parameters for patients′survival.@*Conclusions@#Metastasis to the pancreas from clear cell renal cell carcinoma were rare. These patients had better survival outcomes, especially those relapsing after ten years. Pancreatic metastasis resection had no significant benefit on patient′s survival.

A Retrospective Study of 42 Lung Cancer Patients with Pancreatic Metastases / 中国肺癌杂志

BACKGROUND@#A number of patients with lung cancer have distant metastases at the time of diagnosis. The most common sites for metastases are liver, brain, etc. However pancreatic metastasis is relatively rare, with an insidious onset and poor prognosis. There are no sufficient recognition and attention of lung cancer with pancreatic metastasis. The aim of this study was to summarize the pathological characteristics, clinical manifestations, therapies and prognosis of pancreatic metastases of lung cancer, thus further exploring better managements for the best prolonged survival or quality of life.@*METHODS@#42 patients of lung carcinoma with confirmed pancreatic metastases hospitalized at the Peking Union Medical College Hospital from January 1998 to December 2018 were identified. We reviewed all medical documentations for complete information including diagnosis, treatment, prognosis features.@*RESULTS@#24 (57%) patients were asymptomatic or presented with non-specific symptoms. 18 (43%) patients had symptoms related to pancreatic metastases, such as acute pancreatitis, obstructive jaundice or pain of lumber back. The median overall survival (OS) was 8.8 months. Multivariate analysis suggested patients with symptoms had a poor prognosis compared with patients without pancreatic symptoms [(hazard ratio, HR)=2.645, 95%CI: 1.013-6.910, P=0.047]. Patients received chemotherapy had better prognosis versus those who did not [HR=0.158, 95%CI: 0.049-0.512, P=0.002].@*CONCLUSIONS@#Pancreatic metastasis of lung cancer is rare and the prognosis is poor. Chemotherapy can prolong survival significantly. Local radiotherapy of the pancreas may alleviate local symptoms, improve quality of life, facilitate further systemic chemotherapy for patients to prolong survival. Patients with symptoms related to pancreatic metastases can benefit from the comprehensive treatment of chemotherapy combined with local pancreatic radiotherapy.

Multiple metastatic renal cell carcinoma isolated to pancreas

Renal cell carcinoma (RCC) metastases to the pancreas are reported to be rare. Isolated multiple pancreatic metastases are even rarer. We report a 68-year-old asymptomatic male patient who presented with multiple metastatic nodular lesions in the pancreas demonstrated by computerized tomography 3.5 years after radical nephrectomy performed for clear cell RCC. Spleen-preserving total pancreatectomy was performed. Gross examination revealed fi ve well-demarcated tumoral nodules in the head, body and tail of the pancreas. Histopathological examination revealed clusters of epithelial clear cells, immunohistochemically positive for CD10 and vimentin, and negative for CK19 and chromogranin, supporting a diagnosis of metastatic RCC. The patient has remained well at 29 months post-resection, in agreement with recent experience that radical resection for multiple isolated metastatic nodular lesions can achieve improved survival and better quality of life.

Clinical Characteristics of Pancreatic Metastases / 대한소화기학회지

BACKGROUND/AIMS: Histologically confirmed metastatic pancreatic cancers are infrequent. The aim of this study was to analyze clinical, therapeutic and prognostic features of pancreatic metastases. METHODS: We retrospectively evaluated stage of primary malignancies, interval between diagnosis of primary tumors and detection of pancreatic metastases, treatment for metastases to the pancreas, survival rate, and prognostic factors in 31 patients with pancreatic metastases. RESULTS: The mean age at the time of primary cancer diagnosis was 52.4+/-13.2 years. Primary cancers were renal cell carcinoma (n=16), non-small cell lung cancer (n=6), small cell lung cancer (n=3), colorectal carcinoma (n=2), osteosarcoma (n=1), gastric carcinoma (n=1), malignant melanoma (n=1), and thymic carcinoma (n=1). Pancreatic metastases were synchronous in six cases and metachronous in twenty five cases, with median interval time of 40.8 months (range 3-186) between the diagnosis of primary tumor and detection of pancreatic metastases. The median survival after the detection of the metastases was 16 months. In multivariate analysis, non-renal cell carcinoma as primary malignancy and positive symptom related to pancreatic metastases were associated with poor prognosis (hazard ratio [HR], 8.33; 95% CI, 2.1-33; p=0.003, and HR, 4.02; 95% CI, 1.27-12.7; p=0.018). CONCLUSIONS: Metastatic tumors to the pancreas have to be kept in mind when a patient with pancreatic mass has a history of other malignancy, even if treated several years before. In the absence of widely metastatic disease, aggressive diagnostic and therapeutic approach may offer the chance of long-term survival in selected patients.

Surgical resection of metastasis to the pancreas / 대한외과학회지

PURPOSE: Metastasis to the pancreas is rare, and the benefit of resection for pancreatic metastasis is poorly defined. The aim of this study was to review our experiences of the operative management of metastasis to the pancreas. METHODS: Between 1995 and 2009, 11 patients (8 men and 3 women; median age, 54 years) were admitted to our institution with a metachronously metastatic lesion to the pancreas and later underwent pancreatic resection. The clinical features and outcomes of treatments were examined. RESULTS: The primary cancers were renal cell carcinoma (RCC, n = 7), carcinoid tumor (n = 2), rectal cancer and leiomyosarcoma. Six patients underwent distal pancreatectosplenectomy, 3 pancreaticoduodenectomy and 2 patients underwent enucleation for small RCC. One patient died of metastatic RCC at 53 months after surgery and ten patients remain alive; four patients without disease at 7 to 69 months postoperatively, and the other six with disease at 11 to 68 months. Median postoperative survival of all patients was 34 months. CONCLUSION: Patients with a low surgical risk should be considered for pancreatic metastasectomy if curative resection is possible. Primary cancer type, which is associated with survival benefit, would be the best candidate for surgical resection of metastases to the pancreas.

Metastatic Leiomyosarcoma of the Pancreas Mimicking a Cystic Neoplasm: A Case Report

Pancreatic tumors are primary in most cases. Pancreatic metastases associated with other primary malignancies, especially pancreatic metastasis of leiomyosarcoma, are infrequent. A 49-year-old woman underwent surgical resection of a mass in the right groin, which was diagnosed as a leiomyosarcoma and she was well for 4 years without evidence of disease recurrence. As part of her routine follow-up, an abdominal computed tomography (CT) identified a cystic neoplasm of the pancreas. Pylorus-preserving pancreaticoduodenectomy was performed. Microscopically, the tumor was composed of spindle cells with a predominantly fascicular pattern, which was consistent with a leiomyosarcoma that was metastatic to the pancreas. We report here a unique case of pancreatic metastasis from a leiomyosarcoma, which was resectable and mimicked a primary cystic neoplasm.

Metástase tardia múltipla de carcinoma renal de células claras: relato de caso / Late multiple metastasis from clear renal cell carcinoma: case report

Metástases para o pâncreas são raras, podendo ocorrer a partir do carcinoma renal de células claras. Apresentamos um caso demetástase pancreática, envolvendo suprarrenal e hilo esplênico, em uma mulher de 49 anos, que teve carcinoma renal de células clarassete anos atrás. Em seguimento após nefrectomia, a paciente teve o diagnóstico de metástase em pâncreas, suprarrenal e hiloesplênico. Tratada com cirurgia e interferon. Imunohistoquímica para gp200 e CD-10, foi positiva. Tomografia computadorizada mostroumetástase para o estômago oito anos após a nefrectomia, estando a paciente em uso de interferon atualmente. Carcinoma de célulasrenais pode recidivar anos após a nefrectomia. Identificação e tratamento cirúrgico podem proporcionar suporte paliativo e sobrevidaem longo prazo.

Metastasis to the pancreas is uncommon; however, it may occur from clear renal cell carcinomas. We present a case of pancreaticmetastasis involving adrenal and splenic hilum in a 49 year-old woman that had clear renal cell carcinoma seven years ago. The patientin post nephrectomy follow-up presented a diagnosis of metastasis in the pancreas, adrenal and splenic hilus. The patients was treatedby surgery and interferon. Immunohistochemistry for gp200 and CD-10 was positive and computed tomography showed metastasis inthe stomach eight years after surgery. She is currently treated with interferon. Renal cell carcinoma can reappear years afternephrectomy, therefore, recognition and surgical treatment can provide palliation and long-term survival.

A Case of Non-small Cell Lung Cancer Presenting as Abdominal Pain and a Pancreatic Nodule / 결핵및호흡기질환

Lung cancer frequently metastasizes to distant organs. However, solitary metastasis to the pancreas, with lung cancer as the source, is very rare. Most metastatic cases of the pancreas tend to be discovered in patients with widely disseminated malignant disease. In addition, patients with pancreatic metastases are often asymptomatic, the metastatic lesions are found incidentally, and are misdiagnosed as primary pancreatic tumors. We described the case of a 63-year-old man who presented with abdominal pain and a pancreatic nodule. The patient underwent resection of primary lung cancer followed by pylorus preserving pancreatoduodenectomy. The pancreatic nodule was confirmed as a solitary metastasis from lung cancer.

Lymphogenous Pancreatic Metastasis of Gastric Cancer Detected by Elevated CA 19-9 Level / 대한소화기내시경학회지

Pancreatic metastasis of gastric cancer almost takes the form of direct continous invasion to the pancreas from the primary lesions or dissemination. Isolated lymphogenous pancreatic metastasis of stomach cancer is rare. A 39-year-old woman was admitted to our institution due to high serum CA 19-9 level. Abdominal computed tomography showed a diffusely enlarged pancreas, and endoscopic retrograde cholangiopancreatography revealed a segmental stricture of pancreatic duct on mid-body. Ultrasonography guided pancreatic biopsy revealed a metastatic poorly differentiated adenocarcinoma with lymphatic tumor emboli. We perfomed esophagogastroduodenoscopy and total colonoscopy. There was a ulcerative lesion at the posterior wall of high body with clubbing change of surrounding mucosal folds. Endoscopic biopsy of the stomach lesion revealed a poorly differentiated adenocarcinoma. Positron emission tomography-computed tomography scan revealed bone metastasis in the sternum. Herein, we report a case of 39 year old female with the diagnosis of gastric adenocarcinoma, with lymphogenous pancreatic metastasis and solitary sternal metastasis detected by elevated serum CA 19-9 level.
