Patients with unresectable pancreatic cancer (PDAC) or endocrine tumors (PET) often develop splenic vein thrombosis, hypersplenism, and thrombocytopenia which limits the administration of chemotherapy.
From 2001 to 2009, 15 patients with recurrent or unresectable PDAC or PET underwent splenectomy for hypersplenism and thrombocytopenia. The clinical variables of this group of patients were analyzed. The overall survival of patients with PDAC was compared to historical controls.
Of the 15 total patients, 13 (87%) had PDAC and 2 (13%) had PET. All tumors were either locally advanced (n = 6, 40%) or metastatic (n = 9, 60%). The platelet counts significantly increased after splenectomy (p < 0.01). All patients were able to resume chemotherapy within a median of 11.5 days (range 6-27). The patients with PDAC had a median survival of 20 months (range 4-67) from the time of diagnosis and 10.6 months (range 0.6-39.8) from the time of splenectomy.
Splenectomy for patients with unresectable PDAC or PET who developed hypersplenism and thrombocytopenia that limited the administration of chemotherapy, significantly increased platelet counts, and led to resumption of treatment in all patients. Patients with PDAC had better disease-specific survival as compared to historical controls.

    ABSTRACT: The aim of this study is to investigate the efficacy and safety of extracorporeal high-intensity focused ultrasound (HIFU) in treatment of hypersplenism. Fifteen adult dogs, weighing 13-18 kg were divided into three groups: sham group, SVL group undergoing splenic vein ligation (SVL) after laparotomy, and SVL + HIFU group receiving SVL followed by extracorporeal HIFU. Pathologic and hematologic analyses were performed. We also reviewed the clinical data of 19 patients with secondary hypersplenism caused by liver cirrhosis or hepatocellular carcinoma who underwent extracorporeal HIFU. Extracorporeal HIFU significantly diminished the volume of the spleen of animals, coupled with occurrence of coagulation necrosis and fibrosis in the target area. Both platelet and red blood cell counts were significantly restored by HIFU intervention. Similarly, HIFU treatment improved the hematologic parameters in patients with hypersplenism, and no major complications were encountered. Extracorporeal HIFU intervention is effective and safe in managing secondary hypersplenism.

    ABSTRACT: FOLFIRINOX (FFX) was introduced to clinical practice in 2010 following publication of the PRODIGE 4/ACCORD 11 study, which compared this novel regimen to gemcitabine in metastatic pancreatic cancer. Median overall survival, progression-free survival, and objective responses were all superior with FFX and there was improved time to definitive deterioration in quality of life. Despite initial concerns over toxicity, there has been rapid uptake of this regimen, both revolutionizing management and opening the door to innovative research. As experience with FFX has accrued, many questions have arisen including the management of toxicities, the impact of frequent modifications, the optimal number of cycles, integration with other regimens and modalities, interpretation of radiologic and serologic response, utility of molecular signatures, and potential benefit in unique clinical settings such as pre- and postsurgery. This review will closely examine these issues, not only to summarize current knowledge but also to fuel scientific debate. © 2015 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    ABSTRACT: We present a case of a patient with hypersplenism secondary to portal hypertension due to hepato-splenic schistosomiasis, which was accompanied by severe and refractory thrombocytopenia. We performed spleen ablation and measured the total spleen and ablated volumes with contrast-enhanced computed tomography and volumetry. No major complications occurred, thrombocytopenia was resolved, and platelet levels remained stable, which allowed for early treatment of the patient's underlying disease. Previous work has shown that splenic radiofrequency ablation is an attractive alternative treatment for hypersplenism induced by liver cirrhosis. We aimed to contribute to the currently sparse literature evaluating the role of radiofrequency ablation (RFA) in the management of hypersplenism. We conclude that splenic RFA appears to be a viable and promising option for the treatment of hypersplenism.
