BACKGROUND: Pancreatic cancer is among the most common malignancies associated with venous thromboembolism (VTE). Asian patients are known to have a lower incidence of VTE compared to Caucasian patients. However, few studies have investigated the incidence of VTE in Asian patients with pancreatic cancer. METHODS: This retrospective review of medical records was performed on 505 patients with histopathologically proven advanced stage pancreatic cancer, from January 2006 to December 2012, at Soonchunhyang University Hospitals. RESULTS: Ninety-four patients (18.6%) had at least one pulmonary embolism (PE), deep vein thrombosis (DVT), or splanchnic vein thrombosis (SVT); 38 patients had isolated SVT; and 56 patients (11.1%) had at least one classic VTE (PE and/or DVT of lower extremities). Patients with more advanced stages of pancreatic cancer (distant metastatic stage, recurrence) or who had received chemotherapy had a higher incidence of classic VTE. Patients who were simultaneously diagnosed with pancreatic cancer and classic VTE had a poorer prognosis than patients with subsequent VTEs. There was a significant difference in overall survival (OS) between the presence and absence of a concurrent classic VTE diagnosis (median: OS, 2.1 mo vs. 10.7 mo; P < 0.001). Even when VTE included SVT, the result was similar (P < 0.001). CONCLUSION: In Korean patients with advanced pancreatic cancer, the incidence of VTEs is comparable to that of Caucasian patients. We also found that pancreatic cancer patients with concurrent VTEs had a poor prognosis compared to patients who developed VTEs later.

“Thrombus-in-transit” in pulmonary embolism is associated with high mortality and refers to a free-floating clot in the right atrium or right ventricle, indicating that deep vein thrombosis is present en route to the pulmonary artery. Thrombus entrapped in a patent foramen ovale (PFO) is a rare condition and is associated with paradoxical systemic embolism. Here, we report a case of acute pulmonary embolism with thrombus-in-transit through a PFO in a 68-year-old woman with a diagnosis of metastatic pancreatic cancer undergoing palliative chemotherapy. She presented with syncope after acute onset of exertional dyspnea and was diagnosed with cardiogenic shock due to massive pulmonary embolism with thrombus-in-transit on admission to the emergency room. We treated her with systemic thrombolysis and anticoagulation therapy instead of surgical thrombectomy. We show that hemodynamically unstable pulmonary embolism with thrombus-in-transit entrapped by a PFO may be successfully treated with systemic thrombolysis without paradoxical embolism.

A 22-year-old woman with a 1-month history of shortness of breath that was treated as a case of tuberculosis and pulmonary embolism was referred to the authors’ hospital. Because of the hemodynamic instability in this patient, venoarterial extracorporeal membrane oxygenation (ECMO) was administered in the intensive care unit. She underwent a pulmonary embolectomy for the treatment of progressive circulatory collapse secondary to a pulmonary embolism. The histopathologic result was consistent with a metastatic choriocarcinoma. Despite the surgical management, persistent refractory cardiogenic shock occurred. Subsequently, the patient was treated with chemotherapy in the presence of ECMO and responded well to chemotherapy. She was discharged after 3 months. This case suggests that metastatic choriocarcinoma should be considered as a differential diagnosis in women of childbearing age presenting with a pulmonary embolism, and ECMO may be beneficial in patients with pulmonary embolism for bridging to surgical embolectomy and chemotherapy.

BACKGROUND/AIMS: The diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is difficult for numerous reasons and is related with a poor prognosis. In Korea, the incidence of CTEPH and its clinical features are unknown. Thus, in this study, we evaluated the clinical characteristics and outcomes of CTEPH in a Korean cohort. METHODS: This study included South Korean patients diagnosed with CTEPH between September 2008 and October 2011. Baseline characteristics, treatments and outcomes were analyzed. RESULTS: A total of 134 patients were included in this study with 76 females (56.7%). Their median age was 58.3 +/- 15.9 years and dyspnea (112 patients, 83.5%) was the most common presenting symptom. Sixty-three patients (47%) had a history of acute pulmonary embolism or deep vein thrombosis, and six (4.5%) had pulmonary tuberculosis. In total, 28 patients (21%) underwent pulmonary thromboendarterectomy (PTE), and 99 patients had medical therapy. During the study period, 18 patients (13.4%) died. In a multivariate analysis, higher hemoglobin (relative risk [RR], 1.516; 95% confidence interval [CI], 1.053 to 2.184; p = 0.025) and lower total cholesterol levels (RR, 0.982; 95% CI, 0.965 to 0.999; p = 0.037) were associated with increased mortality. CONCLUSIONS: This was the first national cohort study of Korean patients with CTEPH. Accurate diagnosis, characterization and distributions of CTEPH are imperative for prompt treatment in patients, particularly those undergoing PTE.

Pulmonary artery sarcomas (PAS) are rare malignant neoplasms. Right heart failure due to tumour location is the main cause of death in PAS patients. The hemodynamic influence of PAS may effect prognosis, but this has not been proven. We aimed to identify the clinical characteristics and prognostic factors of PAS in Korea, their association with pulmonary hypertension (PH). PAS patients treated at the Asan Medical Center between 2000 and 2014 were reviewed. We examined demographic characteristics, diagnostic and treatment modalities. Potential prognostic factors were evaluated by univariate and multivariate analysis. Twenty patients were diagnosed with PAS. Ten patients were male, the median age was 54 years (range, 33–75 years). The most common symptom observed was dyspnea (65%). The most common histologic type was spindle cell sarcoma (30%). Ten patients had a presumptive diagnosis of pulmonary embolism (PE) and received anticoagulation therapy. Seventeen patients underwent surgery, but only 5 patients had complete resection. Eleven patients received post-operative treatment (chemotherapy = 3, radiotherapy = 5, chemoradiotherapy = 3). PH was observed in 12 patients before treatment and in 6 patients after treatment. Overall median survival was 24 months. Post-treatment PH was associated with poor prognosis (HR 9.501, 95% CI 1.79–50.32; P = 0.008) while chemotherapy was negatively associated with mortality (HR 0.102, 95% CI 0.013–0.826; P = 0.032) in univariate analysis. Post-treatment PH was also associated with poor prognosis in multivariate analysis (HR 5.7, 95% CI 1.08–30.91; P = 0.041). PAS patients are frequently misdiagnosed with PE in Korea. Post-treatment PH is associated with a poor prognosis.

PURPOSE: This study aimed to investigate clinical characteristics of venous thromboembolism (VTE) in cancer patients. METHODS: We retrospectively analyzed clinical characteristics in patients with VTE confirmed with cancer. Multivariable logistic regression was used to identify differences associated with the development, between the pulmonary embolism (PE) and deep vein thrombosis (DVT) groups. RESULTS: From January 2009 to December 2014, a total of 103 patients with VTE were included in the final analysis: mean age, 70.6+/-11.8 years; female, 56.3%. Most of the patients had a solid cancer (95.1%), and half of all patients had distant metastasis (50.5%). Proportion of patients with VTE who received chemotherapy within a year was 64.1%. Central venous catheters were applied to 59 patients within 6 weeks before the diagnosis of VTE. The proportion of patients with DVT only among VTE patients was 21.4%. In logistic regression analysis, central venous catheter insertion (OR=2.66, 95% CI=1.09, 6.49; p=.032), as well as lung metastasis (OR=2.94; 95% CI=1.06, 8.18; p=.039) were significant predictors for PE rather than DVT only. CONCLUSION: VTE developed in patients with advanced stage cancer. Further studies analyzing the effects of prophylactic anticoagulation in patients with cancer in regards to development of VTE are recommended.
