A case of Trousseau's syndrome due to intrahepatic cholangiocarcinoma with an extremely high level of CA19-9

Hyperlipidemia as a risk factor for Trousseau syndrome‑related cerebral infarction in patients with advanced gastrointestinal cancer

Trousseau syndrome-related cerebral infarction rarely occurs during chemotherapy in patients with gastrointestinal (GI) cancer, and its clinical features remain unclear. The present study aimed to examine the clinical features of Trousseau syndrome-related cerebral infarction developed during chemotherapy for GI cancer. The present retrospective cohort study consecutively enrolled 878 patients with unresectable GI cancer who received chemotherapy at the Multidisciplinary Treatment Cancer Center, Kurume University Hospital (Kurume, Japan) between April 2014 and March 2020. Patients with colorectal cancer (n=308) were the most common, followed by those with pancreatic (n=242), gastric (n=222) and biliary tract (n=59) cancer, neuroendocrine tumors (n=34) and duodenal cancer (n=11). Among the 878 patients, Trousseau syndrome-related cerebral infarction occurred in 8 (0.9%) patients with a median age of 70.5 years (range, 58–75 years), and 50% of the patients were male (4/8). In total, 3 patients had gastric cancer, 3 had pancreatic cancer and 2 had biliary tract cancer. A greater percentage of patients with Trousseau syndrome-related cerebral infarction had hyperlipidemia (38.0%) than those without (8.2%; P=0.005). Hyperlipidemia was a risk factor for occurrence of Trousseau syndrome-related cerebral infarction with an odds ratio of 7.009 (95% confidence interval, 1.785-27.513). Trousseau syndrome-related cerebral infarction developed during GI chemotherapy was rare and hyperlipidemia may predict its onset.

Young gastric cancer patient with high CA19-9 complicated by Trousseau syndrome

A 47-year-old Japanese woman presented with epigastric discomfort and anorexia. Upper endoscopy showed type 4 advanced gastric cancer in the gastric antrum with stenosis of the pyloric portion. Abdominopelvic CT revealed peritoneal dissemination, and stage IV advanced gastric cancer was diagnosed. Laparoscopic gastrojejunostomy and enterostomy were performed. Trousseau syndrome occurred 7 days post-surgery. Despite appropriate treatment, the patient developed a pulmonary embolism 13 days later and died 18 days post-surgery. Even in young cancer patients without lifestyle disease complications, it is important to pay attention to Trousseau syndrome as part of cancer management.

Risk assessment and prognostic analysis of patients with splenic infarction in emergency department: a multicenter retrospective study

Splenic infarction is a thromboembolic disease that is frequently missed in acute settings. Previous reviews were rarely presented from a clinical perspective. We aimed to evaluate the clinical characteristics, risk factors with diagnostic value, and prognostic factors using large cohort data and a matched case–control study method. A retrospective medical record review of six hospitals in Taiwan from January 1, 2005, to August 31, 2020, was conducted. All patients who underwent contrast CT with confirmed the diagnosis of splenic infarction were included. Their characteristics were presented and compared to a matched control group with similar presenting characteristics. Prognostic factors were also analyzed. A total of 130 cases were included, two-thirds of whom presented with abdominal pain. Atrial fibrillation was the most common associated predisposing condition, followed by hematologic disease. A higher proportion of tachycardia, positive qSOFA score, history of hypertension or atrial fibrillation, leukocytosis, and thrombocytopenia were found in splenic infarction patients compared to their counterparts. An underlying etiology of infective endocarditis was associated with a higher proportion of ICU admission. Splenic infarction patients often presented with left upper abdominal pain and tachycardia. A history of hypertension, atrial fibrillation, a laboratory result of leukocytosis or thrombocytopenia may provide a clue for clinicians to include splenic infarction in the differential list. Among the patients diagnosed with splenic infarction, those with an underlying etiology of infectious endocarditis may be prone to deterioration or ICU admission.

Predictors for thromboembolism in patients with cholangiocarcinoma

BACKGROUND

Patients with cancer are at increased risk of thromboembolic events contributing significantly to cancer-related morbidity and mortality. Because cholangiocarcinoma is a rare type of cancer, the incidence of thromboembolism in this patient population is not well defined.

METHODS

Patients with cholangiocarcinoma treated at the University Cancer Center Leipzig between January 2014 and December 2018 were analyzed retrospectively regarding the incidence of arterial and venous thromboembolism.

RESULTS

A total of 133 newly and consecutively diagnosed patients were included, of whom 22% had stage IV disease. Thromboembolism was diagnosed in 39 (29.3%), with 48% of the events occurring between 60 days prior and 30 days after the initial diagnosis. Arterial thrombosis accounted for 19% and portal venous thrombosis for 33% of the events, while the rest of events occurred in the non-portal venous system. In multivariable analysis, an ONKOTEV score ≥ 2 was the only independent predictor for thromboembolism. Serum CA 19-9 was available in 87 patients (65.4%). In this subgroup, CA 19-9 above the median of 97.7 U/ml and vascular or lymphatic compression were independent predictors for thromboembolism in the first year and CA 19-9 alone remained a significant predictor over the whole observation period. An ONKOTEV score ≥ 2 and increasing age were predictors of survival.

CONCLUSIONS

A very high thromboembolic risk was observed in cholangiocarcinoma, comparable to the risk situation in pancreatic and gastric cancer. The ONKOTEV score and serum CA 19-9 are independent predictors of thromboembolic events. Prospective validation of our observations in this patient population is warranted.

Nonbacterial thrombotic endocarditis as an initial presentation of advanced cholangiocarcinoma in a young patient: A case report

Nonbacterial thrombotic endocarditis, a form of noninfectious thrombotic endocarditis, is mainly characterized by deposition of sterile platelet thrombi on heart valves. Usually, it is observed in advanced malignancy. Herein, we report a case of a previously healthy male with recent unprovoked deep vein thrombosis presented with acute ischemic stroke. The echocardiogram revealed aortic and mitral valve masses. Eventually, he was discovered to have advanced cholangiocarcinoma. The present case, apart from being the youngest reported case, is among the few reported cases which manifest the association between cholangiocarcinoma and nonbacterial thrombotic endocarditis.
