RESUMO
Trousseau syndrome, also known as thrombophlebitis migrans or migratory superficial thrombophlebitis, is a rare but significant paraneoplastic manifestation associated with various cancers. This syndrome is characterized by the occurrence of recurrent deep or superficial venous thrombosis in patients with malignancies. Patients with cancer have a greatly increased risk of venous thrombosis, especially in the first few months after diagnosis and in the presence of distant metastases. This article describes the case of a 72-year-old female patient who suffered a deep vein thrombosis in the right lower limb, which led to Trousseau syndrome secondary to non-Hodgkin's lymphoma.
RESUMO
There are limited reports on patients with Trousseau syndrome, a condition characterized by hypercoagulability associated with malignant tumors, initially manifesting with reduced visual function. We present a case of a patient who experienced bilateral vision loss and was subsequently diagnosed with Trousseau's syndrome following examination and investigations. A 70-year-old man, undergoing chemotherapy for advanced pancreatic cancer, reported decreased visual acuity in both eyes. A dilated fundus examination revealed retinal pigment epithelial atrophy in the posterior pole and cotton-wool spots. Optical coherence tomography exhibited partial disruption of the ellipsoid zone in the parafoveal region, and full-field electroretinogram results were subnormal, although the macular retinal structure was preserved. Brain magnetic resonance imaging (MRI) detected occipital lobe infarction. Elevated coagulability markers, including D-dimer (5.5µg/mL), led to the diagnosis of Trousseau's syndrome. In cases where patients with malignant tumors present with profound visual loss, considering the possibility of Trousseau's syndrome and conducting assessments of brain function and coagulability is crucial for accurate diagnosis and appropriate management.
RESUMO
Trousseau syndrome is characterized by cancer-associated systemic thrombosis. We describe the first case of a successfully treated gallbladder adenocarcinoma accompanied by Trousseau syndrome. A 66-year-old woman presented with right hemiplegia. Magnetic resonance imaging identified multiple cerebral infarctions. Her serum carbohydrate antigen 19-9 and D-dimer levels were markedly elevated, and a gallbladder tumor was detected via abdominal computed tomography. Venous ultrasonography of the lower limbs revealed a deep venous thrombus in the right peroneal vein. These findings suggested that the brain infarctions were likely caused by Trousseau syndrome associated with her gallbladder cancer. Radical resection of the gallbladder tumor was performed. The resected gallbladder was filled with mucus and was pathologically diagnosed as an adenocarcinoma. Her postoperative course was uneventful, and she received a one-year course of adjuvant therapy with oral S-1. No cancer recurrence or thrombosis was noted 26 months postoperatively. Despite concurrent Trousseau syndrome, a radical cure of the primary tumor and thrombosis could be achieved with the appropriate treatment.

Trousseau syndrome (TS) is a malignant tumor-mediated complication of the hypercoagulable state with an unknown etiology. Laboratory testing results in patients with TS have indicated elevated D-dimer levels. The imaging analysis in patients who had undergone stroke has shown the presence of several cerebral infarction lesions in multiple regions. Since patients have had malignant tumors for a long time when they suffer from a secondary stroke, the optimum time for radical tumor treatment is usually missed. This study reports a case to improve the early screening and detection of TS and reduce the risk of recurrence of cerebral infarction.
RESUMO
Background: Trousseau syndrome (TS) is a thromboembolic event in cancer patients caused by abnormalities in coagulation and fibrinolytic mechanisms. Acute multiple cerebral infarction (AMCI) is a rare form of TS. This study aimed to discuss the differentiation of clinical and radiographic characteristics between TS and cardiogenic embolism (CE) with AMCI as the main manifestation. Methods: We retrospectively analyzed 69 patients with TS-AMCI and 105 patients with CE-AMCI who were treated at Shandong Provincial Hospital between August 2018 and October 2022. The clinical baseline data, laboratory indices, and imaging characteristics of the two groups were compared. A logistic regression was used to analyze the risk factors of TS-AMCI, and receiver operating characteristic (ROC) curves were used to analyze the predictive value of the risk factors. Results: In relation to the clinical data, there were statistically significant differences between the two groups of patients in terms of the lipid and coagulation indices. D-dimer [odds ratio (OR) =4.459, 95% confidence interval (CI): 1.871-10.625; P=0.001] and triglyceride (OR =6.001, 95% CI: 2.375-15.165; P<0.001) were independent risk factors for TS-AMCI. In relation to the radiographic characteristics, the infarctions in the TS-AMCI group were widely distributed in multiple arterial supply areas [23 (33.3%) vs. 10 (9.5%); P<0.001]. More importantly, bilateral anterior + posterior circulation was also an independent risk factor for TS-AMCI (OR =15.005, 95% CI: 1.757-128.17; P=0.013). Conclusions: Unexplained AMCI in the cancer-prone age group, abnormalities in the lipid and D-dimer levels, and infarction foci involving multiple arterial blood supply areas suggested a high probability of TS.
RESUMO
BACKGROUND: Trousseau syndrome (TS) is relatively rare and easily overlooked by clinicians, causing misdiagnosis and affecting subsequent treatment. OBJECTIVE: In this study, clinical features, laboratory examination, imaging features, treatment, and prognosis of patients with TS were discussed. METHODS AND MATERIAL: From February 2018 to April 2022, cases of 21 patients with malignant tumors complicated by acute ischemic stroke (AIS) were admitted to the Neurology Department of the hospital, and were retrospectively analyzed and discussed based on the literature. RESULTS: Twenty-one cases were included in the study. Of these, 95.23% (20/21) developed AIS 6-21 months after the onset of malignant tumors, 9.52% (2/21) had ischemic stroke as the first symptom, 4.76% (1/21) had recurrent ischemic stroke, and 14.29% (3/21) subsequently experienced venous and arterial thrombosis events; 80.95% (17/21) were pathologically confirmed to have adenocarcinoma; and 90.47% (19/21) of infarction cases involved multiple blood vessel feeding sites. MRI showed multiregional, multifocal patchy infarcts. D-dimer concentration was higher than normal in all patients. In addition, 61.90% (13/21) of the patients had poor outcomes according to mRS. CONCLUSION: TS is a rare clinical type. It is often associated with adenocarcinoma, and the treatment is different from that of conventional cerebral infarction and the prognosis is very poor. In clinical practice, for AIS of unknown cause, if MRI shows multiple small lesions accompanied by a significant increase in D-dimer, routine screening for latent malignant tumors is recommended.

INTRODUCTION: In patients with cancer-associated hypercoagulability (CAH)-related stroke, D-dimer trends after anticoagulant therapy may offer a biomarker of treatment efficacy. The purpose of this study was to clarify the association between D-dimer trends and recurrent stroke after anticoagulant therapy in patients with CAH-related stroke. METHODS: We performed retrospective cohort study of consecutive patients with CAH-related stroke at two stroke centers from 2011 to 2020. The ratio of posttreatment to pretreatment D-dimer levels (post/pre ratio) was used as an indicator of D-dimer trends after anticoagulant therapy. Fine-Gray models were used to evaluate the association between post/pre ratio and recurrent stroke. RESULTS: Among 360 acute ischemic stroke patients with active cancer, 73 patients with CAH-related stroke were included in this study. Recurrent stroke occurred in 13 patients (18%) during a median follow-up time of 28 days (interquartile range, 11-65 days). Multivariate analysis revealed that high post/pre ratio was independently associated with recurrent stroke (per 0.1 increase: hazard ratio 2.20, 95% confidence interval 1.61-3.01, p = 0.012). CONCLUSION: D-dimer levels after anticoagulant therapy were associated with recurrent stroke in CAH-related stroke patients. Patients with neutral trends in high D-dimer levels after anticoagulant therapy were at high risk of recurrent stroke.

Trousseau syndrome is a paraneoplastic syndrome associated with a risk of poor prognosis. We reviewed the survival time and prognosis of patients with Trousseau syndrome. We identified 40 cases from 28 reports of Trousseau syndrome due to pancreatic cancer. We analyzed 20 cases based on reports providing sufficient information on the stage/location of pancreatic cancer and survival time after Trousseau syndrome. The median survival time was 2.0 months. There was no statistical difference between performance status (PS) 0-1 and PS 4, stages I-III and IV, and pancreatic head and body/tail. However, statistically significant differences were noted between the median survival time of patients who continued treatment for pancreatic cancer even after Trousseau syndrome and those who discontinued treatment (P = 0.005). Although only a small number of cases were analyzed in this study, the results indicated that patients with pancreatic cancer who developed Trousseau syndrome had a poor prognosis, and chemotherapy should be continued, if possible.

Both acute cerebral infarction and malignant tumors are prevalent in the elderly. However, acute cerebral infarction is rarely present as the first clinical manifestation of malignant tumors. By searching the Picture Archiving and Communication System from 2010 to 2022 and the medical record database from 2003 to 2022, we found three cases of Trousseau syndrome, one male and two females with an average age of 69.3 ± 3.2 years, presenting with acute cerebral infarction. Two patients denied having hypertension, diabetes, and coronary heart disease. The average value of the D-dimer was 17.83 ± 12.39 mg/L (normal range, 0 to 0.55 mg/L). Magnetic resonance imaging (MRI) of the brain showed scattered and multiple small infarcts in the watershed area. The sites of infarction were not those that are typically caused by vascular atherosclerosis. One of the females was diagnosed with pancreatic cancer (T2N2M1, stage IV), the male was diagnosed with gastric cancer (T4N3M1, stage IV), and the other female was diagnosed with lung adenocarcinoma (rTxN3M1b, stage IV). The patient with pancreatic cancer underwent a comprehensive geriatric assessment, which revealed that she had a disability, dementia, malnutrition, short life expectancy, and high chemotherapy risk. Ultimately, the patient opted for conservative care, and 3 months after being discharged, she passed away from an acute upper gastrointestinal hemorrhage. Elderly patients with unexplained D-dimer elevation, multiple cerebral vascular lesions detected on MRI, and an absence of typical stroke risk factors need to be monitored for Trousseau syndrome. To screen for cancer, tumor markers and related imaging should be performed first. Trousseau syndrome is primarily treated with chemotherapy, radiotherapy and anticoagulant therapy. The risk of bleeding should be assessed carefully when using anticoagulant therapy in the elderly. Comprehensive geriatric assessment can assist in weighing the benefits and side effects of cancer treatment, making correct medical choices, and improving patients' quality of life.
RESUMO
OBJECTIVE: Stroke is a rare but fatal complication of advanced cancer with Trousseau syndrome, especially as initial symptoms. Here, we report the clinical characteristics, treatment, and prognosis of patients with non-small cell lung cancer (NSCLC) who initially presenting with acute multiple cerebral infarction. METHODS: The clinical characteristics, imaging, treatment, and oncological outcomes of 10 patients diagnosed with Trousseau syndrome and NSCLC between 2015 and 2021 at Guangdong Sanjiu Brain Hospital were retrospectively collected and analyzed. The clinical course of two typical cases were presented. RESULTS: All 10 patients with pathologically confirmed lung adenocarcinoma initially presented with neurological symptoms, including hemiplegic paralysis (7 patients, 70%), dizziness (5 patients, 50%), and unclear speech (3 patients, 30%). The median age was 63.5 years. Eight and two cases were stage III and IV, respectively, at the initial diagnosis. Five patients underwent driver gene testing, revealing three patients with EGFR-sensitive mutations, one patient with ALK fusion, and one patient with wild-type EGFR. All 10 patients received antiplatelet therapy, and six patients subsequently received anti-cancer treatment. The median overall survival of the patients was 8.5 months (95% confidence interval) and 1-year survival rate was 57.1%. Patients who received antitumor treatment, especially those harboring driver gene mutations and received tyrosine kinase inhibitors, had better neurological symptom recovery and superior oncological prognosis (median overall survival, not reached versus 7.4 months, p = 0.038). CONCLUSION: Trousseau syndrome, presenting as multiple cerebral infarctions, is a rare complication of lung adenocarcinoma. Both antiplatelet and antitumor treatment are recommended to achieve better neurological recovery and oncological prognosis in these patients.

Here, we present a 69-year-old female with advanced neuroendocrine carcinoma (NEC) of colon with multiple liver, bone, and kidney metastases who developed Trousseau's syndrome. The patient received etoposide plus cisplatin (EP) as the first-line therapy; however, after single administration of EP, she developed the severe lower-limb edema and EP was considered to be intolerable. Etoposide plus carboplatin was administered as the second-line therapy and after 3 cycles of administration, the progressive disease (PD) was confirmed and 5-fluorouracil + leucovorin + irinotecan (FOLFIRI) plus ramucirumab was administered as the third-line therapy. However, PD was confirmed after 3 cycles of the therapy, and she was to receive the best supportive care and was hospitalized in our hospital. Four weeks after hospitalization, mild impaired consciousness and dysarthria were observed. Blood tests showed coagulation abnormalities including elevation of plasma fibrin/fibrinogen degradation products (FDPs) and D-dimer levels, and the diffusion-weighted image of magnetic resonance imaging (MRI) of the head showed multiple cerebral infarcts. She was diagnosed with Trousseau's syndrome due to the progression of NEC and intravenous unfractionated heparin was administered as anticoagulant therapy. After the administration of heparin, plasma FDP and D-dimer levels decreased; however, due to the progression of NEC, the patient died 6 weeks after hospitalization. This is the first report of NEC of the colon that developed Trousseau's syndrome.
RESUMO
Trousseau's syndrome is a relatively rare reported event in immunotherapy-related clinical trials, mostly occurring in the early period of immune checkpoint inhibitor (ICI) therapy. Here, we report an unusual case of late and lethal Trousseau's syndrome during pembrolizumab maintenance therapy in a lung adenocarcinoma harboring tumor protein p53 (TP53) mutation. The patient has experienced severe coagulation abnormalities manifesting as cerebral infarction, partial infarction of both kidneys and spleen after 23 cycles of pembrolizumab use and was resistant to anticoagulants. The late occurrence of coagulation abnormalities in this case reveals a possible correlation between TP53 mutations and Trousseau's syndrome when patients are treated with ICIs.
In clinical practice, symptoms associated with abnormal coagulation or fibrinolytic function in malignant tumors are known as Trousseau's syndrome. Its main clinical features include cerebral infarction, myocardial infarction, peripheral arterial embolism, etc. Trousseau's syndrome is a relatively rare reported event in immune checkpoint inhibitors (ICIs)-related clinical studies, mostly occurring in the early period of ICI therapy. Here, we report an unusual case of late and lethal Trousseau's syndrome during pembrolizumab, one of the ICI agents, maintenance therapy in a lung adenocarcinoma harboring tumor protein p53 (TP53) mutation. This patient has experienced severe coagulation abnormalities manifesting as cerebral infarction, partial infarction of both kidneys and spleen after 23 cycles of pembrolizumab use and was resistant to anticoagulants. The late occurrence of coagulation abnormalities in this case reveals a possible correlation between TP53 mutations and Trousseau's syndrome when patients are treated with ICIs.

Cancer-associated thrombosis (CAT) is a leading cause of mortality in cancer patients and its incidence varies in different parts of the world. Venous thromboembolism (VTE) is a prominent manifestation of CAT, and significantly impacts morbidity and survival compared to arterial thrombosis in cancer patients. Several risk factors for developing VTE such as chemotherapy and immobilization have also been found co-existing with cancer patients and contributing to the increased risk of VTE in cancer patients than in non-cancer patients. This review highlights recent mechanisms in the pathogenesis of hypercoagulable syndromes associated with cancer, multiple mechanisms implicated in promoting cancer-associated thrombosis and their diagnostic approaches. Cancer cells interact with every part of the hemostatic system; generating their own procoagulant factors, through stimulation of the prothrombotic properties of other blood cell components or the initiation of clotting by cancer therapies which can all directly activate the coagulation cascade and contribute to the VTE experienced in CAT. It is our hope that the multiple interconnections between the hemostatic system and cancer biology and the improved biomarkers reported in this study can be relevant in establishing a predictive model for VTE, optimize early detection of asymptomatic microthrombosis for more personalized prophylactic strategies and incorporate effective therapeutic options and patient management to reduce mortality and morbidity, and improve the quality of life of affected cancer patients.
RESUMO
BACKGROUND: The primary disease of Trousseau's syndrome is often highly advanced cancer, and treatment of the primary disease after cerebral infarction is often difficult. We herein report a case of pancreatic head cancer with Trousseau's syndrome treated with radical resection and anticoagulant therapy. CASE PRESENTATION: A 78-year-old man was admitted with dizziness and diagnosed with cerebral infarction. Abdominal contrast-enhanced computed tomography for a thorough checkup indicated borderline resectable pancreatic head cancer. Radical resection after neoadjuvant chemotherapy (NAC; gemcitabine plus nab-paclitaxel) was scheduled. During the second course of NAC, multiple cerebral infarctions recurred, and the patient was diagnosed with Trousseau's syndrome. Continuous intravenous infusion of heparin was started for cerebral infarction. Since it was impossible to continue NAC and there was no worsening of imaging findings, radical resection was planned. Thereafter, he underwent pancreatoduodenectomy with superior mesenteric vein resection. The patient progressed well and was discharged on the 19th day after surgery. He continued subcutaneous injection of heparin at home and is alive without recurrence of cancer or cerebral infarction at more than 21 months after surgery. CONCLUSION: Surgical treatment may be an option for pancreatic cancer with Trousseau's syndrome under favorable conditions.
RESUMO
INTRODUCTION: We present a case of Trousseau's syndrome in a non-small cell lung cancer patient recurrently aggravated by pembrolizumab. The adverse events related to immune checkpoint inhibitors (ICIs) on thrombogenesis remain unclear. CASE REPORT: A 48-year-old woman was diagnosed with right lung adenocarcinoma (cT1bN3M1a, IVA) and with programmed cell death-1 positive. Brain magnetic resonance imaging (MRI) showed multiple asymptomatic bilateral cerebral infarctions as Trousseau's syndrome. After the patient was administered pembrolizumab, bilateral cerebral infarctions were aggravated. MANAGEMENT AND OUTCOME: Although the patient was given prophylactic anticoagulant therapy respectively before two doses of pembrolizumab, Trousseau's syndrome still aggravated recurrently. DISCUSSION: Trousseau's syndrome is rarely reported following the administration of ICIs. It is possible that pembrolizumab may trigger disorders of the coagulation-fibrinolysis system in cancer patients.

Background: Trousseau syndrome is a hypercoagulability syndrome associated with cancer. It is known that delirium occasionally occurs after the onset of Trousseau syndrome. However, there have been no detailed reports about treatment for psychiatric symptoms of delirium associated with Trousseau syndrome. Case Presentation: A 61-year-old man with lung cancer was hospitalized due to Trousseau syndrome. Delirium occurred after hospitalization and psychiatric symptoms worsened. Although haloperidol, risperidone, and chlorpromazine were used, severe insomnia persisted. After memantine (5 mg/day) was used with perospirone, the patient's psychiatric symptoms gradually decreased; he could sleep for 4-5 h at night. Due to psychiatric improvement, he was able to return home and resume immunotherapy for lung cancer as scheduled. Conclusion: We report the first case of Trousseau syndrome delirium treated by memantine used with perospirone. Although further studies are needed, memantine and perospirone might be candidates for the management of psychiatric symptoms associated with Trousseau syndrome.
RESUMO
Venous thromboembolic disease (VTD) is currently the second leading cause of death in cancer patients with a prevalence of approximately 20% compared with that of 5% in the entire adult population. Cancer patients are a heterogeneous group with significant differences in the risk of VTD which is, in particular, determined by the type of tumour, its extent, location, and the presence of metastases. Some tumours represent a mean 3- to 5-fold increase in risk, while in others the risk of developing VTD is even several times higher. In comparison with non-cancer patients, those with a tumour are not only at an increased risk of an initial thromboembolic event, but also of its recurrence, regardless of ongoing anticoagulation which is associated with a higher risk of bleeding, particularly in mucosal involvement. Venous thrombosis and its treatment may interfere with the ongoing diagnosis and treatment. In cancer patients, VTD is a frequent incidental finding on imaging studies. Primary thromboprophylaxis (apixaban, rivaroxaban, LMWH) is currently recommended in selected groups of cancer patients who are either hospitalized for acute internal disease or immobilized and have an active malignancy, undergo outpatient systemic chemotherapy for a tumour with a high risk of VTD (a Khorana score of 2) or surgery and are not at high risk of bleeding. DOACs should be administered six months after the initiation of chemotherapy. If there is a risk of drug interactions or mucosal bleeding, LMWHs are recommended. At present, DOACs (apixaban, edoxaban, rivaroxaban) and LMWHs are the first-choice drugs in treating VTD. LMWHs are preferred in mucosal tumours, when there is a high risk of bleeding, in progressive malignancy, concomitant emetogenic therapy, and dyspeptic difficulties. In severe renal insufficiency (CrCl < 15 ml/min), vitamin K antagonists may be of value. Individualized treatment should take into consideration the patients general condition, prognosis, and personal preferences.

Diabetes mellitus (type 2 diabetes in particular) and colorectal carcinoma are relatively frequent diseases in our population. At the same time, these units share some common risk factors, for example obesity, lack of physical activity and hyperinsulinemia. Available data show patients with diabetes have increased risk of colorectal adenoma and carcinoma, increased risk of colorectal carcinoma at a lower age, as well as increased risk of relapse and increased mortality with colorectal cancer. The aim of this article is to point out the relationship between diabetes and colorectal carcinoma, with emphasis on the information important for clinical practice, particularly the screening of colorectal carcinoma and lifestyle recommendations for patients with diabetes. Therefore, we offer an overview of the important available publications which consider this topic.
