Malignant pericardial effusion: sclerotherapy or local chemotherapy?

Management of neoplastic pericardial disease

At present, there is no accurate and effective method for treating neoplastic pericardial effusion. This study analyzed the current literature on the treatment of neoplastic pericardial effusion to provide advice and guidance for clinical treatment. Surgical treatments include pericardial puncture, extension of catheter drainage, pericardial window, and surgical pericardiotomy. Each surgical procedure has a corresponding indication, and the best treatment is selected according to the patient's specific conditions. Systemic chemotherapy is effective in lymphoma and small cell lung cancer that are sensitive to chemotherapeutic drugs. Although pericardial injection of drugs is effective for pericardial tamponade and recurrent pericardial effusion, these methods can only temporarily relieve symptoms and cannot prolong the life of patients. In recent years, immunotherapy, especially adoptive immunotherapy, has achieved good results in the treatment of neoplastic pericardial effusion, thus providing a novel treatment option for neoplastic pericardial effusion.

Prognostic factors and nomogram for cancer-specific death in non small cell lung cancer with malignant pericardial effusion

Background

The prognosis of lung cancer with malignant pericardial effusion is very terrible owing to the impact of cardiac tamponade. The aim of our study seeks to identify prognostic factors and establish a prognostic nomogram of non small cell lung cancer (NSCLC) with malignant pericardial effusion.

Methods

NSCLC patients with malignant pericardial effusion between 2010 and 2014 are searched from SEER database.Cancer-specific death of these patients are analyzed through the Kaplan–Meier method, Cox proportional hazard model and competing risk model. Prognostic nomogram of cancer-specific death is performed and validated with concordance index (C-index), calibration plots and internal validation population. Propensity score matching is used to evaluate whether chemotherapy affected the survival of study population.

Results

696 eligible NSCLC patients are involved in the study population, with 22.7% of 1-year survival rate and 8.9% of 2-year survival rate. Laterality, AJCC N, AJCC T, and chemotherapy are regarded as independent prognostic factors of cancer-specific death in the Cox proportional hazards model and competing risk model. The C-index of established nomogram is 0.703(95%CI:0.68–0.73) for cancer-specific death in the study population with acceptable calibration, which is significantly higher than classical TNM stage(C-index = 0.56, 95%CI:0.52–0.60). After 1:1 propensity score matching, chemotherapy potentially reduces the risk of cancer-specific death (HR = 0.42 95%CI: 0.31–0.58) of NSCLC with pericardial effusion.

Conclusions

NSCLC with malignant pericardial effusion harbors low overall survival. One prognostic nomogram based on laterality, AJCC N, AJCC T and chemotherapy is developed for cancer-specific death to predict 1-year and 2-year survival rate with good performance.

Pericardial Effusion in a Dog with Pericardial Hemangiosarcoma

An adult Jack Russel terrier dog presented for evaluation of large-volume peritoneal and pleural effusion. Echocardiography revealed scant pericardial effusion and abnormally thickened pericardium. Electrocardiography revealed complete atrioventricular block with junctional and ventricular escape beats and occasional ventricular premature complexes. Computed tomography of the thorax confirmed diffuse abnormal thickening of the pericardium, and a tentative diagnosis of constrictive-effusive pericarditis was made. The dog underwent subtotal pericardiectomy to remove the parietal pericardium and permanent epicardial pacemaker implantation to manage bradycardia. Based on pericardial histopathology and immunohistochemistry, a diagnosis of pericardial hemangiosarcoma was made. Systemic chemotherapy was initiated with doxorubicin 1 month after surgery. Despite initial improvement with chemotherapy, the dog was euthanized 4 months after surgery because of development of recurrent pleural effusion. To the author's knowledge, this is the first case report in dogs to describe isolated pericardial location of hemangiosarcoma resulting in constrictive-effusive pericarditis.

Determinants of Survival After Emergency Intrapericardial Cisplatin Treatment in Cancer Patients with Recurrent Hemodynamic Instability After Pericardiocentesis

BACKGROUND

Pericardial effusion is associated with high mortality in oncology. The etiology of infectious pericarditis and iatrogenic effects of previous radio-/chemotherapy may be always suspected, especially when a subsequent episode is observed.

PATIENTS AND METHODS

The study included 17 hemodynamically-unstable patients with cancer due to recurrent pericardial bloody effusion after previous pericardiocentesis and analyzed survival determinants after intrapericardial chemotherapy with cisplatin.

RESULTS

The mortality rate was not significantly associated with the level of N-terminal pro-B type natriuretic peptide, low hemoglobin (<12 g/dl), elevated white blood cell account (>10⁴/μl), large volume (>1500 ml) and long duration (>8 days) of pericardial drainage, cardiac arrhythmias, positive culture test results nor fever occurring during cisplatin administration. Subsequent systemic anticancer therapy was the strongest factor determining a longer survival (hazard ratio(HR)=0.31, 95% confidence interval(CI)=0.11-0.9; p=0.03).

CONCLUSION

Efficacy of rescue intrapericardial chemotherapy with cisplatin is independent of parameters of hemodynamic instability and levels of inflammatory markers in recurrent pericardial effusion.

Prolonged Drainage and Intrapericardial Bleomycin Administration for Cardiac Tamponade Secondary to Cancer-Related Pericardial Effusion

Malignant pericardial effusion (MPE) is a serious complication of several cancers. The most commonly involved solid tumors are lung and breast cancer. MPE can give rise to the clinical picture of cardiac tamponade, a life threatening condition that needs immediate drainage. While simple pericardiocentesis allows resolution of the symptoms, MPE frequently relapses unless further procedures are performed. Prolonged drainage, talcage with antineoplastic agents, or surgical creation of a pleuro-pericardial window are the most commonly suggested ones. They all result in MPE resolution and high rates of long-term control. Patients suitable for further systemic treatments can have a good prognosis irrespective of the pericardial site of disease. We prospectively enrolled patients with cardiac tamponade treated with prolonged drainage associated with Bleomycin administration. Twenty-two consecutive patients with MPE and associated signs of hemodynamical compromise underwent prolonged drainage and subsequent Bleomycin administration. After injection of 100 mg lidocaine hydrochloride, 10 mg Bleomycin was injected into the pericardial space. The catheter was clumped for 48 h and then reopened. Removal was performed when the drainage volume was <25 mL daily. Twelve patients (54%) achieved complete response and 9 (41%) a partial response. Only 1 (5%) had a treatment failure and underwent a successful surgical procedure. Acute toxicity was of a low degree and occurred in 7 patients (32%). It consisted mainly in thoracic pain and supraventricular arrhythmia. The 1-year pericardial effusion progression-free survival rate was 74.0% (95% confidence interval [CI]: 51.0-97.3). At a median follow-up of 75 months, a pericardial progression was detected in 4 patients (18%). One- and two-year overall survival rates were 33.9% (95% CI: 13.6-54.2) and 14.5% (95% CI: 0.0-29.5), respectively, with lung cancer patients having a shorter survival than breast cancer patients. The worst prognosis, however, was shown in patients not suitable for systemic treatments, irrespective of the site of the primary tumor.Prolonged drainage and intrapericardial Bleomycin is a safe and effective treatment, which should be considered as first choice at least in patients suitable for active systemic treatment.

[Management of malignant pericardial effusion in lung cancer]

Acute pericarditis associated with lung cancer is a relatively frequent complication but is usually not symptomatic unless it causes tamponade. The clinical presentation is classically with dyspnea, thoracic pain, signs of right cardiac failure then left cardiac failure and syncope but it is often a difficult diagnosis in a patient with multi-symptomatic disease. The diagnosis is based on cardiac echography. Toxicity due to radiotherapy or more rarely an infectious etiology must be considered. Clinically significant effusions must be drained because of the high rate of recurrence after a simple aspiration. Drainage is formally indicated when, at echocardiography, the effusion exceeds 20mm in diastole, in cases of tamponade or in cases of compromised hemodynamic status. The formation of a pericardial window at thoracotomy prevents recurrences. Based on old, retrospective, very heterogeneous case series the prognosis, is generally considered to be poor with a median survival which does not exceed 100 days and a one year survival generally lower than 10%. Prognosis is better where diagnosis occurs at an earlier stage allowing regular follow-up and surgical intervention in a non-emergency setting.

Percutaneous balloon pericardiotomy as the initial and definitive treatment for malignant pericardial effusion

INTRODUCTION AND OBJECTIVES

Malignant pericardial effusion has a high recurrence rate after pericardiocentesis. We sought to confirm the efficacy of percutaneous balloon pericardiotomy as the initial treatment of choice for these effusions.

METHODS

Retrospective analysis of the clinical, echocardiographic, and follow-up characteristics of a consecutive series of percutaneous balloon pericardiotomies carried out in a single center in patients with advanced cancer.

RESULTS

Seventeen percutaneous balloon pericardiotomies were performed in 16 patients with a mean age of 66.2 (15.2) years. Fourteen patients had pathologically confirmed metastatic neoplastic disease, 3 had previously required pericardiocentesis, and in the remaining patients percutaneous balloon pericardiotomy was the first treatment for the effusion. All patients had a severe circumferential effusion, and most presented evidence of hemodynamic compromise on echocardiography. In all cases, the procedure was successful, there were no acute complications, and it was well tolerated at the first attempt. There were no infectious complications during follow-up (median, 44 [interquartile range, 36-225] days). One patient developed a large pleural effusion that did not require treatment. Three patients needed a new pericardial procedure: 2 had elective pericardial window surgeries and 1 had a second percutaneous balloon pericardiotomy.

CONCLUSIONS

Percutaneous balloon pericardiotomy is a simple, safe technique that can be effective in the prevention of recurrence in many patients with severe malignant pericardial effusion. The characteristics of this procedure make it particularly useful in this group of patients to avoid more aggressive, poorly tolerated approaches.

Neoplastic pericardial disease in lung cancer: impact on outcomes of different treatment strategies. A multicenter study

BACKGROUND

Local (intrapericardial) chemotherapy has been reported to be useful for the treatment of neoplastic pericardial disease, but it has never been compared to systemic chemotherapy, a combination of the two and simple pericardial drainage or sclerosis.

METHODS

We analyzed the clinical and echocardiographic data of 119 patients, suffering of neoplastic pericarditis due to lung cancer (97 with non-small-cell), comparing the outcomes of four different treatment strategies (extended catheter drainage/sclerosis, systemic chemotherapy, local chemotherapy, and combined - local plus systemic - chemotherapy) at the last available follow-up or at the change of therapy after a treatment failure. The outcomes (based on semiquantitative evaluation of pericardial disease) were classified as complete, partial, no response and progressing disease.

RESULTS

A complete response was achieved in 37/53 of patients with combined, in 12/22 with local, in 5/27 with systemic chemotherapy, respectively, and in 4/17 after drainage/sclerosis (p<0.001). Overall response was achieved in 51/53 with combined, 18/22 and 16/27 with local or systemic chemotherapy, respectively, and in 5/17 with drainage/sclerosis only (p<0.001). Survival was significantly better after combined chemotherapy (p<0.001) and 12/53 patients (23%) in this subgroup survived more than 1 year. The overall response rate was higher with intrapericardial cisplatinum than with other agents (98% vs 80%, χ(2)=7.69, p<0.01).

CONCLUSIONS

Local chemotherapy, alone or with systemic chemotherapy, is effective in treating pericardial metastases from lung carcinoma, leading to a good control of pericardial effusion in 92% of cases, and to complete disappearance of effusion and masses in 65%. Combined therapy is significantly better than any other treatment. Pericardiocentesis and intrapericardial chemotherapy should be used whenever possible in lung cancer neoplastic pericardial disease, not only in case of tamponade.

Neoplastic pericardial disease: Old and current strategies for diagnosis and management

The prevalence of neoplastic pericardial diseases has changed over time and varies according to diagnostic methods. The diagnostic factor is usually the detection of neoplastic cells within the pericardial fluid or in specimens of pericardium, but the diagnosis may be difficult. Accurate sampling and cytopreparatory techniques, together with ancillary studies, including immunohistochemical tests and neoplastic marker dosage, are essential to obtain a reliable diagnosis. The goals of treatment may be simply to relieve symptoms (cardiac tamponade or dyspnea), to prevent recurrent effusion for a long-term symptomatic benefit, or to treat the local neoplastic disease with the aim of prolonging survival. Immediate relief of symptoms may be obtained with percutaneous drainage or with a surgical approach. For long term prevention of recurrences, various approaches have been proposed: extended drainage, pericardial window (surgical or percutaneous balloon pericardiostomy), sclerosing local therapy, local and/or systemic chemotherapy or radiation therapy (RT) (external or with intrapericardial radionuclides). The outcomes of various therapeutic approaches vary for different tumor types. Lymphoma and leukemias can be successfully treated with systemic chemotherapy; for solid tumors, percutaneous drainage and the use of systemic and/or local sclerosing and antineoplastic therapy seems to offer the best chance of success. The use of "pure" sclerosing agents has been replaced by agents with both sclerosing and antineoplastic activity (bleomycin or thiotepa), which seems to be quite effective in breast cancer, at least when associated with systemic chemotherapy. Local chemotherapy with platinum, mitoxantrone and other agents may lead to good local control of the disease, but the addition of systemic chemotherapy is probably relevant in order to prolong survival. The surgical approach (creation of a pericardial window, even with the mini-invasive method of balloon pericardiostomy) and RT may be useful in recurring effusions or in cases that are refractory to other therapeutic approaches.
